RESUMEN
OBJECTIVE: To investigate the prevalence of frailty and its effects on cancer-related fatigue and quality of life among patients with prostate cancer. METHODS: In this cross-sectional study, questionnaires were administered to 254 outpatients who visited the Department of Urology at Kagawa University Hospital for prostate cancer; finally, 108 outpatients were analyzed. Frailty, cancer-related fatigue and quality of life were assessed using the G8 screening tool, Japanese version of the Brief Fatigue Inventory and Japanese version of the Short Form 8 Health Survey, respectively. We defined frailty based on a score ≤14 points and divided the patients into frailty and no-frailty groups. We also compared the severity of cancer-related fatigue and quality of life between groups. RESULTS: The prevalence of frailty among 108 outpatients was 63%. Older age correlated with frailty severity (P = 0.0007) but not cancer-related fatigue severity (P = 0.2391). The proportion of patients on treatment or with metastasis was not significantly different between groups. The frailty group had higher cancer-related fatigue severity (P = 0.004) and decreased levels of general activity, mood, walking ability, normal work and enjoyment of life, especially on the Brief Fatigue Inventory subscale. The frailty group had lower physical and mental quality of life than the no-frailty group or general population. CONCLUSIONS: The frailty rate for these patients increased with age, exceeding 60% regardless of the treatment status, and was associated with worsened cancer-related fatigue severity and reduced quality of life. Our study highlights the importance of assessing frailty when selecting treatment, especially in older patients.

BACKGROUND: Enfortumab vedotin is a novel antibody-drug conjugate used as a third-line therapy for the treatment of urothelial cancer. We aimed to elucidate the effect of enfortumab vedotin-related peripheral neuropathy on its efficacy and whether enfortumab vedotin-induced early electrophysiological changes could be associated with peripheral neuropathy onset. METHODS: Our prospective multicenter cohort study enrolled 34 patients with prior platinum-containing chemotherapy and programmed cell death protein 1/ligand 1 inhibitor-resistant advanced urothelial carcinoma and received enfortumab vedotin. The best overall response, progression-free survival, overall survival, and safety were assessed. Nerve conduction studies were also performed in 11 patients. RESULTS: The confirmed overall response rate and disease control rate were 52.9% and 73.5%, respectively. The median overall progression-free survival and overall survival were 6.9 and 13.5 months, respectively, during a median follow-up of 8.6 months. The patients with disease control had significantly longer treatment continuation and overall survival than did those with uncontrolled disease. Peripheral neuropathy occurred in 12.5% of the patients. The overall response and disease control rates were 83.3% and 100%, respectively: higher than those in patients without peripheral neuropathy (p = 0.028 and p = 0.029, respectively). Nerve conduction studies indicated that enfortumab vedotin reduced nerve conduction velocity more markedly in sensory nerves than in motor nerves and the lower limbs than in the upper limbs, with the sural nerve being the most affected in the patients who developed peripheral neuropathy (p = 0.011). CONCLUSION: Our results indicated the importance of focusing on enfortumab vedotin-induced neuropathy of the sural nerve to maximize efficacy and improve safety.

OBJECTIVES: To assess whether the coronavirus disease (COVID-19) pandemic affected the outcomes of robot-assisted radical prostatectomy (RARP) and urologists' treatment behaviors. METHODS: We retrospectively examined the medical records of 208 patients who had undergone RARP between August 2017 and December 2022. We compared the rate of preoperative androgen deprivation therapy (ADT), waiting period for RARP, patients' baseline characteristics and quality of life (QOL), proportion of adverse pathology on the RARP specimen, rate of Gleason grade group upgrading from biopsy to the RARP specimen, and prostate-specific antigen (PSA) recurrence-free survival between the pre-pandemic and pandemic groups. RESULTS: The rate of preoperative ADT was significantly higher during than before the COVID-19 pandemic (13.7% vs. 1.9%; p = 0.002). The baseline physical and mental QOL scores did not differ significantly between the groups. The proportion of D'Amico low-risk patients was significantly lower (13.6% vs. 1.2%, p = 0.005) and waiting period for RARP was significantly shorter (median 3.5 months vs. 4.0 months, p = 0.016) in the pandemic group than in the pre-pandemic group. There was no significant difference in the proportion of adverse pathology between the groups (p = 0.104); however, the upgrading rate was significantly higher in the pre-pandemic group (p = 0.002). There was no significant difference in PSA recurrence-free survival between the groups (log-rank, p = 0.752). CONCLUSIONS: The COVID-19 pandemic did not adversely affect the oncologic outcomes of RARP and QOL before RARP. However, it caused urologists to increase the use of preoperative ADT and to reserve RARP for higher-risk cases.

