Stricture prophylaxis in transurethral prostatectomy.

In a prospective study 317 patients with prostatic hypertrophy, admitted for transurethral prostatectomy (TUR P), were randomized into three different groups: (1) urethral dilation and TUR P; (2) urethrotomy according to Otis and TUR P, and (3) TUR P alone. The number of postoperative urethral strictures significantly decreased in the Otis group and significantly increased in the dilatation group as compared with the control group.
