title: [Initial treatment of pyonephrosis using percutaneous nephrostomy. Value of the technique].
abstract: Until early in the eighties, the initial treatment of choice for pyonephrosis was by emergency surgical excision, which carried a high intraoperative and early postoperative morbidity and mortality. The introduction of percutaneous nephrostomy, a technique with a low complication rate that permits easy access in dilated excretory tracts and is highly effective, as shown by the clinical and analytical course of the patients with pyonephrotic kidney and by the number of nephrectomies performed, represented a substantial change in the initial therapeutic approach. The present article reports our experience of 123 percutaneous nephrostomies performed in 118 pyonephrotic kidneys over a period of 10 years, which constitutes one of the largest series reported in the literature. The clinical features and the findings disclosed by imaging techniques that permit making the diagnosis are presented. We describe the PCN procedure and its advantages, with special reference to the reduced morbidity and mortality, particularly in those cases complicated by septic shock. The procedure also permits evaluation of the underlying obstructive uropathy and function of the compromised kidney, therefore more renal units can be preserved, nephrectomy can be avoided and morbidity is minimal. For all the foregoing reasons, PCN guided by an imaging technique is currently the most effective initial treatment of pyonephrosis.
