A case of mucosal-associated lymphoid tissue lymphoma of the urachus.

Introduction: Urachus carcinoma is a rare malignancy with an aggressive potential and a poor prognosis, and evidence is limited for its diagnosis and treatment.

Case Presentation: A 75-year-old man underwent fluorodeoxyglucose positron emission tomography/computed tomography for staging prostate cancer, and a mass (standardized uptake value max 9.5) was observed on the outside of the urinary bladder dome.

A case of tape infection 19 years after insertion of a tension-free vaginal tape sling.

Introduction: Tape infection after insertion of tension-free vaginal tape is a well-known but rare complication. We report a patient who experienced a subcutaneous abscess 19 years after the surgery.

Case Presentation: A 41-year-old woman presented with fever and lower abdominal pain.

Impact of preoperative systemic immune-inflammation Index on oncologic outcomes in bladder cancer patients treated with radical cystectomy.

Purpose: To investigate the predictive and prognostic value of the preoperative systemic immune-inflammation index (SII) in patients undergoing radical cystectomy (RC) for clinically non-metastatic urothelial cancer of the bladder (UCB).

Methods: Overall, 4,335 patients were included, and the cohort was stratified in two groups according to SII using an optimal cut-off determined by the Youden index. Uni- and multivariable logistic and Cox regression analyses were performed, and the discriminatory ability by adding SII to a reference model based on available clinicopathologic variables was assessed by area under receiver operating characteristics curves (AUC) and concordance-indices.

Impact of the preoperative modified Glasgow Prognostic Score on disease outcome after radical cystectomy for urothelial carcinoma of the bladder.

Background: To investigate the predictive and prognostic value of the preoperative modified Glasgow Prognostic Score (mGPS) in patients with urothelial carcinoma of the bladder (UCB) treated with radical cystectomy (RC).

Methods: We conducted a retrospective analysis of an established multicenter database consisting of 4335 patients who were treated with RC±adjuvant chemotherapy for UCB between 1979 and 2012. The mGPS of each patient was calculated on the basis of preoperative serum C-reactive protein and albumin.

An adrenal incidentaloma caused by synchronous and isolated metastasis.

We report a patient with adrenal incidentaloma due to synchronous and isolated metastasis from lung cancer, which is a relatively rare condition. Close checkups for incidentaloma in oncologic patients are mandatory, leading to successful operation.

Inflammatory myofibroblastic bladder tumor with divergent behavior in a patient with spinal cord injury.

Introduction: An inflammatory myofibroblastic tumor of the bladder is rare. Some urothelial carcinoma with sarcomatoid changes may mimic an inflammatory myofibroblastic tumor.

Case Presentation: A 76-year-old man with indwelling urinary catheters because of a spinal cord injury presented with gross hematuria.

Biofilm formation among methicillin-resistant Staphylococcus aureus isolates from patients with urinary tract infection.

Staphylococci have been confirmed to form biofilms on various biomaterials. The purpose of this study was to investigate biofilm formation among methicillin-resistant Staphylococcus aureus (MRSA) isolates from patients with urinary tract infection (UTI) and to assess the relationship between biofilm-forming capacities and virulence determinants/clinical background. Over a 12-year period from 1990 through 2001, a total of 109 MRSA isolates were collected from patients (one isolate per patient) with UTI at the urology ward of Okayama University Hospital.
