RESUMEN
OBJECTIVE: To evaluate the different perioperative variables that may serve as important clinical predictors when selecting patients for outpatient single-port robot-assisted radical prostatectomy (SP-RARP). PATIENTS AND METHODS: A retrospective review was performed on the Institutional Review Board-approved, prospectively maintained database to identify 485 consecutive patients who underwent SP-RARP between 2018 and 2023. A comparison analysis was performed on patients who were managed as outpatients vs inpatients following their respective SP-RARP. A separate analysis was performed after excluding patients with pre-planned admissions to identify the risk factors for unplanned admissions. RESULTS: All procedures were successfully completed without any conversion or additional ports. After excluding patients with pre-planned admissions, outpatient SP-RARP was successfully achieved in 86.6% with a median (interquartile range) length of stay of 4.6 (3.8-6.1) hours. Our multivariate regression analysis identified cardiac comorbidity and preoperative International Prostate Symptom Score (IPSS) as predictors of outpatient SP-RARP. In addition, the absence of cardiac comorbidity, previous abdominal surgery, and lower postoperative pain score were protective against the risk of unplanned admission. Furthermore, both inpatient and outpatient encounters had comparable 90-day rates of postoperative complication (P = 0.136) and hospital re-admission (P = 0.942). CONCLUSION: Outpatient management models could be successfully achieved in most patients who underwent SP-RARP (86.6%) while maintaining similarly low perioperative morbidity profile. Nevertheless, appropriate patient selection based on the baseline clinicodemographic characteristics remains essential to ensure the safety and ongoing success of outpatient SP-RARP.
RESUMEN
PURPOSE: To provide a comprehensive update on the different techniques and outcomes of contemporary Single-Port (SP) Robotic Radical Prostatectomy (RARP) approaches. METHODS: A literature review was performed to identify cohort studies that have utilized the purpose-built SP robotic platform (Intuitive Surgical Inc., Sunnyvale, California) for RARP. All published approaches of SP-RARP were included in our review. Baseline clinical, perioperative, and postoperative oncological and functional outcomes were collected from the included studies. RESULTS: A total of 16 studies involving 1159 patients were identified. To date, five approaches of SP-RARP have been described, namely Transperitoneal, Extraperitoneal, Retzius-Sparing, Transperineal, and Transvesical. The surgical steps and clinical outcomes of the aforementioned approaches were discussed. While operating times were still faster in the Transperitoneal and Extraperitoneal cohorts, the novel and more regionalized Transvesical approach allowed for radical prostatectomy to be pursued in more patients with previous abdominal surgeries and contributed to significantly improved postoperative outcomes, including the earlier return of urinary continence and with most patients being discharged on the same day without any opioids. CONCLUSION: Based on the existing literature, the introduction of SP-RARP not only enriched the repertoire of minimally-invasive surgical treatment options for prostate cancer but also provided the opportunity for urologists to develop new techniques that can improve perioperative outcomes and postoperative quality of life. Given the limited number of patients and heterogeneity in the patient selection and reporting of postoperative outcomes, further research remains necessary to better understand the different benefits and improve patient selection algorithms for the different techniques.

PURPOSE: This study aims to describe the surgical steps for the single-port low anterolateral extraperitoneal approach to pyeloplasty, report its feasibility, and share the initial outcomes of our experience. METHODS: We analyzed all consecutive patients who underwent single-port low anterolateral extraperitoneal pyeloplasty due to ureteropelvic junction obstruction (UPJO). The surgical steps included a pure single-port approach through a 3.5 cm low anterolateral incision two fingerbreadths above the superior pubic ramus. The ureter was localized and followed cranially, a dismembered pyeloplasty was performed, and a running ureteropelvic anastomosis was completed. No drains were placed. The urinary catheter was removed upon discharge, and the ureteral stent after 3-5 weeks. RESULTS: A total of eight cases (two adults and six children) were completed successfully, without complications or conversions. Median operative time, console time, and estimated blood loss were 208.5 min, 114.5 min, and 10.0 ml, respectively. All patients were discharged within 24 h, except for one that required urinary output observation due to retention. There were no major postoperative complications. The median pain score at discharge was 0/10. Only one patient was prescribed PRN opioids at discharge. The readmission rate was 0.0%. All patients were asymptomatic on their last follow-up with no definitive obstruction on imaging, and no requirement for additional procedures or stents. CONCLUSION: Single-port low anterolateral extraperitoneal pyeloplasty is a feasible alternative for surgical treatment of UPJO in adult and pediatric patients with improved recovery outcomes.

