Percutaneous bone anchor sling using synthetic mesh associated with urethral overcorrection and erosion

Percutaneous bone anchor bladder neck suspension has been recommended as a less morbid alternative to traditional anti-incontinence procedures. Specif ically, it has reported to be associated with shorter duration of hospitali zation. catheterization and urinary retention, and equivalent short-term cu re rates. Recently: there have been reports of pubic osteomyelitis associat ed with bone anchor placement, and high incidences of recurrent incontinenc e. To improve the effectiveness of the procedure the placement of a suburet hral synthetic collagen-impregnated mesh without tension was recommended. A specific device is included with the kit (Suture Spacer (Microvasive/Bosto n Scientific Corp., Natick. MA)) to prevent overcorrection of the urethro-v esical junction. We present a case of urethral erosion and complete urinary retention secondary to use of a percutaneous bone anchor sling using a Pro teGen mesh (Microvasive/Boston Scientific Corp., Natick, MA). Significant p ostoperative urethral overcorrection was noted despite intraoperative use o f the Suture Spacer.
