Abstract
Background:In the TAKT study, a randomized controlled trial of tocilizumab (TCZ) in patients with refractory Takayasu arteritis (TAK) in Japan, the primary end point of time to relapse after induction of remission with glucocorticoid (GC) treatment showed a trend favoring TCZ over placebo (hazard ratio 0.41 [95.41% confidence interval, 0.15-1.10; p=0.0596]),1 but the double-blind period was too short for imaging evaluation.Objectives:To independently evaluate vascular imaging in a post hoc analysis of radiographs from the TAKT study.Methods:Computed tomography images from patients in the TAKT study were evaluated by three independent radiologists who were not involved in the original trial. Patients who received TCZ and had computed tomography images available (n=28) were included. Assessments were made in 22 arteries for the change from baseline in wall thickness (primary end point), dilatation/aneurysm, stenosis/occlusion, or wall enhancement for at least 96 weeks after the start of tocilizumab treatment. Patient-level assessments were also conducted.Results:Among 28 patients who received at least one dose of TCZ and for whom images were available, 86.7% of 22 arteries had improved/stable (no progression) wall thickness at week 96. The proportions of patients with no progressed, partially progressed, or newly progressed lesions were 57.1%, 10.7%, and 28.6% for wall thickness, and the proportions without progressed lesions were 92.9% for dilatation/aneurysm and 85.7% for stenosis/occlusion (Figure 1). Patients with newly progressed lesions, reflecting more refractory disease, were receiving glucocorticoid doses that could not be reduced below 0.1 mg/kg/day at week 96.Conclusion:Approximately 60% of patients with TAK treated with tocilizumab did not experience progression in wall thickness. Few patients experienced progressive dilatation/aneurysm or stenosis/occlusion. Wall thickness progression likely resulted from refractory TAK. Patients who experience this should be monitored regularly by imaging, and additional glucocorticoid or immunosuppressive treatment should be considered to avoid vascular progression.References:[1]Nakaoka Y et al.

Abstract
The transcervical resectoscope (TCR) is used for resecting a submucous myoma (SMM). Safe grasping of an SMM with forceps and its complete resection under transabdominal ultrasound (TAUS) guidance is not always easy. SMMs are slippery, making them difficult to grasp. The SMM moves right to left and anterior to posterior when the surgeon tries to grasp it with placental forceps. Surgeons could use small Martin forceps (65% smaller) to grasp SMMs safely and tightly under direct TCR (transcervical resectoscope) observation. We present a case in which this operative procedure was used to remove an SMM with Figure and Video. The benefits of this procedure are enormous and could be immeasurably important to hysteroscopists and gynecologists.

Abstract
Mesoderm-specific transcript (Mest) is a distinct gene associated with adipocyte differentiation and proliferation. The mechanisms regulating expression of the Mest gene are not established. Therefore, we investigated Mest gene expression during adipogenic differentiation in murine 3T3-L1 preadipocytes and adipose-derived stromal cells (ADCs) from C57BL/6J mouse adipose tissue. Expression of Mest mRNA increased significantly in 3T3-L1 cells during differentiation. Additionally, Mest mRNA expression levels were additively enhanced by the inhibition of DNA methylation. Expression levels of the Mest gene were also markedly elevated in differentiating ADCs in vitro. Additionally, we showed that Mest mRNA can be upregulated by increasing intracellular cAMP, and that Mest expression is suppressed by inhibition of protein kinase A (PKA). Mest expression was regulated through cAMP-dependent PKA pathways during differentiation of preadipocytes into adipocytes in vitro, supporting the critical role of Mest in proliferation and differentiation of adipocytes.

Abstract
Background The St Gallen International Expert Consensus 2011 has proposed a new classification system for breast cancer. The purpose of this study was to elucidate the relationship between the breast cancer subtypes determined by the new classification system and genomic characteristics. Methods Invasive breast cancers (n = 363) were immunohistochemically classified as follows: 111 (30.6%) as luminal A, 95 (26.2%) as luminal B (HER2 negative), 69 (19.0%) as luminal B (HER2 positive), 41 (11.3%) as HER2, and 47 (12.9%) as basal-like subtypes. Results The high expression of Ki-67 antigen was detected in 236 tumors; no cases of luminal A subtype showed high expression of the Ki-67 antigen, but more than 85% of tumors of the other subtypes showed high expression. In addition, DNA ploidy and chromosomal instability (CIN) were assessed using imaging cytometry and FISH, respectively. In this series, 336 (92.6%) tumors consisted of 129 diploid/CIN- and 207 aneuploid/CIN + tumors. Diploid/CIN- and aneuploid/CIN+ features were detected in 64.9% and 27.9% of luminal A, 41.1% and 49.5% of luminal B (HER2-), 11.6% and 81.2% of luminal B (HER2+), 4.9% and 90.2% of HER2, and 17.0% and 76.6% of basal-like subtypes, respectively. Unlike the luminal B (HER2+), HER2 and basal-like subtypes, the luminal A and luminal B (HER2-) subtypes were heterogeneous in terms of DNA ploidy and CIN. Conclusions It is reasonable to propose that the luminal A and luminal B (HER2-) subtypes should be further divided into two subgroups, diploid/CIN- and aneuploid/CIN+, based on their underlying genomic status.

