Abstract: 【Abstract】〓Objective〓To investigate nonbacterial cystitis in the upper urinary tract obstruction. Methods〓137 cases with upper urinary tract obstruction were included in the study. Chronic nonbacterial cystitis was confirmed by mid-stream urine culture(MSU), cystoscopy, biopsy, and ureteroscopy. The incidence, diagnosis and treatment of nonbacterial of nonbacterial cystitis were investigated retrospectively. Results〓Thirty-two cases of chronic nonbacterial cystitis were found in 137 cases with upper urinary tract obstruction(23.4%), in which 27 cases were caused by upper urinary lithiasis obstruction(19.7%), 5 cases by non-calculus obstruction(3.6%). Of 32 cases,glandular cystitis had 23 cases, proliferative cystitis 3 cases, vesical leukoplakia lesion 6 cases. Moreover, the nonbacterial cystitis was complicated with chronic ureteritis and ureteral polyps in 11 cases. In the nonbacterial cystitis cases, MSU was positive in 3 cases (all caused by Escherichia coli), while in 96 cases without nonbacterial cystitis, MSU was positive in 11 cases, including 10 cases of E.coli infection, one of staphylococcus aureus infection and one of staphylococcus epidermidis infection..Sixteen nonbacterial cystitis patients were followed up for 3 months post-treatment of relief of obtrucion..The patient got recovery. Conclusion〓The upper urinary tract obstruction may be associated with high incidence of nonbacterial cystitis.
