[Potency problems in rectal surgery].

Erectile impotency has an anatomic cause in 90% of the patients. Psychic problems may understandably develop later on. Rectal surgery can induce neural, arterial, or combined neurovascular lesions. Isolated vascular lesions cover, according to our experience, between 30% and 40% of the cases. They can be treated by revascularisation with a good success-rate. Good apprehension of topographic anatomy of nerves and arteries might preserve erectile potency in many patients.

Reduced bladder capacity in patients receiving intravesical chemoprophylaxis with mitomycin C.

After complete resection of superficial bladder carcinoma (Tis-2, G1-3), 75 patients were treated prophylactically with either 20 or 30 mg mitomycin C. Six patients developed a substantial reduction in bladder capacity (less than 200 ml). In 2 patients radical cystectomy of an otherwise tumour-free fibrotic bladder was necessary. The results of long-term treatment (2 years) suggest that reduced bladder capacity correlates with the cumulative dosage of mitomycin C.

[Effects of Botulinum A Toxin on the periurethral striated sphincter of the neurogenic bladder. Preliminary study].

The goal of this study was to try to determine the effects of the Botulinum A Toxin on the spasticity of the rhabdosphincter in 9 men with spinal cord injury and detrusor-sphincter dyssynergia. The cystometrography, before and after the endoscopic injection of 100 units of Botulinum A Toxin, consisted of recording the bladder, urethral and rectal pressures with microtip transducers the anatomical position of which was radiographically controlled. The subjective and objective results of that study allow us to conclude that the Botulinum A Toxin has a place in the treatment of spinal injuries with detrusor-sphincter dyssynergia. Due to his blocking effect on the release of acetylcholine in the motor nerve endings, the Botulinum A Toxin suppresses or decreases the spasticity of the rhabdosphincter and improves voiding. Although its relatively short living action (2-3 months) may require renewed injections, it has the advantage to hold off a surgical treatment such as a sphincterotomy and to give the patient another chance to reach a balanced bladder function secondary to the postinjection changes of reflexes which may have taken place between the bladder and the rhabdosphincter and vice versa.

Extracorporeal shock wave lithotripsy as monotherapy of staghorn renal calculi: 3 years of experience.

From May 1985 to February 1988, 61 patients with renal staghorn calculi (41 with incomplete C4 and 20 with complete C5 lesions) underwent extracorporeal shock wave lithotripsy monotherapy. Of the patients 37 were treated without preoperative Double-J* stenting, while 24 underwent Double-J stenting before extracorporeal shock wave lithotripsy. Of the patients with incomplete staghorn calculi (C4) and a preoperative ureteral stent 85% were free of stones after 6 months in contrast to only 52.4% of those without a stent and 85.7% of those with infected C4 calculi who underwent preoperative stenting. Hospitalization decreased from 17.7 days in patients without a stent to 14.2 days after stenting, followed by the number of auxiliary procedures (nephrostomy, Zeiss loop and ureteroscopy) and postoperative complications. Complete staghorn calculi (C5) without a preoperative stent had the smallest success rate of stone elimination: only 43.7% of the patients were free of stones after 6 months with a rehospitalization rate of 62.5%. For incomplete staghorn renal calculi (C4) extracorporeal shock wave lithotripsy monotherapy with a preoperative Double-J stent is the noninvasive method that offers excellent stone elimination (85%), comparable to the results of percutaneous nephrolithotripsy (with or without complementary extracorporeal shock wave lithotripsy) and anatrophic nephrolithotomy.

Management of ureteral stones by extracorporeal shock wave lithotripsy. 3 years of experience.

From April 1985 to March 1987 181 patients with ureteral stones were treated by means of extracorporeal shock wave lithotripsy (ESWL). Management for proximal calculi changed from in situ ESWL treatment (group n = 27) or placement of a ureteral catheter below calculi (group II, n = 30) to retrograde stone manipulation into renal pelvis (group IV, n = 52) or ESWL treatment under intraoperative irrigation of saline in cases where repositioning failed (group III, n = 50). The best stone-free rate for upper ureteral stones was obtained in group IV with 96% after 6 weeks, presenting also the shortest hospital stay (4.2 days) and lowest quota of postoperative auxiliary procedures (2%). Stones, not being dislodged into renal pelvis (49%), could be treated successfully in 86% by irrigation with saline during ESWL (group III). The stone-free rate decreased in patients with in situ treatment (group I: 67%) or ureteral catheter placement (group II: 83%). Treatment of these stones increased the need of postoperative ancillary procedures to approximately 30%. For distal ureteral stones ESWL and preoperative Zeiss placement achieved a stone-free rate of 95%.

Radical prostatectomy in cases of prostatic carcinoma: the problem concerning erectile impotence.

It has become fashionable to perform radical prostatovesiculectomy for carcinoma of the prostate using the nerve-sparing method. In cases with a not too large prostate and a locally limited tumor, it is possible to preserve erectile potency. Our anatomic and radiologic preparation proved that postoperative impotence is not only due to lesions of the nerves but, almost as frequently, the consequence of obliterations of the vessels or a combination of both. If the lesion is purely arterial, revascularization surgery guarantees normal erections.

[The staghorn calculus: anatrophic nephrolithotomy versus percutaneous litholapxy and extracorporeal shockwave therapy versus extracorporeal shockwave lithotripsy monotherapy. A report of over 6 years' experience].

