Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations01:26

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

679
Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...

Urinary Bladder01:23

Urinary Bladder

4.2K
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 I: Health History

570
The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...

Urinary Tract Calculi V: Nursing Management

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

Disorders of the Urinary System01:20

Disorders of the Urinary System

1.9K
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...

Urinary Tract Infection IV: Nursing Management01:17

Urinary Tract Infection IV: Nursing Management

595
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...

Summary
This summary is machine-generated.

Sudden whole-body cooling can cause urinary frequency. This is partly mediated by specific receptors in the body, with TRPM8 (transient receptor potential melastatin 8) channels potentially playing a role.

Area of Science:

  • Urology
  • Neuroscience
  • Physiology

Background:

  • Limited research exists on cold stress and urinary urgency.
  • Cold exposure can induce bladder overactivity via alpha-adrenergic receptors and specific nerve pathways.

Purpose of the Study:

  • To review the connection between cold stress and urinary frequency.
  • To explore the role of TRPM8 channels in cold-induced urinary symptoms.

Main Methods:

  • Review of previous studies on cold stress and urinary frequency.
  • Immunofluorescence staining to detect TRPM8 presence.
  • Experimental stimulation of TRPM8 to observe urinary effects.

Main Results:

  • Cold stress induces bladder overactivity in rats, partly through alpha1A-adrenergic receptor (AR) and alpha1D-AR.
  • TRPM8 channels are present in rat skin and their stimulation by menthol leads to urinary frequency.
  • Resiniferatoxin-sensitive nerves may also regulate bladder activity during cold stress.

Conclusions:

  • Cold stress triggers urinary frequency through complex mechanisms involving adrenergic receptors and potentially TRPM8.
  • TRPM8 channels, known for sensing cold and menthol, may be involved in the micturition control system.
  • Further research is required to fully elucidate the role of TRPM8 in cold-induced urinary frequency.
