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...

Acute Kidney Injury II: Pathophysiology

189
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Urinary Tract Calculi II: Pathophysiology and Clinical Manifestations

78
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...

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...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Acute Pyelonephritis I: Introduction

88
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

Summary
This summary is machine-generated.

Reflex anuria, a rare condition from kidney trauma, can cause acute kidney injury (AKI). This case highlights unilateral ureteric obstruction as a potential trigger, with bilateral nephrostomies proving effective.

Area of Science:

  • Nephrology
  • Urology

Background:

  • Reflex anuria is a rare condition characterized by temporary suppression of kidney function, often linked to trauma or irritation of one ureter or kidney.
  • It has been documented in cases of unilateral ureteric obstruction and following urological surgeries involving the ureters and bladder.

Observation:

  • A 33-year-old female presented with severe right loin to groin pain, progressing to oliguria.
  • Initial attempts at retrograde stent insertion were unsuccessful, necessitating bilateral nephrostomies.

Findings:

  • The patient's condition, characterized by oliguria, was attributed to reflex anuria, potentially triggered by an unidentified cause of unilateral ureteric obstruction.
  • Bilateral nephrostomies were successfully implemented as a treatment modality.

Implications:

  • Reflex anuria, though uncommon, warrants consideration in the differential diagnosis of acute kidney injury (AKI) after other causes are excluded.
  • Bilateral nephrostomies represent a viable therapeutic option for managing reflex anuria, particularly when less invasive methods fail.
