Laparoscopic Pyeloplasty for Ureteropelvic Junction Obstruction in an Incompletely Duplicated Collecting System in a Patient with a Horseshoe Kidney

Abstract

We present a case of UPJO associated with an incompletely duplicated collecting system in a horseshoe kidney that was successfully treated by laparoscopic pyeloplasty with concomitant pyelolithotomy. A 53-year-old man had three urological anomalies and urolithiasis. We performed a pyeloplasty and pyelolithotomy using a fully intracorporeal technique. Clinical and radiographic evaluation confirmed complete resolution of the patient’s condition. To our knowledge, there have been no reported cases of UPJO in an incompletely duplicated collecting system with a horseshoe kidney in the same patient. We also provide convincing evidence that laparoscopic pyeloplasty is feasible in complex cases of renal anatomic anomalies.
