Abstract


Background: Nephrolithiasis is the most common chronic kidney condition, is globally increasing in both sexes. Five main types of renal stones viz., calcium oxalate stones, calcium phosphate stones, uric acid stones, struvite stones and cystine stones. Purpose of the study is to evaluate various metabolic factors contributing to recurrent renal stone and determining appropriate medical treatment and diet modification to prevent recurrent renal stone disease.

Methods: This study was carried out in P.G. Department of Surgery, S.R.N. Hospital associated with M.L.N. Medical College, Allahabad. A total of 120 cases of recurrent renal calculi in and outpatient between August 2017 and July 2019 were included in the study. All patients were stone free at the time of metabolic urine evaluation.

Results: Most of the patients in the study were in the age 21 to 50 years. 80% were males and 20% were females. In 24-hour urine analysis most common metabolic abnormality seems to be hyperoxaluria (92.5%) followed by hypercalciuria (82.5%), high pH (67.5%), and least common seems to be hypocitraturia (15%), followed by hyperphosphaturia (20%), hypernatreturia (25%), and low level of potassium (25%).

Conclusions: All patient of recurrent stone formation are advised increase fluid intake. In patient with hypercalciuria and hypocitraturia, dietary restriction of protein, oxalate and sodium, treatment includes thiazides supplemented with potassium citrate. In patient with hyperoxaluria dietary restriction of oxalate rich food and in hyperuricosuria dietary restriction of animal protein is advised.
