Abstract
Recently great interest has been generated in alternatives to transurethral resection for benign prostatic hyperplasia. Lasers are currently being assessed, but marketing has for the moment outstripped basic science. A cystoscopic approach was used delivering Nd:YAG or KTP laser energy via forward and sidefiring fibers and contact tip devices in 51 patients. The sidefiring device is intended to coagulate a volume of prostate that subsequently sloughs, leaving a cavity. Treatment of the apical and middle lobe tissue using this technique was unsatisfactory. A further disadvantage was the interval between treatment and improvement in urine flow, which was approximately 6 weeks. The use of temporary prostatic stents has helped to overcome this delay in treatment effect. Encouraging early results have been achieved using forward-firing fibers to treat apical and middle lobe tissue. The use of contact tip devices to perform bloodless prostatotomies in combination with sidefire or bare fiber has also proved useful. Laser prostatectomy is an exciting field with considerable potential but remains in the developmental stage.
