Robot-Assisted Surgery and Multigene Panel Testing for Pheochromocytoma and Paraganglioma Syndrome.

Pheochromocytoma and paraganglioma are often associated with hereditary syndromes, particularly those involving genes such as , which is linked to multiple endocrine neoplasia type 2A. Genetic testing plays a crucial role in diagnosing these conditions, guiding treatment strategies, and providing early intervention options for the affected families. A 57-year-old man presenting with back pain was found to have a left adrenal tumor and a retroperitoneal tumor near the left renal hilum.

Impact of Mannitol Administration on Postoperative Renal Function After Robot-Assisted Partial Nephrectomy.

This study investigated the effect of mannitol administration on postoperative renal function during robot-assisted partial nephrectomy (RAPN) in patients with renal cell carcinoma (RCC). Patients with RCC who underwent RAPN at eight Japanese facilities between March 2016 and November 2023 were enrolled. In this study, patients were categorized into two groups according to those who received mannitol during RAPN (Group I) and those who did not receive mannitol (Group II).

The prognostic superiority of second-generation androgen receptor signaling inhibitor in patients with non-metastatic castration-resistant prostate cancer.

Objective: The aim of this study was to compare prognostic outcomes of administering first- or second-generation androgen receptor signaling inhibitors in non-metastatic castration-resistant prostate cancer and to find prognostic indicators.

Methods: This retrospective study included 198 patients with non-metastatic castration-resistant prostate cancer from 14 institutions associated with Tokai Urologic Oncology Research Seminar. Forty-two patients were treated with combined androgen blockade using first-generation inhibitors (bicalutamide or flutamide), and 156 were treated with second-generation inhibitors (abiraterone/enzalutamide or apalutamide/darolutamide) after primary androgen deprivation therapy failure.

Overall Survival and Cancer-Specific Mortality in Patients with Prostate Cancer Undergoing Definitive Therapies: A Narrative Review.

The overall survival (OS) of patients with prostate cancer (PCa) who receive locally definitive therapy is generally better than that of patients who do not receive definitive therapy. There is no difference in the incidence of local recurrence or distant metastasis between treatment modalities. Because the prognosis of PCa is relatively good, many studies have focused on quality of life after treatment as an endpoint.

Combination approach using neoadjuvant therapy with radical prostatectomy for improving oncological outcomes of high-risk prostate cancer: a narrative review.

Background And Objective: Prostate cancer (PCa) is the most common cancer in men. High-risk PCa is associated with an increased risk of PCa-related death. The combined use of androgen deprivation therapy (ADT) is essential to improve oncological outcomes in patients with high-risk PCa, and relatively long-term ADT administration is preferred when radiotherapy is performed.

Metastatic Urothelial Carcinoma With Sarcomatoid Subtype After Robot-Assisted Radical Cystectomy Successfully Treated With Pembrolizumab.

A 76-year-old man who was diagnosed with urothelial carcinoma (UC) in the bladder diverticulum was referred to our institution. The patient was diagnosed with muscle-invasive bladder cancer, which was confirmed by magnetic resonance imaging that showed tumor invasion into the fatty tissue surrounding the diverticulum. After two cycles of neoadjuvant gemcitabine and cisplatin, he underwent robot-assisted radical cystectomy (RARC) with pelvic lymph node dissection followed by intracorporeal ileal conduit.

Effects of low-intensity extracorporeal shock wave on bladder and urethral dysfunction in spinal cord injured rats.

Purpose: To investigate the effects of low-intensity extracorporeal shock wave therapy (LiESWT) on bladder and urethral dysfunction with detrusor overactivity and detrusor sphincter dyssynergia (DSD) resulting from spinal cord injury (SCI).

Methods: At 3 weeks after Th9 spinal cord transection, LiESWT was performed on the bladder and urethra of adult female Sprague Dawley rats with 300 shots of 2 Hz and an energy flux density of 0.12 mJ/mm, repeated four times every 3 days, totaling 1200 shots.

Impact of Cytoreductive Nephrectomy in the Management of Metastatic Renal Cell Carcinoma: A Multicenter Retrospective Study.

In this study, we aimed to determine the utility of cytoreductive nephrectomy (CN) in real-world clinical practice and investigate whether CN contributes to improved oncological outcomes in patients with metastatic renal cell carcinoma (mRCC). This retrospective multicenter cohort study enrolled patients with mRCC who received systemic therapy at six institutions between May 2005 and May 2023. The patients were divided into those who did not undergo CN (Group I) and those who underwent CN (Group II).

A Rare Case of Bladder Metastasis From Endometrial Cancer Treated With Robot-Assisted Radical Cystectomy.

Malignant tumors metastasizing to the bladder are uncommon, and bladder metastasis from uterine cancer is particularly rare. Several cases of bladder metastasis from malignant melanoma, gastric cancer, breast cancer, and renal cancer have been documented. However, to our knowledge, only four cases of bladder metastasis from endometrial cancer had been reported up until 2024.

Discrepancy in the Location of Prostate Cancer Indicated on Biparametric Magnetic Resonance Imaging and Pathologically Diagnosed Using Surgical Specimens.

Accurate diagnosis of the localization of prostate cancer (PCa) on magnetic resonance imaging (MRI) remains a challenge. We aimed to assess discrepancy between the location of PCa pathologically diagnosed using surgical specimens and lesions indicated as possible PCa by the Prostate Imaging Reporting and Data System on MRI. The primary endpoint was the concordance rate between the site of probable clinically significant PCa (csPCa) identified using biparametric MRI (bpMRI) and location of PCa in the surgical specimen obtained using robot-assisted total prostatectomy.

Impact of Robotic-Assisted Partial Nephrectomy with Single Layer versus Double Layer Renorrhaphy on Postoperative Renal Function.

We aimed to investigate the differences in renal function between patients who underwent single inner-layer renorrhaphy (SILR) or double-layer renorrhaphy (DLR) among those with renal tumors who underwent robot-assisted partial nephrectomy (RAPN). This retrospective multicenter cohort study was conducted between November 2018 and October 2023 at two institutions and included patients who underwent RAPN. In total, 93 eligible patients who underwent RAPN were analyzed.

Materials And Methods: This study included 90 patients with histopathologically confirmed bladder cancer (10 SCNECs and 80 UCs). Eight patients with bladder SCNEC and 80 with UC underwent CT and MRI, whereas the remaining two patients with SCNEC underwent CT alone before treatment.

Recombinant antithrombin attenuates acute kidney injury associated with rhabdomyolysis: an in vivo animal study.

Background: Rhabdomyolysis is characterized by the destruction and necrosis of skeletal muscle tissue, resulting in acute kidney injury (AKI). Recombinant antithrombin (rAT) has DNA repair and vascular endothelial-protection properties. Herein, we investigated whether rAT therapy has beneficial effects against rhabdomyolysis-induced AKI.

Glycocalyx analysis of bladder cancer: three-dimensional images in electron microscopy and vicia villosa lectin as a marker for invasiveness in frozen sections.

The abnormal glycocalyx (GCX) on the surface of cancer cells has been reported to be tall and aberrantly glycosylated and has been linked to the progression and spread of cancer-a finding also observed in bladder cancer. However, the characteristics of GCX in various types of human bladder cancer remain unknown, and herein, we aimed to provide information on the diversity of glycan components in the GCX of bladder cancers and to shed light on their characteristics. We used scanning electron microscopy and lanthanum staining to examine the surface GCX of human bladder carcinomas in three-dimensional images, showing the bulky GCX in some carcinomas.
