Frequently asked questions
Is painless blood in urine serious?
It must always be investigated, as it can be an early sign of a bladder or kidney tumour — even if it happens only once and without pain.
When should men check their prostate?
Discuss PSA testing with a urologist if you have urinary symptoms (weak stream, night-time frequency) or from around age 50 (earlier with family history).
