目的：探讨前列腺增生症（ＢＰＨ）射频治疗失败的原因及对手术的影响。方法：回顾性分析３８例ＢＰＨ患者射频治疗失败后前列腺切除术的情况及术后前列腺的病理特征。结果：前列腺中叶突入膀胱３０例（７８．９％），前列腺与包膜不同程度粘连１８例（４７．３％），术后并发症１２例（３１．６％），前列腺组织呈慢性炎症２１例（５５．３％）。结论：ＢＰＨ患者射频失败与前列腺大小及突入膀胱程度密切相关，射频后手术难度较大，应注意防治并发症。
Objective: To investigate the causes of failure of radiofrequency ablation of benign prostatic hyperplasia (BPH) and its influence on surgery. Methods: A retrospective analysis of 38 cases of BPH patients after radiofrequency ablation of prostatectomy and postoperative pathological features of the prostate. Results: There were 30 cases (78.9%) in the middle of prostate and 18 cases (47.3%) in different degrees of prostate and capsule adhesion. Postoperative complications occurred in 12 cases (31.6%) and prostate tissue was chronic inflammation Example (55.3%). Conclusion: The failure of radiofrequency in patients with BPH is closely related to the size of the prostate and the degree of invasion into the bladder. After the radiofrequency, the operation is difficult and the complication should be controlled.
