Dysgeusia in patients with advanced urothelial carcinoma receiving enfortumab vedotin, platinum-based chemotherapy, or immune check point inhibitors: time-course assessment using chemotherapy-induced taste alteration scale.

A time-course questionnaire survey using the chemotherapy-induced taste alteration scale (CiTAS) was conducted in patients with advanced urothelial carcinoma (UC) treated with systemic chemotherapy and/or immunotherapy. A total of 37 patients receiving systemic therapy with enfortumab vedotin (EV), platinum-based chemotherapy and immune checkpoint inhibitors were included in this study. No significant changes were observed in any of the CiTAS subscales during platinum-based chemotherapy and immune checkpoint inhibitor treatment, while EV therapy induced significant dysgeusia. Among 10 patients treated with EV, dysgeusia was associated with a substantial negative effect on the health-related quality-of-life domains, particularly global health status/QOL (mean ± standard deviation: 52 ± 19 in dysgeusia group vs 89 ± 13 in non-dysgeusia group) and mental component summary (47 ± 5.1 vs 53 ± 2.0). The fatigue symptom score was higher in the dysgeusia group at the post-third cycle of EV (47 ± 16 vs 15 ± 17). Severe dysgeusia can be induced by EV therapy, which is usually not observed in other systemic therapies for advanced UC.

Electroencephalography-based investigation of the effects of oral desmopressin on improving slow-wave sleep time in nocturnal polyuria patients (the DISTINCT study): A single-arm, open-label, single-assignment trial.

AIMS: To investigate changes in subjective and objective sleep quality after desmopressin administration in patients with nocturia due to nocturnal polyuria (NP) using electroencephalography (EEG) and the Pittsburgh sleep quality index (PSQI). METHODS: Twenty male patients (≥65 years old) with NP participated in this study. The inclusion criteria were nocturnal frequency ≥ 2, NP index (NPi) ≥ 0.33, first uninterrupted sleep period (FUSP) ≤ 2.5 h, serum sodium concentration ≥ 135 mEq/L, and estimated glomerular filtration rate ≥ 50 mL/min/1.73 m2. Participants were given 50 µg of desmopressin to be taken orally once daily before bed. The primary endpoint was the change in the duration of slow-wave sleep (nonrapid eye movement sleep stages 3 and 4), as evaluated by EEG 28 days from the baseline. The visual analog scale (VAS) was used as an additional indicator of sleep quality. RESULTS: Analysis of data from 15 participants (median age: 74.0 [70.5, 76.0] years) revealed that from before to after desmopressin administration, significant decreases occurred in the median nocturnal frequency (3.0 [2.0, 4.0] to 1.5 [1.0, 2.0]) and NPi (0.445 [0.380, 0.475] to 0.360 [0.250, 0.430]). Furthermore, FUSP was significantly prolonged from 120.0 (94.0, 150.0) min to 210.0 (203.8, 311.3) min. Although the VAS scores improved, slow-wave sleep duration and the PSQI global score showed no significant differences (68.50 [47.50, 75.50] and 48.00 [38.00, 66.50]; 5.0 [5.0, 10.0] and 7.0 [5.0, 9.0] min, respectively). CONCLUSION: Oral administration of 50 µg desmopressin improved nocturnal frequency and FUSP in older individuals with NP but did not significantly enhance sleep quality. In older adults, decreased nighttime urinary frequency may enhance quality of life; however, its influence on objective sleep quality may be limited.

Trisomy 13 with retroiliac ureter diagnosed by assessment for recurrent febrile urinary tract infections.

Introduction: Patients with trisomy 13 have multiple malformations, including urological anomalies, and severe cognitive and psychomotor disabilities. We conducted a ureteroureterostomy for a mid-ureteral stricture due to a retroiliac ureter in a patient with trisomy 13. Case presentation: A 6-month-old girl with trisomy 13 developed a urinary tract infection. Computed tomography for assessing recurrent urinary tract infection revealed a left mid-ureteral stricture due to the retroiliac ureter. At the age of 2, a ureteroureterostomy was performed. Two years after surgery, the urinary tract infection did not recur. Conclusion: Ureteroureterostomy is a safe procedure for children with trisomy 13 and multiple comorbidities. Surgical treatment should be considered for patients with trisomy 13 when agreed upon by the family and comorbidities are well-controlled.

