Comparing two types of ureter stents after kidney stone surgery
Part of Kidney & urinary clinical trials.
This study compares a regular double J stent with a newer Comfi J stent to see which causes fewer symptoms after ureteroscopy for kidney stones. It may help patients who need a temporary stent choose one with less discomfort.

This trial compares two types of temporary drainage tubes (stents) placed in the ureter—the tube that carries urine from kidney to bladder—after surgery to remove kidney or ureteral stones. The study measures which stent causes fewer uncomfortable symptoms during the 2-week recovery period.
This study compares four types of ureteral stents to see which causes the fewest side effects after kidney stone treatment. If you have a stent placed after stone surgery, your symptoms will be tracked to help find the best option.
