Objectives: The European Society of Urological Technology (ESUT) conducted a survey in order to assess and record the current trends between urologists with regard to the application of endourological stone management to identify trends and differences in treatment strategies among urologists.
Methods: A total of 695 certified urologists and urological residents answered the ESUT Endourological Stone Management Questionnaire. There were 136 (28.7%) chief urologists, 240 (50.6%) staff urologists and 98 (20.7%) residents. The respondents were classified according to both the geographical origin (in four groups: Northern Europe (NE), Southern Europe (SE), Eastern Europe (EE) and Outside Europe (OE)), and department size (number of urological beds per department: small < or = 25, medium 26-50 beds, large > 50 beds) in order to identify any differences in the replies.
Results: On average, 40.1 newly diagnosed patients and 73.6 revisits with urolithiasis are seen a month per department. According to the replies, there are no significant differences in total numbers of treatments in ESWL and/or endourological stone managements amongst the geographically based groups. Monthly, on average 68.5 ESWL treatments and 23.0 URS are performed per department. A significant majority of surveyed urologists performs URS with a rigid or semi-rigid instrument (79%) instead of a flexible instrument (21%, p = 0.003). URS is more frequently performed outside Europe (p = 0.02) with a more frequent use of dormia catheters (p < 0.001). On average, 20.9 double g-stents are placed monthly in each department, most commonly before or after endourological procedures (p < 0.001). Percutaneous procedures are performed by 69.6% of the respondents with a mean of 16.8 PNL procedures a month. PNL for stone management is mainly performed in Eastern Europe and non-European countries (p = 0.017). Nephrostomy tubes are used by 77.7% of the responding urologists. Monthly, 13.1 nephrostomy tubes are placed, mostly during PNL or after endourological procedures (40.7%).
Conclusion: The data obtained from the 695 urologists and residents provides information on the performed procedures and the use of material. In general, respondents from different geographical locations perform similar procedures and use identical material; however URS and PNL are performed more frequently outside of Europe, whereas laser lithotripsy is frequently used in Northern European counties.