Abstract
β2 and β3 adrenergic receptors (β2AR, β3AR) and uncoupling protein 1 (UCP1) have been considered as candidate genes for obesity. Although each polymorphism of β3AR Trp64Arg, β2AR Arg16Gly and UCP1 -3826A>G is known to be associated with obesity, the interaction among these polymorphisms is not fully understood. We analyzed β3AR Trp64Arg, β2AR Arg16Gly and UCP1 -3826A>G polymorphisms by the Smart Amplification Process 2 in 222 Japanese subjects without the medication of hypertension, dyslipidemia or diabetes, and investigated the association between the physical and metabolic characteristics and the combination of these polymorphisms. In analysis of the genotypes combination, only the carriers of both β2AR Arg/Arg and UCP1 G/G genotypes had significantly higher waist to hip ratio (p=0.014). In analysis of the alleles combination, a significant difference was observed in waist to hip ratio among the groups stratified by the carrying number of the alleles of β3AR Arg, β2AR Arg and UCP1 G (p=0.026), and the waist to hip ratio was significantly higher in the carriers of four and five risk alleles than in the carriers from zero to three risk alleles (p=0.005). The present study demonstrated the interaction among β3AR Trp64Arg, β2AR Arg16Gly and UCP1 -3826A>G for the accumulation of visceral fat.

Abstract
OBJECTIVE We investigated the image quality of multiplanar reconstruction (MPR) using adaptive statistical iterative reconstruction (ASIR). METHODS Inflated and fixed lungs were scanned with a garnet detector CT in high-resolution mode (HR mode) or non-high-resolution (HR) mode, and MPR images were then reconstructed. Observers compared 15 MPR images of ASIR (40%) and ASIR (80%) with those of ASIR (0%), and assessed image quality using a visual five-point scale (1, definitely inferior; 5, definitely superior), with particular emphasis on normal pulmonary structures, artefacts, noise and overall image quality. RESULTS The mean overall image quality scores in HR mode were 3.67 with ASIR (40%) and 4.97 with ASIR (80%). Those in non-HR mode were 3.27 with ASIR (40%) and 3.90 with ASIR (80%). The mean artefact scores in HR mode were 3.13 with ASIR (40%) and 3.63 with ASIR (80%), but those in non-HR mode were 2.87 with ASIR (40%) and 2.53 with ASIR (80%). The mean scores of the other parameters were greater than 3, whereas those in HR mode were higher than those in non-HR mode. There were significant differences between ASIR (40%) and ASIR (80%) in overall image quality (p<0.01). Contrast medium in the injection syringe was scanned to analyse image quality; ASIR did not suppress the severe artefacts of contrast medium. CONCLUSION In general, MPR image quality with ASIR (80%) was superior to that with ASIR (40%). However, there was an increased incidence of artefacts by ASIR when CT images were obtained in non-HR mode.

Abstract
The purpose of this study was to investigate the reproducibility of volumetric software evaluation and manual evaluation of tumour growth. Three observers manually evaluated whether tumour volume was increasing, if it was unchanged, or if it had decreased in size in 2 serial CT examinations of 45 solid lung cancers. The tumour volumes were calculated 3 times using volumetric software and were evaluated using the same classifications as for manual evaluation. Both data sets were divided into three groups: growth or reduction with consistency among all three evaluations (group A), growth or reduction with consistency between only two evaluations (group B), and others (group C). The volume variation and relative volume variation were calculated from the median volumes measured by volumetric software. Although all 45 tumours were categorised in group A by volumetric software, only 21 tumours were categorised in group A by manual assessment. The relative volume variation of the manual assessment was 88.5 +/- 76.5%, 20.8 +/- 28.3% and 12.9 +/- 12.8% in group A, B and C, respectively. Significant differences were found between groups A and B (p<0.01) and between groups A and C (p<0.001). Inconsistency is often seen in manual assessment; in contrast, evaluation using volumetric software has good reproducibility, even when the relative change in tumour volume is small.

Abstract
OBJECTIVES To assess the association of trunk and leg fat mass (FM) and leg lean tissue mass (LTM) with conventional cardiovascular risk factors. DESIGN Cross-sectional study. SETTING AND SUBJECTS We studied 1249 men and 3007 women (age 20-79 years) who attended a research institute for a health checkup between October 1995 and February 2004. MAIN OUTCOME MEASURES Body mass index, waist circumference (WC), hip circumference (HC), systolic and diastolic blood pressure, total cholesterol, HDL cholesterol, triglycerides, glucose and haemoglobin A(1C) were measured. Trunk FM, leg FM and leg LTM were obtained by dual-energy X-ray absorptiometry. We evaluated the associations between the indices for regional body composition and cardiovascular risk factors, which included hypertension, hypercholesterolaemia, hypo-HDL cholesterolaemia, hypertriglyceridaemia, dyslipidaemia and diabetes mellitus. RESULTS Increase in WC and HC respectively showed increase and decrease in odds ratios of cardiovascular risk factors. Increase in trunk FM by 1 kg significantly increased the risk of the cardiovascular risk factors with the odds ratios ranging between 1.11 and 1.45. Increase in leg FM by 1 kg significantly decreased the risk with the odds ratios ranging between 0.52 and 0.90, except for the nonsignificant results for hypercholesterolaemia and hypo-HDL cholesterolaemia in men. Odds ratios of 1 kg increase in leg LTM were only significant for dyslipidaemia in men and hypercholesterolaemia in women (both 0.93). CONCLUSIONS WC and HC showed opposite and independent associations with cardiovascular risk factors. The favourable association of HC was mainly attributable to that of leg FM.

