Posterior Urethral Valves in the Pediatric Surgery Unit of the Mali Hospital

Abstract

Posterior urethral valves (UPVs) are congenital obstructive membranous folds that represent the main cause of bilateral renal obstruction and dysuria in children and infants. The seriousness of this malformative uropathy lies in the importance of its impact on the upper urinary tract with a significant risk of end-stage renal failure. The objective of this work is to report our experience on the management of this pathology, for this we carried out a retrospective and descriptive study over a period of 5 years, from January 2018 to December 2022, including all hospitalized patients or seen in consultation at the pediatric surgery unit of Hôpital du Mal. The parameters studied were demographic, clinical, radiological and therapeutic variables. We collected 10 patients, an average of 2 patients per year and a frequency of 0.38%. The infant age group was the most represented, i.e. 80% of cases. The average age of our patients was 9.1 months with extremes of 2 days and 48 months. The most common reason for consultation was dysuria with 60% of cases. Overflow urination was the most frequent functional sign. Fever was present in 90% of cases. Abdominal distension was present in nearly half of our patients and acute urinary retention in 30% of cases. All our patients underwent cytobacteriological examination of urine. It was positive in 4 patients, i.e. 40% of cases. THE. Coli was the majority germ. All our patients performed retrograde urethrocystography (UCR) and objectified a dilation of the posterior urethra in all patients. Surgical treatment concerned all our patients. The FOGARTHY technique was used in 9 patients and a vesicostomy was performed in one patient. In the immediate therapeutic follow-up, 1 patient died in intensive care, 3 patients presented with sepsis, one of whom subsequently died. After an 8-month follow-up, the consequences are simple in all our patients.
