Umsele womlomo wesibeletho uyingxenye yomlomo wesibeletho, ukuxhuma ubulili kanye nesigqila sesisu. Ibukeka njengebhodi elincane noma i-pharynx. Umsele womlomo wesibeletho uhlanganiswe ne-mucosa, amangqamuzana ayo enza ipulagi eqinile ngesikhathi sokukhulelwa, okuvikela i-placenta ne-fetus kusukela ekungeneni kwezifo ezehlukene.
Umsebenzi walo uwukuthi:
- ukwabiwa kwegazi ngesikhathi sokuya esikhathini;
- ukwamukela i-spermatozoa nokuqinisekisa ukungena kwabo esibelethweni ngenhloso yokukhulelwa i-oocyte .
I-norm yomsele womlomo wesibeletho ekukhulelweni
Ubude bomsele wesibeletho ngesikhathi sokukhulelwa bufinyelela ku-4 cm.
Ukulinganisa komsele womlomo wesibeletho ngesikhathi sokukhulelwa kunqunywa ngesikhathi sokuhlolwa, kanye nokusebenza kwe-ultrasound yangaphakathi. Ngokukhulelwa okuvamile, ukuvulwa kwangaphandle komsele womlomo wesibeletho kuvaliwe kuvaliwe ngenxa yomsebenzi wemisipha yomlomo wesibeletho, okusiza umntwana ukuba ahlale esibelethweni.
Lapho usondela ekubelethweni komlomo wesibeletho uqala ukunciphisa nokunciphisa ukuhambisa ukuhamba kwengane ngokusebenzisa umsele wokuzalwa. Umsele wesibeletho, uvaliwe ngesikhathi sokukhulelwa, uqala ukwandisa. Uma kuqala ukulwa njalo, kuvula ngokuqhubekayo: ekuqaleni kuka 2-3 cm, bese kufika ku-8 cm. Izinga lokuvula umgogodla wesibeletho ngesikhathi sokukhulelwa kusiza izidakamizwa-izazi zezinkinga ukuthi zithole isikhathi esisele ngaphambi kokuzalwa kwengane. Uma isisu nesisu, esixhuma umsele womlomo wesibeletho, ovula ngo-10 cm, ukudala indlela eyodwa yobukhokho, lokhu kubonisa ukuvuleka okuphelele komlomo wesibeletho .
Uma, ngesikhathi sokukhulelwa, umsele womlomo wesibeletho ugqamile futhi wande ngaphezu kwesijwayelekile, futhi kusasele isikhathi esiningi ngaphambi kokubeletha, lokhu kuyisibonakaliso sokusongela kokukhulelwa ngaphambi kwesikhathi. Ngokuvamile, lesi simo singenzeka phakathi nokukhulelwa ngenxa yokungakwazi ukusebenza kwe-isthmico-cervical.
Ukuvulwa kwangaphambi kokuvuthwa komsele womlomo wesibeletho kungenxa yokwanda kobukhulu beqanda lesisu, elinomcindezelo okhulu kakhulu esibelethweni, okuholela ekuvuleni okuqhubekayo. Lokhu futhi kukhuthazwa ukunyakaza okusebenzayo kokubambisana futhi okunamandla
Uma kutholakala ukuthi ukutholakala kwe-Isthmico-insufficiency owesifazane kuqinisekisiwe, lo wesifazane uvame ukucelwa ukuba adonse umlomo wesibeletho noma abeke entanyeni indandatho engavumeli ukuba ivule.
Ukwengeza, owesifazane kufanele anciphise umsebenzi womzimba futhi ayeke ukuya ocansini.
Uma isibeletho sowesifazane kaningi ngethoni, udokotela unikeza iseluleko ukuthi singanciphisa kanjani. Ukwelashwa okuvimbelayo endaweni yesibhedlela nakho kungenzeka.
