Artificial spermatocele persisting for 14 years.

In a patient with azoospermia secondary to bilateral agenesis of the vas deferens an artificial spermatocele was constructed from the tunica vaginalis testis. The sperm reservoir has been in place for 14 years with its size and the quality of the aspirated semen unchanged. A total of 70 aspirations performed during this period yielded mean volumes of 0.7 +/- 0.24 ml. with a sperm density of 60 +/- 14.7 million per ml. Sperm morphology was normal and sperm motility, although markedly decreased, responded well to stimulation by a motility enhancer. The patient did not have antisperm antibodies.

Results after organ-preserving surgery for renal cell carcinoma. An Austrian multicenter study.

Data from 120 patients diagnosed as having renal cell carcinoma (RCC), and treated in an organ-preserving surgical manner were analyzed from 11 participating Austrian urological centers. The male to female ratio was 66:54. The subjects age ranged from 27 to 75 years with mean age of 59 years. The indication for conservative tissue-saving surgery was a solitary kidney in 48 instances, a bilateral RCC in 18 cases and, in 2 patients, a horseshoe kidney tumor. In 52 cases the indication for conservative surgery was a peripheral, easily resectable, low-stage tumor (elective indication). Results were comparable to radical nephrectomy of low-stage tumors especially relating to survival rates. Ninety-nine patients survived and were tumor free at the point of check up (December 1988). Thirteen patients had either local tumor recurrence and/or metastases and 5 patients died from the disease. The operative mortality and the morbidity rate was very low.

[Urological complications following radical treatment of carcinoma of the cervix (author's transl)].

Urinary tract infection, obstruction and fistulation are the three commonest urological complications following radical treatment of cervical carcinoma. Special trends in treatment are discussed. Long-term results confirm the value of using a bladder flap in cases of reimplantation of the ureter into the bladder. Formation of a unilateral or bilateral "psoastip-bladder" (bipartition of the bladder) is described and active surgical management is recommended in cases of operable recurrent cervical carcinoma involving the urinary tract.

[Sulfametrol-trimethoprim in the treatment of chronic urinary tract infections].

Thirtyeight patients with a chronic urinary infection (definitions see methods) were treated for 3 months with Trimethoprim-Sulfametrol. During therapy in 19 (70%) out of 27 patients without obstruction in the urinary tract infection could be eliminated. In 3 (27%) out of 11 patients with obstruction in the urinary tract infection was also eliminated. In 2 (18%) of these 11 patients the causative organisms changed to resistant strains. In 2 patients (10%) resp. in one patient without obstruction and one with obstruction in the urinary tract the infection recurred within the follow up of 3 months.
