Abstract
Objective: To assess the safety and feasibility of the application of the laparoscopic modality in the perioperative treatment of central liver tumors. Methods: Collecting all the clinical information of a total of 40 patients with central liver tumors who received laparoscopic resection treatment carried out at Department of Hepatological Surgery of People's Hospital of Hunan Provincial from January 2016 to December 2018 to take a retrospective review. There were 19 males and 21 females.The age was (59.5±14.5) years (range: 15 to 71 years) . There were 26 cases of primary hepatic carcinoma (24 cases of hepatocellular carcinoma, 2 cases of cholangiocellular carcinoma) , 8 cases of hepatic cavernous hemangioma, 1 case of metastatic hepatic carcinoma, 5 cases of hepatocellular adenoma. The maximum diameter of tumors were (6.2±2.9) cm (range: 2 to 13 cm) . The patient's information about hepatectomy methods, blocking mode and time of blood flow, operation time, intraoperative blood loss, intraoperative blood transfusion rate, post-operative hospitalization time, perioperative reoperation and postoperative complications were collected. Results: A total of 40 patients all were treated with laparoscopic surgery. The surgical procedure was as follows: 2 patients received the right hepatic lobectomy (Ⅴ, Ⅵ, Ⅶ and Ⅷ segments) , 2 patients received the left hepatic lobectomy (Ⅱ, III and Ⅳ segments) , 13 patients received mesohepatectomy (Ⅳ, Ⅰ and Ⅷ segments) , 2 patients received left hepatic trisegmentectomy (Ⅱ, Ⅲ, Ⅳ and Ⅷ segments) , 2 patients received right hepatic trisegmentectomy (Ⅳ, Ⅴ, Ⅵ, Ⅶ and Ⅷ segments) , 7 patients received Ⅷ segmentectomy, 1 patient received Ⅳ segmentectomy, 3 patients received Ⅴ and Ⅷ segmentectomy, 5 patients received hepatic caudate lobe resection (Ⅰ, Ⅸ segments) , and 3 patients received local tumors resection.Pathological results: there were 26 cases of primary hepatic carcinoma (24 cases of hepatocellular carcinoma, 2 cases of cholangiocellular carcinoma) , 8 cases of hepatic cavernous hemangioma, 1 case of metastatic hepatic carcinoma, 5 cases of hepatocellular adenoma; the pathological reports of all malignant tumor cases all showed negative incisal edge. The operative time was (333±30) minutes (range: 280 to 380 minutes) ; the intraoperative hepatic portal occlusion period was (58±13) minutes (range: 30 to 90 minutes) ; the intraoperative hemorrhage was (173±129) ml (range: 20 to 600 ml) ; the intraoperative blood transfusion rate was 2.5% (1/40) ; the postoperative incidence of bile leakage was 2.5% (1/40) , the hospital discharge of 1 patient with bile leakage was approved after conservative treatments like T pipe decompression and adequate drainage; there was 1 case of abdominal infection and 1 case of pulmonary infection, both of which were discharged from the hospital with conservative treatments; there were no other serious postoperative complications. The postoperative hospital stay was (10.7±2.7) days (range: 6 to 16 days) ; there were no perioperative mortality and reoperation cases. Conclusion: In the centers with abundant laparoscopic hepatectomy experiences, the laparoscopic resection is proved to be safe and feasible in the perioperative treatments of central liver tumors by the highly selective cases, the adequate preoperative assessment and reasonable surgical techniques and approach.

Abstract
Vascular complications are serious problems after kidney transplantation. An aneurysm or rupture in a graft artery is a rare but potentially devastating complication, which may lead to renal function impairment, graft loss, or even death. In this paper, we present two rare vascular complications in the early postoperative course after renal transplantation from the same deceased donor. In the first case, a 49-year-old woman who had spontaneous graft arterial rupture 13 days after kidney transplantation presented with sudden distension in the right lower abdomen. In the second case, a 56-year-old woman recipient with a graft renal arterial pseudoaneurysm presented with decreased urine output and deteriorating renal function 32 days after transplantation. Immediate surgical repair was performed, and fibrin sealant was applied to strengthen the fragile renal arterial wall. Although the function of both graft kidneys recovered well after surgery, the first graft kidney was removed 2 months later because of repeated fungal and bacterial infections. Aggressive surgical reconstruction may preserve graft kidneys in patients with vascular complications after kidney transplantation, but recovery of the graft condition remains a demanding challenge in renal transplantation.

