To compare pain, discomfort, complications and convalescence during and after vasectomy performed conventionally or using the Li 'no-scalpel' method.
Between March 1993 and May 1995, 256 men were vasectomized at two city hospitals in Copenhagen; half of the patients underwent the conventional technique at one hospital and the remaining half the Li method at the other. The two groups were matched for the time at which they underwent surgery and therefore for the duration of follow-up. A questionnaire was sent to all patients, in which they scored pain and discomfort using a 10 cm visual analogue scale (VAS). The reproducibility of measurements was tested on 10 patients who had answered the same questions 1.5-2 years earlier.
Men vasectomized using the Li method experienced less pain at rest after the first week (P = 0.05) and less use of analgesics (P < 0.001), had fewer infections (P = 0.0015) and contacts with their physician (P = 0.0078) than those conventionally vasectomized. There were no significant differences between the groups for pain and discomfort during surgery and in the first week after vasectomy, frequency of bleeding, haematoma, oedema, granuloma, pain at activity, absence from work, vasectomy failure by sperm analysis, sexual activity and satisfaction with the cosmetic result (all P > 0.05).
Vasectomy using the Li method reduced post-operative pain, the use of analgesics, the frequency of infections and contacts with a physician when compared with the conventional procedure.
比较传统输精管切除术与“李氏无刀”法输精管切除术过程中及术后的疼痛、不适、并发症及恢复情况。
1993年3月至1995年5月期间，哥本哈根两家城市医院对256名男性实施了输精管切除术；一半患者在一家医院接受传统技术手术，另一半在另一家医院接受李氏手术方法。两组患者手术时间匹配，因此随访时间也相同。向所有患者发送了一份问卷，让他们使用10厘米视觉模拟量表（VAS）对疼痛和不适进行评分。对10名在1.5 - 2年前回答过相同问题的患者进行了测量再现性测试。
与接受传统输精管切除术的男性相比，采用李氏方法进行输精管切除术的男性在第一周后休息时疼痛较轻（P = 0.05），使用镇痛药较少（P < 0.001），感染较少（P = 0.0015），与医生接触较少（P = 0.0078）。两组在手术期间及输精管切除术后第一周的疼痛和不适、出血频率、血肿、水肿、肉芽肿、活动时疼痛、缺勤、精液分析显示的输精管切除失败、性活动及对美容效果的满意度方面均无显著差异（所有P > 0.05）。
与传统手术相比，采用李氏方法进行输精管切除术可减轻术后疼痛、减少镇痛药使用、降低感染频率及与医生的接触。
