Abstract
Renal transplantation is considered the treatment of choice in most cases of renal failure; the urologic complication rate ranges 1 to 10% in different surveys. This work was aimed at evaluating the application and results of interventional radiology in these cases. Since 1983, 24 patients (20 males and 4 females) whose age ranged from 18 to 63 years (mean age: 42 years) have been submitted to percutaneous maneuvers in our department. Thirty-four complications were treated: 14 stenoses, 11 fistulas, 7 urinomas and 2 transient obstructions. Complete success was obtained in 15/24 patients (62.5%), while 7/24 patients (29.16%) underwent reoperation and in 2/24 cases (8.34%) a definitive pyelostomy catheter was inserted. In 7 stenosis cases ureteroplasty was successfully performed and a double-J endoprosthesis inserted; the follow-up results (5-21 months) were satisfying in all cases. The only complication was one case of endoperitoneal hematoma. Considering the good results obtained, the low morbidity and mortality and the low cost, percutaneous maneuvers must be considered the treatment of choice in the urologic complications of renal transplants. When the percutaneous treatment of the main lesion fails, pyelostomy does nonetheless allow the drainage of urinary collections, the maintenance of renal function and the improvement of local and general conditions, which makes it easier to reoperate under elective conditions.
