    ProlapsewithnosymptomsofincontinenceAdvancedPOP(pelvicorganprolapsequantitationsystem[POPQ]stageIItoIV)commonlycoexistswithSUI,however,formanywomentheSUImaybecomeapparentonlywhentheprolapsehasbeencorrected[1].ThisphenomenonisknownasoccultSUI.TestingforoccultSUIisdiscussedbelow(see'Detectingoccultincontinence'below).

    Anatomically,thisoccursbecauseinwomenwithsignificantanteriororapicalprolapse(usuallyprolapsepastthevaginalintroitus),thebladderneckisdisplacedposteriorlyandtheurethraiskinked,resultinginurethralobstruction.Theobstructionthenbecomesthemechanismofcontinence(figure1)[8].

    Themostcommonmethodsofprolapsereductionusethefollowingtoelevatethestructures:examiner'sfingers,largecottonswab,singlespeculumblade,ringforceps,orpessary.Whiletherearefewdatacomparingthesemethods,usingapessarymaybelesseffectiveatdetectingSUIthanothermethods[16,32].Thisislikelybecauseincontinencepessariesincreasethemaximumurethralclosurepressureandfunctionalurethrallengthand,thus,areoftenusedtotreatSUI[33].Somedatasuggestthatthebladdershouldbefilledtoatleast300mLinonestudy,occultSUIidentifiedwithuseofabladdervolumeof300mLwasmorelikelythan100mLtobeassociatedwithpostoperativeSUI[34].

    Inthelargeststudytoevaluateprolapsereductiontesting,dataregardingprolapsereductionusingfivemethods(manual,swab,speculum,forceps,pessary)werecollectedinwomenwithadvancedprolapse,butwithoutsymptomsofSUI(n=322)[16].ThesensitivityfordetectionofoccultSUIwassimilaramongmostreductiontestingmethods(17to39percent),withtheexceptionofthepessary,whichwaslesssensitive(5percent).Inourpractice,weuseoneortwolargecottonswabsbecauseitiswelltoleratedbypatientsandtheswabsarelongenoughtoapproximateasurgicalsuspensionofthevaginalapex.
