Abstract
Age-induced erectile dysfunction (ED) is a convoluted medical condition, and restoring erectile function (EF) under geriatric conditions is highly complicated. Platelet-rich plasma (PRP) treatment is an inexpensive cell-based therapeutic strategy. We have aimed to restore EF in aged-ED rats with PRP as a therapeutic tool. Male rats were grouped into aged and young according to age. The young rats were considered as normal control (NC) and treated with saline. Aged were further divided into 2 groups and treated with intracavernous (IC) PRP and saline. Treatment was scheduled at the 9th and 10th week for NC and 41th and 42th week for aged-ED rats, with EF analysis scheduled on the 12th week for NC and 44th week for aged-ED rats, respectively. Erectile response, immunofluorescence staining, and electron microscopic analyses were performed. IC PRP treatment effectively reduced prostate hyperplasia (PH). EF response indicated a significant increase in crucial EF parameters in PRP-treated aged-ED rats. Histological evidence denoted a rigid and restored development of tunica adventitia of the dorsal artery, decreased vacuolation of the dorsal penile nerve, and structural expansion of the epineurium. Masson's trichrome and immunostaining results affirmed an elevated expression of α-smooth muscle actin (α-SMA) in the corpus cavernosum (CC). Ultrastructure findings revealed that PRP effectively rejuvenated degenerating nerves, preserved endothelium and adherent junctions of corporal smooth muscle, and restored the axonal scaffolds by upregulating neurofilament-H (NF-H) expression. Finally, PRP enhanced neural stability by enhancing the axonal remyelination processes in aged-ED rats. Hence, PRP treatment was proven to restore EF in aged-ED rats, which was considered a safe, novel, cost-effective, and hassle-free strategy for EF restoration in geriatric patients.

Abstract
Background: Metastatic prostate cancer (PCa) predicts a poor prognosis and lower likelihood of survival. Osteoblasts (OBs) are known to be responsible for the synthesis and mineralization of bone, although it is unclear as to whether PCa in the prostate gland cooperates with OBs in bone to promote PCa malignant transformation. We aimed to elucidate how primary PCa cells cooperate with distal OBs and contribute to the vicious cycle that leads to metastatic PCa. Methods: N-cadherin, E-cadherin, and Twist protein expression were measured by Western blot. Twist translocation into the nucleus was detected by the immunofluorescence (IF) assay. Enzyme-linked immunosorbent assay (ELISA) detected protein levels in human serum samples. Levels of candidate protein expression were examined by the human cytokine array. Prostate tumor growth and metastasis were analyzed by orthotopic and metastatic prostate cancer models, respectively. Immunohistochemistry (IHC) staining was used to observe ADAM metallopeptidase domain 9 (ADAM9) and WNT1 inducible signaling pathway protein 1 (WISP-1) expression in tissue. Results: Our in vitro and in vivo analyses have now discovered that primary PCa expressing ADAM9 protein enables the transformation of OBs into PCa-associated osteoblasts (PCa-OBs), inducing WISP-1 secretion from PCa-OBs in the bone microenvironment. The upregulation of WISP-1 in bone provided feedback to primary PCa and promoted PCa cell aggressiveness via epithelial-mesenchymal transition (EMT) activity. Elevated levels of WISP-1 expression were detected in the serum of patients with PCa. ADAM9 levels were overexpressed in tumor tissue from PCa patients; ADAM9 blockade interrupted OB-induced release of WISP-1 and also suppressed primary tumor growth and distal metastasis in orthotopic PCa mouse models. Conclusion: Our study suggests that the ADAM9/WISP-1 axis assists with metastatic PCa progression. Thus, targeting the ADAM9/WISP-1 axis may help to prevent the malignant phenotypes of PCa cells.

Abstract
Advanced prostate cancer often develops into bone metastasis, which is characterized by aberrant bone formation with chronic pain and lower chances of survival. No treatment exists as yet for osteoblastic bone metastasis in prostate cancer. The indolamine melatonin (N-acetyl-5-methoxytryptamine) is a major regulator of the circadian rhythm. Melatonin has shown antiproliferative and antimetastatic activities but has not yet been shown to be active in osteoblastic bone lesions of prostate cancer. Our study investigations reveal that melatonin concentration-dependently decreases the migratory and invasive abilities of two osteoblastic prostate cancer cell lines by inhibiting FAK, c-Src, and NF-κB transcriptional activity via the melatonin MT1 receptor, which effectively inhibits integrin α2 β1 expression. Melatonin therapy appears to offer therapeutic possibilities for reducing osteoblastic bone lesions in prostate cancer.

