Title: Complications caused by minimally invasive percutaneous nephrolithotomy under ultrasound guidance for upper ureteral calculus
Abstract: Objective To evaluate the complications caused by ultrasound-guided minimally invasive percutaneous nephrolithotomy(mPCNL) for the treatment of upper segment ureteral calculi,and preventive measures were explored.Methods Clinical data of patients who underwent ultrasound-guided mPCNL in our hospital from October 2008 to December 2012 were retrospectively analyzed.Of these cases,renal calculus were found in 428 cases,upper ureteral calculus in 267 cases,renal stones with upper ureteral stones in 135 cases.Diameter of stone was 1.5 ~ 3.2 cm,average diameter was 2.1 cm.Results The overall complication rate was 28.43%(236 cases),peel-away sheath placement failure occurred in 62 cases(7.47%),in which 2 cases needed the secondary surgery,the remaining 60 cases were treated by replacing the puncture point.Perforation of renal collecting system occurred in 150 cases(18.07%),which didn’t cause hemorrhage;21 cases required blood transfusion(2.53%),postoperative delayed hemorrhage occurred in 37 cases(4.46%),of which high sensitivity renal artery embolization in 3 cases(0.36%);pleural effusion occurred in 1 cases(0.12%),whom was cured after closed thoracic drainage for 5 days;162 cases with postoperative fever(19.50%) were healed after symptomatic treatment.No large vessel or viscera damage happened.Conclusion Ultrasound-guided minimally invasive percutaneous nephrolithotomy is effective to treat patients with renal calculus and upper ureteral stones.
