Bacteremia and bacteriuria after transrectal prostatic biopsy

Area of Science:

• Urology
• Infectious Disease Prevention
• Medical Microbiology

Background:

• Transrectal needle prostatic biopsy carries a risk of infectious complications.
• Bacteremia and bacteriuria are common post-biopsy infections.
• Preventive strategies are crucial for patient safety.

Purpose of the Study:

• To compare the efficacy of parenteral gentamicin and povidone-iodine enema (P.I.E.) in preventing infectious complications.
• To evaluate P.I.E. as a standalone or adjunctive prophylactic measure.
• To assess the rates of bacteremia and bacteriuria after prostatic biopsy.

Main Methods:

• A randomized study involving 40 patients undergoing transrectal needle prostatic biopsy.
• Patients received either parenteral gentamicin, P.I.E., or a combination.
• Infectious complications, including bacteremia and bacteriuria, were monitored.

Main Results:

• P.I.E. significantly reduced bacteremia rates from 69% to 19%.
• Bacteriuria rates decreased from 32% to 9.5% with P.I.E. use.
• P.I.E. demonstrated effectiveness both alone and with gentamicin.

Conclusions:

• Povidone-iodine enema (P.I.E.) is a safe and effective method for preventing infectious complications.
• P.I.E. significantly lowers the incidence of bacteremia and bacteriuria post-prostatic biopsy.
• Incorporating P.I.E. enhances the safety of transrectal needle prostatic biopsy procedures.
