| Part Ⅰ Visualization analysis the current status the papers ofdiadnosis of bladder neck obstructionObjective To analysis the current status the papers of diadnosis of bladder neck obstruction.It can provide reference for the diagnosis of bladder neck obstruction in the futureMethods Computer retrieved was conducted to search Chinese Biomedical Literature Database,Chinese scientific and technical journals,China Academic Journal database,Pub Med and EMBASE.com.Our study extracted the information of author by BICOMS 2 software,at the same time,the figure of network of author was prepared by Net Draw and g CLUTO.Results There was a serious imbalance in the number of the distribution of authors,journal and province.Which were divided six research teams,although more and more researcher focused on the network meta-analysis,there must be relationships among different researchers and research institutions.at the same time,there were four reaearch topic in Chinese papers.at the same time there was a serious imbalance in the number of the distribution of authors,journal and countries.Which were divided three research teams,meanwhile,there were four reaearch topic in foreign papers.Conclusions Bladder neck obstruction diagnosis research in the world are less number of participating in many of authors,core authors,research institutions and journals are widely distributed.in the future,we should focuse mora research topic.Part Ⅱ Meta-analysis of accuracy of ultrasound for femalebladder neck obstructionObjective To assess the value of ultrasound for female bladder neck obstruction by meta analysis.Methods Computer retrieved was conducted to search Chinese Biomedical Literature Database,Chinese scientific and technical journals,China Academic Journal database,Pub Med and EMBASE.com,the studies of accuracy of ultrasound for female bladder neck obstruction were included,Meta Disc software was used to analysis data.Results Eight studies were included.The results show that the diagnosis odds ratio,sensitivity,specificity,positive likelihood ratio,negative likelihood ratio and SROC curve were 656.87(95%CI: 35.01-12325.72)、0.94(95%CI: 0.91,0.96)、0.95(95%CI: 0.92-0.97)、17.38(95%CI: 2.60-116.28)、0.03(95%CI: 0.00-0.47)and 0.9935,respectively.Conclusions The current evidence showed that ultrasound has high sensitivity and specificity for female bladder neck obstruction,Convenient and non-invasive,which may be benefit for bladder neck obstruction.Part Ⅲ The value of abdominal and transvaginal ultrasound fordiagnosis of female bladder neck obstructionObjective To investigate the sensitivity of the abdominal and transvaginal ultrasound in the diagnosis of female bladder neck obstruction.Methods 45 cases of female patients in the outpatient department of Gansu maternal and child health care hospital as the research object,female prostate disease patients in two states of adequate bladder filling and voiding,respectively transabdominal and transvaginal ultrasound scan to check the bladder neck,measuring the anterior and posterior lip thickness,and measurement of residual urine volume,according to residual urine volume were divided in two groups,the residual urine volume is less than or equal to 12 ml into group A,residual urine volume,13-49 ml for group B,residual urine amount is more than or equal to 50 ml for group C.Results There was no significant difference in the diagnosis of A and C(P>0.05),and the sensitivity of for the patients with B was significantly higher than that of the abdominal examination(P<0.05).Conclusions In the early stage of female bladder neck obstruction,the diagnosis of transvaginal ultrasound is superior to the diagnosis of abdominal ultrasound.It can quickly diagnose the obstruction of urinary tract caused by middle aged and old women,and can judge the extent of the disease. |