INTRODUCTION: Patients with proctocolectomy and ileal pouch-anal anastomosis (PC-IPAA) face unique challenges in managing prostate cancer due to their hostile abdomens and heightened small bowel mucosa radiosensitivity. In such cases, external beam radiation therapy (EBRT) is contraindicated, and while brachytherapy provides a safer option, its oncologic effectiveness is limited. The Single-Port Transvesical Robot-Assisted Radical Prostatectomy (SP TV-RARP) offers promise by avoiding the peritoneal cavity. Our study aims to evaluate its feasibility and outcomes in patients with PC-IPAA. METHODS: A retrospective evaluation was done on patients with PC-IPAA who had undergone SP TV-RARP from June 2020 to June 2023 at a high-volume center. Outcomes and clinicopathologic variables were analyzed. RESULTS: Eighteen patients underwent SP TV-RARP without experiencing any complications. The median hospital stay was 5.7 h, with 89% of cases discharged without opioids. Foley catheters were removed in an average of 5.5 days. Immediate urinary continence was seen in 39% of the patients, rising to 76 and 86% at 6- and 12-month follow-ups. Half of the cohort had non-organ confined disease on final pathology. Two patients with ISUP GG3 and GG4 exhibited detectable PSA post-surgery and required systemic therapy; both had SVI, multifocal ECE, and large cribriform pattern. Positive surgical margins were found in 44% of cases, mostly Gleason pattern 3, unifocal, and limited. After 11.1 months of follow-up, no pouch failure or additional BCR cases were found. CONCLUSION: Patients with PC-IPAA often exhibit aggressive prostate cancer features and may derive the greatest benefit from surgical interventions, particularly given that radiation therapy is contraindicated. SP TV-RARP is a safe option for this group, reducing the risk of bowel complications and promoting faster recovery.

OBJECTIVE: To evaluate the perioperative complications of single-port robot-assisted radical prostatectomy (SP-RARP). PATIENTS AND METHODS: A retrospective review was performed on the prospectively maintained, Institutional Review Board-approved, multi-institutional Single-Port Advanced Research Consortium (SPARC) database. A total of 1103 patients were identified who underwent three different approaches of SP-RARP between 2019 and 2022 using the purpose-built SP robotic platform. In addition to baseline clinical, perioperative outcomes, this study comprehensively analysed for any evidence of intraoperative complication, as well as postoperative complication and readmission within 90 days of the respective surgery. RESULTS: Of the 244, 712, and 147 patients who underwent transperitoneal, extraperitoneal, and transvesical SP-RARP, respectively, intraoperative complications were noted in five patients (0.4%), all of which occurred during the transperitoneal approach. Two patients had bowel serosal tears, two had posterior button-holing of the bladder necessitating repair, and one patient had an obturator nerve injury. Postoperative complications were noted in 143 patients (13%) with major complications (Clavien-Dindo Grade ≥III) only identified in 3.7% of the total cohort. The most common complications were lymphocele (3.9%), acute urinary retention (2%), and urinary tract infection (1.9%). The 90-day re-admission rate was 3.9%. CONCLUSION: The SP-RARP is a safe and effective procedure with low complication and readmission rates regardless of the approach. These results are comparable to current multi-port RARP literature.
