The demand for transplantation exceeds the availability of cadaveric organs, which is why the importance of living, related kidney transplantation is increasing. In our study we wanted to evaluate the experiences of living related donors (LRD). Between 1973 and 1996, 1325 kidney transplantations were performed at our Department. Of these 1247 were from cadaver donors while 78 were from LRD. We contacted each living donor by post. We carried out a physical examination, laboratory tests, ultrasound and isotope investigations and they were interviewed and completed a questionnaire. Thirty previous kidney donors came to our Department who were all blood relatives of the recipients. In the recipient group, 16 still have a functioning kidney, the average time since transplantation being 8.92 years. The longest kidney survival time is 18 years. All the donors willingly donated their kidney, none was worried about their own health and their only concern was whether the kidney would function or not. Regarding general attitudes towards living related organ transplantation, all were in favour of blood relative donor transplantation and also husband/wife transplantation. Opinions regarding non-related transplantation were more mixed; 63.3% would have given their kidneys to a friend, only 46.6% to a stranger. Almost two-thirds (63.3%) of donors were not in favour of selling and buying organs but, controversially, they would have bought an organ had one been available. All agreed that the donation did not change their general health. In conclusion, the donors of living, related kidney transplantation all agreed that it was a good thing to donate; All confirmed they would go through the same procedure again in order to help. Apart from one person, who emphasised that he is agnostic, all belonged to a Christian religion.

the Optimal mode Of therapy for pahypertensive group than in the normal one. We carried out a scintigraphy of the kidney with Tc99mMAG-3. The mean value of the glomerular filtration rate calculated from the MAG clearance was 98.1 ml/min and this value is higher than half of the normal isotope clearance value, i. e. higher then the expected value for a single kidney. We conclude that no impairment of renal function is observed in the living, related kidney donors. In 16.66 % a mild hypertension developed. With isotope investigation we found hypertrophy of the remaining kidney. Thus, after a correct preoperative assessment, unilateral nephrectomy has no long-term consequences in healthy donors.

Renal transplantation is the optimal mode of therapy for patients with end-stage renal disease; the results are even better with living related donors. This procedure, therefore, favours the recipients, but what are the consequences for the donor? At our Department, between 1973 and 1996, 1325 kidney transplantations were performed, 78 from living, related donors (5.89%). We decided to follow up these patients and investigate the function of the remaining kidney and also their current general health status. Thirty donors (38.4%) were investigated. Of these, 25 of had normal blood pressure and 5 were hypertensive, needing antihypertensive treatment. The average age was higher in the hypertensive group (60.2/53.25 years). The time interval since transplantation was longer in the hypertensive group than in the normal one. We carried out a scintigraphy of the kidney with Tc-99mMAG-3. The mean value of the glomerular filtration rate calculated from the MAG clearance was 98.1 ml/min and this value is higher than half of the normal isotope clearance value, i.e. higher then the expected value for a single kidney. We conclude that no impairment of renal function is observed in the living, related kidney donors. In 16.66% a mild hypertension developed.

Kidney transplantation is a widely used method throughout the world for the treatment of end-stage renal disease. Following the pioneering work of Szeged Medical University Hospital and Miskolc District General Hospital, the first successful kidney transplantation in Hungary was performed at the Department of Transplantation and Surgery at Semmelweis Medical University on November 16, 1973. This patient is still alive with a functioning kidney graft after 21 years. We report herein our review of the global results of Hungarian kidney transplantation. Hungary is a medium-developed country with a population of over 10 million where the gross national product is about 4000 U.S. dollars per person per year. In Hungary there are 49 dialysis centers, 4 immunological laboratories, and 4 transplantation centers.

MLC was performed preoperatively in 35 out of 57 candidates for renal transplantation. Three patients developed acute pancreatitis in the early postoperative stage, 2 of them died. In these three cases MLC revealed complete non-reactivity of the recipient lymphocytes, compared with the donor as well as with the positive control lymphocytes. None of the other patients showed this phenomenon and none of them developed acute pancreatitis. It is suggested that the recipient's immune responsiveness may be involved in the aetiology of the production of acute pancreatitis after renal transplantation.
