length specification of all double-J ureteral stents (without pigtails)

IntroductionOn the following pages, we would like to provide you with a comprehensive portfolio of our ureteral stents. Regard-less of the indication, you are sure to find the appropriate product here.

materialPolyurethane (PUr)All UROTECH ureteral stents are pro-duced from aliphatic polyurethane (PUR) that has been specifically devel-oped for medical applications. Unlike other materials, PUR shows minimal adhesion to blood cells and has a very low-grade inflammatory effect on tissue due to its physical and chemi-cal properties. PUR becomes soft in a moist environment at body tempera-ture, significantly limiting the risks of

traumatic injury to surrounding tissue. Experimental tests and practical experi-ence have shown that PUR is one of the least thrombogenic and most tissue-compatible materials for implantable medical products.

Indwelling timeAll UROTECH ureteral stents are ap-proved for long-term use and can remain inside a patient for several months. The additional layer of phos-phorylcholine (PC) on the ureteral stents significantly reduces the risk of encrustation and infection.However, due to the heterogeneity of indications and individual differences between patients, regular follow-up examinations should be performed by the treating physician.

Length measurementsIn accordance with international norms (ASTMF-1828), the length of our ure-teral stents is always indicated without including the J-tip – this equals the shaft length (Fig. 1).

VariationsIn addition to our large catalog of standard ureteral stents, you can order many different custom variations based on your clinical needs.E.g. stents:66 with attached suture66 without drainage openings in shaft

Phosphorylcholine is a bio-compatible and durable seal-ing of the inner and outer

surface of implants to prevent biofi lm formation and subse-

quent encrustation. It is success-fully used not only in urology but also in other medi-cal fi elds (coronary stents, contact lenses). Since 10 years now UROTECH is successfully using Phosphoryl-choline coating (PC) on urological devices. Phospho-rylcholine verifi ably lowers the risk of encrustations andinfections, which results in prolonging the indwelling time of ureteral stents and nephrostomy catheters.

The PC coated surfaces show, independent from the material, signifi cant less adsorptions of bacteria. As a result Phosphorylcholine is highly suitable for urological applications.

… is comparable to the camoufl age protection of a chameleon. Chameleons change colour in response to changes in light, or temperature thus protecting itselves from enemies by adopting visually to its surroundings. PC coated ureteral stents use an intelligent thermal and bio-logical camoufl age effect sealing its surface against any environmental infl uences. For devices implanted in the urinary tract, encrustation of the implant`s surface is the most common technical problem.

Even a short time after implantation a biofi lm formation on the surface of catheters is observed, containing multi-ple microorganism and extracellular matrices. This biofi lm can be seen as a permanent reservoir of these bacteria, protecting them against antibiotic therapy and maintain-ing a catheter associated urinary tract infection (CAUTI). Most of these microorganism are forming ureasplitting enzymes (urease) resulting in an increasing ph-level of urine and in the biofi lm. If the ph-level exceeds the neu-tral point (ph=7), different soluted molecules precipitate and cristalize on the surface of the implant. An encrusta-tion is formed, the inner lumen of the catheter narrows and the implant doesn´t function anymore.

Phosphorylcholine coating keeps the pH level on the stent surface constant which minimizes the cristalization of molecules leading to a signifi cantly lower incrustation rate. Various clinical studies exist proving the effective-ness of Phosphorylcholine`s capacity of increasing the maximum indwelling time of ureteral stents.
