Hi,
Welcome to the ehealthforum and I am really glad to help you out. Smell during urination can be due to dehydration, urinary tract infection, hepatic or liver disease or rectal fistula. I would suggest you to get complete urine examination and urine for culture examination done. Also drink plenty of fluids and water and citric juices like cranberry juice. If the symptoms persist then please get these possibilities ruled out from a physician.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
