Renal Pelvis Disorders

Renal pelvis disorders affect the part of the kidney where urine collects before moving to the ureter. Understanding these conditions can help in early detection, effective management, and prevention. This guide covers everything you need to know about renal pelvis disorders, including their causes, symptoms, diagnosis, treatment options, and more.

The renal pelvis is a funnel-shaped structure in the kidney that collects urine from the kidney’s filtering units (nephrons). From the renal pelvis, urine flows into the ureter, which transports it to the bladder for storage before elimination.

Pathophysiology

Structure

  • Renal Pelvis: Central area where urine accumulates.
  • Ureter: Tubes connecting kidneys to the bladder.
  • Calyces: Extensions from the renal pelvis that collect urine from nephrons.

Blood Supply

  • Renal Arteries: Supply oxygen-rich blood to the kidneys.
  • Renal Veins: Return filtered blood to the body.
  • Microcirculation: Ensures nutrients and oxygen reach renal tissues.

Nerve Supply

  • Autonomic Nervous System: Controls involuntary functions like urine flow.
  • Sensory Nerves: Detect pain and pressure changes in the kidney area.

Types of Renal Pelvis Disorders

  1. Hydronephrosis: Swelling of the kidney due to urine buildup.
  2. Renal Pelvis Stones (Nephrolithiasis): Kidney stones formed in the renal pelvis.
  3. Pelviureteric Junction (PUJ) Obstruction: Blockage where the renal pelvis meets the ureter.
