Background: Robot-assisted partial nephrectomy (RAPN) is a standard approach for localized renal cell carcinoma (RCC), emphasizing renal functional preservation. The Minimum Layer Resection (MLR) method, guided by 3D virtual partial nephrectomy (3DvPN) planning, was developed to balance oncological safety with parenchymal preservation. This study evaluated functional and oncological outcomes of RAPN with MLR and identified predictors of renal functional decline. Methods: We retrospectively analyzed 237 patients (after screening 312 cases) who underwent RAPN between 2012 and 2022 with ≥36-month follow-up. 3DvPN planning was used to guide MLR when feasible; both MLR and non-MLR were available and applied throughout the study period according to predefined indications. The primary endpoint was the percentage of estimated glomerular filtration rate (eGFR) preservation at 36 months; a ≥10% decline was clinically significant. Secondary endpoints included perioperative outcomes, acute kidney injury (AKI), and oncological outcomes such as margin involvement and recurrence. Results: The median age was 60 years, tumor size 29 mm, and warm ischemia time 21 min, with selective or superselective clamping achieved in 62.8% of cases. Postoperative AKI occurred in 25.0% (no patient required dialysis). At 3 years, the median eGFR preservation rate was 84.4%, and 28.5% of patients experienced a ≥10% decline. Independent predictors of short-term decline (14 days) were BMI > 25 kg/m2, AKI, and WIT > 25 min, whereas long-term decline (36 months) was associated with tumor size > 30 mm and WIT > 25 min. Margin involvement was 1.7%, recurrence 3.8%, and major complications (Clavien–Dindo ≥IV) occurred in 1.7%. Conclusions: In conclusion, RAPN with the MLR technique under 3DvPN guidance demonstrated favorable perioperative outcomes, acceptable oncologic safety, and good mid-term renal functional preservation (up to 36 months). The approach provides a reproducible surgical strategy that maximizes parenchymal preservation while maintaining negative surgical margins. Prospective multicenter studies with longer follow-up are warranted to confirm long-term durability and to define the role of MLR in routine practice. Full article

Introduction and Objectives: Local recurrence (LR) in patients treated with surgery for renal cell carcinoma (RCC) remains a significant clinical challenge that requires thorough investigation. Our study aimed to identify the relative risk factors and explore the optimal clinical management of LR. Materials and Methods: We conducted a non-randomized, observational, retrospective multicentric registry involving multiple Italian urological centers. We included patients treated with surgery (either nephron-sparing or radical nephrectomy) who later developed LR, defined as recurrence in the ipsilateral kidney or renal fossa. Patients with hereditary syndromes or metastatic disease at the time of LR diagnosis were excluded. Results: We reported 135 cases of LR with the following characteristics: most primary lesions were monofocal (85.7%), with a median size of 42 mm (23–53), the median R.E.N.A.L. score was 7 (6–8), and the median Padua score was 7 (6–9). Patients were treated with robot-assisted techniques in 59% of cases, laparoscopic surgery in 32.4%, and open surgery in 8.6%. Nephron-sparing surgery was performed in 75.2% of cases. Ischemia occurred in 61% of the cases, with a median ischemia time of 21 min (15.5–24). Intraoperative complications occurred in 3.8% of cases, while postoperative complications were reported in 13.8%, all of which were grade ≤3 according to the Clavien–Dindo classification. The primary tumors were pT1a in 43.5% of cases, pT1b in 26.3%, pT2 in 14.7% and pT3 in 15.5%. Histologically, 84% of cases were clear cell, 11.3% papillary type 1 or 2, and 3.7% chromophobe. Sarcomatoid/rhabdoid variants were present in 10.5% of cases. The median rate of LR was 1.3% (range 0.2–3.6), while the median time to LR was 18 months (12–39). LR occurred in the ipsilateral kidney in 70.5% of cases and in the ipsilateral renal fossa in 29.5%. The median rate of PSM in LR cases at initial surgery was 2.4% (range 0–4.3), while the median rate of negative surgical margin (NSM) in LR cases at initial surgery was 0.1 (0–0.3). Following LR diagnosis, most patients (49.2%) underwent surgery, 29.1% received cryoablation or radiotherapy, 17.1% received systemic treatment alone, and 4.6% followed a watchful waiting/active surveillance approach. At a median follow-up of 62 months, the highest oncological control in terms of 5-year cancer-specific survival and overall survival rates was achieved in surgically treated patients. The PSM, the histological variant, and their combination were found to be independent variables correlated with the occurrence of LR, with relative risks of 3.62, 2.71, and 8.12, respectively. Conclusions: LR after nephron-sparing or radical nephrectomy represents a significant clinical dilemma. Known risk factors are not always sufficient to predict recurrence, emphasizing the necessity of consistent radiological follow-up per guideline recommendations. Early detection of recurrence and a multidisciplinary approach involving expert centers are crucial for optimizing patient outcomes. Full article

