The Memotherm prostatic stent showed limited success, with only 15 of 48 patients achieving satisfactory results. Further investigation and modifications are needed before permanent prostatic stents are widely adopted.

Area of Science:

  • Urology
  • Medical Devices
  • Prosthetic Surgery

Background:

  • Benign prostatic hyperplasia (BPH) causes bladder outflow obstruction.
  • Prostatic stents offer a minimally invasive treatment option for BPH.
  • The Memotherm stent is a permanently implantable option for managing BPH.

Purpose of the Study:

  • To evaluate the efficacy and safety of the Memotherm permanently implantable prostatic stent.
  • To assess patient outcomes following Memotherm stent implantation for bladder outflow obstruction.

Main Methods:

  • A prospective study involving 48 men with symptomatic bladder outflow obstruction.
  • Memotherm stents were implanted into the prostatic urethra.
  • Follow-up included subjective and objective assessments at 1, 3, and 6 months.

Main Results:

  • 10 stents were removed, and 3 patients awaited removal; 47 patients could eventually void.
  • Subjective patient improvement did not correlate with objective measures like maximum urinary flow rate.
  • Only 15 out of 48 patients reported a satisfactory outcome.

Conclusions:

  • Permanently implanted prostatic stents, including the Memotherm, require further intensive investigation.
  • The Memotherm stent design necessitates significant modifications based on study findings.
  • Current evidence suggests a cautious approach to the widespread clinical adoption of permanently implanted prostatic stents.
