[Results of the Anderson-Hynes kidney/calix plasty in 102 ureteral efferent stenoses]

Abstract

In 102 patients with ectasia of the renal calyx from degree I to III a pyelograft after Anderson-Hynes was performed. The leading clinical symptoms were, arranged according to frequency: flank pain, recurrent infections of the urinary tract, macrohaematurias, diffuse abdominal pain, palpable flank tumours. In general the diagnosis was made on the basis of the infusion urogramme; a retrograde pyelography was indicated only in cases of missing or insufficient excretion of the contrast remedy. According to the results of the operation apart from the Anderson-Hynes-graft in a lower pole vessel compressing the ureteral passage a ventral deposition of the anastomosis or resection of the lower pole vessel with or without simultaneous resection of the pole was performed. The results of the Anderson-Hynes pyelograft correlated with the degree of the preoperative ectasia of the renal calyx; with increasing degree of severity the good results decreased from 90% to 38%, whereas the bad results increased from 3% to 46%. Judging the success of the operation, a good correspondence between the clinical and radiological parameters was revealed in the degrees I and II. In degree III the numbers of cases were too slight, to secure a diverging tendency of these criteria.