RESUMEN
PURPOSE: To provide an update on the diverse, contemporary urological applications of the Hugo™ RAS system. METHODS: A comprehensive literature review was performed to identify studies that described the clinical applications of the Hugo™ RAS system in Urology. The Hugo™ RAS is a new multi-modular robotic platform created by Medtronic, which offered new innovations, including an open surgical console and individual modular and extendable robotic arms that come in their own movable platforms. Since obtaining regulatory approval in Europe in October 2021, the novel platform has been increasingly used in various urologic and gynecologic procedures. RESULTS: A total of 10 studies were included, which involved 176 patients who underwent varying urological procedures. These included radical and simple prostatectomy, partial nephrectomy, radical and simple nephrectomy, ureterolithotomy, ureteral reimplant, pyeloplasty, and adrenalectomy. The different docking configurations, operating room set-ups, and early perioperative outcomes were described for the respective procedure. CONCLUSION: Based on the existing literature, the Hugo™ RAS system can be safely and effectively utilized for various urological procedures. The novel technology provided additional value in enriching the repertoire of urological minimally invasive surgical options. Further research with larger cohort of patients will be required to better refine the operating techniques and understand the perioperative outcomes of the Hugo™ RAS, especially when compared to other robotic surgical platforms.

Introduction: Prostate cancer diagnosis and treatment is challenging in surgically complex patients. Radical prostatectomy can be performed without peritoneal entry using novel single-port (SP) transperineal (TP) and transvesical (TV) approaches. We sought to examine the outcomes of radical prostatectomy using novel TP and TV approaches in patients with extensive prior abdominal surgeries. Materials and Methods: From 2019 to 2023, 51 patients with extensive prior abdominal surgeries were identified who underwent TP (18) and SP TV (33) robotic radical prostatectomy. Indications included history of various surgeries with open laparotomy, including J-pouch reconstruction (22, 43%), active stoma (14, 27%), and open bowel resection (9, 18%). In all patients, 12/51 (24%) had a history of incisional hernia repair with mesh. A retrospective analysis was performed. Results: All cases were completed without open conversion, bowel injuries, or blood transfusions. Length of stay was 5.6 hours for TV and 22 hours for TP. No opioids were prescribed in 91% of TV vs 56% of TP. One intraoperative complication (ureteral injury) occurred in a patient undergoing the TP approach. Postoperative complications were noted in 14/51 (27%), including 10/18 (56%) TP vs 4/33 (12%) TV. High-grade complications (Clavien 3) occurred in three patients (6%, all TP). Pathologic staging showed pT3 in 26/51 (17 TV vs 9 TP), while the remainder were pT2. Biochemical recurrences were noted in four patients (8%, three TV and one TP). Immediate continence was noted in 30% of TV patients. Long-term continence after 12 months was 92% in TV and 67% in TP. Conclusions: In patients with extensive prior abdominal surgeries, radical prostatectomy is feasible using a TP or TV approach. No bowel injuries or open conversion were observed. The SP TV approach offers advantages of shorter hospital stay, shorter catheter duration, less opioid use, fewer complications, and improved continence recovery.

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.

INTRODUCTION: We aim to report our surgical technique, functional and radiological outcomes of single port (SP) extraperitoneal robotic pediatric pyeloplasty through a low anterior (3 cm) access using a da-Vinci single-port (SP) robotic surgical system in the pediatric population. MATERIAL AND METHODS: We present our initial series of 6 pediatric patients that underwent robotic SP extraperitoneal pyeloplasty between 2022 and 2023. Patient clinicopathologic variables and perioperative outcomes were collected prospectively. RESULTS: All cases of SP extraperitoneal pyeloplasty were completed without any intraoperative complications or conversion to an open, laparoscopic, or multi-port robotic pyeloplasty. Total operative times including cystoscopy ranged from 178 min to 240 min. All patients tolerated the surgery with minimal postsurgical pain and no narcotic requirement. No intraoperative or immediate postoperative complications were recorded in the cohort. There were no readmissions after discharge at a median follow-up of 12 months (6-18 months) in our series. CONCLUSIONS: Single port extraperitoneal pyeloplasty is a safe and feasible option for upper tract reconstruction in pediatric patients. All patients had complete resolution of symptoms and improvement of hydronephrosis on follow-up imaging.