Abstract
PURPOSE We examined the walking habits of the participants in the 'AIREF Spring Walk' which was held on March 9, 1997 in the western suburb of Fukuoka City. The aim of this walking event was to motivate the citizens, especially sedentary people, to walk by providing them an opportunity to enjoy walking. METHODS The participants walked one of three distances (5 km, 10 km or 20 km) and answered anonymously a questionnaire immediately after finishing (100% response rare). The questionnaire items covered sex, age, district of residence, the distance of the walking course, the source of information on the event, experience of participating in other walking events in the past, and walking habits. RESULTS The participants of this event (n = 1,039, mean age 49.4 +/- 18.9 [SD] years) were characterized by high rates for females (67%), those aged < 50 years (42%), residents of Fukuoka City (89%), those who chose to walk the shorter courses of 5 or 10 km (74%), and those who took part in a walking event for the first time (61%). Information on the event was obtained through other people (32%) such as friends, acquaintances, members of community walking groups or other family members, leaflets (21%) placed in the Fukuoka Health Promotion Center and seven Fukuoka City public health centers; a newspaper published biweekly by the municipal government (13%); and direct mail (11%). For those attending the 5 km course, more participants learned about the event through other family members compared with the other two courses. Participants who answered that they walked regularly constituted 56% of those aged 20 years or older. The rates for regular walkers significantly increased with the older participants (p < 0.01) and those who chose longer courses (p < 0.001). Compared with the regular walkers, those without a walking habit tended to have acquired information on the event from friends, acquaintances or other family members, or at their work sites (35%). The average amount of time spent was 249 +/- 175 min/week (n = 375). As a whole, only 30% of the participants aged 20 years or older walked longer than the amount of time for aerobic exercise recommended by the Health, Labor and Welfare Ministry (HLWM). The rate for those who reached the HLWM recommendations was increased in older subject (p < 0.001). CONCLUSIONS It is concluded that the aim of the walking event was partly accomplished, which was reflected by the relatively high rates of participation sedentary for people, compared with other large walking events. The sedentary participants tended to choose the relatively short distances and obtain the information about the event through other people. Walking promotion programs should be developed to motivate sedentary citizens to walk. The programs should also support regular walkers, many of whom are 50 years old or older, to maintain walking habits with the HLWM recommendations on aerobic exercise.

Abstract
The effects of exercise and mild calorie restriction on heart rate variability (HRV) were investigated in 12 mildly obese, normotensive Japanese women aged 45.8+/-4.2 (SEM) years with a body mass index (BMI) of 27.3+/-0.4 kg/m2. The subjects participated in a 3-month program aimed at increasing physical activity and modifying eating behavior (intervention group). The control group consisted of 12 women (age 50.1+/-4.8 years, BMI 27.2+/-0.6 kg/m2) who did not attend the program. The frequency domain of HRV was calculated from 5-min Holter recordings while the subjects rested in a supine position. After 3 months, BMI decreased to 25.0+/-0.5 kg/m2 (p<0.001 vs baseline) in the intervention group, which was accompanied by decreases in body fat mass, waist circumference, serum total cholesterol and triglycerides, and improvement in insulin sensitivity. The mean and SD of the RR intervals, total power, and low and high frequency power of HRV significantly increased after the intervention, whereas no significant changes were seen for the controls. The changes in these HRV variables (calculated by subtracting the baseline values from the follow-up values) negatively correlated with the change in waist circumference, with the Pearson correlation coefficients being between -0.50 and -0.62 (p<0.05). A negative correlation was also seen between the changes in high frequency power and insulin resistance estimated by homeostasis model assessment (r=-0.49, p<0.05). The combination of exercise and mild calorie restriction led to changes in HRV indicative of an improvement in parasympathetic modulation.

Abstract
1. The pro-inflammatory cytokine tumour necrosis factor (TNF)-alpha is considered to be involved in the development of atherosclerosis by inducing local inflammatory responses in the vascular wall. Because TNF-alpha is also known to affect lipid and glucose metabolism, the association between the circulating concentration of TNF-alpha and atherogenic risk factors was examined in 82 apparently healthy Japanese women (aged 19-69 years; mean age 48.5 years). 2. The mean (+/-SD) serum TNF-alpha concentration was 2.7+/-0.9 pg/mL (range 1.4-5.9 pg/mL). The TNF-alpha concentration showed significant correlations with age (r = 0.28; P = 0.01), body mass index (r = 0.27; P = 0.01), the waist-hip ratio (r = 0.41; P = 0.0002), percentage body fat (r = 0.30; P = 0.006), systolic (r = 0.32; P = 0.004) and diastolic (r = 0.24; P = 0.03) blood pressure, total cholesterol (r = 0.27; P = 0.02) and low-density lipoprotein-cholesterol (LDL-C; r = 0.36; P = 0.001), while the correlations with high-density lipoprotein-cholesterol (r = -0.20; P = 0.08) and insulin resistance estimated by the homeostasis model assessment (HOMA(IR); r = 0.16; P = 0.15) were not statistically significant. 3. When adjusted for age and menopause, TNF-alpha was significantly associated with systolic blood pressure (r = 0.25; P = 0.02) and LDL-C (r = 0.27; P = 0.02). The association between TNF-alpha and LDL-C remained significant when adjustment was made for age, menopause and the waist-hip ratio (r = 0.24; P = 0.03). 4. Our results indicate that TNF-alpha may play a role in modulating blood pressure and LDL-C.

