[Observation and preventative strategies of complications in transurethral electrovaporization of the prostate: report of 920 cases].

OBJECTIVE: To investigate the post-operative complications and preventative strategies of them in transurethral electrovaporization of the prostate(TVP). METHODS: Nine hundred and twenty patients with symptomatic benign prostatic hyperplasia (BPH) were treated by TVP. RESULTS: Post-operative complications included severe Hemorrhage in 30 cases (3.3%), transurethral resection syndrome (TURS) in 6 cases (0.7%), acute lower urinary tract infection in 16 cases (1.7), acute epididymitis in 11 cases (1.2%), acute urinary retention in 34 cases (3.7%), incontinence in 35 cases (3.8%), urethral stricture in 26 cases (2.8%), recurrence in 22 cases (2.4%). There were retrograde ejaculation in 54.5% (24/44) and impotence in 9.1% (4/44). CONCLUSION: Although TVP is more effective than standard TURP in the treatment of lower urinary tract symptoms caused by BPH, complications during TVP procedures require special consideration.