Abstract
This study explored the specific effects of ketamine on bladder function followed by a sequence of histological changes in a rat bladder at fixed time course intervals. The rats were grouped into normal control and experimental animals, and ketamine (100 mg/kg/day) was administrated to the experimental animals for 2, 4, and 8 weeks, respectively; similarly, the control animals received saline. All animals were evaluated for bladder function and histological responses to the treatment. Ultrastructural changes were observed by transmission electron microscopy (TEM). The results showed progressive bladder dysfunctions with hyperactive bladder conditions according to the time course and frequency of exposure to ketamine. Significantly, decreased inter contraction intervals, residual urine volume, peak micturition pressure, and increased micturition frequency were observed. Bladder histology results revealed substantial inflammation and comprehensive submucosa edema in week 2 and 4 rats along with fibrosis and significant bladder detrusor hypertrophy in week 8 rats. TEM analysis revealed bladder wall thickening, deformed blood vessels, detrusor hypertrophy, wobbled gap junction, and barrier dysfunction at different time course levels in experimental animals. These results provided a profound knowledge about the prognosis and step-by-step pathophysiology of the disease, which might help in developing new therapeutic interventions.

Abstract
A series of phenylurea hydroxamic acids incorporating pharmacophores of inhibitors of HDAC inhibitors and VEGFR-2 has been designed. Most of the compounds show antiproliferative activity comparable to that of Vorinostat and Sorafenib, and better EPC inhibitory activity. Enzymatic assays and Western blotting results indicated that compound 14 not only inhibits HDAC but also has slight VEGFR-2 inhibitory activity. A docking study revealed that the polar hydroxamic acid retains the interaction with HDAC through a zinc ion and also interacts with some residues of the active site of VEGFR-2. Despite 14 displaying a weaker VEGFR-2 activity, a possible route to develop potent HDAC/VEGFR-2 inhibitors is suggested.

Abstract
Prostate cancer has high metastatic potential. Men with higher urinary levels of the sleep hormone melatonin are much less likely to develop advanced prostate cancer compared with men with lower levels of melatonin. Melatonin has shown anticancer activity in experimental investigations. Nevertheless, the therapeutic effect of melatonin in metastatic prostate cancer has largely remained a mystery. Analyses of Gene Expression Omnibus data and human tissue samples indicated that levels of matrix metallopeptidase 13 (MMP-13) expression are higher in prostate cancer patients than in healthy cancer-free individuals. Mechanistic investigations revealed that melatonin inhibits MMP-13 expression and the migratory and invasive capacities of prostate cancer cells via the MT1 receptor and the phospholipase C, p38, and c-Jun signaling cascades. Importantly, tumor growth rate and metastasis to distant organs were suppressed by melatonin in an orthotopic prostate cancer model. This is the first demonstration showing that melatonin impedes metastasis of prostate cancer by suppressing MMP-13 expression in both in vitro and in vivo models. Thus, melatonin is promising in the management of prostate cancer metastasis and deserves to undergo clinical investigations.

Abstract
Prostate cancer osteoblastic bone metastases are incurable and associated with chronic bone pain and a high mortality rate. Osteoclast-targeting drugs intended to prevent skeletal-related events associated with prostate cancer bone metastases do not prolong overall survival. Improved understanding of the bone-derived factors that contribute to prostate cancer osteoblastic bone metastases is required to design treatments that will improve morbidities and overall survival. Activated osteoblasts stimulate prostate cancer growth in bone. In this study, we report that prostate cancer conditioned medium (CM) promoted bone morphogenetic protein (BMP)-2, -4 and -7 production and the expression of osteogenic transcription factors Runx2 and osterix in osteoblasts. Treating the prostate cancer CM with antibody against CCN3 (nephroblastoma-overexpressed), a cysteine-rich protein that belongs to the CCN family, reduced all of these increases. Incubation of osteoblasts with CCN3 facilitated phosphorylation of GSK3β and β-catenin. GSK3β and β-catenin inhibitors or siRNAs all abolished CCN3-induced promotion of BMPs, Runx2 and osterix expression in osteoblasts. Our results indicate that prostate cancer-secreted CCN3 enhances BMP, Runx2 and osterix expression in osteoblasts via the GSK3β and β-catenin signaling pathways. This understanding of the role played by CCN3 in osteoblastic prostate bone metastasis may lead to more efficient targeted therapies.

Abstract
PURPOSE This study examined the prognostic associations of pre-treatment quality of life (QoL) with overall survival (OS) and distant metastasis-free survival (DFMS) among patients with head and neck cancer (HNC) who underwent free flap reconstruction. METHODS A cohort of 127 HNC patients who received free flap reconstruction between November 2010 and June 2014 at a hospital were recruited. Pre-treatment QoL was measured by the University of Washington Quality of Life Questionnaire, which contains six physical domains, including speech, swallowing, appearance, saliva, taste and chewing, as well as the six social-emotional domains of pain, activity, recreation, shoulder, mood, and anxiety. Cox regression analyses were performed. RESULTS Results showed that pre-treatment QoL was predictive of OS and DMFS. Of the domains, swallowing, chewing, speech, taste, saliva, pain and shoulder were demonstrated to be significant predictors of OS. Additionally, swallowing, chewing, speech, pain and activity were demonstrated making significant contributions to DMFS. CONCLUSION Our data supported that physical domains of pre-treatment QoL were predictors for OS and DFMS in HNC patients with free-flap reconstruction. Longitudinal studies are warranted to clarify the prognostic abilities of social-emotional domains. Information on pre-treatment QoL should be taken into account to individualize care plan for these patients, and hence prolong their survival.

