Abstract
BACKGROUND: The most serious complication of ureter stent is long-term retention of ureteral stent and stone formation around the stent. CASE PRESENTATION: A 51-year old female patient with left ureteral stent placed 2 years before developed both pyelic and vesical stones on the two ends of the double J was admitted to our hospital. Intravesical lithotripsy, retrograde ureteroscopy, and percutaneous nephrolithotripsy were performed with the patient in the prone split-leg position. All the stones and the ureteral stent were successfully removed in a single session. CONCLUSIONS: Combined endoscopic techniques in the prone split-leg position can effectively and safely manage severely encrusted stents.
