近年来,由于对尿路有选择性作用的α受体阻滞剂及5α还原酶抑制剂等药物的临床应用,引起下尿路梗阻、有器械或手术处理指征的前列腺病例数已大大减少。然而,约20％的患者在初次就诊或通过药物无效时仍需手术治疗,越来越多的患者经过多年服药治疗,治疗初期症状可缓解,而前列腺体积却不断增大,最终需行手术。在作者所在医院对经尿道前列腺电切术(TURP)的病例进行统计后发现,切除前列腺的平均重量由1990年的30g上升到1996年的40g。
In recent years, the clinical application of drugs such as α-blockers and 5α-reductase inhibitors that have a selective effect on the urinary tract has led to a significant reduction in the number of cases of lower urinary tract obstruction with indications for instrumentation or surgery . However, about 20% of the patients still need surgical treatment on first visit or through drug ineffectiveness. More and more patients take medicine for many years and the initial symptoms can be alleviated. However, the volume of the prostate increases but eventually the operation is needed. Statistics of the cases of transurethral resection of the prostate (TURP) at the author’s hospital found that the average weight of the prostatic ablation increased from 30 g in 1990 to 40 g in 1996.