From 1982 to December 1987, 71 with incomplete (C4 by Rocco) and 37 with complete (C5 by Rocco) staghorn calculi underwent anatrophic nephrolithotomy (AN; n = 29), or combined percutaneous nephrostolithotomy and ESWL (PCNL + ESWL; n = 21), or ESWL monotherapy without or with preoperative JJ stenting (n = 37/21). The patients with incomplete staghorn calculi (C4) and preoperative ureteral stenting were free of stones after 6 months in 15 of 17 cases (88%), which is comparable to our results with AN (90%) and combined PCNL + ESWL (85%). ESWL without JJ stenting were free of stones in only 52%. The treatment of infected C4 calculi with JJ stenting was especially successful (92%). Complete staghorn calculi (C5) represented the best results after AN (78%) and combined PCNL + ESWL (75%), in contrast to ESWL without JJ stenting (44%). Four patients with C5 calculi were treated with ESWL and preoperative stenting, three of them were free of stones after 6 months. For incomplete staghorn calculi (C4), ESWL monotherapy with JJ stenting seems to be a justifiable noninvasive method which offers excellent results in stone elimination (88%), with lower costs than AN or PCNL + ESWL. More invasive procedures should be reserved for complete staghorn calculi.

[Continent ileum reservoir with anastomosis to the urethra].

We report our experience with the directly to the urethra anastomosed continent ileal reservoir. Our results suggest that the S-Pouch is superior to the proceeding suggested by Kock both from clinical and urodynamic view. Continence is to be expected at an anastomosis of this pouch with the bladder neck, whereas at an anastomosis with the posterior urethra occasional cases of nightly incontinence were registered. This always happened when the neurovascular bundle had not been preserved intraoperatively. If an ileal reservoir is installed metabolic acidosis has to be carefully avoided.

[The effect of aminoglutethimide on steroid synthesis of the adrenal gland and its use in prostate cancer].

Following the hypothesis of depressing adrenal androgens in patients with relapsed prostatic carcinoma using Aminoglutethimide (AG), we performed a prospective study during three years, beginning in 1983. Twenty orchiectomized men aged 61-83 (mean 77) with progressive prostate carcinoma stage D2 (T0-4 Nx M1) were included. They received 4 x 250 mg AG and 50 mg cortisone daily. Overall response, according to NPCP-criteria, was 30% after 3 months (1 patient with partial remission and 5 patients stable), and at the end of trial 1 patient (5%) remained stable and 7 (65%) had progression. Laboratory controls of adrenal androgens did not show any significant change of androstenedione and DHEA-S within 3 months, and there was even an average rise of testosterone from 1 to 2 nmol/l. AG seems to be only of small advantage in secondary treatment of advanced prostatic carcinoma. But it is possible that aromatase inhibitors could be useful in treating BPH because of their influence on peripheral oestrogens.

[Surgical possibilities in treatment of vascular-induced erectile impotence].

We are of the opinion that in most cases of erectile dysfunction morphological factors are involved. These have to be defined by means of adequate diagnostic procedures. When vascular disease is responsible it is necessary to distinguish between arterial, venous and arteriovenous conditions. Whereas arterial failure can often be corrected, the treatment of venous leakage is problematic, as the primary disease seems to affect the cavernous bodies directly.

[Extracorporeal shock wave lithotripsy (ESWL) in the treatment of bile duct stones].

Ten patients with common bile duct stones not removable by endoscopic measures after sphincterotomy were treated by extracorporeally generated shock waves. In 9 patients stones up to 30 mm in diameter were disintegrated. Two patients became free of stone fragments spontaneously within one day and in 7 patients the stone fragments were extracted endoscopically. No complications occurred. Extracorporal shock wave treatment represents a promising alternative to surgery in cases where common bile duct stones cannot be extracted endoscopically.

Morphological changes in canine kidneys following extra-corporeal shock wave treatment.

Extracorporal shock wave lithotripsy has rapidly become established world wide as a routine method for treatment of nephro- and ureterolithiasis. Although initial studies showed no tissue damaging effect by the shock waves, we found in an animal experiment using canine kidneys, the ESWL induced damage to the renal parenchyma is more marked than originally assumed. The damage is limited to the area that was focused on, and heals relatively rapidly by connective tissue encapsulation with final cicatrisation without any further residual effects being observed until now. This parenchymal damage is probably also the cause of the macrohaematuria that is always observed during therapy. The resulting tissue damage is not extensive enough to cause demonstrable reduction of function as measured by the usual methods (serum creatinine, creatinine clearance, isotopy renography, i/v-urography). The main clinical complication is the large subcapsular haematoma which, according to present knowledge, could well result from a lesion of the larger peripheral vessels. Damage to other organs such as subserous colonic and small bowel haematomata are to be expected although they do not lead to clinical symptoms.

Arterially originated erectile disturbances: surgical possibilities and their alternatives--some personal thoughts.

The arterially originated erectile disturbances are the most common form of impotence due to morphological reasons. The concepts of therapy range from the surgical revascularization, to the intracavernous self-injection of vasoactive substances and to the implantation of penis prostheses. The advantages and disadvantages are discussed and weighed against each other.

[Retroperitoneal lymphadenectomy in non-seminomatous stage I, IIa and IIb testicular tumors].

Between 1961 and 1985, 190 retroperitoneal lymph node dissections (RLND) have been performed in the Urological Clinic of the University Hospital of Zurich in patients with low stage (I, IIa, IIb) non seminomatous germ-cell testicular cancer. Indication, operative technic, complications (8,9%, dry ejaculation in 27%) and the results of the operation are pointed out (relapse rate in stage I: 10%, IIa: 35%, IIb: 59% without and 14% with adjuvant chemotherapy). The question is analysed if this primary surgical approach in this primary surgical approach in these stages, simultaneously a diagnostic and therapeutic procedure, is still indicated in the era of efficacious chemotherapy.