Abstract
OBJECTIVE To compare the therapeutic efficacy and safety of mirabegron monotherapy in male patients with overactive bladder (OAB) with and without bladder outlet obstruction (BOO). MATERIALS AND METHODS Male patients with OAB aged ≥20 years, with or without BOO, receiving mirabegron 25 mg monotherapy once daily, were prospectively enrolled. The treatment results were assessed using global response assessment, international prostate symptom score and subscores, overactive bladder symptom score, patient perception on intensity of urgency scale, patient perception of bladder condition, and quality of life index at 1 and 3 months after treatment. RESULTS Of the 289 enrolled patients (mean age, 71.2 years), 207 did not have BOO (71.6%) and 82 had BOO (28.4%). The baseline OAB symptoms were similar between patients with and without BOO. After mirabegron treatment, the satisfactory rate (global response assessment score ≧1) were similar between those without BOO (61.3%) and with BOO (57.1%). The improvement of quality of life index and patient perception of bladder condition was also found in both groups. However, only patients without BOO had significantly improved international prostate symptom score and subscores, overactive bladder symptom score, and patient perception on intensity of urgency scale. Although most adverse events (AEs) were mild, patients with BOO had significantly higher AEs rate (18.6%) than those without BOO (8.2%, P = .026). CONCLUSION Mirabegron monotherapy in male patients with OAB and BOO was safe. However, the storage symptoms improvement was less in patients with BOO and AEs rate was higher.

Abstract
Purpose Impotence is one of the major complications occurring in prostate cancer patients after radical prostectomy (RP). Self-repair of the injured nerve has been observed in animal models and in patients after RP. However, the downstream signalling is not well documented. Here, we found that the DAPK/CIP2A complex is involved in GAS6/AXL-related Schwann cell proliferation. Materials and Methods The 3 groups were a sham group, a 14-day post-bilateral cavernous nerve injury (BCNI) group and a 28-day post-BCNI group. Erectile function was assessed and immunohistochemistry was performed. The rat Schwann cell RSC96 line was chosen for gene knockdown, cell viability, western blot, immunofluorescence and co-immunoprecipitation assays. Results The intracavernosal pressure was low on the 14th day after BCNI and partially increased by the 28th day. GAS6 and p-AXL expression gradually increased in the cavernous nerve after BCNI. RSC96 cells incubated with a GAS6 ligand showed increased levels of p-ERK1/2 and p-AKT. Moreover, DAPK and CIP2A.p-AXL and p-DAPK and CIP2A complexes were identified by both immunoblotting and co-immunoprecipitation. Conclusion The DAPK/CIP2A complex is involved in GAS6/AXL-related Schwann cell proliferation. CIP2A inhibits PP2A activity, which results in p-DAPK(S308) maintenance and promotes Schwann cell proliferation. CIP2A is a potential target for the treatment of nerve injury after RP.

Abstract
OBJECTIVES Non-contrast computed tomography (NCCT) is not always performed clinically if the diagnosis of ureteral calculi has been confirmed using other radiographic imaging modalities. The aim of this study was to identify predictors of successful extracorporeal shockwave lithotripsy (ESWL) without assistance of NCCT. METHODS We retrospectively reviewed the medical records of patients with symptomatic solitary ureteral stones who underwent ESWL between November 2015 and January 2016. Abdominal plain radiography or intravenous urography were performed before ESWL for localization. The exclusion criteria were repeated sessions of ESWL for the target stone and congenital genitourinary tract anomalies. The demographic characteristics, clinical history, medical charges, or imaging features of the stones were recorded. Successful treatment was defined as no fragments detected on radiography or ultrasonography in 4 weeks. For radiolucent calculi, successful treatment was regarded as cases without hydronephrosis, symptoms, or hematuria. Patients experiencing intractable pain and undergoing subsequent auxiliary surgeries were regarded as having ESWL treatment failure. RESULTS Age (odds ratio [OR], 1.042; 95% confidence interval [CI], 1.007-1.078), history of ipsilateral renal or ureteral calculi episodes (OR, 2.669; 95% CI, 1.281-5.687), stone burden (OR, 3.499; 95% CI, 1.284-9.530), and radiopaque stone (OR, 2.351; 95% CI, 1.049-5.267) were significant predictors of ESWL failure in all patients. CONCLUSIONS For treating symptomatic ureteral stones, those with smaller size, radiolucency, and without a history of ipsilateral renal or ureteral calculi could be considered for first-line therapy with ESWL.

