A condition in which both kidneys are fused in the same quadrant with two separate collecting systems and two normally located adrenal glands is called?

A condition in which both kidneys are fused in the same quadrant with two separate collecting systems and two normally located adrenal glands is called?

• A. Polycystic kidney disease
• B. Horseshoe kidney
• C. Crossed fused ectopia
• D. Renal agenesis

Answer: (C)

Renal fusion anomalies are about kidneys developing in unusual ways and ending up in unexpected positions. The scenario described is crossed fused ectopia: both kidneys lie on the same side in one quadrant and are fused together, yet each kidney retains its own collecting system and ureter, and the adrenal glands remain in their normal positions atop the kidneys. This pattern—two kidneys fused into a single mass on one side with two separate collecting systems and normal adrenals—distinguishes it from other conditions. For example, a horseshoe kidney also involves fusion, but the kidneys are located lower in the abdomen across the midline and are not confined to one quadrant; renal agenesis means absence of one or both kidneys, and polycystic kidney disease features multiple cysts rather than fused kidneys.
