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...

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...

Imaging 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...
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 Tract Calculi III: Medical Management01:30

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...
Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care01:30

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...

Summary
This summary is machine-generated.

Few urologists perform urinary diversion, with continent diversion more common among high-volume surgeons. Surgeon characteristics influence the type of urinary diversion a patient receives.

Area of Science:

  • Urology
  • Surgical Trends
  • Medical Practice Analysis

Background:

  • Urinary diversion is a critical surgical procedure for various urological conditions.
  • Understanding trends in its performance and the characteristics of surgeons performing it is essential for patient care.
  • Variations in surgical practice may influence patient outcomes.

Purpose of the Study:

  • To investigate the trends in urinary diversion utilization among urologists.
  • To identify surgeon characteristics associated with performing any urinary diversion.
  • To examine factors influencing the choice between incontinent and continent urinary diversion.

Main Methods:

  • Analysis of annualized case log data from the American Board of Urology (2002-2010).
  • Inclusion of urologists who certified or recertified during the study period.
  • Multivariate analysis to assess associations between surgeon demographics, practice type, and urinary diversion performance.

Main Results:

  • 37% of urologists performed urinary diversion, with a median of 4 cases annually.
  • Younger, female, oncologist-identified, and non-Northeast urologists were more likely to perform urinary diversion.
  • Continent urinary diversion was performed by only 9% of urologists, increasing with surgeon volume.

Conclusions:

  • A small proportion of urologists perform urinary diversion procedures.
  • High-volume surgeons are more likely to perform continent urinary diversion.
  • Patient choice of urinary diversion type may be influenced by surgeon characteristics and practice patterns.
