Nursing Assessment of the Genitourinary System II: Inspection and Palpation01:26

Nursing Assessment of the Genitourinary System II: Inspection and Palpation

266
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...

Urinary Bladder01:23

Urinary Bladder

1.7K
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...

Nursing Assessment of the Genitourinary System III: Percussion and Auscultation

142
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...

Disorders of the Urinary System01:20

Disorders of the Urinary System

536
The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

Anatomy of the Genitourinary System II: Bladder and Urethra

246
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...

The Micturition Reflex01:26

The Micturition Reflex

1.2K
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

Area of Science:

  • Gerontology
  • Urology
  • Physiology

Background:

  • Impaired urinary bladder evacuation is common with aging, affecting both men and women.
  • Symptoms include storage, voiding, and post-micturition issues, potentially leading to urinary retention and reduced quality of life.
  • The exact causes of underactive detrusor are not fully understood, and diagnostic criteria are not standardized.

Observation:

  • Urodynamic study (UDS) is the current standard for diagnosing underactive detrusor, despite being invasive.
  • A 73-year-old male presented with urinary symptoms and abdominal distension, indicative of bladder dysfunction.
  • The case highlights the clinical challenges associated with diagnosing and managing impaired bladder emptying.

Findings:

  • Underactive detrusor, a condition affecting bladder emptying, lacks effective therapeutic options.
  • Current treatment goals focus on symptom improvement and complication risk reduction.
  • Further investigation is needed to understand the etiopathogenesis and develop better treatments.

Implications:

  • This condition significantly impacts patients' quality of life, necessitating improved diagnostic and therapeutic strategies.
  • The lack of effective treatments underscores the need for advancements in urological care for the aging population.
  • Developing non-invasive diagnostic methods and effective therapies for underactive detrusor is a critical unmet need.
