STRICTURE OF THE PROSTATIC URETHRA FOLLOWING TUR-P

Abstract

After 350 transurethral resections of the benign prostatic hyperplasia, six post urethral stricture cases were studied. All post urethral stricture cases occured in small benign prostatic hyperplasia patients with resected tissue weight of less than 10g. The origin of the stricture was at the middle point between the bladder neck and verumontanum. When the bladder neck is cut deeply, the stricture may occur. It is suggested that the capsular group of prostatic arteries, which supply the anatomical true capsule and external gland, are injured by deep cutting at the bladder neck and that post urethral stricture may occur as a result of it. In order to avoid post urethral stricture after TUR-P, the resector should not cut the scar tissue deeply again.
