Ubuwazi ukuthi izinso zingenye yezitho ezimangalisayo emzimbeni wethu? Zifana 'nohlelo lokuhlunga' emzimbeni wethu. Insizakalo eyenziwa yizinso ukuhlunga yonke imfucuza engadingekile kanye nobuthi emzimbeni nokugcina umzimba uphilile ayinakuqhathaniswa. Ngakho-ke, lezi zinso ezimbili eziyigugu zidinga igazi elihle ukuze zenze umsebenzi wazo kahle. Namuhla, sizokhuluma ngomthambo wegazi oyinhloko oletha igazi. Lokhu sikubiza ngokuthi 'i-Renal Artery'.
Kalula nje, iyini le 'Renal Artery'?
Kulula kakhulu. Igama elithi 'Renal' lisho 'okuphathelene nezinso'. 'I-Artery' iwumthambo wegazi othwala igazi elihlanzekile (igazi elinomoya-mpilo) lisuka enhliziyweni liye emzimbeni wonke. Khona-ke 'I-Renal Artery' ibhekisela emthambo wegazi oyinhloko othwala igazi ngqo lisuka enhliziyweni yethu liye ezinso.
Njengoba sinezinso ezimbili, sinemithambo emibili yezinso.
- Umthambo wezinso ongakwesokudla unikeza igazi ezinso ezifanele.
- Umthambo wezinso wesobunxele, ohlinzeka ngegazi ezinso zesobunxele.
Cabanga ngalokhu: uhlelo lokujikeleza kwegazi lomzimba wethu lufana nenethiwekhi yemigwaqo. Ngakho-ke, umthambo wegazi oyinhloko oqala enhliziyweni, i-aorta, ufana nomgwaqo omkhulu. Iminyango emibili emikhulu eya edolobheni ebizwa ngokuthi izinso ezivela kulowo mgwaqo omkhulu yimithambo yezinso.
Yimuphi umsebenzi obaluleke kakhulu wale mithambo yegazi?
Umsebenzi oyinhloko nowukuphela kwale mithambo yegazi ukunikeza izinso igazi. Kodwa lokho akuwona umsebenzi omncane. Cabanga nje, umzuzu ngamunye, cishe ingxenye yendebe yegazi idlula ezinso zakho ngale mithambo emibili yezinso. Ngosuku, izinso ezimbili eziphilile zinamandla okuhlunga amalitha angaba ngu-140 egazi. Le mithambo emibili yezinso yileyo eqhubeka nokunikeza leli nani elikhulu legazi ezinso.
Izinso zithatha leli gazi elingenayo, zilihlunge, bese zihlukanisa udoti namanzi engeziwe kulo. Bese zikhipha udoti njengomchamo. Igazi elihlanziwe libe selibuyiselwa emzimbeni ngomunye umthambo wegazi (umthambo wezinso). Ngakho-ke, uyabona, yonke le nqubo incike ekuhlinzekweni kwegazi okuvela emithanjeni yezinso.
Kwenzekani kuleli gazi elingaphakathi kwezinso? Ake sithathe uhambo oluncane sibone?
Ake sibheke nje ukuthi kwenzekani ngokulandela igazi elingena ezinso lisuka emthanjeni wezinso. Lokhu kufana nenqubo eyenzeka ngaphakathi kwefektri enkulu.
1. Isango eliyinhloko: Umthambo wezinso ungena ezinso endaweni ebizwa ngokuthi 'i-renal hilum'. Lokhu sikubiza ngokuthi 'isango eliyinhloko lezinso'. Eminye imithambo yegazi, imizwa, njll. ingena futhi iphume ezinso ngale sango.
2. Izihlungi ezincane (Izihlungi):Uma usungaphakathi kwenso, lo mthambo wegazi omkhulu uyahlukana ube yimithambo yegazi eminingi emincane. Ekugcineni, leli gazi liya ezihlungini ezincane ezibizwa ngama-nephron. Kukhona cishe isigidi salezi zi-nephron enso eyodwa.
