Role of urethral ischemia in the development of urethral strictures after cardiovascular surgery: a preliminary report.
A high incidence of urethral stricture was noted following cardiovascular surgery. In an attempt to elucidate factors predisposing to the occurrence of urethral stricture, we studied the penile blood flow in 7 patients presenting with strictures after cardiovascular surgery. Of these patients 5 had penile-brachial pressure indexes less than 0.5 and 6 had weak or absent erections. Of 14 patients studied prospectively by penile blood flow 2 had a low penile-brachial pressure index and suffered urethral strictures 6 weeks after cardiovascular surgery. This finding suggests that urethral ischemia could be a predisposing factor for the development of urethral strictures after cardiovascular surgery.
