Bladder neck incision--a treatment for retention with overflow in the absence of adenoma.

Twenty-five cases of outlet obstruction with decompensated bladders and minimal adenomatous enlargement were treated by transurethral bladder neck incision. The results showed that bladder neck incision was as effective as transurethral resection of bladder neck and prostate and was a useful operation, especially for the elderly uraemic patient. There were no complications and operating time was considerably less than that required for a formal transurethral resection. The operation should be reserved for cases of outflow obstruction with no or minimal adenomatous hyperplasia.
