About the disease
Perinephric abscess is an accumulation of infection in the perinephric area. The most common cause of perinephric abscess is pyelonephritis. This is an infection which develops in the urinary tract and renal area. According to Clinical Advisor.com, 80% of all cases of pyelonephritis is caused by bacteria known as Escherichia coli.
Perinephric abscess can develop in people who suffer from pyelonephritis on a daily basis. Perinephric space is the location where the abscess can develop if pyelonephritis had not been treated on time.
The onset of perinephric abscess is usually gradual and slow. It may take 2 weeks before symptoms of perinephric abscess really start to be acute. Overall, there is no prevalence for perinephric abscess between men and women, it affects both sexes. People who change sexual partners very frequently and do not use protection are more likely to develop pyelonephritis and, consequently, perinephric abscess. Frequent infections of the urinary tract can be a cause of perinephric abscess as well. In men who have enlarged prostate the risk of developing pyelonephritis is greater. People with the hormonal diseases, such as diabetes, or diseases of immune system, such as HIV, are also in the risk factor of developing recurrent pyelonephritis. Nonetheless, it is not common for pyelonephritis to turn into perinephric abscess, if a person underwent proper antibiotic treatment and fought bacteria on time.
