Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy01:26

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in critically...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
Continuous Renal Replacement Therapy01:30

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

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...
Imaging Studies VII: Vascular Imaging01:19

Imaging Studies VII: Vascular Imaging

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...

Area of Science:

  • Interventional Radiology
  • Nephrology
  • Urology

Background:

  • Surgical nephrectomy can be challenging for patients with recurrent kidney inflammation or bleeding.
  • Extensive surgery poses risks for patients in poor health.

Purpose of the Study:

  • To evaluate complete renal embolization as a safe and reliable alternative to surgical nephrectomy.
  • To assess the efficacy and safety of renal embolization in patients unsuitable for nephrectomy.

Main Methods:

  • Eight patients underwent complete renal embolization as a nephrectomy alternative.
  • Intravenous antibiotics and narcotic analgesics were administered.
  • Gentamicin instillation was used in patients with nephrostomy tubes before removal.

Main Results:

  • Indications included pain from hydronephrotic kidneys, bleeding from angiomyolipoma, post-resection bleeding, and spontaneous bleeding.
  • Successful embolization was achieved in all 8 patients.
  • Symptoms resolved in all cases at a mean follow-up of 30.6 months, with no long-term complications like hypertension, renal failure, or abscess.

Conclusions:

  • Complete renal embolization is a viable alternative to nephrectomy.
  • The procedure is safe, reliable, and minimally invasive.
  • It is well-tolerated with minimal long-term sequelae for patients with poorly functioning kidneys.