Abstract
Lymphangiogenesis is an important biological process associated with cancer metastasis. The development of new drugs that block lymphangiogenesis represents a promising therapeutic strategy. Marine fungus-derived compound phomaketide A, isolated from the fermented broth of Phoma sp. NTOU4195, has been reported to exhibit anti-angiogenic and anti-inflammatory effects. However, its anti-lymphangiogenic activity has not been clarified to date. In this study, we showed that phomaketide A inhibited cell growth, migration, and tube formation of lymphatic endothelial cells (LECs) without an evidence of cytotoxicity. Mechanistic investigations revealed that phomaketide A reduced LECs-induced lymphangiogenesis via vascular endothelial growth factor receptor-3 (VEGFR-3), protein kinase Cδ (PKCδ), and endothelial nitric oxide synthase (eNOS) signalings. Furthermore, human proteome array analysis indicated that phomaketide A significantly enhanced the protein levels of various protease inhibitors, including cystatin A, serpin B6, tissue factor pathway inhibitor (TFPI), and tissue inhibitor matrix metalloproteinase 1 (TIMP-1). Importantly, phomaketide A impeded tumor growth and lymphangiogenesis by decreasing the expression of LYVE-1, a specific marker for lymphatic vessels, in tumor xenograft animal model. These results suggest that phomaketide A may impair lymphangiogenesis by suppressing VEGFR-3, PKCδ, and eNOS signaling cascades, while simultaneously activating protease inhibitors in human LECs. We document for the first time that phomaketide A inhibits lymphangiogenesis both in vitro and in vivo, which suggests that this natural product could potentially treat cancer metastasis.

Abstract
TP53 mutation patterns are associated with prognosis of various cancers. This study was designed to investigate the association between TP53 mutation patterns and recurrence patterns in upper urinary tract urothelial carcinoma (UTUC) patients. A total of 165 consecutive UTUC patients who underwent nephroureterectomies were enrolled for measuring mutation patterns of TP53 gene from exome 2 to 11. Bladder recurrence, contralateral UTUC recurrence, and metastases were compared among groups by using log-rank test and Cox proportional hazard model. Single base substitution as an A:T to T:A transversion was noted in 55 (33.3%) patients (AT group). Forty-two (25.5%) patients had TP53 mutations with only other than A:T to T:A transversion (NAT group), and 68 patients (41.2%) had wide-type TP53 (WT group). AT group was predominately female (64%, 52%, 29%, respectively), had a higher incidence of end-stage renal disease (24%, 14%, 10%, respectively), and had more high-grade tumors (82%, 74%, 62%, respectively) compared to NAT and WT groups. With adjustment of tumor grade/stages, bladder and contralateral UTUC recurrence-free survival duration was shortest in NAT (p < 0.001) and AT group (p < 0.001), respectively. NAT group had a shorter metastasis-free survival duration than the other two groups combined (p = 0.018). As a result, A:T to T:A transversion increased contralateral UTUC recurrence risk, but other mutations in TP53 raised the hazard of bladder recurrence and metastases. Therefore, TP53 mutation pattern may be a useful biomarker to predict recurrence patterns of UTUC patients.

Abstract
Epithelial-mesenchymal transition (EMT) has received considerable attention as a conceptual paradigm for explaining metastatic behavior during cancer progression. NOV/CCN3 is a matrix-associated protein involved in many cellular functions. Previous studies have shown that CCN3 expression is upregulated in prostate cancer (PCa) cells and in PCa patients. In this study, we have provided evidence of tumor promoting effects of CCN3, which includes induction of epithelial-to-mesenchymal transition (EMT) and tumor metastasis. We used an orthotopic in vivo model to demonstrate the prometastatic effects of CCN3. Overexpression or knockdown of CCN3 changed the EMT phenotype in PCa cells. Moreover, treatment with recombinant CCN3 promoted EMT in PCa cells. We also found that CCN3 may promote EMT by activating the FAK/Akt/HIF-1α pathway and this activation is responsible for Twist expression. IHC staining confirmed a positive correlation between the expression of CCN3, Twist, and tumor stage in PCa tissue. Our findings provide insight into the involvement of CCN3 in the EMT regulation of prostate cancer. CCN3 is a promising molecular target that may contribute to a novel therapeutic strategy against metastatic PCa.

Abstract
PURPOSE To assess the angiographic and clinical outcomes in patients with erectile dysfunction and isolated penile artery stenoses treated by balloon angioplasty. METHODS In this prospective study, 22 patients (mean age 61.0±7.6 years, range 50-79) with erectile dysfunction and 34 isolated penile artery stenoses (mean 74.9%±9.1%) were enrolled and underwent balloon angioplasty. The mean International Index for Erectile Function-5 (IIEF-5) score at baseline was 10.3±4.5. The mean lesion length was 11.1±9.0 mm (mean reference vessel diameter 1.7±0.4 mm). The primary endpoint was in-segment restenosis ≥50% by pelvic computed tomography angiography (CTA) at 8 months. The 1-year sustained clinical success (IIEF-5 score ≥22 or a ≥4-point change in the IIEF-5 score and no later decline by ≥4) was the secondary outcome measure. RESULTS Procedural success was achieved in 31 (91%) of 34 stenotic lesions; there was 1 flow-limiting dissection and 2 arteries with >30% residual stenosis. At 8 months, 14 of 34 lesions in 13 of 22 patients had CTA-documented binary restenosis. At 1 year, sustained clinical success was achieved in 11 of 22 patients. Of the 9 patients not developing binary restenosis, 8 achieved sustained clinical success. CONCLUSION Our findings establish the safety and efficacy of penile artery angioplasty for patients with erectile dysfunction and isolated penile artery stenoses. They also highlight the unmet need for a more enduring treatment strategy for penile artery stenotic disease.

