[16] Urinary retention in females is uncommon, occurring 1 in 100,000 every year, with a female-to-male incidence rate of 1:13. It is usually transient.
Urostomy is most commonly performed after cystectomy, such as may be necessary in, for example, bladder cancer.Other indications include severe kidney disease, accidental damage or injury to the urinary tract, surgical complications because of non-related pelvic or abdominal surgery, congenital defects that cause urine to back up into the kidneys, or urinary incontinence.
Conditions involving low output of urine are oliguria (< 400 mL/day) and anuria (< 100 mL/day). The first step in urine formation is the filtration of blood in the kidneys. In a healthy human, the kidney receives between 12 and 30% of cardiac output, but it averages about 20% or about 1.25 L/min.
Hold your urine for too long, and—ready or not—it's going to start coming out. "The longer the bladder is full, the greater the likelihood of leakage of urine," Dr. Fromer says.

In humans, the kidneys together receive roughly 20% of cardiac output, amounting to 1 L/min in ...
End-staged renal diseases as well as chronic kidney diseases increase the overall risk of individuals developing pneumonia due to the interactions between the kidneys and the lungs. [3] Both organs are targets of similar systematic diseases and loss of normal function of one organ can induce the disregulation of and abnormalities within the other.
