[Surgically relevant problems of chronic hemodialysis in childhood].

It is reported about 100 children undergo chronic hemodialysis. The most frequent operation is to get a sufficient vascular access. The Cimino-fistula is the best access. There is no more any regularly indication creating a Scribner-Shunt. The nephrectomy as also a frequent operation is complicated by bleeding. To cure the renal osteopathy total parathyroidectomy with autotransplantation is used. Gastritis, pancreatitis and disturbance of bowel movement are seen. The enhancement of renal transplantation will help to diminish mortality of patients undergoing hemodialysis.

[The behavior of serum "liver enzyme" activity in children with chronic renal failure, hemodialysis and kidney transplantation].

Liver enzymes were measured in 24 children with different degrees of renal insufficiency, in 6 children treated by chronic hemodialysis and in 13 children after kidney transplantation. The hemodialyzed and transplanted patients have the highest ALAT activity, independently of the presence of a liver infection. The AP activity in these patient groups were not different from the reference value. The activity of ALAT, GGT and CHE, respectively were most pathologic in the hemodialysis group. The enzyme activities have not been influenced by a single dialysis and a 6-month dialysis course. In uremic and chronic hemodialyzed patients the enzyme combination of ALAT, GGT and CHE has been recommended in the diagnosis and follow-up control of a liver cell damage. In the evaluation of enzyme activities in comparison with reference values of healthy volunteers an enzyme inhibition by the uremic serum should considered.

[Can the number of donor kidneys for children be increased by using the kidneys of dead newborn infants?].

The donor pool for kidney transplantation in small children may be extended by the use of kidneys from deceased newborns. From 1973 to 1983 at our institution 189 mature newborns died, of which were 105 from the clinical point of view and 82 from the pathological-anatomical sight suitable as organ donors. The most frequent causes of death were disorders of the heart and circulation (60) and of the respiratory system (46). It is pointed to the problem of the establishment of brain death in newborns.

[Standardization of methods and assessment of conventional and radionuclide clearance investigations: recommendations of the Renal Diagnostics Study Group of the Society of Nephrology, GDR].

Recommendations of the Study Group "Renal Function Diagnostics" of the Society of Nephrology to the performance of the steady state clearance using inulin or PAH and the slope clearance with radionuclides for estimation of effective renal plasma flow are presented. These investigations are indicated in the early recognition and follow-up of latent or residual disturbance of the renal function in the creatinine-blind area. Recommendations have been done on selection and dosage of test substances, timing of examination and evaluation of results.

[Arteriovenous interposed prostheses in children for dialysis of allogenic, aldehyde preserved, form-fixed veins with silicone-coated inner surfaces].

Arterio-venous shunts of new allogenic, aldehyde-preserved, form-fixed saphena with silicone-coated inner surfaces were applied to the upper arms of seven children aged between four months and ten years. Two children died of open shunt, and two transplants underwent thrombosis, within a follow-up period of 27 months. The causes of death and thrombosis were in no way related to the transplant material. Infection, aneurysm, and stenosis did not occur.

[Growth of transplanted kidneys].

Two or more years after a kidney transplantation were determined the GFR as 51Cr-EDTA-clearance and the effective renal plasma flow as 125J-hippuran clearance. In 14 children the results of the clearance with the HLA-identity (HLA-I), the quantity of the transfusion units (TU) received before the transplantation and the duration of the cold ischaemia time (CIT) were correlated. While with HLA-I and TU no connections could be proved, the results of the clearance seemed to be reversedly proportional to the CIT (r = -0.53 and -0.64 for GFR and ERPF) for a longer time after transplantation. Different age between donor and recipient shows worse results of clearance in the group of the adults who received a kidney of a child, in contrast to the other three possible combinations of the kidney transplantation.

[Initial results of tm-PAH studies in children with kidney transplants].

In 15 children 2 months to 5 years after a transplantation of a cadaver kidney the renal function was determined by means of a clearance- and Tm-PAH-examination. Only in 4 children the Tm-PAH reached the normal value of a kidney. The calculation of the glomerulo-tubular balance results in increased values. The result for the relative tubular blood supply is normal. Compared with the values of children with an overcome haemolytic-uraemic syndrome or with a chronic glomerulonephritis or pyelonephritis shows that the renal function in children who underwent a transplantation similarly behaves as in a chronic pyelonephritis.
