[Experiences with transparenchymal coral calculi removal under local hypothermia].

Under certain conditions genuine coral calculi are an absolute offication for nephrotomy. In order to achieve complete hygienization of the cavity ischaemia times of more than 25-30 min are often necessary. Controlled surface cooling proved to be very good for improving ischaemia tolerance and reducing post-ischaemic loss of function in 21 necessary nephrotomies out of a total of 651 operations for concrements in the calyx system of the renal pelvis (= 3.2%; = 32.8% of all nephrotomies). A kidney thermometer with a temperature feeler developed by us allows fine control of the hypothermia induced by means of plastic bags filled with ice crystals. The technique of operation together with its advantages and disadvantages are described.

[Behavior of the mucosa of the large intestine following definite urinary diversion].

Multiple biopsies of the mucous and submucous membranes were taken from 50 patients with definitive diversion of urine using the large intestine and evaluated. The varying behaviour of the membranes in connection with uretero- sigmoidostomies , cysto- sigmoidostomies and rectal bladders is discussed. The reactions of the mucous membrane in connection with uretero-intestinal anastomosis are time-dependent. The most serious changes in the mucous membrane occurred in connection with rectal bladders.

[Modification of the internal milieu by drainage disorders following urinary diversion].

On the basis of follow-up examinations in 96 patients with diversion of urine, the effects of urinary stasis on serum electrolytes and the acid-alkali balance are demonstrated and discussed. Early correction of urinary stasis is necessary in order to avoid any impairment of the distal functioning of the tubules and the collecting tubes. The special position of serum chloride in any diversion of urine is demonstrated.

[Experiences with lymphadenectomy in testicular tumors].

The results of 48 transperitoneal, bilateral lymphadenectomies are analysed. In stage I and II we achieved a 2-year survival time of 85.2%. The operative approach is described. The findings in patients without response to the therapy are emphasized and discussed.
