Abstract
Introduction Distant metastasis of T1a renal cell carcinoma is rare and whether metastasis is more probable in patients undergoing hemodialysis remains unclear. We report the autopsy case of a patient undergoing hemodialysis with multiple metastases that rapidly progressed from T1a renal cell carcinoma treated with multimodal therapy including nivolumab. Case presentation A 70-year-old male who underwent hemodialysis was diagnosed with clear cell carcinoma (pT1a, G2) after nephrectomy. Six months post-surgery, bone and lung metastases appeared and treated with radiotherapy and pazopanib, respectively. Nivolumab was administered as second- and fourth-line treatments for lung metastases. The patient died approximately 60 months after initial diagnosis; however, nivolumab controlled disease progression for 24 months. An autopsy revealed the lung's occupation with clear cell carcinoma tumor tissue. Conclusion Nivolumab has potential to control lung metastasis progression. Additionally, rechallenge is possible in patients with renal cell carcinoma undergoing hemodialysis.

Abstract
INTRODUCTION Robot-assisted nephroureterectomy for upper tract urothelial carcinoma has been increasingly performed as a minimally invasive procedure recently. However, there are concerns regarding its adoption in highly complex cases with dense adhesions. PRESENTATION OF CASE An 86-year-old woman presented to our hospital with gross hematuria one year after having undergone robot-assisted sacrocolpopexy using a mesh for pelvic organ prolapse. Cystoscopy revealed hematuria from the right ureteral orifice. Computed tomography suggested right hydronephrosis; retrograde pyelography showed a defect in the right renal pelvis with class V urine cytology of the urine from the right kidney. Based on these findings, a right renal pelvic tumor was diagnosed, and robot-assisted nephroureterectomy was performed. The patient was discharged on postoperative day 7 without complications. DISCUSSION To the best of our knowledge, this is the first case report in which robot-assisted radical nephroureterectomy was performed after robot-assisted sacrocolpopexy with a mesh. Dense tissue adhesions are encountered not only between the bladder and the anterior vaginal wall but also around the right ureter in the pelvis. In this case, dense adhesions were confirmed around the right ureter in the pelvis. CONCLUSION Robot-assisted nephroureterectomy may be considered an option for minimally invasive surgery in cases with a history of pelvic organ prolapse surgery using mesh.

Abstract
Lower urinary tract (LUT) function is controlled by the central nervous system, including higher-order cognitive brain regions. The anterior cingulate cortex (ACC) is one of these regions, but the role of its activity in LUT function remains poorly understood. In the present study, we conducted optogenetic experiments to manipulate neural activity in mouse ACC while monitoring bladder pressure to elucidate how the activity of ACC regulates LUT function. Selective optogenetic stimulation of excitatory neurons in ACC induced a sharp increase in bladder pressure, whereas activation of inhibitory neurons in ACC prolonged the interval between bladder contractions. Pharmacological manipulation of ACC also altered bladder contractions, consistent with those observed in optogenetic experiments. Optogenetic mapping of the cortical area responsible for eliciting the increase in bladder pressure revealed that stimulation to ACC showed more potent effects than the neighboring motor cortical areas. These results suggest that ACC plays a crucial role in initiating the bladder pressure change and the micturition reflex. Thus, the balance between excitation and inhibition in ACC may regulate the reflex bidirectionally.

Abstract
INTRODUCTION We aimed to investigate the expression and prognostic role of NAA10 in clear cell renal cell carcinoma (ccRCC). MATERIAL AND METHODS We performed a gene expression and survival analysis based on the human cancer genome atlas database of ccRCC patients (TCGA-KIRC). RESULTS The patients in the TCGA-KIRC (n = 537) were divided into two subgroups: NAA10-low and NAA10-high expression groups. NAA10-high ccRCC exhibited higher T stages (p = 0.002), a higher frequency of distant metastasis (p = 0.018), more advanced AJCC stages (p < 0.001), a lower overall survival time (p = 0.036), and a lower survival rate (p < 0.001). NAA10-high ccRCC was associated with increased activity of non-specific oncogenic pathways, including oxidative phosphorylation (p < 0.001) and cell cycle progression [G2 to M phase transition (p = 0.045) and E2F targets (p < 0.001)]. Additionally, the NAA10-high tumors showed reduced apoptosis via TRIAL pathways (p < 0.001) and increased levels of activity that promoted epithelial-mesenchymal transition (p = 0.026) or undifferentiation (p = 0.01). In ccRCC, NAA10 expression was found to be a negative prognostic factor in both non-metastatic (p < 0.001) and metastatic tumors (p = 0.032). CONCLUSIONS In ccRCC, NAA10 expression was shown to be a negative prognostic factor related to tumor progression rather than tumor initiation, and high NAA10 expression promoted epithelial-mesenchymal transition and undifferentiation.

