How to Avoid a Catheter: Strategies and Alternatives

Most indwelling urinary catheters placed in hospitals are medically justified at the time of insertion, but a substantial share stay in longer than necessary or go in when an alternative would have worked just as well. Every extra day with a catheter raises the chance of infection, discomfort, and reduced mobility, so the practical question for patients, families, and clinical teams is the same: what can replace the catheter, and when can it come out? The answer involves a mix of technology, protocol changes, alternative devices, medications, and patient involvement, each backed by a growing body of evidence.

Why Every Extra Day Matters

The core reason hospitals are rethinking catheter use is straightforward: each additional day an indwelling catheter stays in place raises the risk of both infectious and non-infectious complications. Catheter-associated urinary tract infections are among the most common hospital-acquired infections worldwide, and they are largely preventable. Beyond infection, catheters cause discomfort, limit a patient’s ability to get out of bed and walk, and can contribute to longer hospital stays.¹ When a bundled care approach was implemented across multiple ICUs at one medical center over five years, total catheter-associated infections dropped by more than 80%, and indwelling catheter use fell by about a third.² Those numbers illustrate what is possible when avoiding the catheter becomes a system-wide priority rather than an afterthought.

Bladder Scanning to Confirm Actual Need

One of the simplest ways to prevent an unnecessary catheter is to check whether the bladder actually needs draining before reaching for one. Portable bladder scanners use ultrasound to estimate urine volume in seconds, without any insertion. A systematic review found that using bladder ultrasound in patients suspected of acute urinary retention helps confirm or rule out the diagnosis, avoiding catheterizations that turn out to be unnecessary. Results were best when hospitals paired the scanner with a clear protocol spelling out the volume thresholds that justify catheterization.³

In postoperative patients, where temporary retention is common and often resolves on its own, a meta-analysis found that using bladder scanners to monitor residual urine volume reduced both unnecessary catheterizations and the urinary tract infections that come with them.⁴ An ICU study testing the accuracy of these devices found that dedicated bladder scanners correctly identified whether a patient needed catheterization in roughly 94 to 100 percent of cases when nurses used them, making them a reliable bedside tool.⁵ If you are a patient wondering whether the catheter is truly necessary, asking whether a bladder scan has been done is a reasonable starting point.

External Collection Devices

External devices sit outside the body and collect urine without anything entering the urethra or bladder. For men, the condom catheter has been available for decades: a sheath fits over the penis and drains into a bag. An expert clinical panel noted that multiple evidence-based guidelines recommend external collection devices as alternatives to indwelling catheters, though the panel also acknowledged a lack of rigorous comparative research on the topic.⁶ Condom catheters are not appropriate for every man. They require intact skin, adequate penile anatomy for the sheath to adhere, and they work best for managing incontinence rather than urinary retention, since they collect urine that the bladder is already releasing on its own.

For women, external options were historically limited, but newer “wicking” devices have changed that picture. These devices use a soft wick or adhesive collection system placed against the external anatomy. A systematic review and meta-analysis found that after hospitals introduced female external urine wicking devices, indwelling catheter use dropped by about 14 percent, and catheter-associated infection rates showed a trend downward as well.⁷ A large implementation study spanning over 220,000 patient days found that introducing a female external catheter significantly reduced indwelling catheter use in intensive care units.⁸ At one medical center, the introduction of female wicking devices was one of the interventions that had the clearest impact on infection rates across all ICUs.²

External devices are not a perfect substitute in all situations. They manage incontinence but do not drain a bladder that cannot empty itself. Patients with retention still need some form of catheterization. And like any device that sits against skin, external collectors can cause irritation or breakdown with prolonged use, so regular assessment is important.

Intermittent Catheterization Instead of Indwelling

When the bladder genuinely cannot empty on its own, intermittent catheterization offers a middle ground between leaving a catheter in around the clock and not catheterizing at all. A small, single-use catheter is inserted to drain the bladder and then immediately removed. This can be done several times a day and is a standard approach for many people with neurogenic bladder conditions at home.

