Abstract
Objective： To evaluate the effectiveness and safety of ultrasound-guided balloon dilation in minimally invasive percutaneous nephrolithotomy（PCNL） for the treatment of renal calculi.Compared with metal and sequential fascial dilators,balloon dilators have certain advantages and are widely utilized in percutaneous nephrolithotomy.However,because balloon dilators are usually used under fluoroscopic guidance,they can be troublesome for urologists who are more accustomed to working under ultrasound guidance.Methods： Fifty patients with renal calculi were enrolled.These patients underwent ultrasound-guided percutaneous nephrolithotomy using balloon dilators.Preoperative and postoperative evaluations of calculi included color ultrasound,plain abdominal radiography,and intravenous urography.The intraoperative blood loss was evaluated by analyzing the decrease in hemoglobin compared with the baseline level.Manipulation speed was measured by tract establishment duration and operation duration.Results： These patients were matched in terms of age,gender,calculi location and burden.Tracts in all patients were successfully established in the first attempt and no rupture of the colon,pleura,or renal collection system occurred.Duration of cannulation were 13.66±1.42min（10~15min）,stone-free rate were 84.00%（42/50）,intraoperative blood loss were 5.49 ± 2.64g/L.Conclusion： Ultrasound-guided balloon dilation is feasible in minimally invasive percutaneous nephrolithotomy.It can ensure successful tractestablishment and operation duration,intraoperative blood loss and blood transfusion,and clearance of residual stone fragments.关键词
