自1990年7月～1991年6月采用国产 F20JK—4D 金属管隐蔽耐压气囊扩张管(简称扩张管)扩张治疗精阜增生症6例,效果良好.报告如下。见附表临床资料操作方法病人取截石位,消毒铺巾,1%丁卡因10ml 尿道粘膜麻醉。将消毒扩张管定位翼固定在内管距复合胶囊远端24.2cm 处即等于外套管长度(附图)。扩张管从尿道口插入使导头入膀胱。右食指从肛门触摸并定于前列腺尖部下缘,缓慢抽拉外套管,当外套管近端移至指压处,外套管推拉环恰好与定位翼衔接,如果未衔接,只需将内管适当朝膀胱推进即可,这时复合胶囊准确定位在外括约肌以上的后尿道段。固定外套管,用气筒缓缓将气压由0升至0.3mpa,维持10～12分钟,扭开放气阀,压力表指针降至0时拔出扩张管,尿道内留置 F18Foley’s 管2天。
From July 1990 to June 1991 using domestic F20JK-4D metal tube concealed pressure balloon dilation tube (dilatation tube) dilation in the treatment of fine Fu hyperplasia in 6 cases, the results are as follows. See Schedule Clinical data Operation method Patients take lithotomy position, disinfection shop towels, 1% tetracaine 10ml urethral mucosa anesthesia. The sterility of the expansion tube positioning wing fixed at 24.2cm from the distal end of the composite tube is equal to the outer sleeve length (with photos). The dilation tube is inserted from the urethra so that the introducer enters the bladder. The right index finger from the anus touch and set at the lower edge of the prostatic apex, slowly pulling the outer tube, when the outer tube proximal to the acupressure, the outer tube push and pull ring just convergence with the positioning wing, if not convergence, simply the inner tube appropriate Propellant toward the bladder, then accurate positioning of the composite capsule in the external sphincter urethra above the segment. Fix the outer tube and slowly raise the pressure from 0 to 0.3mpa with a gas cylinder for 10 to 12 minutes. Tighten the deflation valve. When the pressure gauge drops to 0, pull out the expansion tube. Leave the F18 Foley’s tube in the urethra for 2 days.
