The Clinical Analysis Of 136 Old Female Patients With Urinary Tract Infection

Objective:To investigate the characteristic,predisposing factors and treatment of urinary tract infection(UTI)in old female patients, in order to improve clinical treatment and reduce recurrence rate. Methods:The 136 old female patients with UTI in our hospital from 2000 to 2004 were analysed retrospectively. Results:(1)Clinical manifestations: there were only 39.7% patients have obvious urinary irritation symptoms. (2)Patients mostly had immune hypofunction or functional or organic urethremphraxis because of other diseases such as diabetes , lithangiuria , tumor and so on. (3)The Gram-negative bacteria was still common bacteria from UTI, with 61.8% of E.Coli.(4)The drug resistance rate of E.Coli to ampicillin and ciprofloxacin was respectively 88% and 69%,the drug resistance rate of imipenem was the lowest,secondly were amikacin and piperacillin/tazobactam. CONCLUSIONS Predisposing factors of UTI in old female patients were concerned with insufficiency of estrin,other diseases that lead to immune hypofunction and functional or organic urethremphraxis. The one of its characteristics is that symptoms of some patients are not typical .E.Coli is the principal pathogenic bacteria,imipenem ,piperacillin/tazobactam and amikacin are experimental choice. We should pay attention to some problems, such as the bacterial drug resistance, urethremphraxis,gynecological disease and immune hypofunction when patients relapse, in order to reduce the recurrence rate we shoud control or remove these predisposing factors.
