Application of urinary fistula classification standard after renal transplantation: Analysis of 68 cases / 中国组织工程研究

ABSTRACT

1 313 patients who received renal transplantations at Department of Urology, Research Institute of Field Surgery, Daping Hospital, Third Military Medical University of Chinese PLA from December 1993 to October 2008 were selected in the experiment. Urinary fistula occurred in 68 patients of them after renal transplantation. In order to make diagnosis more standard, 68 patients was classified in accordance with diagnostic classification standards after renal transplantation. The 68 patients were divided into simple and complex urinary fistulas in accordance with lesion degree. They were divided into low, high and multiple fistulas in accordance with the position and etiology. 47 (69.1%) of 68 cases were simple urinary fistulas 42 cases were because of terminal ureteral necrosis; 4 cases were because the anastomosis was mended unsuitably; 1 case was because of poor healing of anastomosis due to infections. 21(30.9 %) cases were complex urinary fistulas. The position of orificium fistula orificium fistula located at renal pelvis, ureter and anastomosis were 2, 2 and 11 cases, respectively. 6 cases had ureteral necrosis longer than 2 cm. The times of repair 11 cases had 1 time, 5 cases had 3 times, 3 cases had 3 times and 2 cases had 4 times. 2 cases (2.9%) died because of severe pulmonary infection caused by urinary fistula. Result suggests that there are two advantages of dividing urinary fistula into the simple and complex types after renal transplantation one is that the diagnosis of urinary fistula is more carefully and standardized, and the other is that doctors can make the best choice for treatment in order to get the best efficacy.
