Comparison of complications and analysis of factors affecting renal function decline after laparoscopic radical cystectomy with different urinary diversion methods / 中华老年医学杂志

Objective:To compare the complications associated with various urinary flow diversion methods and identify the factors that contribute to the decline in renal function after radical total cystectomy for myoinfiltrating urothelial carcinoma.Methods:This study conducted a retrospective analysis on the clinical data of 46 patients with pathologically confirmed muscle-invasive bladder cancer.The patients underwent laparoscopic radical cystectomy with either ileal conduit diversion(n=21)or ureterocutaneous diversion(n=25)between January 2017 and December 2021.Perioperative data, postoperative pathology, postoperative complications, and follow-up results were compared between the two groups.Results:The study found significant differences between the two groups in terms of age[(67±6)years vs.(73±8)years, t=3.132, P=0.003], Charlson comorbidity index adjusted for age[(3.80±1.15) vs.(4.52±1.03), t=2.223, P=0.031], prognostic nutritional index[(48.81±5.74) vs.(43.64±4.74), t=3.347, P=0.002], operation time[(449±108)minutes vs.(326±130)minutes, P=0.001]], hospital stay[(20.1±11.1)days vs.(13.3±5.2)days, t=2.762, P=0.008], proportion of Clavien grade 3 or higher complications within 3 months after surgery(4/21 vs 0/25, χ2=2.105, P<0.05), and proportion of stoma-free patients(18/21 vs.5/25, χ2=6.373, P<0.01). According to Logistic multivariate analysis, perioperative blood transfusion and urinary tract infection were identified as independent risk factors for renal function decline 12 months after surgery.Escherichia coli was found to be the most common bacteria cultured from urinary tract infections in both groups after surgery. Conclusions:Laparoscopic radical cystectomy with ureterocutaneous diversion offers benefits such as shorter hospital stays and fewer perioperative complications for older and frail patients.However, a higher proportion of patients may require ureteral stenting.It is important to note that perioperative blood transfusion and urinary tract infection are major risk factors for renal function decline following radical cystectomy.

Analysis of factors related to the efficacy of Tamsulosin monotherapy for overactive bladder symptoms in benign prostatic hyperplasia patients with the prostate volume <40 ml / 中华老年医学杂志

Objective:To assess the efficacy of Tamsulosin monotherapy for overactive bladder(OAB)symptoms in benign prostatic hyperplasia(BPH)patients with the prostate volume(PV)<40 ml, and to analyze related factors affecting the efficacy.Methods:300 BPH patients with OAB were enrolled, with an average age of(66.9±7.7)years and the PV<40 ml.Smoking, drinking and other living habits were investigated.Data on the Overactive Bladder Symptom Score(OABSS), International Prostate Symptom Score(IPSS)and Quality of Life Scale(QOLS)were collected before and after 4 weeks of treatment with Tamsulosin 0.2 mg QN.The maximum urine flow rate(Qmax)and bladder residual urine volume(PVR)were measured before and after treatment.OBASS was used as the main assessment parameter to analyze the correlation of efficacy with age, lifestyle, pre-treatment symptom scores, PV, Qmax and PVR.Results:257 patients completed the study, and 169 patients were treated effectively, with an overall effectiveness rate of 65.8%.The effectiveness rates of the mild, moderate and severe OAB groups were 83.6%, 62.4% and 38.5%, respectively, with statistical significance( χ2=13.037, P=0.001).3 patients showed adverse drug reactions, including 2 patients with mild dizziness and 1 patient with nausea.The baseline OABSS score, the proportion of smoking patients and the proportion of drinking patients in the effectively treated OAB group were significantly lower than those in the ineffectively treated group.Multivariate analysis showed that baseline OABSS score( OR=0.735, P<0.001)and smoking( OR=2.111, P=0.029)were correlated with tamsulosin's efficacy in treating BPH patients with OAB with PV<40 ml. Conclusions:The effectiveness rate of Tamsulosin for the treatment of BPH patients with mild OAB with PV<40 ml is high.The baseline OABSS score and smoking are factors affecting the efficacy of Tamsulosin on OAB symptoms in these patients.

Laparoscopic breast-conserving surgery combined with radiofrequency ablation to treat the early-stage breast cancer / 国际外科学杂志

Objective To analyze the clinical efficacy of the laparoscopic breast-conserving surgery combined with radiofrequency ablation to treat the early-stage breast cancer.Methods We collected 55 patients diagnosed early-stage breast cancer in retrospect,which started from January 2014 to December 2016.Twenty-seven of them were performed the laparoscopic breast-conserving surgery combined with radiofrequency ablation while others went through laparoscopic breast-conserving surgery without radiofrequency ablation.Meanwhile,we adopted the student t-test and the chi-square test to compare results of two groups.More specific,the main indexes of this study are including the post-operative local recurrence,the incidence of fat liquefaction or the incision-infection,operation time,post-operative hospital stay and the hospitalization expense.Results The laparoscopic breast-conserving surgery combined with radiofrequency ablation group had low local-recurrence than the laparoscopic breastconserving surgery group (0 and 7.69％).Additionally,there were no statistical differences between two groups in the incidence of fat liquefaction.However,The laparoscopic breast-conserving surgery combined with radiofrequency ablation group had more hospitalization expense than the laparoscopic breast-conserving surgery group [(4.1 ± 0.7) ten thousand yuan and (2.3 ± 0.6) ten thousand yuan,P ＜ 0.05].Conclusions Although the laparoscopic breast-conserving surgery combined with radiofrequency ablation group remarkably increased the hospitalization expense because of the utility of the radiofrequency ablation related apparatus,it may provide the probability of shaving more residual tumor cell and may low down the recurrence,especially not rising up the incidence of the post-operative fat liquefaction.Therefore,this surgery method might be one of the potential developments in the minimal-invasive of early stage breast cancer.

Practice of performance appraisal for directors of Shanghai public hospitals / 中华医院管理杂志

Objective To explore methods for performance appraisal of directors of municipal hospitals in Shanghai.Methods To assess the management performance of directors of 24 tertiary hospitals each year,measured by five dimensions of social satisfaction,management efficiency,capital operation,development sustainability and staff satisfaction,and 23 indexes.Results Implementation of the performance appraisal has witnessed constant improvement of patient satisfaction and quality of medical care,as well as rational control of medical expenses and cost.In 2014 for example,the cost of emergency/outpatients per visit at such hospitals were 312 yuan and 1 5 600 yuan per hospitalization respectively,with 7.6 days of stay in average.Also improved were service efficiency,clinical research output and hospital business performance in general.Conclusion Performance appraisal of directors of public hospitals proves an important means for guiding the hospitals to adhere to public welfare, consistent with the government medical institution operation target, and to strengthen internal management of such hospitals.

Intention survey of Shanghai medical workers with regard to reward for personal services / 中华医院管理杂志

Objective To find out about the intention of medical workers with regard to reward for personal services and explore the value of their labor. Methods An intention survey through questionnaires was conducted by means of random sampling among 1 424 medical workers from 6 hospitals in Shanghai with regard to reward for personal services and a model of expected income was obtained via multivariate stepwise regression analysis. Results Only 2.9% of the medical workers felt satisfied with their current total income. Such factors as professional titles, educational backgrounds, working years, and specialties all exerted some impact on the medical workers expected income. The expected income was several times that of the actual income, and there was a large difference between the expected incomes of people at different levels. Conclusion Reward to medical workers for personal services in China needs to be enhanced and reform of the distribution system should keep step with the reform of the personnel system.
