Comparison of the clinical effectiveness of transurethral resection of the prostate and transurethral vaporization-resection of the prostate / 中华泌尿外科杂志

ABSTRACT

Objective To compare the efficacy and complications between transurethral resec-tion of the prostate(TURP) and transurethral vaporization-resection of the prostate (TUVRP). Methods 637 cases of benign prostatic hyperplasia(BPH)were divided into 2 groups, 298 cases un-derwent TURP and 339 underwent TUVRP. The maximal flow rates (Qmax) were (9.8±2.3)ml/s, (10.1±2.1) ml/s, the international prostatic symptom scores (IPSS) were 15.3±3.1,15.1±3.7 re-spectively. The surgical outcomes and the complications of the 2 groups were analyzed. Results For the TURP group and TUVRP group, the postoperative Qmax were (19.0±2.9)ml/s and (18.0±2.3) ml/s, both significantly higher than those of preoperation(P<0.01). There was no significant differ-ence between the 2 groups(P0.05). For the TURP group, the mean operation time was (52±16) rain, visual hematuria lasting for (9.0±2.3) d, secondary bleeding in 6 cases (2.0%), lower urinary tract infection in 14 cases(4.7%), 1 month after operation lower urinary tract symptom(LUTS) in 26 case(8.7%), IPSS was 5.0±1.4, contemporary incontinence in 6 cases(2.0%), memberanous sticture 4 cases(1.3%). For the TUVRP group, the mean operation time was (68%19)min, visual hematuria lasting for (12.0±3.6) d, secondary bleeding in 19 cases (5.6%), lower urinary tract infection in 38 cases(11.2%) ,1 month after operation LUTS in 59 cases(17.4%) ,IPSS was 8.0±1.6,contemporary incontinence in 13 cases(3.8%), memberanous stieture in 16 cases (4.7%). There were significant differences between the 2 groups. For the TURP group, blood loss during operation was (126±29) ml, resected tissue weighed (31±8)g, pre- and post-operative serum natium consentration balance was (8±6)mmol/L,TURS developed in 3 cases(1%). For the TUVRP group, blood loss during opera-tion was (122±38)ml, resected tissue weighed (33±9)g,pre- and post-operative serum natium con-sentration balance was (7±7) mmol/L, TURS developed in 2 cases(0.6%). There was no significant differences(P0.05). Conclusions TURP and TUVRP have similar efficacy treating symptomatic BPH. The incidences of complications of TUVRP are slightly higher than those of TURP.
