The role of vesicostomy in the management of anterior urethral valves in neonates and infants.

We performed vesicostomy as the initial form of management in 2 male newborns and 1 infant with anterior urethral valves associated with proximal urethral diverticula and bilateral hydronephrosis. Prompt improvement in the degree of hydronephrosis was noted after vesicostomy in all 3 patients along with improvement in renal function in 2 who had presented with renal insufficiency. Subsequently, 2 patients have undergone vesicostomy closure and transurethral valve fulguration, and 1 also required ureteral reimplantation for persistent vesicoureteral reflux. The use of vesicostomy in the newborn period rather than transurethral fulguration prevented the potential complications of urethral stricture and inadequate valve resection that can occur owing to the small size of the neonatal urethra. Furthermore, a period of vesicostomy drainage before eventual ureteral reimplantation for severe vesicoureteral reflux obviated the need for ureteral tailoring.
