What type of urine findings is expected in a child with postinfectious glomerulonephritis?

• A. Clear urine with low specific gravity
• B. Moderate hematuria and proteinuria
• C. High levels of glucose
• D. Presence of crystals

Answer: (B)

In postinfectious glomerulonephritis, which often follows a streptococcal infection, the typical urine findings include moderate hematuria and proteinuria. Hematuria refers to the presence of blood in the urine, while proteinuria indicates an abnormal amount of protein. This condition is characterized by the inflammation of the glomeruli, which leads to a change in the filtering capability of the kidneys, allowing both red blood cells and protein to leak into the urine. The presence of these findings is due to the immune response triggered by the prior infection, which leads to damage and alteration in kidney function. This is distinct from other types of urine findings that might present with clear urine, low specific gravity, or abnormal glucose levels, which are not characteristic of postinfectious glomerulonephritis. Additionally, the presence of crystals typically points to other urinary tract issues and is not associated with this specific condition.
