目的评价前列腺指裂术治疗小体积前列腺增生(体积<30 g)致膀胱出口梗阻(BOO)的疗效。方法对36例小体积前列腺增生致 BOO 患者行前列腺指裂术,比较国际前列腺症状评分(IPSS)、最大尿流率(Qmax)及残余尿量(PRV)治疗前后变化,评价该术式疗效。结果所有患者均行前列腺指裂术。IPSS 由术前14.19±5.35降至术后5.03±2.66(P<0.001),Qmax 由术前Qmax(6.19±2.14)ml/s 升至术后(17.71±4.10)ml/s(P<0.001),PRV 由术前(50.58±14.84)ml降至术后(8.53±4.78)ml(P<0.001)。共33例患者获随访,术后随访平均32个月(9～52个月)。结论前列腺指裂术是治疗小体积前列腺增生致膀胱出口梗阻较为理想的方法。
Objective To evaluate the efficacy of prostatic malformation in the treatment of bladder outlet obstruction (BOO) caused by small volume benign prostatic hyperplasia (volume <30 g). Methods 36 prostatic hyperplasia-induced BOO patients underwent prostate dehiscence. The changes of IPSS, PRmax and residual urine volume (PRV) were compared before and after treatment to evaluate the efficacy of the operation. Results All patients underwent prostate dehiscence. IPSS decreased from 14.19 ± 5.35 preoperatively to 5.03 ± 2.66 postoperatively (P <0.001), and Qmax increased from preoperative Qmax (6.19 ± 2.14) ml / s to postoperative postoperative (17.71 ± 4.10) ml / s (P <0.001) PRV decreased from 50.58 ± 14.84 ml to 8.53 ± 4.78 ml after operation (P <0.001). A total of 33 patients were followed up for an average of 32 months (range 9-52 months). Conclusions Prostate finger dissection is an ideal method for the treatment of bladder outlet obstruction caused by small volume benign prostatic hyperplasia.
