Impact of Benign Prostatic Hyperplasia on Postoperative Complications and Periprosthetic Joint Infections After Total Joint Arthroplasty: A Systematic Review and Meta-Analysis.

BACKGROUND

Total joint arthroplasty (TJA) is one of the most frequently performed surgical procedures each year, offering considerable cost-effectiveness and numerous benefits. However, certain postoperative complications can be observed following TJA. While the relationship between various comorbidities and these complications has been well-documented, this study aims to specifically investigate the impact of benign prostatic hyperplasia (BPH) on postoperative outcomes.

METHODS

For this systematic review, we searched PubMed, Scopus, and Web of Science using terms like "total hip arthroplasty," "total knee arthroplasty," "BPH," and "benign prostatic hypertrophy." Screening of retrieved articles was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies comparing complications in TJA between patients with and without preexisting BPH were eligible for inclusion. Data extraction was performed on the included articles, and their quality was assessed using the Newcastle-Ottawa scale. A meta-analysis was conducted using the Mantel-Haenszel method.

RESULTS

This systematic review encompassed 4 articles evaluating TJA outcomes in men with a history of BPH, involving a total of 75,222 male cases. Among these, 17,183 cases (23%) presented with symptomatic BPH. The meta-analysis revealed that the incidence rate of periprosthetic joint infection did not significantly differ between BPH and non-BPH groups across both total hip and knee arthroplasty cases (odds ratio [OR] (95% confidence interval [CI]) = 1.28 [0.92-1.79]). However, postoperative urinary retention was significantly higher among patients with BPH (OR [95% CI] = 3.43 [2.04-5.78]). Additionally, patients with BPH exhibited a notably elevated incidence of postoperative urinary tract infection (OR [95% CI] = 2.55 [2.33-2.79]), as well as sepsis (OR [95% CI] = 1.31 [1.09-1.58]).

CONCLUSIONS

It is noteworthy that while patients with BPH are prone to certain complications, meta-analysis indicate that BPH cannot be considered a comorbidity that increases the risk of periprosthetic joint infection.
