[Recurrence prevention of papillomas of the bladder using lycurim instillation]. / Rezidivprophylaxe von Papillomen der Harnblase mittels Lycurim-Instillation.

Following surgical removal of papillary tumours of the bladder from 60 patients the authors performed short instillations of the bladder with LYCURIM. The histological picture revealed tumours in the stage O-A-B1 and grade I-II-III. In a control group (n = 129) 89 recidive cases were observed in 2 years. Out of the 60 patients of the LYCURIM group 19 (31.7%) were free of tumours for 2 years and 43 (71.7%) for 11/2 years. A transient cystitis which occurred with short application of the medicament was easily cured. Toxic effects on the blood picture were not observed.

The angiographic appearance of renal angiomyolipoma and problems of its preoperative diagnosis.

The radiodiagnostic difficulties of renal hamartoma (renal angiomyolipoma) have been discussed in connection with the authors' two cases. In the first case a unifocal cystic renal angiomyolipoma without tuberous sclerosis caused retroperitoneal haematoma and acute symptoms. In the second case a preoperative tentative diagnosis of angiomyolipoma was made, however, the Pringle-type dermal lesions were only observed 6 months after surgery on control examination. The authors state that the radiographic functional findings vary depending on the tissue structure of the tumour. Differential diagnosis of cystic angiomyolipoma containing little fatty and angiomatous tissue is impossible, whereas for the hypervascular variant a tentative diagnosis can be established even in the case of unifocal hamartoma.
