 it enters the bladder, it lies immediately in front of the upper 

 part of the anterior vaginal wall (Fig. 225). When the 

 bladder is distended and the vagina is narrow the posterior 

 angles of the bladder may extend beyond the lateral borders 

 of the vagina ; in such cases the relations of the ureters to the
