Abstract

We present a systematic review providing estimates of the overall and regional burden of infectious complications following prostate biopsy. A directly standardized prevalence estimate was used because it reflects the burden of disease more explicitly. Complications included sepsis, hospitalization, bacteraemia, bacteriuria, and acute urinary retention after biopsy. There were 165 articles, comprising 162 577 patients, included in the final analysis. Our findings demonstrate that transrectal biopsy was associated with a higher burden of hospitalization (1·1% vs. 0·9%) and sepsis (0·8% vs. 0·1%) compared to transperineal biopsy, while acute urinary retention was more prevalent after transperineal than transrectal biopsy (4·2% vs. 0·9%). The differences were statistically non-significant because of large heterogeneity across countries. We also demonstrate and discuss regional variations in complication rates, with Asian studies reporting higher rates of sepsis and hospitalization.

Increasing hospital admission rates for urological complications after transrectal ultrasound guided prostate biopsy.

Robert K. Nam, Refik Saskin, Yuna Lee … (2012)

Transrectal ultrasound guided prostate biopsy is widely used to confirm the diagnosis of prostate cancer. The technique has been associated with significant morbidity in a small proportion of patients. We conducted a population based study of 75,190 men who underwent a transrectal ultrasound guided biopsy in Ontario, Canada, between 1996 and 2005. We used hospital and cancer registry administrative databases to estimate the rates of hospital admission and mortality due to urological complications associated with the procedure. Of the 75,190 men who underwent transrectal ultrasound biopsy 33,508 (44.6%) were diagnosed with prostate cancer and 41,682 (55.4%) did not have prostate cancer. The hospital admission rate for urological complications within 30 days of the procedure for men without cancer was 1.9% (781/41,482). The 30-day hospital admission rate increased from 1.0% in 1996 to 4.1% in 2005 (p for trend <0.0001). The majority of hospital admissions (72%) were for infection related reasons. The probability of being admitted to hospital within 30 days of having the procedure increased 4-fold between 1996 and 2005 (OR 3.7, 95% CI 2.0-7.0, p <0.0001). The overall 30-day mortality rate was 0.09% but did not change during the study period. The hospital admission rates for complications following transrectal ultrasound guided prostate biopsy have increased dramatically during the last 10 years primarily due to an increasing rate of infection related complications.

The incidence of fluoroquinolone resistant infections after prostate biopsy--are fluoroquinolones still effective prophylaxis?

Joseph Feliciano, Ervin Teper, Michael Ferrandino … (2008)

Fluoroquinolones have been shown to decrease infective complications after prostate biopsy. However, fluoroquinolone resistance is emerging. We quantified contemporary rates of infective complications and the incidence of fluoroquinolone resistant infections after prostate biopsy under fluoroquinolone prophylaxis. We retrospectively evaluated the records of 1,273 patients who underwent prostate biopsy at New York Harbor Veterans Affairs Hospital from January 2004 to December 2006. Patients received levofloxacin or gatifloxacin. Using the Veterans Affairs computerized patient record system we reviewed all patient visits within 1 month after prostate biopsy. Visits were queried for infective symptoms. Positive cultures were evaluated for resistance patterns. The annual and overall incidence of infective complications and fluoroquinolone resistant infections was calculated. Of 1,273 patients 31 (2.4%) presented with infective symptoms after biopsy. The overall incidence of fluoroquinolone resistant infections was 1.2% (15 cases). When stratified by year, there were statistically significant increases in the incidence of infective complications and fluoroquinolone resistance from 2004 to 2006. Of the positive cultures those from 89% of patients yielded Escherichia coli and 90% were fluoroquinolone resistant. Fluoroquinolone resistant E. coli were also resistant to gentamicin in 22% of cases, trimethoprim/sulfamethoxazole in 44%, piperacillin in 72% and ampicillin in 94%. However, 100% sensitivity was demonstrated for amikacin, ceftazidime and ceftriaxone. Fluoroquinolones are still effective as antibiotic prophylaxis for prostate biopsies but there is an increase in infective complications and fluoroquinolone resistance. When patients present with post-prostate biopsy infective symptoms, almost 50% are associated with fluoroquinolone resistant pathogens. Empirical treatment with ceftriaxone, ceftazidime or amikacin should be initiated until culture specific therapy can be implemented.

Fluoroquinolone-resistant E. coli in intestinal flora of patients undergoing transrectal ultrasound-guided prostate biopsy--should we reassess our practices for antibiotic prophylaxis?

K Slabbaert, D Steensels, Egbert van Nes … (2012)

Although the estimate of the incidence of sepsis following transrectal ultrasound-guided prostate biopsy (TRUSPB) is low, fluoroquinolone-resistant infections after prostate biopsy are being increasingly noted. This study was aimed at determining the prevalence of faecal carriage of fluoroquinolone-resistant Escherichia coli strains before TRUSPB and at evaluating potential predisposing risk factors. The incidence of sepsis after prostate biopsy was determined, and our routine practice for antibiotic prophylaxis for TRUSPB was evaluated. A prospective study was conducted in 342 consecutive patients undergoing prostate biopsy between December 2009 and July 2010. Before TRUSPB, a rectal swab was cultured. The correlation between the presence of fluoroquinolone-resistant strains and plausible risk factors was investigated by the use of a questionnaire. Of the 236 patients included, 22.0% (52/236) harboured ciprofloxacin-resistant E. coli strains. The use of fluoroquinolones in the 6 months before biopsy was associated with an increased risk of faecal carriage of fluoroquinolone-resistant E. coli strains (p <0.01). Faecal carriage of fluoroquinolone-resistant E. coli strains was an important risk factor for infectious complications after TRUSPB (p <0.01). In conclusion, a significant number of patients have faecal carriage of fluoroquinolone-resistant E. coli strains (22.0%) before TRUSPB. The use of fluoroquinolones in the previous 6 months before biopsy is a risk factor for faecal carriage of fluoroquinolone-resistant E. coli strains and for infectious complications after TRUSPB. Hence, the universal administration of fluoroquinolones should be reconsidered. © 2011 The Authors.
