“…Interestingly, these trends were not observed among urologists who were skilled in ureteroscopic manipulation, but were more pronounced in residents. Recently, an interesting simulator-based study using motion capture showed that ureteroscopic e ciency in f-URS was correlated with head and torso movement [19]. If su cient ureteroscopic manipulation cannot be achieved by wrist rotation alone, elbows, shoulders, and the torso should be moved to represent them.…”

When performing flexible ureteroscopic lithotripsy for upper urinary stones, an important treatment option is stone extraction. In this study, we aim to investigate the surgical factors affecting the efficiency of stone extraction and surgeon stress using a flexible ureteroscopic lithotripsy simulator model. This simulator-based study involved 16 participants: eight urologists and eight residents. Participants each performed two tasks eight times, with two types of ureteral access sheath (Flexor or Navigator), with or without M-arm, and with left or right kidney models. Task1 was to touch each renal calix with the ureteroscope, and Task2 was to extract stones. The recorded outcomes of this study were the number of times that the ureteroscope got stuck during insertion, the number of times a stone was dropped during removal, the number of times the basket forceps were opened and closed, and the time required to accomplish each task. The number of times that the ureteroscope got stuck was significantly higher when Navigator was used compared with Flexor overall, and for urologists and residents (all P < 0.01). The number of times a stone was dropped was significantly higher in the ipsilateral group than in the contralateral group overall (P = 0.01), and the number of times the basket forceps were opened and closed was significantly higher in the ipsilateral group than in the contralateral group both overall and for residents (all P < 0.01). Differences in ureteral access sheath and the kidney side were surgical factors affecting the efficiency of stone extraction during flexible ureteroscopic lithotripsy with the one-surgeon basketing technique.

“…Through surgical videos, several studies have leveraged machine learning models to accurately assess technical skills [41 ▪▪ ,42]. Kinematic data has also been used to assess surgical performance, majorly to represent efficiency [43,44]. Besides directly recording kinematics from surgical instruments, kinematics can also be extracted from surgical videos [45].…”

Purpose of review This review outlines recent innovations in simulation technology as it applies to urology. It is essential for the next generation of urologists to attain a solid foundation of technical and nontechnical skills, and simulation technology provides a variety of safe, controlled environments to acquire this baseline knowledge. Recent findings With a focus on urology, this review first outlines the evidence to support surgical simulation, then discusses the strides being made in the development of 3D-printed models for surgical skill training and preoperative planning, virtual reality models for different urologic procedures, surgical skill assessment for simulation, and integration of simulation into urology residency curricula. Summary Simulation continues to be an integral part of the journey towards the mastery of skills necessary for becoming an expert urologist. Clinicians and researchers should consider how to further incorporate simulation technology into residency training and help future generations of urologists throughout their career.
