NAFLD affects extrahepatic organs, including the cardiovascular and renal system. NAFLD was linked to an increased risk of future CVD and CKD events and a renal stone disease, which involves the deposition of crystals in the medulla and urinary tract, affects up to a third of the population in Asia. Nephrolithiasis is related to hypertension, asthma, chronic kidney failure, vitamin D deficiency, insulin resistance, fatal conditions, and coronary morbidity. Liver ultrasound is largely available and noninvasive for investigation of nonalcoholic fatty liver disease. In this study we hypothesized presence of kidney stones in the patients of nonalcoholic fatty liver independently from the Cardio vascular disease patients. Objective: To evaluate incidence of nephrolithiasis in the patients of nonalcoholic fatty liver disease. As a particular underlying risk factor, the relation between fatty liver and renal calculi has received little publicity. So we find out connection between fatty liver and renal calculi and explored in this study. Approach: 381 reports of Patients of nonalcoholic fatty liver disease who had undergone a transabdominal ultrasound scan were studied to rule out the presence of renal stones. Setting: Data was collected from private sector hospital Gujrat, Pakistan Results: 381 ultrasonography reports 167 (43.8%)of females and 214(56.2%) of males. Analysis shows incidence of 13.2% nephrolithiasis in females and 7.9% in males. Totally 10.2% in all 381 subjects. Conclusion: The study demonstrates that there is a 10.2% incidence of nephrolithiasis in the patients suffering from nonalcoholic fatty liver disease. There is high ratio in females than in males. All the data was analyzed by using Microsoft excel 365. Tables and graphs are used to demonstrate the results.
