Hello,
Welcome to the ehealthforum and I am glad to help you. The enlargement of the prostate is the commonest cause of blood in urine in the elderly.
However, Iâll suggest consulting a urologist and getting yourself investigated. You might require a CT scan/Cystoscopy to rule out other causes like a stone in the urinary tract or bladder cancer.
Further treatment will depend upon the underlying diagnosis. Meanwhile, Iâll suggest drinking plenty of fluids which prevents the precipitation of a clot in the urinary tract. I sincerely hope that helps. Take care.
