Single-Port Mini-Pfannenstiel Robotic Pyeloplasty: Establishing a Non-Narcotic Pathway Along with A Same-Day Discharge Protocol

Single-port robot assisted partial nephrectomy via the supine anterior retroperitoneal approach (SARA)

This video explores the technique of robot-assisted partial nephrectomy using the Da-Vinci Single-Port robot via SARA in a 56-year-old male with history of diverticulitis found to have a 2.5 cm renal mass upon workup for abdominal pain. Retroperitoneal access was obtained at the McBurney point for port placement. Surgical steps: 1) retroperitoneal access at McBurney's point 2) renal hilum dissection 3) renal tumor identification 4) intraoperative ultrasound 5) hilar clamping 6) renal tumor excision using enucleoresection technique 7) Deep renorrhaphy 8) Early unclamping and cortical renorrhaphy. Surgery was successful without any complications with a warm ischemia time of 14 minutes.

Single-port robot-assisted pyeloplasty versus multiport pyeloplasty: evidence from controlled trials

This study evaluates and compares the results of single-port (SP-RAP) versus multi-port robot-assisted laparoscopic pyeloplasty (MP-RAP) for the treatment of ureteropelvic junction obstruction (UPJO). A systematic review and meta-analysis were conducted following PRISMA guidelines. Studies comparing SP-RAP and MP-RAP for UPJO treatment were identified from PubMed, Web of Science, and Cochrane Library databases. Key outcomes included operative time, hospital stay, and complication rates. Weighted mean differences (WMD) and risk ratios (RR) were calculated using fixed- or random-effects models based on heterogeneity. Statistical significance was set at P < 0.05. Both SP-RAP and MP-RAP demonstrated comparable surgical success rates (SP-RAP: 98.85%, MP-RAP: 98.08%), complication rates, and estimated blood loss. In the adult subgroup, SP-RAP was associated with shorter hospital stays (WMD: -0.52 days; P = 0.04). Postoperative morphine consumption was also lower in the SP-RAP group (WMD: -31.02 mg; P = 0.03), reflecting its minimally invasive nature. However, no significant differences were observed in operative time, pain scores, or renal function recovery between the two groups. Additionally, some studies suggested that SP-RAP may offer better cosmetic outcomes due to its single incision; however, due to the lack of standardized cosmetic satisfaction evaluation criteria, this finding is presented as a potential advantage rather than a definitive conclusion. The SP system demonstrates comparable safety and effectiveness to MP-RAP while offering advantages in cosmetic outcomes and recovery. Further long-term studies are needed to validate its benefits and optimize its application.

Single-port robot-assisted pyeloplasty through supine anterior retroperitoneal access

This video explores the technique of robot-assisted pyeloplasty using the Da-Vinci Single-Port robot through the supine anterior retroperitoneal access in a 28-year-old male with a right-sided ureteropelvic junction obstruction. The patient was placed in a supine position, with a 10°-20° elevation of the ipsilateral flank. Retroperitoneal access was obtained at the McBurney's point for the placement of the port. The standardized steps of the Anderson-Hynes pyeloplasty technique were executed. Operative time was 120 min with 10 mL of blood loss. The patient was discharged on the same day without complications. At 4-months follow-up, on the renal scan, the right kidney showed stable function with improved drainage.

Does Incision Location Matter? Analysis of Single-Port Cosmesis in Urologic Reconstructive Surgery

