仔细选择25例尿道狭窄用颊粘膜片移植一期尿道成形术。对资料较完整和得到足够随访的20例进行了研究。年龄23～65岁。能确定狭窄原因的17例,其中淋病和(或)与器械操作有关的16例,会阴部创伤1例。16例以前经过扩张,或窥视下尿道内切开治疗,分别为13和8例次,多为重复操作,2例以前行端端吻合尿道成形术失败。最初用颊粘膜片移植治疗的4例是由于广泛的尿道周围海绵体纤维化,造成可触及的尿道狭窄和经尿道镜发现短的、苍白色的、紧贴于ch17号镜鞘的狭窄。狭窄位于球部8例、悬垂部尿道12例,其长度为1～2cm。所有的狭窄都伴有明显的海绵体纤维化,又不能多次行尿道切开。
Careful selection of 25 cases of urethral stricture with buccal mucosa transplantation stage urethroplasty. Twenty patients with complete data and adequate follow-up were studied. Age 23 ~ 65 years old. Seventeen patients were able to determine the cause of stenosis, including gonorrhea and / or 16 cases related to device operation and 1 case of perineal trauma. Of the 16 patients who had undergone dilation or peeing under urethral incision, they were 13 and 8 cases, respectively. Most of them were repeated operations and 2 cases failed to undergo end-to-end urethroplasty. The first four cases treated with buccal mucosal transplantation were due to extensive periapical fibrosis of the corpus cavernosum, resulting in palpable urethral stricture and transurethral resection of the short, pale, narrow stenosis of the sheath of ch17. Narrow in the ball in 8 cases, 12 cases of hanging over the urethra, the length of 1 ~ 2cm. All stenoses are accompanied by significant cavernous fibrosis, and can not be repeatedly urethral incision.
