Urachal carcinoma is an uncommon neoplasm associated with a poor prognosis. We have encountered two another cases of urachal adenocarcinoma recently 5 years after our first report. The common sign of urachal cancer was painless hematuria. We diagnosed the specific site of origin preoperatively by means of computerized tomography. One patient was performed partial cystectomy and another was total cystectomy with double barrel ureterocutaneostomy. A brief review of the literature of urachal adenocarcinoma was also made.

The term "Milk of calcium" has been borrowed from a somewhat similar condition encountered in the gallbladder. The coexistence of stone in a caliceal diverticulum is well known but milk-of-calcium is unusual in this structure. Recently we experienced a case of milk-of-calcium in a pyelocaliceal diverticulum in a 44 year old man, so we report this case with a brief review of the literature.

For more than 80% of body weight is transmitted through the anterior and middle column, the interbody gap produced by operative reduction of spondylolisthesis is potential risk factor for redisplacement, implant failure, pseudoarthrosis and kyphosis. In biomechanical aspect, augmentation of the anterior column support by interbody fusion is desirable to prevent above problems in surgical treatment of spondylolisthesis. Recently, circumferential fusion is recommended in high-grade spondylolisthesis (grade III, IV, or V ), but there is some controversy about additional interbody fusion in posterior instrumentation for low-grade spondylolisthesis (grade I or II ). So, the purpose of this retrospective study was to compare the segmental sagittal angle in 35 patients of low-grade spondylolisthesis who was performed posterior instrumentation with or without posterial lumbar interbody fusion (PLIF) and to find out the risk factors of the loss of segmental sagittal angle in cases of posterior instrumentation without posterial lumbar interbody fusion (PLIF).

Intramural hematoma(IMH) and penetrating aortic ulcer have been increasingly recognized as causes of acute aortic pathology in addition to aortic dissection. The presence of the intimal tear and a flap traversing the aortic lumen is considered to be a most reliable differential point of aortic dissection and IMH. Transesophageal echocardiography(TEE) has become a valuable modality for the diagnosis, prognosis and management of acute aortic syndrome with the unique advantages of portability and the ability to obtain high-resolution real time images. Endovascular Stent-graft placement over the primary entry tear may be an alternative to open surgery because it can close the intimal tear, which leads to thrombosis of the false lumen, excluding flow through the intimal tear and redirecting aortic flow exclusively into the true lumen. We report 88 year-old male with aortic dissection in descending thoracic aorta, successfully treated with endovascular Stent-graft implantation, which was mimicking intramural hematoma by its appearance and subclinical intimal tear diagnosed exclusively by TEE against other imaging studies.
