Neovesicovaginal fistula due to a retained double-J stent in an ileal neobladder: surgical management and clinical considerations

We report a neovesicovaginal fistula in a woman with an ileal neobladder after radical cystectomy, caused by prolonged retention of a double-J ureteral stent that became calcified. The patient presented with continuous urinary leakage and recurrent infection. Diagnosis was confirmed by cystoscopy, methylene blue testing, and cystography. Transvaginal repair with two-layer closure and anterior vaginal wall reinforcement was performed; a Foley catheter was maintained for 21 days. Recovery was uneventful; the catheter was removed after imaging confirmed no urinary leak. This case emphasizes the need for stent surveillance and supports transvaginal repair as an effective option in selected neovesicovaginal fistulas.
