Valve of the Posterior Urethra in Girls: A Case Report from the Gavardo Hospital in Mali

Abstract

This is a prospective study of a single case of posterior urethral valve in a 2-year-old girl in the Gabriel Toure Urology Department. Posterior urethral valves (PUV) are congenital obstructive membranous folds that represent the main cause of congenital subvesical obstruction and dysuria in children and infants [1]. Their aetiology remains unknown, and is probably related to poor positioning of the orifices of the Wolffian ducts leading into the urethra [2]. Abdominal and pelvic ultrasound combined with Uroscanner revealed bilateral ureterohydronephrosis with repercussions on the upper urinary tract. Suprapubic cystography showed stenosis of the membranous urethra with dilatation of the posterior urethra upstream of the valve and diverticular bladder. The procedure consisted of ureterovesical reimplantation plus intubation via an external ureteral drain, which was removed at10 postoperatively, and stripping followed by ureterovesical catheterisation. The post-operative course was straightforward.
