IgA nephropathy is divided into five stages pathologically, with stage three being the focal proliferative type. The higher the stage, the more severe the condition of IgA nephropathy. Stage three is in the early to middle phase, where generally the condition of the patients is comparatively good, and rarely worsens to uremia, belonging to the low-risk group. Clinically, patients with stage three IgA nephropathy often exhibit repeated occurrences of gross hematuria or persistent microscopic hematuria. Some patients may also experience varying degrees of increased urinary protein. Patients with this stage of IgA nephropathy rarely suffer from hypertension or renal insufficiency, but it is essential in daily life to avoid nephrotoxic drugs, prevent infections, seek medical attention promptly upon infection, and regularly follow up on routine urine and renal function changes. If the condition tends to worsen, active treatment should be pursued.
