[Transurethral incision in primary bladder neck obstruction].

Sixty-one patients presenting primary obstruction of the neck of the urinary bladder are subjected to transurethral operative intervention and postoperative follow-up study in the period 1986 through 1990. The indications for performing transurethral incision of the bladder neck are established on the basis of subjective complaints against the background of data from uroflowmetry, miction cystourethrography and endoscopic study of the lower urinary ways. The obtained results point to an improvement of the subjective complaints in 74 per cent of the cases. In 78 per cent of the patients peak urinary flow exceeds 15 ml/sec. Repeated transurethral incision is necessitated in 8.1 per cent, and transurethral resection in the postoperative period is done in twelve patients (19.6 per cent). Postoperative strictures of the urethra are discovered in 8 patients (13.1 per cent), and retrograde ejaculation is documented in three patients (8.5 per cent) over the maximum observation term of 64 months. Postoperative hospitalization is average 3.2 days (range 2.7 to 5.9 days).
