Urinary Tract Calculi VI: Surgical Management

35
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...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Extraction: Advanced Methods

541
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Area of Science:

  • Cardiovascular Interventions
  • Medical Device Extraction
  • Electrophysiology

Background:

  • Lead extraction is a critical procedure in managing cardiac implantable electronic device complications.
  • Conventional methods for lead extraction have limitations, especially in complex or chronic cases.
  • Limited data exists on the utility of shockwave intravascular lithotripsy (IVL) in lead extraction.

Observation:

  • Three challenging cases of pacemaker lead extraction were analyzed.
  • Initial attempts with conventional extraction methods were unsuccessful.
  • Shockwave intravascular lithotripsy (IVL) was employed as a pretreatment strategy.

Findings:

  • IVL pretreatment facilitated the extraction of complex and long-dwelling leads (up to 32 years).
  • The technique proved effective in cases where standard methods failed.
  • Successful lead extraction was achieved in all presented cases following IVL application.

Implications:

  • IVL may serve as a valuable adjunct tool for complex cardiac lead extractions.
  • This approach could expand treatment options for patients with challenging lead burdens.
  • Further research is warranted to establish the safety and efficacy of IVL in lead extraction.
