Postoperative Imaging after Surgical Repair for Pelvic Floor Dysfunction.

Pelvic floor dysfunction encompasses an extremely common set of conditions, with various surgical and nonsurgical treatment options. Surgical options include injection of urethral bulking agents, native tissue repair with or without bioabsorbable or synthetic graft material, placement of synthetic midurethral slings or use of vaginal mesh kits, and mesh sacrocolpopexy procedures. Numerous different synthetic products with varied imaging appearances exist, and some of these products may be difficult to identify at imaging.

Three-dimensional ultrasonography to assess long-term durability of periurethral collagen in women with stress urinary incontinence due to intrinsic sphincter deficiency.

Objectives: To investigate the natural history of periurethral collagen injection (PCI) over time using serial three-dimensional ultrasonography (3DUS) of the urethra as an objective measure.

Methods: Retrospective chart review was performed for all patients who underwent PCI between February 1999 and February 2003. All had been diagnosed with stress urinary incontinence due to intrinsic sphincter deficiency without urethral hypermobility, had follow-up data including two or more 3DUS scans within 1 year or more, and had undergone no additional PCIs (ie, remained clinically improved).