Abstract
Botulinum neurotoxin A (BoNT-A), derived from Clostridium botulinum, has been used clinically for several diseases or syndrome including chronic migraine, spasticity, focal dystonia and other neuropathic pain. Chronic pelvic or bladder pain is the one of the core symptoms of bladder pain syndrome/interstitial cystitis (BPS/IC). However, in the field of urology, chronic bladder or pelvic pain is often difficult to eradicate by oral medications or bladder instillation therapy. We are looking for new treatment modality to improve bladder pain or associated urinary symptoms such as frequency and urgency for patients with BPS/IC. Recent studies investigating the mechanism of the antinociceptive effects of BoNT A suggest that it can inhibit the release of peripheral neurotransmitters and inflammatory mediators from sensory nerves. In this review, we will examine the evidence supporting the use of BoNTs in bladder pain from basic science models and review the clinical studies on therapeutic applications of BoNT for BPS/IC.

Abstract
AIMS Patients with diabetes are predisposed to develop a variety of complications, including lower urinary tract (LUT) dysfunction. We aimed to examine the associations between glycemic control and LUT dysfunction in women with type 2 diabetes (T2D). METHODS We included 400 women with T2D (age range, 48-75 years) in this cross-sectional analysis. The participants were divided into tertiles according to glycosylated hemoglobin (HbA1c) measurements. The mean HbA1c levels for tertiles 1, 2, and 3 were 6.2% (N=132), 7.1% (N=132), and 8.4% (N=136), respectively. We evaluated LUT dysfunction with the American Urological Association Symptom Index (AUA-SI) questionnaire, uroflowmetry (UFM), and post-void residual (PVR). RESULTS No significant differences were found among HbA1c tertiles regarding storage, voiding and total AUA-SI scores, and prevalence of LUT symptoms. However, women in tertile 3 had higher prevalences of severe LUT symptoms (AUA-SI≥20) and clinically significant PVR (≥100mL) compared to women in the other tertiles. Multivariate analysis revealed that diabetic neuropathy, but not HbA1c, significantly predicted LUT symptoms in women with T2D after adjustment for age, body mass index (BMI) and hypertension. However, HbA1c was associated with an increased risk of developing clinically significant PVR. CONCLUSIONS Our findings do not support significant associations between glycemic control and LUT symptoms in women with T2D. However, women with poor glycemic control are more likely to develop urinary retention than women with proper glycemic control. Clinicians should, therefore, be aware of and educate patients about the association between urinary retention and glycemic control.

Abstract
Bone metastases of prostate cancer (PCa) may cause intractable pain. Wnt-induced secreted protein-1 (WISP-1) belongs to the CCN family (CTGF/CYR61/NOV) that plays a key role in bone formation. We found that osteoblast-conditioned medium (OBCM) stimulates migration and vascular cell adhesion molecule-1 (VCAM-1) expression in human PCa (PC3 and DU145) cells. Osteoblast transfection with WISP-1 shRNA reduced OBCM-mediated PCa migration and VCAM-1 expression. Stimulation of PCa with OBCM or WISP-1 elevated focal adhesion kinase (FAK) and p38 phosphorylation. Either FAK and p38 inhibitors or siRNA abolished osteoblast-derived WISP-1-induced migration and VCAM-1 expression. Osteoblast-derived WISP-1 inhibited miR-126 expression. Moreover, miR-216 mimic reversed the WISP-1-enhanced migration and VCAM-1 expression. This study suggests that osteoblast-derived WISP-1 promotes migration and VCAM-1 expression in human PCa cells by down-regulating miR-126 expression via αvβ1 integrin, FAK, and p38 signaling pathways. Thus, WISP-1 may be a new molecular therapeutic target in PCa bone metastasis.

Abstract
Tumor-associated macrophages (TAMs) are M2-polarized macrophages that infiltrate the tumor microenvironment and promote tumorigenesis. However, the mechanisms by which TAMs modulate prostate cancer (PCa) growth are poorly understood. Here, we found that expression of Nephroblastoma Overexpressed (NOV/CCN3) is upregulated in PCa cells and correlated with M2 macrophage infiltration. RAW264.7 macrophage migration was induced by conditioned media (CM) from various PCa cells in proportion to the cellular level of CCN3 expression and was inhibited by an anti-CCN3 neutralizing antibody. CCN3 and PCaCM treatment skewed RAW264.7 cell differentiation from an M1 phenotype to an M2 phenotype. PCa-derived CCN3 induced focal adhesion kinase (FAK)/Akt/NF-κB signaling in RAW264.7 cells, which resulted in VEGF expression and subsequently increased tube formation in endothelial progenitor cells. Finally, PCa-secreted CCN3 stimulated RAW264.7 cells and promoted angiogenesis in the chick chorioallantoic membrane assay (CAM), and increased tumor growth and tumor-associated angiogenesis in a PCa xenograft mouse model. Our results indicate that PCa-secreted CCN3 can recruit macrophages and skew their differentiation to an M2 phenotype. In turn, CCN3-stimulated macrophages contribute to VEGF-dependent angiogenesis. This study reveals a novel mechanism by which TAMs enhance PCa angiogenesis and identifies a potential therapeutic target for PCa.

