MP22-22 - How Do Urologists Use Radiological Diagnostic Tools for Urinary Stone Disease Diagnosis: Evaluation of an Evaluation

Location: Room 252B

Introduction & Objective : Radiological diagnostic tools, especially computerized tomography (CT), have a prominent role in diagnosis and pre-operative planning of urinary stones. We aimed to investigate the preferences of urologists and urology-residents, about how and when they use these complicated tools while evaluating a stone patient.


Methods : A 22- item survey questionnaire was presented to the participants either printed or electronically through a web-based online system. The questionnaire was built in Turkish and was translated to English and French to facilitate contribution of urologists from different countries. Overall evaluation results were extracted and subgroup analyses were made. Results were compared according to the contributors' nationality as a Turkish and non-Turkish.


Results : A total of 222 urologists and urology-residents from 24 different countries (141 Turkish and 81 non-Turkish) participate to our study. Majority of the participants were found to be urologists (74.7%). The mean age was 39.1 ± 9.9. The vast majority of the participants (95.8%) preferred to evaluate the CT scans personally; and almost half of the participants (54.5%) absolutely asked radiology report of the CT prior to a surgery. The preferred mean CT section thickness of the study group were found to be 2.8 ± 1.44 mm. Subgroup analyses revealed that the rate of the participants who wanted to evaluate the CT images personally was higher in the Turkish compared to the non-Turkish group (p<0.001); and similarly Turkish participants asked for a radiology report less compared to the non-Turkish participants (p<0.001). Prior to a stone surgery non-contrast CT (NCCT) scan was the leading imaging technique preferred (77% for Turkish and 77.5% for non-Turkish). Intrestingly, Turkish participants were found to be in favour of intravenous pyelography (IVP) in kidney stone surgery work-up, whereas non-Turkish participants preferred contrast-enhanced CT scan. This difference in preference was shown to be statistically significant. Participants noted that they use various tools in NCCT scan evaluation, among these the most frequently used were found to be stone diameter (97.3%), stone-to-skin distance (86.9%), Hounsfield unit (79.3%) and infindibulopelvic angle measurements (77.9%).


Conclusions : Urologists and urology-residents usually prefer to have a radiology report for a NCCT scan before surgery; however, most of the urologists want to see and evaluate the NCCT personally. NCCT are frequently used to understand the stone characteristics and location. Radiologic work-up varies considerably between Turkish and non-Turkish urologists/urology-residents.
