Abstract

"Purpose: Recently, incidence of prostatic cancer has increased due to the development of the prostatic cancer screening test. The common procedure is the transrectal technique, whereby following prophylactic antibiotics, a core biopsy needle is passed through the rectum. Complications of prostate biopsy are perineal tenderness, hematuria, hematospermia, rectal bleeding, fever and sepsis. We estimated the risk factors and pathogens of urinary tract infections after transrectal ultrasound guided biopsy of prostate. Materials and Methods: A retrospective chart review was conducted of patients, who had been treated for urinary tract infection (UTI) after 365 prostatic biopsy between January 2009 and January 2012. We analyzed the parameters including past medical history, kind of antibiotics, number of biopsies, pathology, urine culture and blood culture. Results: Hematuria was most common (5.4%), while UTI occurred in 4.9% of the cases. The symptoms of UTI were dysuria and fever. Average admission day was 6.2 days. E. coli was identified in 7 patients. It was observed that higher numbers of biopsies correlated with UTI. The other conditions investigated didn't correlate with complications after biopsies. Conclusions: We considered that UTI was a rare complication of prostatic biopsy and complications after biopsy were low. A higher number of fragments taken during biopsies showed a correlation with UTI. "