Abstract
Immune checkpoint inhibitor (ICI) therapies have broadened the armamentarium for metastatic renal cell carcinoma (mRCC). As the ICI therapy spreads in the clinical settings, immune-related adverse events are more of a concern for clinicians. The present study reports three cases of mRCC treated with pembrolizumab plus axitinib and diagnosed hypopituitarism based on clinical symptoms and hormonal profile. Acute methylprednisolone infusion therapy was necessary in one case because of severe adrenal hypofunction; however, the clinical symptoms of the other two cases were controlled with oral corticosteroid therapy. To the best of our knowledge, there is no report of pembrolizumab plus axitinib related hypopituitarism in the treatment of mRCC. The present cases suggests that hypopituitarism after pembrolizumab plus axitinib treatment for mRCC can be handled with steroid therapy even after the development of hypopituitarism.

Abstract
Introduction Epidermoid cysts are tumors and that rarely occur in intrascrotal extratesticular tissues. It is extremely rare for the tumors to penetrate the penile corpora cavernosa. Case presentation We encountered a 4-year-old and a 6-year-old boy with intrascrotal tumors that penetrated the penile corpora cavernosa. Both the patients underwent tumor resection. In the former case, some of the tumor within the corpora cavernosa was left behind, while in the latter case, the tumor was completely resected. Pathological examination in both cases confirmed the diagnosis of epidermoid cysts. Conclusion We should consider the possibility of epidermoid cysts in children presenting with intrascrotal tumors. Moreover, care should be taken when handling the corpora cavernosa during surgery.

Abstract
Neuroendocrine tumor (NET) is a rare tumor commonly found in the gastrointestinal tract and lungs and rarely originates from and metastasizes to the kidney. We report a case of a 66-year-old man with metastatic rectal NET to the kidney, pancreas and bone following the resection of renal tumor with robot-assisted partial nephrectomy (RAPN). A rectal tumor of 10mm in diameter had been endoscopically resected and diagnosed NET with positive surgical margin 9 years before RAPN. Somatostatin receptor (SSR) scintigraphy revealed the other two metastases postoperatively, therefore is an effective tool to detect primary and metastatic sites of NETs.

Abstract
BACKGROUND We assessed the efficacy and safety of mirabegron, a β3-adrenoceptor agonist, in older adults (≥ 80 years old) with overactive bladder (OAB). METHODS OAB patients aged ≥ 80 years were enrolled in this prospective, single-arm observational study. OAB was diagnosed based on the OAB symptom score (OABSS); i.e., a total score of ≥ 3 points and an urgency score of ≥ 2 points. Patients who received 50 mg mirabegron once daily were evaluated at the baseline and at 4, 8, and 12 weeks. The changes from the baseline in the OABSS, International Prostate Symptom Score (IPSS), OAB questionnaire (OAB-q) score, and Vulnerable Elders Survey (VES-13) score were determined. Adverse events, laboratory tests, 12-lead electrocardiography, the QT interval according to Fridericia's formula (QTcF), uroflowmetry, the post-void residual urine volume (PVR), and the Mini-Mental State Examination (MMSE) score were used to assess safety. RESULTS Forty-three patients (median age: 84 years, range: 80-96 years) were examined. They had high rates of comorbidities and polypharmacy. Mirabegron significantly improved in total score of the OABSS, including urgency and urge incontinence. The total IPSS, IPSS quality-of-life (QOL) index, and OAB-q scores also significantly improved. Mirabegron improved in the VES-13 score. There were no significant changes in laboratory test values, uroflowmetry findings, PVR, the QTcF, or MMSE score. Two patients (4.7%) withdrew from the study after experiencing adverse events. CONCLUSIONS Mirabegron was well tolerated and significantly improved in OAB symptoms, and QOL in older patients. Trial registration The present clinical study was approved by University of Yamanashi Institutional Review Board prior to study initiation (ID1447) and was retrospectively registered with the UMIN Clinical Trials Registry (UMIN-CTR), Japan (UMIN000045996) on Nov 6, 2021.

Abstract
Dysregulation of circadian rhythm can cause nocturia. Levels of fatty acid metabolites, such as palmitoylethanolamide (PEA), 9-hydroxy-10E,12Z-octadecadienoic acid (9-HODE), and 4-hydroxy-5E,7Z,10Z,13Z,16Z,19Z-docosahexaenoic acid (4-HDoHE), are higher in the serum of patients with nocturia; however, the reason remains unknown. Here, we investigated the circadian rhythm of fatty acid metabolites and their effect on voiding in mice. WT and Clock mutant (ClockΔ19/Δ19) mice, a model for nocturia with circadian rhythm disorder, were used. Levels of serum PEA, 9-HODE, and 4-HDoHEl were measured every 8 h using LC/MS. Voiding pattern was recorded using metabolic cages after administration of PEA, 9-HODE, and 4-HDoHE to WT mice. Levels of serum PEA and 9-HODE fluctuated with circadian rhythm in WT mice, which were lower during the light phase. In contrast, circadian PEA and 9-HODE level deteriorated or retreated in ClockΔ19/Δ19 mice. Levels of serum PEA, 9-HODE, and 4-HDoHE were higher in ClockΔ19/Δ19 than in WT mice. Voiding frequency increased in PEA- and 4-HDoHE-administered mice. Bladder capacity decreased in PEA-administered mice. The changes of these bladder functions in mice were similar to those in elderly humans with nocturia. These findings highlighted the novel effect of lipids on the pathology of nocturia. These may be used for development of biomarkers and better therapies for nocturia.

