Objective To compare the results of single and repeated percutaneous sclerotherapy in patients with simple renal cysts .Methods 96 patients with simple renal cysts underwent needle aspiration and sclerotherapy under CT guidance. 45 patients (group A) underwent one session of sclerotherapy with 99.7% ethanol immediately after aspiration and 51 patients (group B) underwent repeated sclerotherapy at least twice. The patients were followed up using ultrasonography or CT at 3～6 months intervals. The complete or almost disappearance of the renal cyst was considered a successful treatment.Results The efficacy of treatment was significantly different in two group . The overall effective rate were 91.1% and 98.8% in group A and group B , respectively. The rate of complete regression was significantly better in group B (80.4%) than in group A (62.2%,?

Objective To explore the sen sation recovery of superficial palmar branc h of the radial artery flap with palmar branch of median nerve and donor si te. Methods From January, 2014 to June, 2016, 12 cases of finger soft tissue defects were repaired with sup erficial palmar branch of the radial artery flap with palmar branch of median nerve. The 2 g tactile sensation, 5 g pain sen sation, 30 g pressure sensation and static two-point discrimination (S2 -PD) of the flap was tested regularly. The S2 -PD of the palmar cutaneous branch of the median nerve were recorded respectively on the affected side and the unaffected side. The results were applied comparative t-test to perform statistical analysis, to observe the sensory recovery of the flap and donor site. Results The flaps survived.Twelve cases was followed-up for 6-18 mont hs. The pressure sensation of about 83.3％ of patients recovered after 2 months and 100％ of patients recovered after 3 months. The tactile sensation of about 91.7％ of patients recovered after 3 months and 100％ of patients recovered after 4 months. The pain sensation of about 91.7％ of patients recovered after 4 months of and 100％ of patients recovered after 5 months. S2-PD of the flap was the average of 8.3 mm in 6 months after operation. There were no significant differences in the S2-PD between the affected group [(12.08±2.15)mm] and unaffected group [(10.58±2.11)mm](P>0.05). And the sensory recovery of the control area of the palmar branch of the median nerve was S4 in 2 cases, S3+ in 9 cases, and S3 in 1 case. The sensory recovery was good. Conclusion Superficial palmar branch of the radial artery flap with palmar branch of median nerve can be used repair the skin defect of the fingers. The flap has a good sensery recovery, and the sensation of the donor area is gradually restored.
