[First experiences with the incontinence operation Kaufman III (implantation of a silicongel prothesis covered with polyurethanfoam) (author's transl)].
For operative treatment of urinary incontinence after TUR of the prostate, radical prostatectomy and meningocele operation the silicongel prothesis described by Kaufman was implanted. By compression of the bulbus urethrae a sealing effect was achieved. The pressure of the detrusor opens the urethra enough to enable urination. Seven patients were operated. The results directly after the operations were: three very good, two good and two bad. We achieved very good results by implantation of the prothesis "large" -in the case of the two bad operative results we used the "medium" size prothesis. By filling these protheses with 5 ml liquid they proved to be leaky. One of these was operatively removed and replaced by the size "large". This patient later developed a urethra stricture in the implantation region with overflow bladder after having been continent. By internal urethrotomy this condition was restored; except for minor dripping after miction the patient was continent. The prothesis of a direct postoperative continent patient had to be filled. This led to and infection with the development of fistula. The prothesis had to be removed. A further patient who sat on a hard object developed a lesion of the prothesis with resulting incontinence. At least six months after the operations four patients remained continent and three incontinent.
