Urinary Incontinence After Prostate Cancer Treatment: Causes, Recovery and Treatment

Why urinary leakage occurs after prostate surgery or radiotherapy, how long recovery may take, and what can be done when symptoms persist

By Mr Neil Haldar, Consultant Urological Surgeon

Urinary incontinence is one of the concerns men raise most frequently when considering treatment for prostate cancer.

For some, the possibility of losing urinary control is almost as worrying as the cancer itself. Men may be concerned about wearing pads, returning to work, exercising, travelling, sleeping normally or maintaining confidence in social and intimate situations.

These concerns are entirely understandable. However, urinary incontinence after prostate cancer treatment is often misunderstood.

Following radical prostatectomy, some degree of leakage is common in the early stages of recovery, but urinary control usually improves substantially over time. Radiotherapy is less likely to cause immediate stress incontinence but can produce urgency, frequency and other bladder symptoms, sometimes months or years after treatment. For the smaller number of men who develop persistent or severe leakage, effective treatments are available.

Understanding why urinary problems occur, what recovery normally looks like and when further investigation is appropriate can make the treatment journey much less daunting.

In brief

• Early prostate cancer usually causes no urinary symptoms.
• Urinary leakage is more commonly a consequence of prostate cancer treatment than of the cancer itself.
• Leakage is common immediately after radical prostatectomy but usually improves considerably during the first year.
• Radiotherapy more commonly causes urgency, frequency and urge leakage than classic stress incontinence.
• Pelvic-floor muscle exercises are routinely recommended, although there is no single programme proven to be best for every man.
• Severe leakage, leakage that is not improving or symptoms that substantially affect quality of life should be assessed rather than simply endured.
• Persistent stress incontinence can often be treated successfully with a male sling or artificial urinary sphincter.

How are the prostate and urinary control connected?

The prostate is a gland situated immediately beneath the bladder. It surrounds the first part of the urethra, the tube through which urine leaves the bladder and passes out of the body.

Because the prostate sits at the junction between the bladder and urethra, treatment in this area can affect several structures involved in urinary control.

Male continence depends on a coordinated system rather than a single muscle.

The bladder stores urine at low pressure. The bladder neck and proximal urinary sphincter help keep the outlet closed during filling. Below the prostate, the external urinary sphincter provides much of the voluntary control that allows a man to delay passing urine. The pelvic-floor muscles provide additional support, while the surrounding nerves coordinate storage and emptying.

During radical prostatectomy, the prostate is removed, and the bladder is reconnected to the urethra. This necessarily changes the bladder-neck or proximal continence mechanism. Urinary control after surgery therefore depends more heavily on the external sphincter, the remaining length of healthy urethra, the pelvic floor and the supporting tissues around them.

This is why precise preservation of the continence mechanism is such an important part of prostate surgery.

Can prostate cancer itself cause urinary problems?

Early prostate cancer usually causes no urinary symptoms. It may develop in the outer part of the gland without significantly narrowing the urethra or interfering with bladder emptying.

When urinary symptoms occur, they may include:

• a weaker urinary stream;
• difficulty starting to urinate;
• stopping and starting during urination;
• a feeling that the bladder has not emptied completely;
• increased urinary frequency;
• urgency;
• getting up repeatedly at night to pass urine;
• occasionally, an inability to pass urine.

However, these symptoms are much more commonly caused by benign prostatic enlargement than by prostate cancer. Benign enlargement becomes increasingly common with age and can produce symptoms almost identical to those caused by obstruction from prostate cancer.

The presence of urinary symptoms does not therefore mean that a man has prostate cancer. Equally, the absence of urinary symptoms does not exclude it. Symptoms, PSA results, examination findings, family history, ethnicity, age and, where necessary, MRI findings all need to be considered together.

Which prostate cancer treatments can affect urinary control?

Different treatments affect urinary function in different ways. This is one reason men should have the opportunity to discuss treatment choices and their potential side effects with both a specialist surgeon and a clinical oncologist before deciding how to proceed. NICE recognises active surveillance, radical prostatectomy and radical radiotherapy as appropriate options for different groups of men with localised prostate cancer, depending on the cancer and the individual circumstances.

Radical prostatectomy

Radical prostatectomy involves removing the entire prostate gland and seminal vesicles, followed by joining the bladder to the urethra.

It is one of the established treatments intended to cure localised or locally advanced prostate cancer in appropriately selected men. Whether it is the right treatment depends on factors including the cancer’s grade, stage and location, the man’s general health and life expectancy, and his priorities regarding urinary and sexual function.

