Impact of asymptomatic prostatitis on re-operations due to urethral stricture or bladder neck contracture developed after TUR-P

To evaluate the relationship between pathologically proven prostatic inflammation (PI) and re-operation rates due to urethral stricture (US) or bladder neck contracture (BNC) after transurethral resection of prostate (TUR-P). We have retrospectively reviewed the data of 917 consecutive TUR-P cases. Eligible patients (n = 276) were grouped with respect to presence of PI on TUR-P pathology; Group1: PI (+) (n = 67, 24.3%), and Group2: PI (-) (n = 209, 75.7%). The "re-operation" was defined as internal urethrotomy or bladder neck resection performed for BNC or US. Groups were compared with respect to descriptive data and need for re-operation. Logistic regression analysis was performed to estimate the independent risk factors for the development of BNC and US. P values under 0.05 were considered significant. Of the patients, 38 (13.8%) needed re-operation while 238 (86.2%) did not. The re-operation rate in Group1 was significantly higher than Group2 (29.8 vs. 8.6%, P < 0.001). In logistic regression analysis, duration of initial TUR-P and PI were found to be independent risk factors for development of BNC or US after TUR-P. Prostatic inflammation on TUR-P pathology is an independent variable affecting the development of US or BNC. Our results should be supported by prospective studies including higher number of patients.
