Background And Aim:
Infection or bleeding after transrectal prostate biopsy remains a concern of both patients and urologists. We explored the risk of association of certain co-morbidities with both complications.
Patients And Methods:
Using the Taiwan National Health Insurance Research Database, we identified patients undergoing prostate biopsy from 2000 to 2013. We used logistic multivariable regression to search for associations between post-biopsy hospitalization and the two co-morbidities within a year after biopsy.
Results:
Among 3,601 prostate biopsies, 100 infections (3.77%) and 52 (1.44%) bleeding-related emergency room visits and hospitalizations were recorded within 30 days after biopsy. The group having the biopsy as an inpatient exhibited older age (p < 0.0001) and a higher percentage of having diabetes mellitus (p = 0.015) than patients without either complication. The logistic multivariable regression analysis showed that urinary retention, freedom from diabetes, and performance as an outpatient procedure were independent risk factors for infection-related hospitalization (odds ratios 1.81, 1.96, and 1.72; p values 0.031, 0.037, and 0.010, respectively).
Conclusion:
Patients with a recent history of urinary retention have a higher probability of infection-related hospitalization after prostate biopsy.
Insights
Urinary retention increases infection risk after prostate biopsy. This study identified key comorbidities associated with post-biopsy complications, aiding urologists in patient risk assessment.
Area of Science:
- Urology
- Medical Informatics
- Public Health
Background:
- Transrectal prostate biopsy is associated with infection and bleeding risks.
- Patient and urologist concerns exist regarding these post-procedural complications.
Purpose of the Study:
- To explore the association between comorbidities and post-transrectal prostate biopsy complications.
- To identify risk factors for infection and bleeding after prostate biopsy.
Main Methods:
- Utilized the Taiwan National Health Insurance Research Database (2000-2013).
- Analyzed 3,601 prostate biopsies using logistic multivariable regression.
- Investigated associations between post-biopsy hospitalization and comorbidities within one year.
Main Results:
- 3.77% infection and 1.44% bleeding-related hospitalizations occurred within 30 days.
- Inpatient procedures, older age, and diabetes mellitus were associated with complications.
- Urinary retention, freedom from diabetes, and outpatient procedures were independent risk factors for infection-related hospitalization.
Conclusions:
- Patients with a history of urinary retention face a higher risk of infection post-prostate biopsy.
- Identifying specific comorbidities can help predict and potentially mitigate post-biopsy complications.