Post-Disaster Community Transition of Psychiatric Inpatients: Lessons from the Fukushima Nuclear Accident.

This study sought to explore factors related to community transition after the mandatory evacuation of psychiatric inpatients to other hospitals owing to the Fukushima Daiichi Nuclear Power Plant accident. A retrospective cohort design was adopted and 391 psychiatric patients were examined. Univariate and multivariate analyses were conducted to confirm the association between the achievement or non-achievement of discharge to community living and their backgrounds (age, gender, evacuation destination, psychiatric diagnoses, and physical complications). Multivariate analysis indicated that patients with psychiatric diagnoses of schizophrenia, schizotypal, and delusional disorders (International Statistical Classification of Diseases and Related Health Problems 10th revision, F20-29), and those with physical diagnoses of the circulatory (I00-95) and digestive (K00-93) systems showed a significant association with the non-attainment of community transition. From these results, we hypothesized that difficulties in the management of medication during and immediately after the extremely chaotic settings of evacuation could have negative effects on the community transitions. Furthermore, another possible concern was that individuals' persistent psychotic status before the accident had been carried over to the destination hospitals. Therefore, pre-disaster daily cooperation across hospitals and challenges for vulnerable psychiatric patients' future community lives are also essential.

Long-term follow-up of congenital hydronephrosis in a single-center study.

OBJECTIVES: Many congenital hydronephroses spontaneously resolve. This study evaluated a long-term follow-up of more than 4 years of patients with congenital hydronephrosis at a single center. METHODS: In total, 215 patients (286 kidneys) with congenital hydronephrosis were included. Hydronephrosis outcomes (resolution, improvement, and persistence) and time-to-outcome were evaluated. RESULTS: Fourteen patients underwent early surgical intervention until the age of 2 years. A total of 189 congenital hydronephrosis cases (66%) showed resolution at a median of 16 months (interquartile range: 7-21 months) and 169 (80%) of 210 kidneys with grade I to II hydronephrosis showed resolution at a median of 14 months (interquartile range: 6-23 months). Of 76 kidneys with grade III to IV hydronephrosis, 24 (32%) showed resolution at a median of 29 months (interquartile range: 24-41 months), and 56 (74%) showed improvement to grade II or less at a median of 12 months (interquartile range: 5-23 months). Of the 76 kidneys with grade III to IV hydronephrosis, five required delayed pyeloplasty at a median of 66 months (interquartile range: 42-89 months). One patient was asymptomatic, with a marked worsening of hydronephrosis and decreased renal function 6 years after the resolution of hydronephrosis. CONCLUSIONS: None of the patients with grade I to II hydronephrosis required surgical treatment, and a shorter follow-up may be sufficient. Grade III to IV severe hydronephrosis should be considered for a longer and more careful follow-up, given the possibility of asymptomatic exacerbation of hydronephrosis.

Clinical impact of the intensity of follow-up cystoscopy in patients with high-risk non-muscle-invasive bladder cancer.

PURPOSE: There is significant lack on evidence regarding the effect of non-adherence to a recommended protocol in follow-up of high-risk non-muscle-invasive bladder cancer (NMIBC), or the impact of delaying detection of recurrent lesion. Here, we aimed to investigate the optimal frequency of follow-up cystoscopy of high-risk NMIBC with respect to oncological safety in the Japanese real-world clinical practice. METHODS: This retrospective single-center study included 206 patients with primary high-risk NMIBC. The intensity (%) of follow-up cystoscopy was calculated based on actual visits for cystoscopy and guideline-recommended frequency in the first 24-month follow-up period. Inverse probability of treatment weighting analyses was used to reduce the risk of bias between groups. We performed a restricted cubic spline analysis with knots at intensity of follow-up cystoscopy ≤ 100% group to examine the possible association of progression risk with the intensity of follow-up as a continuous exposure. RESULTS: The median intensity was 87.5% (interquartile range, 75-100). Adjusted multivariate analysis for MIBC-free and progression-free survival demonstrated no significant difference between adjusted ≤ 75% and > 75% intensity groups. A restricted cubic spline analysis suggested no significant effect of the intensity of follow-up on progression risk, and hazard ratios of patients of < 100% intensity were equivalent to those of patients of 100% intensity. CONCLUSION: Our finding suggested decreased intensity of follow-up cystoscopy did not affect oncological outcomes in patients with high-risk NMIBC. Further prospective trials directly aimed at investigating optimized follow-up schedules for NMIBC are mandatory before substantial changes to existing clinical guidelines.

