Pyeloplastic surgery in the presence of suppurative pyelonephritis.

Six out of 135 pyeloplastic operations were performed in the presence of an acute infection. In spite of the inflammatory process the postoperative course was uneventful and the late results were also satisfactory. With the exception of one case, the operation was invariably of the Anderson-Hynes type, with splinting of the ureter and nephrostomy. The anastomosis was prepared with interrupted cat-gut stitches. Three cases are reported in some detail.
