Differences in Clinical Outcomes and Survival Among Primary, Secondary, and Concomitant Carcinoma In Situ of the Bladder.

Purpose: Carcinoma in situ (CIS) is a flat, high-grade, and aggressive form of urothelial carcinoma with a high risk of progression to muscle-invasive disease and metastasis. This study aimed to investigate differences in clinical outcomes and survival among patients with primary, secondary, and concomitant CIS of the bladder.

Methods: A total of 209 patients diagnosed with CIS between 2010 and 2022 in our department with a minimum follow-up of 12 months were retrospectively analyzed.

Simple predictors for the completion of scheduled gemcitabine‑cisplatin regimens based on real‑world urothelial cancer data.

Gemcitabine plus cisplatin (GC) is the standard first line of chemotherapy for urothelial carcinoma. However, it is often difficult to complete scheduled GC therapy because of real-world adverse events. Therefore, the reasons behind delays, scheduled cancelations and determined predictive factors for completing scheduled GC therapy were retrospectively analyzed.

IL-6-Producing Pheochromocytoma Associated With Von Hippel Lindau Disease: A Case Report With Literature Review.

We present a first case report of an IL-6-producing pheochromocytoma associated with von Hippel Lindau (vHL) disease. Pheochromocytomas are rare tumors that produce catecholamines, leading to various symptoms. In this case, a 28-year-old woman with a family history of vHL disease presented with a prolonged fever.

Impact of Fish Intake Frequency on Cardiovascular Disease-Specific Survival in Hemodialysis Patients.

Introduction: Cardiovascular disease (CVD) is the leading cause of death in hemodialysis patients (HPs). As a food source, fish contains both CVD-preventive and CVD-promoting fatty acids; however, there is no consensus on fish consumption as a preventive measure for CVD in HPs. This single-center longitudinal cohort study aims to assess the impact of fish intake frequency (FIF) per week on CVD in Japanese HPs.

External iliac arterial dissection after robot-assisted radical cystectomy with an intracorporeal ileal conduit and extended pelvic lymph node dissection.

Introduction: External iliac arterial dissection after robot-assisted laparoscopic procedures is an extremely rare complication. It may cause severe adverse outcomes, such as lower limb necrosis.

Case Presentation: A 73-year-old man was diagnosed with cT2 ≤ N0M0 bladder cancer and underwent robot-assisted radical cystectomy.

A Rare Case of Hernia Incarceration Under the Closed Port-Site Fascia After Robot-Assisted Laparoscopic Radical Cystectomy: Insights and Management Strategies.

Most cases of port-site hernia were due to inadequate fascial closure of the port site. We experienced a rare case of hernia incarceration under the closed port-site fascia despite adequate closure of the fascia after robot-assisted laparoscopic radical cystectomy. In this case, the small intestine was incarcerated between the transversus abdominis and oblique abdominal muscles from the 12-mm trocar site for the assistant.

Laparoscopic ileal ureteral replacement to preserve the natural anti-reflux system: An initial case report.

Introduction: Ileal ureteral replacement is one of the treatment options for long ureteral strictures. Most ileal ureteral replacements anastomose the distal side of the ileal segment directly to the bladder. We have reported here an initial case of laparoscopic ileal ureteral replacement for preserving the natural anti-reflux system.

GATA-3 expression in primary pure choriocarcinoma of the bladder.

Introduction: Primary pure choriocarcinoma of the bladder is extremely rare and should be distinguished from urothelial carcinoma. GATA-3 is a zinc finger transcription factor and a known sensitive immunostaining marker for urothelial carcinoma. However, its accuracy in the detection of urothelial carcinoma is moderate and it is also an important factor in trophoblast differentiation.

Tumor necrosis factor-alpha inhibits differentiation of myogenic cells in human urethral rhabdosphincter.

Objectives: To examine the inhibitory effects of tumor necrosis factor-α on myogenic differentiation of human urethral rhabdosphincter cells.

Methods: A rhabdosphincter sample was obtained from a patient who underwent total cystectomy. To expand the lifespan of the primary cultured cells, rhabdosphincter myogenic cells were immortalized with mutated cyclin-dependent kinase 4, cyclin D1 and telomerase.

Efficacy and Safety of Enoxaparin for Preventing Venous Thromboembolic Events following Urologic Laparoscopic Surgery.

There is a paucity of definitive evidence that supports the use of enoxaparin to prevent venous thromboembolism (VTE) after urologic laparoscopic surgery. The purpose of this study was to evaluate the efficacy and safety of postoperative subcutaneous enoxaparin injection in patients who underwent urologic laparoscopic surgery. A total of 63 patients were evaluated from June 2010 to December 2012.
