To evaluate the results of single-stage new technique of perineal urethroplasty with double breasting of the urethra and bladder neck and sphincteroplasty in female patients with epispadias.
We have treated 4 patients with severe female epispadias (male/female ratio 6:1) since 1991. They presented at the age of 3, 11, 12, and 23 years. Perineal urethroplasty with double breasting, sphincteroplasty, and genitoplasty was done in 3 cases. Cohen's cross-trigonal reimplantation with bladder neck reconstruction was done in the fourth patient who had an ectopic ureter, but the patient required perineal urethroplasty and genitoplasty because of partial incontinence. The urethral plate and bladder neck was mobilized from the surrounding tissue to the bladder neck. A urethral mucosal strip of about 5 to 10 mm was denuded from the bladder neck to the end of urethral plate on one lateral edge, and the urethral plate and urethral mucosa was tubularized over a 12F catheter. Urethroplasty was done with double breasting of the urethral muscle margins starting from inside the bladder neck downward to the neomeatus with corporoplasty, sphincteroplasty, and genital reconstruction.
Of the 4 patients, 3 were fully continent during the day with a dry interval of 4 to 5 hours. One of the 3 patients was partially continent and had nocturnal enuresis, which responded to anticholinergic. The fourth patient with bladder neck reconstruction was partially incontinent initially but became continent after perineal urethroplasty.
Our technique of one-stage perineal urethroplasty increases the urethral and bladder neck resistance, as well as the bladder capacity, all factors important for continence. This is a simple and effective method for the development of both continence and cosmesis in female epispadias repair.
评估采用尿道和膀胱颈双乳房状成形术及括约肌成形术的单阶段会阴尿道成形术新技术在女性尿道上裂患者中的治疗效果。
自1991年以来,我们共治疗了4例严重女性尿道上裂患者(男女比例为6:1)。她们的年龄分别为3岁、11岁、12岁和23岁。3例行会阴尿道成形术、双乳房状成形术、括约肌成形术及生殖器成形术。第四例患者有异位输尿管,行科恩氏交叉三角区再植术及膀胱颈重建术,但因部分尿失禁,患者还需行会阴尿道成形术及生殖器成形术。将尿道板和膀胱颈从周围组织游离至膀胱颈。在一侧边缘从膀胱颈至尿道板末端剥除约5至10毫米的尿道黏膜条,将尿道板和尿道黏膜在一根12F导管上管状化。通过从膀胱颈内部向下至新尿道口的尿道肌边缘双乳房状成形术,同时行阴茎成形术、括约肌成形术及生殖器重建来完成尿道成形术。
4例患者中,3例白天完全控尿,排尿间隔为4至5小时。3例患者中有1例部分控尿且有夜间遗尿,使用抗胆碱能药物后有改善。第四例行膀胱颈重建术的患者最初部分尿失禁,但在会阴尿道成形术后变为控尿。
我们的单阶段会阴尿道成形术技术增加了尿道和膀胱颈阻力以及膀胱容量,这些都是控尿的重要因素。这是一种在女性尿道上裂修复中实现控尿和美容的简单有效方法。
