Management of urethral valve obstruction in male neonates

Over the past 6 years, 18 neonates with a posterior urethral valve obstruction have been treated. The mortality has been markedly reduced by meticulous investigation, better medical management of renal failure, greater use of catheter drainage and simpler methods of valve ablation and reduction in the use of nephrostomy and ureterostomy. Mortality was 33%, but ther has been no mortality in the last 7 patients.
