Flexible and navigable suction access sheaths: what size stone particles can be cleared?

BJU International, Volume 137, Issue S3, Page S71-S77, March 2026.
Objectives To perform benchtop experiments on flexible and navigable suction (FANS) ureteric access sheaths (UASs) to determine the clearance capabilities for various stone sizes when paired with different‐sized ureteroscopes. Methods Quartz stones were used as a surrogate for renal stones.

Practice patterns of ureteral access sheath during ureteroscopy for nephrolithiasis: a survey among endourologists worldwide

BMC Urology, 2019
Background The use of ureteral access sheath (UAS) during ureteroscopy is controversial. We aimed to explore practice patterns of UAS during ureteroscopy for nephrolithiasis among endourologists worldwide.

Ureteral Access Sheath Influence on the Ureteral Wall Evaluated by Cyclooxygenase-2 and Tumor Necrosis Factor-a in a Porcine Model [PDF]

, 2017
Objective: To examine the effect of ureteral access sheath (UAS) on the expression of the pro-inflammatory mediators cyclooxygenase-2 (COX-2) and tumor necrosis factor-α (TNF-α) in the ureteral wall.

Experimental stone clearance with in‐scope suction and flexible and navigable suction access sheaths

BJU International, Volume 137, Issue S3, Page S45-S52, March 2026.
Objective To perform benchtop experiments using direct in‐scope suction (DISS) ureteroscopes (Pusen Medical, Zhuhai, China; 3.6‐Ch and 5.1‐Ch working channels) and flexible and navigable suction (FANS) ureteric access sheaths (ClearPetra; Wellead, Guangzhou, China) to establish their ability to clear stones of different diameters.

Flexible and navigable suction access sheaths: balancing sheath and scope size for desired flows

BJU International, Volume 137, Issue S3, Page S60-S70, March 2026.
Objective To study the effects of ureteroscope diameter, ‘flexible and navigable suction’ access sheaths (FANS) diameter, and irrigation pressure on intrarenal pressure (IRP) and irrigation fluid flow rates in ex vivo porcine kidneys; these benchtop data were compared against mathematical modelling results.

Direct in‐scope suction (DISS) ureteroscopy: techniques, outcomes and future directions

BJU International, Volume 137, Issue S3, Page S19-S28, March 2026.
Objective To provide an overview of direct in‐scope suction (DISS) ureteroscopy, an emerging technology that integrates suction directly into the ureteroscope with the aim of enhancing stone clearance, improving visualisation, and reducing intrarenal pressure during ureteroscopic stone surgery.

ASSIST‐U: A system for segmentation and image style transfer for ureteroscopy

Healthcare Technology Letters
Kidney stones require surgical removal when they grow too large to be broken up externally or to pass on their own. Upper tract urothelial carcinoma is also sometimes treated endoscopically in a similar procedure.
