[Long-term results of prostatic photoselective vaporization in the treatment of prostatic adenoma]

Assessment of long-term efficacy and complications of prostatic photoselective vaporization (Green Light PV (tm) device, Laserscope, 80W; laser cystoscope, Olympus) was performed in 40 patients with prostatic adenoma (PA) treated in 2005-2006. Mean follow-up was 30.6 +/- 16.6 (5.2-60.6) months, time of operation--52.4 min, intraoperative blood loss--52 ml maximum, duration of bladder draining with catheter--1.15 days. For 12 postoperative months IPSS and QoL declined, then for up to 60 months these parameters went up. An 11-month postoperative follow-up recorded a 68.6% maximal decrease in prostatic volume (the size of the prostate decreased to 22.6 cm3), but after 4 years this volume increased by 24.6% to 38.8 cm3. Qmax increased more actively during postoperative year 1 and reached maximal value to postoperative month 36. Residual urinary volume fell to initial 95.7 ml to minimal 24.8 ml on follow-up month 12. Mean quantity of energy reached 206 +/- 94 (2.4-619.0 kJ. Eleven patients had to take oral anticoagulants without any serious intra- or postoperative complications. Recurrent adenoma rose in 4 patients, urethral stricture--in 6.8% patients, cervical bladder sclerosis was found in 3.6% cases. Prostatic cancer development was not registered. Thus, prostatic photoselective vaporization is a safe and efficave procedure in PA treatment.
