Adherence to Fluid Intake Recommendations in Kidney Stone Patients

Adherence to Fluid Intake Recommendations After Stone Removal in Low Risk Group Patients

The cumulative risk of stone recurrence rate is up to 14% at 1 year, 35% at 5 years, and 52% at 10 years. Low urine volume caused by insufficient fluid consumption is one of the most crucial risk factors for kidney stone formation. According to the guidelines, a copious fluid intake to maintain a urine volume of at least 2.0 to 2.5 L/24 h is recommended for most kidney stone formers. Patients often find it difficult to follow the recommendations in fluid intake, which leads to stone recurrence. Therefore, there is a need to improve patient compliance and adherence to following the instructions on keeping water balance. For this purpose we developed a mixed educational program including two parts. The first is the mobile application called "StoneMD: Kidney Stones". The second is the "School for Patients" with kidney stones, which is responsible for the stone clinic effect.

The aim of the study is to test the hypothesis that using mixed educational program additionally to standard recommendations in patients after the first stone surgery episode helps to achieve better adherence to daily fluid intake recommendations than the using standard recommendations alone given at the day of discharge.

Inclusion Criteria:

• Low risk recurrence group patients;
• Patients after the first stone surgery;

Exclusion Criteria:

• Recurrent cases of stone formation;
• Patients, who do not have smartphones;
• Patients, who can't visit "Schools for Patients" with kidney stone disease;
