COMPARATIVE STUDY BETWEEN ELECTROVAPORIZATION AND TRANSURETHRAL RESECTION FOR TREATMENT OF BENIGN PROSTATIC HYPERPLASIA

Abstract

The ultimate role of various alternative methods of performing TURP remains to be determined. Electrovaporiz.ation is a modified electrosurgical modality that is quickly gaining popularity. However, long-term efficacy and safety data have yet to mature and determine whether TUEVP will be a durable long-term modality in the treatment of lower urinary tract symptoms.

To compare efficacy, safety, and durability of transurethral electrovaporiz.ation of the prostate (TUEVP) with standard TURP. This randomized prospective study was performed, Which included 124 consecutive men, with symptomatic benign prostatic hyperplasia (BPH), admitted for surgery. They were randomized to either, TUEVP or TURP. Sixty-two patients underwent TURP with a mean age of 60.2 years, and 62 patients underwent TUEVP, having a mean age 62 years. There was no significant difference between any variable at baseline between the two groups.

The variables evaluated included, the international prostate symptom score (IPSS), a quality of life assessment index (QOL), peak urinary flow rate (Omax), and post-void residual urine volume (PVR). As well as duration of surgery, catheterization and hospital stay were also compared. Changes in serum levels• of hemoglobin, hematocrit, sodium and potassium were assessed hour and day postoperatively. Sexual function was also evaluated during follow-up at 1, 3, 6, 12, and 18 months. Patients were seen in. A total of 95 patients were available for follow up at l 8months.

Both methods improved symptoms and objective indicators of urinary obstruction. The mean IPSS decreased from 24 to 4.6 (TURP) and from 22 to 5.5 for (TUEVP). The mean Qmax increased from 8.3 to 18.8 ml /sec. (TURP) and from 7.8 to 17 ml /sec for the TUEVP. PVR decreased from 126 ml to 31 (TURP) and from l 08 to 28 ml (TUEVP) at 18 months follow-up.
