[Comparative study of transurethral electrovaporization of prostate versus transurethral resection of prostate on benign prostatic hyperplasia].
OBJECTIVE
To compare the efficacy of transurethral electrovaporization of prostate (TUVP) with transurethral resection of prostate (TURP).


METHODS
206 patients with symptomatic benign prostatic hyperplasia (BPH) whose prostatic sizes were all less than 60 grams were randomly divided into two groups. 97 cases were treated by TUVP while the other 109 cases were treated by TURP. The patients who underwent either TUVP or TURP were followed up for 12-34 months with an average of 20 months postoperatively.


RESULTS
Both groups showed the significant decline in the mean IPSS (international prostatic symptom score) (P < 0.01), the mean PVR (Postovoiding Residual Volume) (P < 0.01), while increase in mean Qmax (Peak uroflow rate) (P < 0.01) in 12 months, 24 months after the operation. There were significant differences in the mean duration of operation or catheterization postoperatively (P < 0.05). The main complications of post-operation in the two groups were stress incontinence, TUR syndrome, urethral stricture, secondary bleeding.


CONCLUSIONS
Both TUVP and TURP are effective treatment for the patient with BPH whose prostatic size is less than 60 grams. TUVP spends shorter time of the operation and postoperative catheterization than that of TURP.
