Microanatomy of the intravesical ureter in children with and without reflux

Insights

Microscopic examination of children's ureters revealed no significant differences in fibrosis or inflammation between those with recurrent urinary tract infections and vesicoureteral reflux and those without. This suggests these conditions may not cause distinct ureteral tissue changes detectable microscopically.

Area of Science:

  • Pediatric Urology
  • Pathology
  • Nephrology

Background:

  • Recurrent urinary tract infections (UTIs) and vesicoureteral reflux (VUR) are common in children.
  • The long-term effects of these conditions on ureteral tissue are not fully understood.

Purpose of the Study:

  • To compare the microscopic features of distal ureters in children with recurrent UTIs and VUR to those without urinary tract disease.

Main Methods:

  • Microscopic examination of 37 distal ureteral resection specimens from children with recurrent UTIs/VUR.
  • Comparison with 51 postmortem distal ureter specimens from children without urinary tract disease.

Main Results:

  • Significant variation in fibrosis and inflammatory changes was observed in both study groups.
  • No discernible microscopic differences were found between the ureters of children with and without a history of UTIs and VUR.

Conclusions:

  • Microscopic analysis did not reveal distinct pathological changes in the distal ureters of children with recurrent UTIs and VUR compared to controls.
  • Further research may be needed to identify potential subtle or functional changes associated with these pediatric conditions.

Ureters01:22

Ureters

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...
The Micturition Reflex01:26

The Micturition Reflex

Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating urine...

Anatomy of the Genitourinary System I: Kidneys and Ureters

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...

Anatomy of the Genitourinary System II: Bladder and Urethra

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