Abstract
One hundred and seven patients with prostate cancer were treated at Mie University Hospital during the past 12 years between 1988 and 1999. They were between 53 and 83 years old, with an average age of 70.8 years old. The clinical stage was defined as A, B, C and D in 3 (2.8%), 19 (17.8%), 50 (46.7%) and 35 (32.7%) patients, respectively. At initial diagnosis, the tumor was well, moderately and poorly differentiated adenocarcinoma in 26 (24.3%), 47 (43.9%) and 34 (31.8%) patients, respectively. The median follow-up period was 52.3 months. The overall 1, 3 and 5-year survival rates were 98.0%, 86.8% and 75.2%, respectively. The 5-year survival rates for stage A, B, C and D were 100%, 93.8%, 82.1% and 56.9%, respectively. A significant difference (p = 0.017) in 5-year survival rate was noted between stage C and D. The 5-year survival rate was 100% for well differentiated, 78.0% for moderately differentiated, and 53.2% for poorly differentiated adenocarcinoma. A significant difference (p = 0.0016) in the 5-year survival rate was noted between well differentiated and poorly differentiated adenocarcinoma. According to the therapy, the 5-year survival rate in stage C was 86.2% for the radical prostatectomy group and 84.0% for the endocrine therapy group. There was no significant difference between these 2 treatment groups. Endocrine therapies, classified into maximum androgen blockade (MAB) and endocrine therapy other than MAB were performed for stage D as an initial therapy. Although the prognosis in the patients treated with MAB was better than that with other endocrine therapies, there was no significant difference between these 2 endocrine treatment groups.

Abstract
To assess upper urinary tract function and determine an ideal continent reservoir capacity, we investigated the relationship between intrareservoir pressure and functional parameters using radioisotope renography. Forty-three patients for whom ileal reservoir construction was performed by Kock pouch (n = 33) or Hautmann's ileal neobladder (n = 14) approaches between November 1984 and September 1996 were studied. After the reservoir contents were catheterized, (99m)Tc-MAG 3 renoscintigraphy was carried out and time activity curves in the kidney (renogram) and reservoir (reservoirgram) were recorded, while saline solution was poured into the reservoir for monitoring of intrareservoir pressure. Three basic abnormal curves were noted in the excretory phase on renograms: a normal downward curve followed by an upward curve, a continuous upward curve associated with or without a sharp decline after the catheterization of the reservoir contents, and episodes of spike waves. Based on these curves, renograms were classified into five types: normal, high pressure, retention, obstruction, and reflux. Abnormal types were noted with 51 of 65 renal units (78.5%) in the Kock pouch group and 15 of 25 renal units (60.0%) in the neobladder group. This examination method may be useful for evaluating urodynamics in the upper urinary tract of patients with a continent ileal reservoir and provide data on adequate voiding volumes for the individual patient.

Abstract
OBJECTIVE To correlate the findings of power Doppler ultrasonography (PDUS) of the prostate with those of site-specific transrectal ultrasonography (TRUS)-guided biopsy. PATIENTS AND METHODS The study comprised 28 patients referred to our institution for TRUS-guided prostate biopsy because of an elevated PSA level and/or abnormal digital rectal examination. PDUS findings were graded 0, 1 or 2; grades 0-1 were considered as negative and grade 2 as positive. The blood volume of each biopsy site was also determined using the mean number (MN) value that represents the average vascularity in a 5-mm square sample. PDUS values were correlated with the histological findings of 147 biopsies with 19 focal lesions. RESULTS Grade 2 was assigned to 19 sites, grade 1 to 52 sites, and grade 0 to 76 sites. Fourteen of the 19 PDUS findings of grade 2 sites revealed carcinoma and five were grade 1. Ten of 35 TRUS-positive sites were carcinomas, three benign prostatic hyperplasia (BPH) and 22 normal. The MN value for prostatic carcinoma was 4.33, for BPH 11.7 and for normal tissue 4.7. The overall sensitivity of PDUS was 74%, the specificity 96% and the positive predictive value 74%. CONCLUSIONS Because TRUS alone cannot detect all cancers, PDUS should be used routinely in all patients undergoing TRUS-guided biopsy, to improve the diagnostic yield of prostate cancer.

Abstract
Paravesical granuloma after herniorrhaphy is an unusual complication due to infected suture material and often mimics bladder or urachal malignancy. We present 3 cases of this disease and reviewed 21 previously reported cases. Our patients underwent hernial repair 2-7 years before examination and presented urinary symptoms. They were treated with antibiotics and underwent exploration of the inguinal wound infection but the symptoms did not resolve. En bloc excision and partial cystectomy were performed and resulted in complete resolution of the symptoms. It is important to consider paravesical granuloma in patients who had undergone herniorrhaphy in the differential diagnosis of bladder or urachal tumors.

