Abstract
Background: This review aims to identify and summarize the current literature on the use of prostatic stents or nitinol devices as minimally invasive techniques for the management of lower urinary tract symptoms (LUTS) resulting from benign prostatic hyperplasia (BPH).
Methods: A comprehensive search of the literature was conducted until October 2023. Only original articles written in English were considered for inclusion. This review has been registered in PROSPERO (registration number CRD42023474884).
Results: Thirty-eight articles were included (2618 patients). Generally, the risk of bias was deemed as high or very high. The most frequently investigated stents were the UroLume, followed by the Memokath/Memotherm. The mean age was 72.01 ± 5.6 years, with a mean prostate volume of 48.27 ± 12.8 cc and a mean urethral length of 40.53 ± 9.16 mm. Surgeries were usually performed under local anesthesia. The rates of catheter-free status and complications were 85.2% and 30.83%, respectively. The primary complications included urinary tract infections (17.2%), followed by calcifications (12.6%), irritative symptoms (12.2%), and acute urinary retention (10.4%). During a follow-up period of 12 months, the failure rate intended as stent removal or repositioning was 14.8%. The International Prostate Symptom Score (IPSS) showed an overall improvement of 9.85 points. The mean improvement in maximum flow rate and post-void residual volume were 6.62 ml/sec and 147 ml, respectively.
Conclusions: Prostatic stents remain an efficient choice for addressing obstructive symptoms from BPH, offering the advantage of being performed under local anaesthesia, relieving symptoms with good functional outcomes and a low incidence of major complications. Prospective studies are needed to corroborate these results.

Prostate Cancer and Prostatic Diseases covers all aspects of prostatic diseases, in particular prostate cancer, the subject of intensive basic and clinical research world-wide. The journal also reports on exciting new developments being made in diagnosis, surgery, radiotherapy, drug discovery and medical management.
Prostate Cancer and Prostatic Diseases is of interest to surgeons, oncologists and clinicians treating patients and to those involved in research into diseases of the prostate. The journal covers the three main areas - prostate cancer, male LUTS and prostatitis.
Prostate Cancer and Prostatic Diseases publishes original research articles, reviews, topical comment and critical appraisals of scientific meetings and the latest books. The journal also contains a calendar of forthcoming scientific meetings. The Editors and a distinguished Editorial Board ensure that submitted articles receive fast and efficient attention and are refereed to the highest possible scientific standard. A fast track system is available for topical articles of particular significance.
