Effectiveness of Transurethral Plasma Kinetic Enucleation of Prostate for Benign Prostatic Hyperplasia Larger Than 60 ml / 中国微创外科杂志

ABSTRACT

Objective To evaluate the short-term safety and efficacy of transurethral plasma kinetic enucleation of the prostate (PKEP)for benign prostatic hyperplasia (BPH)larger than 60 ml. Methods A retrospective analysis was carried out on clinical data and treatment outcomes of 87 cases of BPH with prostate volume larger than 60 ml in Fuzhou General Hospital of Nanjing Military Command from September 2013 to August 2015.The patients were divided into either PKEP group (45 cases)or plasma kinetic resection of prostate (PKRP)group (42 cases).The operation time,resected adenoma weight,decline in hemoglobin 1 day after operation,and catheterization and irrigation duration were recorded and analyzed.The international prostate symptom score (IPSS), quality of life score (QOL),post-void residual urine volume (PVR),maximum urinary flow rate (Qmax)before surgery and 1 ,3,6 months after operation respectively were evaluated. Results As compared with the PKRP group,the PKEP group excelled in greater resected prostate weight [(52.4 ±15.2)g vs.(40.0 ±14.1 )g,t =3.94,P =0.00],less decline in hemoglobin [(9 ±4)g /L vs. (17 ±6)g /L,t =-7.36,P =0.00],shorter irrigation duration [(1 .1 ±0.3)d vs.(1.4 ±0.5)d,t =-3.42,P =0.00],and shorter catheterization duration [(3.3 ±0.5)d vs.(5.5 ±0.5 )d,t =-20.50,P =0.00].There were no significant differences between the two groups in terms of operation time and operative complications such as transient incontinence and hematuria (P >0.05).Postoperative improvements in IPSS,QOL,PVR,and Qmax were similar between the two groups (P >0.05)but significantly improved as compared with before operation (P <0.05). Conclusion PKEP is a new,safe,and effective minimal invasive surgical option for the treatment of BPH larger than 60 ml.
