A simple method for insertion of an intraprostatic coil.

A simplified method of insertion of a urethral coil for treatment of benign prostatic obstruction has been tested in 25 patients. The prostatic urethra is measured either by abdominal/transrectal ultrasound scanning or by rigid or flexible endoscopy. The coil is inserted into the prostatic urethra using simple measurements taken from a Foley catheter; 21 coils were correctly positioned at the first attempt using this new method--a success rate equivalent to that of ultrasound-guided insertion.
