Clean intermittent self-catheterization in the chronical management of the neurogenic bladder.

30 patients with neurogenic bladder dysfunction were treated with intermittent self-catheterization. Since the application of this method, urine loss has disappeared almost completely and the urinary infection rate has decreased. In some cases there was radiological improvement of the upper urinary tract. In all the other patients no kidney deterioration was found on intravenous pyelography. In most cases the method brought a real improvement in social life.

Antireflux in patients with neurogenic bladder.

The results of ureteral reimplantation in 8 neurogenic bladders with a high outflow resistance and severe trabeculation are presented. Operation was successful in all cases. The conditions for a successful intervention in these cases are: (1) previous or simultaneous treatment of the high outflow resistance: intermittent catheterization was found to be an excellent method for this purpose, and (2) the submucosal tunnel should be created preferably upon the trigone which is the only place free of trabeculation. High outflow resistance and severe trabeculation should no longer be considered as contraindications for antireflux surgery in the neurogenic bladder.

A plea for antireflux operations in adults: review of 50 cases.

The results of antireflux operations in 41 cases of primary and 9 cases of secondary vesicoureteral reflux in adults are presented. Reflux was eliminated in all cases and there were no postoperative complications. Most patients had a long history of urinary tract infection preoperatively, which was eliminated in 64.1 per cent of the cases after surgical correction of the reflux. A relapse of infection occurred in 30.8 per cent of these cases. Chronic pyelonephritis remains active in 5.1 per cent of the cases. There were 6 patients with serum creatinine levels higher than 1.8 mg. per cent who underwent a successful antireflux procedure without an increase of serum creatinine levels. An antireflux operation should be preferred over long-term conservative management in most cases of symptomatic vesicoureteral reflux in adults less than 50 years old.

Androgens in patients with benign prostatic hyperplasia before and after prostatectomy.

Plasma androgens [testosterone (T), 17beta-hydroxy-5alpha-androstan-3-one (DHT), androst-4-en-3,17 dione(A), and dehydroepiandrosterone (DHEA)] as well as 17 hydroxyprogesterone were measured in a group of patients (age 60-80 yrs.) with benign prostatic hyperplasia (BPH) just before prostatectomy and compared to values obtained in subjects of similar age without signs of BPH. The most important difference was observed in the mean DHT level which was significantly (P less than 0.025) higher than in the control group; mean T and free testosterone levels in BPH patients were slightly higher (P less than 0.05) in the age group 70-80 yrs; whereas in age group 60-70 mean values were similar to those observed in normal controls. Mean A, DHEA and 17 OHP and E2 levels were not significantly different in BPH patients when compared to age matched controls. 2-5 months after prostatectomy, T and DHT levels were significantly higher than immediately preoperatively. The preoperative stress may have influenced the preprostatectomy values.

Blunt ureteral trauma with perineal urine fistulization: review of the literature.

The first case of blunt ureteral disruption with external urine fistulization is presented. Reanastomosis with temporary urine diversion by a nephrostomy tube was successful. A review of the literature since 1950 revealed only 49 cases that proved this pathology should be considered in the differential diagnosis of post-traumatic hematuria or the development of mass in the flank. Nephrectomy is no longer used since a thorough attempt at reconstructive surgery will provide good functional results.

Preliminary clinical experience with meptazinol, a new analgesic.

The analgesic effect of intravenous meptazinol at various dosage levels was studied in 30 patients suffering from acute renal colic. Out of a total of 41 injections (dose range: 20 to 120 mg.) a favourable analgesic response was recorded on 39 occasions. The onset of action was rapid with the minimun duration of action of 1 hour. Higher doses increased the drug's action but were accompanied by nausea and dizziness. There was no overall effect on blood pressure or heart rate.