Introduction and Objective: One potential advantage of single-port (SP) robotic surgery compared with multiport (MP) robotic surgery is improved cosmesis. The only studies in urology patients to suggest this finding did not assess differences based on incision site. Our study evaluated SP, MP, incision location, age, gender, and prior abdominal surgery as predictors of cosmesis and scar consciousness for reconstructive procedures. Methods: This is a cohort study using an institutional review board-approved prospective genitourinary reconstruction database. Patients at least 3 months from surgery were emailed and called to complete the Consciousness subsection of the Patient Scar Assessment Questionnaire. Bothersome was defined as a score of 11 or greater. Overall consciousness was scored with a single item as "not conscious" or "conscious." Pearson's chi-squared, Wilcoxon rank sum, Fisher's exact test, and logistic regression were performed to assess how age, gender, prior surgery, and incision location affect cosmesis. Results: There were 111 patients (54 MP, 57 SP), of which 27 were SP umbilical, 14 were SP midline nonumbilical, and 16 were SP lower quadrant. On univariate analysis the periumbilical incision had the lowest consciousness. Age was associated with Bother (p = 0.012) and Consciousness (p = 0.002), whereas gender, prior abdominal surgery, and incision site were not significant. On logistic regression, all SP incisions were less likely to be bothered compared with MP, although only SP umbilical was statistically significant (odds ratio [OR] = 0.08, 95% confidence interval [CI]: 0.01,0.38; p = 0.005). Age was also significant on logistic regression for Bother (OR = 0.96, 95% CI: 0.93,0.99; p = 0.005). Gender and prior abdominal surgery were not associated with Bother or Consciousness. Conclusions: SP periumbilical incisions provide the best outcomes for cosmesis compared with other SP incision sites and MP incisions. This finding should be discussed and taken into account when planning surgical approaches for patients undergoing urinary reconstruction, especially in patients younger than 40 years of age.

Transperitoneal versus low anterior access single-port pyeloplasty: surgical and functional outcomes from a tertiary referral center

BACKGROUND

Transperitoneal approach to robot-assisted pyeloplasty (RAP) have been preferred in the last decades because of the use of multi-port robotic platforms. However, this approach is linked to notable issues, such as pneumoperitoneum and lateral decubitus position, which is associated with potential soft tissues injuries, and it is a time-consuming procedure. Single-port (SP) platform was introduced to potentially address these issues. Our aim was to describe perioperative surgical and functional outcomes of SP-RAP, including our preliminary results comparing the transperitoneal and LAA approaches.

METHODS

Data from a prospectively maintained dataset of all consecutive patients undergoing SP-RAP between 2019 and 2024 were retrospectively reviewed. Early procedures were performed using transperitoneal midline access, while later procedures utilized the low anterior access (LAA) approach. Patients' demographics, perioperative data, and surgical and functional outcomes were collected.

RESULTS

Overall, 34 patients underwent the procedure without intraoperative complications or conversion to an alternative approach. The median age was 46.5 (range: 35-56) years. The transperitoneal approach was used for the first 17 (50%) procedures, while the remaining 17 (50%) underwent LAA SP-RAP. Nonoperative room time, postoperative opioid dose, and length of hospital stay were significantly lower in the LAA group (P<0.001 in all cases), with all patients in the LAA group being discharged on the same day. No differences were observed in operative time or postoperative renal function.

CONCLUSIONS

Outcomes for SP pyeloplasties appear promising, and the LAA approach may help optimize operating room time, promote faster patient recovery, and reduce postoperative opioid use.

Single-port robotic extraperitoneal pediatric pyeloplasty using low anterior access: Description of technique and initial experience

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.

Low anterolateral incision for single-port extraperitoneal robot-assisted pyeloplasty: description of technique and initial experience

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.

Implementation of single-port robotic urologic surgery: experience at a large academic center

The Single-Port (SP) robotic system is increasingly being implemented in the United States, allowing for several minimally invasive urologic procedures to be performed. The present study aims to describe our single-center experience since the adoption of the SP platform. We retrospectively collected and analyzed consecutive SP cases performed at a major teaching hospital in the Midwest (Rush University Medical Center) from December 2020 to December 2023. Demographic variables were collected. Surgical and pathological outcomes were analyzed in the overall cohort and for each type of procedure. The study timeframe was divided into two periods to assess the evolution of SP technical features over time. In total, 160 procedures were performed, with robot-assisted radical prostatectomy (RARP) being the most common (49.4%). Overall, 54.4% of the procedures were extraperitoneal, with a significantly higher adoption of this approach in the second half of the study period (30% vs 74.3%, p < 0.001). A "plus one" assistant port was adopted in 38.1% of cases, with a shift towards a "pure" single-port surgery in the most recent procedures (21.1% vs 76.7%, p < 0.001). The median LOS was 33.5 h (30-48), with a rate of any grade and CD ≥ 3 postoperative complications of 9.4% and 2.5%, respectively, and a 30-day readmission rate of 1.9%. SP robotic surgery can be safely and effectively implemented for various urologic procedures. With increasing experience, the SP platform allows shifting away from transperitoneal procedures, potentially minimizing postoperative pain, and shortening hospital stay and postoperative recovery.

