Lee, Young Keun; Lee, Min Sung

Abstract

Prospective study to evaluate the results after 2 year`s follow-up was done in 16 patients with prostatic infravesical obstruction treated by insertion of an intraprostatic stent: In eight patients, removal of the stent or cystostomy without removal of it was performed due to urinary retention. severe vesical irritability and local penile discomfort, etc. Five patients were able to void satisfactorily and the remaining three patients managed to live with some voiding problems. Stone formation was found in 10 or 16 consecutive patients and mild displacement of the stent proximally was in 2 patients. Of the 8 patients with a functioning stent, hematuria in 7 patients, pyuria in 6 patients and positive urine culture in 3 patients were noted. Our experience suggests that stone formation and recurrent urinary infection are serious complications in long-term indwelling of the stent.
