Kidney stone analysis: an EAU section of urolithiasis (EULIS) survey on current practices and perspectives worldwide

To investigate the current thoughts and perspectives on kidney stone analysis amongst urologists and urology residents worldwide.

In October 2022 an online survey supported by the EULIS was circulated amongst urologists and urology residents worldwide. The survey was based on the current EAU guidelines regarding stone analysis and its role in urolithiasis management. Responses were collected until February 2023.

The survey was completed by 351 urologists (75.4%) and 115 urology residents (24.7%). 49.1% of the participants stated that performing kidney stone analysis was of utmost importance in every patient. 91.8% were of the opinion that stone analysis changes KSD management. 62.3% of the participants declared to adhere to the guidelines. 44.7% aim to perform stone analysis in first-time stone formers. 1 out of 11 does not send stones for kidney stone analysis at all. Urologists that pursued an additional endo-urology sub-specialism performed stone analysis more frequently compared to those who were not endo-urologists.

Although majority of urologists consider stone analysis an essential part of kidney stone management, in reality the practice patterns regarding stone analysis deviate from the EAU guidelines. Our aim should be to bridge the knowledge gap regarding stone analysis, foster collaboration to streamline logistics regarding stone analysis and enhance the quality of care we provide for kidney stone patients.