Abstract
PURPOSE To present oncologic results of laparoscopic radical prostatectomy (LRP) monotherapy for men with high-risk, localized prostate cancer, and to find factors associated with a good prognosis via surgery alone. PATIENTS AND METHODS Between 2002 and 2009, 241 men underwent LRP at an Asian tertiary referral center. Among them, we retrospectively identified 85 (35.3%) men who met the D'Amico's high-risk criteria: Prostate-specific antigen level >20 ng/mL, Gleason score of 8 to 10, or clinical stage ≥T2c. Perioperative parameters were analyzed against biochemical recurrence (BCR)-free survival. RESULTS At a median follow-up of 54 months, BCR developed in 28 (34.1%), with an actuarial BCR-free survival rate of 63.3% at 5 years. Pathologically, 37.6% of the men had organ-confined (OC) disease. Positive surgical margins (PSM) were identified in 49.4% of the patients. A favorable pathologic outcome, defined as OC(+)PSM(-), was observed in 24 patients and associated with a 5-year BCR-free survival rate of 87.0%, compared with 100%, 54.0%, and 46.4% in men with OC(+)PSM(+), OC(-)PSM(-) and OC(-)PSM(+) disease (log-rank, P=0.008). The overall positive lymph node rate was 14.1%. Men (65.9%) with only one D'Amico risk factor had a 5-year BCR-free survival rate of 76.9%, compared with 34.6% in men (34.1%) with ≥2 risk factors (log-rank, P<0.001). CONCLUSIONS Radical prostatectomy monotherapy performed laparoscopically or robotically appears to be an option for high-risk prostate cancer, especially in men with a single D'Amico risk factor. Men with ≥2 risk factors are more prone for BCR to develop after surgery and may need second-line therapy.

Abstract
Aristolochic acid (AA), a component of all Aristolochia-based herbal medicines, is a potent nephrotoxin and human carcinogen associated with upper urinary tract urothelial carcinoma (UUC). To investigate the clinical and pathological characteristics of AA-induced UUC, this study included 152 UUC patients, 93 of whom had been exposed to AA based on the presence of aristolactam-DNA adducts in the renal cortex. Gene sequencing was used to identify tumors with A:T-to-T:A transversions in TP53, a mutational signature associated with AA. Cases with both aristolactam-DNA adducts and A:T-to-T:A transversions in TP53 were defined as AA-UUC, whereas patients lacking both of these biomarkers were classified as non-AA-UUC. Cases with either biomarker were classified as possible-AA-UUC. Forty (26%), 60 (40%), and 52 (34%) patients were classified as AA-UUC, possible-AA-UUC and non-AA-UUC, respectively. AA-UUC patients were younger (median ages: 64, 68, 68 years, respectively; p=0.189), predominately female (65%, 42%, 35%, respectively; p=0.011), had more end-stage renal disease (28%, 10%, 12%, respectively; p=0.055), and were infrequent smokers (5%, 22%, 33%, respectively; p=0.07) compared to possible-AA-UUC and non-AA-UUC patients. All 14 patients who developed contralateral UUC had aristolactam-DNA adducts; ten of these also had signature mutations. The contralateral UUC-free survival period was shorter in AA-UUC compared to possible- or non-AA-UUC (p=0.019 and 0.002, respectively), whereas no differences among groups were observed for bladder cancer recurrence. In conclusion, AA-UUC patients tend to be younger and female, and have more advanced renal disease. Notably, AA exposure was associated with an increased risk for developing synchronous bilateral and metachronous contralateral UUC.

Abstract
BACKGROUND The aim of this study was to explore the feasibility and safety of performing laparoendoscopic single-site surgery (LESS) with conventional laparoscopic instruments. METHODS We retrospectively reviewed our data from 175 patients who underwent various urological LESS procedures via the same ergonomic and geometric principles between 2008 and 2011. LESS procedures performed included adrenalectomy (N = 23), radical nephrectomy (N = 5), radical nephroureterectomy with bladder cuff resection (N = 5), varicocelectomy (N = 12), nephropexy (N = 4), lumbar sympathectomy (N = 4), orchiectomy for intra-abdominal testis (N = 1), pyeloureterostomy (N = 1), dismembered pyeloplasty (N = 1), and adult inguinal hernia mesh repair (N = 119). RESULTS All procedures were completed successfully without the use of ancillary ports or articulating instruments except two cases that required laparoscopic conversion. The mean patient age was 48.9 years. Mean operative time was 99.7 min, mean estimated blood loss was 17.3 ml, and mean hospital stay was 2.1 days. There were no intraoperative complications. CONCLUSION According to our ergonomic and geometric principles, use of conventional laparoscopic instruments is feasible and safe in LESS procedures.

