Recurrent urolithiasis after surgery is considered as one of the global problems in surgery. Our aim is to see the benefit of high water intake, different diet regimes and drug treatment in the prevention of this problem. A prospective study of 3 years duration (1993-1995) was carried out in Sulaimania Teaching Hospital, surgical ward, including 100 patients having urolithiasis. Only triphosphate stones (56%) and calcium oxalate stones (44%) were found in our patients. Twenty percent had recurrent stones before, 32% had associated predisposing features, mainly UTI. Only 5% developed recurrence despite all measures of prevention, probably due to ignorance of the preventive measures beside working in hot whether and associated UTI. In conclusion, high water intake, diet and drug therapy can be an effective method for prevention of recurrent urolitiasis
