Kim M, et al. - Researchers gauged the impact of urodynamic detrusor overactivity (DO) on the outcomes of transurethral surgery in patients with male bladder outlet obstruction (BOO). The PubMed, Embase, and Cochrane Library databases were systematically searched for articles published between January 1989 and June 2017. Findings did not suggest any diagnostic role of preoperative urodynamic in the prediction of surgical outcomes in patients with male BOO.
