ObjectiveTo summarize the treatment of simple renal cysts experience,the advantages and disadvantages of the two surgical options. MethodsRetrospective analysis of 15 cases of renal cysts after general anesthesia in patients with laparoscopic cyst decompression in the clinical data and 21 cases of renal cysts underwent open surgery in patients with clinical data,comparative analysis of advantages and disadvantages of both types of surgery were conducted. ResultsIn this study,14 patients with laparoscopic surgery were successful,1 patient converted to open surgery,laparoscopic surgery in patients with blood loss,postoperative complications and time of staying hospital after operation postoperative hospital stay were significantly less than group of open surgery. ConclusionThe laparoscopic renal cyst decortication was a safe and effective treatment for simple renal cysts,compared to traditional open surgery in patients with trauma,less bleeding postoperative pain,rapid recovery,shorter hospital staying and so on.

Objective To investigate the ground glass appearance of solitary nodules of bronchioloalveolar carcinoma of the CT imaging features.Methods A retrospective analysis of 20 cases with pathologically proved with a ground glass appearance of solitary nodules of bronchioloalveolar carcinoma of the clinical and imaging data of CT.Results 20 cases of solitary nodules of bronchioloalveolar carcinoma without obvious clinical symptoms ;location:the upper lobe of the left lung in 10 cases,right upper lobectomy in 5 cases,3 cases of the right middle lobe,lower lobe of the left lung in 2 cases; all lesions were located at the lung periphery,both ground glass opacity nodules,14 of them patients with lesions of the peripheral see spiculation in 5 cases,vacuole sign,8 cases with air bronchogram,16 cases with pleural indentation,10 cases of vascular convergence sign etc..In 20 cases the lesion enhancement scan after the lesion showed no enhancement.In all cases,through the CT dynamic observation,no obvious change in lesion size,lesion slightly higher density,finally performed lobectomy pathologically diagnosed non mucoid alveolar cell carcinoma.Conclusion the ground glass appearance of solitary nodules of bronchioloalveolar carcinoma progress is slow,dynamic imaging observation helps to confirm the diagnosis.