When the urinary catheter is removed after surgery, many men initially experience stress urinary incontinence. This means that urine leaks when pressure inside the abdomen rises, for example when:

• standing up;
• coughing or sneezing;
• laughing;
• bending;
• lifting;
• walking quickly;
• exercising.

Leakage may be particularly noticeable later in the day, when the pelvic-floor muscles are tired, or when the bladder is relatively full.

For most men, control improves progressively as postoperative swelling settles, the sphincter recovers, and the pelvic floor adapts to its increased role.

Does robotic surgery reduce the risk?

Robot-assisted radical prostatectomy provides the surgeon with magnified three-dimensional vision and allows very precise movements within the pelvis.

However, the use of a robot does not by itself guarantee an excellent continence result.

Recovery depends on several interacting factors, including:

• the man’s preoperative urinary function;
• his age, weight and general fitness;
• the anatomy of the sphincter and urethra;
• the size of the prostate;
• the extent and location of the cancer;
• whether the bladder neck, urethral length, nerves and supporting structures can be preserved safely;
• the surgeon’s judgement, experience and technique.

Nerve-sparing surgery may help functional recovery when it is oncologically safe, but preserving the nerves must never take priority over adequately treating the cancer.

A careful operation aims to achieve the best possible balance between cancer control and preservation of the structures responsible for urinary and sexual function.

Radiotherapy

External-beam radiotherapy and brachytherapy usually cause less immediate stress incontinence than radical prostatectomy.

Radiotherapy can, however, irritate the bladder and urethra. During treatment or shortly afterwards, men may experience:

• urinary frequency;
• urgency;
• waking repeatedly at night;
• discomfort when passing urine;
• a weaker stream;
• urge incontinence.

Urge incontinence occurs when a sudden, compelling need to urinate is followed by leakage before the man can reach a toilet.

For many men, these irritative symptoms improve after treatment. In a minority, urinary problems can appear or worsen months or years later because radiotherapy can produce gradual changes in the bladder, urethra and surrounding tissues.

Radiotherapy can also influence the treatment options available if significant stress incontinence subsequently develops. Previous pelvic radiotherapy may make tissues less resilient and can reduce the likelihood of success from some male sling procedures. It may also increase the complexity and long-term risks of artificial urinary sphincter surgery.

Focal and ablative treatments

Focal treatments such as high-intensity focused ultrasound aim to treat only the area of clinically significant cancer while preserving as much of the remaining prostate and surrounding tissue as possible.

Because the entire prostate and continence mechanism are not removed, the risk of significant urinary incontinence is generally lower than after radical prostatectomy.

These treatments are not suitable for every cancer. Careful selection and appropriate follow-up are essential because untreated prostate tissue remains in place.

Hormone therapy

Androgen-deprivation therapy does not normally cause urinary incontinence directly.

It can have other important side effects, including hot flushes, fatigue, loss of muscle mass, weight gain, sexual dysfunction and changes in bone and metabolic health. If hormone treatment shrinks a large prostate or prostate cancer, it may sometimes improve obstruction-related urinary symptoms.

Transurethral procedures

Some men with advanced prostate cancer require an operation through the urethra to relieve obstruction and improve bladder emptying.

These procedures may be helpful when a tumour or enlarged prostate is restricting urine flow. Because they involve tissue close to the bladder neck and sphincter, they can occasionally affect continence.

What are the different types of urinary incontinence?

Not all urinary leakage is caused by the same problem. Identifying the type of incontinence is essential because the appropriate treatment differs.

Stress urinary incontinence

Stress incontinence is leakage during physical movement or effort.

It is the most characteristic form of leakage after radical prostatectomy and reflects reduced resistance at the urinary sphincter.

A man may leak when coughing, lifting, rising from a chair, walking, playing sport or performing strenuous activity. Some men remain dry while sitting or sleeping but leak whenever they are active.

Urge incontinence

Urge incontinence is leakage associated with a sudden, difficult-to-control need to pass urine.

It is usually related to overactivity or irritation of the bladder rather than weakness of the urinary sphincter. It can occur before treatment, after radiotherapy or alongside stress incontinence following surgery.

Mixed incontinence

Mixed incontinence means that both stress and urgency-related leakage are present.

For example, a man may leak when coughing but also experience sudden urgency and occasional leakage on the way to the toilet.

It is important to identify both components because treating only the sphincter weakness may not resolve the urgency.

Overflow incontinence

Overflow leakage occurs when the bladder does not empty properly and becomes overly full.

