Early versus delayed internal urethrotomy for recurrent urethral stricture after urethroplasty in children.
BACKGROUND
Our aim was to evaluate the results of early versus delayed internal urethrotomy for management of recurrent urethral strictures after posterior urethroplasty in children.


METHODS
Twenty boys with proven posterior urethral strictures were treated by perineal posterior urethroplasty. Of these, 12 required internal urethrotomy. Each radiograph demonstrated a patent but irregular urethra with a decrease in diameter at the point of repair (fair results). Patients were then divided into 2 groups: 6 underwent early (within 6 weeks from urethroplasty), and 6 underwent delayed (after 12 weeks from urethroplasty), internal urethrotomy with the cold knife as a complementary treatment. The groups were comparable in terms of patient age, etiology of the primary urethral stricture, number of recurrences, length and site of the actual stricture, and preoperative maximum flow rate. Mean follow-up was 5 years.


RESULTS
Kaplan-Meier analyses showed that the stricture-free rate was 66.6% after early, and 33.3% after delayed, internal urethrotomy (P = .03).


CONCLUSIONS
Early internal urethrotomy should be considered in boys with recurrent urethral stricture after urethroplasty.