Abstract
The patient was a 36-year-old woman with a chief complaint of pain of the urethral meatus. A cyst existed just below the urethral meatus. The paraurethral cyst was removed completely. Histologically, the cyst was lined by stratified squamous epithelium. According to the criteria proposed by Das, paraurethral cysts are classified into 4 groups: epithelial inclusion cysts, Müllarian cysts, Gärtner duct cysts, Skene duct cysts. In this case, the cyst seemed to be an epithelial inclusion cyst. In the Japanese literature, paraurethral cysts have been incompletely classified from an etiological perspective. Differential diagnoses based on the histological findings of the cysts may be important to determine the etiology.

Abstract
We report a case of transitional cell carcinoma in the left renal pelvis, which occurred in a 24-year-old man. He had been treated with cyclophosphamide (CPM) for a period of 27 months for retroperitoneal rhabdomyosarcoma diagnosed at the age of 10. At first 1.2 g CPM had been given twice intravenously for 3 months, followed by oral administration of 41 g CPM for 23 months. Drip infusion pyelography revealed a filling defect in the left renal pelvis. A left renal pelvic tumor was strongly suspected on computerized tomography and magnetic resonance imaging. Left nephroureterectomy was then performed. Histological diagnosis of the left renal pelvic tumor was transitional cell carcinoma, grade 2, pT1N0M0. No recurrence was defected 17 months later. This case seems to be the second case of cyclophosphamide-induced upper urothelial carcinoma reported in Japan.

Abstract
A 74-year-old woman with diabetes mellitus had a high fever, and was treated with antibiotics and insulin in another hospital. She was referred to our department, because CT scan showed the right hydronephrosis and the abnormal gas shadow in the right renal calyces. Ureteral catheterization was performed on the right side and cloudy urine was drained. Urine culture yielded E. coli. Since submucosal emphysematous changes were demonstrated in the bladder mucosa by cystoscopy, she was diagnosed with emphysematous pyelonephritis with emphysematous cystitis associated with diabetes mellitus. Administration of antibiotics and insulin and the ureteral catheter drainage improved her condition immediately. Abnormal gas shadow on CT scan and submucosal emphysema on cystoscopy disappeared. We reviewed 110 cases of emphysematous pyelonephritis and 23 cases of emphysematous cystitis including our case in Japan, and report their clinical characteristics.

Abstract
We retrospectively studied the staging accuracy of endorectal magnetic resonance imaging (MRI) in comparison with transrectal ultrasound examination (TRUS) for 71 localized bladder cancers and 19 localized prostate cancers (PC) radically resected. The accuracy of clinical staging for bladder cancer in endorectal MRI and TRUS was 85.9% and 69.2%, respectively. The presence or absence of the continuity of submucosal enhancement on T2-weighted MRI images could be useful for the staging of bladder cancer. The accuracy of the seminal vesicular invasion for prostate cancer in endorectal MRI and TRUS was 95% and 63%, respectively. To determine whether magnetization transfer contrast (MTC) provides additional information in the diagnosis of prostate cancer, the magnetization transfer ratios (MTRs) were calculated in 22 patients with PC, 5 with benign prostatic hyperplasia (BPH) and 4 controls. The mean MTR in the peripheral zone of the normal prostate (8.0% +/- 3.4 [standard deviation]) showed a statistically significant decrease relative to that in the inner zone of the normal prostate (27.4% +/- 3.4, p < 0.01), BPH (25.5% +/- 3.7, p < 0.01), pre-treatment PC (30.6% +/- 5.9, p < 0.01), and PC after hormonal therapy (20.3% +/- 6.3, p < 0.01). The mean MTR in pre-treatment PC was significantly higher than that in BPH, or in PC after hormonal therapy (p < 0.01). MTC was considered to be useful for conspicuity of prostate cancer lesion.

Abstract
A 72-year-old man was admitted to our hospital complaining of a penile mass. The local biopsy indicated an abscess formation in the corpus cavernosum. In spite of antibiotic treatment, the abscess cavity ruptured to the dorsal skin and the urethra. After cystostomy formation, dorso-caverno-urethral fistula was closed by conservative therapies. Although the patient was followed up with antibiotics on an outpatient basis, necrotic changes in the right foot were noticed and he was diagnosed with arteriosclerosis obliterance in the right lower leg. Therefore, he was referred to an orthopedic clinic for amputation of his right lower leg with cystostomy catheter. This is the 7th case reported in Japan.

Abstract
We describe our experience with extracorporeal shock wave lithotripsy (ESWL) in three patients with coagulation disorders (one case of hemophilia A, and two cases of thromboasthenia). We successfully performed ESWL using factor VIII or transfusion of platelets without any severe hemorrhagic complications, such as perirenal and subcapsural hematomas. We consider that adequate supplement of coagulation factor or platelets may lower the risk of hemorrhagic complications in coagulopathic patients who undergo ESWL.

