1.Pain, Catastrophizing, and Depression in Chronic Prostatitis/Chronic Pelvic Pain Syndrome.
International Neurourology Journal 2013;17(2):48-58
Persistent and disabling pain is the hallmark of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). However, disease severity (as measured by objective indexes such as those that use radiography or serology) is only marginally related to patients' reports of pain severity, and pain-related presentation can differ widely among individuals with CP/CPPS. Increasing evidence in support of the biopsychosocial model of pain suggests that cognitive and emotional processes are crucial contributors to inter-individual differences in the perception and impact of pain. This review describes the growing body of literature relating depression and catastrophizing to the experience of pain and pain-related sequelae in CP/CPPS. Depression and catastrophizing are consistently associated with the reported severity of pain, sensitivity to pain, physical disability, poor treatment outcomes, and inflammatory disease activity and potentially with early mortality. A variety of pathways, from cognitive to behavioral to neurophysiological, seem to mediate these deleterious effects. Collectively, depression and catastrophizing are critically important variables in understanding the experience of pain in patients with CP/CPPS. Pain, depression, and catastrophizing might all be uniquely important therapeutic targets in the multimodal management of a range of such conditions.

2.Laparoscopic Adrenalectomy in Urology.
Korean Journal of Urological Oncology 2015;13(1):17-23
Laparoscopic adrenalectomy has been the standard method for resecting adrenal gland tumors. Recently, laparoscopic retroperitoneal adrenalectomy (RA) has been more popular than conventional transperitoneal laparoscopic adrenalectomy (TLA) as an alternative method. Studies comparing laparoscopic RA and TLA showed that laparoscopic RA was superior or at least comparable to TLA in operation time, blood loss, pain score, hospital stay, and return to normal activity. Conversion rates and complication rates were similar. At present, laparoscopic RA has been int the limelight procedure for patients with benign adrenal disease. However, surgeons have been reluctant to offer this operation to patients because of the concerns over inadequate working space and overall perceived higher rate of complications, laparoscopic RA is not popular in urologic field up to now. This article summarizes the latest ideas and issues on laparoscopic RA in the expanding field of laparoscopy in urology.

PURPOSE: The aim of this study was to investigate the changes in the clinical and prognostic parameters of prostate cancer in Korean men in the eras before and after prostate-specific antigen (PSA) testing. MATERIALS AND METHODS: The medical records of 303 patients treated for prostate cancer between 1982 and 2005 were reviewed with respect to age, chief complaints, clinical stage, tumor grade, treatment options, and prognosis. We classified the patients as follows: those treated in the pre-PSA era (1982-1995, n=81), and those treated in the PSA era (1996-2000, PSA era phase 1, n=92; and 2001-2005, PSA era phase 2, n=130). RESULTS: There was no significant difference in age or clinical stage between patients treated before and those treated during the PSA era, although there was a downward migration of grade. The cancer-specific survival rates were also not different in all cases and in metastatic prostate cancer cases between the pre-PSA era and the PSA era, although the overall survival rates were significantly greater in all cases in phase 2 of the PSA era than in the pre-PSA era or in phase 1 of the PSA era (p<0.05). However, the cancer-specific survival rates for localized or locally advanced prostate cancer were significantly greater in phase 2 of the PSA era than in the pre-PSA era or in phase 1 of the PSA era (p<0.05). CONCLUSIONS: We observed a downward migration of tumor grade, but there were no migrations in the age of patients or clinical stage, and these findings have not contributed to changes in the cancer survival of Korean men with prostate cancer after the advent of PSA testing.

Korean Journal of Urological Oncology 2019;17(3):143-149
PURPOSE:
We evaluated the impact of bladder neck stiffness on lower urinary tract symptoms in the patient with benign prostatic hyperplasia using elastography.
MATERIALS AND METHODS:
A total of 384 patients divided into three different groups according to the bladder neck stiffness based on ultrasound with elastography. Patients age, prostate specific antigen (PSA), International Prostate Symptom Score (IPSS), prostate volumetric parameters, residual urine volume, and laboratory data were collected and compared among the three groups.
RESULTS:
Group 1 (n=121) showed low stiffness in both bladder neck adenoma. Group 2 (n=157) showed low to intermediated stiffness, and group 3 (n=106) showed significantly higher stiffness of bladder neck and adenoma compared to adjacent prostatic tissue. Significant differences among the 3 groups were found in the total prostate volume, transition zone volume, transition zone index, total IPSS, IPSS-voiding, IPSS-storage, residual urine volume, and quality of life. As the stiffness increased, prostate volumetric parameters, and residual urine volume were increased, and lower urinary tract symptoms became exacerbated. No significant difference was found in the patients' age and PSA.
CONCLUSIONS
Bladder neck stiffness affected the lower urinary tract symptoms and prostate volumetric parameters. These findings suggest that the change of bladder neck stiffness can be a novel parameter for the development of lower urinary tract symptoms/benign prostate hyperplasia.

