[The bladder neck stenosis following prostatectomy. The various types and their treatment].

Twenty patients with contracture of the vesical neck following prostatectomy and with Marion's disease were successfully treated with Y-V plastic operation and posterior wedge excision. One patient had to remain in cystotomy catheterization because it was not possible at operation to detach the wall of the bladder from the os pubis. Five of eight patients were treated successfully by transurethral resection. The remaining three patients developed a recurrent contracture and underwent Y-V plastic operation. A stenosis at the site of anastomosis following radical retropubic prostatectomy may sometimes be managed by a Y-V operation using a simple retropubic approach. This was the procedure in one case. However, when the stenosis lies too deep in relation to the os pubis, one can always gain access via a pubectomy. Chiefly, contracture of the vesical cervix postprostatectomy is discussed, as well as the degree of obstruction, the characteristic symptoms, and the risks associated with wrong diagnosis. A new theory on the etiology is briefly described.