OBJECTIVE: To identify the factors associated with a short time of return to continence. METHODS: We analyzed the first 110 SP TV RARP consecutive cases performed by one surgeon from 2020 to 2022. Continence was defined as zero to one safety pad. Two statistical analyses were done. First, patients were divided: group A (n = 62) included individuals who achieved continence within the initial week postcatheter removal; group B (n = 48) rest of the patients. Descriptive statistics were compared, followed by logistic regression for independent variables. Second, time to continence was analyzed as a continuous variable employing linear regression. The primary outcomes were the independent variables significantly associated with a short time to continence. RESULTS: All cases were completed successfully, without additional ports or conversions. Median urinary catheter duration and time to continence were 3 and 3.5days, respectively. Patients achieving continence within 1week significantly presented with fewer preoperative urinary tract symptoms, lower prostate-specific antigen levels, and had smaller specimen weights postoperatively. Multivariable logistic regression established low specimen weight as the sole significant factor (P = .04). Furthermore, linear regression demonstrated that alterations in independent variables accounted for 12.7% of the variance in time to continence (P = .62). CONCLUSION: The regionalization of surgery to the bladder employing a retropubic space-sparing extraperitoneal approach during SP TV RARP contributes to a fast return to continence. According to our model, the factors that significantly predict a shorter time to continence include lower preoperative International Prostate Symptom Score, prostate-specific antigen, and postoperative specimen weight.

BACKGROUND: Surgical management of large prostatic adenomas can be performed via open, endoscopic, or robotic approaches. A low-profile single-port (SP) robot was built to work in confined areas (ie, the bladder) and regionalize surgery. OBJECTIVE: To describe the novel SP transvesical (TV) robot-assisted simple prostatectomy (RASP) and report clinical outcomes. DESIGN, SETTING, AND PARTICIPANTS: SP TV RASP cases were performed in an academic hospital by two surgeons from 2019 to 2023. A total of 117 cases were performed, and data from patients with at least 12 mo of follow-up were analyzed. The inclusion criterion was severe obstructive urinary symptoms or catheter-dependent urinary retention due to large prostates with volume >80 ml. SURGICAL PROCEDURE: The procedure consisted of two main steps through a single 3-cm suprapubic incision: first, enucleation of the adenoma, and second, a 360° bladder mucosal flap reconstruction. No drains or continuous bladder irrigation was used routinely. MEASUREMENTS: Intraoperative parameters, pre- and postoperative uroflowmetry, and 1-yr clinical outcomes were assessed. We used descriptive statistics to analyze the data. RESULTS AND LIMITATIONS: All procedures were completed successfully without additional ports or conversions. The median console time and estimated blood loss were 107 min and 100 ml, respectively. Transfusion rate was 0%. Intraoperative complications included two suspected air emboli attributed to high insufflation pressures. There were no major postoperative complications. In total, 95.8% were discharged within the first 24 h, with a median length of stay and pain score of 5 h and 3/10, respectively. There was persistent improvement in the median International Prostate Symptom Score and flow rate after 1 yr. The median Sexual Score Inventory for Men score was 20 at 12 mo. Our study is limited by its retrospective nature and cohort size. CONCLUSIONS: SP TV RASP is a feasible alternative for the management of severe benign prostatic hyperplasia that promotes fast recovery and demonstrates 1-yr improvement in urinary function. PATIENT SUMMARY: Single-port transvesical robot-assisted simple prostatectomy is a minimally invasive alternative for the treatment of large benign prostatic growth. A single robotic arm goes through a small incision in the skin and bladder to extract the obstructive prostatic tissue. Afterward, reconstruction of the area is done to decrease bleeding and improve postoperative symptoms. We found that patients recover quickly and have excellent clinical results with a low risk of complications.

