• Urine dipstick: Quick initial test but needs confirmation.
• Urine microscopy: To quantify red cells and look for casts/cells.
• Ultrasound: Assess kidneys and bladder for masses, cysts, or stones.
• CT Urogram: Detailed imaging of the urinary tract.
• Cystoscopy: If bladder malignancy is suspected.

• Directed by the underlying cause.
• Antibiotics for UTIs, surgery or lithotripsy for stones, etc.
