Internal Urethrotomy as a Complementary Method After Urethroplasties for Posterior Urethral Stenosis

Abstract

Failure of the treatment of posterior urethral stenosis ranges from 10 to 30 per cent. Strictures secondary to pull-through or transpubic urethroplasty are difficult to manage. The management of these strictures is reviewed in 21 children and 84 adults. Of the 105 patients 69 had been treated previously by a perineal pull-through technique and 36 by transpubic urethroplasty. A total of 18 patients (10 in the transpubic and 8 in the pull-through groups) whose results were fair or poor underwent internal urethrotomy with the Sachse knife as a complementary treatment after posterior urethroplasty. Internal urethrotomy provided good results in 8 patients (80 per cent) in the transpubic group and 5 (62.5 per cent) in the pull-through group. None of the patients was incontinent and there was no symptomatic urinary infection postoperatively.
