• Prostatic obstruction;
  • temporary coil;
  • stent

Objective To determine the benefits of a new selfexpanding and self-retaining large calibre temporary intraprostatic coil stent in patients with bladder outflow obstruction due to benign prostatic hypertrophy.

Patients and methods Sixty-five patients with bladder outflow obstruction have been studied with a followup period of 3–28 months (mean 16).

Results Thirty patients became eligible for surgery and had their stent removed without difficulty 3–12 months after stent insertion. Only one stent was removed because of urgency and incontinence. Stent repositioning was required in five patients and 14 complained of temporary dysuria or perineal pain. Twenty-seven patients continue to pass urine through their stent without difficulty.

Conclusion Because of its large diameter and its temporary nature this new stent allows endoscopic examination of the bladder and has few side effects. This stent should be considered as an alternative to a urethral catheter or other temporary stents in patients who are unfit for surgery.
