Abstract

Purpose

To assess the feasibility and outcomes of robotic pyeloplasty for complicated cases of ureteropelvic junction obstruction (UPJO).

Methods

Complicated UPJO cases included patients with the following: concomitant multiple or calyceal stones, secondary UPJO (post-ureteroscopy, open or percutaneous surgery), malrotated kidney, horseshoe kidney, ectopic kidney, giant hydronephrosis, poorly functioning kidney (glomerular filtration rate <20 ml/min), non-redundant renal calyces (requiring nephroplication), ptosis of the kidney (requiring nephropexy), long stricture (>2 cm), age <5 or >60 years and duplex pelvis. All cases underwent dismembered robotic pyeloplasty. Data were collected for operative time, blood loss, stone clearance, analgesic usage and time to recovery. Follow-up was done with intravenous urography and dynamic renal scan.

Results

A total of 29 cases underwent dismembered robotic pyeloplasty with an average operative time and blood loss of 130 min and 50 ml. Stone clearance could be achieved in 8 out of 10. The average follow-up period was 15 months with a symptomatic and objective success rate of 96.6% (28/29). No perioperative complications were noted.

Conclusions

Robotic pyeloplasty for complicated cases of UPJO is feasible, safe and effective, and has a durable success rate.