PURPOSE: To study the pathologic and short-term oncological and survival outcomes following Transvesical Single-Port Robot-Assisted Radical Prostatectomy. MATERIALS AND METHODS: A retrospective review was performed on prospectively collected data on 169 patients with low and intermediate-risks prostate cancer, who either underwent Single-Port Transvesical or Multi-Port Transperitoneal Radical Prostatectomy by a single surgeon between 2015 and 2022. Preoperative clinicopathologic characteristics, as well as final histopathology outcomes, were compared. Univariate Cox proportional hazard analysis was used to evaluate the impact of the surgical approach on biochemical recurrence-free survival within 12 months. RESULTS: Single-Port Transvesical and Multi-Port Transperitoneal Robotic Radical Prostatectomy were completed in 85 and 84 patients, respectively. Preoperative clinicopathologic features were similar between the 2 groups. In terms of histopathology outcomes, the 2 groups had identical final Gleason Grades, T stage, as well as the rates of adverse pathological features and positive surgical margins (Pâ¯=â¯>0.05). Despite the lower median number of nodes in the single-port cohort of 2 (0-5) compared to 6 (4-9) in the multi-port cohort (Pâ¯=â¯<0.001), there remained no statistically significant difference in the rates of lymph node invasion (Pâ¯=â¯0.08). At a median follow-up of 12 months, there were no differences in the biochemical recurrence-free survival rates among both groups (Pâ¯=â¯0.38). Univariate Cox proportional hazard analysis did not consider surgical approach to be an independent predictor of biochemical recurrence (HR 0.53, 95%CI 0.13-2.23, Pâ¯=â¯0.39). CONCLUSION: In well-selected patients, single-port transvesical robotic radical prostatectomy provided a similar short-term oncologic control as the multi-port approach with similar surgical margin status and 1-year biochemical recurrence rates.
RESUMEN
BACKGROUND AND OBJECTIVE: The introduction of the single-port (SP) robotic system has led to new approaches in robot-assisted radical prostatectomy (RARP), such as the transvesical (TV) approach, offering high rates of early urinary continence. While previous studies of SP TV RARP have identified perioperative factors influencing continence outcomes, the impact of anatomical factors remains unexplored. This study aims to assess magnetic resonance imaging (MRI)-based anatomical predictors of urinary continence after SP TV RARP. METHODS: A retrospective analysis of consecutive SP TV RARP cases (November 2020 to June 2023) with preoperative prostate MRI was performed. Two urogenital radiologists independently evaluated ten anatomical parameters to distinguish patients achieving urinary continence within 1 wk and 3 mo. Nonparametric methods estimated receiver operating characteristic curves (area under the curve [AUC]) and inter-reader agreement. KEY FINDINGS AND LIMITATIONS: In 120 cases, 40% achieved continence within 1 wk, rising to 71.7% by 3 mo. Membranous urethra length (MUL) alone was significantly associated with continence at 3 mo (AUC: 0.67, p = 0.003). At 1 wk, several parameters, including anteroposterior diameter of the prostate, coronal membranous urethra length, prostate volume, and transverse diameter of the prostate, showed promise in predicting continence. CONCLUSIONS AND CLINICAL IMPLICATIONS: A longer preoperative MUL was significantly associated with better odds of an early return to urinary continence after SP TV RARP. Each 1-mm increase in coronal MUL was associated with a 27% increase in the odds of continence at 3 mo. This information can aid in patient counseling and expectations preoperatively. PATIENT SUMMARY: Urinary incontinence is a common outcome after prostate cancer surgery, particularly in the early months. Recently, the single-port (SP) robotic system has emerged, localizing surgery to the diseased area. With the SP robot, accessing the prostate via the bladder leads to high rates of early continence. Our study reveals that the longer the urethral portion beneath the prostate, the higher the likelihood of regaining continence within 3 mo after surgery.
RESUMEN
OBJECTIVE: To determine the rate of outpatient cases and identify predictors for same-day discharge (SDD) after single-port transvesical enucleation of the prostate (STEP). METHODS: Retrospective analysis of all consecutive STEP cases performed at a single center by 3 surgeons from February 2019 to October 2023. The cohort was categorized into SDD cases (<8 hours until discharge) and inpatient cases. Group comparisons were made and logistic regression was used to identify predictors of SDD. RESULTS: A total of 152 STEP cases were performed successfully without additional ports or conversions. Fifty-two patients were pre-planned admissions, leaving 100 planned outpatient cases, of which 86% were discharged on the same day (median length of stay of 4.7 hours). Comparing the groups, inpatient cases were older, had higher Charlson Comorbidity Index (CCI) scores, higher estimated blood loss (EBL) during surgery, and more intraoperative complications than SDD patients. Univariate logistic regression identified age and CCI as the predictors associated with SDD after STEP. Notably, there were no major postoperative complications or readmissions in either group. CONCLUSION: In our 4-year experience with STEP, lower age and CCI score were significant predictors of SDD. The comprehensive evaluation criteria for discharge foster a safe recovery at home, coupled with a 0% rate of major postoperative complications and readmissions. These findings underscore the safety and efficacy of STEP, guiding patient counseling and surgeon expectations.
