[/INST] Hi.Thanks for your query.Read the history and understood your problem.The history of an injury to the back in a boat and starting of hematuria (blood in urine) after 4 days is indicative of trauma to the kidney. I would advise you the following :- Admission to the hospital.-Urgent ultrasonography of the while abdomen.-Tests of blood: Blood group as you may need blood anytime, CBC, kidney function tests.-Urine: routine, microscopy, culture and sensitivity.-CT Scan and intravenous Pyelography to see the status of the kidney.-Rest of the treatment under the guidance of the Urologist. </s>
