Combined retrograde-antegrade ureteral stent passage: salvage procedure for a ureteral leak.

The authors describe a stent placement procedure for treatment of an infected ureteral leak after failure of traditional antegrade and retrograde approaches. In this procedure, a guide wire was placed across the distal ureteral segment into a urinoma with use of cystoscopic guidance. Thereafter, an antegrade approach was used to pass a wire loop snare, capture the guide wire, and withdraw it through the proximal ureter for subsequent stent passage. This approach allowed percutaneous stabilization of a ureteral leak in a patient who would have otherwise required immediate surgical repair.
