Imaging Studies VI: Voiding Cystourethrography and Cystography01:22

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: Uroflowmetry01:19

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 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...

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

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...
Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Area of Science:

  • Urology
  • Gynecology
  • Pelvic Floor Disorders

Background:

  • Postoperative voiding dysfunction is a significant complication following pelvic organ prolapse (POP) surgery.
  • Current prediction models often lack sufficient accuracy, necessitating improved risk stratification.

Purpose of the Study:

  • To evaluate the incremental predictive value of preoperative urodynamic parameters for postoperative voiding dysfunction after advanced POP surgery.
  • To compare the performance of prediction models incorporating clinical variables, uroflowmetry, and urodynamic parameters.

Main Methods:

  • Retrospective cohort study of 283 women undergoing advanced POP surgery.
  • Sequential multivariable logistic regression models were built using clinical data, uroflowmetry, and urodynamic parameters.
  • Model performance was assessed using discrimination (AUC), calibration, and decision-curve analysis.

Main Results:

  • Postoperative voiding dysfunction occurred in 19.8% of patients at 6 months.
  • Model discrimination improved progressively: clinical variables (AUC 0.68), plus uroflowmetry (AUC 0.72), plus urodynamics (AUC 0.78), and the combined model (AUC 0.82).
  • The multimodal model incorporating urodynamic parameters demonstrated superior predictive accuracy and clinical utility.

Conclusions:

  • Preoperative urodynamic parameters significantly enhance the prediction of postoperative voiding dysfunction in POP surgery patients.
  • A multimodal approach integrating clinical, functional, and physiological data provides the most accurate risk estimation.
  • This improved risk stratification supports individualized perioperative management strategies for POP surgery.
