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.

A 61-year-old man presented with a right renal mass with a vena caval thrombus on computed tomography that was consistent with renal cell carcinoma. The results of routine laboratory examinations and urinalysis were within normal limits. Preoperative planning was critical owing to the presence of the vena caval thrombus. A radical nephrectomy, vena caval thrombectomy, and regional lymphadenectomy were done. The pathologic report was consistent with a high-grade, invasive urothelial carcinoma, with sarcomatoid differentiation involving the renal vein and inferior vena cava (Stage IV, T4N0M0). Thus, this was a rare case of upper tract urothelial carcinoma. Adjuvant chemotherapy with the methotrexate, vinblastine, doxorubicin, cisplatinum regimen is scheduled. To our knowledge, this is the first report in Korea of upper tract urothelial carcinoma of the sarcomatoid type with a vena caval thrombus.

PURPOSE: To evaluate the efficacy of low-dose computed tomography (LDCT) for detecting urinary stones with the use of an iterative reconstruction technique for reducing radiation dose and image noise. MATERIALS AND METHODS: A total of 101 stones from 69 patients who underwent both conventional nonenhanced computed tomography (CCT) and LDCT were analyzed. Interpretations were made of the two scans according to stone characteristics (size, volume, location, Hounsfield unit [HU], and skin-to-stone distance [SSD]) and radiation dose by dose-length product (DLP), effective dose (ED), and image noise. Diagnostic performance for detecting urinary stones was assessed by statistical evaluation. RESULTS: No statistical differences were found in stone characteristics between the two scans. The average DLP and ED were 384.60+/-132.15 mGy and 5.77+/-1.98 mSv in CCT and 90.08+/-31.80 mGy and 1.34+/-0.48 mSv in LDCT, respectively. The dose reduction rate of LDCT was nearly 77% for both DLP and ED (p<0.01). The mean objective noise (standard deviation) from three different areas was 23.0+/-2.5 in CCT and 29.2+/-3.1 in LDCT with a significant difference (p<0.05); the slight increase was 21.2%. For stones located throughout the kidney and ureter, the sensitivity and specificity of LDCT remained 96.0% and 100%, with positive and negative predictive values of 100% and 96.2%, respectively. CONCLUSIONS: LDCT showed significant radiation reduction while maintaining high image quality. It is an attractive option in the diagnosis of urinary stones.

PURPOSE: The aim of this study was to evaluate the effectiveness of simultaneous flexible ureteroscopic removal of stones (URS) for ureteral and ipsilateral renal stones and to analyze the predictive factors for renal stone-free status. MATERIALS AND METHODS: We retrospectively reviewed the records of patients who underwent simultaneous flexible URS of ureteral and ipsilateral renal stones from January 2010 to May 2012. All operations used a flexible ureteroscope. We identified 74 cases of retrograde intrarenal surgery and 74 ureteral stones (74 patients). Stone-free status was respectively defined as no visible stones and clinically insignificant residual stones <3 mm on a postoperative image study. Predictive factors for stone-free status were evaluated. RESULTS: The immediate postoperative renal stone-free rate was 70%, which increased to 83% at 1 month after surgery. The immediate postoperative ureteral stone-free rate was 100%. Among all renal stones, 15 (20.3%) were separately located in the renal pelvis, 11 (14.8%) in the upper calyx, 15 (20.3%) in the mid calyx, and 33 (44.6%) in the lower calyx. The mean cumulative stone burden was 92.22+/-105.75 mm2. In a multivariate analysis, cumulative stone burden <100 mm2 was a significant predictive factor for postoperative renal stone-free status after 1 month (p<0.01). CONCLUSIONS: Flexible URS can be considered simultaneously for both ureteral and renal stones in selected patients. Flexible URS is a favorable option that promises high stone-free status without significant complications for patients with a stone burden <100 mm2.

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.
