L-Citrulline vs. Tamsulosin for Kidney Stone Passage
Treatments studied
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study tests whether L-citrulline (a natural amino acid) or tamsulosin (a common blood pressure medication) helps you pass a small kidney stone stuck in your ureter (the tube from kidney to bladder) without surgery. The goal is to compare which medicine works better and is safer.
Summary written for real people, not researchers, by Clin2.

Other trials that look related to this one.
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.
This study compares two ways to remove bladder stones without open surgery. Both methods use a small camera and tools inserted through the body (either through the urethra or through a tiny skin opening), and the goal is to see which is safer and more effective for adults.
This trial tests two different doses of medications (tamsulosin and tadalafil) to help with pain and discomfort from a plastic tube (called a DJ stent) placed in your kidney after stone removal surgery. The goal is to find which dose combination works best and is safest.
This study compares two minimally invasive procedures to remove small-to-medium kidney stones (1 to 2.5 cm). The goal is to see which method is safer and more effective, possibly leading to quicker recovery and fewer side effects.
This study tests whether taking tadalafil (at 2.5 mg or 5 mg) along with tamsulosin is better for treating urinary symptoms caused by an enlarged prostate than taking tamsulosin alone. It aims to find the best dose combination to improve your quality of life.
This study compares two ways to remove kidney stones: mini-PCNL (a small incision in your back) versus flexible ureteroscopy with a suction sheath (a tube through the urinary tract). It aims to find which method works better and is safer for stones of this size.
