Ureteral Access Sheath — 10/12/14 Fr × 35/45 cm
SKU: XY-UAS | Vaina de Acceso Ureteral — 10/12/14 Fr × 35/45 cm
The ureteral access sheath turns a series of ureteroscope passes into a single entry trauma: placed over a wire with its dilator, it stays as a stable channel from meatus to renal pelvis, and the scope enters and leaves as many times as the lithotripsy demands without renegotiating the ureter each pass. Its second job is less visible but equally cited: the annular space between sheath and scope drains irrigation continuously, keeping intrarenal pressure low through long procedures. Soft tip protecting the urothelium, kink-resistant body, low-friction surface. Sizes 10, 12 and 14 Fr in 35 cm (female, distal work) and 45 cm (male, high access). Size follows the ureteroscope: the inner passage must clear the scope with margin — send your fleet's model and we verify before manufacturing.

Frequently Asked Questions — Ureteral Access Sheath — 10/12/14 Fr × 35/45 cm
How is the size chosen?
By the ureteroscope passing inside: the sheath's inner passage must clear the scope's calibre with margin to slide and irrigate. A typical flexible scope asks for 12 Fr; fine scopes work in 10 and large-channel ones in 14. Send the exact fleet model when quoting — we verify compatibility before manufacturing, which beats discovering it in theatre.
What is the intrarenal pressure point about?
The scope's continuous irrigation raises renal pelvic pressure unless it has an outlet. The annular space between scope and sheath is that outlet: it drains continuously and pressure stays low throughout. That is the clinical-operational argument for the sheath in long procedures.
35 or 45 cm?
35 cm covers female anatomy and distal ureteric work; 45 cm high access in men. Most units order both in caseload ratio — same order.
What is the minimum order?
Size × length matrix consolidated. Documentation: technical file, ISO 13485, per-batch sterilisation; destination registration by the distributor.

One entry, many passes
Each basket run re-enters through the sheath instead of through the ureter. The entry trauma happens once; the passes stop counting.
The pressure argument
Continuous irrigation raises pelvic pressure unless it has an exit. The annulus between scope and sheath is that exit — the operational reason this sheath is justified in long cases.
Size by scope, not by habit
The inner passage must clear your customer's exact ureteroscope with margin. Send the fleet model when quoting; we verify before manufacturing — cheaper than discovering it in theatre.
