progression of pyelonephritis. Pyelonephritis is an infection of the upper urinary tract- usually the renal pelvis and renal tubules. The infection is caused by pathogens, 80% of pyelonephritis cases are caused by E.Coli bacteria, which is present in the rectum. (Shankel, 2007). The bacteria can enter the urethra and quickly infect the bladder. This infection is more common in women because they have shorter urethras- just 2 inches compared to 8 inches in men, the bacteria can move into the bladder and cause an infection much faster in women. Usually urine clears the urethra of bacteria, but in women the E.Coli can move up the urethra and into the bladder very quickly, and there will already be many bacteria cells in the bladder by the time the person urinates, not completely clearing the urinary system of bacteria. (Nabili, 2008). Pyelonephritis causes symptoms such as frequent and painful urination, both of which the patient presented. Obstruction of any part of the urinary tract can also cause infection. Since urine clears the urinary tract of bacteria as it moves down during urination. Reflux of urine from the bladder back up into the ureters, or from the ureters back up into the kidney can also cause pyelonephritis. This can happen during pregnancy; as the baby grows, the uterus expands and puts pressure on the adjacent bladder and ureters. This can obstruct the flow of urine and also cause the backflow of urine back up the ureters from the bladder, allowing the bacteria to grow and move up the ureters into the kidney much more efficiently. (Shankel, 2007). Pyelonephritis is very common in pregnant women, up to 8% of pregnant women will
