What is urinary Tract Infection?
Urinary tract infection (UTI) refers to the range of manifestations and severity of illness associated with microbial colonization of the genitourinary tract that extends from the renal cortex of the kidney to the urethral meatus.
It is the most common bacterial infection accounting for 25% of all infections and it occurs in all age groups in both male and female. Incidence of UTI is higher in female as compared to male. The reason behind this is probably due to various clinical entities like distance of urethra and anus is short, hormonal effects & behavior pattern.
UTI is the
commonest bacterial infection affecting females mostly in the developing
countries like Nepal due to illiteracy, lack of proper hygiene & sanitary
facilities. They are always at risk of infections caused by various
microorganisms. It is predicted that about 50% of women will be infected with
urinary pathogen in their lifetime, and one in three women will receive
antimicrobial agent for the treatment of UTI.
How UTI is diagnosed?
UTI is diagnosed with a simple method of culture in the microbiological laboratory. The patient has to give a urine sample which is processed in the laboratory. Bacteria is isolated and the appropriate antibiotic for particular bacterium is selected through antibiotic susceptibility test.
Why culture is in need before antibiotic therapy?
Clinicians are experiencing the presence of various cases of antibiotic resistance to common antibiotics especially in urinary pathogens in both developed and developing countries. The high level of resistance is mainly because of excessive and inappropriate use of antimicrobial agents. So, medical professionals should always consider prescribing antimicrobial agent based on antibiotic susceptibility.
What are signs and symptoms of UTI?
Lower abdominal pain
Frequency of micturition
Red color urine
