Comparison of Post-Radical Cystectomy Renal Function and Ileal Conduit-Related Complications Between Extracorporeal and Robot-Assisted Intracorporeal Urinary Diversion: A Single-Center Experience.

Introduction: Limited evidence exists regarding differences in post-operative renal function and ileal conduit-related complications, including ureteroenteric anastomotic stricture (UAS) and parastomal hernia (PH), between radical cystectomy (RC) with extracorporeal urinary diversion (ECUD) and robot-assisted RC with intracorporeal UD (ICUD).

Methods: We retrospectively collected the baseline and post-RC follow-up data from 179 patients receiving RC with ileal conduit UD (152 ECUD and 27 ICUD). The estimated glomerular filtration rate (eGFR, mL/min/1.

[A Case of Mycoplasma genitalium Urethritis Refractory to Treatment].

A 28-year-old man was diagnosed with chlamydial urethritis by his previous doctor and was prescribed minocycline (MINO). The result of a urinary chlamydia polymerase chain reaction (PCR) test later confirmed to be negative. However, the patient visited our hospital because of persistent miction pain.

Molecular mechanism of formation and destruction of a pseudo‑capsule in clear cell renal cell carcinoma.

The process and molecular mechanisms underlying the formation and destruction of a pseudo-capsule (PC) in clear cell renal cell carcinoma (ccRCC) are poorly understood. In the present study, the PCs of surgical specimens from primary tumors and metastatic lesions in 169 patients with ccRCC, and carcinogen-induced ccRCC rat models were semi-quantified using the invasion of PC (i-Cap) score system. This was based on the relationship among the tumor, PC and adjacent normal tissue (NT) as follows: i-Cap 0, tumor has no PC and does not invade NT; i-Cap 1, tumor has a complete PC and does not invade into the PC; i-Cap 2, tumor with focal absences in the PC, which partially invades the PC but not completely through the PC; i-Cap 3, tumor crosses the PC and invades the NT; i-Cap 4, tumor directly invades the NT without a PC.

Treatment patterns and prognosis in patients with Bacillus Calmette-Guérin-exposed high-risk non-muscle invasive bladder cancer: a real-world data analysis.

Purpose: The International Bladder Cancer Group designated the subgroup that is resistant to Bacillus Calmette-Guérin (BCG) but does not meet the criteria for BCG-unresponsive NMIBC as "BCG-exposed high-risk NMIBC" to guide optimal trial design. We aimed to investigate the treatment patterns and prognoses of patients with BCG-exposed NMIBC.

Methods: We conducted a retrospective chart review of 3283 patients who received intravesical BCG therapy for NMIBC at 14 participating institutions between January 2000 and December 2019.

[Efficacy of Recombinant Thrombomodulin for Sepsis-Associated Disseminated Intravascular Coagulation Caused by Urinary Tract Infections].

Severe urinary tract infections occasionally cause sepsis and disseminated intravascular coagulation (DIC). We examined the efficacy of recombinant thrombomodulin (rTM) for treating DIC caused by urosepsis. We enrolled 40 patients who were diagnosed with DIC caused by urosepsis at our hospital between April 2018 and May 2022.

[Adrenal Hemangiomatous Endothelial Cyst That was Difficult to Differentiate from Adrenal Malignant Tumor: A Case Report].

A 65-year-old woman was referred to our hospital for fever and diagnosed with pyelonephritis. Abdominal computed tomography showed a right adrenal tumor incidentally, that was 6.5 cm in diameter.

Composite pheochromocytoma associated with neurofibromatosis type 1.

Introduction: Composite pheochromocytoma is a rare tumor, occurring in only 3% of pheochromocytomas. We report a case of composite pheochromocytoma with neurofibromatosis type 1.

Case Presentation: A 42-year-old man was referred to our department for further evaluation of an incidentally detected right adrenal tumor.

Subsequent Upper Urinary Tract Carcinoma Related to Worse Survival in Patients Treated with BCG.

Upper urinary tract urothelial carcinoma (UTUC) after intravesical bacillus Calmette-Guerin (BCG) therapy is rare, and its incidence, clinical impact, and risk factors are not fully understood. To elucidate the clinical implications of UTUC after intravesical BCG therapy, this retrospective cohort study used data collected between January 2000 and December 2019. A total of 3226 patients diagnosed with non-muscle-invasive bladder cancer (NMIBC) and treated with intravesical BCG therapy were enrolled (JUOG-UC 1901).

C-reactive protein as a prognostic predictor for non-muscle invasive bladder cancer after intravesical bacillus Calmette-Guérin therapy: A Japan Urological Oncology Group study analysis.

Objective: To investigate the involvement of pretreatment C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR) in the prognosis of patients who underwent intravesical bacillus Calmette-Guérin (BCG) therapy for non-muscle invasive bladder cancer (NMIBC).

