[Fabian's spiral endoprostatic prosthesis].

This involves a supple metal prosthesis placed in the posterior urethra to relieve cervico-prostatic obstruction whilst allowing for normal function of the striate sphincter as well as satisfactory bladder drainage with normal continence. Easily inserted under local anesthesia and without morbidity, with a perfect functional result in the great majority of cases provided indications are complied with, i.e. essentially prostatic hypertrophy with retention. This prosthesis is designed for use in patients with temporary or permanent contraindications to surgery. Compliance with the very precise technique for insertion, under optical and televisual control, as well as with surgical contraindications (neurological bladder, cerebral arterial sclerosis, concomitant bladder lesion), ensures a good result. This prosthesis thus avoids the need for an indwelling catheter.
