IntroductionPelvicrelaxationisacommonconditioninwhichthereisweaknessofthesupportingstructuresofthefemalepelvis,therebyallowingdescent(prolapse)ofoneormoreofthepelvicorgansthroughthe“potentialspace”of thevagina.Theseorgans include the following:urethra,bladder,rectum,smallintestine,uterus,andthevagina(vaginalvault)itself.Theurethraandbladderareanatomicallysituatedabovethe“roof”’ortopwallofthevagina,thecervixanduterusattheverydeepestpartofthevagina(theapex),andtherectumbelowthe“floor”orbottomwallofthevagina.Thus,whenprolapsedevelops,oneormoreofthefollowingmayoccur:theurethraandbladdermaydescendintothevaginalroof,thecervixanduterusmaydescendintothevaginalcanal,andtherectummayascendintothevaginalfloor.Pelvicrelaxationcanvaryfromminimaldescent—causingfew,ifany,symptoms—tomajordescent—inwhichoneormoreofthepelvicorgansliterallyprolapseoutsidethevaginaatalltimesandcausesignificantsymptoms.Thedegreeofdescentoftenvarieswithpositionandactivitylevel,increasingwith theassumptionof theuprightpositionandwithexertional activities, anddecreasingwith lyingdownand resting.
Pelvicrelaxationusuallyresultsfromacombinationoffactorsincludingmultiplepregnanciesandvaginaldeliveries(especiallydeliveriesoflargebabies),menopause,hysterectomy,aging,weightgain,andanyconditionassociatedwithchronicincreasesinabdominalpressure,suchasasthmaandbronchitis(chronicwheezingandcoughing),seasonalallergies(chronicsneezing),orconstipation(chronicstraining).Vaginalbirthisprobablythesinglemostimportantfactorinthedevelopmentofprolapse.Passageof the largehumanhead through the femalepelviscauses tissue trauma, separationorweaknessofconnectivetissueattachments,andalterationsinthegeometryofthepelvis.Itisunusualforwomenwhohavenothadchildrenorwhohavedeliveredbyelectivecaesariansectiontodevelopsignificantpelvicrelaxation.
Becausethefemalegenitaltractandurinarytractareintimatelyrelated(duetotheiranatomicproximityaswellasacommonembryologicalorigin),pelvic relaxationcancause significantchanges innormalurinary function.These range fromstressurinary incontinence(aspurt-likeleakageofurinefromtheurethraassociatedwithanincreaseinabdominalpressuresuchasoccurswithsneezing,coughing,etc.),to

Why a Urologist?You may wonder why a urologist is interested in female pelvicrelaxation,sinceformanyyearsurologywastraditionallyconsideredtobeamalefield.Inthelate1970’s,femaleurologyemergedasaspecialtybranchofurologymuchaspediatricurologyhaddonepreviously.ThepersonlargelyresponsibleforthisemergencewasDr.ShlomoRaz,directoroffemaleurologyattheU.C.L.A.SchoolofMedicine.Dr.Raz, aworld-renownedphysician and surgeon,developedthefieldoffemaleurologyintoacomprehensivesurgicaldiscipline.InadditiontowritingthetextbookAtlas of Transvaginal Surgery and editing the textbook Female Urology, Dr. Raz isresponsibleforredefiningthepreviouslyconfusingnomenclatureoffemalepelvicanatomy.Forthepastfourdecades,Dr.RazhashostedafellowshipatU.C.L.A.inwhichtwosurgeonsperyeararetrainedwithhiminallaspectsoffemaleurology.IwasfortunatetobeselectedforoneofthesepositionsandafterthecompletionofmyurologyresidencyattheUniversityofPennsylvaniaSchoolofMedicine,spenttheyears1987–1988operatingwithDr.Raz,focusingonprolapse,incontinence,andvoidingdysfunction.Obviously,prolapse isanexclusivelyfemalefield,butincontinenceandvoidingdysfunctionencompassbothfemalesandmales.Mypracticeis,infact,almostequallydividedbetweenwomenandmen,andIfindthatIenjoythisbalance.

For years, the urologist’s role infemalepelvicrelaxationwaslimitedtosurgeryforurinaryincontinence,andotheraspectsofpelvicrelaxationwere largely ignored. Similarly,the gynecologist’s role in femalepelvic relaxationwas focusedonprolapseofthebladder,uterus,andrectum,but ignored theurethralprolapse that isoften responsiblefor stress urinary incontinence.Thustherewasadivisionoflabor,a“territoriality”withintherealmoffemalepelvicsurgery,asillustratedinthiscartoondemonstratingtherolesoftheurologist,gynecologist,aswellasthecolon/rectalsurgeon.(Figure 1).Dr.Razespousedtheconceptofapelvicsurgeon,onecapableofdealingwithanyandallaspectsoffemalepelvicrelaxation,withathoroughknowledgeofpelvicanatomyandplasticsurgicalreconstructiveprinciples.TheultimategoalofthefemaleurologyfellowshipthatDr.RazestablishedbecametotrainaccomplishedpelvicsurgeonswhocouldthenobtainacademicpositionsatUniversitymedicalcentersthroughouttheUnitedStates,theappropriatevenueforfurtherdisseminationoftheartandscienceoffemaleurologyandpelvicreconstructivesurgerytomedicalstudentsandresidents in training.Thus,atHackensackUniversityMedicalCenter,oneofmyrolesistoinstructurologyresidentsandmedicalstudentsfromtheUniversityofMedicineandDentistryofNewJerseyintheprinciplesandsurgicaltechniquesofDr.Raz.
Femalepelvicreconstructivesurgeryincorporatesprinciplesofbothurological,gynecological,andplasticsurgery.Apelvicreconstructionforpelvicprolapseisnotdissimilartocosmeticfacialsurgicalproceduresperformedbyplasticsurgeonsforagingandsaggingeyelidsandjowels.Bothpelvic reconstructiveandplastic facial reconstructivesurgeryrequiresomedegreeofcreativityandartistictalentinadditiontotherequisite scientificknowledgeof anatomyandsurgicalprinciples.Ipersonallyfind female reconstructive surgery tobeparticularlygratifyingbecauseofboththeinstantabilitytoassesstheresultsbeforeleavingtheoperatingroomaswellasthegreatpotentialtoimprovethelifestyleandfunctionofthepersonsufferingwithprolapse.Unlikefacialcosmeticsurgery,pelvicreconstruction,inadditiontoimproving

Types of ProlapseURETHROCELE (urethralhypermobility)Greek“ourethra”=urethra&“kele”=hernia
Theurethra,thetubethatconveysurinefromthebladder,isabout11/2inchesinlengthandisfusedtothedistalthirdofthevagina.Descentof theurethra into theroofof thevaginaoccurswhen its supportstructuresbecomelax.Detachmentof theurethro-pelvic ligamentsfromthetendinousarcallowssuchdescent.Thiscausesstressurinaryincontinence,aspurt-like leakageofurinethatcanoccurwithanyactivitythatincreasesabdominalpressure,typicallysneezing,coughing,lifting,laughing,running,dancing,aerobics,etc.
