A total of 21 consecutive patients with retention of urine underwent visual laser ablation of prostate. Twelve of these had spinal anesthesia, eight had local anesthesia and one had general anesthesia. Seventeen had acute retention; 13 from BPH, 1 due to carcinoma of prostate and three were due to Bladder Neck Stenosis (BNS). Four had chronic retention; three due to BPH and one due to BNS. A Nd:YAG/KTP laser was used and the laser was delivered via Angle Delivery Device. All 13 patients in acute retention due to BPH became catheter free after a mean catheter time of 8 days (range 1 - 22 days), the three patients with acute retention due to BNS were catheter free the next day after the laser incision of the BNS and the patient with acute retention from carcinoma of prostate required a TURP after 45 days of initial laser irradiation. Of the four patients with chronic retention, three with BPH required a TURP procedure after waiting over a month. The patient with chronic retention with BNS was catheter free after 7 days of his laser procedure. We conclude that laser prostatectomy using a side firing laser probe is effective in patients with acute retention but did not work well in our hands for chronic retention patients.
