ABSTRACT

Objective To evaluate the safety of simultaneous transurethral green laser vaporization therapy in benign prostatic hyperplasia (BPH) and nonmuscle-invasive bladder transitional cell carcinoma (NMIBT).Methods The clinical data of 27 patients (observation group) who had undergone simultaneous transurethral green laser vaporization therapy in BPH and NMIBT between May 2004 and October 2010 were analyzed retrospectively.Meanwhile 27 patients(control group) only had undergone green laser vaporization therapy in NMIBT during the same period were selected.Clinicopathologic parameters,rate of recurrence and progression,rate of recurrence in the bladder neck and prostatic urethra were determined and compared.Results The time of follow-up in observation group and control group were (28.61 ± 19.53) and (30.20 ± 21.46) months.The rates of recurrence,progression and recurrence in the bladder neck and prostatic urethra between observation group and control group had no significant differences [ 18.5％ (5/27) vs.25.9％ (7/27),3.7％ (1/27) vs.0,0 vs.0] (P ＞0.05).Conclusion Simultaneous transurethral green laser vaporization of NMIBT and BPH can be safely performed without increasing the risk of tumor recurrence in the prostatic urethra.
