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...

Urologic 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...

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...

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.

Urinary Tract Infection IV: Nursing Management01:17

Urinary Tract Infection IV: Nursing Management

In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs like...

Area of Science:

  • Urology
  • Physiotherapy
  • Medical Device Development

Background:

  • Urinary retention affects men with incomplete bladder emptying or large diverticula.
  • Current methods may involve invasive procedures or carry risks of infection.
  • Neo-bladder patients and those with poor detrusor function may also benefit from improved bladder management.

Purpose of the Study:

  • To develop a simple, rapid, non-invasive, and non-catheter method for urine drainage.
  • To achieve bladder emptying without introducing infection.
  • To provide a cost-effective solution for managing urinary retention.

Main Methods:

  • The method is based on postural drainage principles from physiotherapy.
  • Involves kneeling with the torso horizontal, facing downwards, supported by a stool.
  • Utilizes graded pressure application for passive, low-pressure voiding, with a final stage using a crescent-shaped device.

Main Results:

  • Achieved an average of 43 mL in residual bladder volumes.
  • Demonstrated successful application over four years in a single patient case.
  • No complications, infections, or adverse effects were reported during the study period.

Conclusions:

  • The developed non-invasive method is effective for draining urine.
  • It offers a safe alternative to catheterization, preventing infection.
  • The technique shows promise for patients with chronic retention and potentially other bladder dysfunction conditions.
