Final answer:
Renal artery stenosis is not commonly associated with microscopic hematuria, while kidney stones, bladder cancer, and acute pyelonephritis are conditions that can present with this symptom.
Step-by-step explanation:
The differential diagnoses of microscopic hematuria commonly include conditions such as kidney stones, bladder cancer, and acute pyelonephritis. However, renal artery stenosis is not typically associated with microscopic hematuria as a direct symptom. Microscopic hematuria is the presence of red blood cells (RBC) in the urine, which can be indicative of a variety of renal and urological conditions, whereas renal artery stenosis is a condition characterized by the narrowing of one or both renal arteries that typically leads to hypertension and can contribute to chronic kidney disease but does not commonly cause hematuria.
