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.

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.

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.

The purpose of this study was to determine whether contemporary active surveillance (AS) protocols could sufficiently discriminate significant from indolent tumors in men with low-risk prostate cancer. We retrospectively analyzed 312 patients with low-risk prostate cancer treated with radical prostatectomy. After exclusion of patients with fewer than 10 cores taken at biopsy and those who received neo-adjuvant treatment, 205 subjects satisfied the final inclusion criteria. Five widely accepted AS protocols were employed in this study. A total of 82.0% of the patients met the inclusion criteria of at least one protocol, and 18% did not meet any criteria of published AS protocols. A significant proportion of patients had non-organ-confined disease (8.6% to 10.6%) or a Gleason score of 7 or greater (18.6% to 23.9%) between the different AS criteria. Among patients who did not meet any AS criteria, 32.4% of patients had a pathologically insignificant cancer. Our results indicated a significant adverse pathology in patients who met the contemporary AS protocols. On the other hand, some patients in whom expectant management would be appropriate did not meet any criteria of published AS protocols. None of the clinical or histological criteria reported to date is able to sufficiently discriminate aggressive tumors from indolent ones.

PURPOSE: To evaluate the association of self-reported erectile function and endothelial function using the EndoPAT device. MATERIALS AND METHODS: We prospectively enrolled 76 men (age> or =40 years) after obtaining a complete medical history and a self-reported questionnaire (International Index of Erectile Function-5 [IIEF-5], SEP Q2, Q3). Endothelial function was noninvasively measured with an EndoPAT 2000, recorded as the reactive hyperemia index (RHI), and analyzed according to the patients' baseline characteristics. RESULTS: The mean patient age and IIEF-5 score were 62.50+/-8.56 years and 11.20+/-6.36, respectively. In comparing the RHI according to erectile dysfunction (ED) risk factors, the RHI was significantly lower in older subjects (p=0.004). There was no difference in the RHI according to age, body mass index, waist circumference, obesity, smoking habit, or other comorbidities. When the subjects were divided into four groups according to the severity of ED, no statistical differences in the RHI value were found among the groups. There was no difference in IIEF-5 according to the RHI when categorized according to the normal cutoff value or quartile ranges. The second subdomain of IIEF-5 (erection firmness) was significantly correlated with the RHI value (R=0.309, p=0.007); however, this was not the case with the other IIEF-5 subdomains. Self-assessment showed a tendency toward a negative correlation with the RHI value (R=-0.202, p=0.080). CONCLUSIONS: The role of endothelial function measurement by the EndoPAT in the evaluation and management of ED patients remains inconclusive. However, further studies are needed to validate the role of endothelial function measurement, by the EndoPAT or any other device.

PURPOSE: Complications after prostate biopsy have increased and various causes have been reported. Growing evidence of increasing quinolone resistance is of particular concern. In the current retrospective study, we evaluated the incidence of infectious complications after prostate biopsy and identified the risk factors. MATERIALS AND METHODS: The study population included 1,195 patients who underwent a prostate biopsy between January 2007 and December 2012 at Chung-Ang University Hospital. Cases of febrile UTI that occurred within 7 days were investigated. Clinical information included age, prostate-specific antigen, prostate volume, hypertension, diabetes, body mass index, and biopsy done in the quinolone-resistance era. Patients received quinolone (250 mg intravenously) before and after the procedure, and quinolone (250 mg) was orally administered twice daily for 3 days. We used univariate and multivariate analysis to investigate the predictive factors for febrile UTI. RESULTS: Febrile UTI developed in 39 cases (3.1%). Core numbers increased from 2007 (8 cores) to 2012 (12 cores) and quinolone-resistant bacteria began to appear in 2010 (quinolone-resistance era). In the univariate analysis, core number> or =12 (p=0.024), body mass index (BMI)>25 kg/m2 (p=0.004), and biopsy done in the quinolone-resistance era (p=0.014) were significant factors. However, in the multivariate analysis adjusted for core number, the results were not significant, with the exception of BMI>25 kg/m2 (p=0.011) and biopsy during the quinolone-resistance era (p=0.035), which were significantly associated with febrile UTI. CONCLUSIONS: Quinolone resistance is the main cause of postbiopsy infections in our center. We suggest that further evaluation is required to validate similar trends. Novel strategies to find alternative prophylactic agents are also necessary.

Despite the wide application of prostate-specific antigen-based screening leading to a profound stage migration in prostate cancer (PC), a significant percentage of men are still being diagnosed with clinically high-risk disease that requires aggressive treatment. Optimal management in these patients remains challenging, and strong advocates for radical prostatectomy (RP), radiotherapy, androgen deprivation therapy, and, increasingly, a multimodal approach abound. Currently, surgery for high-risk PC is frequently applied. RP offers an attractive opportunity for tumor excision either as a definitive management or as a first step in multimodal therapy. Nevertheless, this approach is still controversial. In this review, we discuss the current evidence for the role of RP in this clinical setting, including surgical considerations and outcomes. The role of robot-assisted RP, which is increasingly utilized in Korea in this clinical scenario, is discussed.

We found an error in our published article.

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.