Assessment of diagnostic accuracy for cryptorchidism and risk factors for delayed orchidopexy.

OBJECTIVES: Cryptorchidism (CO) diagnosis by palpation is challenging. Patients with suspected CO are primarily referred to pediatric urologists by general pediatricians and urologists. Currently, surgical treatment for CO is recommended earlier than in previous guidelines. In this study, we evaluated factors that lead to diagnosis discordance and delayed orchidopexy in patients referred with suspected CO in addition to timing of initial screening. METHODS: In total, 731 patients (1052 testes) with suspected CO were included. Risk factors for diagnostic discrepancy in CO diagnosis by pediatric urologists and risk of delayed orchiopexy were evaluated. RESULTS: Herein, 659 (90%) patients were diagnosed during routine public health checkups for infants and young children, and 419 (57%) patients were referred by pediatric practitioners. Of 1052 testes, 374 (36%) were diagnosed with CO by pediatric urologists. In multivariate analysis, risk factors of diagnostic discrepancy for CO diagnosis by pediatric urologists were bilateral testis (odds ratio [OR] = 9.17, p < 0.0001), >6 months old at initial diagnosis (OR = 1.036, p < 0.0001), and pediatric referral (OR = 4.60, p < 0.0001). In total, 296 patients underwent orchiopexy for CO. In multivariate analysis, risk factors for delayed orchiopexy were presence of comorbidities (OR = 3.43, p = 0.003) and >10 months old at referral (OR = 12.62, p < 0.0001). CONCLUSIONS: Pediatric referral is a risk factor for discordant CO diagnostics, and late age at referral brings a risk of delayed orchiopexy. It is necessary to enlighten pediatricians, who are mainly responsible for routine health checkups, in teaching CO diagnostic techniques to ensure early referral.

Enfortumab vedotin following platinum-based chemotherapy and immune checkpoint inhibitors for advanced urothelial carcinoma: response, survival and safety analysis from a multicentre real-world Japanese cohort.

OBJECTIVE: Real-world evidence regarding enfortumab vedotin for unresectable or metastatic urothelial carcinoma is scarce, particularly in Japan. We investigated real-world data focusing on patient background, previous treatments, response, survival and adverse events in patients receiving enfortumab vedotin. METHODS: A multicentre database was used to register 556 patients diagnosed with metastatic urothelial carcinoma from 2008 to 2023; 34 patients (6.1%) treated with enfortumab vedotin were included. Best radiographic objective responses were evaluated using the Response Evaluation Criteria in Solid Tumors (v1.1) during treatments. Overall survival and progression-free survival were estimated (Kaplan-Meier method). Toxicities were reported according to the Common Terminology Criteria for Adverse Events, version 5.0. The relative dose intensity, which could impact oncological outcomes, was calculated. RESULTS: The median number of enfortumab vedotin therapy cycles was 5. The best objective response to enfortumab vedotin was partial response, stable disease and progressive disease in 19 (56%), 5 (15%) and 10 (29%) patients, respectively. The median overall survival and progression-free survival after the first enfortumab vedotin dose were 16 and 9 months, respectively. No significant relationship was observed between survival outcomes after enfortumab vedotin initiation and the enfortumab vedotin relative dose intensity. The median overall survival from first-line platinum-based chemotherapy initiation was 42 months. Twenty-six (76%) patients experienced any grade of enfortumab vedotin-related toxicities; eight (24%) experienced Grades 3-4 toxicities, the most common being skin toxicity (any grade, 47%; Grades 3-4, 12%). CONCLUSIONS: Here, we report real-world evidence for enfortumab vedotin therapy in Japan. Tumour responses and safety profiles were comparable with those of clinical trials on this novel treatment.