Abstract
BACKGROUND The purpose of the article is to report our long-term results of minilaparoscopic inguinal hernia repair in children. METHODS Between September 2003 and September 2008, 161 children with inguinal hernia were treated with minilaparoscopic herniorrhaphy. The asymptomatic contralateral internal ring was routinely explored and repaired if a patent processus vaginalis of not less than 2 cm was noted. Patients who were followed for less than 1 year and those who were lost to follow-up were excluded from the study. Intraoperative and postoperative complications and hernia recurrences were documented. RESULTS In total, 146 patients were eligible for final analysis. A total of 196 minilaparoscopic herniorrhaphies were performed. The mean follow-up period was 3 years. There were 4 hernia recurrences (2%) in 3 boys. There were no procedure-related complications. None of the patients with a negative contralateral exploration or a contralateral patent processus vaginalis of less than 2 cm had a contralateral metachronous inguinal hernia. CONCLUSIONS Our long-term results reveal that minilaparoscopic herniorrhaphy combined with hernia sac transection is a safe and effective alternative treatment to standard open herniotomy.

BACKGROUND This study aimed to evaluate laparoendoscopic single-site (LESS) adrenalectomy via the retroperitoneal approach using the Alexis wound retractor with standard laparoscopic instrumentation. METHODS Since October 2009, seven LESS retroperitoneal adrenalectomies have been completed successfully with a homemade single port created using an Alexis wound retractor as an access platform through a 3-cm incision beneath the tip of the 12th rib. RESULTS All the LESS procedures for these seven patients with adrenal tumors (size, 1.3-6.0 cm; 4 right, 1 left) were completed successfully without traditional laparoscopic conversion or complication. The average operative time was 159 min, and the estimated blood loss was 100 ml. The average hospital stay was 2 days (range, 1-3 days). CONCLUSIONS The preliminary results show that LESS retroperitoneal adrenalectomy is a safe and feasible procedure for functional adrenal tumors using standard laparoscopic instruments.

Abstract
A 65-year-old female suffered from recurrent urinary tract infection and intermittent right-flank soreness when active. Serial renal ultrasonography and supine/erect intravenous (i.v.) pyelography work-up revealed a floating right kidney with a descent of two vertebral bodies. A Laparoendoscopic single-site retroperitoneal nephropexy was performed. A homemade single port was created by using a commercially available wound retractor through a 3-cm incision at the tip of the 12th rib. With conventional 5-mm laparoscopy and instruments, a retroperitoneal nephropexy was perfomed. The procedure was completed successfully without any complication and with minimal blood loss. The total operative time was 110 minutes. The postoperative course was uneventful. The follow-up erect i.v. pyelographies revealed a normal right kidney position without descent. Laparoendoscopic single-site retroperitoneal nephropexy was a safe, effective procedure, according to our initial experience.

Abstract
AIMS The purpose was to analyze urodynamic findings in female diabetic patients with OAB symptoms. METHODS Data from 94 female diabetic patients who underwent urodynamic studies in evaluation of various LUTS were retrospectively reviewed. Urodynamic findings, demographic data, and clinical symptoms were compared between patients with and without OAB. RESULTS Among the 94 subjects analyzed, 34 (36.2%) were diagnosed as OAB. Demographic data were similar between the patients with and without OAB. In the OAB group, patients had significantly higher storage symptom scores and marginally higher voiding symptom scores. On cystometry, the OAB group had a higher percentage of increased bladder sensation (41.2% vs 11.7%, P = 0.001) and detrusor overactivity (29.4% vs 10.0%, P = 0.023). The OAB group had lower peak flow rate (16.2 +/- 5.9 vs 19.3 +/- 6.3 ml/s, P = 0.023), greater PVR volume (60.3 +/- 29.4 vs 45.0 +/- 25.1 ml, P = 0.009), and lower bladder voiding efficiency (BVE, 75.2 +/- 2.8 vs 81.5 +/- 2.9%, P < 0.001). On pressure-flow studies, the OAB group had a higher percentage of BOO (26.5% vs 6.7%, P = 0.008). CONCLUSIONS Our study shows that the most frequent urodynamic finding of OAB in female diabetic patients is increased bladder sensation, followed by detrusor overactivity. Compared to those without OAB, female diabetic patients with OAB are more likely to have impaired voiding function, characterized by lower peak flow rate, greater PVR volume, lower BVE, and a higher percentage of BOO. In these patients, BOO not only causes voiding difficulty but may also contribute to the development of OAB.

