The pressure conditions in the pancreatic duct of healthy dogs and of animals with experimentally induced acute serous or necrotic pancreatitis were studied with the Hess-type manometer successfully applied in biliary surgery. In acute pancreatitis hypertension was observed which was more marked in the group with necrotic pancreatitis.

Three types of plications were performed on dogs: 1. modified mesenterial plication; 2. transjejunal internal splinting; 3. intestine duplication according to Noble. No passage disorder or abnormal circulation were observed; compared with the values of the control dogs isotope activity was the same after plication. Thus, there is no danger of impaired circulation after this type of operation.

Experience gained in the treatment of 38 malignant testicular tumour patients is reported. The results of castration + chemotherapy (all these patients died within one year) are compared to those of retroperitoneal lymphadenectomy in 15 patients. To preserve the ability of ejaculation the lymph glands accompanying the iliac artery were spared on the contralateral side. Experience has shown that chemotherapy is considered necessary even when the histological finding of the lymph node is completely negative.

The protective action of the radiation detoxified endotoxin preparation (Tolerin) on the endotoxin shock of dogs was studied. Endotoxin shock was induced by the intravenous administration of 2 mg/kg of Escherichia coli endotoxin. It was found that the intraperitoneal administration of 4 mg of radiation-detoxified endotoxin (Tolerin) 48 hours prior to the inducement of shock prevents the drop in blood pressure and the decrease of cardiac output which promptly appear in the acute phase of endotoxin shock.

Pyeloureteral obstructions of various pathogeneses and their complications can be visualized satisfactorily be means of intravenous urography. Of the other diagnostic methods angiography was found to be the most useful, no retrograde examination was carried out. When distension of the end of the calyx or obvious parenchymal lesion appears, plastic operation must be performed irrespective of the patient's age, the presence of infection or anomaly of the localization. Only kidneys which have lost their functions should be removed. In the operation the pyeloureteral boundary is always excised, the new transition is secured by splinting and a transrenal drain is used. Secondary nephrectomy had to be performed in a single case. One-year and three-year intravenous urographic check-ups showed in 72 of the 100 cases good, in 19 satisfactory results, in 8 cases the pyeloureteral boundary was funnel-shaped, but the dilatations of the calyx-ends remained unchanged. Pyeloplasty is no longer a high-risk operation.

Late results of the bladder-flap method Boari--Mezö fulfilled expectations only in the correction of ureteral lesions of gynaecological origin. With appropriate technique even 5 to 10 cm long sections of the ureter can be replaced and in one-third of the cases the late results, too, are good. The authors are convinced that Boari plasty is not an anti-reflux operation and the results are poor in cases of specific ureteral stricture. The operation is recommended for the correction of congenital malformations, fibrous periureteritis and strictures after nephrolithotomy when the strictures are long and simple ureteral neoimplantation is technically impossible.
