We present our results with periurethral polytetrafluoroethylene (Polytef) injection after urethral reconstruction in 20 female patients with urinary incontinence. These patients have failed previous urethral reconstructive procedures to cure incontinence, including Young-Dees-Leadbetter bladder neck reconstruction, transvaginal urethroplasty, transvaginal urethral plication and vesical flap urethroplasty. Of the patients 4 also underwent a bladder augmentation procedure. After polytetrafluorethylene injection 10 patients (50 per cent) were cured of the incontinence, 2 (10 per cent) had marked improvement from the preoperative condition, 5 (25 per cent) had definite improvement but still wear pads for protection and 3 (15 per cent) had no change from the preoperative condition. Bladder pressure recordings did not demonstrate a difference in results among patients with detrusor stability or instability. Periurethral polytetrafluoroethylene injection remains a valuable procedure in the management of persistent incontinence after bladder neck and urethral reconstruction.
我们报告了20例女性尿失禁患者在尿道重建术后行尿道周围聚四氟乙烯（Polytef）注射的结果。这些患者先前的尿道重建手术未能治愈尿失禁，包括Young-Dees-Leadbetter膀胱颈重建术、经阴道尿道成形术、经阴道尿道折叠术和膀胱瓣尿道成形术。其中4例患者还接受了膀胱扩大术。聚四氟乙烯注射后，10例患者（50%）尿失禁治愈，2例（10%）较术前状况有明显改善，5例（25%）有一定改善但仍需使用护垫保护，3例（15%）与术前状况无变化。膀胱压力记录显示逼尿肌稳定或不稳定的患者之间结果无差异。尿道周围聚四氟乙烯注射在膀胱颈和尿道重建术后持续性尿失禁的治疗中仍是一种有价值的方法。
