Influence of renal angiography in living potential kidney donors.

The angiograms of 258 potential kidney donors were retrospectively reviewed to assess the influence of angiography for deciding whether or not to accept the potential donor for nephrectomy and which kidney to use for transplantation. Twenty-five potential donors were rejected. In only 8 of these was angiography necessary to reveal the pathology. Angiography was found to be important in deciding which kidney to donate. In 81 donors the right kidney was used for donation and in 50 this decision was based on findings at angiography.

[Severe, symptomatic hyponatremia].

Severe hyponatremia (serum sodium levels less than 120 mmol/l) is associated with increased morbidity and mortality. We report three cases where patients developed hyponatremia and severe neurological manifestations after medical treatment. The first two patients experienced episodes of general seizures and coma, but recovered in 24 hours without neurologic sequelae after correction of the electrolyte disturbance. The third patient developed the syndrome central pontine myelinolysis with pseudobulbar palsy and quadriparesis. Marked improvement occurred, however, and in three months the patient was almost completely recovered. The development of hyponatremia deserves special attention in connection with the use of diuretics, infusion of sodium-free carbohydrates and immediately after operation.

[Correction of severe hyponatremia].

Profound hyponatremia is a life-threatening emergency which can result in permanent neurological damage. The rate at which severe hyponatremia should be corrected is the focus of clinical debate. It is important, however, to differentiate chronic from acute hyponatremia and to develop a plan for correcting hyponatremia. A treatment regime is suggested.

[Kidney transplantation in Norway].

Twenty years ago, in 1969, a national kidney transplant program was established, based on uniform indications and preparations for transplantation. Since 1983, all transplants have been performed at one centre. We describe the organization, development, treatment policies and results of the program. The national transplant rate of 42 patients per million population per year (p.m.p.) keeps up with the demand. In contradiction to the international experience of rapidly expanding waiting lists and dialysis populations, a balance has been achieved in Norway, with a high transplant rate, a restricted and stable waiting list (mean 23 p.m.p.), waiting time (mean 5 months) and dialysis population. Approx. 80 per cent of all patients requiring long term renal replacement therapy actually receive a transplant, as against approx. 50% in Western Europe. Seventy-five to 100 per cent of the transplants function for more than a year, and 55-80 per cent for more than five years, depending on the donor and HLA compatibility. Other significant risk factors are age and HLA sensitization. Since 1983, 46 diabetics with renal failure have been treated by combined renal and pancreatic transplantation.

[Treatment of chronic kidney failure with dialysis and transplantation. Development, need and organization in Norway].

Treatment of chronic renal failure by dialysis and renal transplantation has been developed over the last 20 years in Norway. 17 local nephrological units with dialysis departments cooperate with one transplantation center in Oslo. The number of new patients starting renal replacement therapy has increased only slightly during the last five years. The mean number of new patients in the period was 52 per million inhabitants per year. The proportion of elderly patients accepted for renal replacement therapy was high (39% above 60 years of age) and approximately 15% of the patients had diabetic nephropathy. Due to an active transplantation policy, the proportion of patients alive on dialysis is low (18%), compared with 82% alive with a functioning graft. The number of patients on dialysis has declined slightly the last four years. The proportion of patients on chronic ambulatory peritoneal dialysis (CAPD) is low (13%), and the number of patients on home hemodialysis has declined in the last five years. Predialytic transplantation has been performed in 18% of the patients starting renal replacement therapy during the last five years. Due to a high transplantation rate and a large number of predialytic transplantations, it has not been necessary to increase the capacity for dialysis in the last five years.

[Costs of care in uremia. How much does kidney transplantation cost?].

The cost of kidney transplantation and hemodialysis have been recorded (in 1986). Tissue typing, operation and initial stay in hospital cost NOK 103,000 per patient, and further treatment for the first year after operation NOK 114,000. Subsequent annual costs were NOK 70,000, mainly for drugs. Hemodialysis costs NOK 287,000 per year. Transplantation was cost-effective by almost NOK one million per patient over a five-year period. If the current high national rate of transplantation (42 patients per million), which keeps both the national waiting list (23 patients per million) and the dialysis population at a low level, is sustained over the next five years, then total national expenditures for dialysis and transplantation are predicted to be approx. NOK 400 millions. If no transplants were performed during this period the waiting list would increase to 175 patients per million, and expenditures (for dialysis) to approx. NOK 750 millions. Additional huge investments would be needed in order to expand the facilities for dialysis. Because of high transplant rate, only 18 per cent of all treated uremics in Norway are now on dialysis, versus 73 per cent in Western Europe. Since transplantation is much cheaper than dialysis, national expenditures per treated patient are lower in Norway than in any other country.

Elimination of iohexol, a low osmolar nonionic contrast medium, by hemodialysis in patients with chronic renal failure.

The dialyzability of iohexol was examined in patients with chronic renal failure on long-term hemodialysis treatment. Eight patients had iohexol (Omnipaque 240 or 350 mg I/ml) injected in doses between 98 and 1,493 mg I/kg body weight (BW) 25 h (mean time) before start of hemodialysis. Dialysance of iohexol was 81 +/- 15 ml/min (mean +/- SD) compared to 120 +/- 16.8 ml/min for creatinine. Elimination half-life for iohexol during hemodialysis was 3.9 +/- 1.1 h while plasma clearance was 64 +/- 17 ml/min. The distribution volume calculated (0.25 +/- 0.05 liters/kg BW) confirms previous observations with distribution in the extracellular fluid only. Before the start of hemodialysis 36 +/- 28% of the dose injected was eliminated, indicating some extrarenal elimination. After 4 h of hemodialysis 72 +/- 11% of the dose was removed.
