The short version
Urinary symptoms in men are common, and the prostate gets most of the blame. It is often involved, but not always. Getting up at night, urgency, leaking, and a weak stream can also come from the bladder, from medicines, from sleep apnea, from diabetes, or from how much and when you drink. This page covers the urinary problems beyond the prostate itself; for enlarged prostate (BPH), prostatitis, and PSA, see the prostate health guide.
| Problem | What it feels like | First steps |
|---|---|---|
| Nocturia | Waking two or more times a night to urinate | Look for causes outside the prostate, including sleep apnea |
| Overactive bladder | Sudden, hard-to-delay urges, with or without leaking | Bladder training, drink timing, then medicines |
| Leakage | Leaking with coughing, lifting, or after prostate treatment | Pelvic floor exercises |
| Urinary infection | Burning, frequency, sometimes fever | See a clinician; usually needs a urine test and antibiotics |
| Kidney stones | Severe cramping pain in the side or back, often with blood in the urine | Pain control, fluids, and a clinician's evaluation |
| Blood in the urine | Pink, red, or brown urine | Always get it checked |
Waking at night to urinate (nocturia)
Getting up once a night becomes normal with age; getting up two or more times is worth looking into because it fragments sleep and, in older men, raises the risk of nighttime falls. An enlarged prostate is one cause, but others are easy to miss:
- Sleep apnea. Apnea episodes trigger hormone changes that make the body produce more urine overnight. Treating apnea often reduces nighttime urination. See our sleep apnea guide.
- Evening fluids, caffeine, and alcohol, which increase urine output and irritate the bladder.
- Medicines, especially diuretics ("water pills") taken late in the day.
- Diabetes or high blood sugar, which pulls extra water into the urine (see blood sugar and metabolic health), and heart failure or leg swelling, where fluid collects in the legs by day and returns to circulation when lying down.
A simple 3-day bladder diary (what you drink, when you go, and how much) helps a clinician sort out the cause. Try moving fluids earlier in the day, cutting evening caffeine and alcohol, and elevating swollen legs in the afternoon.
Overactive bladder
Overactive bladder (OAB) means urgency, usually with frequent urination and sometimes leaking before you reach a toilet. The American Urological Association (AUA) guideline describes a stepwise approach:
- Behavior changes first: bladder training (gradually stretching the time between visits), timed toileting, pelvic floor exercises, limiting caffeine and alcohol, and weight loss if overweight.
- Medicines next: two families, antimuscarinics (such as oxybutynin or tolterodine) and beta-3 agonists (mirabegron or vibegron). Antimuscarinics can cause dry mouth and constipation, and in older adults they are linked to confusion and memory problems, so many prescribers prefer a beta-3 agonist for men over 65.
- Procedures for medicine failures: onabotulinumtoxinA (Botox) injected into the bladder, or nerve stimulation.
In men who also have BPH, OAB medicine is sometimes added to an alpha blocker, but prescribers watch for incomplete emptying, since a bladder that cannot empty can get worse on these medicines. Don't treat urgency on your own before ruling out an infection or retention.
Leakage and pelvic floor training
Stress leakage (a few drops when you cough, sneeze, or lift) is most common in men after prostate surgery or radiation, but it also occurs with age and obesity. Pelvic floor muscle training, often called Kegels, is the first-line treatment. The key is doing them correctly: tighten the muscles you would use to stop urine midstream, without squeezing the buttocks or holding your breath, and hold for a few seconds, repeated several times a day. A pelvic floor physical therapist can check technique, and results usually take weeks to months. For persistent leakage, options include male slings and artificial urinary sphincters.
Urinary tract infections in men
UTIs are less common in men than in women, and when they happen in men they are treated more carefully because they can involve the prostate or point to an underlying problem such as incomplete emptying or stones. Symptoms include burning, frequency, urgency, cloudy or foul-smelling urine, and lower belly pain. Fever, chills, flank pain, or an inability to urinate need same-day care. Don't use leftover antibiotics: a clinician should confirm the infection with a urine test and choose the drug and duration.
Kidney stones
Kidney stones are hard mineral deposits that form in the kidney, and they are more common in men than in women. A stone that moves into the ureter causes sudden, severe, wave-like pain in the side or back that can radiate to the groin, often with nausea and blood in the urine. Small stones often pass on their own with fluids and pain control; stones that are large, cause infection, or block urine flow need a procedure.
The main prevention step is fluid. The AUA guideline advises drinking enough to produce at least about 2.5 liters of urine a day. Other measures depend on the stone type, which a lab analysis of the stone or a 24-hour urine test can identify. Usual advice includes keeping sodium low, getting normal (not high) dietary calcium, and not overdoing animal protein. Get care at once for stone pain with fever, vomiting you cannot control, or no urine output.
Blood in the urine
Visible blood in the urine should always be evaluated, even if it happens once and goes away. Many causes are minor, such as infection, stones, or an enlarged prostate, but it can also be the first sign of bladder or kidney cancer. Bladder cancer is more common in men than in women, and smoking is its biggest risk factor. A typical work-up includes a urine test, imaging, and often a look inside the bladder (cystoscopy). Blood thinners do not explain blood in the urine on their own and should not be assumed to be the cause.
Medicines that can make things worse
- Decongestants (pseudoephedrine, phenylephrine) tighten the bladder outlet and can cause retention in men with BPH.
- Older antihistamines (diphenhydramine, found in many "PM" sleep aids) can slow bladder emptying. See our sleep aids guide for alternatives.
- Diuretics increase urine output; timing matters.
- Some antidepressants and opioids can reduce bladder emptying.
Don't stop a prescribed medicine on your own; ask your prescriber whether timing or an alternative would help.
When to see a doctor
Get care right away for:
- !Not being able to urinate, or a painfully full bladder.
- !Urinary symptoms with fever, chills, or back/flank pain.
- !Severe side or back pain with nausea or vomiting.
- !Any visible blood in the urine.
Make a regular appointment if nighttime urination, urgency, leaking, or a weak stream is disturbing your sleep or daily life. Bring your bladder diary and a list of all medicines, including over-the-counter ones.