Clinical status and future prospects of single-incision robotic-assisted surgery: a review

Since the advent of conventional multiport laparoscopic surgery, the prosperity of minimally invasive surgery has been thriving on the advancement of endoscopic techniques. Cosmetic superiority, recovery benefits, and noninferior surgical outcomes weigh single-incision laparoscopic surgery as a promising modality. Although there are surgical challenges posed by steep learning curve and technological difficulties, such as instruments collision, triangulation loss and limited retraction, the establishment of robotic surgical platform as a solution to all is inspiring. Furthermore, with enhanced instrument maneuverability and stability, robotic ergonomic innovations adopt the advantages of single-incision laparoscopic surgery and surmount its recognized barriers by introducing a novel combination, single-incision robotic-assisted surgery. As was gradually diffused in general surgery and other specialties, single-incision robotic-assisted surgery manifests privileges in noninferior clinical outcomes an satisfactory cosmetic effect among strictly selected patients, and has the potential of a preferable surgical option for minimally invasive surgery.

Single Port Robotic Pyeloplasty: early single-center experience

PURPOSE

Ureteropelvic junction obstruction (UPJO) is a prevalent cause of hydronephrosis, especially in young patients. The treatment paradigm for this condition has shifted from open to minimally invasive pyeloplasty. In the present study we describe our initial single centre experience with single port (SP) robot-assisted pyeloplasty (RAP) via periumbilical incision.

MATERIAL AND METHODS

With the patient in a 60-degree left flank position, the SP system is docked with the Access port (Intuitive Surgical, Sunnyvale, CA, US) placed in a periumbilical 3 cm incision. Robotic instruments are deployed as follows: camera at 12 o'clock, bipolar grasper at 9 o'clock, scissors at 3 o'clock and Cadiere at 6 o'clock. After isolation and identification of the ureter and the ureteropelvic junction (UPJ), the ureter is transected at this level and then spatulated. Anastomosis is carried out by two hemicontinuous running sutures, over a JJ stent.

RESULTS

Between 2021 and 2023, a total of 8 SP RAP have been performed at our institution, with a median (interquartile range, IQR) of 23 years (20.5-36.5). Intraoperative outcomes showed a median (IQR) OT of 210.5 minutes (190-240.5) and a median (IQR) estimated blood loss (EBL) of 50 mL (22.5-50). No postoperative complications were encountered, with a median (IQR) length of stay (LOS) of 31 hours (28.5-34).

CONCLUSION

In the present study we evaluated the feasibility and safety of SP RAP. The observed outcomes and potential benefits, combined with the adaptability of the SP platform, hold promising implications for the application of SP system in pyeloplasty treatment.

Single-Port Robotic Applications in Urology

Objective: The da Vinci single-port (SP) platform represents the latest innovation in minimally invasive urologic surgery, and the adoption of this technology by urologists is increasing. In this article, we briefly describe the evolution of minimally invasive and single-site surgery, and offer a comprehensive review of the current literature on the SP platform. Materials and Methods: For relevant articles, three electronic databases, including PubMed, Scopus, and Web of Science, were searched from their inception until August 15, 2022. The published literature to date within SP robotic surgery in urology will be discussed. Evidence Synthesis: There are relatively few high-quality studies on the SP system, but there are multiple case series describing unique indications and surgical approaches with the SP robot, demonstrating safety and feasibility in the hands of experienced robotic surgeons. There also are an increasing number of prospective, larger cohort studies comparing outcomes between SP and multiport (MP) approaches that show benefits of the SP system regarding improved cosmesis, postoperative pain control, and decreased length of stay. Conclusions: Multiple prospective studies have shown benefits regarding cost and pain control for SP platform procedures compared to the traditional MP robotic approach. While its high cost and learning curve represent barriers to adoption, the SP platform represents a critical development in minimally invasive surgery. As this technology is further implemented at more institutions, long-term, high-quality data should accrue that will demonstrate its true value.