Abstract
Lower urinary tract symptoms (LUTS) are highly prevalent in men and increase with age. Because LUTS are common among elderly men, they are usually considered synonymous with benign prostatic hyperplasia (BPH). Drugs should be the first-line treatment for BPH and surgical intervention should be performed only when there are complications or LUTS refractory to medical treatment. In addition to medical treatment, several minimally invasive therapies, such as thermal therapy, prostatic lift, laser evaporation, or laser enucleation techniques have been developed. Recent investigations have also revealed that bladder dysfunction such as detrusor overactivity and detrusor underactivity may also contribute to male LUTS. In the treatment of LUTS suggestive of BPH (LUTS/BPH), the following questions should be considered: Is there an obstruction? Are we treating BPH or LUTS? Can management targeting BPH reduce LUTS? Should patients with LUTS be treated before bladder outlet obstruction is confirmed? What is the role of transurethral resection of the prostate (TURP) nowadays? Will new techniques provide better outcomes than TURP? This article discusses the current consensus and controversies in the treatment of LUTS/BPH.

Abstract
Mirabegron, which was the first β3-adrenoceptor agonist introduced for use in clinical practice, has been extensively evaluated in overactive bladder (OAB) patients in several phase II and III studies. However, most of the enrolled patients were treatment naive or had experienced a wash-out period before the introduction of mirabegron. No study has reported the treatment results of a direct switch from antimuscarinics to mirabegron, which may more commonly occur in clinical practice. This is an observational study to assess the therapeutic efficacy and safety of directly switching from antimuscarinics to mirabegron in patients with OAB receiving stable antimuscarinic treatment. Moreover, we sought to identify the patients who benefited more from the change.Patients aged ≥20 years with OAB receiving stable antimuscarinics for >3 months were enrolled. Antimuscarinics were discontinued in all patients and mirabegron 25 mg, once daily was initiated. Primary end-point was global response assessment (GRA) at 1 month after medication switching. Baseline parameters and parameters changed 1 month after medication switching were compared between patients with GRA ≥ 1 and GRA < 1.Of the 282 enrolled patients (209 men, 73 women; mean age, 74.4 years), 55.3% had better (GRA ≥ 1), 31.2% had similar (GRA = 0), and 10.3% had worse (GRA < 0) outcomes. The overall adverse events (AE) rate decreased from 24.1% to 12.8%. In overall patients, there was no significant improvement of OAB symptoms, but postvoid residual (PVR) urine decreased and voiding symptoms and quality of life index improved significantly. Patients with GRA ≥ 1 had significantly improved both storage and voiding symptoms. A total of 195 patients (69.1%) can maintain mirabegron without adding or resuming antimuscarinics for more than 3 months. Logistic regression analysis indicated that higher baseline OAB symptoms scores were predictor of satisfactory outcome.More than 50% patients exhibited better outcomes after switching from antimuscarinics to mirabegron. Significantly lower AE rates and decreased PVR were noted. Higher baseline OAB symptom scores may predict a better outcome.

Abstract
There is an unmet need for treatment of erectile dysfunction resulting from radical prostatectomy and cavernous nerve (CN) injury. Given the neuroprotective properties of docosahexaenoic acid (DHA), we investigated its effect on penile functional and structural recovery in a rat model of bilateral cavernous nerve injury. Rats were subject to CN injury and received intraperitoneal administration of either vehicle or a DHA nanoemulsion (nano-DHA) at 10, 50, or 250 μg/kg. Functional testing and histological analyses were performed at 28 days post-injury. The maximum intracavernosal pressure (ICP) and other measures of erectile function were significantly higher in the nano-DHA groups than in the vehicle group (p < 0.05). The ratio of area of expression of neuronal nitric oxide synthase (nNOS)/β-III tubulin, numbers of axon and smooth muscle cell content were significantly higher in the 50 μg/kg nano-DHA group than in the vehicle group (p < 0.05). A qualitative increase in the smooth muscle cells/collagen ratio and decrease in apoptosis was observed in the nano-DHA groups relative to the vehicle group: however, these differences were not statistically significant. Our data demonstrate that nano-DHA, particularly the 50 μg/kg regimen, improves erectile function after bilateral CN injury in rats by neuroprotection and other anti-fibrotic and anti-apoptotic mechanisms.

