Objective To evaluate the clinical efficacy of retroperitoneal laparoscopic ureterolithotomy.Methods A total of 34 cases(38 sides) of middle(5 sides) or upper(33 sides) ureteral calculus were treated by retroperitoneal laparoscopic ureterolithotomy.The stones were(0.8 cm?1.0 cm)~(1.5 cm?3.0 cm) in size.Twenty cases had been previously treated by unsuccessful extracorporeal shock wave lithotripsy(ESWL).Results The operation was successfully completed in 33 cases and a conversion to open surgery was required in 1 case because of extensive adhesion and blood oozing.The operating time was 45~190 min(mean,85.5 min),the intraoperative blood loss was 10~50 ml(mean,20.6 ml),and the postoperative hospitalization,3~7 d(mean,4.3 d).Postoperative recovery was uneventful.No complication was observed during a 3~24 months(mean,9.7 months) of follow-up.Conclusions Retroperitoneal laparoscopic ureterolithotomy is micro-invasive,simple to perform,and safe.

BACKGROUND:With the development of microsurgical techniques, free flap transplantation has been widely used, which can solve the problem of insufficient local tissues.
OBJECTIVE:To observe the clinical effects of latissimus dorsi free flap transfer on the repair of al kinds of body surface defects, as wel as the role in complete tissue and functional reconstruction.
METHODS:From 2010 to 2013, 18 cases of various types of body surface defects were selected and using the microsurgical techniques, these complex wounds were repaired with free latissimus dorsi myocutaneous flaps. According to defect reason, primary wounds were treated for arteriovenous separation in the recipient zone. Most of the flaps were latissimus dorsi myocutaneous flaps at the affected side which were cut according to the wound size. If the cut muscle flap had a larger size and secondary wounds were difficult to be directly sutured, free skin grafts could be used to cover the residual secondary wounds.
RESULTS AND CONCLUSION:After transplantation, al the flaps survived with normal blood supply and wel-recovered function. Patients were more satisfied with the flap appearance. Latissimus dorsi myocutaneous flaps characterized as large donor area and secluded location have a great advantage in the repair of complex wounds using microsurgical techniques that can improve the survival rate of latissimus dorsi myocutaneous flaps.

Objective To investigate the safety and effectiveness of transurethral bipolar plasmakinefic resection in treating urethral stricture. Methods Totally 46 patients with urethral stricture were treated with transurethral bipolar plasmakinetic resection, and they were followed up for 3~12 months to observe the clinical effects. Results The segments of urethral scar were accurately incised and resected in all the 46 cases,24~26F bougies could pass through the urethra smoothly, and miction should be kept unobstructed. Totally 41 cases were followed up postoperatively, the maximal flow rate(Qmax) was ( 18.6±4.1 ) ml/s, which was obviously ameliorated as compared with that before operation(t=14.25, P<0.05);sexual function had no obvious changes before and after operation;no serious complications of urethral massive bleeding, urinary incontinence, fistula of urethral diverticulum,urethral perforation, rectal injury, etc. was observed. Conclusion Transurethral bipolar plasmakinetic resection is an effective method for treating urethral stricture, because it has fewer complications, faster postoperative recovery and lower recurrence.

BACKGROUND: It is still controversial that interspinous dynamic stabilization system Wallis and Coflex which one can provide better clinical effects for lumbar degenerative disease.OBJECTIVE: To systematically assess the clinical effectiveness and safety of Wallis and Coflex for lumbar degenerative disease.METHODS: According to the computer-based online search of PubMed, Embase, Medline, Cochrane Library, CBM,CNKI, Wanfang Database, and VIP, articles published before August 1st, 2016 were searched. Articles about Wallis comparing with Coflex for lumbar degenerative disease were included; the quality score of methodology was assessed by MINORS. Research data abstracted and synthesized by Review Manager 5.3 were used for meta-analysis.RESULTS AND CONCLUSION: (1) Six studies were included, and all studies were designed for non-randomized controlled trial. (2) There were no significant statistical differences in Japanese Orthopedic Association, Oswestry disability index, visual analogue scale score, Prolo functional score, segmental lordosis angle, and segment movement degree. Incidence of adverse events was significantlue scale less in the Wallis group than in the Conflex group (P < 0.05).(3) There was no significant difference in clinical efficacy between Wallis and Coflex in the early and mid-term follow-up.We can conclude that Wallis may provide better clinical safety than Coflex.

