[Catheter embolization of a bleeding inoperable hypernephroma].

The indications for and technique of transcatheter renal embolization are demonstrated in the light of a case of inoperable hypernephroma. The embolization was performed with autologous muscle tissue and involved no serious complications. The efficiency of the technique is evidenced by the resultant reduction in hematuria. An interesting aspect is the possible formation of a tumor abscess one month after the embolization.

[The treatment of prostatic adenoma].

Prostatic hyperplasia is a benign disease of elderly men. In 30-40% of the men the prostatic adenoma causes obstruction which requires operative treatment. 75% of these patients consult the general practitioner. Stage I is treated conservatively. Early surgery is indicated only in those undergoing surgery for hernia and in cases of intermittent obstruction. Operation is definitely indicated in stage II. Stage III should be treated initially with an indwelling catheter for 3-4 months. Treatment with lifelong indwelling catheter is rarely indicated today.

[Urinary continence after radical prostatectomy: the urodynamic proof of an anatomical hypothesis (author's transl)].

Prostatic carcinoma can be cured by a radical operation. In radical prostatectomy the whole so-called internal sphincter is removed. It is generally accepted and often proved that the external sphincter which is mostly somatically innervated cannot resume the funciton of continence. The postoperative urinary incontinence after radical prostatectomy is frequent and therefore the radical prostatectomy is not performed in many places. The problem of postoperative continence as well as incontinence after enucleation of the adenoma will be briefly discussed. In 1966, HUTCH described the so-called 'baseplate'. It is a bundle of smooth muscle fibers, circulary arranged around the bladder neck, which are also responsible for passive continence. He proposed that a certain sphincter function can be achieved by a tubular anastomosis of this anatomical substratum with the distal urethral stump. We were able to prove this anatomical hypothesis urodynamically. A specially constructed double-lumen perfusion catheter enabled us to register the so-called functional urethra profile and simultaneously register a new sphincter pressure wave in the transformed 'baseplate' which was responsible for the continence. We could observe this new sphincter region in all continent patients after radical prostatectomy whereas in the incontinent patients it was absent. Since 1972 we have employed the procedure proposed by HUTCH and have performed 20 radical prostatectomies. All these patients have been postoperatively completely continent. We are of the opinion that undue restraint concerning radical prostatectomy is no more justified.

[Late complications of the intestine after radiotherapy of bladder carcinoma].

Immediate reactions of the intestines during or after radiotherapy of the pelvis are very common. Later complications requiring surgical intervention are seldom found. Out of 101 patients with bladder carcinomas, we observed 4 with severe irreversible intestinal changes. These had been operated and had received post-operative radiotherapy. On 3 patients a sigmoid stenosis had to be resected under the protection of a colostomy. On the fourth patient an ileovesical fistula was closed primary.

[Bladder substitution with continent ileum pouch experimental study on dogs (author's transl)].

Ileum conduit is a good method for supravesical diversion of urine. The disadvantage is, however, that it does not have a reservoir function. For the first time, in 1969 Kock had shown good results with a continent intra-abdominal ileum pouch for feces, and this gave us the idea to try a similar pouch for urine on 15 dogs. To make reservoirs of the small intestine was technically not simple and often led to complications. Urine continency could be attained by invagination of the small intestine. Primary and secondary reflux as well as stenoses of the ureter implantations led in 50% of the cases to ascending infections. Complications of urine reabsorption did not occur. Further studies of the continency, reflux and reabsorption problems indicate that a continent, intra-abdominal ileum pouch for urine will be possible.

Continent ileal bladder: an experimental study in dogs.

A method for constructing a continent ileal bladder has been tested in dogs. The requirements for a continent ileal bladder: continence, reservoir function, prevention of reflux, could be fulfilled in our experimental study.
