Abstract: Purpose:To determine the long-term safety and efficacy of the MemothermTM endoprosthesis as a therapeutic alternative in the management of men with BPH.Method:MemothermTM urethral stent was applied to thirty-eight men (mean age 77 years. Range 62-87 ) with symptoms and urodynamics suggestive of BPH.Results:Follow-up was lost in five patients. All but two patients with follow-up were eventually able to have spontaneous urination. Stents were removed from two patients because of dislocation. Prostatectomy was required in three patients at 15, 30 and 32 months respectively. Three patients resorted to indwelling catheterization after two years due to recurrence of symptoms. Information on 15 patients between 31 and 48 months follow-up was obtained. IPSS score was21.2±4.3.Conclusion:The long-term results from our trial unveiled that the Titanium-alloy memorial stents was an effective therapeutic alternative for patients having urinary retention with short life expectancy or operative contraindication.
