A 62-year-old man reporting facial edema and acute hematuria likely has what diagnosis?

The likely diagnosis for a 62-year-old man presenting with facial edema and acute hematuria is acute poststreptococcal glomerulonephritis. This condition is characterized by the onset of glomerular inflammation following an infection, particularly a streptococcal throat or skin infection. The symptoms of facial edema, often due to fluid retention, and hematuria, which is the presence of blood in the urine, are classic manifestations of this renal condition.

In acute poststreptococcal glomerulonephritis, the inflammation of the glomeruli affects the kidney's ability to filter blood effectively, leading to symptoms such as edema and hematuria, along with potential proteinuria and hypertension. The demographic mentioned—specifically a 62-year-old male—can be consistent with the cold cases of this condition, though it is more common in children.

Other conditions like minimal change disease primarily lead to significant proteinuria and edema but typically do not present with hematuria, particularly in this age group. Chronic kidney disease could cause edema; however, it usually presents with a more gradual decline in renal function rather than acute symptoms of hematuria. Lastly, a urinary tract infection may cause hematuria
