Kidney stone and tumor treatment study

This study follows people with kidney cancer who are scheduled for surgery to remove their tumor. It aims to learn more about the disease and how it behaves over time.

This study watches people with upper tract urothelial cancer who are having surgery to remove the kidney and ureter. It aims to collect information to better understand the disease and improve future care.

This study compares simply watching a kidney stone over time versus having surgery to remove it, in children and teens who have a small, symptom-free stone. The goal is to see which approach leads to better health outcomes.

This study looks for better ways to predict when kidney stones may come back and what complications might happen. It may help doctors personalize follow-up and prevention plans based on information collected from you.

This study looks for “biomarkers,” which are measurable signs in samples like urine or blood, to help understand and detect recurring urinary stone disease. It may help future patients by improving how doctors predict stone recurrence or identify stone types.

This study looks at the use of a ureteral access sheath (a tube that helps the surgeon reach the kidney) in people who already have a ureteral stent (a small tube placed in the ureter) and are having a stone removal procedure called ureteroscopy. It aims to find out if using this sheath is helpful for treating stones in the kidney or ureter.
