Analysis of complications of transurethral resection of the prostate and transurethral electrovaporization of the prostate

Objective To analyze the common complications during and after transurethral resection of the prostate (TURP) and transurethral electrovaporization of the prostate (TVP) ,and to further improve the efficacy and safety of these procedures. Methods Retrospective analysis was performed in 4156 cases of transurethral prostatectomy, including 1056 cases of TURP and 3100 cases of TVP. Intraoperative, early and late postoperative complications of the 2 groups were analyzed. Results For TURP and TVP groups, the mean operative time was 62 min and 54 min, respectively; the mean resected tissue was 21. 2 g and 36. 7 g; blood transfusion was needed in 14. 1% and 0. 2% of the cases. Transurethral resection syndrome (TURS) occurred in 2. 7% and 0. 9% , urine extravasation in 3. 7% and 0. 8% .postoperative bleeding in 2. 2% and 0. 2% .urinary tract infections in 4. 0% and 5.7% .urethral stricture in 2. 5% and 2. 8% .bladder neck contracture in 2.2% and 2. 1% .erectile dysfunction (ED) in 7.0% and 2.3% .retrograde ejaculation in 45.0% and 45. 6% of the cases,respectively;and permanent urinary incontinence in 1 case of each group. Conclusions Both TURP and TVP are safe and effective surgical treatment for symptomatic benign prostatic hyperplasia. The incidence rates of intra- and post-operative bleeding, TURS, extravasation, ED of TURP are significantly higher than those of TVP;while the rates of urethral stricture and voiding stimulating symptoms of TVP are slightly higher than those of TURP.