Possible causes include:

• narrowing at the bladder neck;
• a urethral stricture;
• persistent prostate obstruction;
• poor contraction of the bladder muscle;
• certain medications;
• neurological conditions.

Men may notice a weak stream, difficulty starting, prolonged urination, incomplete emptying or continuous dribbling.

Continuous leakage

Persistent leakage that occurs regardless of movement or bladder sensation is uncommon.

It may indicate severe sphincter weakness or another specific problem and should be investigated rather than assumed to be a normal part of recovery.

How long does incontinence last after radical prostatectomy?

Recovery varies considerably between individuals.

Immediately after the catheter is removed, some men have relatively good control, while others require several pads each day. Early leakage does not necessarily predict the final result.

The greatest improvement often occurs during the first three to six months. Further recovery can continue throughout the first year and, in some men, beyond it.

It is important to understand that published continence figures are difficult to compare. Different studies define continence in different ways. Some count only men who use no pads at all. Others include men who wear one small security pad despite having little or no meaningful leakage.

When discussing expected outcomes, it is therefore more helpful to consider:

• whether the man is completely pad-free;
• how many pads he uses;
• how wet those pads become;
• whether leakage occurs only during strenuous activity;
• how much the problem affects everyday life.

The overall direction of recovery matters. A man reducing from several heavily wet pads to one lightly damp pad is making meaningful progress even though he is not yet completely continent.

What influences the return of urinary control?

Continence recovery is affected by both patient-related and treatment-related factors.

These may include:

• age;
• baseline bladder and urinary function;
• weight and physical fitness;
• diabetes or neurological disease;
• prostate size;
• previous prostate procedures such as TURP or HoLEP;
• the length and function of the external urinary sphincter;
• the amount of healthy urethra that can be preserved;
• the extent and position of the cancer;
• whether nerve and supporting-tissue preservation is oncologically safe;
• surgical experience and technique;
• previous or subsequent radiotherapy;
• postoperative scarring or narrowing.

A younger, physically fit man with good preoperative urinary control may recover more quickly, but age alone does not determine the outcome. Older men can also regain excellent continence.

Equally, even technically successful surgery may be followed by slower recovery because of individual anatomy, bladder behaviour or healing.

What can men do to help continence recovery?

Pelvic-floor muscle exercises

Pelvic-floor muscle exercises are routinely recommended following radical prostatectomy.

These muscles support the bladder and urethra and contribute to voluntary urinary control. Learning how to contract them correctly can help a man use the remaining continence mechanism more effectively.

Many centres teach the exercises before surgery so that the man becomes familiar with the correct muscles before his catheter is inserted. Exercises are then resumed after catheter removal according to the advice of the treating team.

The evidence does not identify one ideal pelvic-floor programme for every man, and research into formal training, biofeedback and combinations of treatments remains mixed. Nevertheless, specialist instruction can be valuable, particularly when a man is unsure whether he is contracting the correct muscles or when recovery is slower than anticipated.

Common mistakes include:

• tightening the buttocks rather than the pelvic floor;
• holding the breath;
• strongly contracting the abdominal muscles;
• practising only while passing urine;
• performing excessive numbers of contractions without allowing the muscles to recover.

Pelvic-floor exercises should be performed correctly and consistently rather than forcefully or continuously.

A specialist pelvic-health physiotherapist can assess technique, muscle strength, endurance and coordination and provide an individual programme.

Sensible fluid intake

Reducing fluids excessively is rarely helpful.

Concentrated urine can irritate the bladder, worsen urgency and increase the risk of infection. Conversely, drinking very large volumes can increase frequency and leakage.

Most men benefit from spreading an appropriate amount of fluid through the day and reducing excessive drinking in the evening if night-time urination is troublesome.

Caffeine and alcohol

Caffeine and alcohol can increase urinary urgency and frequency in some men.

Coffee, tea, energy drinks, cola and certain fizzy drinks may aggravate bladder symptoms. There is no need for every man to avoid them completely, but reducing intake may help when urgency is prominent.

Bladder training

Men with urgency may begin visiting the toilet very frequently “just in case”.

Over time, this can reduce confidence in the bladder’s ability to store urine and reinforce a pattern of frequent urination.

Bladder training involves gradually extending the interval between toilet visits while using techniques to control urgency. It is more appropriate for urgency-related symptoms than for severe stress leakage.

Maintaining a healthy weight

Excess abdominal weight increases pressure on the bladder and pelvic floor and can make stress leakage more noticeable.