Single-Port vs Multiple-Port Robot-Assisted Laparoscopic Pyeloplasty for the Treatment of Ureteropelvic Junction Obstruction: A Systematic Review and Meta-Analysis

Background: Single-port robot-assisted pyeloplasty (SP-RP) has been performed in recent years. However, the advantages and disadvantages of SP-RP compared with multiple-port robot-assisted pyeloplasty (MP-RP) remain unclear. The purpose of this meta-analysis was to compare the safety and feasibility of the two technologies. Materials and Methods: Through a literature search using MEDLINE, EMBASE, and the Cochrane Library, studies comparing SP-RP and MP-RP were identified for meta-analysis. Comparisons of perioperative and postoperative outcomes between the groups were analyzed using weighted mean difference (WMD) and risk ratio. Results: Five retrospective cohort studies with 179 patients were included in this meta-analysis. The results showed that SP-RP was associated with shorter hospital stay (WMD: -0.6 minutes, 95% confidence interval [CI]: -1.19 to -0.02, p = 0.04), less postoperative pain (pain score, WMD: -0.84, 95% CI: -1.62 to -0.07, p = 0.03), and superior cosmetic appearance compared with MP-RP. In addition, no differences were found between the SP-RP and MP-RP groups in terms of operative time, blood loss, rate of complications, and recovery of renal function. Conclusion: SP-RP provided comparable effectiveness, safety, and superior outcomes in terms of cosmetic appearance and pain compared with MP-RP, which gives surgeons the confidence to adopt and promote these ultraminimal invasive surgeries.

Upper Urinary Tract Surgery Through Robotic Single-Port System Vs Multiport and Laparoendoscopic Single-Site Systems: A Systematic Review and Meta-Analysis

Purpose: We aimed to make a general comparison between the safety and feasibility of a novel robotic platform, da Vinci^® single-port (SP) system with conventional robotic multiport (MP) and laparoendoscopic single-site systems (da Vinci Xi or Si) in three upper urinary tract procedures including robot-assisted partial nephrectomy (RAPN), robot-assisted pyeloplasty (RAP), and robot-assisted adrenalectomy (RA). Materials and Methods: After systematical searching of the literature up to October 2022 in PubMed^®, Web of Science™, and the Cochrane Library and Scopus^® databases, we extracted and processed the data in eligible literature for operative time, warm ischemia time (WIT), morphine milligram equivalent (MME), postoperative complications, and positive surgical margins (PSMs). Results: A total of 752 patients who underwent robotic surgery for SP or MP from 11 articles were included in this meta-analysis. There was no statistically significant difference in operative time for either RAPN (standardized mean difference [SMD] -0.14, 95% confidence interval [CI] -0.30 to 0.03) or RA (SMD -0.51, 95% CI -1.08 to 0.06). However, for RAP, SP can save operation time (SMD -0.73, 95% CI -1.24 to -0.22). The introduction of SP did not increase complications to any degree, including total complication (risk ratio [RR] 0.89, 95% CI 0.52-1.53), minor complication (RR 0.43, 95% CI 0.13-1.36), and major complication (RR 0.85, 95% CI 0.34-2.09), nor the incidence of PSMs (RR 1.04, 95% CI 0.54-1.99). It is worth noting that although the SP system increased WIT (SMD 0.44, 95% CI 0.26-0.62), it had the benefit of reducing intraoperative pain for RAPN with regard of MME (SMD -0.40, 95% CI -0.71 to -0.09). Conclusions: In terms of postoperative pain, SP robotic surgery is beneficial for RAPN but will make WIT prolonged. RAP is probably the most suitable upper urinary tract procedure for which SP is an option, which helps to shorten the surgery time and achieve a minimally invasive wound at the same time. Our study has been registered in PROSPERO (Registration No.: CRD42022350317).
