Double kidneys and renal fusions are the most common anomalies of the upper urinary tract. The effecting factors are still widely unknown. Very often these kidneys are the location and reason of recurrent infections, stone-forming and hydronephrosis. Operations like nephrotomies and partial resections, in which the preoperative knowledge of the arterial blood supply is of great help, have to be performed on them. In a series of 600 kidneys which were examined by pyelography and angiography we found among the 549 kidneys with a normal, single collecting system multiple renal arteries in 13,3% of the cases. In 27,5% of 51 double kidneys and renal fusions in this series we saw more than one artery, counting up to 4 arteries. A connection between the extent of renal duplication and the number of arteries could not be seen. Prior to parenchymal operations on double kidneys and renal fusions a renal arteriography should be performed, as multiple arteries and uncommon arterial origins are to be expected.

[Clinical experiences with lumboscopic kidney biopsy].

Lumboscopic renal biopsy is a new, quite convincing technique to gain renal tissue for histopathological and immunological examinations, which Sommerkamp introduced in 1974. A small flank incision (approx. 2 cm) is necessary to introduce a lumboscope into the retroperitoneal space. The lower pole of the kidney can be reached through the capsula adiposa and biopsy may be performed under view. The histopathological results and the postbioptic course in 55 patients show the advantages of this method against open surgical and percutaneous biopsy.

[Urinary retention caused by large cyst of the Müllerian duct (author's transl)].

The rare case of urinary retention caused by a large Müllerian duct cyst in a 41-year-old man is described. The embryological fundaments and frequency of these cysts are discussed as well as the necessary diagnostic steps and operative procedures. A survey of the literature is presented and the different diagnostic findings in these and other cystic tumors of the male pelvis are shown.
