Objective To analyze the causes and managents of readmission after transurethral vaporesection for benign prostatic hyperplasia by 2μm continuous wave laser. Methods A retrospective study was conducted to summarize the cases who were readmitted after transurethral vaporesection for BPH by 2μm continuous wave laser. Results 317 patients received this operation from June 2011 to June 2014 in our hospital. Among them, 16 patients experienced readmission after mean interval of 1.8 months with an incidence rate of 5.05%. 8 cases that had experienced bleeding and acute retention underwent transurethral bladder washing and coagulating. Bladder neck contracture was found in 3 cases and received transurethral resection of scar by 2μm continuous wave laser, followed with regular urethral dilatation. Prostate cancer was detected in 2 cases, who received medical castration finally. 1 cases developed anterior urethral stricture and received internal urethrotomy by 2μm continuous wave laser and followed with regular urethral dilatation. 2 case received antibiotic therapy for urological tract infection or unilateral acute epididymitis. Conclusions Bleeding and bladder neck contracture were main causes for readmission after this operation. Correct preoperative diagnosis, rational surgical type and adequate intraoperative and postoperative management are keys to preventing readmission.
