Abstract:【Objective】 To investigate the clinical effect and safety of four quadrants enucleation of prostate over pubis with cystostomy in the treatment of benign prostatic hyperplasia (BPH). 【Methods】 From June 2011 to June 2013, 212 BPH patients were divided into test group(119 patients), treated with four quadrants enucleation of prostate over pubis with cystostomy and control group (93 patients), treated with conventional enucleation of prostate. The time of operation, blood loss in operation, catheter indwelling time, days in hospital after operation, washing time, washing fluid amount, hospitalization expenses and situation of IPSS, QOL, Qmax (mL/s), PVR (mL) and urethrostenosis, urinary incontinence complications in 6 months' follow-up were compared between the two groups. 【Results】 By comparison, the time of operation, blood loss in operation, catheter indwelling time, days in hospital after operation, washing time, washing fluid amount and hospitalization expenses in the test group were better than the control group. The difference was statistically significant (P<0.05); The situation of IPSS, QOL, Qmax (mL/s), PVR(mL) of the two groups in 6 months' follow-up had no statistically significant difference (P>0.05); The occurrence rate of urethrostenosis, urinary incontinence complications in two groups in 6 months' follow-up, the difference was not statistically significant (P>0.05). 【Conclusion】 Four quadrants enucleation of prostate over pubis with cystostomy is safe, effective, time controllable and clinical applicable.
