The second-generation UroLume prostatic stent showed promise but faced issues with migration and hyperplasia in about a third of patients. Further assessment is needed before widespread use of permanent stents.

Area of Science:

  • Urology
  • Medical Devices

Background:

  • Benign prostatic hyperplasia (BPH) causes bladder outflow obstruction.
  • Transurethral resection is a common treatment, but alternatives are sought.

Purpose of the Study:

  • To evaluate the efficacy of the second-generation UroLume prostatic stent.
  • To assess its performance as an alternative to transurethral resection.

Main Methods:

  • 47 men with symptomatic bladder outflow obstruction received the UroLume stent.
  • Follow-up included voiding, obstructive and irritative scores, and peak flow measurements.

Main Results:

  • Stent insertion was successful in 44 men; all voided spontaneously.
  • After 2 years, 14 stents required removal due to migration or epithelial hyperplasia.

  • Mean obstructive score was 1.6, irritative score 2.5, and peak flow 16.8 mL/s.

    • Conclusions:

    • Epithelial hyperplasia and stent migration occurred in approximately one-third of patients.
    • A third-generation stent has been developed.
    • More extensive studies are required before recommending permanent stents for general use.
