• Aminophylline in the Bladder to Help Place a Ureteral Stent Quickly

  This study tests whether putting aminophylline into the bladder before stenting helps adults with acute kidney blockage due to stones see if a ureteral stent can be placed more easily and quickly.

  Recruiting Phase 2 Beni-Suef University · Banī Suwayf, Beni Suweif Governorate · NCT07617948

• Melatonin and Solifenacin for stent-related symptoms after ureteroscopy

  Recruiting Phase 2 Beni-Suef University · Banī Suwayf, BeniSuef · NCT07617922

• L-Citrulline vs Tamsulosin for Helping Distal Ureteral Stones Pass

  This study tests whether L-citrulline helps stones pass from the distal ureter as well as or better than tamsulosin in adults with a single 5–10 mm stone.

• Intravesical aminophylline to aid ureteroscopic access in children with distal ureteral stones

  This study tests whether putting aminophylline in the bladder helps some kids get a semi-rigid ureteroscope to pass into the ureter during treatment for distal ureteral stones.

  Recruiting Phase 2 Beni-Suef University · Banī Suwayf, Beni Suweif Governorate · NCT07617896

• Mirabegron vs. Tamsulosin for ureteral stone expulsion

  This trial tests four approaches—Mirabegron alone, Tamsulosin alone, both together, or standard care—to help adults with a ureteral stone pass the stone within about a month.
