Dual stent placement for the treatment of a persistent urine leak after partial nephrectomy

Persistent urine leak is a known complication after partial nephrectomy. In the present case, a partial nephrectomy was performed to remove a large, centrally located, renal mass in an elderly man with a solitary functioning kidney. A persistent urine leak refractory to single stent drainage was successfully treated after two stents were placed in the ipsilateral renal unit such that the upper and lower calices were drained by separate stents.
