Difficulty starting to urinate

Category: Urinary & Kidneys · All urinary symptoms

What it can feel like

Difficulty starting to urinate (hesitancy) means standing and waiting for the stream to begin, sometimes needing to strain. In men it is most often the prostate squeezing the water pipe as it enlarges with age; because it reflects obstructed flow, it is usually assessed together with stream strength and emptying.

Possible causes

A symptom can have many causes, and most are not serious. The lists below group conditions this symptom can be associated with — common causes first. They are possibilities to discuss with a clinician, not a diagnosis.

Common causes

Hesitancy can be associated with prostate enlargement, constipation, anxiety about public toilets (shy bladder), and medicines including some antidepressants, decongestants and painkillers.

Other possible causes

Hesitancy can also be associated with a narrowing of the water pipe (urethral stricture), prostate or bladder conditions, and neurological problems affecting bladder coordination.

Red flags — when to seek help promptly

Being unable to pass urine at all, with a painful, full bladder — urgent
Difficulty starting together with blood in the urine
Hesitancy with fever, side pain or vomiting
Hesitancy with leg weakness or saddle numbness

What a clinician may do

A clinician will ask about the full pattern of urinary symptoms, examine the abdomen and prostate, and test urine. A flow-rate test and bladder scan for leftover urine, blood tests including prostate-specific antigen (PSA) where appropriate, and sometimes pressure studies complete the picture.

Frequently asked questions

What does a bladder scan after urinating show?

It measures how much urine is left behind. A bladder that empties poorly is at risk of infection and, over time, back-pressure damage to the kidneys — so the leftover volume guides whether treatment is watchful, medical or surgical.

Is hesitancy always the prostate in men?

It is the commonest cause, but not the only one — strictures, medicines, constipation and bladder muscle problems all feature. The examination and flow tests separate obstruction (pipe problem) from a weak bladder pump.
