The Micturition Reflex01:26

The Micturition Reflex

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 urine...
Spinal Cord Injury ll: Pathophysiology01:14

Spinal Cord Injury ll: Pathophysiology

Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...
Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
Anatomy of the Genitourinary System II: Bladder and Urethra01:19

Anatomy of the Genitourinary System II: Bladder and Urethra

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...
Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations01:26

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

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

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...

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Urology

Background:

  • Sacral fractures, particularly Denis Zone III, can result in significant neurological deficits.
  • Neurogenic bladder dysfunction is a serious complication that requires prompt management.
  • Osteoporosis is an increasingly recognized risk factor for fragility fractures in the elderly.

Observation:

  • A 76-year-old male sustained a Denis Zone III sacral fracture with associated urinary retention and perineal numbness.
  • Computed tomography (CT) revealed a unique bilateral sacral lamina fracture pattern with displacement into the spinal canal.
  • The patient's sacrum showed signs of osteoporosis, suggesting a potential underlying fragility fracture.

Findings:

  • Surgical decompression via laminectomy effectively relieved pressure on the sacral nerve roots.
  • The patient experienced gradual but complete recovery of bladder function within three months post-surgery.
  • One-year follow-up demonstrated sustained neurological recovery and normal daily activities without urinary complaints.

Implications:

  • Laminectomy is a viable surgical option for managing Denis Zone III sacral fractures causing neurogenic bladder.
  • Early surgical intervention can lead to favorable outcomes and restoration of quality of life in patients with sacral fractures.
  • This case highlights the importance of considering osteoporosis in the etiology of sacral fractures in the elderly population.
