Acute Kidney Injury III: Clinical Manifestations01:29

Acute Kidney Injury III: Clinical Manifestations

331
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...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

102
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...

Imaging Studies VII: Vascular Imaging

100
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Acute Kidney Injury I: Introduction

197
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...

Summary

Renal infarction, a rare complication after lung surgery, can be indicated by elevated white blood cell count, lactate dehydrogenase, and C-reactive protein. Left upper lobectomy is a risk factor for this condition.

Area of Science:

  • Cardiovascular Medicine
  • Pulmonary Medicine
  • Nephrology

Background:

  • Renal infarction is a rare but serious complication following pulmonary resection surgery.
  • Early identification and management are crucial for mitigating severe morbidity associated with this condition.

Purpose of the Study:

  • To report a case of renal infarction following left upper lobectomy (LUL) and mediastinal lymph node dissection.
  • To highlight diagnostic indicators and potential risk factors for renal infarction post-pulmonary resection.

Main Methods:

  • A case study of an 80-year-old woman who underwent LUL for lung adenocarcinoma.
  • Monitoring of laboratory data including white blood cell count (WBC), lactate dehydrogenase (LDH), and C-reactive protein (CRP).
  • Diagnostic imaging using contrast-enhanced computed tomography (CT) and therapeutic intervention with heparin.

Main Results:

  • The patient presented with elevated WBC, LDH, and CRP on postoperative day 5, despite absence of typical symptoms.
  • CT scan revealed partial right renal infarction without signs of infection or pulmonary vein stump thrombosis.
  • Heparin therapy led to normalization of laboratory markers and resolution of the condition, with no recurrence of thrombosis.

Conclusions:

  • Left upper lobectomy (LUL) may be a risk factor for renal infarction.
  • Elevated WBC, LDH, and CRP levels serve as valuable diagnostic indicators for renal infarction post-pulmonary resection.
  • Prompt diagnosis and management, including anticoagulation, can lead to favorable outcomes.
