Objectives To investigate the correlation of preoperative overactive bladder symptoms and urodynamic parameters to the improvement of overactive bladder symptoms after transurethral resection of the prostate. Methods A retrospective study was carried out in 128 patients with urodynamically proven benign prostatic obstruction that underwent transurethral resection of the prostate. All patients had preoperative urgency symptoms. The patients were divided into groups according to overactive bladder symptom severity and preoperative urodynamic parameters (presence and type of detrusor overactivity, degree of obstruction, bladder contractility). The 3‐month postoperative changes in overactive bladder symptoms were then compared between the groups. Results Overall, there was a statistically significant improvement in mean overactive bladder symptoms score from 9.6 to 2.7 (P