Introduction: In minimally invasive, off-clamp partial nephrectomy (ocMIPN), the reconstructive strategy profoundly influences functional outcomes. Traditional nephrometry scores aid preoperative planning but do not directly inform the choice of closure technique. This dual-institutional study aimed primarily to identify preoperative CT-derived parameters predictive of renorrhaphy versus a sutureless approach, and secondarily to compare perioperative and functional outcomes between these techniques. Methods: We retrospectively analyzed 201 consecutive ocMIPN cases performed using a standardized off-clamp technique by two experienced surgical teams across robotic platforms and conventional laparoscopy. Preoperative CT scans were centrally reviewed to quantify morphometric features, including contact surface area (CSA), tumor radius, and Gerota’s fascia thickness. Univariable and multivariable logistic regression models—one restricted to radiologic variables and one expanded with RENAL score terms—were generated to identify independent predictors. Perioperative outcomes, renal functional metrics, and Trifecta rates were compared between cohorts. Results: Among the 201 patients, 101 (50.2%) underwent sutureless reconstruction and 100 (49.8%) renorrhaphy. Cohorts were comparable at baseline except for tumor size (3.1 vs. 3.6 cm; p = 0.04). In multivariable analysis, CSA > 15 cm2 (OR 3.93; 95% CI 1.26–12.26; p = 0.02) and tumor radius (OR 1.14 per mm; 95% CI 1.01–1.29; p = 0.04) consistently predicted renorrhaphy, while Gerota’s fascia < 10 mm emerged as significant only in the expanded specification (OR 0.08; 95% CI 0.01–0.70; p = 0.02). Integration with RENAL improved predictive performance (ΔAUC 0.06; NRI 0.14; IDI 0.07), and the final model demonstrated strong discrimination (AUC 0.81) with satisfactory calibration. Perioperative outcomes, postoperative renal function, and Trifecta achievement were similar between groups (all p ≥ 0.21). Conclusions: A concise set of CT-derived morphologic markers—CSA, tumor radius, and perinephric fascia thickness—anticipated reconstructive strategy in ocMIPN and augmented the discriminatory power of RENAL nephrometry. When anatomy was favorable, sutureless repair was not associated with statistically significant differences in perioperative safety or renal function, although the study was not powered for formal equivalence testing. These findings support the integration of radiologic markers into preoperative planning frameworks for nephron-sparing surgery. Full article

