Normal position of the ureteral orifice in infancy and childhood: a quantitative study
The Journal of Urology
|May 1, 1979
Insights
This study provides normal reference values for the distance between the vesicoureteral orifice and internal urethral orifice in children. These findings aid in diagnosing vesicoureteral reflux and related urinary tract conditions.
Area of Science:
- Pediatric Urology
- Anatomy
- Diagnostic Imaging
Background:
- The vesicoureteral orifice (VUO) to internal urethral orifice (IUO) distance is a critical anatomical parameter.
- Variations in this distance can indicate potential urinary tract abnormalities in children.
Purpose of the Study:
- To establish normative data for the VUO-IUO distance in infants and children.
- To correlate these measurements with various anthropometric parameters.
Main Methods:
- Retrospective analysis of anatomical measurements in a pediatric cohort.
- Data collection included age, height, weight, crown-rump length, and surface area.
- Standardized measurement techniques for VUO-IUO distance were employed.
Main Results:
- Normal ranges for the VUO-IUO distance were determined across different pediatric age groups.
- The study identified correlations between VUO-IUO distance and anthropometric factors.
- Approximate mean values were calculated for practical clinical estimation.
Conclusions:
- The established normal values serve as a crucial reference for pediatric urologists.
- Accurate VUO-IUO distance assessment aids in the diagnosis of vesicoureteral reflux.
- This data supports improved diagnostic accuracy and patient management in pediatric urology.
Abstract:
Normal values for the distance between the vesicoureteral orifice and the internal urethral orifice are given for different ages, heights, weights, crown-to-rump lengths and surface areas of infants and children. A simple estimate of approximate mean values for these measurements also is included.

01:22Ureters
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...
01:11Anatomy 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...
01:19Anatomy 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...
01:22Imaging 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. Intravenous Urography (IVU)Intravenous...
01:22Imaging 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...
01:19Urodynamic Studies: Uroflowmetry
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...
