What causes difficulty passing urine?
Benign prostatic enlargement
Weak stream, hesitancy, incomplete emptying and nocturia in men over 50.
Urethral stricture
Narrowing after infection, catheterisation or injury, causing a thin, slow stream.
Prostate cancer
May cause similar symptoms. Assessed with examination and PSA.
Bladder or pelvic floor dysfunction
Incomplete emptying without obstruction, in men and women.
Medication
Some antihistamines, decongestants and antidepressants precipitate retention.
How it is investigated
- ✓Uroflowmetry and post-void residual ultrasound
- ✓PSA and digital rectal examination in men
- ✓Urine culture and kidney function
- ✓Cystoscopy where a stricture is suspected
Not every patient needs every test. The consultation decides which of these apply to you.
Frequently asked questions
Does an enlarged prostate mean cancer?▼
No. Benign enlargement is extremely common with age and is not cancer, nor does it become cancer. The symptoms overlap, which is why assessment includes a PSA test and examination — but most men with these symptoms have a benign cause and respond well to medication.
What is acute urinary retention?▼
Being unable to pass urine at all while the bladder fills and becomes painful. It is an emergency — the bladder is drained with a catheter, which brings immediate relief and protects the kidneys. Do not wait it out overnight.