OBJECTIVE: this study aimed to evaluate the active surveillance continuation period, treatment intervention rate and health-related quality of life in younger patients. METHODS: we prospectively conducted a health-related quality of life survey of patients enrolled in the Prostate Cancer Research International: Active Surveillance-JAPAN study at Kagawa University between January 2010 and December 2020. Health-related quality of life was assessed by mail using a validated Japanese version of the Short-Form 8 Health Survey and Expanded Prostate Cancer Index at active surveillance enrolment and annually thereafter until discontinuation of active surveillance. We divided the patients into two groups, younger (aged <65 years) and older (aged ≥65 years), and compared the two groups. RESULTS: of the 84 patients, 22 were in the younger group. The active surveillance continuation period was shorter in the younger group than in the older group. The 3-year treatment intervention rate was higher in the younger group than in the older group. The majority of the reasons for definitive treatment were related to the protocol, which was similar in both groups (80 versus 76%). The sexual summary scores at active surveillance enrolment were higher in the younger group than in the older group. During active surveillance, the younger group and the older group showed no deterioration in all health-related quality of life scores compared with the scores at the enrolment of active surveillance. CONCLUSIONS: patient-reported health-related quality of life survey indicated that the health-related quality of life of younger Japanese patients was maintained over time during active surveillance, similar to that of older patients.

OBJECTIVE: To conduct a national questionnaire survey of Japanese urologists on active surveillance (AS) for low- and intermediate-risk prostate cancer (PCa). METHODS: A questionnaire was sent to 922 Japanese Urological Association Teaching Base Hospitals. The items included were years of experience as a urologist, sex, workplace, treatment equipment owned, specialty area of daily practice, specialty area of urological cancer, and six hypothetical cases of AS. The cases were categorized by the following Gleason scores: 3 + 3 low risk of PCa, 3 + 4 intermediate risk, and 4 + 3 intermediate risk, with or without comorbidities for each case. Comorbidities were defined as cardiovascular diseases or illnesses warranting anticoagulant therapy. RESULTS: Altogether, 1962 questionnaires were analyzed. Responses were almost equally distributed among all age groups. Workplaces included general hospitals (49.4%), university hospitals (40.3%), and cancer centers (4.2%). Percentages of proposed AS for low risk/no comorbidity, low risk/with comorbidity, intermediate-risk 3 + 4/no comorbidity, intermediate risk 3 + 4/with comorbidity, intermediate risk 4 + 3/no comorbidity, and intermediate risk 4 + 3/with comorbidity were 90.5%, 90%, 39.5%, 48.7%, 15%, and 22%, respectively. Analysis of the correspondents' backgrounds showed that the more the urologists' years of experience, the less they were to advise AS of low-risk patients. In the presence of comorbidities, urologists across all age groups tended to propose AS, even in the same Gleason grade group. Cancer center urologists recommended AS more often than their counterparts at general and university hospitals. CONCLUSIONS: Approximately 40% of urologists proposed AS for intermediate-risk cases, confirming that AS for intermediate-risk patients is being considered in Japan.

