, Young Yo Park Bladder cancer is the second most common malignancy in urological field. Most new cases are diagnosed as non-muscle invasive bladder cancer (NMIBC), which includes Ta, T1 or carcinoma in situ. Initial management of NMIBC is endoscopic resection, which allows both treatment and pathological staging. Urologist should consider adjuvant intravesical chemotherapy or Bacillus Calmette-Guerin (BCG) immunotherapy, depending on the tumor grade or stage to prevent recurrence and progression. Patients with muscle invasive bladder cancer (MIBC) are best treated with radical cystectomy. However, radical cystectomy should be considered even in patients with NMIBC with high risk of progression and BCG refractory tumors. Delay of radical cystectomy in these patients might lead decreased disease specific survival. Patients treated by radical cystectomy should undergo any form of the urinary diversion. Ileal conduit is still most common method for urinary diversion. Orthotopic neobladder is generally performed by experienced hands in high volume center. Patients undergoing orthotopic neobladder should be educated and manually skillful to manipulate their diversion. Neoadjuvant cisplatin-based chemotherapy is recommended based on level 1 evidence with survival benefit. Recent updated meta-analysis also demonstrated survival benefit in patients with MIBC treated by adjuvant chemotherapy.

, Dong Hyeon Lee Robot-assisted laparoscopic radical cystectomy (RARC) for the treatment of muscle invasive bladder cancer is being increasingly applied. Radical cystectomy is complex procedure which should be performed with extensive lymph node dissection and urinary diversion. Currently, the techniques of RARC are well-described, and the feasibility and safety of RARC has been demonstrated. While extracorporeal approach is preferred method for urinary diversion, intracorporeal urinary diversion is gaining popularity. Positive surgical margins are similar to large open series but inferior for locally advanced disease. However, local recurrence and survival rates seem equivalent to open series at short and mid-term follow up. Randomized controlled trial should be conducted to rigorously assess the oncologic outcomes of RARC compared to open radical cystectomy.
, Jae Y. Ro The incidence of renal cell neoplasms has been increased in worldwide as well as in Korea. Even though the World Health Organization (WHO) Classification of renal tumors (2004) is currently used, new entities require to be added in the updated classification because of recent modification with our understanding of the molecular biology and different clinical behavior of new renal tumors. In this review, recently described tumors and candidate entities will be discussed. It is of importance to know these new entities for the proper diagnosis, treatment, and their prognosis.

In this study, no decrease in tendency of first-line eradication rate could be found. In addition, the patients with the non-ulcerative gastric disease seemed to show significantly lower eradication rate. This finding suggests eradication treatment may be affected by the category of gastric diseases, and careful considerations should be taken assessing the effects and needs for the

We conducted a retrospective survey with the medical records of the patients with hypertensive disorders in pregnancy, who under went cesarean section from January 1998 to December 2012. We collected data including patients' demographics, anesthesia and maternal and neonatal outcome. According to anesthetic method, the subjects were divided into general anesthesia and regional anesthesia group and the clinical outcome were compared. We reclassified the patients according to the use of magnesium sul fate (MgSO4) and compared the clinical outcomes.
Of the 1,050 hypertensive parturients, 848 (80.8%) patients went through cesarean section. Three hundred and sixty three patients (42.8%) underwent epidural anesthesia, general and spinal anesthesia were used in 268 (31.6%), and 217 (25.6%) patients, respectively. There was no significant difference in maternal and neonatal outcome according to anesthetic method. In the patients administered MgSO4, 1 minute Apgar score was lower and maternal gestational age and birth weight were less than the patients not receiving MgSO4.
Anesthetic methods did not have effect on outcome of cesarean section of the patients with hypertensive disorder of pregnancy.

Typical presentations of VAD are occipital headache or posterior neck pain, with various signs arising from brainstem or cerebellar infarctions. Muscular weakness or sensory change of an ipsilateral arm owing to cervical nerve root involvement in association with the VAD has been reported very rarely. Herein we describe two unusual manifestations of extracranial VAD, which presented with monoplegia of single upper limb.

Although most patients with coronary spasm respond well to medical treatment with vasodilators such as calcium channel blockers and nitrates, some patients show intractable attack of coronary vasospasm despite standard medical therapy. We experienced 50-year-old woman with intractable chest pain due to coronary artery spasm, who suffered from ventricular fibrillation despite continuous intravenous nitrate therapy.

Conventional redo AVR after prior CABG involves resternotomy, dissection and clamping of the patent bypass graft vessel. Favorable results have been reported for AVR following previous CABG; however, the problems of this procedure includes that injury to the patent bypass grafts can result in catastrophic complications. Increasing patient age and comorbidities may increase operative mortality, less invasive percutaneous aortic valve intervention has advanced. However, because there are no sufficient data comparing transcatheter aortic valve intervention with surgical AVR, currently, the surgical approach should still be consider as the standard of treatment for AVR following previous CABG. We report a patient in whom successful conventional AVR was underwent after previous CABG with patent left internal mammary artery.
