What Are Common Problems After Catheter Removal?

Urinary retention, painful urination, and urinary tract infections are the most frequent problems people face after a catheter is removed. The specific risks depend on the type of catheter, how long it was in place, and what surgery or condition made it necessary. Most post-removal issues resolve within days to weeks, but some can linger for months, especially after major procedures like prostate surgery where temporary incontinence is expected.

Urinary Retention Is the Most Immediate Concern

The single most common problem after removing a urinary catheter is acute urinary retention, which means you simply cannot urinate on your own even though your bladder is full. This happens because the bladder muscle, the detrusor, may have become sluggish from disuse during catheterization, or because surgical swelling around the urethra or prostate makes it physically harder to pass urine. Rates of urinary retention vary widely depending on the procedure. After colorectal surgery, roughly one in nine patients experienced retention in one study.¹ After laparoscopic stomach surgery, one study found rates above 20%, with the vast majority of those cases occurring when the catheter was pulled immediately after the operation.²

Retention usually means the catheter has to go back in, which is uncomfortable and frustrating. In post-prostatectomy patients specifically, the use of medications like tamsulosin (an alpha-blocker that relaxes smooth muscle in the bladder neck) has been shown to cut the rate of acute retention dramatically, from about 10% down to under 3%.³ If you are being discharged after surgery and have not urinated successfully yet, hospital teams typically perform a bladder scan to check how much urine is left behind. Some protocols set a threshold above which re-catheterization is considered necessary.⁴

Painful Urination, Burning, and Urgency

Even when urine flows normally, the first few voids after catheter removal often come with stinging, burning, or a feeling of urgency that seems out of proportion. This is sometimes called dysuria, and it is essentially the urethra’s response to having had a foreign object sitting in it. The lining of the urethra is delicate and can become irritated or mildly inflamed from the catheter’s presence. A trial comparing early versus delayed catheter removal after cesarean section found that the group who had their catheter taken out sooner experienced less urgency, dysuria, and burning on urination than those who kept the catheter longer.⁵ That pattern shows up across multiple types of surgery: the longer the catheter stays in, the more irritation you tend to feel when it comes out.

A large Cochrane review covering dozens of trials found moderate-quality evidence that shorter catheterization reduces both urinary tract infections and dysuria, even though it slightly increases the chance of needing re-catheterization for retention.⁶ In other words, there is a real trade-off: leave the catheter in longer and you lower the risk of retention but raise the risk of infection and discomfort. Most modern surgical protocols favor earlier removal because the infection and symptom benefits outweigh the small bump in retention risk.

Catheter-Associated Urinary Tract Infections

Urinary tract infections are the most well-known risk of catheterization, and the risk does not evaporate the moment the catheter comes out. Bacteria that colonized the catheter or the urethral lining during its stay can trigger a symptomatic infection in the days following removal. The Cochrane review mentioned above found that shorter catheter dwell time cut the rate of symptomatic catheter-associated infections roughly in half.⁶ Signs to watch for include cloudy or foul-smelling urine, fever, increased urgency, and pelvic or lower back pain. Mild bacteriuria, where bacteria are present in the urine but you feel fine, often clears without antibiotics after catheter removal. But if you develop fever or worsening symptoms, it generally warrants treatment.

Hospital teams have increasingly adopted nurse-driven protocols that prompt daily reassessment of whether a catheter is still needed, specifically to shorten dwell time and reduce infections.⁷ If you are a patient or a caregiver and a catheter has been in for more than a couple of days without a clear ongoing need, it is worth asking the care team whether it can come out.

Incontinence After Prostate Surgery

Temporary urinary incontinence is one of the most distressing problems after catheter removal, and it is especially common following radical prostatectomy. The prostate wraps around the urethra, so its removal can weaken the sphincter mechanism and affect pelvic floor support. In a large single-institution study of over 400 men after robot-assisted prostatectomy, only about 37% were continent within 48 hours of catheter removal. That climbed to roughly 54% at one week, 78% at four weeks, and 92% by twelve weeks.⁸ Most men regain continence within a few months, but that initial period of leakage can be significant and anxiety-producing.

