Investigating the Factors Relevant to Kidney Stone in Patients at Amir al-Muminin Hospital in Zabol City in 2017-2018
Background and purpose: Kidney stone is the most prevalent chronic kidney disease. The disease is widespread throughout the world and it is estimated that stones at 50% will have a relapse again within 10 years. Despite all the scientific advances in appropriate diagnosis and treatment of kidney stones, we observed high relapse rate, about 50%, within 5 years. In this study the relation between kidney stones formation with occupation, weight gain and age was investigated. Method: In this case-control study, 150 healthy individuals as control group and as treatment group 150 urinary tract stone patients from Amir al-Muminin Hospital of Zabol, that received definitive diagnosis on having stones, were recruited. Informational questionnaires about the disease were filled in through interviews with each patient under study. The information were collected and then coded and inserted into SPSS. T-test, Chi-Square test and Mann-Whitney test were used to calculate frequency, mean, and standard deviation of the variables in both control and treatment groups and to determine statistical differences between the different variables of the two groups. Findings: The average age of kidney stone patients were 12/60. The average age in control group were 11/3736/75. According to Independent Sample test the statistic difference between the patients and the control group was significant for age (p<0/05). In treatment group the highest frequency (36/7%) belonged to patients with high school diploma and in control group the highest frequency (61/3) belonged to those with associate degrees. Chi-Square test showed there was a significant difference between the two groups regarding the level of education (p<0/05) also there were significant differences between the two groups regarding their number of children and marital status (p<0/05). There were significant differences between the groups with regard to their gender, height, income and occupation (p<0/05). In treatment group the patients with overweight had the highest frequency value and in control group the highest frequency was for the patients with normal basal metabolic rate. The Independent Sample T-test showed a significant difference between the two groups concerning the basal metabolic rate. Conclusion: In general, the results of the study indicates that age, weight gain and basal metabolic rate, low education level, marital status and the number of children can be in line with kidney stone formation.
