Which symptom is associated with glomerulonephritis?

Hematuria, or the presence of blood in the urine, is a hallmark symptom of glomerulonephritis. This condition involves inflammation of the glomeruli, the tiny filtering units within the kidneys. This inflammation can lead to increased permeability of the glomerular membranes, allowing red blood cells to leak into the urine. As a result, patients often exhibit hematuria, which can vary from microscopic blood that is only detectable through laboratory testing to gross hematuria, where the blood is visible to the naked eye.

Understanding the context of hematuria in glomerulonephritis is essential for clinicians. It indicates underlying kidney pathology that may require further investigation, such as imaging studies or a kidney biopsy, to determine the specific cause of the glomerulonephritis, whether it's due to autoimmune conditions, infections, or other systemic diseases.

While hypertension, dysuria, and polyuria can be associated with various renal or urinary tract conditions, they are not as directly indicative of glomerulonephritis itself compared to hematuria. Hypertension might develop as a secondary effect of kidney dysfunction, dysuria is more typically linked with urinary tract infections, and polyuria may indicate different disorders like diabetes or hypercalcemia
