Ureterocele

Pathophysiology of Ureterocele

1.1. Structure:

• The ureter is a tube that carries urine from the kidney? to the bladder. In ureterocele, part of this tube bulges into the bladder, creating a balloon-like sac.
• Ureterocele primarily affects the lower end of the ureter, often narrowing the opening of the ureter where it meets the bladder.

1.2. Blood Supply:

• The ureter receives blood supply from branches of the renal?, common iliac, and internal iliac arteries?.
• The surrounding bladder tissues also receive blood from the superior and inferior vesical arteries, which ensure the flow of oxygen and nutrients to the region.

1.3. Nerve Supply:

• The ureter and bladder are supplied by sympathetic and parasympathetic nerves.
• The sympathetic nerves arise from the T10 to L2 spinal cord? segments, while parasympathetic nerves originate from the S2 to S4 segments.
• These nerves control bladder function, ureter contractions, and the sensation of urine passage.

Types of Ureterocele

1. Simple Ureterocele:
   • Involves only one ureter and is typically confined within the bladder.
2. Ectopic Ureterocele:
   • Extends beyond the bladder and may even protrude into the urethra?.
3. Intravesical Ureterocele:
   • Located entirely within the bladder and does not extend beyond it.
4. Extravesical Ureterocele:
   • Part of the ureterocele extends outside the bladder wall.
5. Unilateral? Ureterocele:
   • Occurs on one side of the body, affecting one ureter.
6. Bilateral? Ureterocele:
   • Affects both ureters?, present on both sides of the body.
7. Obstructive Ureterocele:
   • Blocks the flow of urine, leading to urinary retention?.
8. Non-obstructive Ureterocele:
   • Does not obstruct the urine flow, but may still cause urine reflux into the kidneys?.

Causes of Ureterocele

1. Congenital malformations during fetal development.
2. Duplication of the ureter (double ureter).
3. Genetic? mutations.
