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...

Urodynamic 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...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

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...
Urinary Bladder01:23

Urinary 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...
Physiology of the Genitourinary System III: Urine Concentration and Dilution01:20

Physiology of the Genitourinary System III: Urine Concentration and Dilution

The kidneys concentrate or dilute urine to maintain water and electrolyte balance. Nephrons, particularly the loop of Henle, play a crucial role in this process through the countercurrent multiplication system. This system establishes a high osmolarity in the renal medulla, which is essential for water reabsorption. In the loop of Henle’s descending limb, water is reabsorbed into the surrounding medulla due to its permeability to water. In contrast, the ascending limb actively transports...

Summary

Female voiding dysfunction affects 12.8% of women with lower urinary tract symptoms (LUTS). Bladder outlet obstruction (BOO) is more common than detrusor underactivity, suggesting alpha blockers may help treat this condition.

Area of Science:

  • Urology
  • Female Lower Urinary Tract Symptoms
  • Voiding Dysfunction

Background:

  • Female voiding dysfunction lacks clear definitions and objective data.
  • Prevalence estimates vary widely, highlighting the need for standardized diagnostic criteria.
  • Complex etiologies contribute to the under-researched nature of this condition in women.

Purpose of the Study:

  • To investigate the characteristics and prevalence of female voiding dysfunction.
  • To establish diagnostic criteria and management strategies for female voiding dysfunction.
  • To differentiate between bladder outlet obstruction (BOO) and detrusor underactivity in women.

Main Methods:

  • A prospective, multi-center study involving 1,415 women visiting urology clinics.
  • Analysis of 792 patients with lower urinary tract symptoms (LUTS) using International Prostate Symptom Score (IPSS).
  • Objective data collection via uroflowmetry, residual urine volume, urinalysis, and pressure flow studies to define female voiding dysfunction (Q max ≤ 15 ml/s).

Main Results:

  • 12.8% of LUTS patients (102/792) reported voiding difficulty, with incomplete emptying and weak stream being most common.
  • 87.2% of these patients had bladder outlet obstruction (BOO), while 12.8% had detrusor underactivity.
  • Commonly observed concomitant conditions included overactive bladder and stress urinary incontinence.

Conclusions:

  • The prevalence of voiding difficulty in female urology patients with LUTS is 12.8%.
  • Functional bladder outlet obstruction (BOO) is more prevalent than detrusor underactivity in women with voiding difficulty.
  • Alpha blockers may be an effective treatment for female voiding difficulty attributed to functional BOO.
