Interventional nephrology

Interventional nephrology involves minimally invasive procedures used to diagnose and treat conditions related to the kidneys and their blood vessels. These procedures are typically performed by nephrologist using imaging guidance to ensure accuracy and safety.

One common procedure is the kidney biopsy, where a small piece of kidney tissue is collected using a thin needle, usually under ultrasound guidance. This helps nephrologist understand the cause of kidney problems, monitor existing diseases, or plan treatment. Patients may feel a brief pinch during needle insertion, but the procedure is quick and usually performed under local anesthetic.

Permcath placement involves inserting a special type of long-term dialysis catheter into a large vein, often in the chest. This is used for patients who need hemodialysis for an extended period but cannot have a traditional fistula or graft. The permcath allows for repeated access to the bloodstream with minimal discomfort and lower risk of infection compared to temporary catheters.

HD (hemodialysis) catheter placement is similar but typically for temporary use, such as in urgent situations where immediate dialysis is necessary. The catheter is usually placed in a neck or groin vein. Both permcath and HD catheter placements are done with careful imaging to minimize risks, and after the procedure, patients can usually return home the same day.
