Case in which percutaneous fibrin glue injection was useful for refractory urinary fistula following robot‐assisted partial nephrectomy

Introduction Urinary fistula is a rare complication following robot‐assisted partial nephrectomy. For cases refractory to conservative treatment, only ureteral stent placement and percutaneous drainage are the established treatment alternatives. Case presentation A 44‐year‐old man presented with urinary fistula 3 weeks after robot‐assisted partial nephrectomy for right renal cell carcinoma. Follow‐up observations were conducted for 2 weeks; however, no improvements were observed. Additionally, the patient did not improve following percutaneous drainage and ureteral stent insertion. Subsequently, the patient received percutaneous injections of fibrin glue, with the urinary fistula showing significant improvements on the following day. Conclusion Our findings indicated that percutaneous fibrin glue injection can effectively treat refractory urinary fistula following partial nephrectomy.