3. I-Glomeruli: Ngaphakathi kwe-nephron ngayinye kunemithambo yegazi emincane ebizwa ngokuthi i-glomeruli. Yilapho imfucuza namanzi engeziwe egazini kuhlungwa khona bese kudluliselwa engxenyeni elandelayo. Kodwa-ke, izinto ezibalulekile egazini, njengeprotheni namaseli abomvu egazi, azidluli esihlungini futhi zihlala egazini.
4. Uketshezi oluhlungiwe: Imfucuza ehlukanisiwe kanye namanzi kuhamba ngemigudu emincane ebizwa ngokuthi ama-tubules. Phakathi nalolu hambo, izakhamzimba namaminerali oketshezini oludingwa ngumzimba kuyamuncwa futhi kufakwe egazini.
5. Umphumela wokugcina: Imfucuza engafuneki esele kanye namanzi kwakheka njengomchamo .
6. Ukubuya kwegazi elihlanziwe: Phakathi naleso sikhathi, igazi elihlungiwe nelihlanziwe liphuma ezinso lidlule emthanjeni wezinso bese liqala ukujikeleza emzimbeni wonke futhi.
Ukuze yonke le nqubo isebenze kahle, umthambo wezinso kumele ube nempilo futhi ungaphazanyiswa.
Yiziphi izinkinga ezingaba khona ngalezi mithambo yegazi ebalulekile?
Njengeminye imithambo yegazi emzimbeni wethu, imithambo yezinso nayo ingaba nezinkinga. Inkinga enkulu ukuthi le mithambo yegazi incishiswa ukunqwabelana kwamafutha ne-cholesterol (lokhu sikubiza ngokuthi 'i-plaque'). Lesi simo ngokwezokwelapha sibizwa ngokuthi 'i-atherosclerosis'.
Okwenzekayo lapha kufana nendlela ipayipi lamanzi, ngokuhamba kwesikhathi, elivaleka ngayo ngokugqwala nokungcola, okubangela ukuthi imbobo epayipini iwele.
Uma umthambo wezinso uncipha ngale ndlela, siwubiza ngokuthi 'i-Renal Artery Stenosis' . Lesi yisimo esibi kakhulu esithinta le mithambo yegazi.
Kwenzekani uma umthambo wezinso uncipha?
Cabanga ukuthi kwenzekani uma ucindezela ipayipi lamanzi? Amanzi ayaphoqeleka ukuphuma ngokucindezela okukhulu, akunjalo? Yilokho okwenzekayo lapha. Lapho umthambo wegazi uncipha, inani legazi eliya ezinso liyancipha. Ngaleso sikhathi, izinso zicabanga ukuthi umfutho wegazi emzimbeni wehlile. Ngenxa yalokho, izinso ziqala ukukhiqiza ama-hormone akhulisa umfutho wegazi. Lokhu kubangela ukuthi umfutho wegazi emzimbeni wonke ukhuphuke.
Ithebula elingezansi libala eminye yemiphumela emibi engaba khona ngenxa 'ye-renal artery stenosis'.
| Inkinga/isimo | Incazelo elula |
|---|---|
| Umfutho Wegazi Ophakeme | Ukwehla kokugeleza kwegazi ezinso kungabangela umfutho wegazi ophezulu emzimbeni. Odokotela bakhathazeka kakhulu ngalokhu uma umuntu osemusha eba nomfutho wegazi ophezulu noma uma enomfutho wegazi ophezulu okunzima ukuwulawula ngemithi ejwayelekile. |
| Isifo Sezinso Nokwehluleka | Uma izinso zingatholi igazi elanele ngokuhamba kwesikhathi, ukusebenza kwazo kwehla kancane kancane futhi ekugcineni kungaholela ekuhlulekeni kwezinso. |
| Ukwehluleka Kwenhliziyo | Umfutho wegazi ophakeme njalo wenza inhliziyo isebenze kanzima. Ngokuhamba kwesikhathi, inhliziyo iba buthakathaka futhi ingaholela ekuhlulekeni kwenhliziyo. |
| Isifo sohlangothi | Umfutho wegazi ophezulu wonakalisa imithambo yegazi ebuchosheni, okwandisa ingozi yokushaywa yisifo sohlangothi ngokuyibangela ukuba iqhume noma ivaleke. |
Siyigcina kanjani imithambo yegazi ezinso zethu iphilile?