Methods: The clinicopathological data of 1709 patients with NMIBC who underwent initial intravesical BCG therapy after transurethral resection of bladder tumor were retrospectively analyzed to evaluate the outcome of intravesical BCG therapy in a multicenter study conducted by the Japan Urological Oncology Group. The prognoses of these patients were analyzed to determine whether the biomarkers (CRP and NLR) could predict the efficacy of intravesical BCG therapy.

Probiotics enhances anti-tumor immune response induced by gemcitabine plus cisplatin chemotherapy for urothelial cancer.

Chemotherapy drugs, such as gemcitabine and cisplatin (GC), are frequently administered to patients with advanced urothelial carcinoma, however the influence of the gut microbiota on their action is unclear. Thus, we investigated the effects of GC on the gut microbiome and determined whether oral supplementation with a probiotics mixture of Lactobacillus casei Shirota and Bifidobacterium breve enhanced the anti-tumor immune response. After subcutaneous inoculation with MBT2 murine bladder cancer cells, syngenic C3H mice were randomly allocated into eight groups.

5‑Aminolevurinic acid inhibits the proliferation of bladder cancer cells by activating heme synthesis.

Iron is an essential nutrient that facilitates cell proliferation and growth, and it can contribute to tumor growth. Although iron chelators have shown great potential in preclinical cancer models, they can cause adverse side‑effects. The aim of the present study was to determine whether treatment with 5‑aminolevurinic acid (5‑ALA) has antitumor effects in bladder cancer, by reduction of mitochondrial iron without using an iron chelator, through activation of heme synthesis.

Real-world treatment patterns and oncological outcomes in early relapse and refractory disease after bacillus Calmette-Guérin failure in non-muscle-invasive bladder cancer.

Objective: To assess real-world oncological outcomes between the radical cystectomy (RC) group and non-RC group for early relapse and refractory disease.

Methods: We retrospectively analyzed 953 patients with recurrent non-muscle-invasive bladder cancer (NMIBC) who received bacillus Calmette-Guérin (BCG) at 31 affiliated hospitals from 2000 to 2019. Patients with missing data on the timing of failure were excluded and 871 patients remained eligible, of whom 447, 357, and 67 were classified as early relapse/refractory disease, intermediate/late relapse disease, and intolerant disease, respectively.

Site-specific Risk Stratification Models for Postoperative Recurrence and Survival Prediction in Patients with Upper Tract Urothelial Carcinoma Undergoing Radical Nephroureterectomy: Better Stratification for Adjuvant Therapy.

Background: Site-specific postoperative risk models for localized upper tract urothelial carcinoma (UTUC) are unavailable.

Objective: To create specific risk models for renal pelvic urothelial carcinoma (RPUC) and ureteral urothelial carcinoma (UUC), and to compare the predictive accuracy with the overall UTUC risk model.

Design Setting And Participants: A multi-institutional database retrospective study of 1917 UTUC patients who underwent radical nephroureterectomy (RNU) between 2000 and 2018 was conducted.

Association of Increased Age With Decreased Response to Intravesical Instillation of Bacille Calmette-Guérin in Patients With High-Risk Non-Muscle Invasive Bladder Cancer: Retrospective Multi-Institute Results From the Japanese Urological Oncology Research Group JUOG-UC-1901-BCG.

Objective: To compare the therapeutic effect of Bacille Calmette-Guérin (BCG) intravesical instillation in older and younger patients with high-risk non-muscle-invasive bladder cancer. The comparison was performed with propensity score matching (PSM) without terminating the death of the older patients using relatively large-scale retrospective data from multiple institutes in Japan.

Materials And Methods: Overall, 3283 patients diagnosed with non-muscle-invasive bladder cancer treated with intravesical BCG instillation during 2000-2018 in 31 institutes were examined; 1437 and 602 patients with high-grade T1 and Tis tumors were divided into those aged ≥75 and <75 years.

Impact of carcinoma in situ on the outcome of intravesical Bacillus Calmette-Guérin therapy for non-muscle-invasive bladder cancer: a comparative analysis of large real-world data.

Background: This study investigated the clinical impact of carcinoma in situ (CIS) in intravesical Bacillus Calmette-Guérin (BCG) therapy for patients with non-muscle-invasive bladder cancer (NMIBC).

Methods: This study retrospectively evaluated 3035 patients who were diagnosed with NMIBC and treated by intravesical BCG therapy between 2000 and 2019 at 31 institutions. Patients were divided into six groups according to the presence of CIS as follows: low-grade Ta without concomitant CIS, high-grade Ta without concomitant CIS, high-grade Ta with concomitant CIS, high-grade T1 without concomitant CIS, high-grade T1 with concomitant CIS, and pure CIS (without any papillary lesion).