OBJECTIVE: This study conducted a national questionnaire survey of Japanese urologists from a treatment perspective for older patients with prostate cancer. METHODS: A questionnaire was distributed to 922 teaching hospitals of the Japanese Urological Association. Questionnaire items included years of urologist experience, gender, workplace, treatment equipment owned, daily specialty practice area, urological cancer specialty, treatment reference items for older adults, upper age limit for radical treatment, medication, and two hypothetical cases of Gleason grade group 2 prostate cancer with or without oligometastasis. RESULTS: In total, 1732 questionnaires were analyzed, with responses evenly distributed across all age groups. Workplaces included general hospitals (49.4%), university hospitals (40.3%), and cancer centers (4.2%). Performance status was the most frequently mentioned treatment-related item, followed by comorbidities and cognitive function. In addition, geriatric assessment was used by only 13.3% of respondents. No upper age limit was found for total prostatectomy, brachytherapy, and external beam radiation. Anti-androgens, androgen receptor-axis-targeted agents, chemotherapy, poly ADP ribose polymerase inhibitors, and immune-checkpoint inhibitors were selected by 6.8%, 35.6%, 47.3%, 89%, 62.8%, 24.7%, 41.9%, and 41.7% of the respondents, respectively. Response rates for administration of hormone therapy for hypothetical cases of Gleason grade group 2 prostate cancer with or without oligometastases were 96.8% and 61.2%, respectively. CONCLUSIONS: Less than 15% of urologists used geriatric assessments. Several responded that they would set age limits for highly invasive radical and systemic therapies.

BACKGROUND: The Paris System (TPS) for reporting urinary cytology differs from conventional systems (CS) in that it focuses on the diagnosis of high-grade urothelial carcinoma (HGUC). This study investigated the impact of TPS implementation on the diagnostic accuracy of HGUC by comparing it with our institutional CS. METHODS: A total of 649 patients who underwent transurethral resection of bladder tumor (TURBT) between January 2009 and December 2020 were included in this study. Our institution adopted TPS to report urinary cytology in February 2020. The diagnostic accuracy of HGUC in preoperative urinary cytology was compared with the presence or absence of HGUC in resected specimens of TURBT before and after TPS implementation. RESULTS: After implementing TPS in urinary cytology, 89 patients were reviewed and compared with 560 patients whose urinary cytology was diagnosed by CS. TPS and CS for detecting HGUC had 56.0% and 58.2% sensitivity, 97.8% and 91.2% specificity, and 93.3% and 87.9% positive predictive values, respectively. There were no significant differences between TPS and CS in terms of sensitivity, specificity, and positive predictive value for HGUC (P = 0.83, 0.21, 1.00). On the other hand, the negative predictive value for HGUC using TPS was 80.0%, which was significantly higher than that of CS (66.4%, P = 0.04) The multivariate logistic regression analysis indicated that not using TPS was one of the independent predictive factors associated with false-negative results for HGUC (odds ratio, 2.26; 95% confidence interval, 1.08-4.77; P = 0.03). CONCLUSION: In instances where urinary cytology is reported as negative for HGUC by TPS, there is a low probability of HGUC, indicating that TPS has a potential diagnostic benefit.

OBJECTIVE: To evaluate the efficacy and safety of intravesical KRP-116D, 50% dimethyl sulfoxide solution compared with placebo, in interstitial cystitis/bladder pain syndrome patients. METHODS: Japanese interstitial cystitis/bladder pain syndrome patients with an O'Leary-Sant Interstitial Cystitis Symptom Index score of ≥9, who exhibited the bladder-centric phenotype of interstitial cystitis/bladder pain syndrome diagnosed by cystoscopy and bladder-derived pain, were enrolled. Patients were allocated to receive either KRP-116D (n = 49) or placebo (n = 47). The study drug was intravesically administered every 2 weeks for 12 weeks. RESULTS: For the primary endpoint, the change in the mean O'Leary-Sant Interstitial Cystitis Symptom Index score from baseline to week 12 was -5.2 in the KRP-116D group and -3.4 in the placebo group. The estimated difference between the KRP-116D and placebo groups was -1.8 (95% confidence interval -3.3, -0.3; P = 0.0188). Statistically significant improvements for KRP-116D were also observed in the secondary endpoints including O'Leary-Sant Interstitial Cystitis Problem Index score, micturition episodes/24 h, voided volume/micturition, maximum voided volume/micturition, numerical rating scale score for bladder pain, and global response assessment score. The adverse drug reactions were mild to moderate, and manageable. CONCLUSIONS: This first randomized, double-blind, placebo-controlled trial shows that KRP-116D improves symptoms, voiding parameters, and global response assessment, compared with placebo, and has a well-tolerated safety profile in interstitial cystitis/bladder pain syndrome patients with the bladder-centric phenotype.

