Nekunonzi kusagadzikana kwetsvo, fetus haikwanisi uye inofa mumavambo ekutanga ekudzivirira, nepo fetus ine kusagadzikana kwakaoma kunowanzopona. Inenge 10% yevana vanoberekwa vane zvingava zvakakomba zvakakomba zve genitourinary system.
Kubudirira kwetsvo
Intrauterine inetso yekukudziridza inoratidzika zvakaoma zvikuru. Primitive usiku (metanephrosis) yakaiswa kune rumwe rutivi rwechevhiri. Zvadaro, nekuwedzera kwechikamu chezasi che fetus, chimwe nechimwe chazvo chinotanga kufamba kwayo kusvika kune imwe nzvimbo yekupedzisira kwayo (kusimuka) panguva imwecheteyo kutendeuka kumativi ayo (kutenderera). Chimwe chikonzero chinokosha chekuwedzera kufambiswa kwetsvo dzepakutanga ndiko kufanana kwavo nemardiments everereters. Kutama kana kutenderera kunetseka kuri pamwoyo wezvinonyanya kufadza zvepfungwa dzenyoka. Mukuwedzera, mukugadzirisa kwekuwedzera kweprauterine, zvinokwanisika kubatanidza zvose zvitsva zvitsva nekuumbwa kwepfungwa imwe huru.
Kidyo anomalies
Iphiri anomalies inoratidzwa nemitatu mikuru mikuru:
• Chiremera chinogona kukanganisa imwe kana mairi mafungiro maviri.
• Kukanganisa kwakasiyana-siyana kunogona kusanganiswa mune imwe tsvo.
• Zvimwe zvisingaoneki hazvina maturo, asi migumisiro yezvipingamupinyi, zvakadai sehutachiona, inobatsira pakuonekwa kwechirwere. Mune mamiriro ekusaremara kwakanyanya, kukundikana kwechirwere kunogona kukura nokukurumidza kana nguva pfupi mushure mokuzvarwa kwemwana.
Anomalies emamiriro ekutsva haasi pasi pekugadziriswa. Izvi zvinosanganisira:
• Tsvete yepelvic inenge iri mukati memhepo. Inoumbwa sechikonzero chekutyora kwekufamba kune imwe nzira mukugadzirisa intrauterine. Zvizhinji zvezvakaipa izvi hazvina maturo.
• Kuora kweiyo. Zvichida mumashanduro akasiyana-siyana, inonyanya kufanana ndeye mafungiro akafanana nehashti. Nzira yekufambisa inowanzosaputsika.
• I "kidzo" yakagadzikana sechimiro chechimiro chisina kusimba, chinonzi clumpy chiya chiri munharaunda. Inoumbwa panguva yekubatanidzwa kwetsvo uye kuputsa kwekufamba. Tsitsi yakadaro haigoni kukonzera zviratidzo zvehutano.
• Muchinjikwa dystopia weputsvo. Imwe tsvete iri kune rumwe rutivi rworudyi, pedyo neimwe tsvo.
• Tsora dzeTracracic. Inowanikwa mumapfupa echifuva, iyo inogona kuwirirana nekuputsa kwekusimudzirwa kwechirafu (septum fibrous-muscular separation the thoracic and stomach cavities). Ichi ndicho chisingadikanwi chisina kuwanikwa, chirongwa chokugadzirisa icho chiri chakaoma zvikuru.
• Kukwegura (kuberekwa kusina kuberekwa) kwetsvo. Iko kunoonekwa, kana embryo isina kuisa ruvara, iyo inhengo yehurogenital inofanira kukura. Bhabatari renal agenesis inotungamirira kurufu rwembryo.
