Ureters01:22

Ureters

1.7K
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

647
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

365
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 Structure01:45

Kidney Structure

75.3K
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.

Frequency-dependent Selection01:21

Frequency-dependent Selection

24.1K
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Gene Evolution - Fast or Slow?02:05

Gene Evolution - Fast or Slow?

8.2K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Area of Science:

  • Urology
  • Congenital Anomalies
  • Pediatric Nephrology

Background:

  • Ureter triplication is an extremely rare congenital anomaly, with fewer than 100 reported cases since 1870.
  • This condition is classified into four types and frequently co-occurs with other urological abnormalities.

Purpose of the Study:

  • To report a rare case of pediatric Type III ureter triplication.
  • To describe associated urological anomalies and diagnostic findings in a pediatric patient.

Main Methods:

  • Diagnosis utilized multislice computed tomography (CT).
  • Confirmation of the diagnosis was achieved intra-operatively.

Main Results:

  • A pediatric patient presented with Type III ureter triplication.
  • The condition was associated with ipsilateral vesicoureteral reflux and contralateral idiopathic renal atrophy.
  • The anomaly was identified during work-up for kidney transplantation.

Conclusions:

  • Ureter triplication, though rare, can present with significant associated urological anomalies.
  • Multislice CT is an effective diagnostic tool for identifying complex ureteral anomalies.
  • Early diagnosis and management are crucial, especially in pediatric patients undergoing transplant evaluation.