Background/Objectives: Small renal masses (SRMs) are being detected more often due to the increasing use of imaging techniques. Many of these lesions are benign or grow slowly, but a small proportion can exhibit aggressive behavior. Several reports have shown that synchronous metastases may occur even in small renal cell carcinomas (RCCs). Our aim is to assess the malignant potential and the metastatic risk of very small RCCs (≤2 cm). Methods: We reviewed consecutive patients who underwent partial nephrectomy for SRMs at our tertiary referral center between 2005 and 2024, focusing on those with a maximum pathologic diameter ≤ 2 cm. Clinical and pathological data were collected, and cases with aggressive features were described. In addition, a literature search on the Medline/PubMed database was performed to identify previously published cases of RCC ≤ 2 cm and to assess their risk of synchronous metastases (SM). Results: Among 578 patients who underwent partial nephrectomy, 116 patients (20%) had tumors ≤ 2 cm, 90 (77.5%) of which were malignant, whereas 22.5% were benign (oncocytoma = 13%; angiomyolipoma = 5%). Median age and tumor size were 51 yrs and 1.7 cm, respectively. Histology showed clear cell (72.2%), papillary (20%), chromophobe (6.6%), and mixed (0.9%). Two patients (2.2%) experienced aggressive disease: one with synchronous metastases and one with recurrence and later progression. From the literature, we identified 16 additional cases of RCC ≤ 2 cm with synchronous metastases and found an important heterogeneity of results regarding the metastatic potential of SRMs. Conclusions: Although uncommon, synchronous metastases can occur in RCCs even smaller than 1–2 cm. Reported rates for SM of SRMs across the literature range between 1% and 13%, with higher risk observed in tumors larger than 3 cm, but without an absolute safe cutoff. Tumor size alone is therefore insufficient to exclude aggressive potential. Clinical decision-making should consider histology, grade, patient age, radiologic features, and emerging molecular markers to guide surveillance and treatment in this growing patient population.

Robotic surgery has become a cornerstone of modern urologic practice, with the da Vinci system maintaining dominance for over two decades. In recent years, however, a new generation of robotic platforms has emerged, introducing greater competition and innovation into the field. These systems aim to address unmet needs through features such as modular architectures, enhanced ergonomics, haptic feedback, and cost-containment strategies. Several platforms—including Hugo™ RAS, Versius™, Avatera™, REVO-I, Hinotori™, Senhance™, KangDuo, MicroHand S, Dexter™, and Toumai®—have entered clinical use with early results demonstrating perioperative and short-term oncologic outcomes broadly comparable to those of established systems, particularly in procedures such as radical prostatectomy, partial nephrectomy, and radical cystectomy. At the same time, they introduce unique advantages in workflow flexibility, portability, and economic feasibility. Nevertheless, important challenges remain, including the need for rigorous comparative trials, standardized training curricula, and long-term cost-effectiveness analyses. The integration of artificial intelligence, augmented reality, and telesurgery holds the potential to further expand the role of robotics in urology, offering opportunities to enhance precision, improve accessibility, and redefine perioperative care models. This review summarizes the evolving landscape of robotic platforms in urology, highlights their clinical applications and limitations, and outlines future directions for research, training, and global implementation.

Background and Objectives: Partial nephrectomy is the standard treatment for small renal tumors, balancing cancer control with renal function preservation. Robot-assisted partial nephrectomy (RAPN) has improved surgical precision and reduced morbidity. Near-infrared fluorescence (NIRF) imaging with indocyanine green (ICG) improves intraoperative visualization of renal vasculature and tissue perfusion, potentially enabling selective arterial clamping to reduce ischemic injury. This study updates contemporary evidence on NIRF/ICG-guided RAPN, focusing on intraoperative, perioperative, and renal function outcomes. Materials and Methods: We systematically queried PubMed, Scopus, and Web of Science databases up to June 2025 for controlled prospective and retrospective studies comparing NIRF/ICG-guided RAPN (selective clamping or zero-ischemia) versus conventional RAPN with main artery clamping in adults with renal masses. Data were synthesized narratively, and random-effects meta-analyses were performed on warm ischemia time (WIT), operative time, estimated blood loss, transfusion rate, length of hospital stay, complication rate, positive surgical margins, and variation in renal function. Results: Eleven studies (10 full-text and one abstract), including two randomized controlled trials, encompassing a patient population of 893 patients (403 NIRF/ICG-guided RAPN and 490 conventional RAPN), were included. Ischemia strategies varied between no clamping, selective or super-selective clamping for NIRF/ICG, and main artery clamping for controls. ICG doses ranging from 3 to 7.5 mg or 0.5–7 mL. Most evidence was classified as level 2b or 3b, indicating a moderate to serious risk of bias. Meta-analysis showed that compared to conventional RAPN, NIRF/ICG-guided RAPN was associated with a shorter WIT (MD: −1.30 min, 95% CI: −2.51 to −0.09; p = 0.039), with no differences in other outcomes. Renal function favored NIRF/ICG at discharge and short-term follow-up, although the difference was not statistically significant. Conclusions: NIRF/ICG reduces WIT during RAPN without increasing perioperative risks. The technique shows promise for better preserving functional outcomes. However, further well-designed, large-scale trials with longer follow-up are needed to confirm these benefits and define clinical indications. Full article

