A systematic review of holmium laser prostatectomy for benign prostatic hyperplasia.

PURPOSE: We undertook a systematic review to assess the safety and efficacy of holmium laser prostatectomy compared to transurethral resection of the prostate.
MATERIALS AND METHODS: We searched literature databases through August 2002. Holmium laser studies, including holmium laser resection of the prostate (HoLRP) and holmium laser enucleation of the prostate (HoLEP), of any design, and the transurethral prostatectomy (TURP) arms of randomized controlled trials (RCTs) with sample sizes greater than 50 patients, date restricted to 1995 onward, were included for comparison.
RESULTS: Three RCTs comparing HoLRP and TURP, and 2 RCTs comparing HoLEP and TURP were identified. For each of the holmium procedures there was also 1 nonrandomized comparative study and a number of case series (HoLRP 13, HoLEP 10). With the exception of 1 randomized trial the quality of the available evidence was poor, with the other RCTs lacking information regarding methods of randomization, allocation concealment and blinding. The majority of studies were characterized by relatively short followup periods and significant losses to followup. In terms of safety the data suggest that the holmium laser procedures are superior to TURP with regard to a number of key indicators of blood loss (transfusion rates, postoperative bladder irrigation, duration of catheterization and length of hospital stay), although amount of blood loss was rarely reported. In terms of efficacy the holmium laser procedures appear to be similarly effective to TURP in relieving the symptoms of benign prostatic hyperplasia.
CONCLUSIONS: Holmium laser prostatectomy is at least as effective as TURP for managing the symptoms of benign prostatic hyperplasia. However, at the present time the long-term durability of the holmium procedures with respect to TURP cannot be determined due to a lack of published studies with sufficient followup.
