Prostatic UroLume Wallstent for urinary retention due to advanced prostate cancer: a 1-year followup study.

We attempt to clarify the long-term clinical reliability of the prostatic UroLume Wallstent in the treatment of urinary retention due to advanced prostate cancer. The stent was placed in 11 stage D prostate cancer patients at high surgical risk and with urinary retention unrelieved by total androgen blockade. At preoperative urethroscopy, the bladder neck and verumontanum were clearly visible and not massively infiltrated by tumor. All patients voided spontaneously at the end of the procedure. At 1 year maximum flow nomograms demonstrated the definite relief of bladder outlet obstruction and of related symptoms in the 10 cases evaluated. As expected, the stent had no evident effect on the natural history of prostate cancer. There were no major complications. Bladder outlet obstruction due to advanced prostate cancer and unrelieved by conventional medical therapy can be treated safely and effectively by the prostatic UroLume Wallstent.