Abstract
CONTEXT Diabetic women are more susceptible to develop lower urinary tract symptoms (LUTS), especially overactive bladder (OAB). However, data regarding the effect of components of metabolic syndrome (MS) on this association are conflicting. OBJECTIVE The objective of the study was to examine the potential role of MS in the development of LUTS in diabetic women. DESIGN The study was a prevalence study conducted between 2005 and 2007. SETTING The study was conducted in a university hospital. PARTICIPANTS A total of 518 women with type 2 diabetes aged 50-75 yr were included. They were subgrouped as MS (47.5%) and non-MS (52.5%) groups according to whether they fulfilled the criteria of MS. MAIN OUTCOME MEASURE We used American Urological Association Symptom Index (AUA-SI) to evaluate LUTS and Indevus Urgency Severity Scale to evaluate OAB, respectively. RESULTS Women in the MS group had significantly higher storage and total AUA-SI scores as well as a higher prevalence of LUTS and OAB. Most intriguingly, the number of MS components was strongly associated with the LUTS severity because the AUA-SI scores increased in parallel to the number of components were present. Similar results were found between MS and OAB. Multivariate analysis revealed that peripheral neuropathy, but not MS, significantly predicted LUTS in diabetic women after age adjustment. However, MS remained significantly predictive for LUTS and OAB after additional adjustment for neuropathy. CONCLUSIONS Our results suggest that MS may especially influence LUTS and OAB in diabetic women, probably by compounding the effect of peripheral neuropathy.

Abstract
PURPOSE To compare the outcomes of hand-assisted laparoscopic bilateral nephroureterectomy (HALBNU) for dialysis and kidney transplant patients with clinically localized upper urinary tract urothelial carcinoma (UUT-UC) with those achieved by open bilateral nephroureterectomy (OBNU). MATERIALS AND METHODS Between 1995 and 2006, 49 patients under dialysis or after kidney transplantation underwent simultaneous bilateral nephroureterectomy for clinically presumed localized UUT-UC at our institute. Of those, 33 underwent HALBNU and 16 received conventional open surgery. Perioperative and pathological data and oncological outcomes were collected by chart review. Bladder recurrence, metastasis, and cancer-specific and overall survival were analyzed and compared between both groups. RESULTS The median follow-up for HALBNU and OBNU group was 35 and 46 months, respectively. Totally, 40 patients were identified to have pathologically confirmed urothelial carcinoma of upper urinary tract. HALBNU group was associated with less blood loss, earlier bowel recovery, less narcotic use, shorter hospital stay, and earlier convalescence. The operative time and complication rate were comparable between the two groups. There was no open conversion in the HALBNU group. The two groups were similar in regard to bladder recurrence rate. The overall, cancer-specific, and bladder-recurrence-free survival were also equivalent between the HALBNU and OBNU group (all p > 0.05). CONCLUSION In dialysis and kidney transplant patients with localized UUT-UC, simultaneous bilateral nephroureterectomy with hand-assisted laparoscopic approach offered less perioperative morbidity and, most importantly, comparable intermediate-term oncological and survival results when compared with its open counterpart. A longer follow-up is required to demonstrate the oncological efficacy of this minimally invasive procedure.

Abstract
BACKGROUND Laparoendoscopic single-site surgery (LESS) is a possible advancement for minimally invasive surgical interventions. However, this technique requires a specialized multichannel port for introducing laparoscope and instruments. We present our preliminary experience of using a homemade transumbilical single-port access for performing LESS. METHOD An Alexis wound retractor was placed through the umbilical incision, and a pair of sterile surgical gloves was then snapped onto it. Standard laparoscopic trocars were inserted through the gloves after the upper half parts of the gloves were truncated. Using this port and Roticulator articulating instruments, we performed 14 urologic LESS procedures on porcine laboratory and cadaveric cases, and we performed 10 transabdominal pre-peritoneal inguinal hernia repairs (TAPP), and 5 laparoscopic varicocelectomies on human cases, respectively. All procedures were performed with instruments inserted through this port without the need for any extraumbilical incisions or conversion to standard laparoscopic surgery. RESULTS All LESS procedures were successfully completed without any complications. The time to achieve the transumbilical port ready for subsequent LESS was short (range, 4-8 (median, 6) minutes). The total operative time was between 60 and 190 minutes. No port-related complications were noted, and the cosmetic results were excellent. CONCLUSIONS This homemade transumbilical port offers a safe, reliable, flexible, and cost-effective access for LESS procedures. This technique may be an alternative for current specialized port systems.

Abstract
INTRODUCTION Calcineurin inhibitors (CNI) are known for their renal toxicity. Lower CNI exposure is a reasonable option to mitigate potential CNI-induced renal toxicity. Herein we have presented our long-term results after lower cyclosporine (CsA) exposure in the first year. MATERIALS AND METHODS Between 1997 and 2004, 63 renal transplant recipients received CsA-based immunosuppression. CsA dosing was adjusted according to the 2-hour whole blood concentration (C2) level. We retrospectively reviewed acute rejection and graft survivals rates, as well as whole blood C2 levels. RESULTS Review of serial mean C2 concentrations at 1, 2, 3, 6, and 12 months after transplantation were 1341, 1241, 1191, 1059, and 927 ng/mL, respectively. These levels were slightly lower than those suggested by the Consensus for C2 levels by Levy et al in 2002, namely, 1600 to 2000 ng/mL (mean, 1700); 1400 to 1600 ng/mL (mean, 1500); 1200 to 1400 ng/mL (mean, 1300); 1000 to 1200 ng/mL (mean, 1100), and 800 to 1000 ng/mL (mean, 900), respectively. Acute rejection rate at 3 months and 1 year are 17.5% and 23.8%. Graft survival at 1 year was 97% and at 5 years, 89%. Two patient were lost to fulminant hepatitis and acute myocardial infarction during the first year, which were not associated with underimmunosuppression. CONCLUSION Appropriate CsA C2 levels may be lower among Taiwanese. Our C2 dosing strategy resulted in good outcomes with acceptable side effects in our single-center experience. Appropriate CsA C2 levels for Asians deserve more attention in trials of larger scale; most reference levels are presently concluded from studies of Caucasians.

