Alpha-blockers before kidney stone surgery: a randomized study
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This trial tests whether taking an alpha-blocker medication before a type of kidney stone surgery (flexible ureteroscopy) helps the surgeon insert the ureteral access sheath more easily. Alpha-blockers are drugs that relax certain muscles, possibly making the procedure smoother and safer.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older
- You have kidney stones that need to be removed with a flexible ureteroscope (a thin tube with a camera)

- You are not pregnant
- You have not had a ureteroscopy or had a double-J stent placed on the same side in the last 3 months
- You do not regularly take alpha-blockers for an enlarged prostate or to help pass ureteral stones

Other trials that look related to this one.
This trial compares two ways of removing kidney stones during a procedure called flexible ureteroscopy. One method uses a special sheath that helps suction out stone fragments, which may improve stone removal and recovery.
This trial compares two different tubes used during surgery to remove kidney stones. The goal is to see if one type works better than the other for clearing stones safely.
This study tests whether numbing medicine placed directly into the bladder can reduce pain after a ureteroscopy procedure for kidney stones. It may help you feel better and use less pain medication after surgery.
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.
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 tests if using a special suction tube during surgery to remove kidney stones can lower the risk of infection. It is for people with small to medium-sized stones in the kidney or upper ureter.
