dc.description.abstract	Kidneys are among our most vital organs as they filter toxins and produce essential chemicals in our bodies. Kidney stones are often very painful, and can keep happening in some people. When the kidneys stop functioning properly our body becomes toxic and we cannot survive. Chronic Kidney Disease is a dangerous medical condition characterized by a gradual loss of kidney function over time, which if left untreated can then lead to Chronic Renal Failure (CRF). Once you have reached end-stage chronic renal failure you have two options dialysis for the rest of your life, or a kidney transplant.The objective of this study is to investigate a competing risk model of recurrence time for kidney stone disease after surgery with the consideration of various factors.The study analyzed a competing risk model for recurrence of kidney stone disease after surgery competed by death. A total of 193 patients were taken for this study, which had removal of the disease by surgical. Sub hazard plots of the events and competing risk models of each event separately used to explore the major risk factors and covariates for the recurrence and death rates of a patient in Bahir Dar FelegeHiwotsurgical ward.Based on median time of each even type,the median death time was 6days, the median recurrence and median censor time was 6days. According to sub hazardratiosfor recurrence event hazard the hazard for urban residentswas about 72% higher than rural residents with 95% confidence interval (1.640, 3.058), the hazard of recurrence for out of office workers was around two times than the hazard of unemployed patients with 95% confidence interval (1.960, 4.258) and also the hazard of recurrence for in office (civil servants) was around 63% less than the hazard of unemployed patientswith confidence interval (.117, .441), the hazard of recurrence for patients who smoked cigarette was about 6.7% higher than nonsmokers with confidence interval (1.032, 3.563).According to our findings, place of residence had been found a significant effect on the recurrence of kidney stone disease after it removed by surgery on kidney stone patients. Our finding shown that the urban residents had higher hazard of recurrence the disease compared with rural resident patients.According to patient’s history of diabetes, diabetic patients had higher hazard of recurrence than non-diabetic patients	en_US
