Urinary hesitancy

Urinary hesitancy is trouble starting to urinate — there is a pause or delay before the flow begins, and you may need to wait, relax or strain to get it going. It is one of the 'obstructive' lower urinary tract symptoms and usually comes together with a weak stream, dribbling and a sense of incomplete emptying. In men, the leading cause by far is benign prostate enlargement (BPH): the enlarging prostate presses on the urethra where it leaves the bladder, so it takes more effort and time to overcome the resistance and start the flow. Prostate inflammation or infection (prostatitis) can cause hesitancy too, often with pain and other urinary symptoms. A urethral stricture (a scarred narrowing) obstructs the outflow mechanically. Hesitancy can also arise when the bladder muscle is weak — from nerve conditions, diabetes affecting the nerves, or the after-effects of long-standing obstruction — so it cannot generate a prompt, forceful stream. Certain medicines (including some cold remedies and drugs with anticholinergic effects) can worsen it. Because a treatable enlarged prostate is the usual cause, but the picture overlaps with infection and rarer problems, persistent hesitancy is worth assessing — and sudden inability to pass urine at all is an emergency.

• Enlarged prostate (BPH) — the leading cause in men, with a weak stream and incomplete emptying.
• Prostatitis — inflammation or infection of the prostate, often with pain.
• Urethral stricture — a scarred narrowing obstructing flow.
• Weakened bladder muscle — from nerve problems, diabetes or long-standing obstruction.
• Certain medicines — some cold remedies and anticholinergic drugs.
• Prostate cancer — an uncommon cause, part of the assessment.

Urinary hesitancy, especially in a man, is assessed with a prostate-focused work-up. A urinalysis and sometimes a urine culture look for infection. PSA is often measured to help assess the prostate, read alongside age and examination. Kidney function (creatinine) is checked if obstruction may be backing up to the kidneys, and how well the bladder empties may be measured. A review of medications can reveal a drug worsening the symptom. Mediora.AI can surface a raised PSA or infection from your results that relates to the prostate and outflow; the assessment, including examining the prostate, belongs with your doctor.
