PROSTATE & BLADDER

The urinary bladder in man, being the temporary reservoir of the renal secretion, and, as such, containing the urine for longer or shorter periods, is liable to various important affections. These are dealt with in the first part of this article. The diseases of the prostate are so intimately allied that they are best considered, as in the subsequent section, as part of the same subject.

Diseases of the Bladder. Cystitis, or inflammation of the bladder, which may be acute or chronic, is due to the invasion of the mucous lining by microorganisms, which gain access either from the urethra, Cystitis. the kidneys or the blood-stream. It is easy to see how the diplococci of gonorrhoea may infect the bladder-membrane by direct extension of the inflammation, and how the bacilli which are swarming in the neighbouring bowel may find access to the urethra or bladder when the intervening tissues have been rendered penetrable by a wound or by inflammation. Sometimes, however, especially in the female, the germs from the large intestine enter the bladder by way of the vulva and the urethra.

Any condition leading to disturbance of the function of the bladder, such as enlargement of the prostate, stricture of the urethra, stone, or injury, may cause cystitis by preparing the way for bacillary invasion. The bacilli of tuberculosis and of typhoid fever may set up cystitis by coming down into the bladder from the kidneys with the urine, or they reach it by the blood-stream, or invade it by the urethra. Another way of cystitis being set up is by the introduction of the germs of suppuration by a catheter or bougie sweeping them in from the urethra; or the instrument itself may be unsterilized and dirty and so may introduce them. It used formerly to be thought that wet or cold was enough to cause inflammation of the bladder, but the probability is that this acts only by lowering the resistance of the lining membrane of the bladder, and preparing it for the invasion of the germs which were merely waiting for an opportunity. In the same way, gout or injury may lead to the lurking bacilli being enabled to effect their attack. But in every case disease-germs are the cause of the trouble, and they may be found in the urine. The first effect of inflammation is to render the bladder irritable, so that as soon as a few drops of urine have collected, the individual has intense or uncontrollable desire to micturate. The effort may be very painful and may be accompanied by bleeding from the overloaded blood-vessels of the inflamed membrane. In addition to blood, pus is likely to be found in the urine, which by this time is alkaline and ammoniacal, and teeming with micro-organisms. As regards treatment, the patient should be at once sent to bed in a warm room, and should sit several times a day in a very hot hip-bath. When he has got back to bed, a fomentation under oil-silk, or some other waterproof material, should be placed over the lower part of the abdomen. The diet should be milk (diluted with hot or cold water), barley-water, and bread and butter; no alcoholic drink should be allowed. If the urine is acid, bicarbonate of soda may be given, or citrate of soda; if alkaline, urotropine - a derivative of formic aldehyde - may prove a useful urinary disinfectant. If the straining and distress are great, a suppository of tor 2 a grain of morphia may be introduced into the rectum every two or three hours. The bowels must be kept freely open. If the urine is foul, the bladder should be frequently washed out by a soft catheter and two or three feet of india-rubber tubing with a funnel at the other end, weak and abundant hot lotions of Sanitas or Condy's fluid being used.
