Objectives:
To compare the perioperative and postoperative outcomes of single port (SP) robotic pyeloplasty and multiport (MP) robotic pyeloplasty using a propensity-score matched analysis.
Materials And Methods:
We performed a chart review of all patients who underwent SP robotic pyeloplasty from January 2019 to October 2020 and MP robotic pyeloplasty from January 2016 to October 2020. Patient demographics, intraoperative data, and postoperative outcomes were collected and analyzed. Propensity-score matching was performed on sex, body mass index, and history of previous pyeloplasty to adjust for potential baseline confounders. A post hoc sensitivity analysis for operative time was performed to examine the robustness of the results.
Results:
In total, 24 and 41 patients underwent sSP and MP robotic pyeloplasty, respectively. Following propensity-score matching, 21 MP cases were matched 1:1 to SP cases. The SP group was shown to have longer median operative times (128.0 vs 88.0 minutes, P = .0411) and shorter follow up time (9.3 vs 18.7 months, P = .0066). In a sensitivity analysis, SP robotic pyeloplasty was marginally associated with increased operative time (95% CI -0.25, 29.72, P = .0540).
Conclusions:
SP robotic pyeloplasty is a safe and acceptable alternative to MP robotic pyeloplasty, achieving comparable perioperative and postoperative outcomes.
