在临床实践中,肾盂输尿管成形手术有很多问题值得提出探讨。1886年Trendenleburg作了第一例肾盂输尿管成型术,将狭窄的输尿管和扩张的肾盂作侧侧吻合。此后有关成型术的术式繁多,日本冈直友认为至今采用的成型术大致按照三种原则设计:(一) 肾盂Y形成型术(Foley氏法);(二) 肾盂部分切除和保留肾盂输尿管连 In clinical practice, there are many problems in the ureteropelvic surgery that are worth discussing. 1886 Trendenleburg made the first case of ureteropelvic polyneuroplasty, the narrow ureter and dilatation of the pelvis for lateral anastomosis. Since then, there are many surgical procedures for molding. According to three principles, Okamitsu believes that the molding methods used so far are designed according to three principles: (1) Foley’s Y-formation (Foley’s method); 2) Partial resection and retention of the renal pelvis and ureter even
