As an interventional nephrologist, you work with ultrasound technologies and perform various procedures in a hospital or clinic. Your responsibilities include inserting peritoneal and tunneled dialysis catheters to provide vascular access for hemodialysis patients. You also perform percutaneous endovascular procedures, ultrasound-guided renal biopsies, and ultrasonography of the kidneys. Interventional nephrology is fairly new to the medical industry, but the emergence of this new field has sped up the wait time for these procedures by creating a new type of specialist. Other duties include managing the dysfunction of arteriovenous fistulas and grafts for patients in end-stage renal disease.
