作者设计了一种放置于前列腺部尿道的自留导管,用以治疗10例前列腺增生所致的尿潴留,取得了较好的效果。方法这种新的尿道内自留导管两端膨大呈Malecot形,16F,有45,55及60毫米三种长度,可经22F膀胱镜或特制的安放装置将该导管放在膀胱颈及前列腺部尿道内。病人取膀胱截石位,经留置导尿管向膀胱内注入生理盐水150毫升后拔管,尿道内注入10毫升利多卡因凝胶,用阴茎夹阻塞尿道末端5分钟,然后将远端装有尿道内导管的膀胱镜鞘送入膀胱,这时有盐水流出,膀胱镜后退到膀胱颈部时,盐水则停止对
The authors designed a catheter placed in the prostatic urethra, used to treat 10 cases of urinary retention caused by benign prostatic hyperplasia, and achieved good results. Methods The new urethral indwelling catheter was expanded at both ends in Malecot shape, 16F with 45, 55 and 60 mm lengths. The catheter was placed over the bladder neck and the prostate gland via a 22F cystoscope or a specially-made placement device Urethra. The patient took the bladder lithotomy position, after catheter indwelling catheter injected into the bladder 150 ml of normal saline extubation, 10 ml of lidocaine gel injected into the urethra, the penis clamp obstruction of the urethral 5 minutes, then the distal The urethral catheterization of the cystoscope sheath into the bladder, when saline outflow, cystoscopy back to the bladder neck, the saline is stopped
