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).

We reported a case of postoperative pulmonary embolism associated with pelvic lymphadenectomy for staging prostatic carcinoma. A 66-year-old man was admitted to our hospital complaining of dysuria. Transperineal prostatic biopsy under transrectal ultrasonographic guidance revealed evidence of malignancy. Abdominal CT and whole body scan demonstrated no abnormal findings. Staging pelvic lymphadenectomy was performed safely under general anesthesia. On the 6th postoperative day, the patient had sudden dyspnea and chest pain. EKG showed sinus tachycardia. Chest A-P showed some elevation of left diaphragm. Pulmonary perfusion scan revealed multiple cold area throughout both lung fields. A diagnosis of pulmonary embolism was made. Shock treatment and anticoagulant therapy were successfully performed. This case suggests that attention should be directed to pulmonary embolism as one of the postoperative complication of staging pelvic lymphadenectomy.
