[Percutaneous Fibrin Glue Injection for Persistent Urinary Leakage after Partial Nephrectomy : A Case Report].

A 69-year-old man with left atrophic kidney was referred to our hospital because of a 5.7 cm solid mass in the lower pole of right kidney revealed by computed tomography for evaluation of aortic aneurysm. An open transperitoneal partial nephrectomy was performed, and final pathological diagnosis was clear cell carcinoma, grade 2, pT1b, pNx. One month postoperatively, a computed tomography revealed 16 cm retroperitoneal fluid collection which was diagnosed as urinoma due to urinary leakage from partial nephrectomy scar of the right lower calyx. Following percutaneous drainage of a 6 Fr Pigtail catheter, 6 Fr double-J ureteral stent and urethral catheter were placed, but the discharge through the percutaneous drain continued to be 700 to 1,000 ml/day. Forty-one days after drainage, two open-end catheters (5 Fr) were directed into the urinary fistula lumen through the percutaneous tract and 6 ml of fibrin glue was injected under fluoroscopic guidance. Four days later, another 2 ml of fibrin glue was injected because of a small amount of residual urinary leakage and percutaneous drainage catheter was removed. Thereafter, urinary leakage was completely cured and ureteral stent and urethral catheter were removed.
