DYNE Medical Group Unveils Next-Generation Single-Use Flexible Ureteroscope ‘URUS 2.0’ at KSER 2026
Featuring a 4.0 Fr working channel and Smile Digital Tip, the device is designed to enhance irrigation and imaging performance in FANS-assisted procedures
DYNE Medical Group announced on July 23 that it unveiled its next-generation single-use flexible ureteroscope, URUS 2.0, for the first time at KSER 2026, recently held at BEXCO in Busan.

During the event, the company showcased URUS 2.0 at its booth and introduced the device’s newly applied structural features and key specifications. The exhibition particularly highlighted the product’s improved irrigation performance, focusing on the balance between irrigation and suction flow, which is becoming increasingly important in retrograde intrarenal surgery, or RIRS.
In recent RIRS procedures, the use of Flexible and Navigable Suction Ureteral Access Sheaths, commonly known as FANS, has been expanding. As a result, maintaining sufficient irrigation while ensuring stable suction flow has emerged as an important procedural consideration.
Because FANS systems continuously suction irrigation fluid and fragmented stone debris, a sufficient and consistent supply of irrigation fluid must be delivered through the endoscope. Accordingly, not only suction performance but also an endoscope structure capable of maintaining irrigation flow while surgical instruments, such as laser fibers, are inserted has become increasingly important.
To address these procedural requirements, URUS 2.0 features an enlarged working channel, increased from 3.6 Fr in the previous model to 4.0 Fr. The expanded internal space is designed to maintain sufficient irrigation flow even when surgical instruments are inserted.

The distal end of the device incorporates the Smile Digital Tip, which is differentiated from conventional circular outlets and straight-edged distal-tip designs. While the 4.0 Fr working channel provides a pathway for increased irrigation flow, the Smile Digital Tip is structured to distribute the supplied irrigation fluid across a wider area rather than concentrating it in a single direction.
In a fluid-dynamics experiment conducted by DYNE Medical Group’s clinical team in collaboration with researchers from Seoul National University Hospital, the semicircular outlet demonstrated a wider lateral expansion of the irrigation jet near the outlet compared with a conventional circular outlet. The results indicate that the Smile Digital Tip distributes irrigation fluid over a broader area instead of concentrating it at a narrow point.

This flow pattern may help reduce stone retropulsion during laser lithotripsy by mitigating the concentration of irrigation force at a specific point. The potential effects of this structure on stone-fragment movement and removal are currently being evaluated through follow-up studies.
URUS 2.0 also offers improved imaging performance. Camera resolution has been upgraded from 320 × 320 to 720 × 720, while an exposure-control function has been introduced to reduce excessive light saturation in bright areas. These improvements are intended to provide a clearer visual field during surgery.
The 6 o’clock working-channel configuration, a key feature of the previous URUS 1.0 model, has also been retained in URUS 2.0. The configuration allows the laser fiber to appear at the lower center of the endoscopic image, enabling surgeons to position the stone in the center of the screen while maintaining a balanced view of both sides.
The design is also intended to facilitate more precise targeting of stones located in the lower calyx.

The advantages of the 6 o’clock working-channel configuration were also presented during a live surgery session held at the event. Professor Hae-do Jeong of Inje University Ilsan Paik Hospital performed a live procedure using URUS 1.0, which features the 6 o’clock working channel, demonstrating its targeting characteristics and accessibility to the lower calyx in an actual surgical setting.
During the live surgery, procedures were performed simultaneously on two patients with similar stone burdens. The operation performed using the device with the 6 o’clock working-channel configuration was completed earlier than the procedure performed using an endoscope with a 3 o’clock or 9 o’clock working-channel configuration.
This prompted meaningful questions and discussion among the on-site panelists regarding whether the precise targeting characteristics of the 6 o’clock working channel may have contributed to the difference in procedure time.
A representative of DYNE Medical Group said, “In recent RIRS procedures, not only image quality but also the balance between irrigation and suction flow has emerged as an important factor in supporting procedural safety, particularly in terms of managing intrarenal pressure and temperature.”
The representative added, “URUS 2.0 is designed to increase irrigation flow through its 4.0 Fr working channel and distribute irrigation fluid over a wider area through the Smile Digital Tip, thereby supporting balanced irrigation and suction flow in FANS-assisted procedures.”
“With its enhanced imaging performance and stable fluid-flow characteristics, we expect URUS 2.0 to contribute to improved procedural efficiency and safety,” the representative emphasized.
Meanwhile, URUS 2.0 is currently undergoing the domestic regulatory approval process with Korea’s Ministry of Food and Drug Safety. DYNE Medical Group plans to officially launch the product and begin related product-training and academic activities once regulatory approval is completed, which is expected around the end of September.
