Spontaneous healing of ureterogenital fistulas: selection criteria.

We present 12 cases with spontaneous healing of ureterovaginal (11 cases) and ureterouterine (1 case) fistulas. In every case disappearance of the fistula with normal renal function and restoration of the excretory tract was obtained. IVP and retrograde pyelographs were performed in every case. Spontaneous healing is feasible under the following conditions: continuity of the ureteral lumen and normality of the infralesional ureter. Spontaneous healing is independent of the number of affected ureters, age, gynecological pathology, gynecological intervention, latency period, urographical findings, duration of incontinence, and urinary infection.
