RESUMO
Background: Following its introduction in 2018, the Single-Port (SP) robotic platform has been increasingly utilized for various approaches of robotic radical prostatectomy (RARP). Despite the demonstrable benefits in enhancing postoperative outcomes, there has been limited evidence on its perioperative morbidity, especially when compared to the gold-standard multiport (MP). This study sought to compare the perioperative morbidity between SP and MP-RARP. Methods: A retrospective review was performed on 911 patients who underwent RARP between January 2015 and May 2023. At our institution, SP-RARP has been performed since October 2018 with Extraperitoneal and Transvesical (TV) techniques. To reduce the risk of selection bias, only MP-RARP cases performed before October 2018 were included. Baseline clinicodemographic and perioperative parameters were collected. Perioperative complications were classified in accordance to the Clavien-Dindo system with postoperative complications and readmission reported within 90 days of surgery. Statistical analysis was performed with R Packages for Statistical Computing with descriptive statistics as presented. Results: Of the 484 SP and 322 MP-RARP cases included in our analysis, one intraoperative complication was reported, which pertained to a small enterotomy during TV SP-RARP. Postoperative complications were identified in 14.5% and 14.6% of SP and MP-RARP cases (p = 0.989), respectively. Major complication represents 4.1% of the SP and 3.4% of MP cohorts. The 90-day rates of hospital readmission following SP and MP-RARP were 5.6% and 4.9%, respectively (p = 0.717). Limitations of this study included the retrospective single surgeon, single institution nature of our series that also included the early learning curve experience associated with the novel SP platform. Conclusion: This comparative study provided evidence highlighting the low rates of perioperative complication and readmission following SP-RARP that were comparable to the Transperitoneal MP approach. The low morbidity associated with SP-RARP supports its wider application as an addition to the contemporary minimally invasive surgical armamentariums for prostate cancer.

Objective: To evaluate the long-term functional and oncologic outcomes after robotic partial nephrectomy (RAPN) and radical nephrectomy (RARN). Materials and Methods: A retrospective review was performed on 1816 patients who underwent RAPN and RARN at our institution between January 2006 and January 2018. Patients with long-term follow-ups of at least 5 years were selected. Exclusion criteria included patients with a previous history of partial or radical nephrectomy, known genetic mutations, and whose procedures were performed for benign indications. Statistical analysis was performed with results as presented. Results: A total of 769 and 142 patients who underwent RAPN and RARN, respectively, met our inclusion criteria. The duration of follow-up was similar after the two procedures with a median of â¼100 months. The 5- and 10-year chronic kidney disease (CKD) upstaging-free survivals were 74.5% and 65.9% after RAPN and 53% and 46.4% after RARN, respectively. Older age was identified as a potential predictor for CKD progression after RARN, whereas older age, higher body mass index, baseline renal function, and ischemia time were shown to predict CKD progression after RAPN. Renal cell carcinoma-related mortality rates for RAPN and RARN were equally 1.1%. No statistically significant differences were identified in the local recurrence, metastatic, and disease-specific survival between the two procedures. Conclusion: Compared with RARN, RAPN conferred a better CKD progression-free survival. Several factors were identified as potential predictors for clinically significant CKD progression both in the early and late postoperative phase. Long-term oncologic outcomes between the two procedures remained similarly favorable.

