Objective:ToinvestigatetheDSAunderhighpressuresyringeinjectionmethodwithmanualbolusinjectionmethod arediscussedandanalyzedandcomparedinhysterosalpingography(HSG)anddiagnosticvalue,sothischeckHSGmoresecure, standardized,providingnewclinicaldiagnosisandtreatmentscientificbasis. Methods:Select infertility patients in our hospital HSG examination of 120 patients divided into two groups and the control group, the control group were treated with the artificial hand bolus injection, observation group pressure syringe injection of contrast compared tothesituation twogroups of patients.Tubal HSG weredivided into twogroupsofnormal and abnormal, normalfullyopen,abnormalitiesincludecompleteobstruction,passableandadhesionsaround.Completeobstructiontofurther distinguish the proximal and distal obstruction obstruction; Comparison of two methods of various differences between the situations. Results:Observation group were superior contrast ratio of 93.45%, significantly higher than 82.30%, the number of cases of adverse reaction, and patients in the observation group was significantly less than the control group, the difference was significant.
