Urethral strictures following transurethral resection of posterior urethral valves.
Dense urethral strictures developed in 3 of 36 patients (8 per cent) following transurethral fulguration of posterior urethral valves. Common potential etiologies include the use of a loop resectoscope, large size of the valves and immediate supravesical diversion. The latter results in a "dry" urethra and the strictures that resulted may be analogous to the stenosis seen following a "dry" ureteral reimplant. Techniques to maintain flow through the urethra after resection and the avoidance of an extensive resection may be helpful in preventing urethral strictures.
