Percutaneous nephropyelostomy has been performed on 24 patients. The method is simple, has few complications and can be performed rapidly; it can be recommended for both temporary and permanent supravesical urinary drainage. It represents an improvement in urologic techniques.

On the basis of 305 partial resections of the kidneys is reported on experiences with an own operation technique. By applying a chromium cat-gut supporting suture a secure and pboblem-free care of the resection wound is possible, which guarantees an as far as possible uncomplicated postoperative course. The operation technique is described and in general the problems of postoperative early and late complications are discussed.
It is reported on the occlusion of the renal artery with Spongostan in 25 cases of malignant renal tumours. The embolisation takes place immediately after the angiographic diagnosis of the renal tumour, in which case on account of the simplicity of the method every radiologist working in the field of angiography is able to perform the occlusion of the renal artery. It is not difficult to get embolisation material and it is available in nearly every surgical department. In 15 cases the later on performed extracapsular nephrectomy was, compared with the non-embolised kidneys, was facilitated by an edematous marginal zone and diminution and lacking filling of the tumour veins and on account of the smaller loss of blood led to a reduced operation stress of the patient. Apart from this on account of the missing blood supply of the kidney the ligature of the renal vein could be performed at an earlier moment of the operation and thus an intraoperatively haematogenic metastasation could be prevented. In 10 inoperable cases the embolisation was performed for the exclusion of haematuria and in order to stop and to decrease the further growth of the tumour. On account of the simplicity if the method, connected with the advantages resulting from this, the authors would like no more to miss this approach in future.

A new method for testing the function of the kidney after partial nephrectomy is reported. By means of radioisotope renography, urography and radioisotope clearance ('single-shot' method) it is possible to prove the function of the single kidney. The clearance in regard to the size of the shadow of the kidney assessed by urography allows to estimate the specified kidney function. We used these methods in ten patients and we detected that the loss of function is more extensive than expected by the operative reduction of the kidney parenchyma only. The causes for this are discussed.
