title: Percutaneous needle biopsy of the transplanted kidney: technique and complications.
abstract: Over 11 1/2 years, 420 percutaneous needle biopsies were obtained from the transplanted kidneys of 205 patients at one institution. The procedure was performed by one nephrologist and 55 nephrology trainees. No limit was placed on the number of biopsies performed on one kidney, and the highest number was seven. The complications were macroscopic hematuria in 28 biopsies, prolonged hematuria (greater than 24 hours) in eight, transient anuria in five, and prolonged anuria requiring surgical intervention in one. Perinephric hematoma occurred in three patients; retroperitoneal hematoma led to compression of the iliac vein in one. None of these complications led to loss of the transplant. It is suggested that the freedom from serious complication is related to the safety of the technique and the precautions applied to preparation of the patient. These are described in detail.