Background/Objectives: The optimal surgical approach for stage I renal cell carcinoma (RCC) in ultra-octogenarians remains debated, especially when balancing oncologic control, renal preservation, and procedural safety. While ablative techniques and active surveillance are often favored in frail patients, robust comparative evidence supporting nephron-sparing surgery in this age group is limited. Methods: We retrospectively reviewed consecutive patients aged ≥80 years who underwent minimally invasive surgery for cT1 clear cell RCC at a high-volume tertiary-care center between July 2001 and August 2025. Patients were stratified into two cohorts: minimally invasive partial nephrectomy (MIPN, n = 51) and radical nephrectomy (MIRN, n = 26). All MIPNs were performed using an off-clamp approach. Baseline, perioperative, functional, and oncologic outcomes were compared. Kaplan–Meier analysis estimated overall survival (OS), cancer-specific survival (CSS), and progression to significant chronic kidney disease (sCKD, defined as CKD stage ≥ 3b). Results: Groups were comparable in age, comorbidities, and ASA score. MIRN patients exhibited higher tumor complexity (RENAL score: 9 vs. 7, p = 0.01) and a greater proportion of pT1b lesions (77% vs. 37.3%, p = 0.01). Perioperative transfusions occurred exclusively in the MIRN group (p = 0.01), whereas complication rates were low and similar between groups. MIPN was associated with significantly higher eGFR at follow-up (48 vs. 30.9 mL/min/1.73 m2, p = 0.01) and a delayed progression to sCKD (p = 0.01), with no differences in OS or CSS at a median follow-up of 30.5 months. Conclusions: In this real-world series of ultra-octogenarians with cT1 clear cell RCC, off-clamp minimally invasive partial nephrectomy ensured superior renal function preservation and delayed progression to sCKD, without compromising oncologic control at mid-term follow-up. Beyond statistical outcomes, these results underscore the importance of tailoring surgical strategies to protect long-term functional autonomy and preserve physiological resilience in elderly patients.

Background and Objectives: Robotic-assisted partial nephrectomy (RAPN) is a preferred minimally invasive option for renal tumours, but its use in highly complex cases (RENAL score ≥ 9) remains underexplored. Only four Asian countries, India, China, South Korea, and Japan, have published studies on RAPN for complex kidney tumours, highlighting limited evidence. The aim of this study is to assess the perioperative, functional, and oncological effects of RAPN for complex renal tumours at a single tertiary centre in Malaysia. Materials and Methods: Patient demographics, tumour characteristics, perioperative parameters, and postoperative results were collected through a retrospective review that was conducted on 35 patients who had undergone RAPN between January 2023 and June 2024. The outcomes were analyzed using descriptive statistics, correlation analysis, and comparative tests between surgical approaches (transperitoneal vs. retroperitoneal). Results: Of the 35 patients, all had high-complexity tumours. RAPN achieved a “trifecta” outcome in 88.6% of patients. Significantly lower intraoperative blood loss is associated with the retroperitoneal approach in comparison with the transperitoneal approach, whereas other perioperative parameters, which include warm ischaemia time, did not show any significant differences. No positive surgical margins were observed, and no local recurrences or port-site metastases were detected during a mean follow-up of 11.31 ± 5.78 months. Postoperative changes in renal function were negligible, with a mean creatinine change of 5.69 ± 20.39 µmol/L. Conclusions: RAPN is a safe and effective option for complex renal tumours, offering excellent functional and oncological outcomes. The choice between transperitoneal and retroperitoneal approaches should be tailored to tumour characteristics for optimal surgical outcomes. This single-centre Malaysian study contributes to the limited Southeast Asian literature on RAPN for complex renal tumours. Full article