Abstract
We investigated and evaluated the mechanisms of erectile dysfunction (ED) in a rat model of long-term ketamine administration. Adult male Sprague-Dawley rats (n = 32) were divided into four groups: namely the control group receiving intraperitoneal injection of saline, 1-month, 2-month and 3-month groups receiving daily intraperitoneal injection of ketamine (100 mg/kg/day) for 1, 2, and 3 month respectively. After treatment, animals underwent an erectile response protocol to assess intracavernosal pressure (ICP). Smooth muscle content was evaluated. Neuronal nitric oxide synthase (nNOS), inducible nitric oxide synthase (iNOS) and endothelial nitric oxide synthase (eNOS) expression were assessed using immunostaining assay. Ketamine-induced apoptosis was analyzed using TUNEL assay. Long-term ketamine administration caused significantly decreased erectile responses as measured by ICP. Smooth muscle content was significantly decreased in the ketamine-treated rats for 3 months. In the erectile tissue, ketamine administration significantly reduced nNOS expression and increased iNOS content compared with controls, whereas eNOS expression was not altered. Ketamine induced apoptosis in corpus cavernosum. The present study demonstrates that long-term ketamine administration led to erectile dysfunction in rat. The molecular mechanisms of ketamine-induced ED involved the increased apoptosis and up-regulated iNOS expression incorporating with loss of corporal smooth muscle content and reduced nNOS expression in cavernous nerve.

Abstract
OBJECTIVES Lower urinary tract symptoms (LUTS) in men result from a complex interplay of pathophysiology, including bladder and bladder outlet dysfunction. This study retrospectively analyzed bladder dysfunction in men with LUTS based on the results of video-urodynamic studies (VUDS). METHODS Male patients (aged ≥40 years), with LUTS and an International Prostate Symptom Score of 8 or more, who were refractory to alpha-blocker treatment were retrospectively recruited and evaluated with VUDS and total prostate volume (TPV). Patients were further divided into subgroups of bladder dysfunction and bladder outlet dysfunction according to characteristic VUDS findings. Age, TPV and VUDS findings were compared among different subgroups. RESULTS After VUDS, bladder outlet obstruction (BOO) was only noted in 48.6% of men. Of patients, 919 of 2991 (30.7%) had bladder dysfunction including detrusor underactivity (DU, 5.1%), detrusor overactivity and inadequate contractility (DHIC, 5.3%), detrusor overactivity (DO, 17%) and hypersensitive bladder (HSB, 3.3%). In addition, 1941 (64.9%) had bladder outlet dysfunction including BOO + DO (33.8%), BOO alone (14.8%), and poor urethral sphincter relaxation (PRES, 16.3%). Among the 1519 patients with DO, 66.6% (1012) had BOO while, among 1454 patients with BOO, 69.5% (1010) had DO. Patients with DHIC, DU and DO were 5 years older than patients with HSB and normal men. TPV was significantly smaller in patients with DHIC, DU and DO as compared with BOO + DO. CONCLUSION Approximately one-third of male LUTS was due to bladder dysfunction. A man older than 70 years with LUTS and TPV less than 30 mL usually indicates the presence of bladder dysfunction rather than BOO.

