Recurrent stone formers-metabolic evaluation: a must investigation

Abstract

Background: The lifetime prevalence of kidney stone disease is estimated at 1% to 15% and the mean rate of recurrence of stone is estimated to be 30% at 5 years, 50% at 10 years and 80% at 20 years. Symptomatic urinary calculus can cause considerable discomfort to the patient. The aim of the study was to evaluate the various serum and urinary parameters. Methods: 50 patients with history of renal stones coming to SGRDIMSR were evaluated for various serum and urinary parameters. Results: Serum calcium, sodium, phosphorus, potassium, B. urea, S. creatinine is higher than normal in patients with recurrent renal calculi. Most of the urinary parameters were also similar to studies stating that they have a pivotal role in recurrent stone formers. Conclusions: For the frequent stone formers and even for some first time stone formers interested in preventing future episodes of renal colic, a metabolic evaluation is necessary. Besides identifying the abnormality, the evaluation also helps determine the drug choices and dosages.