One question patients and clinicians often have is whether intermittent catheterization actually lowers infection risk compared to an indwelling catheter. A study comparing the two methods in a large outpatient urology population found that the rate of diagnosed urinary tract infections was essentially the same: about 8 percent of patients using either method had a UTI at their visit, and roughly 44 to 46 percent had experienced at least one UTI in the past year.⁹ That finding is worth noting because it challenges the common assumption that intermittent catheterization is always dramatically safer from an infection standpoint. The advantage of intermittent catheterization lies more in the periods between catheterizations, when there is no foreign body in the bladder at all, along with greater mobility and comfort. For patients who have the dexterity and willingness to perform the technique (or a caregiver who can help), it often allows a more normal daily life.

Nurse-Driven Removal Protocols

One of the most effective system-level strategies is giving nurses the authority to remove catheters when standardized criteria are met, without waiting for a specific physician order. These nurse-driven protocols typically include a checklist: if the original indication for the catheter no longer applies and the patient does not meet any criteria for continued use, the nurse initiates removal.

The evidence here is strong. In a surgical trauma ICU, implementing a nurse-driven removal protocol cut the infection rate from about 5.1 to 2.0 infections per 1,000 catheter-days, a reduction of more than 60 percent.¹⁰ Another hospital saw its infection rate fall from about 1.0 to 0.27 per 1,000 catheter-days after introducing a similar protocol.¹¹ A randomized controlled trial testing automatic “stop orders,” which prompted daily reassessment and removal of catheters without clear indications, found that patients in the stop-order group had fewer total catheter days and fewer days of inappropriate catheter use.¹²

Making these protocols work in practice is not always straightforward. A qualitative study of hospitals across Michigan identified common barriers, including a lack of nursing engagement and the perception that toileting patients without a catheter adds to an already heavy workload. Successful sites addressed this by designating nurse champions who pushed the initiative at the unit level, using care aides to help patients get to the bathroom, and framing the protocol as something that benefits patients directly rather than merely reducing infection statistics.¹³ Another analysis of implementation barriers emphasized that building team skills and increasing awareness of why the protocols matter were both critical for success.¹⁴

Avoiding Catheters Around Surgery

Surgery is one of the most common reasons a catheter gets placed, but not every procedure requires one, and many that do require one do not require it for long. The Michigan Appropriate Perioperative criteria project used expert panels to rate catheter necessity across common general and orthopedic surgeries. Their findings sorted procedures into three groups: surgeries that can be done without a catheter at all, surgeries where a catheter is needed during the operation but should come out before the patient leaves the operating room, and surgeries where the catheter should stay in briefly but be removed for a first voiding trial as early as the day after surgery.¹⁵

Enhanced recovery after surgery programs have adopted similar guidance. For colon procedures, these programs recommend removing the catheter within 24 hours; for rectal procedures, within 72 hours.¹⁶ If you are scheduled for surgery and want to minimize catheter time, it is worth asking your surgeon ahead of time whether the procedure falls into the “no catheter needed” or “intraoperative only” category, and what the plan is for removal if one does go in.

Behavioral Approaches for Managing Incontinence

Some patients receive catheters not because their bladder cannot empty, but because managing incontinence seems simpler when a catheter does the work. In those cases, toileting programs offer a non-invasive alternative. Prompted voiding, where a caregiver checks in on a regular schedule, asks whether the patient needs to use the bathroom, and assists with toileting, has been shown to reduce the frequency and severity of incontinence episodes, particularly in older adults with cognitive impairment.¹⁷

Timed voiding is a related strategy where patients are taken to the bathroom on a fixed schedule rather than waiting for them to feel the urge. In a Cochrane review, one trial combining timed voiding with staff education and continence products found that only about 20 percent of participants in the intervention group were incontinent when checked, compared with 80 percent receiving usual care.¹⁸ These approaches require more staff effort than inserting a catheter, which is a genuine barrier in understaffed facilities. But for patients who can participate, they avoid the risks of catheterization entirely.

Medications That May Help

In some cases, drugs can address the underlying problem that would otherwise lead to catheterization. Tamsulosin, an alpha-blocker widely used in men with enlarged prostates, relaxes smooth muscle in the bladder neck and prostate, making it easier to urinate. More recently, researchers have looked at tamsulosin for urinary retention in older women, an off-label use. A review concluded that tamsulosin may be a safe alternative to catheterization for managing urinary retention in older women, potentially reducing catheter-associated complications.¹⁹ Medication is not a universal fix. It works best when retention is mild to moderate and related to smooth muscle tone rather than a complete mechanical obstruction. But it can be the difference between going home with or without a catheter for some patients.

