Abstract: Purpose: To report our outcomes with the use of a thermo-expandable metallic intraprostatic stent (Memokath) for patients with bladder outlet obstruction (BOO) secondary to prostatic obstruction, and to assess it is a feasible option for many frail and elderly men unsuitable for surgery. We reviewed patients who underwent insertion of a Memokath stent for BOO over 17 years (January 1999 to December 2015) at one regional center over a long follow-up period (median, 7 years). Patients were selected if they had obstructive urinary symptoms or urinary retention with an indwelling catheter in situ, and were ineligible for transurethral resection of the prostate (TURP) under general or spinal anesthesia. Primary outcomes assessed were the improvement in urinary symptoms and voiding parameters, as well as the ability to void spontaneously if catheterized, along with complications. One hundred forty-four patients who presented with BOO or urinary retention had a Memokath stent inserted. Ninety patients (62.5%) had a successful stent insertion with a significant difference between the median preoperative (550 mL) and postoperative residual volume (80 mL, p<0.0001). Nearly two-thirds of men (64%) returned to unassisted voiding with no increased risk of complications over time. Fifty-four patients (37.5%) experienced stent failure. Main complications requiring stent removal or repositioning were migration, occlusion, refractory urinary retention and irritative voiding symptoms. In elderly and frail men with BOO deemed unsuitable to undergo TURP, prostatic stent is a safe and practical alternative to long-term catheterization.