Introduction: Intraoperative ultrasound (IOUS) is increasingly utilized in nephron-sparing surgery for its ability to provide real-time, high-resolution imaging that enhances tumor localization and resection accuracy. Its role becomes particularly important in anatomically complex cases such as endophytic, multifocal, or recurrent renal tumors, as well as in patients with a solitary kidney. Methods: We conducted a retrospective analysis of 152 patients who underwent partial nephrectomy for localized renal tumors between January 2019 and December 2024. Patients were divided into two groups: Group A (n = 24) included patients with a solitary surgical kidney or tumor recurrence; Group B (n = 128) included patients with a contralateral functional kidney. IOUS was used in 31 cases (20%). Demographic, perioperative, and oncological outcomes were compared, with specific attention to the use and impact of IOUS. Results: IOUS was significantly more common in Group A (75%) than in Group B (10%) (p < 0.001), reflecting its preferential use in higher-complexity surgeries. The rate of positive surgical margins was low overall, with no significant difference between the IOUS and non-IOUS groups (3.2% vs. 1.7%; p = 0.54). IOUS was more frequently employed in cases involving medium/high RENAL nephrometry scores and multifocal tumors, contributing to improved intraoperative tumor delineation without increasing complication rates. Conclusions: IOUS enhances surgical precision and supports oncologic safety in both robotic and open partial nephrectomies, particularly in complex scenarios. Its use should be encouraged as a standard adjunct in conservative renal surgery, especially in patients with a solitary kidney, recurrent disease, or multifocal tumors. Full article

Background: The potential benefits of prehabilitation in patients undergoing surgery for renal cell carcinoma (RCC) or upper-tract urothelial carcinoma (UTUC) remain unknown. The aim was to evaluate physical function and baseline characteristics over the course of treatment to identify a potential need for prehabilitation. Methods: In this prospective observational study, 62 patients were enrolled—31 undergoing nephrectomies for RCC and 31 undergoing nephroureterectomy for UTUC. Baseline assessments included nutritional screening (NRS 2002), frailty (Clinical Frailty Scale), hemoglobin and iron levels, smoking status, and physical function using the Six-Minute Walk Test (6MWT) and the 30-Second Sit-to-Stand Test (30STS). Functional tests were repeated at hospital discharge and at two-week postoperative follow-up visit. Results: At baseline, 45% of RCC and 68% of UTUC patients were at nutritional risk. Preoperative frailty was present in 20% of the cohort, and 53% had anemia. Functional impairment below the lower limit values (LLVs) was observed in 16% for the RCC and 36% of the UTUC, assessed by 6MWT. The 30 STS revealed that 58% of RCC and 42% of UTUC were below LLV. At discharge, impairment peaked, with 59% and 82% of patients being below the LLVs, respectively. Functional performance partially recovered at follow-up but did not return to baseline levels. Conclusions: Preoperative nutritional deficits, anemia, and functional impairment are prevalent in patients undergoing nephrectomy or nephroureterectomy. A marked postoperative functional decline was identified postoperatively supporting a potential need for early individualized prehabilitation strategies to improve recovery in patients undergoing kidney cancer surgery.

