What's up guys? Today we're going to talk about acute cystitis and acute

pylenophritis. We're going to talk about how these patients will

present the physical exam, what are the common pathogens, and finally how do we

treat these patients? Acute cystitis can be defined when the normal

sterile tissue, the bladder becomes infected

causing a lower urinary tract infection,

whereas acute pylenophritis can be defined as an infection

within the renal perencoma, chalousase,

or pelvis of the kidney resulting in an upper urinary

trapped infection. In addition, acute cystitis can occur alone or along with acute

pylenophritis. But what causes these infections most commonly?

Well, in women, lower urinary tract infections occur when uropathogens

from our own feces colonized within the vaginal enteroidus,

from there they can then travel into the urethra and into the bladder

causing acute cystitis. From here if the uropathogens continue to ascend

up the urotors to the kidneys pylenophritis can develop.

Pylenophritis can also be caused from bacteria

if the pathogen seeds within the kidneys.

The most common causes of acute uncomplicated cystitis

and pylenophritis occur mainly from E. coli 75 to 95 percent of the time.

Occasionally you will have other species bound in the normal flora of our stool causing these infections

such as Proteous Marabolas, Klepsiala pneumonia, and Staphylococcus saprophyticus.
