Abstract
The use of an automated biopsy device, and real-time ultrasound for percutaneous kidney biopsies (PKBs) has improved the likelihood of obtaining adequate tissue for diagnosis and also has reduced the complications associated with the procedure. We aimed to determine the frequency and type of complications associated with PKB and to determine the diagnostic yield. It was a retrospective file-based review of cases who underwent PKB of native kidney between January 2003 and December 2013 at the Aga Khan University Hospital in Karachi, Pakistan. PKBs were performed by trained nephrologists or radiologists using an automated device with a 16/18-gauge needle under real-time ultrasound. The data obtained included age, gender, clinical and histopathological diagnosis, and complications associated with the procedure (minor: hematuria, local infections, and hematoma; major: transfusions, severe infections, surgery, nephrectomy, arteriography, embolism, and death. Yield of the procedure was based on the number of glomeruli obtained. Patients having major complications were compared with the patients who had minor or no complications. A total of 433 native kidney biopsies were performed. The mean age of the patients was 41 ± 15.9 years, and 58% of the patients were male. The main histological findings were membranoproliferative glomerulonephritis (17.6%) followed by focal and segmental glomerulosclerosis (16.4%) and interstitial nephritis (13.9%). Majority of the procedures were performed by nephrologists (67.4%). The overall complication rate was 14.2%. Among those, 21 patients (4.8%) had a major complication while the others had minor complications. Of those who had a major complication, 17 patients required blood transfusion(s) and had hematuria or a major hematoma, three had prolonged hospitalization >24 hours, and one patient required surgical intervention. Only 10 procedures (2.3%) had inadequate tissue to establish the histopathologic diagnosis. PKB under real-time ultrasound guidance is a safe and efficacious procedure to establish the histological diagnosis of the renal disease.
