摘要

攝護腺內高溫療法是利用特殊導管，以無線電頻率之能量導入攝護腺內，將其加溫至100°C而造成攝護腺凝固性壞死。本研究中總共有八位病人因慢性尿滯留合併高手術危險性接受攝護腺內高療法。治療效果以尿流速測量、症狀量表、生活品質量表來評估。
所有病人在局部麻醉下的忍受性均相當良好。在八位病人中，有六位(75%)在平均9.2天(範圍由1至21天)後恢復解尿。平均最高流速為9.8±3.2毫升/秒(範圍由5.9至14)。一位病人因追蹤時間太短(一週後改採其他治療)，另一位則因逼尿肌能不良及老年性癡呆而仍無法自主性解尿。我們認為攝護腺內高溫療法對於由攝護腺肥大引起之尿滯留是有效的。尤其特別適合有高手術危險性的老年病人。

The transurethral needle ablation (TUNA)of the prostate was performed in 8 patients in chronic urinary retention, all of whom were a poor surgical risk.
A special catheter device was usedto deliver low-level radiofrequency energy to heat tissue within the prostate to 100°C. After treatment, uroflowmetry, symptom score and quality of life score were evaluated.
Tolerance of the procedure with topical anesthesia was satisfactory. Of the 8 patients, 6(75%) resumed voiding within a mean time of 9.2 days(range1-21). The mean maximal flow rate was 9.8±3.2ml/s(rangel5.9-14). Failure to void was associated with a decompensated detrusor function. We conclude that TUNA is effective for patients with urinary retention due to benign prostatic hyperplasia. It seems particularly suitable for treating elderly patients with a high surgical risk.
