Comparison of transurethral plasmakinetic and transvesical prostatectomy in treatment of 100–149 mL benign prostatic hyperplasia

Abstract

To compare the safety and efficacy of transurethral plasmakinetic resection of the prostate (PKRP) versus transvesical prostatectomy (TVP) in the treatment of large-volume benign prostatic hyperplasia (LV-BPH) (100-149mL). Ninety-nine BPH patients who had a prostate volume of 100-149mL were divided into two groups to undergo PKRP or TVP. Preoperative clinical data were analyzed. Patients had follow-up appointments at 1 month, 3 months, 6 months, and 12 months postoperatively. Outcome measures included the International Prostate Symptom Score, quality of life score, maximum urinary flow rate, and postvoid residual urine volume. Adverse effects were also recorded. A total of 96 patients completed the 12-month follow-up. The operative time was longer, but intraoperative blood loss was lower in the PKRP group. Despite a higher percentage of patients requiring a blood transfusion, there was an obvious advantage in gland removal rate in the TVP group. The duration of postoperative catheterization, bladder irrigation, and hospital stay was significantly shorter in the PKRP group. Outcome measures were significantly improved in both groups 1 month postoperatively. The improvement in lower urinary tract symptoms was maintained throughout the 12 months after surgery. There were no significant differences in International Prostate Symptom Score, quality of life, maximum urinary flow rate, and postvoid residual urine volume between the two groups. PKRP has the advantage over TVP of being minimally invasive in the treatment of LV-BPH while achieving the same postoperative outcomes.