Impact of nutrition and inflammation indicators on peritoneal dialysis initiation and management.

BACKGROUND: The clinical significance of nutrition and inflammation in dialysis patients is well established. This study aimed to evaluate the association between prognosis and indicators of nutrition and inflammation. METHODS: A total of 253 consecutive patients who underwent peritoneal dialysis (PD) as primary renal replacement therapy at our institute between 2006 and 2021 were included. We retrospectively reviewed the patient's medical charts and obtained their clinical information. Nine nutritional and two inflammatory indicators were assessed. Patient outcomes were investigated, and predictive factors were explored. RESULTS: The median age and follow-up period were 65 years and 54 months, respectively. Most nutritional indicators and C-reactive protein (CRP) levels showed a significant correlation with residual renal function. Multivariate analysis revealed that the survival index, nutritional risk index for Japanese hemodialysis patients, and CRP levels were independent indicators of patient survival (P < 0.001, P = 0.034, and P = 0.005, respectively) and cardiovascular disease-free survival (P = 0.009, P = 0.04, and P = 0.017, respectively). Patients with a survival index < 19 and CRP ≥ 0.5 had a high risk of mortality and cardiovascular death (P < 0.0001 and P = 0.0002, respectively). CONCLUSIONS: Our findings suggest that indicators of nutrition and inflammation play important roles in predicting patient outcomes. Further research is warranted to establish optimal management strategies for patients on PD.

Utility of a penile compression device for the quality of life in male patients with urinary incontinence after prostatectomy (the MORE study): a randomized prospective study.

OBJECTIVES: To verify the effects of penile clamping on the degree of stress urinary incontinence and quality of life in post-radical prostatectomy patients. RESULTS: Thirty-seven patients suffering from stress urinary incontinence after undergoing radical prostatectomy were enrolled. A total of 19 and 18 patients were analyzed in the non-clamp and clamp groups, respectively. The mean ages of the patients in non-clamp and clamp groups were 68.3 ± 7.1 years and 71.2 ± 4.8 years, respectively; the mean time after radical prostatectomy was 28.9 ± 44.0 months and 26.2 ± 39.0 months, respectively. The penile clamp used was the CLAMPMED® (URINE CONTROL CLAMP) size M (MURANAKA MEDICAL INSTRUMENTS Co., Ltd.). Specific urinary care pads (Sawayaka Pad for Men, Small Quantity®, Unicharm Corporation), were provided; the average daily usage was monitored for four weeks. The quality of life was evaluated using the King's Health Questionnaire. The average daily use of urinary care pads was significantly reduced in the clamp group than in the non-clamp group (-0.83 ± 1.51 vs. -0.16 ± 0.69, P = 0.0071). King's Health Questionnaire scores did not change significantly in either group. Wearing the CLAMPMED® reduced the amount of urinary incontinence but did not improve the quality of life. TRIAL REGISTRATION: The Japan Registry of Clinical Trials (jRCT1052230083). Registered 2 August, 2023.

Quality of life after non-nerve-sparing, robot-assisted radical prostatectomy.

