“…At our institution we have experience with this procedure, which is performed with rigid endoscopic material, without the need for antegrade ureterorenoscopy, being a simple technique to perform and with success rates of around 80% for the resolution of ureterointestinal strictures. 4,5 Unlike endoureterotomy with the Lovaco technique, in the clinical case we present the balloon catheter was used to prevent migration of the lithiasis, inflating the catheter in an area proximal to it, not on the ureteroileal junction, or on the lithiasis itself. Regarding the energy used for the incision, although we accept that the cut could have been made with a holmium laser, the Collins knife is an element that provides the possibility of performing mechanical traction in the incised area for better visualization, a cut that allows to distinguish between different types of tissue (ureteral thickness, fat, etc.…”

Introduction: In patients with a history of radical cystectomy and with intestinal diversion, urolithiasis in the upper urinary tract is a frequent event. Material and methods: We describe for the first time a case of retrograde endoureterotomy used to treat a calculus proximal to the ureterointestinal junction. Results: This technique is of interest when antegrade access is not possible. In our example, after passing the guidewire percutaneously, and externalize it through the stoma, the left meatus was reached with a resectoscope inserted through the ileal duct. After the use of a balloon to prevent migration of the calculus, a retrograde endoureterotomy was performed with a Collins knife and the stone removed. The patient’s progress was satisfactory. Conclusion: Endoscopic management of calculi in patients with intestinal diversion can be performed with different approaches. We recommend retrograde endoureterotomy as a feasible treatment option for the removal of impacted calculi at the ureterointestinal junction.