Abstract
We report a rare case of renal cell carcinoma presenting as diplopia which was caused by a metastasis to the clivus. A 58-year-old man was admitted to our hospital with the chief complaint of diplopia. Head magnetic resonance imaging showed a mass in the clivus accompanied by bone destruction. Metastatic tumor to the skull base was suspected. Further examinations for the primary lesion revealed left renal cell carcinoma. He was relieved of diplopia by radiotherapy to the clivus and subsequently underwent left radical nephrectomy.

Abstract
Lymphocele after renal transplantation is a complication that often requires surgical treatment. We performed laparoscopic drainage for the postoperative lymphocele in two renal transplantation patients. The patients were suffering from perineal discomfort and urinary frequency due to the lymphocele after the renal transplantation. Percutaneous catheter drainages and injections of tissue sclerosing agents such as povidone-iodine solution and tetracycline were not effective. Then fenestration of the lymphocele by laparoscopic technique was done. This procedure made the lymphatic fluid free from the lymphocele in the retroperitoneal space to the peritoneal cavity following creation of a peritoneal window. There were no apparent complications. The patients were free from symptoms and had no relapse 10 months after the operation. We report the procedure and the results of the laparoscopic fenestration.

Abstract
OBJECTIVE The purpose of this study was to investigate normal bladder wall morphology in gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA)-enhanced magnetic resonance (MR) imaging using an endorectal surface coil and to perform histological assessment of submucosal linear enhancement with experimental [14C]-gadolinium-tetraazacyclododecane-tetraacetic acid (Gd-DOTA) autoradiography. METHODS AND MATERIAL MR imaging of the bladder was performed using an endorectal coil in 13 consecutive patients with bladder carcinoma and T1-, T2-, and Gd-DTPA-enhanced spin-echo images of the bladder wall were compared. After injection of [14C]Gd-DOTA into a hamster, autoradiograms of the bladder wall were obtained and compared with serial histological sections. RESULTS The normal bladder wall appeared as a homogeneous layer of intermediate intensity on T1-weighted images. After administration of Gd-DTPA, the bladder wall was visualized as three layers: an inner thin layer of low intensity, a middle layer of marked enhancement, and a thick outer layer of intermediate intensity. The autoradiograms demonstrated dense accumulation of [14C]Gd-DOTA in the submucosal layer. Thus, the inner, middle, and outer layers corresponded to the mucosa, submucosa, and muscularis propria, respectively. The thickness of the bladder wall demonstrated on T2-weighted images was almost equal to that of the outer layer on enhanced T1-weighted images. Thus, T2-weighted images revealed only the muscle layer as an intermediate-intensity band. In the preliminary clinical study, MR imaging invariably showed accurate stages of the bladder carcinoma in 13 patients. CONCLUSION In MR imaging of the normal bladder wall, the submucosa was strikingly enhanced after Gd-DTPA administration, separating the bladder wall into three layers. This may have a potential role in the staging of bladder tumors.

Abstract
A 45-year-old woman with left leg edema was admitted to our hospital because of chyluria from the previous year. Her left leg edema appeared after Caesarean section for her first delivery and hysterectomy at the age of 31. Because microfilaria was not detected, she was diagnosed with postoperative lymphangiomatosis. The instillation of 0.1-0.5% silver nitrate into the renal pelvis was not effective. We however, after percutaneous sclerotherapy to the left inguinal lymph nodes with doxycycline, the chyluria disappeared and her left leg edema improved. Then, the surplus skin of her left lower leg was resected. We considered percutaneous sclerotherapy to be a good procedure for chyluria due to postoperative lymphangiomatosis.

Abstract
A 67-year-old man was referred for further examination of left hydronephrosis. He had undergone anterior resection for rectal cancer 2 years previously and also right lobectomy for a solitary hepatic metastasis one year postoperatively. Antegrade pyelography demonstrated a filling defect in middle portion of the left ureter. Cytology of the aspirated urine was class V. Left nephrourete-rectomy was performed. Histologically metastatic adenocarcinoma with intact ureteral mucosa was demonstrated.

Abstract
BACKGROUND Urolithiasis is a major health problem in the northeast part of Thailand. In this study, we examined the prevalence of renal stone disease and differences of urinary components between stone formers and healthy control subjects in northeastern rural areas of Thailand. METHODS We selected 3 villages in the rural areas of Khon Kaen province in northeast Thailand. Three hundred and sixty-seven persons were asked questions relating to urolithiasis and were examined by abdominal ultrasound (US). We collected a spot urine sample from stone formers and healthy control subjects from each village. RESULTS Abnormal findings by US were detected in 39 individuals (10.6%), and included 31 individuals with renal calculi (8.4%), 16 with hydronephrosis (4.4%), and 1 individual with a renal cyst (0.3%). This yielded a disease rate of urinary stones in this study of 16.9%. The male/female ratio was 2/1 and the average age of the individuals examined was 40.3 +/- 13.9 years. However, there was no significant difference between the urinary parameters of stone formers and the healthy control subjects. CONCLUSION There was a high incidence of renal stone disease in the northeast part of Thailand, but the tendency for hypocitraturia was only found in stone formers.

