Double-J Ureteral Stent Set — 4 to 8 Fr, Standard & Hydrophilic
SKU: XY-DJS | Catéter Doble J — Set Ureteral 4 a 8 Fr, Estándar e Hidrofílico
The double-J is the consumable that defines a urology supplier: consumed in every lithotripsy, every ureteroscopy and every obstruction, and bought as an assortment because length is chosen per patient. Our set carries the stent with its two J-curls — proximal in the renal pelvis, distal in the bladder — plus the pusher and placement wire. Sizes 4 to 8 Fr (including the usual 4.8 and 6 intermediates) and lengths 20 to 28 cm, in open-open configuration allowing over-wire placement and exchange. The hydrophilic version cuts friction in difficult placements and stone disease; the standard covers the volume. Radiopaque markers and urine-stable material for the indicated dwell time. The closed-open tip configuration is made as OEM. The MOQ applies to the assortment total — which is how a real unit buys: a bell curve centred on 4.8–6 Fr × 24–26 cm.

A real unit's assortment
Length is chosen by patient height and anatomy; calibre by indication. No unit consumes a single combination — the correct order is the whole bell curve.
| Combination | Role in the assortment |
|---|---|
| 4.8–6 Fr × 24–26 cm | The centre of the bell — most of the volume |
| 4–4.8 Fr × 20–22 cm | Short patients and fine ureters |
| 6–7 Fr × 26–28 cm | Tall patients and stone-loaded dwells |
| 7–8 Fr | Large-calibre indications — smaller counts |
The MOQ applies to the assortment total, not to each combination. Hydrophilic and standard mix in the same order.
Frequently Asked Questions — Double-J Ureteral Stent Set — 4 to 8 Fr, Standard & Hydrophilic
Why is the double-J ordered as an assortment?
Because length is decided per patient — height and ureter anatomy — and calibre by indication. A real unit consumes a bell curve centred on 4.8–6 Fr × 24–26 cm with tails both ways. Ordering one combination guarantees running out of the right size mid-month. Our MOQ applies to the assortment total so the whole curve fits one order.
What does the open-open configuration add?
Both ends open allow over-wire placement start to finish and over-wire exchange without losing the track. It is the working standard. The closed-open tip — a closed point some units prefer for bladder comfort — is made as OEM with per-reference quantities.
Hydrophilic or standard?
Hydrophilic slides better in difficult placements, strictures and stone load; standard covers the volume at lower cost. The usual assortment is standard in volume with a hydrophilic fraction — both in the same order.
What documentation do you provide?
Technical file with the size chart, manufacturer ISO 13485 and per-batch sterilisation. The double-J is a dwelling device — classification is high in most markets and the distributor registers in destination.
