Urinary Symptoms (LUTS)

Storage symptoms reflect how the bladder holds urine — urinary urgency, frequency, needing to pass urine at night (nocturia) and urge incontinence. Voiding symptoms reflect how urine passes out of the bladder — a weak or interrupted stream, hesitancy in starting to urinate, needing to strain, and a feeling of incomplete emptying. Many men have a combination of both.

The most common cause of voiding symptoms in men is benign prostatic enlargement (BPH), which obstructs the flow of urine. Storage symptoms are most often due to overactive bladder. Other causes include urinary tract infection, prostatitis, urethral stricture, bladder stones, neurological conditions (such as stroke, Parkinson's, MS or spinal cord injury), and — less commonly — bladder or prostate cancer. Accurate diagnosis is essential because treatment differs by cause.

Waking once a night to pass urine is very common and often not a concern. Waking twice or more per night that is bothersome or disrupts sleep is worth investigating, and can usually be improved. Contributors include an enlarged prostate, overactive bladder, high fluid or caffeine intake late in the evening, and medical conditions such as heart failure or sleep apnoea. A bladder diary can help identify the pattern.

A specialist assessment typically starts with a symptom history (often using the IPSS questionnaire), a physical examination including a DRE, and simple investigations: urine dipstick and culture, a PSA blood test, uroflowmetry, a post-void residual bladder scan, and a 2–3 day bladder diary. Where indicated, further tests include flexible cystoscopy, video-urodynamic studies, and upper tract imaging.

Simple lifestyle changes can produce meaningful improvement, particularly for mild-to-moderate symptoms. These include fluid management (the right amount at the right times), reducing caffeine and alcohol, bladder training to gradually extend the interval between passing urine, and pelvic floor exercises. These are often the first step before medication is considered.

Choice depends on the pattern of symptoms. Alpha-blockers (such as tamsulosin) relax the prostate and bladder neck to improve flow. 5-alpha reductase inhibitors (such as finasteride) shrink the prostate over several months. Anticholinergics (solifenacin, tolterodine) and beta-3 agonists (mirabegron, vibegron) reduce bladder overactivity and urgency. Combinations may be used where both storage and voiding symptoms are present.

Surgery is usually reserved for significant prostatic obstruction that has not responded to medication, or for specific structural causes. Options include established gold-standard procedures such as TURP and HoLEP for very large prostates, and a range of minimally invasive alternatives — Aquablation, Rezum and stent (iTIND) — which may offer fewer side effects (such as retrograde ejaculation) and a quicker return to normal activity, though generally less durable than the surgical options.

Inability to pass urine (acute urinary retention) requires immediate assessment — attend A&E without delay. Other red flags that warrant urgent specialist review include blood in the urine (whether visible or picked up on a dipstick), severe pelvic pain with fever, or a rapid deterioration in symptoms. For non-urgent symptoms that are affecting daily life, book a specialist consultation for prompt assessment.
