Urinary Tract Infection (UTI): The presence of leukocytes and blood in the urine, along with symptoms of hematuria and cloudy urine, strongly suggests a UTI. The duration of symptoms (2 weeks) could indicate a more chronic or complicated infection.

Kidney Stones: The presence of blood in the urine (hematuria) is a common symptom of kidney stones. Although kidney stones typically cause severe pain, some patients may present with minimal or no pain, especially if the stone is small or not obstructing the urinary tract.
Prostatitis: Inflammation of the prostate gland can cause urinary symptoms, including hematuria and cloudy urine, especially in older males. The presence of leukocytes in the urine supports an infectious or inflammatory process.
Bladder Cancer: Although less common, bladder cancer should be considered in the differential diagnosis, especially in older adults presenting with hematuria. The cloudy urine could be due to tumor-related bleeding or associated infection.

Sepsis from a Urinary Source: While less likely, sepsis originating from a urinary infection is a potentially life-threatening condition that must be considered, especially if the patient shows signs of systemic illness (fever, hypotension, altered mental status).
Obstructive Uropathy: Any condition causing obstruction of the urinary tract (e.g., kidney stones, tumors) can lead to severe complications, including renal failure, if not promptly addressed.

Tuberculosis of the Urinary Tract: Although rare in many parts of the world, genitourinary tuberculosis can cause chronic urinary symptoms, including hematuria and cloudy urine. A high index of suspicion is required, especially in patients with risk factors for tuberculosis.
Schistosomiasis: In patients from or traveling to endemic areas, schistosomiasis can cause urinary symptoms, including hematuria, due to the parasitic infection of the urinary tract.