Pelvic floor muscle training, essentially Kegel exercises, is one of the few interventions with good evidence for speeding recovery. A randomized controlled trial of men undergoing robot-assisted prostatectomy found that those who performed pelvic floor exercises three times daily had a statistically significant improvement in incontinence scores by three and six months compared to men who did not exercise.⁹ Another prospective study confirmed that pelvic floor rehabilitation was effective even in patients who started out with severe baseline incontinence, suggesting it is not just useful for mild cases.¹⁰ The exercises are also useful after transurethral resection of the prostate, where post-micturition dribbling and mild incontinence are common in the early weeks.¹¹

When the Timing of Removal Matters

One question that comes up constantly in hospital settings is whether the catheter should come out sooner or later. As already noted, shorter durations generally mean fewer infections and less irritation, while longer durations mean less retention risk. But there are subtleties.

In patients receiving epidural analgesia, for example, the situation is trickier. Epidurals blunt the nerve signals you need to sense a full bladder and coordinate voiding, so removing a catheter while an epidural is still running raises the retention risk. A meta-analysis of six studies found a higher rate of urinary retention when the catheter was pulled early in patients still on epidurals, though the infection rates between early and late removal did not differ significantly.¹² The practical takeaway is that if you have an epidural in place, your care team may leave the catheter in until the epidural is stopped or reduced.

Even the time of day seems to make a small difference. The same large Cochrane review found that removing a catheter late at night, around 10 PM to midnight, slightly reduced the risk of needing re-catheterization compared with early morning removal around 6 AM.⁶ The theory is that overnight removal gives the bladder time to gradually fill while you sleep, so by morning you have a natural urge to void. Though the evidence is rated as low certainty, many hospitals have adopted midnight removal as routine practice because the downside is essentially zero.

The Psychological Side of Catheter Removal

A frequently overlooked problem after catheter removal is anxiety. Having to urinate on your own after surgery, especially when you know retention is possible and re-catheterization might follow, creates genuine worry for many patients. A randomized trial comparing immediate versus slightly delayed catheter removal after stomach cancer surgery found that anxiety levels were markedly different between the two groups: about 27% of patients in the immediate-removal group reported increased anxiety on a validated scale, compared with nearly 60% of those in the early-but-still-catheterized group.¹³ In other words, having the catheter still in was more anxiety-inducing than having it out and dealing with the uncertainty. The catheter itself becomes a source of distress for many people, reminding them that something is “not right” with their body.

Post-prostatectomy incontinence can amplify this. Men who are leaking urine for weeks after surgery report embarrassment, social withdrawal, and reduced quality of life. It helps to know the typical trajectory ahead of time: for the vast majority of men, continence returns within six months. Setting realistic expectations before surgery appears to make the recovery period more manageable.

Problems After Vascular Catheter Removal

Urinary catheters get most of the attention, but central venous catheters, PICC lines, and hemodialysis catheters carry their own set of post-removal problems. These are fundamentally different risks because you are dealing with the bloodstream rather than the urinary tract.

The most feared complication is air embolism, which occurs when air enters the vein through the tract left behind by a central line. Though rare, it can be catastrophic. In one reported case, a patient suffered multi-organ damage, including injury to the kidneys, liver, and brain, from a paradoxical air embolism during central venous catheter removal. The patient also had an undiagnosed hole between the heart’s upper chambers that allowed the air to cross into the arterial system.¹⁴ Standard prevention involves having the patient lie flat, hold their breath during removal, and applying an occlusive dressing immediately afterward.

