Imaging Studies VI: Voiding Cystourethrography and Cystography

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...

Nursing Assessment of the Genitourinary System II: Inspection and Palpation

Nursing Assessment of the Genitourinary System II: Inspection and Palpation

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease. Look for...

Assessment of the Abdomen III: Palpation

Assessment of the Abdomen III: Palpation

Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Imaging Studies II: Ultrasonography

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Vagina

Vagina

The vaginal canal is a tubular structure averaging about 10 cm in length that acts as the entryway to the female reproductive system and the passageway for menstrual flow and childbirth. The interior walls of the vagina exhibit concentric folds called rugae and are topped by an area known as the fornix, which connects with the protruding cervical portion of the uterus. This canal is comprised of an external fibrous layer, a muscular middle layer, and an inner lining with mucosal rugae, which...

Nursing Assessment of the Genitourinary System III: Percussion and Auscultation

Nursing Assessment of the Genitourinary System III: Percussion and Auscultation

The genitourinary system maintains the body's fluid balance, waste excretion, and overall homeostasis. Proper assessment is essential for early detection of disorders, with percussion and auscultation integral to this evaluation. These methods help identify signs of kidney or bladder issues and provide important diagnostic clues.Percussion for Kidney TendernessPercussion is used to assess tenderness and detect kidney and bladder abnormalities. A common method for determining kidney tenderness...

Area of Science:

Biomedical Engineering
Gynecology
Tissue Biomechanics

Background:

Pelvic organ prolapse (POP) affects over 50% of women, linked to changes in vaginal wall elasticity and connective tissues.
Understanding the biomechanical properties of pelvic support tissues is crucial for POP development and surgical repair.
Current methods for assessing tissue elasticity in POP are limited.

Purpose of the Study:

To evaluate the applicability of a novel vaginal tactile imager (VTI) for assessing pelvic floor tissue elasticity.
To analyze VTI's potential in characterizing normal and POP conditions.
To assess VTI's utility in evaluating the outcomes of reconstructive pelvic surgery.

Main Methods:

Design and prototyping of a vaginal tactile imager (VTI) for tactile imaging.
Pilot clinical study involving 13 patients undergoing reconstructive pelvic surgery.
Analysis of VTI data to assess vaginal wall rigidity and elastic properties.

Main Results:

VTI successfully visualized increased rigidity in vaginal walls post-reconstructive surgery with mesh grafts.
The study demonstrated VTI's capability to image variations in tissue elasticity.
Preliminary findings suggest VTI's potential for prolapse characterization and detection.

Conclusions:

Vaginal tactile imaging is a promising tool for evaluating reconstructive surgery outcomes in POP.
VTI has the potential to aid in the characterization and detection of pelvic organ prolapse.
Further research is warranted to fully establish VTI's clinical utility in women's health.
