Acute Kidney Injury II: Pathophysiology01:29

Acute Kidney Injury II: Pathophysiology

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...

Acute Kidney Injury I: Introduction

Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

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: Introduction01:27

Acute Pyelonephritis I: Introduction

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 as Proteus,...

Acute Kidney Injury III: Clinical Manifestations

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
Kidney Transplant II: Surgical Procedure01:26

Kidney Transplant II: Surgical Procedure

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Area of Science:

  • Nephrology
  • Obstetrics & Gynecology

Background:

  • Bilateral renal cortical necrosis (BRCN) is a rare complication following elective abortion, particularly in developed nations.
  • Acute renal failure following abortion necessitates prompt and accurate diagnosis to guide treatment.

Observation:

  • A case of anuric acute renal failure post-elective abortion is presented.
  • Initial diagnostics suggested thrombotic thrombocytopenic purpura/hemolytic uremic syndrome, but MRI indicated BRCN.
  • The patient was treated for septic abortion, receiving antibiotics and hemodialysis.

Findings:

  • Magnetic resonance imaging (MRI) proved essential in diagnosing BRCN, differentiating it from other thrombotic microangiopathies.
  • Early diagnosis of BRCN is critical for determining appropriate treatment strategies and predicting prognosis.
  • The patient achieved partial renal recovery with timely intervention.

Implications:

  • This case highlights the importance of considering BRCN in patients with anuric acute renal failure after abortion.
  • Urgent MRI evaluation is recommended for suspected BRCN to facilitate timely and effective management.
  • Improved diagnostic approaches for BRCN can enhance patient outcomes and renal recovery.
