Abstract

Background
One of the most common problems after kidney transplantation is urological complications. Urine leakage is the most common early urological complication after kidney transplantation. The aim of the study was to study the effect of plate-let-rich plasma (PRP) on urteteroneocystoanastamosis (UNCA) in a recipient after kidney transplantation.
Methods
This method was applied to 14 recipients with standard UNCA by Lich-Gregoir. Before the manipulation, 50 mL of venous blood was taken from each recipient. The blood is placed in test tubes with a sodium citrate content of 3.8%. The tubes were centrifuged twice; 10 minutes at 2,400 rpm and 15 minutes at 3,600 rpm. After the first centrifugation, the middle layer with leukocytes and platelets was collected and transferred to other test tubes using a long needle. After the second centrifu-gation, the platelet count was 125000010(9)/L±35000010(9)/L platelets and increased 6.4 times compared to the initial amount. Before use, PRP was activated with a 10% solution of calcium chloride and a gel-like mass was obtained. Then the PRP gel was applied to the UNCA line in the recipients.
Results
In all cases, there were no early urological complications. The graft function was satisfactory. There were no reanastomosis during and after surgery in the recipients.
Conclusions
UNCA using PRP-gel is a highly effective, cost-effective method of preventing urological complications. However, this method of surgical treatment does not provide a 100% guarantee of the success of the operation, which requires additional study for the application of this method of treatment.
