Purpose: The UroLume (American Medical Systems, Minnetonka, Minnesota) endoprosthesis has been commercially available since 1990 and has been advocated for use in men with urethral stricture disease and detrusor-sphincter dyssynergia due to spinal cord injury. Despite reports of its success and ease of removal, we have noted management problems in several complex cases. Materials and Methods: We retrospectively analyzed the outcome of 10 men who required several additional procedures or experienced complications following UroLume placement. Results: Of the patients 4 had detrusor-sphincter dyssynergia and 6 had urethral stricture disease. All patients with detrusor-sphincter dyssynergia required hospitalization for management of urosepsis within 4 to 10 months of stent placement, and all 4 experienced stent migration requiring placement of a tandem stent (3), bladder neck resection (3) or sphincterotomy (1). Two men were in retention following placement of a second stent and required stent explantation. Of the other 6 men 2 had bulbar and 3 had membranous urethral disease, and 1 had a severe bladder neck contracture following radical retropubic prostatectomy. Strictures recurred within the stent lumen in all 6 men and/or adjacent to it in 3. At least 1 repeat procedure was required in all 6 men (within 6 months in 5), and 1 experienced significant bleeding during open explantation which required perineal urethrostomy. Conclusions: In our referral experience stent migration and recurrent stenosis were noted following UroLume insertion. Placement of a tandem stent was associated with urethral obstruction. In many cases these adverse outcomes may be secondary to improper patient selection. Therefore, judicious use of the UroLume stent and proper case selection are essential since stent removal is not always straightforward.
