Urethral erosion (UE) is an uncommon but potentially severe complication after suburethral synthetic slings. We aimed to identify the risk factors and diagnostic modalities of UE and also functional outcome after UE surgical management. We retrospectively analyzed eight cases of UE managed in our department between 1997 and 2007. The main presumptive risk factors of UE were excessive sling tensioning (six of eight) and postoperative urethral dilation (four of eight). The most frequent symptoms included voiding difficulties (five of eight), storage symptoms (three of eight), pain (three of eight), and recurrent stress incontinence (three of eight). UE diagnosis was accessible to introital ultrasound (five of five) and confirmed by urethroscopy (eight of eight). Surgical management was performed in seven cases and included transvaginal sling removal with urethral repair (two of seven), endoscopic transurethral sling resection (four of seven), and combined approach (one of seven). All the approaches provided good functional outcomes. Transurethral endoscopy is a mini-invasive treatment of UE and should be tried first in selected cases.
