Official Title: Effect of Tamsulosin and Nifedipine on the Elimination of Fragments After Extracorporeal Shock Waves Lithotripsy in Patients With Kidney Stones - a Prospective, Double-bli
Brief Summary: The investigators objective is to study if some drugs can improve the success rate of extracorporeal shockwave lithotripsy for renal stones.
Detailed Summary: Extracorporeal shockwave lithotripsy is one of the modalities of treatment of renal stones. It´s a machine that breaks the renal stones extracorporeally. Some drugs, like alpha blockers and calcium channel blockers, can improve the success rates of this procedure. Our objective is to study the real effects of two drugs, tamsulosin and nifedipine, compared to placebo, in the elimination of fragments after the extracorporeal shockwave lithotripsy treatment.
Sponsor: University of Sao Paulo General Hospital
Current Primary Outcome: To evaluate the effects of Tamsulosin and Nifedipine in the success rates after treatment of radiopaque renal stones between 5-20 mm with only one session of SWL [ Time Frame: 30 days ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- To evaluate the effects of Tamsulosin and Nifedipine in the episodes of pain after treatment of radiopaque renal stones between 5-20 mm with only one session of SWL [ Time Frame: 30 days ]
- To evaluate the effects of Tamsulosin and Nifedipine in the velocity of elimination of fragments after treatment of radiopaque renal stones between 5-20 mm with only one session of SWL [ Time Frame: 30 days ]
Original Secondary Outcome: Same as current
