A 47-year-old client is being seen at the clinic after being seen in the emergency room last week for abdominal pain. While the client was in the emergency room, an ultrasound was performed and reveals a 6 mm obstructive renal calculi in the left ureter. While the nurse is collecting data, the client states, "My pain is still sharp, radiates to my groin and hurting more every time I try to move at work. When I urinate, it looks like there is blood in it too. I can't take this much longer. A random urinalysis is collected today which reveals 2+ hematuria and is positive for leukocytes. The nurse suspects that the client is experiencing which health alteration?
Select one:

A. Glomerulonephritis usually presents with symptoms such as facial edema, hypertension, and dark (cola-colored) urine. It is not typically associated with sharp, radiating pain or known obstructive renal calculi.
B. Hydronephrosis is the correct Answer. It occurs when a urinary tract obstruction (such as a 6 mm renal calculus) leads to urine buildup and swelling in the kidney. The client’s sharp, radiating pain, hematuria, and presence of leukocytes in the urine strongly support this diagnosis.
C. Inguinal hernia may cause groin pain or bulging, but does not explain hematuria, leukocyturia, or the findings of an obstructive renal stone.
D. Posterior urethral valvitis is a rare congenital condition typically seen in male infants and young boys, not in a 47-year-old adult male, making it an unlikely diagnosis.
