Retrograde ureteral access after cross-trigonal ureteral reimplantation can be challenging. We present our experience with retrograde ureteral catheterization and flexible ureteroscopy after Cohen cross-trigonal reimplantation in patients presenting with ureteral stones.
Cystoscopy is performed and a Tiemann ureteral catheter is inserted into the involved ureteral orifice. A retrograde ureterography is performed and hydrophilic guide wire is passed up to the kidney. A dual-lumen ureteral access sheath is then passed under x-ray control underneath the ureteral stone. The flexible ureterorenoscope is passed under x-ray control up to the stone which is then fragmented with a holmium laser.
From June 2006 to June 2010, this technique was successful in 8 patients without acute or delayed sequelae.
Where the endourological expertise is readily available, the ureter can be accessed retrogradely even after Cohen cross-trigonal ureteral reimplantation in a safe, straightforward and effective modality.
