Prolapse of a kidney, also known as 'floating kidney', is called which term?

• A. Renal colic
• B. Nephropyrosis
• C. Nephroptosis
• D. Nephritis

Answer: (C)

Nephroptosis is the term for prolapse of the kidney, or a “floating kidney.” It happens when the kidney drops downward more than normal when you stand, usually because the surrounding fat and connective tissues that hold it in place have thinned or laxed. This downward movement can kink the ureter or twist the renal pelvis, leading to flank pain or urinary symptoms that are often worse in an upright position and improve when lying down. Other terms describe different kidney problems. Renal colic is the intense pain from kidney stones, not from the kidney’s position. Nephropyrosis (or pyonephrosis) involves pus in the kidney due to obstruction or infection, not prolapse. Nephritis refers to inflammation of the kidney, which is a separate issue from displacement.
