Abstract: ObjectiveTo analyze the clinical value of the visual puncture system for the treatment of lower calyx stones．MethodsEighteen patients with lower calyx stones admitted to our department from Agust 2016 to December 2016 were enrolled in this study. All the above 18 patients got percutaneous renal access successfully and received the holmium laser lithotrity. And the physical vibration lithecbole treatment a week later was undergone as well. Clearance rate of stones was observed 3 weeks after operation.ResultsPassages of 17 cases were dilated to 8F and then one-stage percutaneous nephrolithotomy was done. Passage of the other one case was dilated to 18F because of the concurrent infection with calyx carotid stenosis, and an 18F nephrostomy tube for drainage was retained， until the incision of renal calices and lithotomy was carried out 1 week later. One-stage lithotripsy was completed successfully in the 17 patients with no nephrostomy tube for drainage. The average operation time was 78.6 min．The mean estimated intraoperative blood loss was 29 ml． The mean postoperative hospital stay time of the patients was 5.6d． All the stones of the above cases disappeared 3 weeks after operation from the KUB review. Fever occurred in 2 patients after operation．No massive haemorrhage,pleural injury,intestinal injury or other complications occurred．ConclusionVisual puncture system in treatment of lower calyx stones has lower risk of bleeding, which is suitable especially for the management of renal stones in non-dilated collecting systems and is worth of popularization.
