Transforming Urological Stone Removal with the Patented ClearPetra Ureteral Access Sheath

The innovative ureteral access sheath known as ClearPetra is changing the game when it comes to stone removal treatments. There are several ways in which this cutting-edge tool might enhance the efficacy and security of the treatment.

Eliminating the Need for Additional Accessories

One of the standout features of the ClearPetra ureteral access sheath is its ability to eliminate the need for additional accessory devices during stone removal procedures. Traditionally, healthcare professionals have relied on a stone basket, forceps, and an anti-retropulsion device to effectively capture and extract stone fragments. However, with the ClearPetra ureteral access sheath, these accessory devices are no longer necessary, as the stone fragments are aspirated out spontaneously.

Enhanced Intra-Luminal Control and Evacuation

The ClearPetra ureteral access sheath features a 45° oblique branch that can be connected to a suction apparatus. This innovative design allows healthcare professionals to actively and easily control the intra-renal pressure (IRP) without compromising the visual field. Moreover, the suction mechanism enables the simple and effective evacuation of stone fragments, thereby shortening the overall operation time.

Maintaining Optimal Intra-Luminal Conditions

The ClearPetra ureteral access sheath is designed to create a vortex through continuous irrigation and aspiration. This mechanism ensures that the irrigated fluid can be effectively evacuated, thereby consistently maintaining low intra-renal pressure and temperature. This is a crucial advantage, as it helps to minimize the risk of complications and thermal damage, which can occur during traditional stone removal procedures.

Seamless Integration with Existing Procedures

The ClearPetra ureteral access sheath is compatible with a wide range of existing urological procedures, including percutaneous nephrolithotomy (PCNL) and ureteroscopy. This seamless integration enables healthcare professionals to incorporate the ClearPetra sheath into their established workflows, without the need for significant changes or additional training.


The ClearPetra Ureteral Access Sheath changes stone removal. The ClearPetra sheath streamlines therapy and improves patient outcomes by eliminating the need for supplementary devices, improving intra-luminal control and evacuation, and maintaining ideal conditions. ClearPetra stands to revolutionize stone removal in modern urology as a versatile and revolutionary equipment.
