Vesicoureteral reflux (VUR) is a condition where urine flows backward from the bladder into the ureters and sometimes up to the kidneys. This can lead to urinary tract infections (UTIs) and other complications. It’s most commonly seen in children but can also affect adults.

Pathophysiology

Structure

  1. Bladder: A hollow organ that stores urine.
  2. Ureters: Tubes that carry urine from the kidneys to the bladder.
  3. Kidneys: Organs that filter blood to produce urine.

Blood Supply

  • The blood supply to the kidneys comes from the renal arteries, which branch off the abdominal aorta.
  • The bladder is supplied by branches of the internal iliac artery.

Nerve Supply

  • The bladder is innervated by the autonomic nervous system, specifically the parasympathetic and sympathetic nerves, which control bladder contraction and relaxation.

Types of VUR

  1. Primary VUR: Caused by a congenital (present at birth) defect in the valve that connects the ureters to the bladder.
  2. Secondary VUR: Occurs due to other medical conditions, such as bladder obstruction or neurogenic bladder.

Causes of Vesicoureteral Reflux

Here are 20 potential causes of VUR:

  1. Congenital Anomalies: Abnormal development of the urinary tract.
  2. Urinary Tract Infections (UTIs): Can lead to inflammation and reflux.
  3. Bladder Dysfunction: Poor bladder function can cause urine to flow backward.
  4. Constipation: Can put pressure on the bladder, causing reflux.
  5. Neurological Disorders: Conditions like spina bifida can affect bladder control.
  6. Urinary Stones: Can block urine flow, causing reflux.
  7. Enlarged Prostate: In men, can obstruct urine flow.
  8. Pregnancy: Increased pressure on the bladder can lead to reflux.
  9. Vesicoureteral Obstruction: Blockage at the junction where the ureter meets the bladder.
  10. Abnormal Ureteral Insertion: If the ureters insert too low in the bladder.
  11. Ureterocele: A cystic dilation of the ureter near the bladder.
  12. Cystitis: Inflammation of the bladder.
  13. Anatomical Variations: Variations in urinary tract anatomy.
  14. Infections in the Kidneys: Such as pyelonephritis can contribute to reflux.
  15. Medications: Some can weaken bladder function.
  16. Previous Surgeries: On the urinary tract can lead to reflux.
  17. Obesity: Increased abdominal pressure can affect bladder function.
  18. Trauma: Injuries affecting the bladder or ureters.
  19. Gender: Females are at a higher risk due to anatomical differences.
  20. Family History: Genetic predisposition to urinary tract anomalies.