G protein-coupled receptor 87 (GPR87) is a newly deorphanized member of the cell surface molecule G protein-coupled receptor family. GPR signaling was shown to play a role in promotion of cell growth and survival, metastasis, and drug resistance. The overexpression of GPR87 has also been reported in many malignant tumors including bladder cancer. The aim of the present study is to examine the effect of silencing GPR87 expression with a replication-deficient recombinant adenoviral vector expressing short hairpin RNA targeting GPR87 (Ad-shGPR87) and to explore the underlying molecular mechanisms in bladder cancer cells. Six GPR87-expressing human bladder cancer cells, HT1197, HT1376, J82, RT112, TCCSUP and UMUC3, were used. Infection with Ad-shGPR87 effectively downregulated the GPR87 expression, and significantly reduced the percentage of viable cells in 4 of 6 cell lines as detected by an MTT assay. Significant inhibition on cell proliferation with Ad-shGPR87 was observed in the wild-type p53 bladder cancer cell lines (HT1197, RT112, TCCSUP and UMUC3), but not in the mutant p53 cells (HT1376 and J82). As represented by a wild-type p53 RT112 cell, Ad-shGPR87 infection significantly enhanced p53 and p21 expression and caused caspase-dependent apoptosis. Furthermore, the treatment with Ad-shGPR87 exerted a significant antitumor effect against the GPR87-expressing RT112 xenografts. GPR87 appeared to be a promising target for gene therapy, and Ad-shGPR87 had strong antitumor effects, specifically anti-proliferative and pro-apoptotic effects, against GPR87-expressing human bladder cancer cells.

OBJECTIVE: Laparoscopic adrenalectomy is generally performed by either a transperitoneal approach (TA) or a retroperitoneal approach (RA). However, the optimal selection criteria for each approach are unclear. We investigated the factors affecting the safety of laparoscopic adrenalectomy to evaluate the optimal criteria for each approach. PATIENTS AND METHODS: In total, 149 patients who underwent laparoscopic adrenalectomy from February 1994 to July 2013 were retrospectively analyzed. We performed TA for 75 tumors in 73 patients and RA for 78 tumors in 76 patients. Patient characteristics and operative outcomes were compared between the two groups. Furthermore, operative outcomes in patients with some surgical risks were specifically compared between the two approaches. RESULTS: Patient characteristics were similar between the two groups, although the patients in the RA group were significantly older than those in the TA group. Four patients with a large pheochromocytoma in the TA group had excessive blood loss and one of them was given blood transfusion. However, there was no difference in intraoperative blood loss (p = 0.091). The other serious adverse events were not observed. CONCLUSIONS: The present findings suggest that both RA and TA can be effective surgical strategies, with close attention to large pheochromocytoma to avoid excessive hemorrhage.