OBJECTIVE: To evaluate quality of life (QOL) after non-nerve-sparing, robot-assisted radical prostatectomy (RARP) and factors associated with worsened QOL. METHODS: Patients who underwent non-nerve-sparing RARP (n = 115) were enrolled. The Expanded Prostate Cancer Index Composite and 8-item Short Form Health Survey were used to evaluate QOL at baseline and postoperative 1, 3, 6, 12, and 24 months. Preoperative factors were evaluated by multivariate analysis for worsened QOL. RESULTS: Postoperative 24-month urinary QOL worsened in 68 of 115 (59%) patients. In multivariate analysis, membranous urethral length ≥10.8 mm [odds ratio (OR): .26, 95% confidence interval (CI): .07-.96] and intravesical prostatic protrusion ≥12 mm (OR: .14, 95% CI .06-.35) were significantly associated with maintaining postoperative 24-month urinary QOL. Significantly more patients with intravesical prostatic protrusion ≥12 mm than < 12 mm had improved urinary QOL. At postoperative 24 months, 43 of 115 (38%) patients had worsened sexual QOL. In multivariate analysis, higher Sexual Health Inventory for Men score (OR: 8.39, 95% CI 2.28-30.9), sexual activity (OR: 6.94, 95% CI: 2.27-21.2), and intercourse activity (OR: 6.81, 95% CI: 1.64-28.3) preoperatively were significantly associated with worsened postoperative 24-month sexual QOL. More patients with high preoperative intercourse activity (12/23,53%) had significantly worsened (p = .009) QOL regarding sexual bother than those who had no preoperative intercourse activity (21/92, 23%). CONCLUSION: After non-nerve-sparing RARP, patients with long membranous urethral length and/or intravesical prostatic protrusion maintain urinary QOL. Patients with high intercourse activity presented with impairment of sexual QOL after non-nerve-sparing RARP.

Chronological Changes in Emotional Status and Vaccine Implementation Rate Among Patients on the Waiting List for Deceased-Donor Kidney Transplantation During the Prolonged COVID-19 Pandemic.

BACKGROUND: To investigate the emotional attributes and vaccine implementation rate of patients waiting for kidney transplants during the prolonged COVID-19 pandemic. METHODS: We included 145 patients who were on the waiting list at our institution. Clinical information was obtained from medical charts, and emotional changes were assessed using a telephone questionnaire comprising 13 questions, including vaccine implementation. We also investigated factors affecting the decision to accept or decline deceased-donor kidney transplantation during the COVID-19 pandemic. RESULTS: Of the 145 patients, 121 (83.4%) provided informed consent and completed the questionnaire. The median age at registration on the waiting list for deceased-donor kidney transplantation and the median waiting period was 45.5 years and 103 months, respectively. This cohort comprised 84 males and 37 females. Twenty patients (16.5%) were diagnosed with COVID-19, and 15 (12.4%) were more curious about deceased-donor kidney transplantation. One hundred patients (82.6%) were vaccinated against COVID-19 more than thrice. Thirty patients (24.8%) declined, and 91 patients (75.2%) accepted an organ transplant offer during the COVID-19 pandemic. Multivariate analysis revealed that the long-term waiting period (P = .038) and anxiety about COVID-19, such as visiting the transplant facility (P < .0001) and prudence over time (P < .0001), were independent factors influencing the decline of a kidney transplant offer. CONCLUSIONS: Our findings suggest that some patients hesitated to undergo deceased-donor kidney transplantation during the pandemic. There is a need to develop an appropriate system to ensure safe and secure kidney transplantation during prolonged pandemics.

Serum anandamide and lipids associated with linoleic acid can distinguish interstitial cystitis/bladder pain syndrome from overactive bladder: An exploratory study.

OBJECTIVES: Diagnosing interstitial cystitis/bladder pain syndrome presents a major challenge because it relies on subjective symptoms and empirical cystoscopic findings. A practical biomarker should discriminate diseases that cause increased urinary frequency, particularly overactive bladder. Therefore, we aimed to identify blood biomarkers that can discriminate between interstitial cystitis/bladder pain syndrome and overactive bladder. METHODS: We enrolled patients with Hunner-type interstitial cystitis (n = 20), bladder pain syndrome (n = 20), and overactive bladder (n = 20) and without lower urinary tract symptoms (controls, n = 15) at Ueda Clinic and Nara Medical University Hospital from February 2020 to August 2021. The degree of interstitial cystitis/bladder pain syndrome symptoms was evaluated using the interstitial cystitis symptom and problem indices. Metabolomics analysis was performed on 323 serum metabolites using liquid chromatography time-of-flight mass spectrometry. RESULTS: In the Hunner-type interstitial cystitis or bladder pain syndrome group, we observed smaller relative areas, including anandamide, acylcarnitine (18:2), linoleoyl ethanolamide, and arachidonic acid, compared to those in the overactive bladder or control group. Notably, the differences in the relative areas of anandamide were statistically significant (median: 3.950e-005 and 4.150e-005 vs. 8.300e-005 and 9.800e-005), with an area under the curve of 0.9321, demonstrating its ability to discriminate interstitial cystitis/bladder pain syndrome. CONCLUSIONS: Serum anandamide may be a feasible diagnostic biomarker for interstitial cystitis/bladder pain syndrome. Reduced serum anandamide levels may be associated with pain and inflammation initiation, reflecting the pathology of interstitial cystitis/bladder pain syndrome. Furthermore, our findings suggest that abnormal linoleic acid metabolism may be involved in the pathogenesis of interstitial cystitis/bladder pain syndrome.

