Urologists often perform procedures on anterior urethra, which is one of the most sensitive parts in male patients. The aim of the present study was to determine the efficacy of intracorpus spongiosum anesthesia during procedures on anterior urethra in the outpatient clinic.
A dosage of 3 mL of 1% lidocaine was slowly injected into the glans penis of 51 male patients. Immediately following injection, they underwent different procedures on anterior urethra. The subjective experience of pain in the patients was assessed by questionnaire according to a pain scale.
Forty-seven patients (92.16%, 47/51) had zero pain and four cases (7.84%) had either minor or moderate discomfort, which was limited and tolerable. The anesthetic effect is immediate and has been very satisfactory. All the procedures (mean duration, 33 min), were successfully completed under the intracorpus spongiosum anesthesia. The act of injection into the glans caused instantaneous minor pain in 45 patients (88.23%, 45/51), moderate pain in four patients and no pain in two patients. There were no serious complications with this anesthetic technique, although two cases had instantaneous trance during injection of lidocaine.
Minor procedures on anterior urethra in an outpatient setting with intracorpus spongiosum anesthesia are generally painless, safe, simple, successful and inexpensive compared to those performed in a hospital.
泌尿外科医生经常对前尿道进行手术操作，而前尿道是男性患者最敏感的部位之一。本研究的目的是确定门诊行前尿道手术时海绵体腔内麻醉的效果。
将3毫升1%利多卡因缓慢注入51例男性患者的阴茎头。注射后立即对他们进行不同的前尿道手术。根据疼痛量表通过问卷调查评估患者的主观疼痛体验。
47例患者（92.16%，47/51）无疼痛，4例患者（7.84%）有轻微或中度不适，但程度有限且可耐受。麻醉效果立竿见影，非常令人满意。所有手术（平均持续时间33分钟）均在海绵体腔内麻醉下成功完成。向阴茎头注射时，45例患者（88.23%，45/51）有瞬间轻微疼痛，4例患者有中度疼痛，2例患者无疼痛。尽管有2例患者在注射利多卡因时有瞬间恍惚，但该麻醉技术无严重并发症。
与在医院进行的手术相比，门诊采用海绵体腔内麻醉进行前尿道小手术通常无痛、安全、简单、成功率高且费用低廉。
