Abstract: Renal stone is a significant health problem all over the world. Aim: This study aimed to evaluate the effect of selfmanagement protocol on dietary adherence for patients with kidney stones undergoing Shock Wave Lithotripsy Technique. Design: A quasi experimental design was used. Setting: This study was performed in the shock wave lithotripsy unit of the Urology Outpatient Clinic affiliated with the Zagazig University Hospital . Sample: A Purposive sample of 100 patients , 50 randomly allocated to each group (study and control). Tools: Patients' interview questionnaire, Self- management practices, perceived dietary adherence questionnaire, and barriers towards consuming a healthy diet. Results: More than two thirds (70.0%) of patients in the study group adhered to diet post program, while most (92.0%) of the patients in control group were not adherent. There was a highly statistically significant difference between study and control groups post implementation of self - management protocol regarding total knowledge, attitude, practice of fluid drink, and total practice regarding food at p < 0.001. Conclusion: According to study findings the level of knowledge, attitude, practice of fluids consumption, and practice regarding food consumption of the patients in the study group significantly improved after the intervention compared to before the intervention. There was a positive correlation between knowledge ,practice ,attitude ,and among the patients in study group, which supported the stated hypothesis. Recommendations: Additional study on larger probability sample is recommended for general capacity and wider use of self-care practices.
