ABSTRACT
Objective To evaluate the efficacy of solifenacin with or without tamsulosin in patients with overactive bladder (OAB).Methods Fifty-three patients with OAB were randomly divided into two groups (group A 27 patients, group B 26 patients).The patients received either solifenacin 5 mg/day in group A or combined with Tamsulosin 0.2 mg/day in group B for two weeks.During the treatent period all the patients recorded voiding and adverse events in a diary.The symptoms of urgency, frequency, incontinence were evaluated by OABSS scores at the begining and end of the therapy period.The results of the efficacy and safety were analyzed by using SPSS 13.0.Results The OABSS scores at the begining and end for the two groups were significantly different ( P ＜ 0.01 ).In both groups the efficacy was obvious.The OABSS scores at the end of the therapy between group A and B were significantly different (P ＜0.05 ).The efficacy of group B was better than that of group A.Conclusion The efficacy of solifenacin combined with tamsulosin was better than solifenacin alone in OAB.
ABSTRACT
Objective To evaluate and compare open and retroperitoneal laparoscopic adrenalectomy.Methods Clinical data of 30 cases undergoing open adrenalectomy and 119 cases undergoing retroperitoneal laparoscopic surgery were retrospectively analyzed. The 2 groups were compared in terms of these aspects: operation duration, intraoperative blood loss, postoperative analgesic use, time to remove drainage tube, time to resume eat, postoperative hospitalization time, complications, and tumor recurrence. In open surgery group, tumor diameter was between 0.5 cm -10.8 cm, 4.57 cm in average. 18 tumors were located on the left side and 12 tumors on the right side. In laparoscopic group, tumor diameter was between 0.8 cm -14.5 cm, 2.78 cm in average. 59tumors were located on the left side and 60 tumors on the right side. Patients in open surgery group were followed up for 6-72 months and retroperitoneal laparoscopic group 4-20 months. Results Open adrenalectomy were successful in all the 30 cases. 12 cases in laparoscopic surgery group converted to open surgery among whom 8 cases were due to poor visibility, 1 case due to renal artery injury, 1 case due to large tumor size, 1 case because of diaphragmatic injury and 1 case because of pleural injury. Laparoscopic surgery was superior to open surgery in terms of operation duration, intraoperative blood loss, postoperative analgesic use, time to start food taking, time to remove drainage tube, and postoperative hospitalization time. The difference had statistical significance (P ＜0.05 ). Conclusion Retroperitoneal laparoscopic adrenalectomy has advantages such as less trauma, less blood loss, and shorter recovery time, which make this procedure the modern golden standard for treatment of benign adrenal neoplasm.
ABSTRACT
Objective To discuss the reason of pain on the shoulders and epigastrium after the reprotenal laparoscopic operations. Methods One hundred and eight patients had undergone the laparoscopic adrenalectomy or laparoscopie renal cyst unroofing. They were divided into two groups at random, group A and group B. In group A, discharged CO2 as soon as finished the operation, but did not in group B. At the same period, there were 49 patients who had received retroperitoneal laparoscopic radical nephrectomy, divided into two groups by the CO2-pheunopertomeum time, group C and group D. In the group D, the CO2-pheunopertomeum time was over 90 minutes, and the time was less than 90 minutes in the group C. Evaluated the pain degree through the vision analogue score (VAS) and recorded the pH,PaO2, PaCO2,BE in the arterial blood in group A and B before and after operation. Results The incidence rate of pain postoperation was significantly higher in group B than A (P < 0.05). In group A and group B, there was no difference in PaCO2, PaO2, pH, BE in the arterial blood(P > 0.05 ). The incidence rate of pain and the grade of VSA both were significantly higher in group D than group C (P < 0.05). Conclusions The stimuli of acid materials such as carbonate that derived from postoperative residual CO2 is probably the main cause of the pain on the shoulders and epigastrium after the laparoscopicsurgery.
ABSTRACT
Objective To evaluate the clinical efficacy and complication rate by open or retroperitoneal laparoscopic radical nephrectomy for renal tumor with stages T1N0M0 or T2N0M0.Methods Between October 2003 and October 2006,90 patients with renal cell carcinoma,which were clinically localized stages T1N0M0 or T2NOM0 Based on the patients' options to undergo retroperitoneal laparoscopic radical nephrectomy (group A,49 patients)and open radical nephrectomy(group B,41 patients).The clinical efficacy were compared between group A and group B,retrospectively.Results In group A,the operations of 46 patients were successful,4 cases occurred major complications(8.7%)during the follow-up visit which lasted for (21.9±6.1)months.The operations in group B were all successful.9 cases occurred major complications (22.5%)during the follow-up visit which lasted for(24.9±7.8)months.All cases were renal malignant tumors with pathologically confirmed stages T1N0M0 or T2N0M0 and there were no renal pedical lymph node metastasis.The age,weight,body mass index(BMI),tumor size,operating time and the time of follow-up were no statistically significant differences between the two groups(P＞0.05),while the blood loss,amount of postoperative drainage,time to ambulation,recovery of intestinal function after operation,hospital stay,use of analgesic and transfusion blood or plasma in group A were significantly reduced than those in group B(P＜0.01). Conclusions As compared with open radical nephrectomy,retroperitoneal laparoscopic radical nephrectomy afords patients with renal cell carcinoma an impreved postoperative course with minimal invasion,less pain,quicker recovery and less complications,while providing equally effective cancer control for patients with T1N0M0 or T2N0M0 tumor.
ABSTRACT
Objective To investigate the effects of intravesical therapy with elemene in preventing postoperative recurrence of superficial bladder cancer and its toxic and side effects. Methods This series included 123 patients with superficial bladder cancer (T 1),consisting of transitional cell carcinoma GⅠ in 37 cases,GⅡ in 73 and GⅢ in 13.They all underwent surgical treatment. Postoperatively, they were randomly assigned to 2 groups:63 patients in elemene group received instillation of elemene (400 mg,once a week) 2 weeks after operation and 60 patients in mitomycin C (MMC) group received instillation of MMC(40 mg,once a week) 2 weeks after operation. The instillations were repeated for 6 weeks and thereafter monthly for 1 year.The recurrence rates,side effects,and NK cell activity before and after treatment were evaluated. Results The recurrence rate of elemene group (mean follow-up of 19.7 months) was 7.9% (5 cases),which was significantly lower than that (25.0%,15 cases) of MMC group (mean follow-up of 19.4 months;P
