(/) Kelly calls attention to the important points relating to theFIXED AND movable PORTIONS OF THE BLADDER. As the bladderis emptied the upper and more movable portions settle down intothe lower and more fixed portions like one saucer within another. Fig. 194. Expression of pus from the ducts of Skenes glands. (Kelly.) He observes that the location of inflammatory lesions is determinedsomewhat by the movable and fixed areas. Viewing the interior ofthe bladder with a cystoscope, the respiratory movements define themovable area as contrasted with the fixed portion. The edges where the two saucers meet form three folds, a pos-terior and two lateral folds. The apices formed by the meeting ofthese folds are known as the right and left vesical cornua. 2. Relations of the Bladder to Surrounding Structures. The trigonelies in close proximity to the anterior vaginal wall. Above this thebase of the bladder is in direct apposition to the supravaginal por-tion of the cervix. The upper half of the bladder is loosely covered 492 I>IAGNOSIS OF DISEASES OF THE URINARY SYSTEM with peritoneum. The above relations are important in operativeprocedures upon the bladder and surrounding structures. 3. Artificial Division
