BPH¡]Benign prostate hyperplasia¡^is one of the most common chronic diseases in aging male around the globe. TURP¡]Transurethral Resection of Prostate¡^remains the gold standard procedure of choice in BPH treatment. But limited literatures regarding the late complication of TURP was available. For understanding the long term follow up result after TURP, and predict the risk factors for re-intervention, we accessed the hospital claims for TURP from the National Health Insurance database, utilizing data from 2001 to 2007 , in 2001, 2002, 2003 TURP cases, we followed each cohort for 5 years to evaluate the late complications. We also examined the association between the characteristics of patient, hospital and the long term prognosis. In this study we found that from 2001to 2003, totally 1,225 patients under went TURP surgery, with the average age 71.52 ¡Ó 7.65 years (47-94 years). Among these cases, 140 patients (11.43%) experienced secondary surgery. Of the 140 secondary surgery patients, 71 received a secondary TURP, 35 received urethral stricture related surgery and 34 received bladder neck contracture related surgery. The study revealed both the characteristics of the patient and the hospital did not show significantly effect to the long term prognosis. In prediction the risk factors of the secondary surgery, the logistic regression analysis revealed those hospitals located at the central part of Taiwan compared to those at northern part of Taiwan showed a relative risk of 0.58, a significant trend of lower risk for secondary surgery. Otherwise, except this geographic location difference, other characteristics of the patient and the hospital show no significantly risk to the post-TURP second surgery. Conclusion of our study, the result of TURP surgery in Taiwan was fairly equal to that in advanced countries. Patient comorbidity, treated in different level, ownership hospitals resulted no significant difference in post-TURP prognosis.
