A modified pyelo-ureteroplasty for congenital hydronephrosis due to long segment of ureter stenosis / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate a modified pyelo-u re teroplasty in treating long segment of ureteropelvic junction (UPJ) stenosis. Methods 26 cases were treated with the designed pyelo-ur eteroplasty,on which the dilated pelvic was incised vertically and the pelvic fl ap was turned down to form a new infundibulas tube with running suture and was a nastomosed to the ureter stem,the long stenosis segment being cut off. Results The symptoms vanished in the follow-up period of 1～3 ye ars.It was showed by B-ultrasonography,IVU and RP (retrograde pyelography)that the anastomosis site in all the cases was smooth.3～12 months after operation,G FR(glomerulus filtration rate) was found to be improved markedly,and 20 minutes excretive rate in the operated kidneys was all above 50%. Conclusio ns The troublesome hydronephrosis due to complicated long stenosis o f UPJ and upper ureter can be effectively treated by the modified pyelo-uretero plasty.
