Objective To evaluate the clinical utility of ultrasound-guided percutaneous catheter drainage (UPCD) in treating tuberculous psoas abscesses (TPA). Methods A retrospective analysis was conducted on 114 cases of TPA with anti-tuberculosis chemotherapy at our institution. The patients were categorized into three groups based on their treatment modalities: preoperative UPCD combined with surgery (43 cases), surgery-only (39 cases), and UPCD-only (32 cases). Surgical debridement time and blood loss were compared between the preoperative UPCD combined with surgery group and the surgery-only group. Linear regression analysis was employed to evaluate the correlation between abscess volume and both debridement time and blood loss. Furthermore, recurrence and sinus tract formation were assessed across the groups during a 24-month follow-up period. Results The preoperative UPCD combined with surgery group had significantly shorter debridement times and less blood loss compared to the surgery-only group (26.30 ± 4.14 min vs. 34.18 ± 6.30 min, p 0.01; 156.05 ± 39.47 mL vs. 237.05 ± 78.18 mL, p 0.01). Linear regression analysis revealed a positive correlation between abscess volume and debridement time in both groups, although the Coefficient B in the preoperative UPCD combined with surgery group was significantly lower than that in the surgery-only group. In the surgery-only group, blood loss was positively correlated with abscess volume, whereas no such correlation was found in the preoperative UPCD combined with surgery group. Conclusion UPCD demonstrated substantial clinical value in the management of TPA. This approach not only reduced surgical time and blood loss but also provided a minimally invasive therapeutic option, especially when combined with anti-tuberculosis chemotherapy.
