A megaureter is a condition where one or both ureters, the tubes that carry urine from the kidneys to the bladder, become abnormally enlarged or dilated. This can lead to various complications, including urinary obstruction, kidney damage, and infections.
Pathophysiology
Structure: The ureter consists of three layers:
- Mucosa: The inner lining that produces mucus.
- Muscularis: The middle layer that contracts to move urine.
- Adventitia: The outer layer that connects the ureter to surrounding tissues.
Blood Supply: The ureters receive blood from several arteries, primarily:
- Renal arteries (from the kidneys)
- Gonadal arteries
- Abdominal aorta
Nerve Supply: The ureters are innervated by autonomic nerves from the sympathetic and parasympathetic systems. This nerve supply helps coordinate the muscular contractions necessary for urine transport.
Types of Megaureter
- Congenital Megaureter: Present at birth, often due to a developmental issue.
- Acquired Megaureter: Develops later in life due to factors like obstruction or injury.
- Unilateral Megaureter: Affects one ureter.
- Bilateral Megaureter: Affects both ureters.
Causes of Megaureter
- Congenital Anomalies: Abnormal development during pregnancy.
- Obstruction: Blockages from stones or tumors.
- Reflux: Backflow of urine from the bladder into the ureters.
- Infection: Recurrent urinary tract infections (UTIs).
- Neurological Disorders: Conditions that affect nerve function, leading to poor muscle control.
- Scarring: From previous surgeries or injuries.
- Inflammation: Conditions like ureteritis or cystitis.
- Radiation Therapy: Can cause damage to the ureters.
- Vascular Compression: Nearby blood vessels may compress the ureters.
- Kidney Stones: Can cause blockage and swelling.
- Prostate Enlargement: In men, can affect the urinary tract.
- Pregnancy: Hormonal changes can lead to temporary ureter dilation.
- Diabetes: May contribute to nerve damage affecting urine flow.
- Chronic Constipation: Can put pressure on the urinary tract.
- Pelvic Masses: Tumors in the pelvis can obstruct ureteral flow.
- Endometriosis: Tissue growth outside the uterus can compress the ureters.
- Fibrosis: Scar tissue can narrow or block ureters.
- Idiopathic: No identifiable cause in some cases.
- Lymphadenopathy: Enlarged lymph nodes can press against the ureters.
- Anomalous Ureteral Insertions: Ureters might not connect properly to the bladder.
