Introduction: Renal calculi is one of the oldest disease. Kidney stones result from precipitation of substances within the urine. Multifactorial causes of Urolithiasis and diversity of current treatments complicate clinical management of patients and offer opportunities for fruitful research.

Materials & methods: Prospective observational study on patients with history, clinical & radiological features suggestive of renal colic were included in the study. Prestructured proforma was filled and relevant blood investigations were noted. Treatment was given case by case basis.

Results: Of 218 patients, 162 were male and 56 female. Renal colic was commonly observed in age group 20–30 (30.27%). 210 patients had mixed type of diet with 198 patients taking <3 litres of daily intake of water. Pain in the abdomen was the most common symptom present. Serum calcium levels were >9 in 128(58.71%) patients. Phosphorous and uric acid level were normal in the majority of patients. 78.0% cases were managed conservatively.

Conclusion: The demographic factors and the etiological factors associated with renal stone could be identified. Less water intake, mixed diet, raised serum calcium levels are commonly associated with renal colic.
