Objective:To explore the application of 16-words formula " resection surrounding the proximal part of seminal colliculus, lateral tunnel, plane extending and bladder neck preservation" in transurethral enucleation resection of prostate with plasma rod electrode (TUERP).Methods:The clinical data of 88 patients with benign prostatic hyperplasia (BPH) admitted to our department from May 2018 to July 2019 were retrospectively analyzed. The age of patients was (67.0±8.6)years, and the volume of prostate was (51.0±27.3)ml. All patients were treated with TUERP using transurethral plasma rod electrodes according to the above 16-words formula. The perioperative clinical data and follow-up results at the 3rd month postoperation were statistically analyzed.Results:All operations were successfully completed. The operation time was (49.7±17.7)min, including gland enucleation time (16.8±6.7)min, tissue resection time (33.0±12.3)min, enucleated tissue weight (45.5±24.4)g, intraoperative blood loss (10.2±2.9)ml, postoperative continuous bladder irrigation time (1.9±0.8)d, postoperative hospital stay (4.1±0.7)d. There were no significant changes in hemoglobin and sodium concentration at 2 hours after operation ( P>0.05). The International Prostate Symptom Score (IPSS), quality of life score (QOL), maximum urinary flow rate (MFR) and residual bladder urine were significantly improved at 3 months after operation ( P<0.05). The patients were followed up for 3 to 14 months (average 6.8 months). There were 6 cases of Clavien grade Ⅰ complications, 1 case of Clavien Ⅱ complications, 1 case of Clavien Ⅲ complications, and no Clavien Ⅳ-Ⅴ complications occurred. Conclusions:The TUERP with plasma rod electrode according to the 16-words formula is an ideal choice for BPH treatment, which has the advantages of simple operating, high efficiency of enucleation, less blood loss, fast recovery and satisfied improvement of urination symptom.
