Ureteral stent on plain abdominal radiography
Ureteral stent on plain abdominal radiography
Ureteral stents are placed endoscopically over a guidewire into the ureter. The proximal and distal curls (ie, pigtails) become apparent when the guidewire is removed. Proper positioning is indicated by placement of the proximal curl in the renal pelvis and distal curl in the bladder.
