title: [Antireflux procedures in advanced pyelonephritic kidneys. A modification of the grégoir-operation (author's transl)].
abstract: Kidneys in which pyelonephritic scars can already be observed radiologically are very sensitive to the dilatation, almost regularly following antireflux procedures: deterioration of renal function and progressing scarring may follow. - For these difficult cases a modification of the Grégoir Operation is proposed: 1 or 2 cm above the entrance of the ureter into the bladder wall the ureter is incised and a splint of small size introduced up to the renal pelvis. This splint is meant to remain as long as an uninhibited flow of urine through the operation site (the submucosal channel) can be consistently registered by image amplifier. - The described procedure has been executed in 12 cases without serious complications. In no case a postoperative dilatation of the upper urinary tract had to be registered. Further and longtime results will be reported.
