Catheters & Bed Pads: Choosing the Right Supplies
A clinician-directed buyer's reference for intermittent, indwelling, and external catheters — plus the underpads, drainage bags, and securement that keep home continence care clean and low-risk.
Daily Living · Continence CareThree Catheter Families, Three Different Reasons
Catheter choice is a clinical decision first and a supply decision second — your prescriber or continence nurse sets the type and French size before you stock anything. The three families exist for genuinely different situations, and they aren't interchangeable.
Intermittent catheters are inserted to drain the bladder and then removed, used a set number of times per day. They carry the lowest infection risk of the three because nothing stays indwelling, which is why they're the preferred long-term route when self-catheterization is feasible. Indwelling (Foley) catheters stay in place, held by a small inflated balloon, and drain continuously into a bag — the right answer for retention, post-surgical drainage, or when intermittent isn't practical, but every indwelling day adds CAUTI risk. External (condom/Texas) catheters sit outside the body and route urine to a bag; for male anatomy with reliable bladder emptying, they sidestep insertion entirely.
The honest catch worth naming: more continuous drainage means more infection exposure. Indwelling is the most convenient and the highest-risk; that trade-off is exactly why it's prescribed, not chosen off a shelf.
How to Match Supplies to the Prescription
Once the type and French size are set, these are the specification decisions that change comfort, cost, and infection risk in real homes.
1 · Confirm the French size (Fr)
French sizing measures the outer diameter — each French is 1/3 of a millimeter, so a 14 Fr is larger than a 12 Fr. Bigger drains faster but is harder on tissue; your clinician specifies it. Order the size on the prescription, not a guess, and keep one box of the exact size on hand rather than mixing.
2 · Decide coated vs. uncoated
Uncoated catheters need a separate water-based lubricant and cost the least. Coated options — hydrophilic catheters that activate with water, or pre-lubricated closed systems — reduce friction and urethral trauma. For frequent daily intermittent use, the coated premium often pays for itself in comfort and fewer micro-injuries; for occasional use, uncoated is a reasonable, cheaper call.
3 · Weigh closed-system vs. straight
A closed (touchless) system keeps the catheter sealed in a collection bag with an introducer tip, so fingers never touch the insertion length — the lowest-contamination intermittent option, favored for anyone prone to UTIs or catheterizing away from a clean home setting. Straight catheters are simpler and far less expensive for low-risk users with good hand hygiene.
4 · Right-size the underpads (chux)
Disposable underpads are convenient and predictable; reusable, washable pads cost more upfront but win on long-term spend and landfill if your laundry can keep up. Match absorbency to overnight vs. daytime use — a heavier overnight pad and a lighter daytime one beats one mismatched pad doing both jobs.
5 · Stock drainage and securement
Indwelling users need both a large overnight drainage bag and a discreet leg bag for daytime, plus securement (a leg strap or adhesive anchor) that stops the tubing from tugging at the insertion site. Securement is the quietly important piece — traction at the urethra is a real source of both pain and infection.
Frequently asked questions
What does the French (Fr) number actually mean?
It's the catheter's outer diameter — one French equals one-third of a millimeter, so a 16 Fr is wider than a 12 Fr. Larger sizes drain faster but are harder on delicate tissue. The number is a clinical specification: order the exact Fr your prescriber listed rather than sizing up or down on your own.
Is a hydrophilic or closed system worth the extra cost?
It depends on how often you catheterize and your infection history. Hydrophilic-coated and closed systems reduce friction and contamination, which matters most for multiple daily insertions or anyone with recurrent UTIs. For an occasional, low-risk user with solid hand hygiene, a straight uncoated catheter with separate lubricant is a perfectly sound — and much cheaper — choice. We'd rather name that than upsell the premium kit to everyone.
How do I lower infection risk with an indwelling catheter?
Hand hygiene before and after handling, keeping the drainage bag below bladder level so urine never flows backward, securing the tubing to prevent tugging at the insertion site, and not disconnecting the closed system unnecessarily. The single biggest lever is fewer indwelling days overall — every catheter-free day removes a route for infection, which is why clinicians push to discontinue as soon as it's safe.
Reusable or disposable underpads — which should I stock?
Disposable chux are simpler and predictable, ideal for travel, guests, or anyone without easy laundry. Reusable washable pads cost more per unit but win decisively on long-term spend and waste if you can run them through a hot wash regularly. Many homes keep both: reusables for the everyday bed, a sleeve of disposables for trips and backup.
Can I switch catheter types myself if one isn't working?
No — type and size are clinical decisions tied to your bladder function, anatomy, and risk profile. If a catheter is uncomfortable, leaking, or causing repeated infections, that's a conversation to have with your prescriber or continence nurse, who may adjust the size, switch families, or change the coating. We can help you source whatever they specify once it's set.
