Clinical observation of bipolar plasmakinetic resection of prostate and transurethral resection of prostate in treatment of large-size benign prostate hyperplasia

【Objective】To evaluate the safety and efficacy of bipolar plasmakinetic resection of prostate (PKRP) in treatment of large-size benign prostatic hyperplasia (BPH), and compare it to the standard transurethral resection of prostate (TURP). 【Methods】119 cases with large-size BPH treated with PKRP or TURP were retrospectively analyzed. Those patients were under the age of 55~83 years, with a maximum urinary flow rate (Qmax) of 0~10.6 mL/s, an International Prostate Symptom Score (IPSS) of 20~33 and prostate volume of 71 to 231 mL. The general data of the two groups were comparable. 【Results】There were no significant difference between the two groups in the operation duration, catheterization period and hospital stay (P 0.05). The IPSS decreased significantly, while Qmax increased significantly in both groups in 3 months after the operation(P 0.05). But there were no difference in IPSS and Qmax between them postoperatively (P 0.05). The bleeding in PKRP group was less than that in TURP group(P 0.05). The complications such as blood transfusion and transurethral resection syndrome (TURS) in PKRP group were less than those in TURP group. With 3 months to 52 months (mean 31 months) follow-up, all of the patientsobtained stable urination. 【Conclusion】Both PKRP and TURP are safe and effective for large -size BPH with skilled transurethral resection technique. PKRP has fewer complications, with advantages of good hemostasis, exquisite resection, less effect on the physiologic function, therefore it is more safe than traditional TURP for the treatment of large-size BPH.
