[Urologic complications in kidney transplants: experience in 274 transplants]. / Le complicanze urologiche nel trapianto renale: esperienza su 274 trapianti.

The urological complications after a renal transplantation still represent an event anything but rare, ranging, according to the different statistics, from 0.9% up to 23%, with a mortality between 0 and 25%. In this work done by the Verona Centre the experience on 274 transplantations is reported. The urological complications weighed with 6.2% and absence of mortality among the patients. The importance of the prevention and precocious diagnosis is confirmed.

Renal needle biopsy of the transplant kidney: vascular and urologic complications.

The authors reviewed the complications of 114 needle biopsies performed in 103 transplant kidneys. The diagnostic and therapeutic approach has changed markedly as a result of the introduction of Doppler ultrasound and the possibility of selectively embolizing fistula tracts. Macroscopic haematuria was the most frequent complication (5%); in one case it appeared 1 week after biopsy and was complicated with obstructive anuria due to a pyeloureteric clot. The incidence of arteriovenous fistulae was fairly low (0.9%); a selective renal angiography was performed, confirming the vascular lesion and allowing its selective embolization. Perirenal blood collections were also rare and the amounts were small.
