[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.

[Hydronephrosis of the right kidney caused by retrocaval course of the ureter (author's transl)].

The genesis, diagnosis, and therapy of the retrocaval course of the ureter are described with reference to one of the author's own cases. The clinical significance of this anomaly is due to the development of a hydronephrosis. This can be corrected surgically with preservation of the organ by division of the renal pelvis, repositioning, resection of the retrocavally running ureter, and oblique end-to-end anastomosis. An enquiry as to the incidence of this condition revealed 32 retrocaval ureters at 53 West German urology departments in five years.

Mercaptopropionylglycine: a progress in cystine stone therapy.

During a 4-year period 9 cases of severe recurrent cystine stones and cystinuria were treated with mercaptopropionylglycine. The oral long-term administration revealed the high effectiveness of the drug and resulted in no further stone formation. Mercaptopropionylglycine is free of side effects and more effective than D-penicillamine.

[New aspects in the treatment of oxalate lithiasis (author's transl)].

The causes of hypercalciuria and simple diagnostic criteria for the various forms of hypercalciuria are outlined. Indications, effectiveness, limitations, and side effects of cellulose phosphate are described. Emphasis is placed on the biochemical pathogenesis and classification of hyperoxaluria. The problems of measuring and controlling oxalate excretion in patients with hyperoxaluria and calcium oxalate stones are discussed. Succinimide offers a partly successful approach to the reduction of endogenous oxalate synthesis.

[Calcium and magnesium concentrations in "Healthy" and lithiasic human kidney (author's transl)].

Calcium and magnesium levels in the cortex, medulla, and papilla of human kidney from 32 so-called healthy patients and from eleven patients with calcium-oxalate lithiasis were determined by atom-absorption spectralphotometry. A positive calcium gradient with the highest calcium concentration in the papilla was found in all kidneys. Compared to the control group, that calcium concentration in the lithiasic kidneys was reduced by 50% in the papilla, but in the cortex and medulla, the levels were the same. A relative depletion of calcium in the papilla in hypercalciuria goes against the theory that the papilla is the main center of development of calcium-containing stones. The magnesium concentration was practically the same in cortex, medulla, and papilla, and no significant difference was found between lithiasic and healthy kidneys. These findings underline the central role of calcium in the genesis of calcium-containing stones.

[The effect of electrohydraulic waves and ultrasound on the urothelium].

An experimental study on 30 rabbit urinary bladders showed that the ultrasound lithotripsy causes less tissue damage and fewer complications than the use of electrohydraulic waves. The danger of perforation using electrolithotripsy is high whereas bladder wall perforations never were caused by ultrasound using the usual amplitudes and frequencies. An increase in temperature and edema formation in the bladder wall was caused by the ultrasound but this probably would be a minor damage in the clinical use.
