RISK FACTORS FOR SYMPTOMLESS URINARY INFECTION, Zlatina Mirincheva, Iliya Popov

Summary
Introduction: Asymptomatic urinary infection (AUI) or so-called asymptomatic bacteriuria 
(AB) is the term used when microbiologically significant bacterial growth occurs in the urine 
in individuals without signs or symptoms of urinary tract infection(UTI).In view of the above, 
we can assume that AB does not require antibiotic treatment, except in very specific situations.
Objective: The aim of the present study is to conduct a thorough literature review and to define 
and summarize the risk factors for asymptomatic bacteriuria.
Results:
1. Female gender is one of the main risk factors for the development of UTI and AB.
2. Pregnancy is also a risk factor.
3. Patients with transurethral, suprapubic or nephrostomy catheters.
4. Patients on pure intermittent self-catheterization.
5. Patients with incomplete bladder emptying (residual urine > 100 ml).
6. Patients with stones in the bladder or kidneys.
7. Patients with bladder prolapse.
8. Patients with vesicoureteral reflux.
9. Patients with diabetes mellitus.
10. Transplanted patients and patients with immunosuppression.
11. Elderly and infirm patients.
12. Patients with neurogenic dysfunction of the lower urinary tract.
Conclusions: Systemic treatment of asymptomic bacteriuria(AB) is not recommended. There is 
a need to improve the diagnosis of AB and optimize the treatment of recurrent urinary tract 
infections, especially by non-antibiotic measures, to minimize antimicrobial resistance.
Key words: Asymptomic bacteriuria, urological procedures, urinary tract infections, recurrent 
urinary tract infections, immunosuppression
