Management and Outcome of Ureteropelvic Junction Obstruction in Senegalese Children

Introduction: The ureteropelvic junction obstruction is a rare congenital malformation of the upper urinary tract. We report its management and outcome at Senegal’s main pediatric surgical department. Patients and Methods: We conducted a descriptive review of all patients managed in our pediatric surgical department at Albert Royer National Children’s Hospital Centre from January 1st, 2013 to December 31st, 2017. Results: Thirty patients were included in our study. The mean age was three years. Males were more affected (sex ratio of 2.75). The prenatal diagnosis was made in 23% of cases using prenatal ultrasonography. An abdominal mass was the circumstance of discovery in 36% of cases, and lumbar contact and renal sloshing were found in 66% of cases. There was no renal function impairment in 93% of cases. Urinary tract infection occurred in 50% of cases. Ultrasonography (100%) and urinary computed tomography (56%) were used to diagnose. A temporary nephrostomy was performed in 23% of cases, and as definitive treatment, an open Anderson-Hynes procedure was performed in 96% as a nephrectomy was made in a patient. Early postoperative complications were encountered in 56% of cases: urinary tract infection (36%), surgical site infection and anastomotic stenosis (6% both), and urinoma and textiloma (both in 3%). A patient died from sepsis. After a mean follow-up of 12 months, no additional complication was reported. Conclusion: Ureteropelvic junction obstruction was frequently diagnosed late, and its management carried unneglectable morbidity in our environment. A laparoscopic approach would be a solution to improve its outcome.
