Medications to ease kidney stone surgery access
Treatments studied
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This trial tests whether two common medications—tamsulosin and aminophylline—help surgeons access kidney stones more easily during a minimally invasive procedure called retrograde intrarenal surgery (RIRS). The goal is to make the surgery smoother and potentially reduce complications.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Age 18 or older
- One kidney stone that is 2 cm or smaller on imaging
- Scheduled for primary retrograde intrarenal surgery (a scope-based stone removal procedure)
- No previous ureteral stent (tube) placed on the side being treated
- No active urinary tract infection or positive urine culture before surgery
- Able to take study medications for 7 days before surgery

Other trials that look related to this one.
This study looks at whether placing a temporary tube (called a stent) in the ureter after kidney stone surgery is always necessary. Some patients get a stent to help urine flow, but it can cause discomfort. The trial aims to see if skipping the stent is safe and leads to fewer symptoms. If you are having kidney stone surgery, participating might help determine the best approach for recovery.
This trial is looking at whether placing a small tube (stent) in the ureter before a type of keyhole surgery for kidney stones helps with outcomes like pain and success of the procedure. It aims to see if this pre-treatment makes the surgery easier, potentially reducing complications and improving stone removal.
This trial compares two different surgeries for removing a single kidney stone that is 2 to 3 centimeters in size. One method uses a flexible scope with a suction tube, and the other uses a small incision in the back. The goal is to see which works better and has fewer side effects.
This trial tests different types of tubes (called ureteral access sheaths) used during a minimally invasive kidney stone removal procedure called RIRS. The goal is to see which type works best and causes the least damage to your ureter (the tube that carries urine from your kidney).
This trial compares a vacuum-assisted ureteral access sheath to a standard one during kidney stone surgery (retrograde intrarenal surgery). The goal is to see which might work better and be safer for patients.
This trial tests two medications, mirabegron and tamsulosin, to see which works better for helping a single ureter stone pass without surgery. If you have a stone between 4 and 10 mm in size, are 18-75, and have good kidney function, this study may be for you.
