Practical approach to terminate urinary extravasation: percutaneous fistula tract embolization with N-butyl cyanoacrylate in a case with partial nephrectomy.
A 35-year-old woman who underwent partial nephrectomy had prolonged postsurgical urinary extravasation that led to a percutaneous fistula. A double-J catheter used as a ureteral stent during surgery was in place. A percutaneous pigtail nephrostomy was inserted on the 15th postoperative day but drainage continued. Antegrade pyelography demonstrated extravasation at the lower pole calyx. The double-J stent was removed on the 21st postoperative day, and a retrograde pyelogram showed no obstruction. Because drainage still was excessive on the 25th postoperative day, the fistula tract was embolized percutaneously with N-butyl cyanoacrylate, a tissue adhesive material. Drainage ceased immediately after the procedure, and control pyelography confirmed no extravasation. The patient was discharged on the 28th postoperative day. The patient had no additional complications at 36-month follow-up.
