OBJECTIVES: This European multicenter study was aimed to assess the clinical reliability of a modified prostatic UroLume Wallstent (American Medical System, Minnetonka, MN) in the treatment of 135 healthy patients with symptomatic benign prostatic hyperplasia. METHODS: Ninety-one patients who were obstructed but still voiding spontaneously and 44 patients who had an indwelling catheter were treated by placement of a modified stent. RESULTS: A significant improvement in mean peak flow rates and residual urine volumes was maintained throughout follow-up. Both obstructive and irritative voiding symptoms were significantly improved after placement of the stent, although a greater amelioration was seen in obstructive symptoms. The rate of patients reporting erections increased after stent insertion. Eighty percent of sexually active patients reported the maintenance of antegrade ejaculation postoperatively. A greater than 80% epithelialization of the stent was seen in 28 patients (100%) examined at the 18-month follow-up. Long-term complications were seen in 51 patients (38%). Twenty-one of these patients had the stent removed due to intractable detrusor instability, stent encrustation, stent migration, or persistence of obstruction due to prominent median lobe, understenting, or severe hyperplasia of the epithelium of the prostatic urethra. In 6 of them another stent was reimplanted while the others were treated surgically. CONCLUSIONS: Although this modified stent was abandoned due to an unacceptable rate of complications, this study demonstrates that bladder outlet obstruction in healthy patients with benign prostatic hyperplasia can be successfully relieved by the placement of a UroLume Wallstent.