Regular physical activity and maintaining a healthy weight can support recovery, although high-impact exercise may initially need to be reintroduced gradually.

Avoiding constipation

Straining during bowel movements increases pressure on the pelvic floor.

Adequate fluid, fibre and activity can help maintain regular bowel function. Men taking painkillers after surgery should be aware that some medications can cause constipation.

Stopping smoking

Stopping smoking benefits cardiovascular, respiratory and cancer-related health.

It may also reduce chronic coughing, which repeatedly increases pressure on the urinary sphincter and can worsen stress leakage.

Can medication help?

Medication does not usually correct the sphincter weakness responsible for stress incontinence after prostatectomy.

It can, however, help when urgency, frequency or an overactive bladder contributes to the problem.

Depending on the individual circumstances, treatment may include medication that reduces involuntary bladder contractions or relaxes the bladder during filling.

Before prescribing medication, the clinician may need to confirm that the bladder is emptying adequately. Some bladder-relaxing drugs can worsen retention in men who already have poor emptying.

Medication is often used alongside bladder training, fluid adjustment and pelvic-floor work rather than as a standalone treatment.

Pads, sheaths and other practical aids

Containment products do not cure incontinence, but they can make an enormous difference to confidence and quality of life while recovery continues.

Modern male continence pads are discreet and designed to fit the male anatomy. The correct size and absorbency should be used; a larger pad is not always more comfortable or effective.

Other options include:

• absorbent pull-up garments;
• external urinary sheaths connected to a drainage bag;
• bed or chair protection;
• selected compression devices used under specialist guidance.

Skin should be kept clean and dry, and barrier products may help men who experience irritation.

Using a pad should not be regarded as a failure. It is a practical way of allowing a man to remain active, work, travel and exercise during recovery.

What happens if continence is not improving?

Men should not feel that they must simply tolerate persistent incontinence.

Continence often continues to improve during the first year, but the pattern and severity of leakage should be reviewed if:

• there is little or no improvement;
• several heavily wet pads are still needed;
• leakage is continuous;
• urinary flow is weak;
• the bladder does not seem to empty;
• urgency or night-time urination is prominent;
• infections are recurring;
• symptoms are significantly affecting daily life.

NICE recommends that men with troublesome urinary symptoms after prostate cancer treatment have access to specialist continence services for assessment, diagnosis and conservative management.

An assessment may include:

• a detailed history of when and how leakage occurs;
• a bladder diary;
• the number, type and wetness of pads used;
• examination of the abdomen, genitalia and pelvic floor;
• urine testing;
• measuring urinary flow;
• checking how much urine remains after voiding;
• a pad-weight test;
• flexible cystoscopy;
• urodynamic testing in selected cases.

The purpose is to determine whether the main problem is sphincter weakness, bladder overactivity, poor bladder emptying, narrowing of the urethra or a combination of factors.

This distinction is important before considering surgery.

When should surgery for persistent incontinence be considered?

Because natural recovery can continue for many months, treatment usually begins conservatively.

However, men with severe leakage, very limited improvement or a major effect on quality of life can be referred for specialist assessment before the end of the first year. There is no benefit in leaving a man unsupported when his symptoms are severe or clearly plateauing.

Persistent, bothersome stress incontinence at approximately 12 months should not simply be accepted as inevitable.

The main established surgical treatments are the male sling and artificial urinary sphincter.

Male sling surgery

A male sling is placed beneath the urethra to support and reposition it.

It is generally most suitable for men with mild or moderate stress incontinence who:

• retain some sphincter function;
• do not have severe leakage;
• do not have significant urethral scarring;
• have not had radiotherapy, or understand that previous radiotherapy may reduce the likelihood of success.

The operation does not require the man to operate a device.

A successful sling may substantially reduce leakage or allow a man to become pad-free. Results are generally less predictable in men with severe incontinence, previous pelvic radiotherapy or previous transurethral prostate surgery.

Artificial urinary sphincter

The artificial urinary sphincter is the established treatment for moderate or severe male stress incontinence.

The device normally consists of:

• a fluid-filled cuff placed around the urethra;
• a small control pump positioned in the scrotum;
• a pressure-regulating component placed beneath the abdominal wall.

The cuff remains closed most of the time to prevent leakage. When the man wishes to urinate, he squeezes the pump in the scrotum. This temporarily opens the cuff and allows urine to pass. The cuff then closes automatically.

The artificial urinary sphincter can be life-changing for appropriately selected men, but it is an implanted mechanical device rather than a permanent cure without maintenance.

