Actual clinical practice pattern in SWL after COVID-19 era: a critical evaluation from different aspects

Abstract

To outline the current status of Shock Wave Lithotripsy (SWL) in stone treatment and the changes in the mode of application after the COVID-19 pandemic along with critical factors affecting the clinical practice of this particular procedure. This study targeted national and international urology experts who could share and contribute their experiences and perspectives on SWL practices after COVID-19 era. Approximately 650 urology specialists were invited to participate in the survey based study via Google Forms. Participation was voluntary and 398 of the invited participants completed the survey, yielding an acceptable response rate of approximately 61.23%. This survey highlights significant findings that shed light on the changes in clinical SWL applications. Nearly half of SWL procedures are performed by technicians or nurses instead of experienced urologists, potentially affecting the proper application and outcomes of the procedure. SWL seemed to be applied on a guideline (GL) indications based manner by the majority of the participants. Fluoroscopy remains still as the most commonly used method for radiological assessment, underscoring the necessity to teach sonography applications to younger urologists. Key reasons for the limited clinical application of SWL include the absence of lithotripters in the departments, high lithotriptor costs and significantly lower reimbursement rates compared to PNL and fURS modalities. Finally, an increase in SWL utilization rates has been observed post-COVID-19, highlighting its certain advantages realized during this period. These findings provide important insights into the role of SWL in stone treatment and the main factors influencing its clinical application practices. Although the popularity of SWL in the management of urinary stones is being stated to decline particularly in the last two decades, data obtained in this survey emphasized well that it is still a viable option especially for stones smaller than 15 mm. Our findings highlight the enduring relevance of SWL in contemporary stone therapy protocols in the context of COVID-19, where outpatient, non-invasive procedures are preferred. In addition to the consideration of certain factors affecting the rate of its application in clinical practice, to achieve high success rates with minimal complications in SWL, strategic patient selection and adherence to procedure guidelines seem to be crucial.
