Summary
Spinning top urethra (STU) in children is linked to recurrent urinary tract infections (UTIs) and vesicoureteral reflux (VUR). This condition may stem from a neurogenic defect affecting bladder-sphincter coordination.
Area of Science:
- Pediatric Urology
- Urodynamics
- Child Health
Background:
- Dysfunctional voiding is a common pediatric urological issue.
- Spinning top urethra (STU) is a specific urethral morphology.
- The association between STU and dysfunctional voiding requires further investigation.
Purpose of the Study:
- To evaluate the role of spinning top urethra (STU) in children diagnosed with dysfunctional voiding.
- To compare clinical and urodynamic parameters between children with and without STU.
Main Methods:
- Retrospective review of 154 children (1995-2002) with dysfunctional voiding.
- Children categorized into Group I (STU) and Group II (normal urethral width).
- Comparison of gender, voiding symptoms, UTI, VUR, and urodynamic findings between groups.
Main Results:
- STU was more prevalent in girls (p=0.0316).
- Children with STU had higher rates of UTI (p=0.0154) and VUR (p=0.0018).
- STU group showed diminished bladder compliance (p=0.0335) and higher voiding pressure (p=0.0373).
Conclusions:
- Spinning top urethra (STU) is associated with recurrent UTIs, VUR, poor bladder compliance, and functional urinary obstruction in children.
- STU may result from a neurogenic maturation defect in detrusor-sphincter coordination.
- The findings suggest STU is an independent condition potentially linked to urofacial syndrome.

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...
01:19Urodynamic 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...
01:26The 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...

01:16Urethra
The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...

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...
01:23Urinary Bladder
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
