Abstract
BackgroundThe most serious complication of ureter stent is long-term retention of ureteral stent and stone formation around the stent.Case presentationA 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.ConclusionsCombined endoscopic techniques in the prone split-leg position can effectively and safely manage severely encrusted stents.
Highlights
The most serious complication of ureter stent is long-term retention of ureteral stent and stone formation around the stent
Ureteral stent was widely used in ureteral calculi, stricture operation, ureteral injury and relieving tumor compression
It is suggested that cystoscopy and / or X-ray should be used to check the ureteral stent for signs of encrusted and normal function
Summary
The most serious complication of ureter stent is long-term retention of ureteral stent and stone formation around the stent. If the stone around the stent tube is too large to be completely removed, it may need to be treated by extracorporeal lithotripsy or surgery many times, which can cause great pain and financial burden to the patients. This report presents an interesting case of successful removal of an encrusted ureteral stent in a single session by endoscopic combined intrarenal surgery (ECIRS). Computed tomography (CT) examination reported that a single large stone, located in the renal pelvis and bladder, wrapped around the end of the stent tube, with a length of more than 2 cm (Fig. 2).