Ukugcina impilo yale mithambo yezinso kuyinto esingayenza thina ngokwethu. Ikakhulukazi uma umthambo wegazi uvalekile ngaphansi kuka-60%, lesi simo singalawulwa ngokushintsha indlela yokuphila kanye nokudla.
Ukulandela lezi zinyathelo ezingezansi akugcini nje ngokuhle ezinso zakho, kodwa futhi nakumzimba wakho wonke.
| Okufanele ngikwenze | Ulwazi olwengeziwe |
|---|---|
| Ukudla okunempilo kwenhliziyo | Yamukela ukudla okune-cholesterol ephansi, uwoyela, usawoti kanye noshukela. Nciphisa ukudla okuthosiwe, ukudla okunamafutha, iziphuzo ezinoshukela, kanye nokudla okucutshunguliwe ngangokunokwenzeka. Faka izithelo eziningi, imifino, ubhontshisi kanye nokudla okucebile nge-fiber. |
| Ukuzivocavoca njalo | Thola okungenani imizuzu engama-30 yokuzivocavoca okunamandla aphakathi cishe izinsuku eziningi zesonto. Noma yini efana nokuhamba, ukugijima, noma ukugibela ibhayisikili ilungile. |
| Ukugcina isisindo esinempilo | Ukukhuluphala ngokweqile kuyimbangela enkulu yezinkinga zemithambo yegazi. Zama ukugcina isisindo esinempilo ngobude bakho. |
| Ukulawula ezinye izifo | Uma unezimo ezifana nesifo sikashukela, umfutho wegazi ophakeme, noma i-cholesterol ephezulu, kubalulekile ukuzilawula kahle ngaphansi kweseluleko sikadokotela. |
| Ukugwema ukubhema | Ukubhema kuwumonakalo omkhulu emithanjeni yegazi. Yeka ukubhema nemikhiqizo kagwayi ngokuphelele. |
| Uma unesifo sezinso | Uma usuvele unesifo sezinso, kungadingeka unciphise ukudla okuneprotheni ne-potassium eningi njengoba kuceliwe udokotela wakho. |
Kufanele ubonane nini nodokotela?
Uma unesinye noma ngaphezulu kwalezi zimpawu ezilandelayo, ungazinaki futhi ubone udokotela wakho ngokushesha. Lezi zingase zibe izimpawu zenkinga yezinso.
- Igazi emchameni.
- Ukuvuvukala (ukuvuvukala) komzimba, ikakhulukazi imilenze, amaqakala, nobuso.
- Ubunzima bokuchama noma ukuchama njalo.
- Isicanucanu, ukuhlanza, kanye nokwehlisa isisindo ngaphandle kwesizathu esibonakalayo.
- Ukukhathala ngokweqile noma ikhanda elibuhlungu njalo ngaphandle kwesizathu.
Lezi zimpawu azibangelwa njalo inkinga yemithambo yezinso. Kodwa-ke, kubalulekile ukuthola imbangela nokufuna ukwelashwa okufanele.
Umlayezo Wokuya Nawe Ekhaya
- Umthambo wezinso uwumthambo wegazi oyinhloko othwala igazi lisuka enhliziyweni liye ezinso. Ubalulekile ekusebenzeni kahle kwezinso.
- Le mithambo yegazi ingancipha ngenxa ye-cholesterol kanye nokuqongelela kwamafutha (i-Renal Artery Stenosis). Lesi yisimo esibi kakhulu.
- Ukuvaleka kwemithambo yezinso kungaholela ezimweni ezifana nomfutho wegazi ophakeme ongalawuleki, isifo sezinso, ukuhlaselwa yinhliziyo, kanye nesifo sohlangothi.
- Le mithambo yegazi ingagcinwa iphilile ngokulandela ukudla okunempilo, ukuzivocavoca njalo, ukugwema ukubhema, nokulawula izifo ezifana nesifo sikashukela kanye nomfutho wegazi ophakeme.
- Uma uhlangabezana nanoma yiziphi izimpawu ezihlobene nezinso, ungazinyangi futhi uxhumane nodokotela wakho ngokushesha ukuze uthole iseluleko.