Deep vein thrombosis associated with a central line is another concern. When a clot has formed around the catheter, there is a theoretical worry that removing the catheter could dislodge it and send a piece to the lungs. However, research in patients with blood cancers found that early removal of a catheter associated with an upper-extremity clot did not increase the risk of pulmonary embolism compared with leaving the catheter in place or delaying removal.¹⁵ That said, patients who had their catheter removed without being started on blood thinners did have a small rate of progressive clotting events, reinforcing that anticoagulation matters more than leaving the catheter in.¹⁶

Rarer vascular complications include the formation of an abnormal connection between an artery and a vein at the catheter site, which can show up weeks or months after a hemodialysis catheter is removed. One case report described a patient who developed leg swelling six months after a femoral hemodialysis catheter was taken out, ultimately found to be caused by such an abnormal connection between the femoral vein and artery.¹⁷

Epidural Catheter Breakage

Epidural catheters, used for pain management during and after surgery, present a unique and unsettling complication: the catheter can break during removal, leaving a fragment inside the body. This is rare, but it is a known risk and one of the reasons removal is done carefully, pulling slowly and steadily with the patient in a position that straightens the spine. In one documented case, a long segment of catheter, about 8 cm, broke off during a difficult removal and had to be surgically extracted under general anesthesia.¹⁸ Retained fragments can be surprisingly hard to see on imaging, and in some cases, surgical intervention is necessary to retrieve them.¹⁹

Not every retained fragment requires surgery. If a fragment is small, located in soft tissue away from nerves, and causing no symptoms, some clinicians opt for observation with periodic imaging. The decision is made on a case-by-case basis, balancing the risks of surgery against the risks of leaving the fragment in place.

Suprapubic Catheter Tract Problems

Suprapubic catheters enter the bladder through the abdominal wall rather than the urethra, and they come with a distinct post-removal issue: the tract through the skin and abdominal wall can fail to close properly or can reopen. If the tract stays patent, urine can leak through it, forming what is called a fistula. One case report described a man whose previously healed suprapubic catheter site began leaking urine months after catheter removal, which turned out to be caused by a large bladder stone that had formed and was preventing normal drainage through the urethra.²⁰ The point is that persistent leakage from a suprapubic site is not always just a wound-healing issue; it can signal something else going on inside the bladder.

Post-Removal Complications in Children

Children are catheterized less frequently than adults, but when they are, they can experience a similar range of post-removal symptoms. A study of nearly 200 children who had diagnostic urinary catheterization in the emergency department found that about 21% reported at least one complication afterward. The most common were painful urination (10%), genital pain (8%), urinary retention (6%), and visible blood in the urine (5%).²¹ These numbers are worth knowing for parents, because a child who cries or refuses to urinate after catheterization is not necessarily experiencing a serious complication. Mild discomfort and apprehension are the norm rather than the exception.

In the pediatric setting, the catheter is typically in for a much shorter time than in adults, sometimes just minutes for a urine sample. Even so, one in five children had some degree of post-procedural complaint, which underscores how sensitive the urethral lining is, particularly in young children. Parents should be counseled to expect mild burning for a void or two and to seek medical attention if symptoms persist beyond a day or if fever develops.

When to Worry Versus When to Wait

The most practical question after catheter removal is distinguishing normal discomfort from something that needs attention. Some burning and urgency with the first few voids is essentially universal and not a reason to call the doctor. Mild pink-tinged urine for the first day or so is also common, especially after prostate procedures. These symptoms typically fade within 24 to 48 hours.

Situations that do warrant a call or a visit include:

No urination within 6-8 hours: If your bladder feels full and you cannot void at all, you may need re-catheterization. Do not wait all day hoping it will sort itself out.
Fever above 100.4°F (38°C): This could indicate a urinary tract infection or, after a central line removal, a bloodstream infection.
Heavy bleeding: Small amounts of blood are normal, but passing large clots or urine that looks like dark red or brown warrants evaluation.
Worsening pain over days: Post-removal discomfort should improve, not get worse. Escalating pain could indicate a stricture forming or an infection setting in.
Persistent leaking from a catheter site: After a suprapubic catheter removal, mild drainage for a day or two is expected. Ongoing leaking beyond that needs investigation.

Forcible removal of a catheter whose balloon has not been properly deflated can also cause urethral injury, which may lead to scarring and stricture formation down the line.²² If you have a catheter at home and are instructed to remove it yourself, always deflate the balloon completely before pulling. If the catheter does not slide out easily, stop and contact your provider rather than forcing it.
