INTRAPROSTATIC METAL STENTS (PROSTAKATH(R) AND UROSPIRAL(R)) - MORE THAN 6 YEARS CLINICAL-EXPERIENCE WITH 110 PATIENTS

We reviewed the long-term results of two different intraprostatic meta l stents. Patients (N = 110) with either benign prostatic hyperplasia or prostatic cancer were included in a prospective study and treated b y the insertion of one of two intraprostatic stents (Prostakath(R) or Urospiral(R)), The mean follow-up was 53 (range 36-80) months, Subject ive and objective symptoms and signs were evaluated at each follow-up visit. The different complications and overall success rates were comp ared for the two intraurethral spirals, When considering both patient satisfaction and device functionality, the overall success rate was 65 %, Stent migration, incrustation, failure to void, and clinical infect ions were the most common complications, Of 41 cases of late complicat ions, removal of the stents was required in 35 patients, No difference in the rate of late complications was noted for the two stents. Intra urethral stents are well-tolerated by patients, The relatively low cos t of spirals and the fact that they may be left in situ for long perio ds' renders them highly cost efficient, There is a need for continued close follow-up when the stent is left in situ for prolonged periods, There was no significant difference between the two metal stents despi te their different coating.
