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.

Intragastric balloon as an artificial bezoar for treatment of obesity.

A free-floating rubber balloon was installed as an artificial intragastric bezoar in five obese women. These patients were studied for a total of 272 days - i.e., 130 days with the balloon inflated (10 periods) and 142 days when the balloon was known to be deflated (7 periods). The balloons were easy to insert and reduced hunger. They remained inflated for 7 to 21 days (median 12 days) as judged by radioscopy. Collapsed balloons passed unnoticed with the stools. There were no complications associated with their use. During consecutive periods with balloon, without balloon, and with balloon average weight-losses over 10 days were: 5.0 kg (range 8.6 to 2.0), 0.5 kg (2.9 to 0.3), and 2.1 kg (2.6 to 1.2), respectively. The weight-loss observed while the balloons were inflated is promising but the efficacy of the method can only be evaluated when balloons which remain inflated for several months within the stomach become available.