Background: Transplant ureteral stricture (TUS) reconstruction remains a significant challenge in renal transplantation, particularly when conventional access to the transplant ureter and renal pelvis is not feasible. This report presents two rare and complex surgical reconstructions: a combined calico-vesicostomy and uretero-calycostomy in one patient, and an ileo-calycostomy in another. Both cases involved patients with prior failed minimally invasive interventions and complex anatomy that precluded standard repairs. Case presentation: A hybrid surgical approach incorporating open reconstruction with fluoroscopic and endoscopic guidance was used to access the renal calyces directly, enabling successful re-establishment of urinary tract continuity. The first patient underwent dual reconstruction with native ureteral reimplantation to the middle calyx and a simultaneous calycovesicostomy, bladder to the It lower pole calyx. The second patient, with prior ileal conduit urinary diversion, underwent ileocalycostomy—anastomosing the ileal conduit to the middle calyx. Both reconstructions were performed using modified partial nephrectomies to preserve nephron mass. Long-term follow-up (34 and 40 months) demonstrated excellent graft function and minimal complications. Conclusions: These cases represent the first reported long-term outcomes of calycovesicostomy and ileocalycostomy in transplant ureteral reconstruction and reinforce the utility of calyceal access in complex TUSs. These cases highlight rare but viable surgical options in complex scenarios of transplant ureteral strictures. Hence, a multidisciplinary approach and meticulous preoperative planning are essential to optimize outcomes in these challenging scenarios. Full article

The evolution of robotic surgery in urologic oncology has led to the emergence of single-port (SP) robotic systems as a potential alternative to the widely adopted multi-port (MP) platforms. This narrative review provides a comprehensive comparison between SP and MP robotic systems, the former of which received FDA approval in 2018 and CE marking in 2024, focusing on their application across radical prostatectomy, partial and radical nephrectomy, and radical cystectomy. Drawing from the most current literature, we examine perioperative outcomes, oncologic efficacy, postoperative recovery, and complication rates. The review highlights the technical challenges unique to SP surgery, including restricted triangulation, limited instrumentation, and a defined learning curve, while also emphasizing innovations such as transvesical prostatectomy and the Supine Anterior Retroperitoneal Access (SARA) approach. Additionally, we explore the potential impact of emerging technologies—such as artificial intelligence, augmented reality, and telesurgery—on the future of SP platforms. Despite early limitations, SP systems have demonstrated comparable safety and effectiveness in selected cases and may offer unique advantages in specific anatomical scenarios. Continued innovation, structured training, and robust long-term outcome data will be essential for the broader adoption and integration of SP robotic surgery in clinical practice. Full article

Background: Robotic partial nephrectomy (RPN) for posterior renal tumors can be performed via the transperitoneal approach (TA); however, it may provide suboptimal visualization of posterior lesions compared to the retroperitoneal approach (RA). The camera port swapping (CPS) technique was developed to enhance intraoperative visualization and robotic arm maneuverability during TA-RPN. Methods: We conducted a retrospective review of patients who underwent RPN for posterior renal tumors between 2018 and 2024 using either TA with the CPS technique (n = 35) or RA (n = 29). All procedures used the da Vinci Xi surgical system, and the CPS technique involved repositioning the camera port intraoperatively when standard visualization proved inadequate during TA. Propensity score matching (1:1) was performed based on tumor size and body mass index to compare outcomes (n = 21 in each group). Results: Propensity score-matching analysis revealed that body mass index, tumor size, and RENAL nephrometry score were comparable between the two groups. The positive surgical margin was zero in all patients. The warm ischemia time was 22 min (0–44 min) in the TA-CPS group and 18 min (7–45 min) in the RA group (p = 0.504). No complications of Clavien–Dindo classification grade > 3 occurred in the TA-CPS group, while one occurred in the RA group (p = 1.000). Renal function decline was 4.8% in the TA-CPS group and 19% in the RA group (p = 0.343). Trifecta achievement rates were also comparable: 95.2% in the TA-CPS group and 81.0% in the RA group (p = 0.343). Conclusions: Camera port swapping during TA-RPN provided adequate visualization and perioperative outcomes comparable to those achieved with RA-RPN. This may be a practical alternative, particularly for anatomically complex posterior tumors. Full article