Abstract
OBJECTIVE We investigated the association between overactive bladder (OAB) and urinary metabolites in men. METHODS This prospective observational study included 42 men aged 65-80 years. The 3-day frequency volume chart (FVC), International Prostate Symptom Score (IPSS), and quality of life score were adapted to assess the micturition behavior. Participants with IPSS urgency score ≥2 were included in the OAB group, and those with IPSS urgency score <2 were included in the control group. We performed a comprehensive metabolomic analysis using urine samples. Metabolites were compared between the groups using an unpaired t test and Fisher's exact test in a nonadjusted analysis. Multivariable logistic regression analysis was performed to investigate the association between OAB and the metabolites. RESULTS Overall, 23 men were included in the OAB group and 19 in the control group. There were no differences in the background factors except age between the groups. FVC analysis demonstrated that nocturnal urine volume, 24-h micturition frequency, and nocturnal micturition frequency were significantly higher, and the maximum voided volume was significantly lower in the OAB group than in the controls. Metabolomic analysis revealed 14 metabolites that were differentially expressed between the groups. Multivariate analysis indicated that an increase in the levels of 5-iso prostaglandin F2α-VI (5-iPF2a-VI) and 5-methoxyindoleacetic acid was associated with OAB. CONCLUSION Abnormal urinary metabolites, including metabolites in the tryptophan (5-methoxyindoleacetic acid, 3-indoleacetonitrile, and 3-hydroxyanthranilic acid) and arachidonic acid (5-iPF2a-VI) pathways, play a role in the pathogenesis of OAB in older men.

Abstract
Background: Laparoscopic adrenalectomy (LA) is the standard treatment for adrenal benign tumors, including primary aldosteronism (PA) or Cushing's syndrome (CS). Several obesity-related factors were associated with prolonged total operative time (OT), but perinephric fat characteristics were not assessed. We investigated whether the Mayo adhesive probability (MAP) score, which evaluates perinephric fat characteristics, was associated with OT for LA. Methods: This single-center, retrospective cohort study examined 141 consecutive patients who underwent LA for PA or CS. We reviewed patients' characteristics and OT. MAP scores were recorded using preoperative imaging. The correlation among characteristics data, MAP score, and OT was evaluated. Results: Overall, we assessed 82 women and 59 men. Adrenal tumors were found in 80 PA and 61 CS patients. There were 74 left-sided and 67 right-sided tumors. For all patients, the median age, body mass index, and tumor size were 56 years (interquartile range [IQR] 46-65), 24.1 kg/m2 (IQR 21.7-26.8), and 19 mm (IQR 13-26), respectively. A total of 91 patients had MAP scores of 0, and 50 had MAP >0. The median OT was 183.5 minutes (IQR: 156-224 minutes) in the MAP >0 group and 162 minutes (IQR: 135-194 minutes) in the MAP = 0 group. In single variable analysis (unadjusted), MAP scores >0 and left-sided tumors were correlated with longer OT. Multivariable regression analysis revealed that this correlation was only significant for MAP scores >0. Conclusions: MAP score may be useful in preoperative planning for PA or CS patients undergoing LA.

Abstract
A thirty-eight-year-old man presented with acute urinary retention due to a long complicated strictures between the meatus and the bulbar urethra. During the first surgery, in addition to the penile skin flap, the flap of the incised skin at 10mm outside the scrotum strip-like tissue was moved medially and sutured onto the incised urethra. After 12 months of the first surgery, we performed the urethroplasty from the bulbar urethra to the meatus. Postoperatively, the patient voided without complications. Thus, this technique using a skin flap outside the scrotum is effective in long complicated urethral strictures.

Abstract
BACKGROUND To investigate the feasibility of the fourth arm of the da Vinci Si system for robot-assisted partial nephrectomy (RAPN). METHODS Fifty-eight consecutive patients underwent RAPN with the same port placements. After reviewing the surgical videos and records, 38 patients showing usefulness of the fourth arm were categorized into Group A and those not showing usefulness into Group B. The background data, tumor characteristics, and perioperative outcomes were compared between the groups. RESULTS Group B had a larger proportion of tumors located on the inner side of the kidney, and the console time was significantly longer. Multivariable logistic regression analysis showed that tumors located on the inner side of the kidney were associated with the non-use of the fourth arm of the da Vinci Si system during RAPN. CONCLUSIONS Our findings suggested that use of fourth arm in RAPN by da Vinci Si should be considered for each tumor location.

