title: [The role of percutaneous renal biopsy in kidney transplant].
abstract: Percutaneous renal biopsy (PRB) is an useful tool for diagnostic and therapeutic orientation in renal transplantation. PURPOSE--To evaluate the current role of PRB in post-transplant acute renal dysfunction (ARD) of renal allografts. METHODS--Sixty-five renal transplant patients were submitted to 95 valid renal biopsies with no major complications. RESULTS--There was disagreement between the clinical and the pathological diagnosis in 28 occasions (29.5%). In 36 cases (37.9%) the results of the pathological examination led to a modification in patient's management. These modifications were most commonly the avoidance or witholding of a steroid pulse (8 cases); nephrectomy of the renal allograft (8 cases); witholding or decrease of cyclosporine dosage (6 cases); giving a steroid pulse (5 cases) and giving antibiotics to treat acute pyelonephritis in 4 cases. The use of kidneys from cadaveric donors was significantly associated with an increased number of biopsies (p < 0.05). CONCLUSION--These results demonstrate that even though several less invasive procedures are currently employed, renal biopsy is still an indispensable method to the management of ARD in renal transplant patients.
