Double pigtail (DJ) ureteral stents are used to prevent ureteral obstruction and allow easy passage of urine. Stent migration is a well recognized complication of stents, but migration into the renal pelvis is rarely documented. We present a case of simultaneous proximal and distal migration of a stent and discuss briefly, the etiological factors for the phenomenon and associated problems in management.
