Nephroptosis

Nephroptosis, also known as “floating kidney,” is a condition where the kidney moves down into the pelvis when a person stands up from a lying or sitting position. Normally, kidneys stay in place thanks to surrounding tissues. However, in nephroptosis, the kidney drops more than 5 centimeters, which can cause various symptoms and complications.

Pathophysiology of Nephroptosis

Structure

• Kidney Anatomy: Each person has two kidneys located on either side of the spine, just below the rib cage. They are held in place by connective tissues, fat, and blood vessels.
• Support Tissues: Ligaments and the renal fascia (a fibrous tissue) help keep the kidneys stable.

Blood Supply

• Renal Arteries and Veins: These vessels supply blood to and from the kidneys. Proper blood flow is essential for kidney function.
• Vascular Changes: In nephroptosis, the movement of the kidney can stretch or compress blood vessels, potentially affecting blood flow.

Nerve Supply

• Renal Nerves: These nerves control various kidney functions, including blood flow and hormone release.
• Nerve Impact: Movement of the kidney may irritate nearby nerves, leading to pain or other neurological symptoms.

Types of Nephroptosis

1. Superior Nephroptosis: Kidney moves upward instead of downward.
2. Chronic Nephroptosis: Long-term condition with persistent symptoms.
3. Acute Nephroptosis: Sudden onset, often after significant weight loss or rapid growth.
