A comparative study of transurethral plasma kinetic resection versus transurethral resection of the prostate for benign prostatic hyperplasia

Objective:To compare the clinical efficacy and safety of transurethral plasma kinetic resection of prostate (PKRP) and transurethral resection of prostate (TURP) for benign prostatic hyperplasia (BPH). Methods:Totally 164 BPH patients with matched lesions were divided into 2 groups: PKRP group and TURP group at our institute. The clinical date and therapeutic results were measured and compared between the 2 groups.Results:In PKRP group, the average operative time, intraoperative bleeding, the rates of postoperative temporary urinary incontinence(within 1 month), secondary hemorrhage (within 1 month) were (60±16)min, (224±78)ml,17.1 %(14/82) and 9.8% (8/82), respectively; while in TURP group, these parameters were(80±21)min, ( 408±115)ml, 31.7 %(26/82) and 18.3% (15/82),respectively. Significant differences were found between the 2 groups (P0.05).Resected prostate weight was 28.6 ±3.6 g in PKRP group versus 26.2 ±3.2g in TURP group. Intraoperative blood transfusion rate was 1.2%(1/82) in PKRP group and 3.6%(3/82) in TURP group. There were 3 pre-transurethral resection syndrome(TURS) patients and 1 TURS patient in TURP group, No transurethral resection syndrome(TURS) occurred in PKRP group. Of all the cases, 72 patients of PKRP and 76 patients of TURP were followed up for 3 months. Three patients in PKRP group and 10 patients in TURP group were found having urethral stricture after 3 months. In PKRP group, Qmax, postvoid residual(PVR) , the International Prostate Symptom Score(IPSS) and quality of life (QOL) were (22.6±4.6)ml/s, (8.6±4.4)ml, (4.6±1.2) scores, (1.2±0.6) scores , respectively; while in TURP group,these parameters were (24.2±4.2)ml/s, (9.6±3.6)ml, (4.4±1.0) scores, (1.4±0.8) scores, respectively, these parameters were significantly improved after both procedures(P0.05), but there was no significant difference in the above parameters between 2 groups (P0.05).Conclusions:PKRP and TURP have similar efficacy in the treatment of BPH, but PKRP is safer and less complicated than TURP. Thus, PKRP is a better treatment option for BPH.
