In 84 patients after nephrectomy due to renal cell carcinoma a computerized tomography was performed to evaluate local tumor recurrence. The findings are classified stage-dependent. Other metastatic lesions were found by conventional radiologic methods. Based on stage-dependent different occurrence of metastases or local recurrences recommendations are made to the use of computerized tomography in the follow-up of patients suffering from renal cell carcinoma after nephrectomy.

In 53 patients suffering from testicular cancer it was reviewed whether the changes of spermatogenesis due to radiation or chemotherapy are reflected by the sexual hormones (FSH, LH, T). After both therapeutic measures a reduction of the number of spermatic cells and volume of sperm was demonstrated. The reduction of spermatic cells was followed by a simultaneous increase of FSH and LH levels, whereas the testosterone level did remain normal.

In this study a new trocar-cannula-unit(10 French) is introduced, which was used in a prospective randomised comparative study in 74 patients for suprapubic bladder punction. Another 75 patients served as controls receiving a suprapubic punction with the standard Cystofix (French 10)-system. In the control-group 9 cases (12%) of macrohematuria occurred. On the other hand we found that the incidence of macrohematuria was reduced to 5 cases (6.8%), when using the new trocar-cannula-unit, which had been developed in our hospitals.

It is reported on the classification, pathophysiology and clinical relevance of obstructive nephropathy in the case of obstructive urinary transport disorders of the upper urinary tract. Despite successful experimental models a clinical indicator of reversibility of obstructive lesions may fail.

The currently high letality rate of uroseptic shock may be reduced by early recognition of symptoms and adequate therapy with elimination of causes. Decisive for the septic shock are initial disturbances of the microcirculation in the presence of hyperdynamic circulatory regulation with following disorders of the coagulation system, tissue metabolism, acid-base-balance and heart contractility. In the therapeutic armament the important role of vasoactive substances is stressed. In an analysis of 59 patients suffering from urosepsis the intrinsic and iatrogenic causes, the bacterial spectrum and the emergency operative interventions are evaluated, whereas a letality rate of nearly 12% and an injury grade of 34% are estimated.

The term "hypospadia feminis" means a congenital false urethral opening in the anterior vaginal wall proximal to the hymenal ring. In comparison to the male hypospadia it is a rare event. Obligatory an obstructive uropathy is found, but the pathophysiology remain obscure.

From 1986 to 1989 papaverine was used alone or in combination with phentolamine in 165 patients in diagnosis and treatment of erectile dysfunction. In 14 patients a prolonged erection did occur after diagnostical introduction of SKAT therapy. Treatment consisted of intracavernous injection of 2-4 mg metaraminol, partly additional by puncture of cavernous bodies and evacuation of viscous blood. As single complication of metaraminol injection a hypertensive crisis could observed. A glando-cavernous shunt was not necessary in any case. After exact dosage adjustment the danger of drug-induced priapism is low.

In a prospective randomized trial the anti-thrombotic effect of dipyridamole was studied in 64 patients after cadaveric kidney allotransplantation. The frequency of early graft function was significantly higher in the control group, whereas the incidence of arterial and venous thromboses were not different. One-year graft survival could not be improved by dipyridamole. Therefore, dipyridamole should not be recommended in cadaveric kidney allotransplantation.