Introduction: Small tumors may be difficult to identify visually and require preoperative effort to locate. Recent advancements in mixed reality technology have improved surgical accuracy in various departments. Here, we present the application of mixed reality-assisted surgery and a guiding marker in the case of small retroperitoneal metastasis of uterine cancer. Case presentation: A 67-year-old female with a history of uterine cancer had a retroperitoneal metastasis in the lateroconal fascia near the right diaphragm, measuring 2 cm and infiltrating the peritoneum. We performed precise surgical planning using the preoperative mixed reality software "Holoeyes" on a head-mounted display called HoloLens2. Novel techniques, including ultrasonography-guided placement of a guiding marker and strategic port-site placement facilitated by HoloLens2, ensured accurate tumor identification and laparoscopic resection with minimal blood loss and no intraoperative complications. Conclusion: The use of mixed reality-assisted surgery and a guiding marker effectively enhanced the precision of retroperitoneal tumor resection.
RESUMEN
Introduction: There have been reports of surgery for residual ureteral tumors, most of them involved open surgeries. Herein, we report a case of retroperitoneal scopic left ureteral resection and partial cystectomy, performed by placing a fluorescent ureteral catheter in the residual ureter. Case presentation: A 79-year-old man was admitted to our hospital with a chief complaint of gross hematuria. He had undergone transperitoneal left radical nephrectomy due to angiomyolipoma 20 years ago. Computed tomography and Magnetic resonance imaging revealed a solid tumor in the left residual ureter. Retroperitoneal scopic residual ureterectomy has been performed. During the operation, a fluorescent ureteral catheter proved to be very helpful in detecting the ureter. Conclusion: A fluorescent ureteral catheter is considered to be a useful tool in laparoscopic surgery, especially in cases where identification of the ureter is expected to be difficult, such as the residual ureter in this case.
RESUMEN
The orphan GPR87 has recently been matched with its ligand LPA, which is a lipid mediator with multiple physiological functions, including cancer cell proliferation. This study aimed to clarify the role of GPR87 in urothelial carcinoma of the bladder. GPR87 expression was assessed in seven human bladder cancer cell lines. A replication-deficient recombinant adenoviral vector expressing shRNA targeting GPR87 (Ad-shGPR87), was constructed. Gene silencing was carried out using Ad-shGPR87. Immunohistochemical analysis was performed for transurethral resection of bladder tumor samples from 71 patients with non-muscle-invasive bladder cancer. We observed GPR87 expression in five of the seven cell lines, and silencing GPR87 gene expression significantly reduced cell viability. GPR87 expression was positive in 38 (54%) of 71 tumors. Ki-67 index was associated with positive GPR87 staining status (p < 0.0001). Patients with GPR87-positive tumors had shorter intravesical recurrence-free survival than those with GPR87-negative tumors (p = 0.010). Multivariate analysis revealed that GPR87 staining status was an independent prognostic parameter for intravesical recurrence (p = 0.041). Progression from non-muscle-invasive to muscle-invasive tumor was more frequently observed in patients with GPR87-positive tumors, although this trend did not reach statistical significance (p = 0.056). These results warrant further prospective studies to clarify the role of GPR87 expression in intravesical recurrence and progression in bladder cancer.

We report a case of primary mucosa-associated lymphoid tissue (MALT)-type lymphoma of the urinary bladder, which temporarily regressed after antibiotic therapy and progressed 1 year after the treatment. The patient was a 72-year-old female with a history of recurrent cystitis. She was referred to our hospital for microscopic hematuria. Urinalysis also showed microscopic pyuria and cystoscopy revealed an erythematous and edematous submucosal lesion in the right side wall of the bladder. She was diagnosed with acute cystitis and treated with antibiotics. Cystoscopy after 2 months was normal. However, she presented with macroscopic hematuria and fever 1 year after the treatment. Computed tomography (CT) scan showed a solitary mass measuring 25×40 mm above the right ureteric orifice and right hydronephrosis. Transurethral resection was performed, and the histopathological findings were consistent with MALT-type lymphoma. No evidence of lymphoma was found on positron emission tomography-CT scan and bone marrow biopsy, and she was diagnosed with primary MALT-type lymphoma of the bladder. She was successfully treated with a combination of rituximab and radiotherapy. Since MALT-type lymphoma of the bladder sometimes regresses temporarily after antibiotic therapy, it should be followed carefully.

