Laparoscopic primary ureterocalicostomy in children with ureteropelvic junction obstruction

Abstract

Introduction: Ureterocalicostomy (UC) involves excision of the hydronephrotic lower renal pole parenchyma and anastomosis of the dismembered ureter directly to the lower pole calyx. UC offers distinct advantages, notably for obstruction secondary to complicating anatomical anomalies of the kidney, such as horseshoe kidney. The present study was aimed to assess our experience and evaluate the outcome of primary laparoscopic UC in children with ureteropelvic junction obstruction (UPJO). Materials and Methods: We retrospectively reviewed the clinical notes, imaging records, and laboratory investigations of all the children who had undergone laparoscopic UC as a primary procedure in our center during a 12-year period (January 2006–December 2017). Results: Ten children (six males and four females) underwent laparoscopic primary UC for UPJO during the study period. The mean age of the children was 10.8 ± 2.78 years. The mean operating time was 175 min (range 140–210 min). No major intraoperative complications were noted. Conclusions: Primary laparoscopic UC for UPJO with complicated renal anatomy is feasible, safe, and associated with minimal morbidity. The outcomes show adequate drainage of the pelvicalyceal system.
