The Impact of Nutritional Service in the Stone Clinic on the Patient Urine Collection Results

Study Overview
=================
Brief Summary
-----------------
Kidney stone disease has become a common phenomenon in the US and Europe with a growing incidence of about 10%. Life style and dietary changes have a cardinal part in kidney stone prevention. Therefore it was only natural to determine the impact of the addition of a nutritionist to a stone clinic run by a urologist and a nephrologist.

Detailed Description
-----------------
Kidney stone disease has become a common phenomenon in the US and Europe with a growing incidence of about 10%. A history of kidney stone disease has also been connected to cardiovascular and renal insufficiency events to a point that kidney stones is looked at today as a systemic predictor of hypertension, cardiovascular disease and more. Seeing the importance of these risk factors we initiated a stone clinic for our kidney stone patients several years ago run jointly by a urologist and a nephrologist. Seeing that life style and dietary changes have a cardinal part in kidney stone prevention, it was only natural to determine the impact of the addition of a nutritionist to a stone clinic run by a urologist and a nephrologist on our patient parameters.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Test group<br>100 Patients that were referred to our stone clinic for follow up with risk factors for stone recurrence like metabolic syndrome and diabetes, uric acid stones etc. In addition to seeing our urologist and nephrologist these patients will also be referred to a nutritionist in order to balance risk factors and will be followed for one year with our usual blood tests and imaging | Behavioral: Dietary recommendations<br>* The test group will be seen by a nutritionist and will receive specific dietary recommendations according to their specific comorbidities and drugs<br>|
| Control group<br>100 Patients that were referred to our stone clinic for follow up without risk factors for stone recurrence will see our urologist and nephrologist and will be followed for one year with our usual blood tests and imaging | |