Prognostication in Japanese patients with bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer undergoing early radical cystectomy.

Objectives: The US Food and Drug Administration recently defined the clinical term "bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer" as a disease state resistant to adequate bacillus Calmette-Guérin therapy. There is a significant lack of prognostication for this disease even in patients who have undergone early radical cystectomy. This study aimed to identify the clinical outcomes and prognostic factors in Japanese patients with bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer who underwent early radical cystectomy.

Bacillus Calmette-Guérin-unresponsive non-muscle invasive bladder cancer outcomes in patients without radical cystectomy.

Background: Bacillus Calmette-Guérin (BCG)-unresponsive non-muscle invasive bladder cancer (NMIBC) is a newly defined subtype that is unlikely to benefit from BCG rechallenge. Radical cystectomy is currently recommended for BCG-unresponsive NMIBC; however, a certain proportion of these patients can be managed with treatments other than that. Herein, we conducted a multicenter retrospective study to analyze the clinical outcomes of BCG-unresponsive NMIBC patients who did not receive radical cystectomy.

Intravesical Bacillus Calmette-Guérin Treatment for T1 High-Grade Non-Muscle Invasive Bladder Cancer with Divergent Differentiation or Variant Morphologies.

The 2016 World Health Organization classification newly described infiltrating urothelial carcinoma (UC) with divergent differentiation (DD) or variant morphologies (VMs). Data comparing oncological outcomes after bladder-preservation therapy using intravesical Bacillus Calmette-Guérin (BCG) treatment among T1 bladder pure UC (pUC), UC with DD (UC-DD), and UC with VMs (UC-VM) are limited. We evaluated 1490 patients with T1 high-grade bladder UC who received intravesical BCG during 2000-2019.

Impact of Radical Nephrectomy and Partial Nephrectomy on Actual Estimated Overall Survival Compared to Life Expectancy in Patients with Renal Cell Carcinoma.

Purpose: Reports suggest that partial nephrectomy provides no significant benefit in terms of cancer-specific and overall survival (OS) compared to radical nephrectomy. Here, we focused on survival in terms of life expectancy and investigated the significance of partial nephrectomy for localized renal cell carcinoma (RCC) patients.

Patients And Methods: Our retrospective study included 937 patients (median age 63 years) with localized RCC who underwent partial nephrectomy or radical nephrectomy.

Clinical outcomes after intravesical bacillus Calmette-Guérin for the highest-risk non-muscle-invasive bladder cancer newly defined in the Japanese Urological Association Guidelines 2019.

Objective: To assess the clinical outcomes of highest-risk non-muscle-invasive bladder cancer patients treated with intravesical bacillus Calmette-Guérin.

Methods: The medical charts of patients with non-muscle-invasive bladder cancer treated with intravesical bacillus Calmette-Guérin between 2000 and 2018 at a single institution were retrospectively reviewed. Patients were stratified into three groups (intermediate-, high- and highest-risk groups) according to the risk classification of the updated Japanese Urological Association guidelines 2019.

Non-maintenance intravesical Bacillus Calmette-Guérin induction therapy with eight doses in patients with high- or highest-risk non-muscle invasive bladder cancer: a retrospective non-randomized comparative study.

Background: To explore possible solutions to overcome chronic Bacillus Calmette-Guérin (BCG) shortage affecting seriously the management of non-muscle invasive bladder cancer (NMIBC) in Europe and throughout the world, we investigated whether non-maintenance eight-dose induction BCG (iBCG) was comparable to six-dose iBCG plus maintenance BCG (mBCG).

Methods: This observational study evaluated 2669 patients with high- or highest-risk NMIBC who treated with iBCG with or without mBCG during 2000-2019. The patients were classified into five groups according to treatment pattern: 874 (33%) received non-maintenance six-dose iBCG (Group A), 405 (15%) received six-dose iBCG plus mBCG (Group B), 1189 (44%) received non-maintenance seven-/eight-dose iBCG (Group C), 60 (2.

Inhibitory Effect of Orally Administered 5-Aminolevulinic Acid on Prostate Carcinogenesis in the FVB-Transgenic Adenocarcinoma of a Mouse Prostate (FVB-TRAMP) Model.

Background: 5-aminolevulinic acid (5-ALA) is a constituent of mitochondrial electron carriers, heme and cytochrome c, which are crucial for aerobic energy metabolism and cell apoptosis. We investigated the chemopreventive efficacy of 5-ALA against prostate cancer using the FVB-transgenic adenocarcinoma of mouse prostate (FVB-TRAMP) model.

Methods: Samples were collected from 24 FVB-TRAMP mice at 12 and 20 weeks of age (named the first and second sets, respectively).
