An innovative flexible ureteroscopy (URS) device enables urologists to operate the ureteroscope and basket simultaneously when retrieving kidney stones.

The Boston Scientific (Marlborough, MA, USA) LithoVue Empower Retrieval Deployment Device is an ambidextrous, physician-controlled stone retrieval system designed to turn a two-person task into a one-person operation, eliminating the possibility of potential miscommunication during stone basketing. The device seamlessly integrates with the Boston Scientific LithoVue Single-Use Digital ureteroscope and the Zero Tip, Dakota, Escape, and Graspit nitinol retrieval baskets.

A recent study by researchers at Johns Hopkins University (JHU; Baltimore, MD, USA) to evaluate the ergonomics of URS using single operator, dual operator, and LithoVue simulation models found that median procedure time was significantly improved when compared to single-surgeon URS (29.4 versus 51.3 seconds). In addition, average muscular work per second (AWS) was significantly improved to compared to single-surgeon URS, specifically in the thenar, flexor carpi ulnaris, and extensor carpi ulnaris muscles.

“The LithoVue Empower Device is a unique tool that can improve ureteroscopic stone treatment, as it puts the process of stone manipulation entirely into the hands of the surgeon,” said professor of urology Brian Matlaga, MD, of JHU, who presented the study at the 33rd EUS annual meeting. “Ultimately, the LithoVue Empower Device introduces a novel efficiency into ureteroscopic stone surgery, as it makes it simpler for the urologist to pick up and move a stone, a historic source of frustration for this procedure.”

“The LithoVue Empower Device was developed in direct response to a need to improve procedural bottlenecks during kidney stone removal procedures,” said David Pierce, executive VP and president of MedSurg at Boston Scientific. “We are committed to identifying and addressing unmet needs to enable healthcare providers to advance patient outcomes, reduce procedural costs, enhance quality of care, and evolve the treatment of urologic and pelvic conditions.”

Ureteroscopic stone manipulation and retrieval typically requires two experienced individuals: one to drive the ureteroscope and a second to manipulate the stone basket or grasper.
