E = F – R + S

•. E : ekskresi•. F : filtrasi•. R : reabsorpsi•. S : sekresi

Pembentukan urine

Glomerulus

GFR:Kecepatan filtrasi glomerulus

Page 9: Fisiologi Ginjal & System urinary

Regulasi GFR

GFR bergantung pada :

1. tekanan arteri

2. aliran aferent

3. aliran eferent

Cafeine vasodilatasi aferent Aliran aferent GFR diuresis

Beser (ngompol) Sfingter urethra eksterna otot rangka

kendalikan BAK Sfingter urethra eksterna tak mampu

berkontraksi tak mampu tahan BAK Penyebab : trauma tulang belakang,

jatuh terduduk Terapi : latihan fisioterapi

Creatinin & Gagal ginjalCreatinin & Gagal ginjal

Clearance creatinin & kadar creatinin Clearance creatinin & kadar creatinin darah merupakan indikator fungsi darah merupakan indikator fungsi ginjalginjal

Clearance creatinin Clearance creatinin ↓ : fungsi filtrasi ↓ ↓ : fungsi filtrasi ↓ kadar creatinin darah kadar creatinin darah

Kadar creatinin darah Kadar creatinin darah & clearance & clearance creatinin ↓ creatinin ↓ Dx : gagal ginjal Dx : gagal ginjal

Penyebab gagal ginjal : aliran glomerulus↓ Penyebab gagal ginjal : aliran glomerulus↓ misal : batu ginjal & shock misal : batu ginjal & shock