BACKGROUND: The efficacy of photodynamic diagnosis using 5-aminolevulinic acid during transurethral resection of bladder tumors has been demonstrated, albeit with limited information regarding its side effects. This study aimed to clarify the impact of oral 5-aminolevulinic acid on perioperative nausea and vomiting (NV) for the first time in a real-world clinical practice setting. METHODS: Patients who underwent transurethral surgery at Kagawa University between April 2017 and March 2020 were included. Perioperative NV and antiemetic use status were prospectively assessed and compared between the patients who received oral 5-aminolevulinic acid and those who did not. Additionally, univariate and multivariate analyses were performed for predicting postoperative nausea and vomiting. RESULTS: Of 214 patients, 74 (34.6%) received oral 5-aminolevulinic acid preoperatively. The proportions of preoperative NV and antiemetic use in the patients who received 5-aminolevulinic acid were 9.5% and 4.1%, respectively, and higher than in those who did not (0% and 0%; P < 0.01 and P = 0.04, respectively). Postoperative NV (25.7%) and antiemetics use (8.0%) ratios in the patients who received 5-aminolevulinic acid were significantly different from those in the non-users group (3.6% and 2.1%, P < 0.01 and P < 0.01, respectively). Although no differences in risk factors were found for postoperative NV between the two groups, multivariate analyses indicated 5-aminolevulinic acid use as an independent predictive factor for postoperative NV (odds ratio, 11.5; 95% confidence interval, 3.98-33.3; P < 0.01). CONCLUSIONS: Our study clearly showed that oral administration of 5-aminolevulinic acid was associated with perioperative NV even without risk factors, highlighting the need for addressing its application.

BACKGROUND: 5-aminolevulinic acid is a protoporphyrin IX precursor used for photodynamic diagnosis. We aimed to clarify the therapeutic benefits of orally administered 5-aminolevulinic acid for photodynamic diagnosis in transurethral resection for non-muscle-invasive bladder cancer in a real-world setting. METHODS: From January 2009 to December 2020, patients with non-muscle-invasive bladder cancer who have undergone visually complete resection by initial transurethral surgery were included. Histopathologically confirmed residual and intravesical recurrent bladder cancer was retrospectively investigated and compared with transurethral resection using photodynamic diagnosis and conventional white light. RESULTS: One hundred and fifteen patients who underwent photodynamic diagnosis-transurethral resection were compared with 346 patients who underwent white light-transurethral resection. The second transurethral resection revealed that the proportion of residual T1 and Ta bladder cancer was lower in the photodynamic diagnosis group than in the white light group (10.3% vs. 33.8%, P = 0.001). Additionally, the proportion of intravesical recurrence was lower in the photodynamic diagnosis group than in the white light group (9.6% vs. 41.9%, P < 0.001). Using 5-aminolevulinic acid-photodynamic diagnosis during transurethral resection of bladder tumor improved the cumulative intravesical recurrence-free survival (log-rank test: P < 0.001). Furthermore, multivariate analyses indicated that not using 5-aminolevulinic acid-photodynamic diagnosis was an independent predictive factor for residual bladder cancer (odds ratio, 6.16; 95% confidence interval, 2.10-18.0; P < 0.001) and intravesical recurrence (hazard ratio, 2.01; 95% confidence interval, 1.05-3.83, P = 0.034). CONCLUSIONS: Introducing 5-aminolevulinic acid-photodynamic diagnosis into transurethral resection reduces residual bladder cancer and improves the cumulative intravesical recurrence-free survival in patients with non-muscle-invasive bladder cancer, indicating its possible therapeutic benefits.

OBJECTIVES: To investigate the impact of age on the relationship between obstructive sleep apnea syndrome (OSAS), nocturia, and other lower urinary tract symptoms (LUTSs). METHODS: This was a secondary analysis study based on data derived from a previously conducted prospective observational cohort study on OSAS and nocturia. We analyzed 90 subjects who were suspected of having OSAS. Prior to polysomnography, we assessed International Prostate Symptom Score-Quality of Life scores, Overactive Bladder Symptom Scores, and International Consultation on Incontinence Modular Questionnaire-Nocturia Quality of Life scores to evaluate LUTSs. Nocturnal urine volume, night-time frequency, and night-time urine electrolyte content were measured during polysomnography. Patients were divided into groups according to age and OSAS severity determined using apnea-hypopnea index (AHI) scores. Young patients were those aged <65 years and elderly patients, ≥65 years. A multiple linear regression with multiple imputations was performed to examine the association of night-time frequency with demographic, polysomnographic, and clinical characteristics. RESULTS: In young patients, night-time frequency was significantly associated with nocturnal urine volume, AHI score, and total IPSS. However, night-time frequency in elderly subjects was not associated with demographic and polysomnographic characteristics. In order to compare the severity of OSAS, night-time frequency and urinary sodium content significantly increased only in young patients (P = .007 and .004, respectively). CONCLUSION: OSAS is a strong candidate of causative factor for nocturia in younger individuals. When a younger patient complains nocturia without any urological disorders, OSAS should be kept in mind as a potential cause of nocturia.

