Urinary tract infection is one of the common complications of Polycystic Kidney Disease (PKD), it includes cystitis, pyelonephritis, cysts infection and perinephric abscess. As for about 20 percent PKD patients, urinary tract infection is the earliest complication among the various complications of PKD. There are 50-70 percent of patients who are attacked by urinary tract infection once or more, and this complication is more common among women. When urinary tract infection occurs, patients had better prolong the time of taking antibiotics, however, it is hard to cure this complication completely and most of the urinary tract infection will develop to perinephric abscess and ichorrhemia, which have to be treated by surgical operations or drainage. According to clinical observations, 1/3 of PKD patients with chronic haemorrhagia are accompanied with urinary tract infection. Though patients have adopted antibiotic in time and prolonged the time of taking antibiotic, there are still some patients who are attacked by perinephric abscess and some patient even die because of this. So it is really very important to prevent and treat the urinary tract infection.
