[Acute papillary necrosis in transplanted kidney].

After a short literature survey, indicating the rarity of acute papillary necrosis in transplanted kidneys, the authors reported one of their patients, aged 32, with transplanted dead body kidney from a male, aged 30, with blood group compatibility and compatibility of two antigens in locus A. Two hemodialysis were necessiated because of acute tubular necrosis in the transplant. After the second one, performed 10 days after the transplantation, the patient felt very strong pains in the region of the transplant, edema around it and hypovolemic shock.

[Urea kinetics model of patients on programmed hemodialysis].

Fifty three patients with programmed hemodialysis, in a stable state were studied to the method of urea-kinetic modelling. A high correlation relationship was established between the pre-dialysis values of urea nitrogen in blood and the protein import, calculated from the quantity of the endogenously produced urea nitrogen. The best rehabilitated patients (41,5%) proved to introduce 1,0-1,6 g/kg body weight proteins and maintain a concentration of blood urea nitrogen from 65-95 ng% (32,14-33,8 mmol/1).

[Viral hepatitis associated with prolonged hemodialysis treatment].

Viral hepatitis has a high incidence both among patients on hemodialysis and among the attending personnel. A clinical epidemiological study on hepatitis epidemic was carried out at the department of hemodialysis--Research Institute of Nephrology, Urology, Hemodialysis and Transplantation--for an eight-year period. Twenty two per cent of the patients were affected by hepatitis infection and 27.

[Acute papillary necrosis in the transplanted kidney].

After a brief literature survey revealing the rarity of the papillary necrosis in transplanted kidneys, the authors report the case of one of their patients, aged 32, transplanted a corpse kidney of a 30-year old male with blood-group compatibility and with coincidence of the two antigens in locus A. Regardless of the increased diuresis of the patient to 3-4 1 within 24 hours, its nitrogen bodies persisted their elevation, necessitating two dialysis. After the second dialysis performed on the tenth day after the transplantation, the patient had very strong pains in the transplantation region, edema around it and a hypovolemic shock.
