**Core Concept**
The underlying condition in this patient is likely a severe form of hypertension with renal involvement, leading to a specific clinical syndrome characterized by high blood pressure, edema, and hematuria.

**Why the Correct Answer is Right**
The patient's presentation is suggestive of nephrotic syndrome with severe hypertension, which is a hallmark of kidney disease. The gross hematuria and absent ascites point towards a renal cause rather than a primary cardiac or liver condition. The presence of pedal and facial edema is indicative of fluid overload, a common complication of nephrotic syndrome. This condition is often associated with minimal change disease, but the presence of hypertension and gross hematuria might suggest a more severe or complicated renal pathology such as membranous nephropathy or focal segmental glomerulosclerosis.
