A 16-year-old man with horseshoe kidney presented with a right-sided forgotten double J stent (DJS), 1 year after bilateral percutaneous nephrolithotomy. X-ray of the kidney, ureter and bladder showed bilateral residual stones with no encrustations or stone formation on the DJS. Initial attempt of DJS removal using 22 French (Fr) cystoscope and 6/7.5 Fr semirigid ureteroscope failed due to resistance while pulling the DJS and inability to uncoil the upper end of DJS. Finally, percutaneous antegrade scopy was done suggestive of submucosal impaction of the forgotten DJS in upper ureter. The overlying mucosal bridge was cut using holmium: Yttrium Aluminum Garnet (YAG) laser and the DJS was retrieved. The index case highlights an unusual cause of entrapment of the DJS and whenever resistance is encountered, the use of force should be avoided and the cause of resistance should be troubleshooted, thereby preventing serious injuries like ureteral avulsion.