Impaired nitric oxide mechanisms underlying lower urinary tract dysfunction in aging rats.

The study aimed to investigate the bladder and urethral activity and nitric oxide (NO)-related molecular changes in aging rats. Rats were divided into two groups: Group Y (young rats; 12 wk) and Group A (aging rats; 15 mo). A 24-h voiding assay was performed, and the urodynamic parameters were evaluated using awake cystometry (CMG) and urethral perfusion pressure (UPP) recordings under urethane anesthesia. The mRNA expression levels of NO-, ischemia-, and inflammation-related markers in urethra and bladder tissues and cGMP levels in the urethra were assessed. Body weight was significantly higher in Group A than in Group Y. Voiding assay results (24 h) were insignificant. In the CMG, the number of non-voiding contractions per voiding cycle and post-void residual volume were significantly higher in Group A than in Group Y; voiding efficiency was significantly lower in Group A than in Group Y. In the UPP recordings, the urethral pressure reduction and high-frequency oscillation (HFO) amplitude were significantly lower in Group A than in Group Y. The mRNA expression levels of Hif-1α, Vegf-a, and Tgf-ß1 in the bladder were significantly higher in Group A than in Group Y. The mRNA expression levels of Nos1 and Prkg1 and the cGMP concentrations in the urethra were significantly lower in Group A than in Group Y. Aging rats can be useful models for studying the natural progression of age-related lower urinary tract dysfunctions, for which impaired NO-mediated transmitter function is likely to be an important mechanism.NEW & NOTEWORTHY Aging rats can be useful models for studying the natural progression of age-related lower urinary tract dysfunctions, for which impaired nitric oxide-mediated transmitter function is likely to be an important mechanism.

Clinical impact of catheter insertion for peritoneal dialysis on patient survival and catheter-related complications.

OBJECTIVES: The stepwise initiation of peritoneal dialysis (PD) using Moncrief and Popovich's technique (SMAP) for catheter insertion is recommended for the systemic introduction of PD and prevention of catheter-related infections. In this study, we investigated patient outcomes in patients who underwent insertion of a PD catheter with a direct method versus the SMAP method. METHODS: We enrolled 295 consecutive patients who underwent PD as a primary renal replacement therapy and underwent insertion of a PD catheter at our institute between 2006 and 2021. We retrospectively reviewed their data and investigated patient outcomes, including mortality and PD catheter-related complications. RESULTS: Median age at PD induction was 65 years in the direct insertion group and 65 years in the SMAP group (P = 0.80). The rate of PD introduction after emergency hemodialysis was significantly higher in the direct insertion group than in the SMAP group (P < 0.001). There was no significant difference in survival between the direct insertion and SMAP groups during the median follow-up period of 54 months (P = 0.12). Additionally, patients who transitioned to hemodialysis or kidney transplantation after PD showed significantly longer survival (P < 0.001). The incidence of PD catheter-related complications was not significantly different between the two groups. A body mass index ≥ 23 kg/m2 was an independent risk factor for peritonitis and exit-site infection (P = 0.006 and P = 0.011, respectively). CONCLUSIONS: Planned sequential renal replacement therapy including hybrid hemodialysis, complete hemodialysis, and kidney transplantation after PD is important for improving patient outcomes. PD catheter insertion by SMAP may not be mandatory in our clinical practice.

