Abstract
Background: Extracorporeal shockwave lithotripsy is one of the outpatient procedures that are used to fragment a kidney or ureteric stone into small pieces to help them to pass through the urinary tract without blocking the ureter.
Aim of the work: Assessment of extracorporeal shockwave lithotripsy (ESWL) in the management of renal stones in relation to different sizes and locations of the stone.
Objectives: To identify the success rate of ESWL in treatment of renal stones according to stone size and location and compare it with untreated ureteric stones.
Method: Retrospective cohort study between 2014 and 2018 carried out by obtaining data from electronic health records and patients' files for all patients who had ESWL in King Abdulaziz Medical City, Jeddah. Analysis was done for multivariables such as stone size, complications, number of sessions used and the need for other procedures. The collected data were analyzed by computer using Statistical Package for Social Science (version 20, SPSS Inc., Chicago, IL).
Results: This study included 88 patients, 64.7% were males and 35.3% were females who complained of having stones. These patients had 124 stones (79 kidney stones and 45 ureteric stones) out of them 67 (54.03%) subjects who went for 1 session, 31 (25%) subjects who went for 2 sessions and 26 (20.97%) subjects who went for 3 sessions. The overall success rate of ESWL was 41.13%, out of 45 subjects who had ureteric stones; 18 (35.29%) subjects had a successful ESWL.
Conclusion: Future researchers should consider investigating the impact of other factors dually such as success rate, and the following parameters: BMI with age, BMI with gender, BMI with size of the stone, age with gender, age with size of the stone, gender with size of the stone.
