This study was done to assess the safety and efficacy of real-time ultrasound-guided percutaneous renal biopsy (PRB) and to determine the optimal period of observation required as well as to ascertain the risk factors for any ensuing complications. Between 1 st February 2006 and 31 st January 2008, a total of 86 PRBs were performed by the radiologist using an automated biopsy gun with 16-gauge needle at the National Organ Transplant Centre, Central Hospital, Tripoli, Libya. Prior to the procedure coagulation profile was done in all the patients. All patients were kept on strict bed rest for 6-hours post-procedure. Of the 86 renal biopsies performed, 78 patients were referred from Rheumatology Department and 8 were post-kidney transplant recipients. There were 23 males with age ranging from 15 to 56 years and 63 females with age ranging from 16 to 66 years. A mean of 17.5 glomeruli were present in each specimen. A glomerular yield of less than five glomeruli was seen in only four biopsies. Class I lupus nephritis (LN) was seen in one patient, class II LN in seven patients, class III LN in 13 patients and class IV LN in 29 patients. All the eight renal allografts were diagnosed as either acute tubular necrosis or acute interstitial rejection. The overall complication rate was 5.8% and these complications were observed within 6 hours of biopsy. No late complications were seen. PRB under real-time ultra-sound guidance is a safe and efficacious procedure to establish the histological diagnosis of the renal disease and may be done as an out-patient procedure. A post-biopsy observation time of 6 hours appears to be optimal.
