Recruiting studies
- NCT07773090Recruiting
Stenting before mini-keyhole kidney stone surgery
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.
CairoAges 18–70 - NCT07700251Recruiting
Comparing two surgeries for kidney stones in children
This study compares two types of surgery for removing kidney stones in children. It aims to see which method works better and is safer for stones up to 2 cm.
Qina, South ValleyAges 1–18 - NCT06795256Recruiting
Homework for kidney stone surgery recovery
This study looks at whether giving patients homework to do after their kidney stone surgery helps them recover better. It aims to see if this approach can improve your results after a procedure called retrograde intrarenal surgery (RIRC).
AdıyamanAges 18 years+ - NCT07342361Recruiting
Using a scope through the kidney for large stones
This trial uses a special scope inserted through the kidney to break up and remove large, branching kidney stones (called staghorn stones). It may be a good option if you have this type of stone and your kidneys are working well.
CairoAges 18–70 - NCT07261995Recruiting
Shock wave vs. laser surgery for kidney stones
This trial compares two procedures to break up a single kidney stone. One uses sound waves from outside the body, the other uses a laser through a small scope. Both aim to help you pass the stone more easily.
Karachi, SindhAges 18–65 - NCT06684756Recruiting
Comparing two types of ureteral access sheaths for kidney stone surgery
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.
Tekirdağ, TurkeyAges 18–85 - NCT05738304Recruiting
Do we need a stent after kidney stone surgery?
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.
CairoAges 18 years+ - NCT07859436Recruiting
Audio consent for kidney stone surgery
This study tests whether adding a voice recording (human or AI) to the written consent form helps patients understand their upcoming kidney stone surgery better before they agree to it.
Aydin, AydınAges 18 years+ - NCT07767773Recruiting
Long-term safety of two kidney stone scope methods
This study is checking the long-term safety of two different ways of doing a kidney stone scope procedure (one uses a small tube to guide the scope, the other does not). If you had this procedure for a kidney stone (up to 20 mm) and it's been at least a year, they want to follow up with you to see how you're doing.
CairoAges 18 years+ - NCT07763613Recruiting
Study of pelvic floor strength after kidney stone surgery
This study measures a new score called the pelvic floor fatigue index, which looks at how tired the pelvic floor muscles get, in people who have a ureteral stent placed after kidney stone surgery. The goal is to see if this score can help predict or prevent bladder problems that stents can cause.
Trabzon, TrabzonAges 18–65 - NCT07655050Recruiting
Antibiotic wash during kidney stone surgery
This study tests whether washing the urinary tract with antibiotics during kidney stone surgery can help prevent infections. It's for people scheduled for a procedure called RIRS to remove kidney stones.
Çorum, ÇorumAges 18 years+ - NCT07643324Recruiting
Breathing support study during kidney stone removal surgery
This study compares two different breathing-machine settings during a minimally invasive kidney stone removal procedure to see which works better and causes fewer lung problems. You would be randomly assigned to one setting or the other during your surgery.
ÇorumAges 18 years+ - NCT07623876RecruitingPhase 2
Medications to ease kidney stone surgery access
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.
Aswān, Aswan GovernorateAges 18 years+ - NCT06723327Recruiting
How urine culture timing affects kidney stone surgery results
This study checks if taking a urine culture two weeks before kidney stone surgery affects outcomes. It may help ensure your surgery goes smoothly by confirming your urine is free of infection.
TekirdağAges 18 years+ - NCT07507656Recruiting
Stress ball for anxiety before kidney stone surgery
This study tests whether squeezing a stress ball before your kidney stone surgery can help lower your anxiety and fear, and keep your heart rate and blood pressure more stable during the procedure.
Yenişehir, MersinAges 18 years+ - NCT07076589Recruiting
New tool vs. standard tool for kidney stone surgery
This trial tests a new flexible suction tube for kidney stone removal versus the standard tube. It aims to see if the new tool works better and is safer for patients with small kidney stones.
CairoAges 14 years+ - NCT07058402Recruiting
Comparing two kidney stone surgeries for medium stones
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.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06809582Recruiting
Body position and kidney stone removal results
This study looks at how your body’s position during surgery affects how well kidney stones are cleared. If you have stones ≤2 cm and are having a scope-based kidney stone removal, you may be able to join.

Common questions
- Are there clinical trials for retrograde intrarenal surgery?
- Yes. Clin2 currently lists 18 recruiting retrograde intrarenal surgery studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a retrograde intrarenal surgery trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a retrograde intrarenal surgery trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
