[BCG vs interferon A for prevention of recurrence of superficial bladder cancer. A prospective randomized study].

A total of 78 patients with superficial bladder carcinoma were prospectively randomized to two groups following complete transurethral resection (TUR). Each received 12 intravesical instillations of 10(7) units interferon A or 120 mg BCG Connaught for 1 year starting 6 weeks post-TUR. After a mean observation period of 24 (13-31) months in the BCG and 25 (6-32) months in the IFN group 5/32 (15.6%) recurrences in the BCG versus 21/35 (60%) in the IFN group were observed (P = 0.0003). In the IFN group 18.4% of the patients had dysuria and 2.6% fever; in the BCG group 35% had fever, 60% cystitis, 1 patient granulomatous epididimoorchitis and 1 patient pneumonitis with granulomatous prostatitis. With our instillation regimen interferon A had few side effects but also no prophylactic effect, whereas BCG had tolerable-seldom severe--side effects and was very effective in preventing recurrences. Perhaps IFN should be given earlier after TUR and in a higher dosage.

[Xanthogranulomatous pyelonephritis].

An 11-year-old boy suffered from malaise, weight loss and pallor. A palpable abdominal tumor on the right side, anemia and increased C-reactive protein were detected. Intravenous urography revealed destruction of the right kidney resembling Wilms tumor. But ultrasound and computered tomography rised skepticism. Analysis of previously documented cases suggests that xanthogranulomatous pyelonephritis must equally be considered in a child with unilaterally enlarged kidney without function, especially when the child shows fever, leukocytosis, bacteriuria, anemia, leukocyturia, calculi of the urinary tract, abdominal pain and/or a palpable abdominal tumor. Ultrasound and computered tomography can lead to the diagnosis, and identify extrarenal infiltration. Nephrectomy results in complete cure and is therefore the treatment of choice.

[Epidermoid cyst of the testis].

This is report of a group of four patients with epidermoid cysts of the testis. The pathogenesis, symptomatology, pathology and therapy of this benign testicular tumor (or tumor like testicular lesion) in these cases, including 150 reported cases in the literature are presented and discussed.

Can a substitute for the bladder sphincter be attained by free transplants derived from vesical muscle tissue?

Smooth muscle transplants of the intestinal tract have been tested experimentally as a substitute for the bladder sphincter. An attempt was made to apply the proposed technique to the vesical muscle tissue and to achieve a sphincter replacement with freely transplanted autologous bladder tissue. An internal urethrotomy was performed several times in female sheep until a complete urinary incontinence resulted. For the bladder sphincter substitute a strip of vesical tissue was dissected from the anterior wall and following pre-stretching it was sewed circumferentially around the urethra in order to constrict it. The urethral pressure was registered during the operation before and after application of the sphincter 'graft'. For temporary urinary discharge a suprapubic catheter was inserted. The sheep were examined clinically and urodynamically for up to 3 months. Complete urinary continence was not obtained in any of the cases. The urodynamic examination showed a nearly complete loss of the urethral pressure which had been obtained by the operation. The histological studies showed progressing fibrosis of the desired continence zone. By way of freely transplanted autologous vesical muscle a sphincter substitute could not be achieved.

[The results of combined treatment for testicular tumours. Report of 12 cases (author's transl)].

Over a ten year period, the authors have collected 120 cases of germinal tumours of the testis (35 seminomas and 85 non-seminomatous tumours). The largest single group was of mixed non-seminomatous tumours. The treatment of pure seminomas gave 100% good results by a combination of unilateral orchidectomy, radiotherapy and, in the case of stage III tumours with spread, chemotherapy. The prognosis of non-seminomatous tumours was dependent essentially upon the stage of spread. During the past three years, the best results of chemotherapy have been obtained with the combination of vincristin, bleomycin and platinum (1978, 1979, 1980). In his time, at stage I and stage II, all the patients are alive. Treatment consisted of a minimum of unilateral orchidectomy and retroperitoneal lymphadenectomy, Chemotherapy was envisaged only for those tumours with evidence of lymph node involvement. At stage III, they lost 3 patients out of 7, this being an excellent result bearing in mind the gravity of such tumours.
