In a woman presenting with hematuria, flank pain, and a palpable mass, which diagnosis is most likely?

Explanation:
Renal cell carcinoma is most likely here because the classic presentation includes gross, painless hematuria, flank pain, and a palpable renal mass. This triad points to a tumor growing within the kidney that can bleed into the urinary tract and be felt as a mass on exam. The other conditions don’t typically produce all three features together. Bladder cancer often causes hematuria but not a palpable flank mass. Ureteropelvic junction obstruction can cause flank pain and hydronephrosis but usually not gross hematuria. Pyelonephritis presents with fever, chills, urinary symptoms, and costovertebral angle tenderness rather than a discrete abdominal mass.