Abstract
Abstract
Background
Cardiac hypertrophy is a compensatory response to pressure overload that leads to heart failure. Recent studies have shown that Rho signaling has crucial regulatory roles in actin cytoskeleton rearrangement during cardiac hypertrophic responses. Rho is rapidly activated in response to pressure overload, but the mechanisms by which Rho and its downstream proteins control actin dynamics during hypertrophic responses remain unclear.
Objective
To identify the essential roles of mDia1 (Rho-effector molecule) in pressure overload-induced ventricular hypertrophy.
Methods and results
Male wild-type (WT) and mDia1-knockout (mDia1KO) mice (10–12 weeks old) were subjected to transverse aortic constriction (TAC) or a sham operation. The heart weight/tibia length ratio, cardiomyocyte cross-sectional area, left ventricular wall thickness, and expression of hypertrophy-specific genes were significantly decreased in mDia1KO mice 3 weeks after TAC, and the mortality rate was higher at 12 weeks. Echocardiography and the pressure-volume loop indicated that mDia1 deletion increased the severity of heart failure 8 weeks after TAC. Microarray gene expression profiling showed that the induction of immediate early genes due to the TAC operation was significantly lower in mDia1KO mice than WT mice, as was the activation of extracellular signal-regulated kinase (ERK) and focal adhesion kinase (FAK). We examined the role of mDia1 in neonatal rat ventricular cardiomyocytes (NRVMs) exposed to mechanical stress. The siRNA-mediated silencing of mDia1 attenuated stretch-induced ERK and FAK phosphorylation, and gene expression of c-fos. Importantly, loss of mDia1 suppressed an increase in the F/G-actin ratio in response to pressure overload in the mice. In addition, increases in nuclear myocardin-related transcription factors (MRTFs) and serum response factor (SRF) were perturbed in response to pressure overload in mDia1KO mice and to mechanical stretch in mDia1 depleted NRVMs.
Conclusions
Rho-mDia1, through actin dynamics, plays critical roles in pressure overload-induced hypertrophy by regulating ERK and FAK phosphorylation and the transcriptional activity of MRTF-SRF.

Abstract
Abstract
Background
Cardiac sarcoidosis is a cause of epicarditis and sustained life-threatening ventricular arrhythmias. These arrhythmias occasionally arise from epicardial. Positron emission tomogramphy-comututed tomography (PET-CT) is useful for diagnosis with sarcoidosis. However, the usefulness for prediction of ventricular arrhythmias in patients with cardiac sarcoidosis is unknown.
Objective
We hypothesized that the evaluation of pericardial fat inflammation could identify high-risk sarcoidosis patients for ventricular arrhythmias.
Methods
We enrolled 20 consecutive patients with cardiac sarcoidosis performed PET-CT between August 2016 and December 2018. In each case, we measured the maximum standardized uptake value (SUVmax) of pericardial fat around the left atrium, both ventricules, atrioventricular groove, and left main coronary.
Results
Seven patients experienced ventricular tachycardia (VT) or ventricular fibrillation (VF). VT/VF patients had significantly more complete right bundle branch block (P=0.035), larger left atrial dimension (P=0.021), larger left ventricular end-diastolic dimension (P=0.005), lower ejection fraction (P=0.007), and higher E/e' (P=0.004). SUVmax of pericardial fat in the roof of left atrium (LA) and left ventricular (LV) with VT/VF patients were significantly higher than non-VT/VF patients (LA: 1.63 vs 1.32, P=0.0311; LV: 1.84 vs 1.26, P=0.045). The cut-off values of SUVmax derived from the ROC curve in the roof of LA and LV are 1.47 and 1.59 respectively. The Kaplan Meire estimator showed that high SUVmax patients in the roof of LA had significantly more detection of NSVT.
Conclusions
Our results suggest the relationship between SUVmax and VT/VF occurrence in patients with cardiac sarcoidosis. The evaluateon of SUVmax may be useful for VT/VF risk stratification.

