We report three cases of a primary malignant lymphoma of the urinary bladder. The radiological features revealed a sessile mass of the lateral wall for one case, a circumferential thickening in the second, and two separated masses of the bladder wall in the last case. Primary malignant lymphoma of the urinary bladder is extremely rare. From a review of the literature, the clinical and radiological findings are discussed. In this paper we report the first case of urinary bladder lymphoma presented on CTas multiple masses.

Bowel regimens before radical cystectomy: An analysis of a modern cohort.

Int J Urol

January 2025

Department of Urology, Sidney Kimmel Medical College, Thomas Jefferson University, Philadelphia, Pennsylvania, USA.

Introduction: Bowel regimens (BR) before radical cystectomy (RC) are currently not recommended by Enhanced Recovery After Surgery (ERAS) protocols, as prior studies have shown BRs lead to worsened outcomes. However, many of those studies have used historic literature before recent surgical advancements such as minimally invasive RC and have not investigated the impact BRs have by type of urinary diversion. Our goal is to determine the outcomes of preoperative BR in patients undergoing RC based on diversion type using a modern patient cohort.

Primary bladder neck obstruction in females: Case series from the Indonesian population.

Int J Surg Case Rep

December 2024

Department of Urology, Faculty of Medicine, Airlangga University, Dr. Soetomo General Academic Hospital, Surabaya, Indonesia.

Introduction: Primary bladder neck obstruction (PBNO) is a rare but significant cause of BOO and LUTS in females, with unclear etiology involving theories of fibrotic narrowing, tissue hyperplasia, or muscle abnormalities. Due to nonspecific symptoms, PBNO diagnosis remains challenging, and optimal surgical treatment needs to be better defined.

Case Presentation: We report two cases of females in their 50s with recurrent urinary retention managed by indwelling catheters.

PD-L1 expression in high-risk non-muscle invasive bladder cancer is not a biomarker of response to BCG.

World J Urol

January 2025

Department of Urology, Erasmus University Medical Center, Erasmus MC Cancer Institute, Dr. Molewaterplein 40, Room Be-304, 3015 GD, Rotterdam, The Netherlands.

Purpose: Up to 50% of high-risk non-muscle invasive bladder cancer (HR-NMIBC) patients fail Bacillus Calmette-Guérin (BCG) treatment, resulting in a high risk of progression and poor clinical outcomes. Biomarkers that predict outcomes after BCG are lacking. The antitumor effects of BCG are driven by a cytotoxic T cell response, which may be controlled by immune checkpoint proteins like Programmed Death Ligand 1 (PD-L1).

Limited research into the tumor immune microenvironment (TIME) for bladder urothelial carcinoma (BUC), particularly the neglect of the intratumoral microbiota, has hindered the development of immunotherapies targeting BUC. Here, we collect 401 patients with BUC with host transcriptome samples and matched tumor microbiome samples from The Cancer Genome Atlas database. Besides, two independent BUC cohorts receiving immunotherapy were obtained.