RESUMEN
Single-port (SP) robotic surgery is a relatively new technology that is expected to become available on the European market within a year. We investigated the current expectations of robotic surgery experts and opinion leaders practicing in Europe. A 17-item online questionnaire was sent to 120 participants identified as "experts" on the basis of their general contributions to the field of robotic surgery. Overall, 90 responses were registered, with a response rate of 75%. Italy (30%), France (15%), and the UK (12%) provided the most participants, who worked mainly in academic-either public (60%) or private (20%)-hospitals. Most respondents (79%) had no previous experience with "single site" surgery, and attendance at scientific meetings (79%) and perusal of the literature (65%) were the sources of SP knowledge most frequently reported. The perceived advantages of SP robotic surgery included lower invasiveness (61%), easier access to the retroperitoneal or extraperitoneal space (53%), better cosmetic results (44%), and lower postoperative pain (44%). The most "appealing" SP procedures were retroperitoneal partial nephrectomy via an anterior approach (43%) and transvesical simple prostatectomy (43%). Within the limitations of this type of analysis, our findings suggest high interest and a positive attitude towards SP technology overall. Patient summary: Technology for single-port (SP) robotic surgery, in which just one skin incision is made in the abdomen to perform the operation, will soon be available in Europe. We conducted a survey on SP surgery among European experts in urological robotic surgery. The results show that there is high interest in and a positive attitude to SP surgery. The SP approach could result in better cosmetic results and lower postoperative pain for patients.
RESUMEN
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.

OBJECTIVE: To determine the number of cases required to reach plateau performance. METHODS: We performed a single-surgeon review of the first 100 consecutive procedures. All procedures were performed using the da Vinci single-port robotic system between November 2020 and March 2022. Time was used as the measure of the learning curve (LC). Relevant surgical steps were considered separately for detailed analysis. Data were collected retrospectively and analyzed through the cumulative sum method and moving average graphing. A comparative analysis was done between subgroups of 20 consecutive cases for perioperative outcomes. RESULTS: All cases were completed successfully, without extra ports or conversion. The LC for prostate excision showed initial exponential improvement and reached plateau at case 28. Vesicourethral anastomosis time gradually shortened over time, with a clear inflection point at case 10. Total operative time rapidly improved and plateaued early to 213.0 minutes. Robot-docking and undocking, achieving hemostasis, wound closure, and intraoperative idle times were consistent throughout the series. Estimated blood loss decreased significantly after the first 20 cases (from median of 135.0-88.0 mL, P = .03). CONCLUSION: In our early experience, the LC for single-port transvesical robot-assisted radical prostatectomy suggests that performance improved after 10-30 cases in the hands of an experienced robotic surgeon.