Men need sufficient hand dexterity and understanding to operate it. They must also be aware of possible complications, including infection, erosion, mechanical failure and the need for revision or replacement surgery over time. Treatment is best undertaken in a specialist centre experienced in male continence surgery.

What about urethral bulking injections?

Bulking agents are injectable materials placed around the urethra in an attempt to improve closure.

Results for post-prostatectomy incontinence are generally less reliable and less durable than established surgical treatments.

NICE advises against injecting bulking agents into the distal urinary sphincter to treat stress incontinence following prostate cancer treatment. They should therefore not be presented as a routine alternative to a sling or artificial urinary sphincter.

Leakage during sexual activity

Some men experience urinary leakage during sexual arousal or orgasm after prostate surgery.

Leakage at orgasm is sometimes called climacturia. It may be embarrassing and can affect confidence, intimacy and willingness to resume sexual activity.

Men often do not volunteer this symptom unless they are asked directly. It is important to understand that it is a recognised consequence of treatment and not something that needs to be managed in silence.

Practical measures can include emptying the bladder before sexual activity, using a small pad or towel and, in selected cases, pelvic-floor or continence treatment. Persistent or distressing symptoms should be discussed with the clinical team.

The emotional effect of urinary incontinence

Urinary leakage is not merely a physical inconvenience.

It can affect:

• self-confidence;
• work;
• exercise;
• travel;
• sleep;
• social activity;
• clothing choices;
• sexual relationships;
• mood and mental wellbeing.

Some men withdraw from normal activities because they are worried about odour, visible leakage or access to toilets. Others feel embarrassed discussing the problem with partners, family members or clinicians.

These reactions are understandable, but support is available. Continence nurses, specialist physiotherapists, urologists and psychological-support services can all play a role.

Men should not be expected to accept a major loss of quality of life simply because their cancer treatment has been completed.

When should urgent medical advice be sought?

A man should seek urgent medical assessment if he develops:

• a sudden inability to pass urine;
• fever, shivering or feeling acutely unwell with urinary symptoms;
• significant blood in the urine;
• blood clots that interfere with urination;
• severe lower abdominal or pelvic pain;
• rapidly worsening symptoms.

A routine but prompt review should be arranged for:

• leakage that is not improving as expected;
• recurrent urinary infections;
• a persistently weak urinary stream;
• a feeling of incomplete bladder emptying;
• worsening urgency or frequency;
• increasing pad use;
• skin damage caused by leakage;
• symptoms affecting sleep, work, exercise, relationships or mental wellbeing.

Setting realistic expectations

Perhaps the most important message is that urinary leakage after prostate cancer treatment is usually manageable.

After radical prostatectomy, early leakage is common. It does not mean that the operation has failed or that the problem will necessarily be permanent. Most men experience progressive improvement, particularly during the first few months, and recovery may continue throughout the first year.

At the same time, men should receive honest information. A minority develop persistent incontinence, and the impact can be substantial. These men require assessment and treatment rather than reassurance alone.

The goal of prostate cancer treatment is first to achieve the best possible cancer control. Functional outcomes—including urinary control, sexual function and quality of life—are nevertheless central to good cancer care and should be discussed before treatment, reviewed afterwards and actively managed when problems arise.

Questions men may wish to ask before treatment

Before deciding on prostate cancer treatment, it may be helpful to ask:

• What type of urinary symptoms am I most likely to experience?
• What does your team mean when it reports a man as continent?
• How many men are completely pad-free after this treatment?
• How long does recovery usually take?
• Which personal factors may affect my recovery?
• Can the bladder neck, urethra and nerves be preserved safely in my case?
• When should I begin pelvic-floor exercises?
• Is specialist pelvic-health physiotherapy available?
• What support will I receive if leakage persists?
• When would referral to a continence surgeon be appropriate?

Clear answers to these questions can help set realistic expectations and allow treatment decisions to reflect what matters most to the individual man.

Frequently asked questions

A final perspective

Urinary incontinence is a legitimate concern for any man facing treatment for prostate cancer, but it should not be viewed as an inevitable permanent outcome.

For many men, leakage after surgery is temporary and improves steadily. For others, symptoms can be controlled with pelvic-floor work, bladder treatment and practical support. When significant stress incontinence persists, specialist surgical treatments can produce major improvements in confidence, independence and quality of life.

The key is to discuss urinary function openly, understand the likely course of recovery and seek assessment when progress is slower than expected.

No man should feel that he has to endure troublesome incontinence in silence.
