Background: The therapeutic modalities in the management of benign prostatic hyperplasia have changed dramatically over the past 10 years. We, therefore, investigated therapeutic results of several types of treatment options.
Materials and Methods: From February 1993 to August 1997. the results of transurethral resection of prostate(TURP: 57 patients), transurethral electrovaporization of prostate(TUEP: 21 patients), transurethral microwave thermotherapy{TUMT: 28 patients) and medication(52 patients) were analyzed. Efficacy parameters evaluated included symptom score, urinary flow rate, postvoid residual urine and complications.
Results: The symptomatic improvement was 82.5% in the TURP group, 80% in the TUEP group, 65.0% in the TUMT group and 71.4% in the medication group. There were statistically significant improvements in symptom score for TURP, TUEP and medication groups. The improvement in the maximal flow rate was 84.2% in the TURP group, 66.7% in the TUEP group, 50% in the TUMT group and 41.7% in the medication group. There were statistically significant improvements in flow rate for TURP and TUEP groups. The improvement in postvoid residual urine was 88.2% in the TURP group, 64.3% in the TUEP group, 53.9% in the TUMT group and 56.0% in the medication group. There were statistically significant improvements in postvoid residual urine for TURP and TUEP groups. The incidence of complications were 8 in 57(14%) in the TURP group and 2 in 21(9.5%) in the TUEP group. In TUMT group, no noticeable complications were observed. The adverse reactions were mild and transient in the medication group.
Conclusions: The results of TURP and TUEP compared to those of TUMT and medication group were exellent. With these results, we can conclude that TURP is the most effective treatment method of the four treatment options for symptomatic BPH. TUEP is recommended as an alternative for patients with a small prostate. Medication delivers symptomatic improvements with mild adverse reactions. One session of TUMT seems to have insignificant therapeutic effect on BPH patients.
