Official Title: Randomized Double-blind Placebo-controlled Trial Assessing the Efficacy of Standard and Low Dose Hydrochlorothiazide Treatment in the Prevention of Recurrent Nephrolithiasis
Brief Summary:
The investigators plan to assess the efficacy of standard and low dose HCTZ treatment in the recurrence prevention of calcium-containing kidney stones. More specifically, the investigators aim to assess the dose-response relationship for three different dosages of HCTZ.
Study intervention: HCTZ 12.5 mg, 25 mg or 50 mg once daily per os for 24 or 36 months. In addition, all patients in HCTZ treatment arms will receive state-of-the-art non-pharmacologic recommendations for stone prevention according to current guidelines.
Control intervention: Placebo once daily per os for 24 to 36 months. In addition, all patients in the placebo arm will receive state-of-the-art non-pharmacologic recommendations for stone prevention according to current guidelines.
