[Transurethral photoselective laser vaporization in the treatment of prostatic adenoma].
Progress in laser technologies allowed development of a highly effective method of laser adenomectomy--photoselective vaporization of the prostate (PSVP). The method employs highly potent potassium-titanyl-phosphate (KTP) laser. PSVP with KTP laser (80 W) [GreenLight PV (tm), Laserscope] was made in 40 patients. Duration of surgery averaged 52.4 min, mean time of urethral catheter stay was 14 hours. Complications were insignificant (short-time dysurea--12%, hematurea--8%). Control examination of all the patients 1, 3, 6 and 12 months after PSVP has shown that IPSS diminished by 78% and was 5 points, QoL improved by 50% (2.6 points), Qmax increased by 112% (mean 18.3 ml/s, residual urine reduced by 74% (mean 22.1 ml). Thus, PSVP is low-invasive, is accompanied neither with absorption of the lavage fluid nor with blood loss, reduces hospital stay of the patients, can be performed outpatiently or in day hospital. Therefore, PSVP is an alternative to conventional TUR. Further trial of long-term results of PSVP is needed.