Lysophosphatidic acid (LPA) may enhance diverse biologic activities in prostate cancer. This study was conducted to analyze expression levels of LPA-producing enzymes, autotaxin (ATX) and acylglycerol kinase (AGK), in prostate cancer with relevance to clinicopathological parameters. Real-time RT-PCR and western blotting were performed for ATX and AGK in non-neoplastic prostate cells (PrECs and PrSCs) and prostate cancer cell-lines (DU-145, PC-3, LNCaP, and AILNCaP). Immunohistochemical analyses were conducted in tissue specimens of 132 localized prostate cancer patients who underwent radical prostatectomy between 2001 and 2007 (median observation period, 22 months). Both enzymes were negatively expressed in PrECs and PrSCs at mRNA and protein levels. ATX expression was higher than AGK in AILNCaP, DU-145, and PC-3 cell-lines, while AGK was mainly expressed in LNCaP cells. Immunohistochemically, ATX and AGK expressions were negative in non-neoplastic epithelia, while both were weakly expressed in the majority of high-grade intra-epithelial neoplasia (HG-PIN). In cancer foci, ATX and AGK expressions were strong in 49% and 62%, weak in 40% and 32%, and negative in 11% and 6%, respectively. Expressions of both enzymes were significantly correlated with primary Gleason grade of cancer foci (P < 0.0001) and capsular invasion (P = 0.03 and 0.003 respectively). ATX expression was significantly correlated with probability of prostate specific antigen (PSA)-failure after surgery (P < 0.0001). In conclusion, LPA-producing enzymes (ATX and AGK) were frequently expressed in prostate cancer cells and precancerous HG-PIN. In particular, high expression levels of ATX were associated with both malignant potentials and poor outcomes.

The lower urinary tract anatomy in men after radical prostatectomy (RP) resembles that in women. Out of 112 male patients who had undergone RP for localized prostate cancer, 102 (91%) of them responded to a questionnaire survey. The mean age of the responders at the time of RP was 65.9 +/- 5.3 years. The time of response after RP ranged from 2 months to 6 years (median: 44 months). The instruments used for the assessment of urinary status were the International Prostate Symptom Score (IPSS) and QOL score, the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and Overactive Bladder Symptom Score (OABSS). Urinary status of 40 elderly female patients aged 59.5 +/- 6.9 years who consulted our outpatient clinic due to conditions (microhematuria, simple renal cyst, etc.) unrelated to lower urinary tract disorders were assessed with the IPSS. In the male patients, total IPSS and QOL score showed significant improvement over time after RP (P = 0.0004, P = 0.0015, respectively). In particular, the voiding symptom score of IPSS showed significant improvement (P < 0.0001). The improvement of incontinence within 1 year after RP was confirmed with ICIQ-SF (p = 0.06). In contrast, the storage symptom score of IPSS after RP was not different with time after RP. Furthermore, the OABSS rose with time after RP (p = 0.08). On the other hand, in the elderly female controls, the storage symptom score of IPSS was significantly higher than voiding symptom score (P = 0.0019). Men who underwent RP showed significant improvement in their voiding symptoms and continence status, but the storage symptoms, progressively worsened following RP. Consequently, careful follow-up and appropriate medical intervention are needed in men after RP as in aging women.

A temporary inferior vena cava (IVC) filter was placed in 4 patients. Patient 1 had an advanced testicular germ cell tumor with IVC tumor thrombosis, patient 2 presented with a large adrenal tumor with IVC tumor thrombosis, patient 3 was found to have deep vein thrombosis following grade 3b renal injury, and patient 4 was suffering severe SLE with renal vein thrombosis. The temporary inferior vena cava filter prevented pulmonary thromboembolism in all cases, and no adverse reaction was observed. Temporary inferior vena cava filter is safe and useful to prevent pulmonary thromboembolism associated with urological disorders.
