Prior to chemical tests for glycosuria, clinicians checked for sweetness of the urine as a sign of
A. pyelitis
Pyelitis is an infection of the renal pelvis and does not cause sweet-smelling urine.
B. diabetes mellitus
Diabetes mellitus often causes glycosuria (glucose in urine), which can make urine taste sweet.
C. renal calculus
Renal calculus (kidney stones) does not affect urine sweetness.
D. acute glomerulonephritis
Acute glomerulonephritis affects kidney function and urine appearance but does not specifically cause sweet-smelling urine.
