Endoscopic resection as treatment of enuresis with posterior urethral valves.

25 boys with both nocturnal enuresis and diurnal urgency, underwent a transurethral resection of a posterior urethral valve. Seventeen patients were cured, two improved partially, two did not respond and four were lost to follow-up. The authors recommend a routine voiding cysto-urethrogram in the work-up of enuretic boys, especially when nocturnal enuresis goes with diurnal urgency.
