Hello... Welcome to healthcare magic.. According to your complain you have problem of change in colour of urine and foul smell that may be because of urinary tract infection or other problems... Do a urine test and microscopic examination for diagnosis... After urine culture test if infection is present than start proper antibiotics under doctor s suggestion... Consult a nephrologist for further diagnosis... Drink more water per day.... Maintain proper hygiene... More water dilute a urine and flush out a bacteria... Kidney infection or prostate problem also cause blood in urine..... Detail history and investigation helpful for diagnosis... I hope my guidance helpful to you... Take care... Thank you.