Abstract
Abstract
Background
Using excised human left atrial appendage samples, we previously demonstrated that epicardial adipose tissue (EAT) are highly associated with atrial myocardial fibrosis as a substrate of atrial fibrillation (AF). We also reported the relationship between Angptl2 in EAT and atrial fibrosis. However, the mechanism is not clear. The purpose is to clarify the mechanisms underlying the effect of EAT on the atrial myocardium.
Methods
Human peri-left atrial EAT and abdominal subcutaneous adipose tissue (SAT) samples were obtained from 6 cases (2 females, 70.2±13.2 years). 50 mg of EAT and SAT were quickly washed with PBS and centrifuged 1min at 1200rpm. After 3 times this procedures, adipose tissues were cultured in DMEM F12 medium with Fetal bovine Serum (FBS) overnight.
After pre-incubation, EAT and SAT tissues were washed and centrifuge d three times and cultured in medium without FBS for 24hours. Finally, we collected oozed medium (conditioned medium) and used for experiments.
Concentrations of Angptl2 in conditioned medium were measured by ELISA.
To study the effects of conditioned medium, we used “organo-culture” system. Isolated atrium from 8week old male Sprague-Dawley rats were placed on the porous membrane with the endothelial face toward the membrane. After that, loading medium (conditioned medium:culture medium = 1:4), culture medium (control), or recombinant Angptl2 were dropped onto the epicardial face of the atrium once a day and incubated for 7 days (37°C, 5% CO2).
Then, histological and immunohistochemical analysis were performed. We also performed quantitative reverse transcription–polymerase chain reaction (RT–PCR) analysis.
Next, we isolated and cultured neonatal rat fibroblast and loaded Angptl2 for 24 hours.After collected these cells, we performed western blotting analysis.
Results
Atria organo-culture incubated for 7 days with conditioned medium showed global fibrosis. At epicardial side, fibrotic area of EAT group was significantly greater compared to that of SAT and control group (P<0.05).
mRNA of Col1a1, col3a1 and TGFβ1 were significantly increased in EAT group compared with the SAT and control group.
And, the concentration of conditioned medium created from EAT was significant higher than that from SAT (P<0.05).
Then, we dropped 500 ng/ml of recombinant Angptl2 onto the rat atria. Fibrotic area of Angptl22 group significantly greater than that of control with increasing number of α-SMA positive cells, and mRNA of col3a1 and TGFβ1 were significantly increased in Angptl2 group compared with control group.
In cultured fibroblasts, α-SMA and p-ERK expression were increased in Angptl2 group measured by western blotting analysis.
Conclusions
Our results demonstrated that EAT rather than SAT induces atrial myocardial fibrosis. There is a possibility that Angptl2 effused from EAT plays a part in atrial fibrosis thought EAT paracrine effect.

Abstract
Background: Our aim was to investigate the association between serum metabolites and nocturia. Methods: A total of 66 males aged 65–80 years were enrolled in this study and stratified according to micturition behavior, which was characterized in terms of the 24 h frequency volume chart (FVC) for 3 consecutive days, the International Prostate Symptom Score (IPSS), and quality-of-life score. The nocturia group included participants with any total IPSS and ⩾1.5 micturitions/night as the mean of 3 nights, while the control group included participants with total IPSS < 8 and <1.5 micturitions/night. We conducted a comprehensive capillary electrophoresis time-of-flight mass spectrometry (CE-TOFMS) study of plasma metabolites. Between-group comparisons of metabolite levels employed the Welch t test. The relationship between nocturia and metabolite profiles was determined using multivariable logistic regression analysis. Results: Of 66 participants, 45 were included in the nocturia group and 21 in the control group. There were no differences in background factors between the two groups. FVC analysis revealed that urine production during night-time, as well as micturition frequency during daytime and night-time were significantly higher in the nocturia group. CE-TOFMS identified eight metabolites whose plasma levels differed between the two groups. Multivariate analysis indicated that increased levels of lauric acid and imidazolelactic acid, as well as decreased levels of thiaproline and glycerol, contribute to the etiology of nocturia in aged men. Conclusions: Our findings suggest that abnormal serum levels of metabolites in several pathways play a role in the pathogenesis of nocturia in aged men.

Abstract
An elevated serum creatine kinase (CK) level is commonly known as hyperCKaemia, and anaesthesiologists must take into account the potential susceptibility of hyperCKaemia patients to develop malignant hyperthermia during general anaesthesia as well as acute onset of rhabdomyolysis postoperatively. Three paediatric patients with hyperCKaemia were scheduled for orthopaedic surgery. With the consent of their parents, their CK changes were monitored for seven days postoperatively to detect rhabdomyolysis. The results showed that the postoperative CK change patterns were almost the same as those for patients whose CK levels were within reference range. Maximum CK levels tended to be higher in these patients than in the CK reference-range patients studied previously, although the reason remains unclear. This experience and previous studies suggest that measuring CK levels at least on postoperative days 1 and 2 might be better for detecting early signs of rhabdomyolysis, even in paediatric patients with hyperCKaemia.

Abstract
Leiomyosarcoma of the scrotum, not involving the testis, epididymis, or spermatic cord, is a very rare type of tumor. A 36-year-old male presented with a slowly growing right scrotal mass (size: 3 × 2 cm). An ultrasound examination revealed a hypoechoic, subcutaneous, solid mass. Laboratory investigations detected normal levels of serum alpha-fetoprotein, beta-human chorionic gonadotropin, and lactate dehydrogenase. The mass was slowly growing and surgically resection was performed diagnosing leiomyosarcoma with histological examination. Wide local excision with a 2-cm margin around the operative scar and right orchiectomy were performed as second surgery. The patient has not suffered recurrence for 28 months.

