ABSTRACT

ObjectiveTo analyze the technique and clinical effect of percutaneous nephrolithotomy combined with endoscopic balloon dilation in the treatment of upper ureterostenosis with recurrent renal calculi. MethodsFrom June 2008 to June 2011,18 ureteral stenosis patients with the history of ureteral open surgery,postoperative residual or recurrent kidney stones were treated.There were 8 males and 10 females with the age of 27 -48 years.Fourteen cases were with hydronephrosis of 2 -4 cm,3 cases were with hydronephrosis of 5 -6 cm and 1 case was with hydronephrosis ＞6 cm.Subsequent stone size ＜ 1 cm was found in 15 cases,1 -3 cm in 3 cases,＞3 cm in 1 case.All patients were treated with percutaneous nephrolithotomy ultrasonic lithotripsy combined with balloon dilatation.The stone clearance rate,hydronephrosis changes,complications and IVP situation before and after surgery were analyzed.ResultsAll the 18 cases were completed surgery successfully.There was 1 (6％) case with renal hemorrhage 3 days after the surgery and controlled with DSA hemostasis.There was 1 case accepted adjusting double-J tube by ureteroscopy.Sixteen (89％) patient's stones were completed removed.One case with residual calyceal stones size ＜5 mm was not further treated.There was 1 case treated with nephrectomy because of renal stone with infection.The patients were followed up for 6 to 36 months.Fourteen cases with hydmnephrosis improved significantly; 3 cases with no significant changes but improved following balloon dilation.All patients achieved significant improvement in imaging study comparing of preoperative and postoperative data.ConclusionThe use of percutaneous nephrolithotomy combined with endoscopic balloon dilation is a safe and efffective treatment option in the treatment of kidney stones with ureteral stenosis.