ABSTRACT Purpose We investigated the association between preoperative proteinuria and early postoperative renal function after robotic partial nephrectomy (RPN). Patients and Methods We retrospectively reviewed 1121 consecutive RPN cases at a single academic center from 2006 to 2016. Patients without pre-existing CKD (eGFR≥60 mL/min/1.73m2) who had a urinalysis within 1-month prior to RPN were included. The cohort was categorized by the presence or absence of preoperative proteinuria (trace or greater (≥1+) urine dipstick), and groups were compared in terms of clinical and functional outcomes. The incidence of acute kidney injury (AKI) was assessed using RIFLE criteria. Univariate and multivariable models were used to identify factors associated with postoperative AKI. Results Of 947 patients, 97 (10.5%) had preoperative proteinuria. Characteristics associated with preoperative proteinuria included non-white race (p<0.01), preoperative diabetes (p<0.01) and hypertension (HTN) (p<0.01), higher ASA (p<0.01), higher BMI (p<0.01), and higher Charlson score (p<0.01). The incidence of AKI was higher in patients with preoperative proteinuria (10.3% vs. 4.6%, p=0.01). The median eGFR preservation measured within one month after surgery was lower (83.6% vs. 91%, p=0.04) in those with proteinuria; however, there were no significant differences by 3 months after surgery or last follow-up visit. Independent predictors of AKI were high BMI (p<0.01), longer ischemia time (p<0.01), and preoperative proteinuria (p=0.04). Conclusion Preoperative proteinuria by urine dipstick is an independent predictor of postoperative AKI after RPN. This test may be used to identify patients, especially those without overt CKD, who are at increased risk for developing AKI after RPN.

Introduction A duplicated renal collecting system is a relatively common congenital anomaly rarely presenting in adults. Aim In this video we demonstrate our step-by-step technique of Robotic heminephrectomy in a patient with non-functioning upper pole moiety. Materials and Methods Following cystoscopy and ureteral catheter insertion the patient was placed in 600 modified flank position with the ipsilateral arm positioned at the side of the patient. A straight-line, three arm robotic port configuration was employed. The robot was docked at a 90-degree angle, perpendicular to the patient. Following mobilization the colon and identifying both ureters of the duplicated system, the ureters were followed cephalically toward, hilar vessels where the hilar anatomy was identified. The nonfunctioning pole vasculature was ligated using hem-o-lok clips. The ureter was sharply divided and the proximal ureteral stump was passed posterior the renal hilum. Ureteral stump was used as for retraction and heminephrectomy is completed along the line demarcating the upper and lower pole moieties. Renorrhaphy was performed using 0-Vicryl suture with a CT-1 needle. The nonfunctioning pole ureter was then dissected caudally toward the bladder hiatus, ligated using clips, and transected. Results The operating time was 240 minutes and blood loss was 100 cc. There was no complication post-operatively. Conclusions Wrist articulation and degree of freedom offered by robotic platform facilitates successful performance of minimally invasive heminephrectomy in the setting of an atrophic and symptomatic renal segment. .

Purpose To investigate risk factors for urine leak in patients undergoing minimally invasive partial nephrectomy (MIPN) and to determine the role of intraoperative ureteral catheterization in preventing this postoperative complication. Materials and Methods MIPN procedures done from September 1999 to July 2012 at our Center were reviewed from our IRB-approved database. Patient and tumor characteristics, operative techniques and outcomes were analyzed. Patients with evidence of urine leak were identified. Outcomes were compared between patients with preoperative ureteral catheterization (C-group) and those without (NC-group). Univariable and multivariable analyses were performed to identify factors predicting postoperative urine leak. Results A total of 1,019 cases were included (452 robotic partial nephrectomy cases and 567 laparoscopic partial nephrectomy cases). Five hundred twenty eight patients (51.8%) were in the C-group, whereas 491 of them (48.2%) in the NC-group. Urine leak occurred in 31(3%) cases, 4.6% in the C-group and 1.4% in the NC-group (p<0.001). Tumors in NC-group had significantly higher RENAL score, shorter operative and warm ischemic times. On multivariable analysis, tumor proximity to collecting system (OR=9.2; p<0.01), surgeon’s early operative experience (OR=7.8; p<0.01) and preoperative moderate to severe CKD (OR=3.1; p<0.01) significantly increased the odds of the occurrence of a postoperative urine leak. Conclusion Clinically significant urine leak after MIPN in a high volume institution setting is uncommon. This event is more likely to occur in cases of renal masses that are close to the collecting system, in patients with preoperative CKD and when operating surgeon is still in the learning curve for the procedure. Our findings suggest that routine intraoperative ureteral catheterization during MIPN does not reduce the probability of postoperative urine leak. In addition, it adds to the overall ...