OBJECTIVE: To evaluate for differences in the perioperative and early postoperative outcomes between three different contemporary approaches of robotic radical prostatectomy (RARP), namely Single-Port (SP) Transvesical (TV), SP Extraperitoneal (EP), and Multi-Port (MP) Transperitoneal (TP). METHODS: Retrospective review was performed on 865 consecutive patients with localized prostate cancer who underwent SP-TV, SP-EP, and MP-TP RARP. SP-TV and SP-EP RARP were performed using the purpose-built SP robotic platform. All procedures were performed by a single, experienced robotic surgeon. Demographics, perioperative, and early postoperative data were collected from the prospectively-maintained database. Statistical analysis was performed with descriptive statistics as presented. RESULTS: All SP cases were completed without any need for conversion or additional ports. When compared with MP-TP RARP, both SP-EP and SP-TV RARP were associated with significantly reduced length of stay (median, SP-TV 5.07 vs SP-EP 5.1 vs MP-TP 26.6 hours, P = <.05) and with most patients being discharged within 24 hours (SP-TV 92.3% vs SP-EP 84.6% vs MP-TP 30.4%, P = <.05). Postoperative analgesia requirements were significantly reduced following SP-TV RARP with 95% did not require opioid analgesia after discharge, as opposed to 77.6% and 12.1% of patients in the SP-EP and MP-TP RARP cohorts, respectively (P = <.05). Additionally, SP-TV RARP demonstrated the added benefit of a shorter Foley catheter duration of 4 days with an earlier return of urinary continence. CONCLUSION: The localization of RARP, as facilitated by the SP robotic platform, provided the opportunity for enhanced postoperative recovery resulting in decreased length of admission and postoperative pain, which allowed for increasing adoption of opioid-sparing outpatient prostatectomy.
RESUMEN
Objective: To describe the technical evolution and perioperative outcomes of vesicourethral anastomosis (VUA) in transvesical (TV) single-port robot-assisted radical prostatectomy (SP-RARP). Materials and Methods: A retrospective review was performed on 189 patients who underwent TV SP-RARP by a single surgeon using the purpose-built SP robotic platform. VUA was completed from within the bladder using two unidirectional V-loc sutures in a continuous, semicircular manner with greater emphasis posteriorly. The most recent 20 cases of TV SP-RARP were selected to evaluate the anastomosis technique and to compare the perioperative outcomes with the first 20 cases of TV SP-RARP performed at our institution. Demographic and clinical data were collected from the prospectively maintained database and statistical analysis was performed. Results: VUA was effectively completed in all cases using the aforementioned technique without any suture breaks, need for conversion, or evidence of intraoperative complication, including urine leak. Marked improvement in the learning curve was observed, which translated to significant reduction in the number of VUA sutures (median: 13 vs 15, p < 0.05) and faster anastomosis time (median: 19.1 vs 33.5 minutes, p < 0.05). The number of anastomotic sutures did not correlate with the prostatectomy specimen weight or volume, especially with both being significantly greater in the latest cases (median weight: 45.1 vs 37.6 g, p < 0.05; median volume: 40.9 vs 36.2 mL, p < 0.05). Postoperative outcomes were favorable with immediate continence achieved in 51.3% of our total cohort and with no patients demonstrating evidence of bladder neck contracture. Conclusion: We provided a detailed technical description of VUA in TV SP-RARP. The improved maneuverability of the SP robotic platform allowed for unique movements to facilitate suture placements from within the confined space of the bladder. The learning curve of a single surgeon was shown in our study, which resulted in notable reduction in the number of sutures, faster anastomosis time, and improved perioperative outcomes.

OBJECTIVE: To evaluate the risk of postoperative hernia following different approaches of single-port robot-assisted radical prostatectomy (SP-RARP). METHODS: A retrospective review was performed on patients who underwent SP-RARP between February 2019 and December 2022. Demographic and clinical information was collected from the multi-institutional, prospectively-maintained Single-Port Advanced Research Consortium (SPARC) database. Data were analyzed using IBM Statistical Packaging for Social Sciences (SPSS) version 29.0 with descriptive statistics as presented. RESULTS: A total of 1103 patients were identified, consisting of 244 (22.1%), 712 (64.6%), and 147 (13.3%) cases performed via transperitoneal, extraperitoneal (EP), and transvesical (TV) approaches, respectively. During a median follow-up time of 11 months (interquartile range 5.7-17.1 months), only two cases of incisional hernia were reported. Both cases occurred following transperitoneal SP-RARP with one patient requiring surgical repair. There remains no evidence of postoperative hernia following EP and TV SP-RARP at the completion of our review. CONCLUSION: SP-RARP was associated with low risk for postoperative hernia. The risk was lower following TV and EP SP-RARP where the peritoneum is preserved.
