Transcatheter arterial chemoembolization(TACE) is an imperative method for the managment of inoperable hepatocellular carcinoma(HCC). It is well known that primary HCC frequently invades the portal venous system and forms a tumor thrombus obstructing the portal blood flow which makes unfavorable prognosis of patiebt. We retrospetively reviewed 58 patients who reveived TACE(minimum 3 times) of HCC invading into portal venous system. Group 1(n=29) which showed peripheral portal vein invasion had better clinical and laboratory response. Group 2(n=17) which showed first order portal branch invasion had similar response to Group 3(n=12), which had main portal invasion. Group 1 showed no difference in survival time between TAC and TACE, but, in Group 2 and 3, emboliation with chemotherapy made longer survival than chemotherapy only. Clinical level of AFP was meaningful in Group 1 and 2 as decreasing value. Our results provides that careful selection of TACE and case by case Coil/Gelfoam embolization can improve the mean survival and clinical response when HCC evidently invades portal venous system.

A single ectopic ureter associated with ectopic renal dysplasia is extraordinary rare. We report 2 cases, of which one was a girl with ectopic ureter entering the vagina and the other was a girl with ectopic ureter entering the urethra.

The diagnostic possibility and the incidence of ectopic pregnancy are increasing due to several factor. Furthermore, radioimmunoassay of serum β-HCG and US make it possible to diagnose early before the tubal rupture. A conventional surgical approach has been considered as a choice of treatments. Until recent years, however, surgery may have considerable risk of infertility and sugical hazard. In view of the natural tendency of some ectopic pregnancies to terminate in tubal abortion or complete resorption, we tried to cure ectopic pregnancy with nonsurgical transcervical intervention. Five of 8 patients with unruptured tubal pregnancies, it was possible to inject PGF2a into the tubes or gestational sac. 4 of them were ended up with satisfactory reduction of serum β-HCG level and improvement of symptoms & signs. In only one patient, β-HCG level remained a high level continuously, so salpingectomy was done. As a result, we consider that fluoroscopy-guided transcervical interventional procedure is a useful treatment modality for early unruptured ectopic pregnancy.

Anastomosing hemangioma (AH), a rare benign vascular tumor, is a newly recognized variant of capillary hemangioma. In the microscopic examination, this tumor has characteristic feature of the unique anastomosing sinusoidal capillary sized vessels. It can be misdiagnosed as a malignancy such as renal cell carcinoma or angiosarcoma. Herein, we report a case of AH originating in the right kidney of a 43-year-old man, which was initially considered as cystic renal cell carcinoma on computed tomography (CT). The patient underwent laparoscopic radical nephrectomy, but pathologic result was AH of the kidney. There was no evidence of recurrence or metastasis 5 months after the surgery.

PURPOSE: Increasing evidence suggests that Randalls plaque contributes to the pathogenesis of urinary stone formation. The purpose of our study is to compare the incidence of the abnormal metabolic stone risk factors between the calcium stone former with papillary calcification and the calcium stone former without papillary calcification on unenhanced spiral computed tomography (CT). MATERIALS AND METHODS: A series of patients with calcium stones (n=49) underwent unenhanced spiral CT and complete metabolic evaluation after they consumed a random diet for 1 month after stone removal. Of the 49 patients, 38 patients showed papillary calcification on unenhanced spiral CT and 11 patients did not. Their blood was evaluated by using a multichannel analysis sequential multichannel autoanalyzer (SMA)-20 and PTH tests. The 24-hour urinary constituents were assayed for calcium, oxalate, citrate, total volume, phosphorus and sodium. We compared the incidence of abnormal metabolic risk factors between the two groups. Statistical analysis was performed by chi-square tests. RESULTS: The incidences of hyperuricemia were 27.3% in the patients without papillary calcification and 31.6% in the patients with papillary calcification. The incidences of hypernatriuria were 18.2% versus 42.1%, the incidences of hypercalciuria were 36.4% versus 26.3%, the incidences of hyperuricosuria were 18.2% versus 18.4%, the incidences of hyperoxaluria were zero versus 28.9%, and the incidences of hypocitraturia were 45.5% versus 44.7%, respectively. The difference between the two groups was statistically significant only for hyperoxaluria (p=0.043). CONCLUSIONS: Hyperoxaluria is the only metabolic risk factor that more frequently occurred in the patients with papillary calcification. Our date suggest that hyperoxaluria may be an important factor in the pathogenesis of papillary calcification.

Hem-o-Lok clips (Weck Surgical Instruments, Teleflex Medical, Durham, NC, USA) are widely used in robot-assisted laparoscopic radical prostatectomy because of their easy application and secure clamping. To date, there have been some reports of intravesical migration of these clips causing urethral erosion, bladder neck contractures, and subsequent calculus formation. We report the first case of bladder migration of Hem-o-Lok clips without stone formation after robot-assisted laparoscopic radical prostatectomy. The Hem-o-Lok clips were found during urethral dilation with a guide wire for bladder neck contracture under cystourethroscopy. The Hem-o-Lok clips were floating in the bladder without stone formation and were removed by a cystoscopic procedure.
