A Rare Case Report on Forgotten Double J Stent in Crossed Renal Fused Ectopia

We present a case of forgotten stent post ureteric stone management in CRFE which was removed by retrograde intrarenal surgery (RIRS). Ureteral double J (DJ) STENT has now become one of the most commonly used tools in endourology. Complications are bound to occur if forgotten to remove, such as encrustations, infection, migration, renal dysfunction, hydronephrosis. Crossed renal fused ectopia is a very rare congenital malformation due to abnormal kidney ascent with fusion during embryogenesis in the first trimester. We report a very rare case of forgotten DJ stent in crossed fused ectopia, in 66 years old diabetic patient post left ureterorenoscopy (URS) done 3 years back. Retrograde intrarenal surgery (RIRS) was done for DJ stent removal Right. Endourological management can achieve a safe and successful outcome in the treatment of forgotten stent. Proper education and counselling of patients and relatives before and after stenting with maintaining stent registry may help reduce incidence of forgotten stents.
