Urologie
H1: anatomie
- Anatomie en fysiologie uw stelsel
o Blaas  laag slijmvlies  in lege toestand in plooien ligt
o Bij vulling  plooien verstrijken
o Onderaan blaas  2 uitmondingen van urineleiders
o Glad spierweefsel  gaat over in sfincter of sluitspier  urethra
o Mechanisme van urineren
 Sterke vulling en plooien verstrijken
 Weerstand v/d sfincter daalt
 Sfincter ontspant
 Contractie v/d blaasspier
 Plassen = blaasspier ontspant zich
o Sfincter zorgt voor geen urine verlies tijdens inspanning

- Mechanisme van continentie
o Blaasdruk
 Blaas: dubbele functie
 Reservoir bij vulling
 Trekt samen bij urineren
 Urineren: vulling blaas +/- 500ml 3 à 6u

o Weerstand
 Verbinding v/d blaas met urethra
 Steun van bekkenbodemspieren
