Purpose: Approximately 20% to 30% of patients with benign prostatic hyperplasia (BPH) require medication or supplementary treatment for their continuous irritative bladder symptoms after transurethral resection of the prostate (TURP). The purpose of this study was to identify any factors related to continuous bladder irritation in patients after TURP. Materials and Methods: Of all patients who underwent TURP from January 2000 to December 2007, 160 who underwent long-term follow-up were selected for this study. The International Prostate Symptom Score (IPSS) was assessed 12 months after TURP, and the patients were divided into two groups: one group with an irritative bladder symptom score on the IPSS of 7 or less (non-irritative group) and another group with an irritative bladder symptom score on the IPSS of 8 or greater (irritative group). Preoperative urodynamic study variables, preoperative and postoperative IPSS, and the shape of the prostate upon transrectal ultrasonography (TRUS) were analyzed. Results: Of the 160 patients, 93 patients were assigned to the non-irritative group, and 67 were assigned to the irritative group. Initial irritative bladder symptoms were significantly different between the two groups (p < 0.05). Also, a retrourethral enlarged prostate was more frequently observed upon TRUS in the irritative group. Symptoms of urinary frequency, incontinence, and urgency were significantly greater in the irritative group. Although there was no significant difference in the preoperative quality of life between the two groups, postoperative quality of life was significantly worse in the irritative group. Conclusions: The shape of the prostate and the preoperative irritation score correlated significantly with the postoperative severity of irritative bladder symptoms. Therefore, physicians should be cautious when performing TURP in patients with a retrourethral enlarged prostate and severe irritative symptoms.
