Objectives. To determine the long-term safety and efficacy of the Titan endoprosthesis as a therapeutic alternative in the management of men with bladder outlet obstruction. Methods. One hundred forty-four patients (mean age, 73.5 years ± 4.2) had placement of the Titan stent. The stents were inserted under direct vision and expanded to 33 F using balloon catheter. Of the 144 patients, 59 (41%) were in urinary retention and 85 (59%) presented with moderate to severe symptoms of prostatism. Patients were assessed at baseline and in follow-up at 1, 3, 6, 12, 18, and 24 months. Parameters of evaluation included the Madsen-Iversen symptom questionnaire, peak flow rate (Qmax), postvoid residual urine volume (PVR), and incidence of adverse events. Results. At 24 months, for the retention cohort, symptoms, Qmax, and PVR were 5.21 ± 0.81, 11.34 ± 1.12 mL/s, and 31.00 ± 12.8 mL, respectively (P |