Iveter is a muscle tube through which the urine from the kidneys flows into the swelling. Mune matanho ekutanga ekubudirira, huwandu hwenhema huripo, hunowanzokonzera kukanganiswa munharaunda yemuguta. Kushungurudzika kwekunyengedzwa kwewareteric primordia (primitive renal drainage system) ne mesonephros (yepure embryonic yepsoyo) inotungamirira kusungwa kwekuvandudzwa kweiyo (aplasia). Mune dzimwe mamiriro ezvinhu, kusagadziriswa kwepfungwa kunowanikwa nekuumbwa kwechistic sangano (dysplasia) yeAplasia uye renal dysplasia kazhinji
Kuparadzaniswa kwemashure
Iwareteric ovula inogona kuwirirana uye inokonzera kuwanda kwemafuro akavharidzira madota ayo anotungamirirwa pasi pamwe chete. Dzimwe nguva zvinokwanisika kutarisa izvi zviri kunze nekuvandudzwa kwehutano syndrome. Imwe mhando yakasiyana-siyana yekusalysa inowanikwa apo budhu hwemhando mbiri dzinenge dzichikura huchikura mumumvuri - munyaya iyi, kuwirirana kwepimpomo kunoitika. Mumwe nomumwe wavo ane ureter yake, iyo inopinda mumukanda payo pachake kana kubatana nomumwe. Kushushikana hurongwa hwekugezera kwehvo hunowanzosangana nemarwadzo kubva pakukandira urinho kubva kune chepasi kusvika kune chikamu chepamusoro chepvo.
Dhiyabhorosi yeusrethral septum
Somugumisiro wehutachiona hwekuvandudzwa kweeusthral septum (pakati pezvinyorwa zvezvikamu zvepabonde uye rectum), pane dzimwe nguva pane kuwedzera kwechistic kwechikamu chechireve chinoputika mukati memwenje yechipfuva-ireterocele. Chikamu chiduku che ureterocele chinowanzoitika kakawanda uye kazhinji hachikonzeri matambudziko. Kuwedzera kunokosha kunogona kuva nzvimbo yekuumbwa kwematombo emuyuniti. Chirwere chakaipisisa chechirwere chinotyisa chinotungamirira kukuvhiringidzika. Kazhinji ureterocele, urine reflux, uye mafungiro akarovererwa anosanganiswa mune mumwe murwere. Kugara uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uine chikamu chemukati.
• mavheti ekupedzisira ekupedzisira-kuumbwa kwemafuro maviri emuchembera weusrethra ye urethra, iyo inotungamirira kune kukanganisa kukwidza;
• hypospadias - kusagadziriswa kwekuvandudzwa kwechiremba, umo mazaruriro ayo kunze anowanikwa pasi pepenisheni kana kunyange pamucheka, panzvimbo yekuzarura musoro wepenisi.
Rare anomalies
• Kubuda kwechidimbu-chiremera chemukati wekunze kwechidzitiro uye mudumbu remuviri pasi pechizivo. Muchiitiko ichi, kuora kwepenis, kusagadzikana kwematsetse mumaprotum uye inguinal hernia, uye mumusikana - cleavage ye clitoris anoonekwa zvakare.
• Cloaca kugoverwa muviri wakaremara umo kune kuparadzana kwechidzitiro mukati memakumi maviri ehafu (mune imwe neimwe iyo iyo inopinda mukati) uye kusanyanya kufambira mberi kwepenisi. Zvinokwanisika kuisa musikana muduku uye anus, uyewo kusanganiswa kwemaitiro ane congenital cerebrospinal hernia.
• Epispadia - chiremera chepamusoro serusvingo rwechiremba. Kana ichibatanidzwa ne-sphincter yemukaka, murwere angave anotambura nekuvhenekera kusagadzikana. Kutanga kufungidzirwa nekugadziriswa kwekukanganisa kwakakosha zvikuru kune varwere vane hutano husina hanya hwetsvo uye chikafu. Maitiro anoshandiswa munzvimbo dzakakura dzakasiyana-siyana uye ruzivo rwakawanda mukurapa kusagadzikana kwehurogenital system muvana. Mumaoko ane unyanzvi, zvizhinji zvekusawirirana kwechidzitiro zvinogona kugadziriswa zvakabudirira.