Suprapubic Catheters as an Alternative Route

When long-term catheterization is unavoidable, the tube does not have to go through the urethra. A suprapubic catheter enters the bladder through a small incision in the lower abdomen. This route avoids the urethral trauma and discomfort associated with standard catheters, which matters for patients who will be catheterized for weeks or months.

A Cochrane systematic review comparing the two routes found that patients with urethral catheters had roughly twice the rate of asymptomatic bacteriuria and reported substantially more pain than those with suprapubic catheters.²⁰ In nursing home residents needing catheters for 90 days or more, those with suprapubic catheters had a lower rate of catheter-associated UTIs, were about half as likely to be hospitalized, and used fewer antibiotics. The tradeoff: suprapubic catheter users were more likely to be colonized with multidrug-resistant organisms, a concern for infection control in long-term care settings.²¹

After prostate surgery, a setting where catheterization is standard for healing, one study found that patients who received a suprapubic catheter returned to continence faster than those with a urethral catheter (a median of 7 days versus 16 days) and were more likely to be continent at the time of catheter removal.²² A suprapubic catheter still requires a minor procedure to place it, so it is not a casual swap. But for patients facing weeks of catheterization, the comfort and outcome advantages are worth discussing with the surgical team.

When Avoiding Catheters Goes Too Far

There is a real tension in this space. Hospitals are strongly incentivized to reduce catheter use because regulators penalize high infection rates, and the push has achieved genuine gains for patients. But pulling catheters too aggressively or refusing to place them when needed creates its own problems. One surgical center reported that after changing its policy to reduce catheter use, the incidence of urinary retention and its associated complications actually increased.²³ Urinary retention, left unmanaged, can damage the bladder and kidneys. The goal is not to eliminate catheters entirely but to use them only when needed and remove them as soon as they are no longer necessary.

Electronic medical record alerts, which pop up to remind clinicians to reassess catheter necessity, have shown mixed results. One large hospital system found that after implementing a best-practice alert in their electronic records, infection rates in non-ICU patients dropped, but infection rates in the adult ICU actually rose, from 0.2 to 1.8 per 1,000 catheter-days, even though catheter use in that group had decreased.²⁴ The reasons are not entirely clear, but one possible explanation is that alerts alone, without the nursing engagement and behavioral changes that make protocols work, can produce uneven results. A pop-up reminder is not the same as a nurse champion.

What You Can Do as a Patient

Patients often do not realize they have leverage in this conversation. A study surveying hospitalized patients found that a substantial portion did not know why their catheter was in place, and although the catheter caused symptoms, most patients never asked whether it could be removed.²⁵ The researchers concluded that doctors should be giving more information and asking more questions about catheters, and that quality improvement initiatives should encourage patients to participate actively.

Research into the behavioral side of catheter removal found that patients themselves identified several barriers to speaking up: feeling dependent on the catheter, worrying about not having bathroom access or staff help with toileting, and picking up on ward culture cues that discouraged questions. On the enabling side, patients were more likely to push for removal when they saw it as a step toward going home, and when family members supported them in the conversation.²⁶

Practical questions worth asking your care team include: Is this catheter still needed today? Has a bladder scan been done to check whether I am retaining urine? Would an external device work instead? What is the plan and timeline for removal? These are not confrontational questions. They are the same questions the best catheter-reduction protocols prompt clinicians to ask themselves daily. You are just making sure the question does not get skipped on a busy shift.

The Economics Behind the Push

Hospitals are not just motivated by clinical outcomes. Catheter-associated infections carry financial consequences: extended stays, additional treatments, regulatory penalties, and unreimbursed costs. A systematic review of quality improvement programs aimed at reducing these infections found that, across a dozen studies, interventions were associated with an average 43 percent reduction in infections. The net cost of running these programs varied widely, from saving money to adding costs depending on the hospital’s starting point and approach.²⁷ For patients, this economic pressure is mostly a good thing: it means hospitals have strong incentives to pursue the strategies described above. The caution, as noted earlier, is that financial incentives to avoid catheters can occasionally tip the balance too far in settings where retention monitoring is not equally rigorous.
