Interventional nephrology in Brazil: current and future status.
The care of chronic kidney disease patients frequently involves many diagnostic and interventional procedures. Most of these procedures are currently performed by radiologists, vascular surgeons, and general surgeons. This has caused fragmented medical care, which has led many nephrologists to introduce a new paradigm, often referred as interventional nephrology (IN). The aim of this study was to establish the extent of involvement of the Brazilian nephrology community with regard to specific IN procedures. From October 2004 to February 2005, questionnaires were sent by e-mail to all 2500 nephrologists throughout Brazil. The enrollment questionnaire was composed of five sections, with questions about renal biopsy, specific training in ultrasonography, peritoneal dialysis access (insertion of peritoneal catheters guided or not by peritoneoscopy), hemodialysis vascular access (ability to place tunneled catheters, construction of arteriovenous fistulas, and other vascular access procedures), and the nephrologist's interest in being trained in IN. A total of 239 nephrologists answered the questionnaire. Only 18% of Brazilian nephrologists perform kidney biopsy guided by ultrasonography assisted by a radiologist. On the other hand, 42% of them reported that this procedure was done without any image support. Most of the respondents (85%) indicated that they were not formally trained to perform renal ultrasonography. When asked about peritoneal dialysis catheter placement, 66% of the respondents reported that they referred their patients to a surgeon for this procedure. The insertion of peritoneal dialysis catheters guided by peritoneoscopy was reported by 3% of the respondents. Similar to the results for peritoneal dialysis catheter placement, the majority of the respondents (77%) indicated no training in the insertion of tunneled catheters for temporary hemodialysis. Regarding the interest of nephrologists to participate in an IN program, the great majority (87%) responded that they would like to be trained in these procedures. Most nephrologists are not trained in IN procedures. Therefore, in Brazil, it will be necessary to develop training centers for IN that will allow nephrologists to optimize nephrology care.
