Politano自1964年以来对720例前列腺切除术后出现尿失禁1年以上的患者进行聚四氟乙烯(Polytef,即Teflon)糊剂注射治疗。720例共注射1,000多次,平均每人注射1.4次(1～3次),每次平均注射18ml糊剂(10～20ml)。78年以前采用经会阴注射,78年以后则改为经尿道注射。经尿道注射时需识别外括约肌区,并在直视下注射糊剂。用针穿刺括约肌后注射,应环绕括约肌分别注射糊剂,使括约肌区闭合呈梗阻样表现。针应穿刺至粘膜下和浅肌层中,以免形成薄壁大疱。大疱易破裂,使糊剂漏出。
Since 1964, Politano has administered polytef (Teflon) paste to 720 patients who have been suffering from urinary incontinence for more than 1 year after prostatectomy. 720 cases of co-injection of more than 1,000 times, an average of 1.4 times per injection (1 to 3 times), each injection of 18ml average paste (10 ~ 20ml). 78 years ago by the perineum injection, 78 years later transurethral injection. Transurethral need to identify the outer sphincter area, and under direct vision injection paste. Needle puncture sphincter injection, should be injected around the sphincter paste, so that the sphincter area closed obstruction-like performance. Needles should be punctured to the submucosal and superficial myometrium, so as to avoid the formation of thin-walled bullous. Large blisters easily rupture, the paste leaks.
