Mune fetus, chimiro chetsvo kubva pamwedzi mina yekuzvitakura chakafanana nekugadzirisa kwepvo yekare yakaberekerwa mwana - pane parenchyma mune ramangwana maitiro ehurumende uye maitiro akawandisa. Iyo urinary excretion system inosanganisira makapu nemapanga, apo makapu anotsemuka. Zvakare, urini inopinda mumucherechedzo uye chikafu chechi fetus, iyo inowedzera kakawanda pazuva.
Tsitsi dziri mumucheche dzinotanga kushanda kubva pamasvondo makumi matanhatu ekuberekwa. Uye pachipiri chekuongorora kuongorora kwema ultrasound mumasvondo 18-21 ekuberekwa, zvakakosha kutarisa kana kune mairi tsitsi dzose uye kana kune hutano husina kunaka hwetsvo, urinary tract uye chikwata.
Chii chinonzi hydronephrosis mu fetus?
Munguva ye embryogenesis, chero chetatogenic chinogona kukonzera kuberekwa kusakanganiswa kwepvo, asi iyowo inowanikwa umo hutano hunoita basa guru. Uye kana pakanga pane zvirwere zvakasiyana-siyana zvephenyo mujenasi, saka vanofanira kubhadhara zvakanyanya kurongwa hwe fetus.
Hydronephrosis ikuwedzera kwezviputi zvetsvo uye pelvis nemugine. Kana iyo fetus iine kuwedzerwa kwemapapiro kubva pa5 kusvika 8 mm mukati memasvondo makumi maviri ekuberekwa kana kubva pa5 kusvika 10 mm mushure memasvondo makumi maviri, izvi hazvizi hydronephrosis, asi kazhinji fetus inobatsira mafungiro amai kuita basa, izvo zvisingagoni kurarama nemutoro uye munyaya iyi, itsvo dzevakadzi vane pamuviri dzinofanira kuongororwa.
Asi kana kuongorora kwe-ultrasound kwemasvondo makumi maviri kunowanikwa kuwedzera mapirasi anopfuura 8 mm, uye mushure memasvondo makumi maviri-makumi matatu, ipapo iyi ndiyo hydronephrosis. Kazhinji kazhinji iyo ndeye-imwechete uye inofanirwa pane imwe nhanho kuderedza mutsara we urinary kwakaitika.
Kana hydronephrosis yeinso yakarurama inowanikwa mumucheche, ipapo mhirizhonga inogona kuitika pamwero wekodzero yakarurama yemapapiro mukati mumiriri, mune chero chikamu chemukati wakarurama kana kusvika pakupinda mune chidzitiro. Izvo zvinogona zvakare kuti ureter abve kubva kuhvo zvisina kunaka kana kuti abvumirane nemumwe mudziyo.
A hydronephrosis yemakumbo akasiyiwa ari mu fetus anoitika nekuda kwekudzivirira kwakafanana kuruboshwe.
Hydronephrosis inokuvadza nokuti nekuwedzera, zvinokwanisika kufambisa parenchyma nemurine kusvikira yaparadzwa zvachose, mushure mokunge hydronephrosis haingazovizve, asi inso haigoni kuponeswa. Nokudaro, kurapwa kunowanzokurumidza: kana hydronephrosis iduku - mushure mokuberekwa kwomwana, uye kana zvichidikanwa - uye panguva yekuzvitakura pamutsvo we fetus (kubuda kwenguva kwemuti, kunoteverwa ne-post-partum plastiki chirurgic) kunokosha.
