ABSTRACT
Objective To compare the efficacy of laparoscopy versus traditional surgery for elderly patients undergoing nephrectomy.Methods Totally 134 elderly patients undergoing nephrectomy diagnosed by CT or PET-CT were divided into the laparoscopy group and the traditional surgery group (n=67,each).Clinical symptoms,operation time,bleeding volume,analgesic use,the duration of drainage,exhaust time,length of hospital stay,adverse reactions and death rate were recorded.All patients were followed-up for 2 years.Results There were significant differences in the bleeding volume,operation time,analgesic use,duration of drainage and exhaust time between the laparoscopy group and the traditional surgery group [(141.2 ± 23.3) ml vs.(175.7 ± 31.7) ml,(162.4±13.1) min vs.(177.6±13.1) min,(60.7±15.1) mgvs.(89.2±17.7) mg,(2.4±0.9) d vs.(4.0±1.1) d,t=2.92,5.21,15.94,10.5,respectively,all P＜0.05].The incidence of postoperation complications was lower in the laparoscopy group than in the traditional group [4 cases (6.0％) vs.15 cases (22.4％),x2=11.03,P=0.001].Tumor relapse was found in 2 cases in the laparoscopy group and 3 patients in the traditional group.1 patient died in laparoscopy group and 2 patients in traditional group,respectively.There were no significant differences in tumor relapse and death rate between groups (both P＞ 0.05).Conclusions Laparoscopy is safe and effective for elderly patients undergoing nephrectomy and it can reduce the complications and adverse reactions,which can be the first choice for elderly patients undergoing nephrectomy.
ABSTRACT
Objective To investigate the effects of previous open nephrolithotomy on the technical features, outcomes and morbidities of subsequent percutaneous nephrolithotomy (PCNL). Methods Ninety-eight patients who underwent PCNL from January 2006 to January 2011 were selected in this study. The 34 patients of them who had previous open nephrolithotomy on the same kidney were assigned as group A, and the other 64 patients who had no previous open surgery as group B. The data of operation time, blood transfusion quantity, residual stones rate, hospitalization time and time of tube evulsion were collected and compared between the two groups. Results There were no significant differences between the group A and B with respect to the mean operative time [(84.0±24.6) min vs. (94.0±22.7) min, t=1.372, P=0.177], hospitalization time [(6.5±1.1)days vs. (6.3±1.8)days, t=0.49, P=0.261], blood transfusion quantity [(82.9±10.6) ml vs. (85.0±11.8) ml, t=0.415, P=0.682], kidney and colostomy channels [single channel(70.6% vs. 75.0%), double channel (29.4% vs. 25.0%), χ2 =0.22, P=0.638] and residual stones rate (5% vs. 3%,χ2=0.42, P=0.282). Conclusions When PCNL is performed after previous open nephrolithotomy, there is no difference in success rate and morbidities.
ABSTRACT
Objective To investigate the clinical value of laparoscopic hysteromyomectomy.Methods The clinical data of 98 cases of laparoscopic hysteromyomectomy(LM)and 76 cases of transabdominal Myomectomy(TAM)were retrospectively analyzed and comparison was made on the operative time,operative blood loss,postoperative blind enema time,body temperature recovery time,the rate of postoperative complicating disease and hospitalization after operation.Result Though the mean opertative time is the same,the mean operative blood loss,the mean body temperature recovery time,postoperative blind enema time,and the mean hospitalization was smaller in LM group than in TAM group(P＜0.05).Conclusion Laparoscopic hysteromyomectomy has the advantage of minimal invasion,short in-hospital days,fast recovery and low complication rate,which is an ideal treatment of hysteromyoma.
ABSTRACT
Objective To study the effect of-1 site single nucleotide polymorphism(SNP) on CCNH gene promoter transcription activity.Methods PCR and site-directed mutagenesis technology were used to construct CCNH basic promoter and-1G mutate promoter.Dual-Luciferase Reporter assay system was used to detect the transcription activity of constructed promoter.Results In AD293 cells,the activity of-1G mutate type promoter was significantly lower than that of wild type-1T promoter(P
