Risk Factors in Urinary Tract Infection

Abstract

Background: There are many intrinsic and extrinsic risk factors, which are the leading causes of urinary tract infection. This study was conducted to investigate the relationship of various risk factors to urinary tract infection. Material and Methods: This study was performed from March 1990 –September 1990. A total of 100 patients with urinary tract infection were studied. Detailed history and physical examination was carried out in each patient. Fifty-seven patients were male while 43 female. The age range was 1-70 years. Results: In majority of patients (15%) urolithiasis was associated with urinary tract infection. Benign prostate hypertrophy was the second (10%) leading risk factor causing urinary tract infection. Catheterization and pregnancy almost equally contributed (4% and 5%). Minor contribution was made by risk factors like tumor in the kidney, non-functional kidney, kinking of ureter, kidney transplant, myxoedema, diabetes, etc. In almost sixty percent cases the risk factor could not be identified and no cause was detected. Conclusion: The chances of urinary tract infection increase in the presence of risk factors.