Abstract
AIMS The sensation of bladder fullness (SBF) is triggered by the release of ATP. Therefore, the aim of this study was to investigate whether time-dependent changes in the levels of stretch-released ATP in mouse primary-cultured urothelial cells (MPCUCs) is regulated by circadian rhythm via clock genes. METHODS MPCUCs were derived from wild-type and Clock mutant mice (ClockΔ19/Δ19 ), presenting a nocturia phenotype. They were cultured in elastic silicone chambers. Stretch-released ATP was quantified every 4 h by ATP photon count. An experiment was also performed to determine whether ATP release correlated with the rhythm of the expression of Piezo1, TRPV4, VNUT, and Connexin26 (Cx26) in MPCUCs regulated by clock genes with circadian rhythms. MPCUCs were treated with carbenoxolone, an inhibitor of gap junction protein; were derived from VNUT-KO mice; or treated with Piezo1-siRNA, TRPV4-siRNA, and Cx26-siRNA. RESULTS Stretch-released ATP showed time-dependent changes in wild-type mice and correlated with the rhythm of the expression of Piezo1, TRPV4, VNUT, and Cx26. However, these rhythms were disrupted in ClockΔ19/Δ19 mice. Carbenoxolone eliminated the rhythmicity of ATP release in wild-type mice. However, time-dependent ATP release changes were maintained when a single gene was deficient such as VNUT-KO, Piezo1-, TRPV4-, and Cx26-siRNA. CONCLUSIONS ATP release in the bladder urothelium induces SBF and may have a circadian rhythm regulated by the clock genes. In the bladder urothelium, clock gene abnormalities may disrupt circadian ATP release by inducing Piezo1, TRPV4, VNUT, and Cx26. All these genes can trigger nocturia.

Abstract
We previously showed that bladder functions are controlled by clock genes with circadian rhythm. The sensation of bladder fullness (SBF) is sensed by mechano-sensor such as Piezo1 and TRPV4 in the mouse bladder urothelium. However, functional circadian rhythms of such mechano-sensors remain unknown. To investigate functional circadian changes of these mechano-sensors, we measured circadian changes in stretch-evoked intracellular Ca2+ influx ([Ca2+] i ) using mouse primary cultured urothelial cells (MPCUCs). Using Ca2+ imaging, stretch-evoked [Ca2+] i was quantified every 4 h in MPCUCs derived from wild-type (WT) and Clock Δ19/Δ19 mice, which showed a nocturia phenotype. Furthermore, a Piezo1 inhibitor GsMTx4 and a TRPV4 inhibitor Ruthenium Red were applied and stretch-evoked [Ca2+] i in MPCUCs was measured to investigate their contribution to SBF. Stretch-evoked [Ca2+] i showed a circadian rhythm in the WT mice. In contrast, Clock Δ19/Δ19 mice showed disrupted circadian rhythm. The administration of both GsMTx4 and Ruthenium Red eliminated the circadian rhythm of stretch-evoked [Ca2+] i in WT mice. We conclude that SBF may have a circadian rhythm, which is created by functional circadian changes of Piezo1 and TRPV4 being controlled by clock genes to be active during wakefulness and inactive during sleep. Abnormalities of clock genes disrupt SBF, and induce nocturia.

Abstract
AIMS To investigate the localization of phosphodiesterase 5 (PDE5) and the molecular mechanism underlying the effect of the PDE5 inhibitor tadalafil in signal transduction in the bladder urothelium. METHODS PDE5 expression in rat bladder tissues and cultured primary rat bladder urothelial cells was evaluated using immunochemistry and western blot assays. Ca2+ influx in cells exposed to isotonic solution, hypotonic solution, a selective transient receptor potential vanilloid 2 (TRPV2) channel agonist (cannabidiol), a selective TRPV4 channel agonist (GSK1016790A), a TRP cation channel melastatin 7 (TRPM7) channel agonist (PIP2), or a purinergic receptor agonist (ATP) in the presence or absence of 10 µM tadalafil was evaluated using calcium imaging techniques. We also evaluated stretch-induced changes in ATP concentration in the mouse bladder in the presence or absence of 100 µM tadalafil. RESULTS Immunochemistry and western blot analyses demonstrated that PDE5 is abundantly expressed in the bladder urothelium and in primary rat urothelial cells. Ca2+ influx induced by hypotonic stimulation, GSK1016790A, or cannabidiol was significantly inhibited by tadalafil, whereas ATP-induced Ca2+ influx was unaffected by tadalafil. PIP2 did not induce Ca2+ influx. ATP release in tadalafil-pretreated bladders significantly decreased compared to control bladders. CONCLUSIONS Tadalafil attenuates Ca2+ influx via TRPV4 and TRPV2, and inhibits ATP release in the bladder urothelium. These findings indicate that tadalafil functions as an inhibitor of urothelial signal transduction.

