Endopyelotomy. Evaluation of a limited experience.

Endopyelotomy is a recently developed endo-urological technique which gets to be standardised and gradually may replace the open pyeloplasty. Our technique is described and the early results are presented.

Use of transrectal longitudinal sonography in the placement of a prostatic coil.

Patients with acute or chronic urinary retention, not suitable for operation, no longer need permanent transurethral or suprapubic catheters. The prostatic coil is an excellent alternative. A series of 25 patients is presented. The technique of placement is described in detail as well as the use of longitudinal transrectal sonography in the preparation and follow-up of patients with a coil.

Fournier's gangrene. Report of three cases and review of the literature.

Fournier's gangrene, or synergistic gangrene of the male external genitalia is a rapidly spreading necrotising infection of the penis and scrotum. Although not so frequent in our civilized world it is by no means rare. In early days it was characterised by a high mortality. Aggressive surgical debridement, broad spectrum antibiotics and plastic reconstructive technics have all contributed to a better survival of the patients.

Syringocele, a rare lesion of Cowper's gland.

Syringocele are retentioncysts of Cowper's glands. First described by Fenwick, Maizels rediscovered them and made a very usefull classification. These cysts are more common than previously reported. They can be very obstructive for the urinary flow or cause no symptoms at all. Most are congenital. In our series we studied 5 patients with syringoceles. Treatment consisted in broad endoscopic unroofing. The results with this type of surgery are good. Follow-up showed all the patients to void well and to be free of other irritative symptoms.

Inverted papilloma of bladder: clinical significance.

Based on 15 cases of inverted urothelial papilloma, we present the clinical significance of these lesions in view of the current literature. An inverted papilloma should raise suspicion with respect to the whole urothelial surface. However, approaching every lesion of this type as a (pre-)neoplastic tumor does not seem justified, since 90 percent of all cases reported so far do not present any clinical or histologic feature of malignancy. Some factors, such as the patient's history, eventually associated urothelial carcinomas, or histologic features of malignant transformation within an inverted papilloma, must be taken into consideration. If no single indication in favor of malignancy has been disclosed, we believe follow-up with yearly endoscopic investigations, in addition to regular urine cytologies, may suffice.

[Pipemidic acid in the prevention of recurring cystitis in women].

The efficacy, safety and acceptability of pipemidic acid in the treatment and the prophylaxis of cystitis in women have been evaluated. After curative treatment, patients received prophylaxis using the compound for a duration of 6 months, and were followed up a further 4 month-period without specific therapy. During the prophylaxis period, no relapse was observed in over 85% of the treated patients. In 15% of cases, a pathogen reappeared along with recurrence of the preexisting symptoms. An increase to 29% of the cases was noted after the withdrawal of the treatment over a month study period. The pathogens involved in the cases of relapse during the prophylaxis period were sensitive to pipemidic acid in 1/3 of cases (6/18 cases), and resistant in 2/3 (12/18 cases) of cases. Those involved in relapses during the observation period were sensitive in 1/2 of the cases (8/16 cases), resistant or intermediate in 1/2 of the cases (8/16 cases). Thus, prophylactic treatment with pipemidic acid has a favorable influence on the number of relapses in patients with recurrent cystitis.

Treatment of chronic bacterial prostatitis by local injection of antibiotics into prostate.

Experiences with localized antibiotic treatment of chronic bacterial prostatitis by direct injection into the caudal prostate is presented. Very high antibiotic levels are found in the prostatic fluid without correlation with the time after injection. The pain and discomfort experienced by the patients during direct injection into the prostate are minimal. Hematuria and hemospermia during some weeks are practically always present after the injection. Local necrosis was not found after several histologic and electronic microscopic studies. Results demonstrated that this method deserves its place in the treatment of the hard-core group of chronic bacterial prostatitis.
