Abstract

Purpose: Outcomes after laparoendoscopic single site pyeloplasty are limited to small cohort studies with short-term followup. We evaluated the clinical and renal function outcomes of what to our knowledge is the largest laparoendoscopic single site pyeloplasty cohort to date with a mean followup of 12 months. Materials and Methods: Consecutive patients diagnosed with symptomatic ureteropelvic junction obstruction who underwent robotic or conventional laparoendoscopic single site pyeloplasty were entered into the study. Patient demographics, and preoperative and postoperative renal function outcomes were recorded. Diuretic renogram was performed after stent removal, at 6 months and yearly thereafter. Results: The cohort included 31 conventional and 22 robotic laparoendoscopic single site pyeloplasties. Four laparoendoscopic single site surgeries (7.8%) were converted to another procedure due to failure to progress. Mean ± SD followup was 12.1 ± 10.7 months and 22 patients had at least 12 months of followup. No intraoperative complications occurred. Complications developed postoperatively in 11 patients (21%), of which 9 were Clavien grade 3 or greater. Preoperative symptoms resolved in 49 of 51 cases (96%). Severe obstruction (half-time greater than 20 minutes) was seen in 32 of 44 patients (73%) at presentation and obstruction resolved (half-time 20 minutes or less) in 41 (93%). Mean preoperative and postoperative half-time was 24.6 ± 13.4 and 8.3 ± 4.1 minutes, respectively, for an improvement of 16.3 ± 12.3 minutes (p <0.01). Conclusions: Laparoendoscopic single site pyeloplasty is safe and efficacious. The laparoscopic and robotic techniques provide excellent outcomes in terms of symptomatic relief and radiographic resolution of obstruction.
