Analysis Of Risk Factors Of Postpartum Urinary Retention And The Effect Of Application Of Pelvic Floor Rehabilitation Techniques On The Postpartum Urinary Retention

Objective:Our study aim is retrospectively summarizing the high risk factors ofpostpartum urinary retention (PUR), analysising the occurrence and prognosis of thePUR,and exploring the treatment effect of the PUR after applying pelvic floorrehabilitation technology.Method:1.Randomly selecting393cases of the maternal vaginal delivery in theperiod from April2012to September2012. Among these,193human cases of maternalwho occurred postpartum urinary retention and given open-catheterization treatment iscase group.200case of maternal not occurred postpartum urinary retention is normalgroup. Collecting and sorting out two groups of clinical datas, doing univariate andmultivariate statistical analysis then.2. We are going to group the case group again,depending on the different methods of treatment.86cases of the case group treated witha low-frequency pulse electric is experimental group.100cases of them treated withconventional physical therapy is control group. Statisticsing situation about theincidence of refractory urinary retention，post-void residual volume, the number ofdays in hospital, hospitalization costs of the two groups and doing statistical analysis.Results:1.Univariate analysis showed that, the factors related to the occurrence ofurinary retention Include Painless childbirth(93%/82%,P=0.000),Midwiferyforceps(18%/1%,P=0.000), Vacuum extraction(6%/1.5%,P=0.015), Turning fetalhead(26%/12%,P=0.000), The first stage of labor time (527.85±207.70/482.53±217.26,P=0.035), Second stage of labor time (45.59±29.76/33.92±21.87,P=0.000). LogisticStepwise regression analysis showed that the independent risk factors for postpartumurinary retention contain Age （OR=1.105,P=0.020）,Painless childbirth（OR=2.540,P=0.009）,Midwifery forceps （OR=19.146,P=0.000）, Vacuumextraction （OR=5.190,P=0.013） and Turning fetal head （OR=2.154,P=0.011）. Descending order of OR of urinary retention is that: Midwifery forceps（OR=19.146）,Vacuum extraction （OR=5.190）, Painless childbirth（OR=2.540）,Turning fetal head（OR=2.154） and Age（OR=1.105）.2. Theresults of the experimental group after the withdrawal catheterization is that:Residualurine volume (P=0.001),The number of refractory urinary retention(P=0.002),Thenumber of days in hospital（P=0.006）,they are obviously less than that of the controlgroup.Conclusion: Painless childbirth, Midwifery forceps, Vacuum extraction, Turningfetal head, The first stage of labor, The second stage of labor time clearly increase therisk of postpartum urinary retention, And Age, Painless childbirth, Midwifery forceps,Vacuum extraction independent risk factors of PUR. Things of concern is that Turningfetal head is also the independent risk factors of occurrence of PUR. Low-frequencypulse electric therapy, which accelerating the bladder recovery, significantly reducingresidual urine volume and secondary catheterization rate, greatly reducing the time andcost of hospitalization,has a significant role in the treatment of PUR and is worthy ofclinical use.