Abstract
OBJECTIVES We evaluated the association between lower urinary tract symptoms (LUTS) and the expression of connexin (Cx) and transient receptor potential (TRP) channel on urothelial cells non-invasively collected from voided urine in humans. METHODS A total of 55 patients (36 males and 19 females, median age: 71 years old), who were followed up at University of Yamanashi Hospital, were enrolled in the present study. Urothelial cells were collected from voided urine of patients, and the mRNA expression of each subtype of Cxs and TRP channels was measured using quantitive real-time reverse transcription polymerase chain reaction. We then analyzed the correlation between the expression of Cxs and TRP channels and symptom scores in International Prostate Symptom Scoreand Overactive Bladder Symptom Score, in addition to Interstitial Cystitis Symptom Index (ICSI) from only interstitial cystitis (IC) patients. RESULTS Non-adjusted statistical procedure using Spearman's rank-correlation showed that there were significant correlations between the following expressions and symptom scores; (positive correlations) Cx26 versus urgency score, Cx40 versus nocturia, TRPM2 versus intermittency, TRPV1 versus urge incontinence, (negative correlation) Cx40 versus intermittency, TRPM7 versus pollakisuria. However, a multiple comparison adjustment using Bonferroni correction showed that only Cx40 had a trend of correlation with nocturia in ICSI. CONCLUSIONS The expressions of Cxs and TRP channels on urothelial cells in voided urine could be related to LUTS. Further analysis of urothelial cells in voided urine has the potential to reveal the mechanism of the LUTS and develop new markers with non-invasive methods.

Abstract
Small cell carcinoma of the prostate (SCCP) is rare in clinical practice. It is often accompanied with the syndrome of inappropriate antidiuretic hormone secretion (SIADH). We present a case of SCCP with SIADH that was successfully treated with radiotherapy in the metastatic lymphnodes and prostate. The patient was an 81-year-old male with a castrate-resistant prostate cancer (CRPC) with invaded rectum and multiple metastases of pelvic lymphnodes. Hyponatremia was present. After radiotherapy, serum sodium increased and neuron-specific enolase (NSE) decreased. To our knowledge, this is the first case of SCCP with SIADH treated with radiotherapy to improve hyponatremia.

Abstract
Objectives ClockΔ19/Δ19 mice is an experimental model mouse for nocturia (NOC). Using the bladder mucosa obtained from ClockΔ19/Δ19 mice, we investigated the gene expression rhythms of mechanosensory cation channels such as transient receptor potential cation channel subfamily V member 4 (TRPV4) and Piezo1, and main ATP release pathways including vesicular nucleotide transporter (VNUT) and Connexin26(Cx26), in addition to clock genes. Materials and methods Eight- to twelve-week-old male C57BL/6 mice (WT) and age- and sex-matched C57BL/6 ClockΔ19/Δ19 mice, which were bred under 12-h light/dark conditions for 2 weeks, were used. Gene expression rhythms and transcriptional regulation mechanisms in clock genes, mechanosensor, Cx26 and VNUT were measured in the mouse bladder mucosa, collected every 4 hours from WT and ClockΔ19/Δ19 mice using quantitative RT-PCR, a Western blot analysis, and ChIP assays. Results WT mice showed circadian rhythms in clock genes as well as mechanosensor, Cx26 and VNUT. Their expression was low during the sleep phase. The results of ChIP assays showed Clock protein binding to the promotor regions and the transcriptional regulation of mechanosensor, Cx26 and VNUT. In contrast, all of these circadian expressions were disrupted in ClockΔ19/Δ19 mice. The gene expression of mechanosensor, Cx26 and VNUT was maintained at a higher level in spite of the sleep phase. Conclusions Mechanosensor, Cx26 and VNUT expressed with circadian rhythm in the mouse bladder mucosa. The disruption of circadian rhythms in these genes, induced by the abnormalities in clock genes, may be factors contributing to NOC because of hypersensitivity to bladder wall extension.

Abstract
Background: Bilateral adrenal tumors are not common in clinical practice, but are an important source of ectopic adrenocorticotropic hormone (ACTH) secretion. Standard operative management for bilateral pheochromocytomas might dictate the removal of the involved adrenal gland and the removal of the contralateral adrenal gland. We present a case of bilateral ACTH-secreting pheochromocytoma treated with staged laparoscopic unilateral total and contralateral subtotal adrenalectomy. Case Presentation: A 58-year-old male with elevated hyperglycemia and general fatigue was hospitalized for pneumonia. CT incidentally revealed bilateral adrenal tumor. Biochemical examination was significant for elevated urinary metanephrine and normetanephrines, and plasma catecholamine level. CT scan of the head, neck, thorax, and pelvis was normal. Under the clinical diagnosis of ACTH-dependent pheochromocytoma, laparoscopic right total adrenalectomy was performed. As endocrinologic examination showed residual ACTH-dependent pheochromocytoma after surgery, laparoscopic left subtotal adrenalectomy was performed. Pathology analysis revealed pheochromocytoma with stained ACTH lesions in both adrenal tumors. Conclusion: This is a rare case of ACTH-secreting bilateral pheochromocytoma effectively treated with staged laparoscopic unilateral total and contralateral subtotal adrenalectomy, in which the production of ACTH was confirmed by immunohistochemical staining.

