Feasibility and safety of prostatic vaporization using 180W greenlight system in day surgery mode

Abstract

Objective To evaluate the feasibility and safety of 180W greenlight laser in the treatment of benign prostatic hyperplasia (BPH) in the day surgery mode. Methods A retrospective review included 65 patients with benign prostate hyperplasia who were treated with photoselective vaporization of the prostate (PVP) under 180W greenlight system from Jan 2017 to Jan 2018, was performed. The patients’ age ranged from 54 to 75 years old and the prostatic volume ranged from 42 to 93 ml. All patients were classified into two groups [day sugery group(n=29) and inpatient surgery group(n=36)] based on the wishes of patients. In day sugery group, the admission, operation and discharge were completed in 24 hours. The preoperative clinic parameters such as prostate volume, IPSS, Qmax, QOL and PVR were recorded in the two groups. The prostatic volume in two groups was (67.3±15.9) ml and (70.4±16.1) ml, respectively. The IPSS and QOL scores in two groups were (23.2±4.6 vs. 23.9±4.5) and (4.7±0.9 vs. 4.4±0.8), respectively. The Qmax and PVR in two groups were [(6.7±2.5)ml/s vs. (6.8±2.8)ml/s] and [(133.9±81.3)ml vs.(105.8±76.3)ml], respectively.The time of catheterization and postoperative hospitalization, total cost, postoperative adverse events were recorded, too. All the clinic data of preoperation, intraoperation and postoperation were compared between two groups. Results The operations and follow-up were successfully executed in all patients. There were not statistical significance differences in preoperative parameters between the two groups (P>0.05). There were not statistical significance differences in operating time [(67.8±9.8) min vs.(70.9±12.8) min], laser time [(49.8±8.3) min vs.(51.6±10.4) min], energy used [(295.7±112.6) kJ vs.(285.0±108.2) kJ], between the two groups, too (P>0.05). A significantly less mean catheter duration, hospital stay and hospital charges were observed in the day surgery group [(14.6±2.0)hours, (0.5±0) days and (23 279±511) yuan, respectively] than in the inpatient surgery group [(51.7±11.8) hours, (3.0±0.8) days and (27 452±440)yuan, respectively, P 0.05). However, significant difference of those items could be noticed when compared with those items before surgery(P<0.05). Conclusions In the day surgery mode, 180W greenlight laser vaporization of the prostate is safe and effective, without the increase of surgical complications. The length of stay and hospitalization expenses were much less. Thus, this strategy is worth promoting in clinical practice.
