Safe Solutions for Continuous Transurethral Urinary Drainage

Are you seeking a modern safe solution for continuous bladder catheterisation?

The patient’s health and well-being is our motivation to make transurethral urinary drainage, especially when used long-term, as safe as possible. We offer a variety of products which effectively reduce the following sources of irritation of the urethra which can lead to urinary tract infection:

  • mechanical, e.g. by encrustations on the catheter itself
  • bacterial
  • intolerance of the material

Our entire indwelling bladder catheters are all:

Gentle – the urethra and the sensitive urethral mucosa are preserved

Safe – sterile and extremely gentle application minimises risk of urinary tract infections

Smooth – little tendency to form encrustation and biofilm

Flexible – elastic but firm material for easy insertion and maximum wearing comfort

Tolerable – high biocompatibility

Efficient – fast and continuous drainage performance

The minimum requirements to produce a quality foley catheter are:

  • tolerable
  • smoothly rounded catheter tips and drainage openings (eyes)
  • safe anchoring of the balloon and smooth transition between balloon and shaft
  • valve for secure connection to a Luer or Luer-lock syringe tip
  • colour-code on the catheter for safe identification of the size
  • sterile individual packaging

We strive to find optimal solutions to make continuous transurethral urinary drainage as safe, as easy and as time-saving as can be, extremely comfortable and of course also economical.

Based on advanced technology and high quality standards we offer a full range of products for indwelling catheterisation focused on the needs of our patients without neglecting the requirements of doctors and nursing staff.

The product information gives an overview of our indwelling catheter systems.

If you have any questions or need help or advise, please contact us.

How does the permanent transurethral urinary drainage system work?

The indwelling catheter, which can stay in the urethra and bladder for several days or weeks depending on the material and the personal situation of the user, drains the urine via a soft tube, usually made of silicone or latex, and collects it in a urine collection bag.

The catheter is inserted through the urethra into the bladder. The balloon is then inflated by sterile water or, in case of a silicone balloon, preferably by a 10% glycerine solution as it does not diffuse through the silicone wall of the balloon to any important extent. Once the balloon is inflated, the catheter is prevented from coming out of the bladder and so stays in place.

What is important to consider for permanent transurethral urinary drainage?

One of the most important considerations in long-term use of an indwelling bladder catheter is that the material itself should have a low tendency to form encrustations and biofilm, is optimally tolerated by the body, and therefore does not cause any irritations of the urethral mucosa. Furthermore, the catheter should be flexible and supple to ensure the greatest possible wearing comfort.

What alternatives are there?

In order to avoid the risk of urinary tract infections, indwelling bladder catheters should not be applied unless a doctor has determined by strict criteria that this is indicated, and should be removed again as soon as possible. 

If patients prefer to handle and control urine drainage by themselves, the intermittent self-catheterisation products are an option providing that the medical requirements are met.

Patients who need a medium or long-term urine drainage, e.g. due to occlusion of the urethra, narrowing of the urethra or enlargement of the prostate, especially if their manual capabilities are limited, may find the suprapubic urine drainage products an option.

THE MODERN INDWELLING CATHETER – important criteria

Which features are necessary to meet the demands of a modern and safe indwelling catheter?

A high quality, safe and modern indwelling catheter needs a combination of

  • the right smooth material which
    - has a low tendency for formation of encrustations and biofilm
    - is easily tolerated by the body
    - is gentle to the urethral mucosa
    - is non-allergic
    - is flexible and supple to ensure the highest level of wearing comfort
  • adequate and softly rounded catheter tip
  • large enough softly rounded catheter eyes
  • non-diffusible inflation liquid for the balloon

You will find that all these important criteria for long-term use of an indwelling bladder catheter are part of the Teleflex indwelling catheter programme.

We offer a broad range of indwelling catheters in different sizes and with different types of tips.

Please find more information about our material, catheter tips and inflation liquid on the next flags.

CATHETER TIPS

All Teleflex indwelling catheters are available with two different tips:

Cylindrical tip:
The straight cylindrical tip is easy to use in the anatomically normal urethra. This finely rounded cylindrical tip ensures that the catheter can be advanced gently and atraumatically through the urethra.

Tiemann tip:
The curved and slightly tapered Tiemann tip ensures highest control during catheterisation and allows narrow passages in the male urethra to be passed safely and reliably.

SILICONE – highly biocompatible.

Silicone is the ideal catheter material for long-term application, up to 12 weeks. Most of our indwelling balloon catheters are made of pure silicone. They are characterised by their smooth surface both on the inside and on the outside. The risk of encrustations and formation of a biofilm is therefore very low.

Silicone is a highly biocompatible material. Irritations of the skin or the urethra or allergic reactions very seldom occur. 

Our silicone catheters are colorant-free, and therefore transparent, to facilitate monitoring whether a catheter needs to be changed.

The catheter can be inserted easily and safely due to the firm, yet flexible, quality of the material. This offers a high level of wearing comfort. 

LATEX* – highly flexible.

Latex is one of the most commonly used catheter materials. Due to its high flexibility, latex material offers high wearing comfort.

Teleflex offers two types of coated catheters made of natural latex compound:

  • SympaCath AquaFlate – These catheters are made of hydrogel coated latex and can be used for long-term application up to 12 weeks.
  • PTFE AquaFlate – These catheters are made of PTFE coated latex which is suitable for short- and medium-term care up to 28 days.

* Catheters containing natural latex can provoke an allergic reaction and must not be used for sensitised patients. We recommend that sensitised patients use only pure silicone balloon catheters.

It is recommended to use silicone indwelling catheters for children, since latex can lead to irritations of the urethral mucosa, which can increase the risk of urethral strictures formation. Exclusive use of silicone catheters ensures that children do not become sensitised to latex and so develop a latex allergy.

GLYCERINE SOLUTION – for inflation of silicone balloons

Teleflex recommends using 10% glycerine solution for inflating silicone balloons.

Glycerine solution does not diffuse through the silicone wall of the balloon to any important extent (fig. 1). In silicone balloon catheters inflated with glycerine solution, the reduction in fill volume of the balloon after an indwelling time of 6 weeks is negligible. 

In contrast, silicone balloons filled with sterile water diffuse clearly and suffer a reduction of over 50% (fig. 2). 

Therefore the 10% glycerine solution means:

  • no more regular checks and repeated filling of the balloon, which gives the patient more rest and is cost and time saving 
  • the balloon anchors safely without risk of catheter dislocation
  • reduction of irritation: due to the constant firmness of the balloon there are no wrinkles and the surface is smooth – the potential for formation of deposits is low
