Purpose of review
The insertion of prostatic stents in the treatment of lower urinary tract symptoms in men secondary to benign prostatic obstruction from benign prostatic hyperplasia
has proven to be an effective modality in properly selected patients. We review the current literature on the role of prostatic stents in the treatment of bladder outlet obstruction secondary to benign prostatic hyperplasia
Permanent stents such as the Urolume and the Memokath offer efficacious and safe treatment alternatives for men with bladder outlet obstruction from benign prostatic hyperplasia
who are deemed high surgical risks for traditional transurethral resection of the prostate. When removal of permanent prostatic stent is necessary, the design of the Memokath allows for an easier removal than that of the Urolume. Temporary stents are being investigated as a means to treat the transient bladder outlet obstruction frequently observed after minimally invasive thermotherapy procedures aimed at treating benign prostatic obstruction, with both biodegradable and retrievable stents shown as successful modalities for this indication.
Prostatic stents remain an option to treat men with benign prostatic obstruction/bladder outlet obstruction; however, stent migration remains an obstacle to their widespread use. The key to obtaining optimal outcomes in men with benign prostatic hyperplasia
is careful patient selection and experience with proper stent deployment.
