Comparing symptoms from different ureteral stents after stone surgery
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
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.

This trial compares two types of disposable flexible ureteroscopes to see which works better for removing kidney stones in children. If your child has a single kidney stone or multiple stones that add up to less than 20 mm, this study may help guide better treatment.
This study compares three different ways of placing a small tube called a stent in the ureter after stone-removal surgery. The goal is to find the best method to reduce discomfort and improve recovery.
This trial compares two types of ureteral stents (small tubes that help urine drain from the kidney to the bladder) in children having surgery for kidney stones. The goal is to see which type causes fewer symptoms like pain or discomfort.
This study looks at whether choosing the stent length based on your CT scan reduces discomfort after kidney stone surgery. It compares symptoms in people who get a stent sized this way.
This trial studies whether some people can avoid getting a ureteral stent after ureteroscopy and lithotripsy for a kidney stone. It may help reduce stent-related discomfort while still keeping outcomes safe for the stone problem.
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.
