Short-term study of robot-assisted laparoscopic simple prostatectomy

Abstract

Objective To assess the feasibility and efficacy of robot-assisted laparoscopic simple prostatectomy (RALSP) for the treatment of benign prostatic hyperplasia (BPH) with large prostate. Methods From January 2014 to July 2015, 16 patients with large prostate (≥80 ml) were treated by RALSP. The average patient's age was 69 years. The prostate volume was (98.3±12.9) ml, preoperative residual urine was (78.0±24.8) ml, the average IPSS was (22.9±5.9), the average QOL was (4.8±1.5) and the average Qmax was (8.9±3.7) ml/s, respectively. All patients agreed to accept RASP. The pre-operative and three months post-operative IPSS, QOL, residual urine and Qmax were compared and analyzed. Results All 16 patients underwent the surgeries uneventfully. The average operation time was (92.5±15.5) minutes, the estimated blood loss was (125.5±25.5) ml, drainage time was (4.6±0.8) days, catheterization time was (7.9±1.2) days and postoperative hospital stay was (5.1±1.1) days. Three months after surgery, patient's IPSS was (11.8±3.1), QOL was (1.6±0.9), the average residual urine was (12.3±2.6) ml and Qmax was (29.4±11.6) ml/s, respectively. All the parameters significantly improved compared with the preoperative data (P<0.05). Conclusions Robot-assisted laparoscopic simple prostatectomy is a safe and effective method for the treatment of BPH patients with prostate volume larger than 80 ml.