Abstract
A 67-year-old woman was admitted with aching pain in her left flank and nausea. Bilateral renal infarctions were noticed by CT scan and arteriography. Selective intra-arterial thrombolytic therapy was performed. Urokinase (UK) was administered through a balloon catheter embedded into the occlusive segment of the left renal artery selectively. UK (20,000 units/hour) was continuously infused after short-term high dose UK (360,000) infusion. In spite of recanalization of the occluded artery, CT scan and renoscintigraphy image did not suggest recovery of renal function. Conservative intra-arterial thrombolytic therapy is considered to be the most effective treatment for renal infarction.

Abstract
Selective transcatheter embolization using an interlocking detachable coil (IDC) or detachable balloon was performed in three patients with renal artery aneurysms. All aneurysms were of the saccular type, located on segmental branches of the renal artery. After the embolization procedures, the levels of LDH, GOT, WBC and the body temperature were transitionally elevated in all patients. Complete occlusion of the aneurysms were achieved in all cases. Good clinical results were achieved in two of these patients without any renal dysfunction. However, local infarction of ipsilateral renal parenchyma occurred in one patient immediately after the embolization and a Tc-99m-DMSA renal scintigraphy study suggested renal dysfunction after infarction, and the level of serum renin activity was slightly elevated. Selective transcatheter embolization may constitute an acceptable therapeutic approach for renal artery aneurysms because beside avoiding surgery, it has a low risk of complications.

Abstract
Bosniak classification of renal cystic massesis an extremely useful management tool. Of category I-IV by Bosniak, category III lesion is moderately complicated cyst, which cannot be confidently distinguished from malignancy radiologically. Here, we reviewed the clinical course of 5 patients with pathologically proven category III mass by Bosniak in order to evaluate the usefulness of magnetic resonance imaging (MRI) and renal angiography. Two of the 5 lesions were benign (hemorrhagic cyst) and the other were malignant (RCC). On MRI, the results of 5 lesions were true positive in 1 and false negative in 2. On angiography, the results were true positive in 2 and false negative in 1. MRI has an important role in detection of mass. Angiography is necessary for making a definitive diagnosis of the indeterminate renal cystic masses on US and CT as RCC, but cannot increase enough diagnostic confidence in small cystic renal masses. We experienced indeterminate 2 masses (case 1 and 4) on these four imaging techniques, which were RCC and hemorrhagic cyst, respectively. In category III lesions, if malignant finding was detected by MRI or angiography, we believe that surgical exploration should be performed. But, an absolute decision tree for management of the complicated renal cystic mass has not been published, and further investigation should be required.

Abstract
We report a case of xanthogranuloma of the bladder following herniorrhaphy. The patient complained of urinary frequency, residual feeling, and presented with a solid mass located on the dome of the bladder. He had undergone previous inguinal herniorrhaphy. Transurethral biopsy revealed an inflammatory change. Partial cystectomy was carried out for en bloc removal of the tumor. The histological diagnosis was xanthogranuloma of the bladder. Postoperatively, the symptoms disappeared. This is the sixth case report of xanthogranuloma of the urinary bladder and the first case following herniorrhaphy in the Japanese literature.

Abstract
A 53-year-old man was admitted to our hospital with urinary frequency and miction pain. He had von Recklinghausen's disease with multiple café-au-lait spots and neurofibromatosis. Computed tomography scan and magnetic resonance imaging revealed an invasive bladder tumor 10 cm in diameter, and not metastasis. He was diagnosed as having a bladder tumor (T3a N0 M0 with von Recklinghausen's disease. After balloon occluded arterial infusion (BOAI) chemotherapy, total cystectomy was performed. Pathological diagnosis was transitional cell carcinoma, G3, pT3aN0M0. We reviewed and discussed 97 cases of carcinoma associated with von Recklinghausen's disease reported in the Japanese literature. Only 5 cases of bladder cancer have been reported, including the present case.

Abstract
A statistic survey was made on the clinical results of living and cadaveric renal transplantations performed at our department between October 1980 and June 1996. A total of 38 patients received 6 living and 32 cadaveric renal transplants. The graft and patient survival rates of a living renal transplantation were 83.3% and 100% at 3 years, respectively. The graft survival rate of cadaveric renal transplantation was 66.3% at 3 years and 56.0% at 5 years. In a cadaveric renal transplantation, patients with episodes of acute rejection within 12 months showed a significantly worse graft survival rate. This clinical parameter seems to be a prognostic factor for a long-term graft survival.

Abstract
Pamidronate is a second generation bisphosphonate used for treating tumor-induced hypercalcemia and for preventing the development of new bone metastasis. A 47-year-old man with renal cell carcinoma was admitted in our institution because of hypercalcemia with multiple metastasis in bone, lung and lymph nodes. After embolization of the right renal artery, the patient was treated with pamidronate and interferon-alpha. Intravenous pamidronate significantly reduced bone pain and normalized the serum calcium level. The pulmonary metastasis responded to interferon therapy after 2 months of therapy. Radical nephrectomy was then carried out. Paraaortic lymph nodes were found to be necrosed completely. Ossification of osteolytic lesions was observed after two months of therapy and metastatic lesions in the lung showed complete remission (CR) after six months of therapy.

