Prerenal acute kidney injury (acute renal failure) - causes, symptoms & pathology
Vhidhiyo: Prerenal acute kidney injury (acute renal failure) - causes, symptoms & pathology

Prerenal azotemia idanho rakakura zvisina kujairika renitrogen marara zvigadzirwa muropa.

Prerenal azotemia yakajairika, kunyanya kune vakuru vakuru uye mune vanhu vari muchipatara.

Itsvo dzinosefa ropa. Vanoitawo weti kuti vabvise marara. Kana huwandu, kana kumanikidza, kweropa kuyerera kuburikidza nemadonhwe eitsvo, kusefa kweropa zvakare kunodonha. Kana zvingasaitika zvachose. Zvigadzirwa zvemarara zvinogara muropa. Mudiki kana usina weti inogadzirwa, kunyangwe itsvo pachayo iri kushanda.

Kana nitrogen marara zvigadzirwa, senge creatinine uye urea, inovaka mumuviri, mamiriro acho anonzi azotemia. Izvi zvigadzirwa zvemarara zvinoshanda semuchetura kana zvikavaka. Vanokuvadza nyama uye vanoderedza kugona kwenhengo kuti dzishande.

Prerenal azotemia ndiyo yakajairika fomu yeitsvo kutadza muzvipatara vanhu. Chero mamiriro anoderedza kuyerera kweropa kuitsvo anogona kuchikonzera, kusanganisira:

  • Kunopisa
  • Mamiriro ezvinhu anotendera kuti mvura isabuda muropa
  • Kurutsa kwenguva refu, manyoka, kana kubuda ropa
  • Kuchenesa kupisa
  • Kuderedza kudyiwa kwemvura (kupera mvura mumuviri)
  • Kurasikirwa kweropa
  • Mimwe mishonga, yakadai seACE inhibitors (zvinodhaka zvinorapa kukundikana kwemoyo kana kuwedzerwa kweropa) neNSAIDs

Mamiriro ezvinhu ayo moyo usingakwanise kupomba rakaringana ropa kana kupomha ropa rakaderera vhoriyamu zvakare inowedzera njodzi ye prerenal azotemia. Aya mamiriro anosanganisira:


  • Kutadza kwemoyo
  • Shock (septic kuvhunduka)

Inogona zvakare kukonzerwa nemamiriro ezvinhu anokanganisa kuyerera kweropa kune itsvo, senge:

  • Dzimwe mhando dzekuvhiya
  • Kukuvadza kune itsvo
  • Kuvharika kwetsinga iyo inopa ropa kune itsvo (renal artery kuvharirwa)

Prerenal azotemia inogona kunge isina zviratidzo. Kana, zviratidzo zvezvikonzero zve prerenal azotemia inogona kunge iripo.

Zviratidzo zvekushomeka kwemvura zvinogona kunge zviripo uye zvinosanganisira chero zvinotevera.

  • Kuvhiringidzika
  • Kupera kana kusaita weti kugadzirwa
  • Muromo wakaoma nekuda kwenyota
  • Kukurumidza kupisa
  • Kuneta
  • Ruvara rweganda rakachenuruka
  • Kuzvimba

Kuongorora kunogona kuratidza:

  • Yakapunzika mitsipa mitsipa
  • Kuoma mucous membranes
  • Shoma kana isina weti mudundira
  • Kuderera kweropa
  • Yakadzika moyo basa kana hypovolemia
  • Yakashata ganda kusimba (turgor)
  • Kukurumidza kurova kwemoyo
  • Yakaderedzwa kupisa kwemhepo
  • Zviratidzo zveakanyanya itsvo kutadza

Iyi bvunzo inotevera inogona kuitwa:


  • Ropa creatinine
  • BUN
  • Urine osmolality uye yakatarwa giravhiti
  • Weti miedzo yekutarisa masodium uye creatinine mazinga uye kuongorora itsvo kushanda

Chinangwa chikuru chekurapa ndechekukurumidza kugadzirisa chisakiso itsvo isati yakanganisa. Vanhu vanowanzoda kugara muchipatara.

Intravenous (IV) zvinwiwa, zvinosanganisira ropa kana zvigadzirwa zveropa, zvinogona kushandiswa kuwedzera huwandu hweropa. Mushure mekudzoreredzwa kweropa, mishonga inogona kushandiswa ku:

  • Wedzera kuwedzera kweropa
  • Natsiridza kupomba kwemoyo

Kana munhu wacho aine zviratidzo zveakanyanya itsvo kutadza, kurapwa kunogona kusanganisira:

  • Dialysis
  • Kudya kunochinja
  • Mishonga

Prerenal azotemia inogona kudzoserwa kana chikonzero chikawanikwa nekugadziriswa mukati maawa makumi maviri nemana. Kana iyo chikonzero chisina kugadziriswa nekukurumidza, kukuvara kunogona kuitika kune itsvo (acute tubular necrosis).

Zvinetso zvinogona kusanganisira:

  • Yakakomba itsvo kutadza
  • Acute tubular necrosis (kufa kufa)

Enda kuimba yekukurumidzira kana kufonera iyo yemuno emergency emergency (se911) kana uine zviratidzo zve prerenal azotemia.


Kurumidza kurapa chero mamiriro anoderedza huwandu kana simba reropa kuyerera kuburikidza neitsvo zvinogona kubatsira kudzivirira prerenal azotemia.
