- Abstract
Objectives: To evaluate the efficacy of the one‐surgeon basketing technique compared to the conventional two‐surgeon method for flexible ureteroscopy. Methods: Seven urologists (three trained and four less‐trained surgeons) extracted three renal stones using each technique with an off‐site simulator. We analyzed the task completion time, the number of times the basket forceps were opened and closed, and unexpected events during stone‐catching, for both techniques. Results: There was no significant difference in the total task completion time between the one‐surgeon (102.0 [interquartile range 63.5–164.0] s) and two‐surgeon (99.5 [interquartile range 75.0–145.3] s) techniques. However, the time it took the trained surgeons to extract all stones was significantly shorter with the one‐surgeon than with the two‐surgeon technique (19.0 [interquartile range 18.0–20.0] s vs 34.0 [interquartile range 25.0–40.0] s; P = 0.049). Among the less‐trained surgeons, the opposite effect was observed, but this difference was not statistically significant (96.5 [interquartile range 61.0–134.5] s vs 64.0 [interquartile range 51.5–77.0] s; P = 0.489). The number of times the forceps were opened and closed during stone‐catching was significantly lower with the one‐surgeon technique than with the two‐surgeon technique (5.0 [interquartile range 4.0–5.0] times vs 9.0 [interquartile range 6.0–14.5] times; P = 0.018). Conclusions: The one‐surgeon technique can offer comparable efficacy to the two‐surgeon technique. If surgeons are sufficiently trained, a one‐surgeon basketing technique for performing flexible ureteroscopy might become a new technical modality for extracting renal stones.
