We treated 23 patients with bladder neck sclerosis following treatment of prostatic adenoma by TUR (20 patients, 87%) and adenomectomy (3 patients, 14%). All patients entered a protocol for bilateral longitudinal bladder neck incision (cervicotomy) and injection of orgotein in the area of incision. Of these, 21 patients were evaluable; 18 (85%) had no recurrence, symptoms remained unchanged without ring in 2 (10%) and there was 1 (5%) recurrence. The results achieved by this simple technique combined with local antiinflammatory therapy make it the treatment of choice for this pathological condition.
