The outcomes of robot-assisted surgery in the treatment of neurogenic lower urinary tract dysfunctions: a systematic review and meta-analysis

AIMS

To assess the outcomes of robotic surgery for patients with neurogenic lower urinary tract dysfunctions (NLUTD).

MATERIALS AND METHODS

Studies evaluating the outcomes (efficacy and safety) of robot-assisted ileal conduit creation or artificial urinary sphincter (R-AUS) implantation or augmentation cystoplasty or continent urinary diversion creation in patients with NLUTD were included. The search strategy and studies selection were performed on Medline, Embase and Cochrane using the PICOS method according to the PRISMA statement (PROSPERO 2022 CRD42022333157). The comparator, if available, was the use of open or laparoscopic technique. Meta-analysis was performed whenever possible. The remaining articles were synthesized narratively.

RESULTS

Eight articles were included. Five described the outcomes of robot-assisted cystectomy with ileal conduit creation, two described the outcomes of augmentation cystoplasty and continent urinary diversion creation and one described R-AUS implantation in patients with NLUTD. The risk of bias was high. Three articles comparing the outcomes of robotic and open cystectomy and ileal conduit creation were suitable for meta-analysis. According to our meta-analysis, robot-assisted surgery had better outcomes compared to open surgery in terms of high-grade early postoperative complications (OR 0.39; 0.19-0.79; p = 0.01), days to bowel recovery (Cohen's D = - 0.62  ± 0.14, p < 0.001), length of hospitalisation (Cohen's D = - 0.28 ± 0.13; p = 0.03) and estimated blood loss (Cohen's D = - 1.17 ± 0.14, p < 0.001).Regarding AUS implantation, augmentation cystoplasty and continent urinary diversion creation, the outcomes from the articles included in our systematic review showed a 16-40% overall early complication rate in case of augmentation cystoplasty and 22% in case of AUS implantation.

CONCLUSIONS

Robot-assisted surgery may have several advantages over open surgery in the treatment of NLUTDs. However, current evidence is insufficient to draw firm conclusions. Further high-quality studies are needed to better understand the role of robotic surgery in the treatment of NLUTD.

Surgical Outcomes and Safety of Robotic Sacrocolpopexy in Women With Apical Pelvic Organ Prolapse

Purpose

This study aimed to investigate the surgical outcomes and safety of robotic sacrocolpopexy (RSC) in patients with uterine/vaginal vault prolapse.

Methods

Between January 2009 and June 2015, 16 women with apical prolapse underwent RSC. Pelvic organ prolapse quantification (POP-Q) examination was performed, and treatment success was defined as the presence of grade 0 or I apical prolapse upon POP-Q examination at the final follow-up. Pelvic floor distress inventory-short form 20 (PFDI-SF 20) was administered at every follow-up. A treatment satisfaction questionnaire was administered by telephone to evaluate patient satisfaction with the operation.

Results

Median age was 65 years (interquartile range [IQR], 56–68 years), and follow-up duration was 25.3 months (IQR, 5.4–34.0 months). Thirteen women (81.3%) had ≥grade III apical prolapse. Operation time was 251 minutes (IQR, 236–288 minutes), and blood loss was 75 mL (IQR, 50–150 mL). Median hospital stay was 4 days (IQR, 3–5 days). At the final follow-up, treatment success was reported in all patients, who presented grade 0 (n=8, 57.1%) and grade I (n=6, 42.9%) apical prolapse. Dramatic improvements in PFDI-SF 20 scores were noted after RSC (from 39 to 4; P=0.001). Most patients (12 of 13) were satisfied with RSC. An intraoperative complication (sacral venous plexus injury) was reported in 1 patient, and there was no conversion to open surgery. Mesh erosion was not reported.

Conclusions

RSC is an efficient and safe surgical option for apical prolapse repair. Most patients were satisfied with RSC. Thus, RSC might be one of the best treatment options for apical prolapse in women.
