Do prostatic stents solve the problem of retention after transurethral microwave thermotherapy?

Temporary nonmetallic stents offer an alternative to an indwelling catheter for the management of voiding problems after heat-based therapies for benign prostatic hyperplasia. Patient comfort is improved, and they are able to void immediately after the procedure. Unlike a catheter, stents function on the principle of active drainage. Thus, a functioning detrusor muscle is imperative for stent success. Single-center clinical trials have reported encouraging results; however, predictable success criteria are yet to be established. Multicenter trial data are awaited.
