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.

Aortic aneurysm and dissections are potentially life threatening conditions. The advent of endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR) has reduced perioperative mortality and morbidity and are now established therapy methods for treatment of aortic disease. Adequate pre- and intraoperative imaging is important for optimal results in endovascular procedures. However, the standard use of CT and angiography may not always be sufficient to provide necessary information required for treatment, and complementary techniques are warranted in selected cases. TEVAR in acute complicated type B aortic dissections is proven effective in several reports, but long-term clinical outcome and aortic remodelling are still not fully evaluated. Intravascular phased array imaging (IPAI) was used in patients undergoing EVAR and TEVAR for aortic aneurysm and dissection. The combined information from IPAI and fluoroscopy allowed exact positioning of the stent graft. The colour Doppler function facilitated detection of blood-flow in relevant arteries during and after the procedures, and it also facilitated control of ceased flow in excluded false lumens or aneurysms. Clinical early and long-term results after TEVAR for acute complicated type B aortic dissection were investigated in all patients treated between 1999 and 2009 at UppsalaUniversityHospital. Results were favourable regarding survival and permanent neurological complications. Long-term follow-up of aortic morphological changes in the same patient group showed overall significant reduction of aortic and false lumen diameters, and an increase of true lumen diameter. Total thrombosis of the false lumen occured more often in patients with DeBakey IIIa aortic dissection, than in IIIb. In conclusion, IPAI may be a complementary tool to traditional imaging modalities in EVAR and TEVAR in selected cases. Long-term clinical outcome is excellent with favourable aortic remodeling after TEVAR in patients with acute complicated type B aortic dissection.