Objective To investigate the efficacy of twice irradiating with focused ultrasound on recurrent and metastasized U14 cervical cancer implanted in the legs of mice. Methods Seventy-two mice with U14 cervical cancer cells implanted in their legs were divided into three groups randomly,with 24 rats in each group.One group received a single dose of focused ultrasound,while mice in the second group were irradiated twice and surgery resection was administered to the third group 7 or 8 days after the tumor was implanted.After 23 days post implantation of the tumor,local tumor recurrence and metastasis to the lungs and lymph nodes were evaluated. Results The inhibition rate after double irradiation was 61.70% for local recurrence and 68.18% for metastasis,significantly higher than in the other two groups. Conclusions Both single and double irradiation with focused ultrasound are effective for inhibiting local recurrence and metastasis,but double irradiation is more effective.

Objective To analyze the endoscopic features of patients with the lower esophageal sphincter (LES) and crural diaphragm (CD) separation and explore its significance in hiatus hernia (HH) diagnosis.Methods From January 2011 to June 2012,the data of patients underwent esophagus high resolution manometry (HRM) examination were retrospectively analyzed and of which the patients with LES-CD separation were selected.Patients who received digestive tracts operation or lack of complete endoscopic date were excluded.A total of 93 cases were enrolled for analysis.According to Chicago Criteria,the cases were divided into three groups.There were 21 cases in type Ⅰ group (LES-CD separation<1 cm),37 cases in type Ⅱ group (LES-CD separation≥l cm and <2 cm),35 cases in type Ⅲ group (LES-CD separation≥2 cm).The differences among groups in endoscopic features were analyzed.HRM were taken as golden standard,the sensitivity and specificity of endoscopy in HH diagnosis were analyzed.Measurement data were expressed as x ± s,one-way ANOVA was performed for multi-groups comparisons,LSD method or Dunnett T3 test for pairwise comparisons and chi-square test or Fisher's exact test for two groups' comparisons.Results There were no significant differences in the distance between esophagus gastric junction (EGJ) and foreteeth of the three groups (P>0.05).Distances between EGJ and diaphragmatic HH pressure impression in type Ⅲ group,type Ⅱ group and type Ⅰ group were (3.57±0.78) cm,(1.89±0.81) cm and (1.14±0.67) cm,respectively and the differences were significant (LSDt=9.26,11.44,3.57; all P<0.05).The percentage of continuously-open cardia and showing pressure impression of the gastric pouch of type Ⅲ group was higher than that of type Ⅱ group and the percentage of continuously-open cardia and showing pressure impression of gastric poach of type Ⅱ group was higher than that of type Ⅰ group (80.0%,40.5% and 4.8%,x2 =11.64,29.76 and 8.59; 91.4%,27.0% and 4.8%,x2 =30.69,40.73 and 4.32' all P<0.05).The occurrence rates of the His angle blunting and sac of type Ⅲ group were higher than those of typeⅡ group and type Ⅰ group (74.3% and 77.1%,24.3% and 24.3%,4.8% and 4.8%,x2 =17.97 and 25.41,both P<0.05),there was no significant difference between type Ⅱ group and type Ⅰ group (P>0.05).The rates of esophagitis of type Ⅲ group and type Ⅱ group were higher than that of type Ⅰ group (71.4%,59.5% and 14.3%,x2 =17.14 and 11.15,both P<0.05),there was no significant difference between type Ⅲ group and type Ⅱ group (P>0.05).There was one case of Barrett's esophagus in each group.The sensitivity and specificity of endoscopy in HH diagnosis were 91.4% and 81.0%,respectively.Conclusions The distance between EGJ and hiatal pressure impression,continuously-open cardia,the His angle blunting,hiatal pressure impression of the gastric pouch and hernia sac were important indicators of HH endoscopic features.The sensitivity of endosocopy is higher than the spcificity of endosocopy in HH diagnosis.
