Urinary tract infection (UTI) cannot be solely diagnosed on the basis of medical history. Certain simple investigations are required to confirm a diagnosis:
- Routine examination of urine: Analyzing a urine sample in a laboratory helps to detect the presence of bacteria, red blood cells and pus in urine.
- Urine culture: If there is persistent pain with high fever, microbial culture of urine and a sensitivity test are done to identify the pathogens.
- Ultrasonography of Abdomen: A sonography helps to rule out any kidney stones or enlarged prostate.
- Intravenous pyelogram (IVP): In some cases, if the infection does not get cleared by medication, an IVP needs to be performed to determine if any structural abnormalities are present.
- Cystoscope: It is used to visualize the internal structure of bladder for any abnormalities.