Background/Objectives: This study aimed to evaluate and compare the perioperative outcomes of robot-assisted partial nephrectomy (RAPN) for complex renal tumors performed using the novel Japanese Hinotori Surgical Robot System (HSRS) and the established Da Vinci Surgical System (DVSS). Methods: Of 484 consecutive patients who underwent RAPN at our institution, 126 with complex renal tumors were included in the DVSS group, and 48 such patients were included in the HSRS group. Complex tumors in this series were defined by the presence of at least one of the following factors: cT1b, completely endophytic, hilar, cystic, or ipsilateral multiple tumors. Results: Following 1:2 propensity score matching, 74 and 37 patients were included in the DVSS and HSRS groups, respectively. Post-matching, most covariates’ absolute standardized mean difference (SMD) was less than 0.1, indicating effective baseline imbalance correction. All RAPN procedures using HSRS were completed without conversion to open surgery, nephrectomy, or Clavien–Dindo ≥3 postoperative complications. No significant differences in major perioperative outcomes were observed between DVSS and HSRS, including operative time (178 vs. 186 min), console time (115 vs. 115 min; encompassing cockpit time for HSRS), warm ischemia time (15 vs. 15 min), and estimated blood loss (51 vs. 30 mL). Positive surgical margin rates (DVSS 1.4% vs. HSRS 5.4%) and Trifecta achievement rates (94.6% vs. 91.9%) were also comparable, with no significant differences. Conclusions: These findings suggest that, even in patients with complex renal tumors, RAPN performed using the HSRS can achieve perioperative outcomes comparable to those obtained with the established DVSS.

Robotic-assisted surgery has gradually established its role in uro-oncological cases that demand a high level of precision, optimising surgeon ergonomics and decreasing fatigue whilst maintaining optimal clinical outcomes. With the novel Hinotori surgical robot (Medicaroid Corporation (Kobe, Hyogo, Japan)) launched in Japan back in 2019, it has now demonstrated its use case across various clinical series of different surgeries. We sought to narratively synthesise the initial feasibility of the Hinotori robotic system in urology. A systematic, comprehensive literature search was conducted across various databases from September 2024 to October 2024. Relevant keywords within the scope of this study were generated for a more accurate search. After exclusion and removal of duplicates, a total of nine articles were included for review. Among the included studies, one study reported data solely on radical prostatectomy for prostate cancer, two studies reported on robotic-assisted nephroureterectomy for renal tumours, two studies reported on partial nephrectomy performed for renal masses, two studies reported on radical nephrectomy carried out for renal malignancies and one study reported on robotic-assisted adrenalectomy for adrenal cancer. Lastly, one study collectively reported on outcomes pertaining to partial nephrectomy, partial nephrectomy, vesicourethral anastomosis and pelvic lymph node dissection in a porcine model, as well as partial nephrectomy, radical prostatectomy and pelvic lymph node dissection in cadavers. The current literature supports its non-inferiority to the well-established Da Vinci system, with no major drawbacks or concerns identified when comparing parameters such as intraoperative time, estimated blood loss (EBL), perioperative events (transfusions, conversion to open surgery), length of hospital stay and major postoperative complications. Future studies involving larger cohorts and more complex surgical cases are essential to further evaluate the efficacy and safety of the Hinotori system. The new Hinotori robotic system offers unique three-dimensional features as a non-inferior robotic platform alternative that has proven clinically safe thus far in its use. Larger scale studies and randomised trials are eagerly awaited to assess and validate more holistically its clinical utility. Full article
