Intra-Renal Pressure (IRP) Monitoring Ecosystem with Intelligent UAS
Seeing the Invisible. Protecting the Kidney.
Intrarenal pressure (IRP) plays a critical role in every Retrograde Intrarenal Surgery (RIRS).
When IRP is too high, the risk of pyelovenous backflow, infection, and renal damage increases — but traditionally, IRP has been invisible.
With YiGao’s Elephant series and the Tidor Intelligent Pressure Control System, IRP can now be monitored, displayed and managed in real time — turning RIRS into a safer and more predictable procedure.
Pro Element Technology brings this complete IRP ecosystem to hospitals and urologists in Malaysia.

Why IRP Matters in RIRS
During RIRS, intrarenal pressure fluctuates due to:
• Irrigation flow and pressure
• Ureteral access sheath size and design
• Outflow and suction efficiency
• Stone burden and laser energy
• Working space and scope diameter
Uncontrolled pressure may contribute to:
• Pyelovenous and pyelolymphatic backflow
• Post-operative infection and sepsis
• Increased bleeding and poorer visibility
• Longer operative time and higher complication risk
Monitoring IRP in real time helps the surgical team:
• Recognise pressure spikes early
• Adjust irrigation and suction proactively
• Perform RIRS more confidently and consistently

Our IRP Ecosystem
We offer a stepwise solution so each centre can adopt IRP monitoring according to its needs, workflow and budget.
Suction-Enabled UAS (without IRP sensor)
Elephant II is ideal for centres starting their journey in pressure management.
• Suction-enabled ureteral access sheath
• Enhances outflow and visibility
• Supports more efficient stone fragment evacuation
• Can be connected to the Tidor system for controlled suction and irrigation
• No IRP sensor – does not display or transmit pressure values
Perfect for centres that want the benefits of suction RIRS, with the option to upgrade later to full IRP monitoring.

2. YiGao Elephant III
Suction UAS with IRP Sensor & External Reusable Controller
Elephant III adds true IRP monitoring to suction RIRS.
• Suction-enabled UAS with built-in IRP sensor near the tip
• Connects to the Tidor Intelligent Pressure Control System for real-time IRP display
• Comes with a reusable external controller, helping reduce long-term cost
• Allows surgeons to adjust irrigation and suction based on live pressure readings
An excellent balance between technology, safety and cost for high-volume RIRS centres.

3. YiGao Elephant IV
All-in-One Intelligent UAS with Integrated Controller
Elephant IV is designed for centres that want a fully integrated, plug-and-play solution.
• Suction-enabled UAS with built-in IRP sensor
• Integrated controller – no separate external controller required
• Direct, simple connection to the Tidor IRP system
• Streamlined setup and quick learning curve for the OR team
For hospitals targeting a fully digital and standardised RIRS workflow, Elephant IV offers the most complete solution.

4. YiGao Tidor Intelligent Pressure Control System
The Heart of IRP Monitoring
The Tidor system links the Elephant sheaths with the surgical team, providing live intrarenal pressure information and intelligent flow management.
Key Functions
• Real-time IRP monitoring and display
• Adjustable irrigation pressure and flow
• Suction control (with compatible Elephant sheaths)
• Audible and visual pressure alerts
• Supports consistent, reproducible RIRS technique across surgeons
Clinical Benefits
• Better control of IRP during laser lithotripsy
• Improved visibility in the collecting system
• Reduced risk of backflow-related complications
• Potential reduction in post-operative infection risk
• More predictable operative course and standardised outcomes

Working Together: The Pressure Ecosystem
When combined, the Elephant UAS and Tidor system create a comprehensive pressure ecosystem for RIRS:
• Elephant II – Suction and improved outflow, ideal starting point
• Elephant III – Suction + IRP sensor + reusable controller
• Elephant IV – Integrated, intelligent UAS with built-in controller
• Tidor System – Central platform for IRP monitoring and flow control
This ecosystem allows each centre to move step-by-step:
From “no pressure awareness” → suction RIRS → real-time IRP monitoring → fully intelligent pressure-guided surgery.
