Is there a correlation between the outcome of transurethral resection of prostate and preoperative degree of bladder outlet obstruction?

To compare the impact of transurethral resection of prostate (TURP) on symptom scores and maximal flow rates (Qmax) in patients with equivocal bladder outlet obstruction (BOO) and definite BOO and to assess the relationship between the surgical outcomes and degree of preoperative BOO, we prospectively evaluated men with lower urinary tract symptoms and bladder outlet obstruction index (BOOI) greater than 20, who were refractory to conventional medical treatment and underwent TURP. Urodynamic evaluation, International Prostate Symptom Score (IPSS), uroflowmetry, post-void residual volume (PVR) check and transrectal ultrasound were performed. 20
