At the base of the bladder a pouch forms behind thehypertrophied prostate in which a portion of the urine lies and cannotbe expelled. This urine which is left behind at each urination is calledresidual urine, and it readily decomposes, giving rise to an inflam-mation of the bladder, or cystitis. All forms of cystitis may, throughmigration of the organisms along the ureters into the pelvis of thekidney, give rise to a condition known as pyelonephritis, formerlycalled surgical kidney, the effect upon the system being that of anacute or chronic toxemia, called urosepsis. The seminal vesicles and vasa deferentia are covered by peri-toneum close to the entrance of the ureters into the bladder. Thev

Around the neck of the bladder there is a rich plexus of veins knownas the prostatic plexus, which frequently become so congested as tobecome varicose, giving rise to either spontaneous hemorrhages intothe b
