Condition(s) targeted: Kidney Calculi

Intervention: Antioxidant group (Drug); Calcium Channel Blockers (Drug); Angiotensin receptor blocker group (Drug); Placebo (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Mansoura University

Official(s) and/or principal investigator(s):
Ahmed R. EL-Nahas, MD, Principal Investigator, Affiliation: Mansoura University

Summary

This study will be conducted to evaluate the protective effects and mechanisms of antioxidants (vitamins A, C, E and Selenium), calcium channel blocker (Verapamil) and angiotensin receptor blocker (Lozartan) against shock wave induced renal injuries.

Clinical Details

Official title: A Randomized Controlled Trial for Evaluating Protective Effects of Antioxidants (Selenium and Vitamins A, C and E), Calcium Channel Blocker (Verapamil) and Angiotensin Receptor Blocker (Losartan) Against Extracorporeal Shockwaves Lithotripsy Induced Renal Injury

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Prevention

Primary outcome: Renal damage

Secondary outcome: The mechanisms of renal protection

Detailed description: The protective effect will be evaluated via estimation of the changes in renal tubular enzyme (NGAL) and detection of albumen levels in urine. The mechanisms of protection will be investigated by estimation of renal perfusion and functional changes using dynamic MRI.

Eligibility
