Percutaneous nephrostomy in the treatment of pyonephrosis. A comparative study apropos of 36 cases

This study is a comparison of the treatments used in 36 patients suffering from pyonephrosis. The patients were subdivided in two groups: cases having undergone previous percutaneous drainage; and cases having undergone primary nephrectomy. These latter cases presented a high complication rate. We believe that preliminary drainage by percutaneous nephrostomy, constitutes the procedure of choice, when ever possible, to drain the kidney and prepare the patient for nephrectomy.