Abstract
Nineteen patients with renal cell carcinoma with tumor extension into the inferior vena cava (IVC) were investigated between January, 1973 and March, 1994. The patients were between 50 and 78 years old with a mean of 65.9 years. The male to female ratio was 1.7 to 1. Thirteen tumors were on the right side and 6 on the left side. In 12 patients, both nephrectomy and removal of the tumor thrombus were performed. The survival rate in the operated group was 60% at 5 years. Histologically, 7 cases were diagnosed as clear cell subtype and 5 cases as granular cell subtype. From this study, an extended operative intervention such as radical nephrectomy combined with tumor thrombectomy of the IVC with or without cavectomy was suggested in the case of renal cell carcinoma without any other metastatic lesions and histopathologically of the clear cell subtype.

Abstract
In 76 patients with renal cell carcinoma (RCC) we assessed the therapeutic effects of interferon-alpha (IFN-alpha) and the outcome of curative resection by analyzing changes in peripheral blood lymphocyte subsets to try to find prognostic indices. The percentage of activated CD8-positive cells present in blood samples before IFN-alpha therapy was significantly higher in progressive disease (PD) patients who died within 8 months than in PD patients who survived for more than 18 months. The high percentage of activated CD8-positive cells present in postoperative blood samples was the most remarkable characteristic in patients in which RCC recurred. Multivariate analysis showed that the percentage of activated CD8-positive cells in postoperative blood samples was the only predictor of recurrence (hazard ratio 1.29, p value 0.02). Thus, the high percentage of activated CD8-positive cells in postoperative blood samples is, therefore, a useful indicator of poor prognosis.

Abstract
In 10 years the diagnosis of renal angiomyolipoma (RAML) was made in 14 patients (male-to female ratio 1:3.7) at our institution; 1 case was associated with tuberous sclerosis (TS) and 1 case had regional lymph node involvement. A statistical study was done on data taken from 739 cases of RAML in the Japanese literature, including our cases. The male to female ratio was 1 to 3. Twenty eight percent of the cases were associated with TS. The ratio of bilateral cases to the unilateral one was 1 to 3. The main clinical signs were flank pain, abdominal mass, hematuria and fever elevation. Recently the ratio of nephrectomy has decreased to 30%. The percentage of detecting the fat component by ultrasonography (US), computed tomography (CT) and magnetic resonance imaging were 88.1%, 86.5% and 80.8% respectively. The percentages of visualizing hypervascularity, aneurysms, absence of arterio-venous shunt and onion peel appearance by selective renal angiography were 77.3%, 71.4%, 48.1% and 4.9% respectively. Small (less than 3 cm), asymptomatic, simple lesions with adipose component may be observed annually by CT and US until more experiences is gained with surveillance of these patients. Embolization was useful for emergency cases or pre-treatment of nephron sparing surgery, but insufficient by itself. As there still remain problems in the diagnosis of RAML, especially in the case of very small tumors, in the case with almost no adipose component and in the case associated with renal cell carcinoma, the diagnosis of RAML should be made synthetically including angiography.

Abstract
One hundred and eighty-four patients with prostatic cancer were treated at Mie University Hospital from 1973 to 1993. They were between 47 and 90 years old, with an average age of 71.8 years old. One hundred and fifty-eight patients (85.8%) were in either stage C or D. Of the 146 cases histologically examined, 17.8% were well differentiated adenocarcinoma, and 47.9% and 34.2% were moderately and poorly differentiated adenocarcinomas, respectively. The overall 3-year, 5-year and 10-year survival rate were 64.2%, 44.9% and 24.2%, respectively. The patients with high stage and/or poorly differentiated adenocarcinomas revealed worse prognosis. Although the prognosis in the patients treated with estrogen and orchiectomy was better than that with estrogen alone, there was no significant difference between the 2 treatment groups. The prognosis of patients with prostatic cancer has been improved since 1988. A possible explanation is that prostate specific antigen has been introduced as a tumor marker, which might contribute to an accurate diagnosis in prostatic cancer and improve the prognosis of the disease. In conclusion, the diagnosis in lower stage and radical prostatectomy might bring favorable prognosis. In future, safer and more effective chemotherapy and endocrine therapy including LH-RH analogue are awaited, to obtain a better prognosis in the patients with advanced prostatic cancer.

Abstract
Primary small cell carcinoma of the renal pelvis is rare. We report a case of combined small cell and transitional cell carcinoma of the renal pelvis. The patient was a 78-year-old man with macrohematuria. He was diagnosed with right pelvic tumor by right retrograde pyelography and computerized tomography. A right radical nephroureterectomy was performed. Histological sections of the tumor showed a mixture of small cell and grade 2 transitional cell carcinoma. Positivity for Grimelius was noted in the small cell component. Masson-Fontana, chromogranin A, serotonin, keratin, leucocyte common antigen (LCA), neuron specific enolase (NSE), adrenocorticotropic hormone (ACTH), growth hormone (GH) and somatostatin were negative. Ultrastructurally, the tumor cells were tightly packed and attached together by scattered desmosomes. There were no neurosecretory granules. Seven months after operation, the patient died with peritonitis carcinomatosa. At autopsy, a metastatic tumor was found in the liver and retroperitoneal lymph node. Other organs were not involved. Especially, there were no abnormalities in the lungs.
