Percutaneous renal biopsy and its findings in children and adolescents in saudi arabia: a single center experience.

A retrospective study of 108 consecutive renal biopsies in children and adolescents below 18 years of age performed at the King Fahd Hospital, Jeddah, during an eight-year period ending 1996, was made. All the biopsies were performed by a single consultant nephrologist and under ultrasound guidance. Tru-cut needles were employed in all cases and in the last two years, the bioptic gum was used. The age of the patients ranged between 3 months and 18 years with a mean of 10.6 years. There were 58 males and 50 females. All patients tolerated the biopsy well and there were no failures. The common side effects noted included gross hematuria in three (2.8%) and severe pain at the biopsy site in 11 (10.2%). None of the patients needed blood transfusions or prolonged hospitalization. Nephrotic syndrome was the commonest indication for performing the biopsy (83.3%) and among them, minimal change was the commonest lesion found (25%) followed by focal and segmental glomerulosclerosis (14.8%) and mesangial proliferative glomerulonephritis (15.7%). Our study further shows that renal biopsy is a safe procedure in children and the commonest indication is nephrotic syndrome.
