Summary
Video urodynamics (VUDS) can provide valuable anatomical detail but involves radiation. This study found abnormal VUDS findings linked to diabetic cystopathy or urinary retention, suggesting judicious patient selection for this procedure.
Area of Science:
- Urology
- Diagnostic Imaging
- Lower Urinary Tract Dysfunction
Background:
- Urodynamics assesses lower urinary tract function.
- Video urodynamics (VUDS) integrates fluoroscopy for anatomical detail.
- Fluoroscopy in VUDS necessitates extra staff, equipment, and radiation safety protocols.
Purpose of the Study:
- To identify patient characteristics associated with abnormal fluoroscopy findings in VUDS.
- To enhance patient selection criteria for VUDS.
- To optimize the use of VUDS in clinical practice.
Main Methods:
- Retrospective chart review of women aged 18+ undergoing urodynamic studies (January 2022-September 2025).
- Data collected included demographics, medical history, fluoroscopy findings, neurogenic lower urinary tract dysfunction (NLUTD) evidence, and radiation exposure.
- Statistical analyses performed using R and JMP software.
Main Results:
- Of 223 patients, 33.6% exhibited abnormal bladder appearance on fluoroscopy.
- Abnormal findings correlated with older age, urinary retention, and higher radiation exposure.
- Normal findings were associated with mixed urinary incontinence (MUI) and early-stage multiple sclerosis; abnormal findings with diabetic cystopathy.
Conclusions:
- Abnormal VUDS findings are linked to diabetic cystopathy or urinary retention.
- Normal VUDS findings are associated with MUI or early-stage multiple sclerosis.
- Findings support judicious VUDS utilization based on individual patient profiles.

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...
01:22Imaging 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...
01:28Microbiota of the Urogenital Tract
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...
01:29Urine Studies I: Urinalysis
Urinalysis is a widely used diagnostic test that analyzes urine's physical, chemical, and microscopic characteristics. Healthcare providers use it to detect and monitor various health conditions, including renal disease, urinary tract infections (UTIs), diabetes, and metabolic or systemic disorders.Components of UrinalysisUrinalysis consists of three primary components: physical, chemical, and microscopic examination. Each provides unique insights into the urine sample and, by extension, the...
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.

01:28Urologic Endoscopic Procedure: Cystoscopic Examination
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...
