Cytoreductive nephroureterectomy for treatment of upper urinary tract urothelial carcinoma initially diagnosed as node-positive.

Urothelial carcinomas of the upper urinary tract (UTUC) are rare tumors with a high malignancy degree. Radical nephroureterectomy (RNU) with bladder cuff excision remains one of the standard treatments in clinically localized or locally advanced UTUCs. However, the role of cytoreductive RNU in treating clinically lymph node-positive (N+) UTUCs remains unclear.

Comparative survival outcomes of minimally invasive versus open radical nephroureterectomy for upper tract urothelial carcinoma in Taiwan.

Purpose: Upper tract urothelial carcinoma (UTUC) is rare globally but accounts for 30-40% of urothelial cancers in Taiwan. Radical nephroureterectomy (RNU) with bladder cuff excision (BCE) remains the standard of care for localized or locally advanced disease. Despite the increasing adoption of minimally invasive surgical (MIS) approaches, concerns about their oncological outcomes persist.

Methods: We conducted a retrospective cohort study using data from the Taiwan UTUC Collaboration database. 1590 patients who underwent RNU for UTUC were included in the analysis.

Preoperative ECOG performance status as a predictor of outcomes in upper tract urothelial cancer surgery.

Eastern Cooperative Oncology Group performance status (ECOG-PS) is a widely used functional status measure in oncology, yet its prognostic value in upper tract urothelial carcinoma remains unclear. In this multicenter study of 2473 patients undergoing radical nephroureterectomy, ECOG-PS ≥ 2 was independently associated with worse overall survival (hazard ratio [HR] 2.53, p < 0.

No difference in oncological outcomes and perioperative complications between patients with ESRD with unilateral and bilateral UTUC receiving radical nephroureterectomy.

Patients with end stage renal disease (ESRD) are at high risk of developing upper tract urothelial carcinoma (UTUC). Due to high recurrence rate of UTUC in contralateral kidney and ureter, and high risk of complications related to surgery and anesthesia, whether it's necessary to remove both kineys and ureters at one time remains in debate. We utilized Taiwanese UTUC Registry Database to valuate the difference of oncological outcomes and perioperative complications between patients with ESRD with unilateral and bilateral UTUC receiving surgical resection.

Comparison of the protein acetylome of endothelial cells upon shear flow and resveratrol treatment.

Background: Posttranslational acetylation/deacetylation known as the acetylome is important in regulating protein activity. Shear flow (SF) and resveratrol (RSV) are two stimuli that represent physical and chemical signal separately. The acetylome co-regulated by these two stimuli remain unclear.

The Mechanisms Underlying the Cytotoxic Effects of Copper Via Differentiated Embryonic Chondrocyte Gene 1.

Copper is an essential trace element within cells, but it also exerts cytotoxic effects through induction of reactive oxygen species (ROS) production. To determine the mechanisms underlying copper-induced ROS production, we examined the effects of copper sulfate in HeLa cells. Exposure to copper sulfate led to dose-dependent decreases in HeLa cell viability, along with increases in the subG1 and G2/M populations and corresponding decreases in the G1 population.

The risk factors and complications of forgotten double-J stents: A single-center experience.

Background: Postoperative urology patients may require the insertion of a ureteral stent. However, the delayed removal or change of the ureteral stent may lead to serious consequences for some patients. This study primarily aimed to examine the risk factors and complications associated with forgotten double-J stents (DJSs).

Compare Fuhrman Nuclear and Chromophobe Tumor Grade on Chromophobe RCC.

Background: Chromophobe renal cell carcinoma (chRCC) has a favorable prognosis. Due to irregular nuclei and nuclear pleomorphism, chRCC has a high Fuhrman nuclear grade (FNG). The chromophobe tumor grade (CTG) is a novel three-tier grading system that has been reported to be a better prognosticator than the traditional FNG.

Does the stapler for en bloc resection of renal pedicles during kidney removal surgery increase the risk of arteriovenous fistula?

Background: It was previously thought that renal hilum en bloc ligation during kidney removal may increase the risk of renal arteriovenous fistula (AVF) formation. We evaluated the safety and effectiveness of en bloc ligation of the renal pedicle using a stapler during laparoscopic nephrectomy and nephroureterectomy.

Methods: Ninety patients underwent en bloc renal hilar ligation using 45-mm endo-gastrointestinal anastomosis stapler and 2.
