摘要

This study establishes a novel method for draining male rectovesical pouch abscesses using ultrasound guidance with a biplane endocavitary probe via a transperineal approach. Traditional transabdominal puncture routes carry risks of injuring vital structures. In a consecutive retrospective analysis of 15 patients, this technique achieved a 100% success rate with single-pass efficiency and no major complications. Crucially, postoperative indicators showed significant reductions in body temperature (mean Δ = − 1.8 °C, P < 0.001), white blood cell count (mean Δ = − 9.2 × 10⁹/L, P < 0.001), and granulocyte fraction (mean Δ = − 18.4%, P < 0.001), confirming rapid resolution of the infectious process. These results indicate that for pelvic abscesses where standard drainage routes fail, the ultrasound-guided biplane probe transperineal approach provides a safe, effective, and anatomically adapted solution, potentially broadening therapeutic options for complex pelvic collections.