Abstract
Renal angiomyolipoma (AML) is a benign renal tumor with a risk of rupture in intratumoral aneurysms. Although renal AML in pregnancy is rare, risk of rupture is greater. Management for AML and childbirth is important during pregnancy; however, it is undefined yet. We present a case of hemorrhagic angiomyolipoma in pregnancy that is effectively managed by immediate cesarean section and elective transcatheter arterial embolization.

Abstract
A 34-year-old man presented with sudden voiding dysfunction and lower limb paraplegia. As a central nervous system disorder was suspected, he was referred to the neurology department. Under the diagnosis of neurosarcoidosis, steroid pulse therapy was initiated. To ensure the effect of this therapy, the patient was referred back for urodynamic testing. Urodynamic testing indicated that the urethral sphincter was not relaxed and could not void. Due to the sudden appearance of repeated and refractory opisthotonus, tetanus was strongly suspected. After administration of antibiotics and tetanus immune globulin, those symptoms disappeared.

Abstract
The Hem-o-lok clips (HOLC) is frequently used for hemostasis of the lateral pedicles in robot-assisted prostatectomy (RARP) and laparoscopic radical prostatectomy (LRP). We report a rare post-operative complication, the migration of a HOLC into the bladder leading to calculus formation after RARP. A 54 year-old man underwent RARP with nerve- sparing procedure with HOLCs in the left neurovascular bundle. Three months later, he was referred to our hospital for pollakisuria and spontaneous hematuria. Abdominal ultrasonographic examination and computed tomography (CT) demonstrated a bladder stone that was 7 mm in diameter. On cystourethroscopy, he was noted to have a yellow-colored stone at 9 o'clock position of vesicourethral anastomosis. A cystolithotripsy for a bladder stone was performed until the surface of it was broken. A HOLC with a calculus was revealed and retrieved by stone forceps through the urethra. Since then, Intravesical migration of a HOLC has not been observed.

Abstract
The present study used a dual analysis of voiding behavior and reflex micturition to examine lower urinary tract function in transient receptor potential vanilloid (TRPV)1 knockout (KO) mice and TRPV4 KO mice. In metabolic cage experiments conducted under conscious conditions (i.e., voluntary voiding behavior), TRPV4 KO mice showed a markedly higher voiding frequency (VF; 19.3 ± 1.2 times/day) and a smaller urine volume/voiding (UVV; 114 ± 9 μl) compared with wild-type (WT) littermates (VF: 5.2 ± 0.5 times/day and UVV: 380 ± 34 μl). Meanwhile, TRPV1 KO mice showed a similar VF to WT littermates (6.8 ± 0.5 times/day) with a significantly smaller UVV (276 ± 20 μl). Water intake among these genotypes was the same, but TRPV4 KO mice had a larger urine output than the other two groups. In cystometrogram experiments conducted in decerebrate unanesthetized mice (i.e., reflex micturition response), no differences between the three groups were found in any cystometrogram variables, including voided volume, volume threshold for inducing micturition contraction, maximal voiding pressure, and bladder compliance. However, both TRPV1 KO and TRPV4 KO mice showed a significant number of nonvoiding bladder contractions (NVCs; 3.5 ± 0.9 and 2.8 ± 0.7 contractions, respectively) before each voiding, whereas WT mice showed virtually no NVCs. These results suggest that in the reflex micturition circuit, a lack of either channel is involved in NVCs during bladder filling, whereas in the forebrain, it is involved in the early timing of urine release, possibly in the conscious response to the bladder instability.

Abstract
Chronic HCV-infected patients tend to have vitamin D deficiency, suggesting that vitamin D supplementation may enhance the efficacy of treatment with pegylated interferon (PEG-IFN) and ribavirin (RBV). We therefore assessed the effects of vitamin D supplementation on viral response to PEG-IFN/RBV. Eighty-four patients with HCV genotype 1b were randomized, 42 to oral vitamin D supplementation (1000 IU/day) and 42 to nonsupplementation (control), from week 8 to the end of PEG-IFN/RBV therapy. The primary end point was undetectable HCV RNA at week 24 (viral response [VR]). VR rate at week 24 was significantly higher in the vitamin D than in the control group (78.6% vs 54.8% P = 0.037). Adverse events were similar in both groups. When patients were subdivided by IL28B SNP rs8099917 genotype, those with the TT genotype group showed a significantly higher VR rate at week 24 with than without vitamin D supplementation (86.2% vs 63.3% vs P = 0.044). Although patients with the TG/GG genotype, who were relatively resistant to PEG-IFN treatment, had similar VR rates at week 24 with and without vitamin D supplementation, the decline in viral load from week 8 to week 24 was significantly greater with than without vitamin D supplementation. Multivariate analysis showed that rs8099917 genotype and vitamin D supplementation contributed significantly to VR at week 24. SVR rates were similar in the vitamin D and control groups [64.3% (27/42) vs 50% (21/42), P = 0.19]. Vitamin D supplementation may enhance the effects of PEG-IFN/RBV in HCV genotype 1b-infected patients.
