The other 20 cases divided into 7 cases delivered by C.S (group D) and 13 cases with vaginal delivery (group B) three of them delivered by forceps delivery (group C). All cases subjected to history taking, clinical examination including P.R and investigation in the form of E.M.G to levator ani muscle and external anal sphincter, PNTML on the right and left side and manonetrip study at rest and at squeezing on the immediate postnatal period and 2 months later.
