Abstract
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).