We investigated how the dual inhibition of the molecular mechanism of the mammalian target of the rapamycin (mTOR) downstreams, P70S6 kinase (P70S6K) and eukaryotic initiation factor 4E (eIF4E), can lead to a suppression of the proliferation and progression of urothelial carcinoma (UC) in an orthotopic mouse non-muscle invasive bladder tumor (NMIBT) model. A KU-7-luc cell intravesically instilled orthotopic mouse NMIBC model was monitored using bioluminescence imaging (BLI) in vivo by interfering with different molecular components using rapamycin and siRNA technology. We then analyzed the effects on molecular activation status, cell growth, proliferation, and progression. A high concentration of rapamycin (10 microM) blocked both P70S6K and elF4E phosphorylation and inhibited cell proliferation in the KU-7-luc cells. It also reduced cell viability and proliferation more than the transfection of siRNA against p70S6K or elF4E. The groups with dual p70S6K and elF4E siRNA, and rapamycin reduced tumor volume and lamina propria invasion more than the groups with p70S6K or elF4E siRNA instillation, although all groups reduced photon density compared to the control. These findings suggest that both the mTOR pathway downstream of eIF4E and p70S6K can be successfully inhibited by high dose rapamycin only, and p70S6K and Elf4E dual inhibition is essential to control bladder tumor growth and progression.

PURPOSE: Experimental studies have suggested that the stromal-derived factor-1 (SDF-1)/CXCR4 axis is associated with tumor aggressiveness and metastasis in several malignancies. We performed a meta-analysis to elucidate the relationship between CXCR4 expression and the clinicopathological features of prostate cancer. MATERIALS AND METHODS: Data were collected from studies comparing Gleason score, T stage, and the presence of metastasis with CXCR4 levels in human prostate cancer samples. The studies were pooled, and the odds ratio (OR) of CXCR4 expression for clinical and pathological variables was calculated. RESULTS: Five articles were eligible for the current meta-analysis. We found no relationship between CXCR4 expression and Gleason score (<7 vs. > or =7). The forest plot using the fixed-effects model indicated an OR of 1.585 (95% confidence interval [CI]: 0.793~3.171; p=0.193). Further, CXCR4 expression was not associated with the T stage (

This study aimed to investigate the overall cumulative exposure-response and the lag response relationships between daily temperature and urolithiasis presentation in Seoul. Using a time-series design and distributing lag nonlinear methods, we estimated the relative risk (RR) of urolithiasis presentation associated with mean daily temperature, including the cumulative RR for a 20 days period, and RR for individual daily lag through 20 days. We analyzed data from 14,518 patients of 4 hospitals emergency department who sought medical evaluation or treatment of urolithiasis from 2005-2013 in Seoul. RR was estimated according to sex and age. Associations between mean daily temperature and urolithiasis presentation were not monotonic. Furthermore, there was variation in the exposure-response curve shapes and the strength of association at different temperatures, although in most cases RRs increased for temperatures above the 13℃ reference value. The RRs for urolothiasis at 29℃ vs. 13℃ were 2.54 in all patients (95% confidence interval [CI]: 1.67-3.87), 2.59 in male (95% CI, 1.56-4.32), 2.42 in female (95% CI, 1.15-5.07), 3.83 in male less than 40 years old (95% CI, 1.78-8.26), and 2.47 in male between 40 and 60 years old (95% CI, 1.15-5.34). Consistent trends of increasing RR of urolithiasis presentation were observed within 5 days of high temperatures across all groups. Urolithiasis presentation increased with high temperature with higher daily mean temperatures, with the strongest associations estimated for lags of only a few days, in Seoul, a metropolitan city in Korea.

We established an orthotopic non-muscle invasive bladder cancer (NMIBC) mouse model expressing the mammalian target of the rapamycin (mTOR) signaling pathway. After intravesical instillation of KU-7-lucs (day 0), animals were subsequently monitored by bioluminescence imaging (BLI) on days 4, 7, 14, and 21, and performed histopathological examination. We also validated the orthotopic mouse model expressing the mTOR signaling pathway immunohistochemically. In vitro BLI photon density was correlated with KU-7-luc cell number (r2 = 0.97, P < 0.01) and in vivo BLI photon densities increased steadily with time after intravesical instillation. The tumor take rate was 84.2%, formed initially on day 4 and remained NMIBC up to day 21. T1 photon densities were significantly higher than Ta (P < 0.01), and histological tumor volume was positively correlated with BLI photon density (r2 = 0.87, P < 0.01). The mTOR signaling pathway-related proteins were expressed in the bladder, and were correlated with the western blot results. Our results suggest successful establishment of an orthotopic mouse NMIBC model expressing the mTOR signaling pathway using KU-7-luc cells. This model is expected to be helpful to evaluate preclinical testing of intravesical therapy based on the mTOR signaling pathway against NMIBC.
