Prostate Cancer Incontinence: What to Know

Urine leakage may happen with coughing, laughing, lifting, walking, or a sudden urge to pass urine. Some people notice dribbling, while others cannot hold urine long enough to reach a toilet. Prostate cancer itself can affect urinary flow when the prostate or nearby disease presses on the urinary passage. Difficulty passing urine can also occur, and needs assessment because blockage and infection are possible explanations as well as cancer-related changes.

Treatment can change bladder control. Prostate removal surgery may temporarily weaken the muscles and support structures that help retain urine. Radiotherapy can irritate the bladder or urinary passage during or after treatment. The pattern may change over time, so record when leakage happens, how much urine is lost, and whether urgency, burning, blood, fever, or pain is present.

Tell your cancer team about leakage rather than waiting for it to become severe. They may review medicines, test a urine sample, check bladder emptying, and refer you to a continence or pelvic-floor specialist. Pelvic-floor exercises can help some people when taught and timed appropriately; a specialist can check that you are using the right muscles.

Keep a brief bladder diary, plan toilet access, and use absorbent products if needed. Avoid changing fluid intake drastically unless your clinician advises it. Ask before restricting drinks, because concentrated urine can irritate the bladder and dehydration can create other problems. Treatment options depend on the cause and may include rehabilitation, medicines, devices, or a procedure.

Contact your oncology or urology team promptly if leakage is new, worsening, or interfering with sleep, work, skin care, or daily activities. Seek urgent medical help if you cannot pass urine, have severe lower-abdominal pain, heavy blood in the urine, fever with urinary symptoms, confusion, or sudden weakness. These signs can indicate retention, infection, bleeding, or another problem needing timely assessment.

Ask what is most likely causing your leakage, whether your bladder is emptying fully, and which symptoms should trigger an urgent call. You can also ask when to begin pelvic-floor training, whether your current medicines affect bladder control, and which continence products or specialist services are available.
