Research Project: Pilot Study on Oral Urea Use in Patients at High Risk of Kidney Stone Recurrence

Phase 2
Withdrawn
Conditions
Kidney Stone
Interventions
Drug: Ure-Na
Registration Number
NCT04727606
Lead Sponsor
Centre hospitalier de l'Université de Montréal (CHUM)
Brief Summary

In clinical practice, many patients are not able to modify their habits to achieve a high level of diuresis and fluid intake and therefore are at an elevated risk for stone recurrence.

The investigators think that Ure-Na (osmotic agent) taking could help to increase urine volume and decrease urine concentration, which would be of benefit in the prevention of kidney stones.