Diagnostic and Prognostic Roles of Urine Nectin-2 and Nectin-4 in Human Bladder Cancer.

The clinical utility of urine nectins in bladder cancer (BCa) is unclear. We investigated the potential diagnostic and prognostic values of urine Nectin-2 and Nectin-4. Levels of urine Nectin-2, Nectin-4, and NMP-22 were quantified using an enzyme-linked immunosorbent assay in 122 patients with BCa, consisting of 78 with non-muscle-invasive BCa (NMIBC) and 44 with muscle-invasive BCa (MIBC), and ten healthy controls. Tumor nectin expression in MIBC was evaluated with immunohistochemical staining of transurethral resection specimens. The level of urine Nectin-4 (mean: 18.3 ng/mL) was much higher than that of urine Nectin-2 (mean: 0.40 ng/mL). The sensitivities of Nectin-2, Nectin-4, NMP-22, and cytology assays were 84%, 98%, 52%, and 47%, respectively; their specificities were 40%, 80%, 100%, and 100%, respectively. Both urine Nectin-2 and Nectin-4, though not NMP-22, were found to be significantly more sensitive than cytology. A four-titer grouping based on levels of urine Nectin-2/Nectin-4 (low/high, high/high, low/low, and high/low) showed a high capability for discriminating between NMIBC and MIBC. Neither urine Nectin-2 nor Nectin-4 levels had a significant prognostic value in NMIBC or MIBC. Urine levels correlated with tumor expression and serum levels in the Nectin-4 analysis, but not in the Nectin-2 analysis. Urine nectins are potential diagnostic biomarkers for BCa.

Clinical practice of UroVysion® urine test in patients with bladder carcinoma in situ treated with intravesical Bacillus Calmette-Guerin.

In January 2019, the use of the UroVysion® urine test for surveillance of non-muscle invasive bladder cancer with carcinoma in situ (CIS) was approved in Japan. Clinical evidence of its use remains limited. Herein, we report the real-world clinical practice of the UroVysion test. Of 29 patients underwent at least one UroVysion test at our hospital from 2019 to 2022, only two (6.9%) tested positive without any visible tumor on the cystoscopy after the initial transurethral resection: a 77-year-old man with T1 high-grade tumor and concomitant CIS and a 76-year-old woman with CIS. The remaining 27 patients (93.1%) tested negative post-transurethral resection. This study was the first to report the Japanese real-world practice of the UroVysion test, demonstrating relatively low positive rate as compared to the previous reports from other countries. Further clinical evidence from other Japanese institutes needs to be accumulated to update the true value of this test.

Impact of Nocturnal Polyuria and Sleep Quality in Kidney Transplant Recipients With Nocturia.

BACKGROUND: To investigate the quality of life (QOL) of patients with nocturia after kidney transplantation (KT) and the association between nocturnal polyuria and sleep quality. METHODS: In a cross-sectional study, a patient who consented was evaluated using the following items: international prostate symptom QOL score, nocturia-quality of life score, overactive bladder symptom score, Pittsburgh sleep quality index, bladder diary, uroflowmetry, and bioimpedance analysis. Clinical and laboratory data were obtained from medical charts. RESULTS: Forty-three patients were included in the analysis. Approximately 25% of patients urinated once at night, and 58.1% had nocturia twice. Nocturnal polyuria was observed in 86.0% of patients, and overactive bladder was observed in 23.3% of patients. According to the Pittsburgh sleep quality Index, 34.9% of patients had poor sleep quality. Multivariate analysis revealed that patients with nocturnal polyuria tended to have a high estimated glomerular filtration rate (P = .058). On the other hand, multivariate analysis for poor sleep quality revealed that high body fat percentage and low nocturia-quality of life total score were independently correlated factors (P = .008 and P = .012, respectively). Furthermore, the patients with nocturia ≥3/night were significantly older than those with nocturia ≤2/night (P = .022). CONCLUSION: Nocturnal polyuria, poor sleep quality, and aging may decrease the QOL of patients with nocturia after KT. Further investigations, including optimal water intake and interventions, can lead to better management after KT.
