OBJECTIVES: The aim of this study was to evaluate efficacy and safety of transurethral evaporation of the prostate (TUEP) using neodymium:yttrium-aluminum-garnet (Nd:YAG) laser in prostate glands of various sizes.
METHODS: One hundred consecutive patients with benign prostatic hyperplasia (BPH) and prostate volumes less than 40 cc (group I, n = 41), 41 to 80 cc (group II, n = 39), and more than 80 cc (group III, n = 20), who had preoperative prostate volume estimation by transrectal ultrasound and had completed a minimum of 3 months' follow-up, underwent TUEP. At baseline, and at 3 and 6 months, American Urological Association (AUA) score, peak flow rate (PFR), postvoid residual urine (PVR), and complications, if any, were documented.
RESULTS: There were no significant differences in failure rates, complications, or ability to improve symptom score, PFR, and PVR between patients with prostate glands of various sizes. The mean improvement in PFR at 6 months was: group I, 9.9 cc/s (116%); group II, 7.4 cc/s (81%); and group III, 9.2 cc/s (107%). Reduction in AUA score was: group I, 14.6 (63%); group II, 17.7 (71%); and group III, 16.2 (70%). PVR was: group I, 62.5 cc (51%); group II, 31.4 cc (16%), and group III, 71 cc (83%) (differences not significant). The patients in urinary retention were separately analyzed (group I, 9, group II, 12, and group III, 5) and mean PFR at 6 months was: group I, 18.5 cc/s, group II, 15 cc/s, and group III, 17.1 cc/s. Mean AUA score at 6 months was: group I, 25.8; group II, 21; and group III, 23.6. Mean PVR score was: group I, 370 cc, group II, 439 cc; and group III, 400 cc (differences not significant). Mean postoperative catheterization time was higher in patients with glands larger than 80 cc (2.2 versus 2.9 versus 4.7 days in groups I, II, and III, respectively, P < 0.009 between groups II and III). Incidence of urinary tract infection (10 versus 0%) was greater in patients receiving only 48-hour as opposed to 10-day postoperative antibiotics.
CONCLUSIONS: TUEP appears to be a safe and effective treatment for relief of symptoms of BPH and improvement of PFR in patients with all sizes of prostate glands.
