Purpose: Partial nephrectomy is associated with a 1%-2% risk of renal iatrogenic vascular lesion (IVL) that are commonly treated with selective angioembolization (SAE). The theoretical advantage of SAE is preservation of renal parenchyma by targeting only the bleeding portion of the kidney. Our study aims to assess the long-term effect of SAE on renal function, especially that this intervention requires potentially nephrotoxic contrast load injection.
Materials And Methods: A retrospective review of patients undergoing partial nephrectomy between 2002 and 2018 was performed, and patients who developed IVL were identified. A 1:4 matched case-control analysis was performed. Paired t-test and χ² test were used for continuous and categorical variables, respectively. Multivariable logistic and Cox proportional hazards regression analyses were used to identify risk factors and confounders for SAE and postoperative renal function.
Results: Eighteen patients found to have an IVL after partial nephrectomy were matched with 72 control patients. IVL's were more common in patients after minimally invasive partial nephrectomy (89% vs. 70%, p=0.008) and in those with higher RENAL nephrometry scores (8.8±2.0 vs. 6.5±1.8, p<0.001). On multivariable analysis, lower RENAL scores proved to decrease the odds of requiring postoperative SAE. No significant difference in renal function outcomes was seen at 24 months of follow-up after surgery.
Conclusions: SAE for the management of IVL following partial nephrectomy is a safe and efficient procedure with no significant impact on short or long-term renal function. Less complex renal tumors with lower RENAL scores are less likely to require postoperative SAE.

This study investigated the impact of an improved body positioning on the effectiveness of EDGE MP1000 robot-assisted laparoscopic partial nephrectomy. We compared clinical data from 39 patients who underwent the procedure at Zhujiang Hospital of Southern Medical University between November 2023 and May 2024. The control group (18 patients) received conventional positioning, while the experimental group (21 patients) received precise positioning, which included patient assessments, optimized positioning techniques, and enhanced nursing measures.

Background: Anaplastic lymphoma kinase (ALK)-rearranged renal cell carcinoma (ALK-RCC) is a rare molecularly defined tumor entity included in the fifth edition of the World Health Organization Classification of Tumors. It is characterized by rearrangement of the ALK gene with various fusion partner genes, which most commonly results in oncogenic fusion proteins leading to ALK activation.
Case Presentation: A 30-year-old Chinese man underwent partial nephrectomy for a left renal tumor measuring 5 cm in diameter.

Background: Gastric stump neoplasia is defined as a neoplasia that arises in the gastric remnant after at least 5 years of interval from the first gastric resection.
Aims: The aim of this study was to analyze 51 patients who underwent total and subtotal gastrectomy and multi-visceral resections in patients with gastric stump cancer.
Methods: The hospital records of 51 patients surgically treated for gastric stump cancer between 1989 and 2019 were reviewed.

Aim: Although the relief of ureteral obstruction seems to be a radical treatment for obstructive uropathy (OU), progressive kidney damage is the result because of the associated increased apoptosis and fibrosis. Therefore, it is urgent to find a complementary renoprotective therapy against partially obstructed uropathy cascades. Thus, this study investigated the renoprotective effects of both losartan (LOS) and zinc oxide nanoparticles (ZnONPs) in partial unilateral ureteral obstruction (PUUO).
