• Nephrostomy Tract Infiltration to Ease Pain After Percutaneous Nephrolithotomy

  This trial tests whether injecting local anesthetic into the nephrostomy tract after PCNL helps reduce postoperative pain for adults undergoing the procedure.

  Recruiting Hitit University · Çorum, Çorum · NCT07721571

• Gentamicin Irrigation and Suction Ureteral Access in Kidney Stone Surgery

  This trial tests whether using gentamicin-containing irrigation fluid and a suction-enabled ureteral access sheath during retrograde intrarenal surgery (RIRS) can lower fever, SIRS, and sepsis after kidney stone treatment.

  Recruiting Hitit University · Çorum, Çorum and 1 other locations · NCT07655050

• Using a flexible suction sheath with flexible ureteroscopy for lower-pole kidney stones

  This trial will test whether adding a flexible, navigable suction sheath to flexible ureteroscopy helps adults with lower-pole kidney stones become stone-free more often and avoid repeat procedures.

  Recruiting Zagazig University · Zagazig · NCT07238803

• Investigating oxalate production in patients with calcium oxalate kidney stones

  This study is testing if people with calcium oxalate kidney stones produce more oxalate in their bodies than healthy individuals by following a special diet and taking certain supplements.

  Recruiting University of Alabama at Birmingham · Birmingham, Alabama and 1 other locations · NCT06989320

• Evaluation of a new system for breaking down urinary stones

  This study is testing a new system to see if it can safely break down urinary stones into smaller pieces, making it easier for people to pass them and feel less pain.

  Recruiting at 12 sites Avvio Medical · Phoenix, Arizona and 19 other locations · NCT06942949

• Vacuum-assisted vs conventional ureteral access sheath in modern kidney stone surgery

  This trial tests whether vacuum-assisted ureteral access sheaths improve stone removal and safety in retrograde intrarenal surgery for adults with kidney stones.

  Recruiting Namik Kemal University · Tekirdağ, Turkey · NCT06684756

• Superpulse thulium fiber versus holmium:YAG laser for breaking kidney and upper ureter stones during ureteroscopy

  This trial tests whether the superpulse thulium fiber laser works better than the holmium:YAG laser for adults (18–70) having ureteroscopy to break 6–20 mm kidney or upper ureter stones.

  Recruiting Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine · Shanghai, Shanghai Municipality · NCT06667557

• Investigating how the gut absorbs oxalate in kidney stone patients

  This study is trying to see if people with kidney stones absorb more oxalate from their diet than healthy individuals, which might lead to more oxalate in their urine.

  Recruiting at 2 sites University of Alabama at Birmingham · Birmingham, Alabama and 1 other locations · NCT06331546

• Using gut bacteria to reduce urinary oxalate in kidney stone patients

  This study is testing if introducing a specific gut bacteria can help adults with calcium oxalate kidney stones lower the amount of oxalate in their urine.
