ABSTRACT
INTRODUCTION:
Previous studies have shown that prestenting in ureterorenoscopic stone removal (URS) is carried out more frequently in Germany than in other countries.OBJECTIVE:
This investigation evaluated the impact of high prestenting rates on outcomes as well as the influence of stone characteristics and treatment habits on prestenting.METHODS:
The dataset from the BUSTER observational study was used. Patient and stone characteristics, as well as treatment outcomes, were analyzed for 307 cases from 14 urological clinics in Germany.RESULTS:
The overall prestenting rate was 70.0%. Prestenting rates were significantly higher for renal stones than ureteric stones (84.6 vs. 60.6%, p < 0.0001). Compared to the unstented cases, prestenting for renal stones improved stone-free rates (73.2 vs. 11.1%, p < 0.0001) and increased the rate of completely lesion-free URS (45.4 vs. 16.7%, p = 0.034) while reducing the rate of poststenting (from 100 to 80.8%, p = 0.041). None of these effects could be demonstrated when prestenting for ureteric stones. Prestenting rates were less variable for renal stones (57-100%) than for ureteric stones (0-100%, p < 0.01).CONCLUSIONS:
This study confirms the benefits of prestenting in URS for renal stones but not for ureteric stones. There were considerable differences in prestenting rates between the participating clinics.Palabras clave