Abstract
Endothelial progenitor cells (EPCs) are bone marrow-derived endothelial cells capable of circulating, proliferating, and differentiating into mature endothelial cells. Circulating EPCs can be directly recruited to some extent at sites of injury, and their administration could accelerate repair or endothelialization of the damaged tissue. We investigated the effects of intracavernous injections of EPCs into the corpora cavernosa of rats with erectile dysfunction (ED) caused by bilateral cavernous nerve (CN) injury. Overall, 24 male Sprague-Dawley rats were randomized into three groups: sham surgery, vehicle-only, or EPC treatment. Rats in the EPC treatment and vehicle-only groups were subjected to bilateral CN injury before injection of EPCs or vehicle, respectively, into the corpora cavernosa. Four weeks after surgery, erectile function was assessed by measuring maximum intracavernosal pressure (ICP), change in ICP, area under the ICP curve, and ratio of change in ICP and mean arterial pressure (MAP; ΔICP/MAP). Penile tissue was histomorphometrically analyzed for the expression of neural nitric oxide synthase (nNOS), neurofilament-1 (NF-1), von Willebrand factor (vWF), endothelial NOS (eNOS), and smooth muscle cell content. Maximum ICP and all other functional parameters of erectile function were significantly reduced in the vehicle-only group vs. the sham and EPC treatment groups (all p < 0.001). Smooth muscle cell content was decreased in the vehicle-only vs. the sham and EPC treatment groups (both p < 0.01). Expressions of vWF and eNOS in the dorsal artery were significantly higher in the EPC treatment than the vehicle-only group (p < 0.05). In conclusion, EPC treatment restored erectile function in a rat model of bilateral CN injury through recruitment of EPCs toward the dorsal artery and preservation of smooth muscle cells in the corpus cavernosum. These findings elucidate the therapeutic potential of EPCs for treating ED in humans.

Abstract
This study aimed to examine this association by comparing the risk of prior irritable bowel syndrome (IBS) between patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and matched controls in Taiwan. Data were retrieved from the Longitudinal Health Insurance Database 2005. This study included 4870 cases with CP/CPPS and 4870 age-matched controls. Conditional logistic regressions were conducted to examine associations of CP/CPPS with previously diagnosed IBS. We found that a total of 753 (7.7%) of the 9740 sampled patients had IBS prior to the index date; IBS was found in 497 (10.2%) cases and in 256 (5.3%) controls. Conditional logistic regression revealed a higher odds ratio (OR) of prior IBS (OR 2.05, 95% CI = 1.75–2.40) for cases than controls. Furthermore, after adjusting for the patients’ monthly income, geographical location, urbanization level, and hypertension and coronary heart disease, the conditional logistic regression analysis indicated that cases were more likely than controls to have prior IBS (OR = 1.96, 95% CI = 1.67–2.29). Furthermore, we found that CP/CPPS was consistently and significantly associated with prior IBS regardless of age group. We concluded that the diagnosis of CP/CPPS was associated with previously diagnosed IBS. Urologists should be aware of the association between CP/CPPS and IBS when treating patients.

Impact of novel techniques on minimally invasive adrenal surgery: trends and outcomes from a contemporary international large series in urology. World J Urol 2016; 34:1473-9.

Abstract
OBJECTIVE To evaluate contemporary international trends in the implementation of minimally invasive adrenalectomy and to assess contemporary outcomes of different minimally invasive techniques performed at urologic centers worldwide. METHODS A retrospective multinational multicenter study of patients who underwent minimally invasive adrenalectomy from 2008 to 2013 at 14 urology institutions worldwide was included in the analysis. Cases were categorized based on the minimally invasive adrenalectomy technique: conventional laparoscopy (CL), robot-assisted laparoscopy (RAL), laparoendoscopic single-site surgery (LESS), and mini-laparoscopy (ML). The rates of the four treatment modalities were determined according to the year of surgery, and a regression analysis was performed for trends in all surgical modalities. RESULTS Overall, a total of 737 adrenalectomies were performed across participating institutions and included in this analysis: 337 CL (46 % of cases), 57 ML (8 %), 263 LESS (36 %), and 80 RA (11 %). Overall, 204 (28 %) operations were performed with a retroperitoneal approach. The overall number of adrenalectomies increased from 2008 to 2013 (p = 0.05). A transperitoneal approach was preferred in all but the ML group (p < 0.001). European centers mostly adopted CL and ML techniques, whereas those from Asia and South America reported the highest rate in LESS procedures, and RAL was adopted to larger extent in the USA. LESS had the fastest increase in utilization at 6 %/year. The rate of RAL procedures increased at slower rates (2.2 %/year), similar to ML (1.7 %/year). Limitations of this study are the retrospective design and the lack of a cost analysis. CONCLUSIONS Several minimally invasive surgical techniques for the management of adrenal masses are successfully implemented in urology institutions worldwide. CL and LESS seem to represent the most commonly adopted techniques, whereas ML and RAL are growing at a slower rate. All the MIS techniques can be safely and effectively performed for a variety of adrenal disease.
