[Photoselective vaporization with high-performance potassium-titanil-phosphate laser in the treatment of obstructive...

Novel laser technologies were used in development of a new highly effective and simple method of laser adenomectomy (LA) called photoselective vaporization of the prostate (PVP). The method employs powerful radiation from the laser on the base of potassium titanil-phosphate crystal. Laser radiation was delivered transurethrally by means of a light guide with lateral luminescence. The light guide is installed in a small-diameter channel of the cystoscope and conducts rapid vaporization of adenomic tissues in good hemostasis. Numerous international investigations showed that this method does not provoke hemorrhages, shortens drainage of the urinary bladder with urethral catheter or cathetarization can be avoided, duration of post-operative rehabilitation of the patients, is safe in terms of complications. Efficacy of PVP is comparable to transurethral resection (TUR) of prostatic adenoma but is more cost-effective than TUR or other low-invasive techniques. PVP is safe in patients with concomitant diseases and abnormal coagulation (hemophilia, anticoagulant therapy). Therefore, PVP is very promising in surgical treatment of obstructive prostatic adenoma and may become a leading surgical method in this disease.
