What clinical finding is NOT associated with post-streptococcal glomerulonephritis (PSGN)?

Post-streptococcal glomerulonephritis (PSGN) is a kidney condition that can occur after an infection with certain strains of Streptococcus bacteria, commonly following a throat or skin infection. The clinical findings associated with PSGN typically center around the glomerular injury resulting from the body's immune response to the streptococcal infection.

Hematuria, the presence of blood in the urine, is a classic finding in PSGN, resulting from glomerular inflammation and damage to the filtration barrier. Proteinuria, or the presence of excess protein in the urine, also commonly occurs due to the same inflammatory processes affecting the glomeruli, leading to increased permeability. Hypertension is frequently observed as well, as the kidney's ability to regulate fluid and electrolyte balance becomes impaired following glomerular injury, contributing to increased blood pressure.

On the other hand, a firm abdominal mass is not a recognized feature of PSGN. While abdominal symptoms can arise in various conditions, the typical manifestations of PSGN relate specifically to changes in urinary output and systemic blood pressure rather than the presence of palpable abdominal masses. This distinguishes option A from the other findings typically seen in patients with post-streptococcal glomerulone
