Are the prevalence of nephrolithiasis and high salt intake preferance associated?

Abstract EN

BACKGROUND : 75%of all renal stones are composed of Calcium salts.

Sodium renal excretion augment renal Calcium excretion.

In males with recurrent Calcium oxalate stones and Hypercalciuria, restricted intake of animal protein and salt combined with normal Calcium intake provides greater protection than the traditional low Calcium intake; but this is difficult to accomplish because salt intake enhance the taste of food to many people.

AIM OF STUDY : To study any statistically significant correlation between prevalence of nephrolithiasis and high salt intake preference compared to patients having other than nephrolithiasis.

PATIENTS AND METHODS : This is a case controlled, screening retrospective study of 274 patients accomplished abdominal U\S at University Hospital in Al-Diwania city, from 9 \ 15\07-1\15\0for a variety of reasons ;divided into those with +ve Nephrolithiasis (80 patients) and those without Nephrolithiasis (194 patients).

All were interviewed by a verbal questioner about preference and consumption of HIS in their usual home made daily meals.

Both groups were matched to age and residence.

The results showed 54 patients from +ve Nephrolithiasis group prefer and consume HSI, while 26 patients don’t ; compared to 8 patients from -ve Nephrolithiasis group prefer and consume HSI, while 187 don’t; with P value <0.001.

This strong correlation still presents after controlling sex , but not family clustering.

CONCUSIONS: Preference and consumption of HSI is strongly correlated to increased risk of Nephrolithiasis, even after controlling male sex but not family clustering.
