Disorders of the Urinary System01:20

Disorders of the Urinary System

172
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...

Physiology of Urine Formation01:24

Physiology of Urine Formation

2.1K
Urine formation is an essential function of the human body. It plays a critical role in maintaining homeostasis by regulating the volume and composition of body fluids. The kidneys, the primary organs involved in this process, filter blood to remove waste products and excess substances, ultimately producing urine.
Glomerular Filtration
The first stage in urine formation is glomerular filtration. Each kidney contains approximately 1 million nephrons, the functional units of filtration, with a...

The Micturition Reflex01:26

The Micturition Reflex

268
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...

Urinary Bladder01:23

Urinary Bladder

222
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...

The Parathyroid Glands00:59

The Parathyroid Glands

1.8K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Summary

Postoperative hypoparathyroidism (HP) after head and neck surgery is linked to bladder dysfunction. Patients with HP show increased lower urinary tract symptoms and higher post-voiding residue, indicating a need for monitoring.

Area of Science:

  • Urology
  • Endocrinology
  • Nephrology

Background:

  • Hypoparathyroidism (HP) following head and neck surgery can cause hypocalcemia and associated health issues.
  • Bladder function disturbances are a potential, yet understudied, comorbidity in these patients.

Purpose of the Study:

  • To assess lower urinary tract (UT) function in premenopausal women with postoperative HP.
  • To compare bladder function metrics between HP patients and healthy controls.

Main Methods:

  • Uroflowmetry was used to measure urine flow rate.
  • Validated questionnaires, including Overactive Bladder-Validated 8 (OAB-V8) and Interstitial Cystitis Symptom Index/Interstitial Cystitis Problem Index (ICSI/ICPI), assessed lower UT symptoms.
  • Post-voiding residue (PVR) was measured in both the hypoparathyroidism and control groups.

Main Results:

  • Patients with postoperative HP reported significantly higher ICSI, ICPI, and OAB-V8 scores compared to controls.
  • Higher post-voiding residue (PVR) levels were observed in the postoperative HP group.
  • Negative correlations were found between urinary symptom scores (ICSI, ICPI, OAB-V8), PVR, and serum calcium/parathyroid hormone (PTH) levels.

Conclusions:

  • Postoperative hypoparathyroidism is associated with significant lower urinary tract dysfunction.
  • Bladder dysfunction and related symptoms should be considered in the management of patients with postoperative HP.
