Background: We examined the efficiency and cost effectiveness of a temperature feedback diode-laser system in the treatment of benign prostatic hypertrophy (BPH). Methods: One hundred twenty patients with symptomatic BPH were included in this study between October 1997 and January 1998. Sixty of them were treated by transurethral resection of the prostate (TUR-P), and 60 patients were treated by temperature feedback interstitial laser coagulation (ILC). Direct and indirect cost parameters, such as operative time, operation-related consumables, duration of hospitalization, and amount of medication used were compared between the 2 groups. Results: All subjective and objective urinary parameters exhibited significant improvement 12 months after ILC. A reduction of 26.8% (46.6 to 34.1 ml) of the pretreatment prostate volume was observed at 12 months following ILC. The duration of hospital stay, operative time, and postoperative medications were significantly lower for those receiving. ILC (5.9 to 2.5 days, p<0.001) than for those who underwent TUR-P. The variety of laboratory tests needed for preoperative evaluation was no less when ILC was chosen for treating BPH (p = 0.849). Indirect costs, such as investment in laser equipment and laser accessories were higher in the ILC group (p<0.001). Conclusion: The low morbidity profile, particularly the absence of retrograde ejaculation, makes ILC a valuable and attractive option for treatment of BPH patients who wish to retain their ejaculation ability, who have serious underlying diseases, or who have surgical risks for TUR-P or other invasive modalities.
