RESUMO
<p><b>OBJECTIVE</b>To study pathogeny, diagnosis and treatment of ureter fistula after renal transplantation.</p><p><b>METHODS</b>The clinical data from 30 cases after renal transplantations were analyzed.</p><p><b>RESULTS</b>Four patients received conservative treatment, and 2 repairment of the fistula. Eleven patients had resection of the ureter or adjustment of the kidney, followed by the anastomosis of the ureter and bladder again. After the turning of the bladder's lamella, 13 patients were given 20 - 24 Foley's tube connecting the pelvis and bladder and nine of them were not subjected to re-anastomosis waiting for the pelvis crawling to the bladder as a tunnel. The one-year survival rates for 30 cases and kidneys was 96.7% (29/30) and 86.7% (26/30) respectively.</p><p><b>CONCLUSIONS</b>There a lot of causes for ureter which are fistula, running related to every aspect of transplantation. Early diagnosis and treatment is important to prognosis. Most patients need reanastomosis. According to the blood stream, edema, length of the ureter, operative procedures are selected to ensure free of strain.</p>
