Ureters01:22

Ureters

1.5K
The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

Anatomy of the Genitourinary System I: Kidneys and Ureters

551
The upper urinary system comprises two kidneys and two ureters, which are crucial in filtering blood and forming urine.KidneysLocation and Structure:The kidneys are two bean-shaped organs positioned behind the peritoneum on either side of the spine.Kidneys are between the 12th thoracic (T12) and the 3rd lumbar (L3) vertebrae.The position of the liver causes the right kidney to sit slightly lower than the left.Protective Layers:Each kidney is enveloped in a tough, fibrous membrane called the...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

294
Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Kidney Structure

75.0K
The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

Summary
This summary is machine-generated.

Ectopic ureters occur in 3.5% of patients with anorectal malformations, often associated with renal dysfunction and increased risk of renal failure. Early identification is crucial for surgical planning and vigilant renal function monitoring.

Area of Science:

  • Pediatric Urology
  • Congenital Anomalies
  • Surgical Anatomy

Background:

  • Literature on ectopic ureters in anorectal malformations (ARMs) is limited.
  • ARM repair may involve dissection near ureteral insertion sites, risking injury.
  • Identifying ectopic ureters aids surgical planning and prevents intraoperative complications.

Purpose of the Study:

  • To determine the incidence and location of ectopic ureters in patients with ARMs.
  • To characterize associated renal anomalies and dysfunction.
  • To assess the impact of ureteral ectopia on renal outcomes.

Main Methods:

  • Retrospective review of patients with ARMs and ectopic ureters.
  • Data collected from a colorectal database.
  • IRB-approved study design.

Main Results:

  • 3.5% of 2283 ARM patients had ectopic ureters; 29% had bilateral.
  • Common ectopic sites: bladder neck (33%), vagina (15%), urethra (13%).
  • High rates of renal dysfunction (59% ipsilateral, 29% contralateral), renal failure (6%), and transplant (2.5%) in patients with ectopic ureters.

Conclusions:

  • Ectopic ureters are present in 3.5% of ARM patients, with higher incidence in cloaca and recto-bladder neck fistula.
  • Ureteral ectopia is linked to an increased risk of renal failure.
  • Preoperative identification and vigilant renal monitoring are essential for managing ARM patients with ectopic ureters.
