Primary bladder mucinous adenocarcinoma is a rare genitourinary cancer. Here, we present the case of a 75-year-old woman where pathological and imaging findings led to the diagnosis of primary bladder mucinous adenocarcinoma. She underwent treatment with paclitaxel-ifosfamide-cisplatin (TIP).

Investigation of risk factors for vaginal dehiscence and development of small bowel evisceration after robot-assisted radical cystectomy for female bladder cancer and an improved vaginal reconstruction technique to prevent its onset.

Transvaginal organ prolapse, such as small bowel evisceration, is a rare complication after radical cystectomy (RC) in female patients with invasive bladder cancer, However, it often requires emergency surgical repair. Here, we describe our experience with such a case and a review of similar previously reported cases, along with evaluation of the risk factors. We also propose a vaginal reconstruction technique to prevent this complication during robot-assisted laparoscopic radical cystectomy (RARC).

Intraoperative Blood Flow Evaluation Using Indocyanine Green Fluorescence Angiography for the Surgical Reconstruction of a Hilar Renal Artery Aneurysm.

Surgical reconstruction is one of the standard treatments for renal artery aneurysm. However, its intraoperative evaluation is sometimes difficult depending on the operative field, aneurysm morphology, and peripheral blood vessel distribution. This case demonstrated that after renal artery reconstruction, indocyanine green fluorescence angiography is used to evaluate the results of repairing.

Vibegron 50 mg Once Daily Improves OABSS, OAB-q SF Score in OAB Patients ≥80 Years Old in Real-World Clinical Settings and Switching from Other OAB Drugs May Reduce Residual Urine Volume.

Objective: The treatment effects of vibegron have not previously been evaluated in a prospective, non-interventional observational study of elderly Japanese patients, particularly those ≥80 years old. In addition, no reports have referred to residual urine volume in switching cases. We therefore grouped patients by condition and investigated the treatment effects of vibegron on Overactive Bladder Symptom Score (OABSS), Overactive Bladder Questionnaire Short Form (OAB-q SF), and residual urine volume in each group.

Primary adrenal Ewing's sarcoma family of tumors with tumor thrombus of the inferior vena cava: a case report.

Background: Ewing's sarcoma is a malignant neoplasm that mainly occurs in skeletal tissue but can rarely arise in soft tissues. Recently, small round cell tumors (including Ewing's sarcoma) caused by chromosomal translocations have been collectively termed Ewing's sarcoma family of tumors. We report a rare case of primary adrenal Ewing's sarcoma family of tumors with tumor thrombus.

Sarcopenia and the rate of change of the neutrophil/lymphocyte ratio as predictors of pembrolizumab efficacy in advanced urothelial carcinoma.

The objective was to evaluate the usefulness of sarcopenia and the neutrophil/lymphocyte ratio (NLR) as therapeutic efficacy predictors in patients who received pembrolizumab after platinum-based chemotherapy for advanced urothelial carcinoma (aUC). Forty-four patients with aUC were enrolled. Patients' background characteristics and clinical factors, the skeletal muscle index, and the psoas muscle index were evaluated.

Successful treatment with DCF chemotherapy and radiotherapy for primary squamous cell carcinoma of the prostate.

Introduction: Primary squamous cell carcinoma of the prostate is an extremely rare tumor with poor prognosis. Squamous cell carcinoma of the prostate is estimated to comprise less than 1% of all prostate carcinomas. We report herein a case with clinical response to docetaxel, cisplatin, and 5-fluorouracil chemotherapy with radiotherapy, in a patient with metastatic squamous cell carcinoma of the prostate.

Tadalafil 5 mg Once Daily Improved Each IPSS Subscore, QOL, and Nocturia in Elderly BPH Patients over 70 Years Old in a Real-World Clinical Setting.

Objective: No reports have evaluated the treatment effects of tadalafil by age group in a positive, noninterventional observational study of Japanese men. The present study aimed to evaluate the treatment effects of tadalafil by age group in a positive, noninterventional observational study of Japanese men. We therefore divided patients into 2 groups about the age of 70 years and investigated the treatment effects of tadalafil regarding voiding and storage functions by age group.

Evaluation of a rapid one-step PSA test for primary prostate cancer screening.

Background: To enhance the convenience and reduce the cost of prostate cancer (PC) screening, a one-step prostate-specific antigen (PSA) test was evaluated in a large population. The PSA SPOT test kit enables rapid detection of human PSA in serum or plasma at or above a cutoff level of 4 ng/mL to aid in the diagnosis of PC.

Methods: PC screening using the PSA SPOT test was offered to male participants in educational public lectures that we conducted in various cities.

IgG4-related tubulointerstitial nephritis accompanied with cystic formation.

Background: An immunoglobulin G4 (IgG4)-related disease is important disease in differential diagnosis of tumors in kidney, pancreas, lung and other organs. The imaging findings of IgG4-related kidney diseases are usually expressed as defect contrast region, while cystic formation in kidney is extremely rare. Here, we report a case of IgG4-related tubulointerstitial nephritis with renal cystic change caused by the narrowing or obstruction of collecting duct in renal medulla.

[First experiences of laparoscopic radical cystectomy].

Purpose: We determined whether laparoscopic radical cystectomy (LRC) was useful for the patients with bladder cancer.

Materials And Methods: We investigated the surgical outcome of LRC in the initial 30 patients with bladder cancer.

Results: Mean patients age was 68 (54-81) years old.

SNRPE is involved in cell proliferation and progression of high-grade prostate cancer through the regulation of androgen receptor expression.

Clinically high-grade prostate cancers (PC) with high Gleason scores of 8-10 exhibit rapid growth and are more likely to spread beyond the prostate. These cancer types demonstrate a poor response to androgen deprivation therapy and eventually acquire a castration-resistant phenotype. To identify novel molecular cancer drug targets, we previously analyzed the gene expression profiles of high-grade PC using a cDNA microarray combined with laser microbeam microdissection and found a number of genes that are transactivated in high-grade PC.

[The clinical value of 3 tesla diffusion-weighted magnetic resonance imaging in the diagnosis of prostate cancer].

Diffusion-weighted imaging (DWI) is a magnetic resonance imaging (MRI) method and is considered potentially useful for detecting prostate cancer. We evaluated the clinical value of DWI with apparent diffusion coefficient (ADC) maps in addition to T2-weighted imaging (T2WI) using 3 tesla (3 T) MRI. Thirty-three patients with elevated prostate specific antigen were evaluated by MRI with T2WI and DWI prior to transperineal template-guided mapping biopsy.
