Benign Prostatic Hyperplasia (BPH)

Benign prostatic hyperplasia is a non-cancerous enlargement of the prostate that can narrow the urine channel.

The prostate sits below the bladder and surrounds part of the urethra, the tube that carries urine out. As the gland enlarges, urine flow may become slower or the bladder may need to work harder. BPH and prostate cancer are different conditions, although urinary symptoms still deserve proper assessment.

Difficulty passing urine, frequent urination and urinary urgency are very common presentations of BPH. A weak stream, straining, a stop-start flow, dribbling afterward, or waking from sleep to urinate can also occur. Some people feel that the bladder has not emptied fully.

Seek urgent care if you cannot pass urine, have fever with urinary symptoms, develop severe lower abdominal pain, or pass visible blood in urine. These symptoms need timely assessment regardless of their cause.

BPH is linked to age-related changes in the prostate and hormone signalling. The prostate can grow gradually over time, but gland size alone does not predict how troublesome symptoms will be. Bladder function, medicines, constipation, fluid intake and other urinary conditions can influence the symptom pattern.

Symptoms may remain mild, fluctuate, or become more disruptive over time. Delaying urination because of travel or work can make urgency harder to manage, while drinking large volumes late in the evening may increase night-time trips. A review is helpful when the pattern changes rather than assuming it is solely due to BPH.

Ageing is the main background factor for BPH. A family history of prostate enlargement and some long-term health conditions may also be relevant. Clinicians will consider medicines that can affect bladder emptying, including some cold remedies and drugs with anticholinergic effects.

Assessment usually starts with a discussion of symptoms, medicines and medical history. A clinician may examine the abdomen and perform a prostate examination when appropriate. A urine test can look for blood, infection or other changes that might explain urinary symptoms. Further tests may assess urine flow, retained urine, kidney function or the prostate depending on the findings.

Management is matched to symptom burden, examination findings and personal priorities. Mild symptoms may be managed with monitoring and changes to drinking habits. Medicines can relax prostate and bladder-neck muscle or reduce prostate size in selected people. Procedures may be discussed when symptoms are severe, complications occur, or medicine is unsuitable.

A GP consultation can help organise the first assessment and decide whether specialist urology input is needed.

Spread fluids through the day rather than drinking a large amount at once, and consider reducing caffeine or alcohol if either worsens urgency. Empty the bladder before a long journey, allow enough time at the toilet, and treat constipation. Do not stop prescribed medicines without discussing them with a clinician.

Incomplete emptying can contribute to urinary retention, repeated urinary infection, bladder stones or pressure on the urinary tract. These outcomes are reasons for clinical follow-up, especially when symptoms are worsening or urine flow changes suddenly.

A urology referral may be appropriate for persistent troublesome symptoms, recurrent retention, recurrent infection, blood in urine, abnormal examination findings, or a need to discuss procedural treatment. The referral decision is based on the whole clinical picture.
