1-Def: Finger like projection result from Commonest bilharzial lesion in urinary Discontinuation of the surface mucosal
oviposition of large No. of living bladder result from oviposition of large membrane of the rectum and urinary bladder
bilharzial ova inable to penetrate No. of dead ova inable to penetrate .due to bilharzial reaction
mucosa consist of connective mucosa causing compression of mucosa
tissue core containing bilharzial and ova appear dirty yellow.It appear in -: Causes: *Urinary ulcer due to
reaction covered by epithelium. form of precancerous yellow patches & ischemia over sandy patches due to pressure -1
