Prostatic capsular perforation with extravasation resulting in pubic osteomyelitis: a rare complication of KTP laser prostatectomy.

The use of lasers for management of benign prostatic hyperplasia has evolved greatly over the last several years. The 120-W potassium-titanyl-phosphate laser, introduced in 2006 as the GreenLight HPS, boasts a 50% improvement in power over the 80-W laser with theoretical benefit of greater vaporization ability and decreased surgery times. Because of higher energy applied to the tissue, there is also a theoretical risk of increased complications related to capsular perforation or injury to adjacent organs. We report a case involving perforation of the anterior prostatic capsule leading to extravasation and osteomyelitis of the pubic bone.
