Urinary sheaths: choice, size and use

Key facts at a glance

• The urinary sheath is a collecting aid – it catches urine instead of absorbing it
• The German register of medical aids lists it under 15.25.04 “External urine collectors” in eight subgroups
• The most important difference: latex or latex-free – allergies come before the choice
• The clinical guideline recommends guided testing when putting it on, led by nursing professionals
• After the initial advice, a follow-up consultation should be offered – the first choice need not be the last

Many men only know pads and pants. Yet the urological guideline expressly names the urinary sheath (condom catheter) as a form of care in its own right. This article explains how it is classified, which variants there are and what matters when choosing.

Collecting instead of absorbing

The S2k guideline on advice on medical aids divides aids into three groups:

• absorbent – pads, pouches, protective pants, bed pads
• collecting – close to the body the urinary sheath, away from the body urine bottle, commode, raised toilet seat
• functional-anatomical – incontinence tampons

The difference is more than a classification. An absorbent product keeps urine close to the skin; a collecting one carries it away. For people whose skin reacts sensitively to moisture, this is the decisive point.

A urinary sheath is rolled over the penis and connected via a tube to a leg bag worn under clothing. At night, a larger night bag can be connected instead.

The guideline also names the urinary sheath where it matters most: in older people with multiple conditions and limited mobility. It distinguishes cleanly between independent continence and well-managed, socially acceptable incontinence – for many, the second is a realistic and entirely legitimate goal.

The eight variants in the register of medical aids

Under product group 15.25.04 “External urine collectors” are:

15.25.04.1	Urine collectors for women
15.25.04.2	Urine collectors for men
15.25.04.3	Urine collectors for children
15.25.04.4	Urinal sheaths/roll-on funnels, containing latex, not ready to use
15.25.04.5	Urinal sheaths/roll-on funnels, containing latex, ready to use
15.25.04.6	Urinal sheaths/roll-on funnels, latex-free, not ready to use
15.25.04.7	Urinal sheaths/roll-on funnels, latex-free, ready to use
15.25.04.8	Urinal sheaths/roll-on funnels for ISC, special form

Two distinctions run right through the list:

Latex or latex-free. Latex-free models are usually made of silicone. They are kinder to the skin, often transparent – which makes daily skin checks easier – and the only option for people with a latex allergy. The guideline expressly lists allergies among the details that must be known before a consultation.

Ready to use or not. Ready-to-use models already come with the skin adhesive. With non-ready-to-use ones, a skin adhesive is applied separately. Ready to use is much simpler in everyday life – especially when someone with limited hand function looks after themselves.

The special form 15.25.04.8 is intended for people who also catheterise intermittently.

What matters when putting it on

The exact steps are in the manufacturer's instructions for use and differ between systems. These points apply throughout, however:

• Size determines the hold. Every manufacturer includes a measuring guide. Too wide means leakage, too tight means pressure marks – estimated sizes almost always lead to one of the two problems.
• The skin must be clean and dry. Residues of creams, oils or lotions prevent the adhesive from holding.
• Hair interferes with the fit. It is trimmed, not shaved – shaved skin is irritated more quickly.
• The tube must not kink. A kinked tube backs up urine; this is the most common reason why a system appears to be “leaking”.
• Change once a day and look at the skin. Redness, pressure marks or swelling are a reason to change the system or the size.

The guideline goes further and makes practising a recommendation: practical testing with assistance, “for example putting on urinary sheaths”, can be offered – especially when difficulties have occurred or are to be expected with standard care. Nursing professionals take the lead here. So anyone who is unsure should not experiment alone but ask for it.

The first choice is not the last

Two recommendations of the guideline, both with strong consensus of 20 to 20 votes, are important here:

“After the initial consultation, a re-evaluation, if necessary an adjustment and follow-up consultation on the tested care should be offered and documented.”

And the result of this consultation should be communicated to the prescribing doctor – before a long-term prescription is issued. So if the first model does not fit, this is not a failure but the intended process.

When you should seek medical advice

The guideline lists warning signs for which medical assessment should take place before or alongside supply with medical aids – among others:

• red, cloudy or foul-smelling urine
• burning when urinating, pain in the lower abdomen
• back pain suggesting kidney involvement
• constant urination in small amounts
• skin changes
• newly occurring paralysis or sensory disturbances
• fever

Frequently asked questions

Who is a urinary sheath suitable for?

In principle for men with urinary incontinence whose anatomy allows a secure fit. Whether it fits in the individual case is clarified by the consultation – and best of all by a test.

Is there something similar for women?

The register of medical aids lists “urine collectors for women” under 15.25.04.1. These work differently from a urinary sheath and are far less common.

Can I get it on prescription?

Yes, external urine collectors are listed in the register of medical aids and can be prescribed. How the supply process works is explained in our article on medical aids on prescription.

Can I shower and sleep with it?

For the night, a larger night bag is usually connected. For showering, the system is generally changed – details are set out in the manufacturer's instructions for use.

Urinary sheath or pad?

This depends on skin condition, mobility, hand function and preferences. Both can be prescribed, and a switch is possible at any time. More on the absorbent alternatives in our article on pad, pants or brief.
