Abstract

A 48-year-old man with a history of cerebral infarction presented with gross hematuria. The patient's limping accompanies twisting trunk on his walking. The diagnosis was right upper ureteral stone. Prior to Extracorporeal shockwave lithotripsy (ESWL) ureteral stent was inserted. After the second ESWL ureteral stent was displaced upwardly without patient's unknown. Retrograde intrarenal surgery (RIRS) was performed for both removal of ureteral stent and fragmentation of residual stone. Spontaneously, post RIRS ureteral stent was migrated upwardly to the same position. Ureteral stent migration is uncommon. Twisting walk may cause the position of ureteral stent upwardly.