Abstract
We report a diabetic renal transplant recipient who presented with fever and right lower quadrant abdominal pain. Acute appendicitis was considered initially and she underwent emergent appendectomy. However, persistent symptoms postoperatively made us perform an imaging study to identify the problems. Abdominal and pelvic computed tomography disclosed several focal wedge-shaped lesions of low attenuation in the renal allograft. Acute lobar nephronia was successfully managed with parenteral antibiotics. The patient recovered without any sequela. A renal allograft in the right iliac fossa complicates the diagnosis among acute renal infection, malignancy, acute rejection, and even acute appendicitis. Biopsy of the renal allograft is sometimes needed due to clinically ambiguous imaging results. In this report, we not only detail the clinical course of such a rare case, but also review the previous 3 cases of acute lobar nephronia in renal allografts in the literature.

Abstract
UNLABELLED Swine tissue can express antigens similar to human A/B blood types. We evaluated whether the variation in human blood type influences the human xenoreactive antibody-mediated cytotoxicity and modifies the protective effect of human decay-accelerating factor (hDAF) exogene, a complement activation regulator, on swine endothelium. METHODS Pig aortic endothelial cells were harvested form normal and hDAF transgenic pigs. Cellular viability was evaluated with an MTT assay. RESULTS As compared with that of other human blood types, human serum from blood type O donors induced more prominent cytotoxicity on swine endothelial cells both from hDAF transgenic or normal pigs (P < .05). In addition, this difference of xenoreactive antibody-induced cytotoxicity between treatment with O and other human blood type sera was more evident in hDAF transgenic swine endothelial cells than those of normal pigs (P < .05). The hDAF exogene can significantly protect the endothelial cells from human xenoreactive antibody-mediated cytotoxicty when treated with human serum from AB blood type (P < .05). Our data demonstrated that human ABO blood type significantly affected human xenoreactive antibody-induced cytotoxicity, which may modulate the protective effect of hDAF exogene expression on swine endothelial cells.

Abstract
We describe an unusually located venous aneurysm found incidentally in a 46-year-old man that was presumptively diagnosed as a retroperitoneal mass near the left renal hilum. He presented for constipation and weight loss; an abdominal ultrasound scan disclosed an anechoic lesion in the left retroperitoneum. Abdominal CT showed a 3-cm mass with low density located at the junction of the left para-aortic and perirenal hilar regions that was initially suspected of being metastatic lymphadenopathy with an unknown primary origin or a neurogenic tumor. The mass was resected by a laparoscopic approach, which revealed a round mass with a smooth capsule and roots connecting to the paraspinal muscles. On pathologic examination, the mass showed classic features of a venous aneurysm. At 12-month follow-up, no local recurrence or malignancy was documented.

Abstract
Metastatic hepatocellular carcinoma (HCC) to the urinary bladder is very rare. We present the case of a 58-year-old female patient who was diagnosed to have both HCC and cervical cancer. She developed hemorrhagic cystitis 2 years after radiation therapy for cervical cancer. During endoscopic electrocauterization for hemorrhagic cystitis, three small reddish tumors measuring less than 1 cm in diameter and with a raspberry-like appearance were found. Transurethral bladder tumor resection was performed. Pathology confirmed metastatic HCC to the bladder. Due to the similar appearance, these tumors are liable to be misinterpreted as engorged vessels secondary to irradiation if biopsies are not taken. Differential diagnosis by pathology is mandatory for such patients.

Abstract
OBJECTIVE To present our initial experience with laparoscopic partial cystectomy (LPC) in selected patients with various bladder pathologies. PATIENTS AND METHODS Between December 2004 and April 2006, four patients had LPC at our centre (mean age 52 years, range 35-70); the transperitoneal approach was used for three and a pre-peritoneal approach for one. The surgical procedures used sequentially included transurethral incision around the lesion, laparoscopic excision of the lesion (partial cystectomy) and intracorporeal suturing. Laparoscopic pelvic lymphadenectomy was also used for the two patients with malignancy. RESULTS All operations proceeded smoothly; the bladder pathologies included one bladder endometriosis, one bladder leiomyoma, one urothelial carcinoma within the bladder diverticulum and one urachal adenocarcinoma. The mean (range) operative duration was 197.5 (120-300) min, the estimated blood loss 70 (50-100) mL, the hospital stay 6.75 (5-9) days, and duration of Foley catheterization 7.25 (6-9) days. No open conversion was required and no patient had peri-operative complications. The surgical margins were free of cancer and the dissected lymph nodes were negative in those two patients with bladder malignancy. CONCLUSIONS LPC is safe and feasible in selected patients with various bladder pathologies.
