Primary Retroperitoneal Lymph Node Dissection for Clinical Stage II A/B Seminomas: A Systematic Review and Meta-Analysis.

Introduction: Chemotherapy and radiation therapy are considered standard treatments for stage II seminoma patients; however, these therapies are associated with long-term toxicities. Recently, retroperitoneal lymph node dissection has emerged as an alternative strategy, and the first three phase II trials were published in 2023 with promising results. The present study conducted a systematic review and meta-analysis to evaluate this surgery as an alternative treatment for stage IIA/B seminoma patients.

Renal cell carcinoma with tumor thrombus in the lower cava vein reaching the right atrium - Case report and brief review of the literature.

Approximately 15% of cases of renal cell carcinoma (RCC) can invade the inferior vena cava, leading to the formation of a thrombus inside it, which can reach the cardiac chambers in up to 1% of cases. This article reports a case of RCC with venous thrombus that reached the right atrium. The patient underwent radical nephrectomy with lymphadenectomy and tumor thrombectomy with extracorporeal circulation associated with hypothermia, without total cardiac arrest.

Port-Site Metastasis of Undiagnosed Pancreatic Adenocarcinoma After Laparoscopic Radical Prostatectomy: Case Report and Literature Review.

Laparoscopic port-site metastases remain rare for urologic tumors, despite the increasing use of laparoscopic techniques on the approach of urologic malignancy. Herein, we report a case of port-site mass after laparoscopic radical prostatectomy whose immunohistochemistry demonstrated metastasis from a pancreatic lesion. A 62-year-old man presented to our ambulatory clinic with an elevated prostate-specific antigen (PSA) of 7.

The relationship between renal warm ischemia time and glomerular loss. An experimental study in a pig model.

Purpose:: To investigate the glomerular number after different warm ischemia times.

Methods:: Thirty two pigs were assigned into four groups. Three groups (G10, G20, and G30) were treated with 10, 20, and 30 minutes of left renal warm ischemia.

Glomerular loss after arteriovenous and arterial clamping for renal warm ischemia in a swine model.

Purpose:: To evaluate the glomerular loss after arteriovenous or arterial warm ischemia in a swine model.

Methods:: Twenty four pigs were divided into Group Sham (submitted to all surgical steps except the renal ischemia), Group AV (submitted to 30 minutes of warm ischemia by arteriovenous clamping of left kidney vessels), and Group A (submitted to 30 minutes of ischemia by arterial clamping). Right kidneys were used as controls.

Penile primary melanoma: analysis of 6 patients treated at Brazilian National Cancer Institute in the last eight years.

Purpose: To describe our experience in treating penile melanoma in 06 patients followed at our institution.

Materials And Methods: Between 2004 and 2012 six consecutive patients with penile melanoma were treated at our Institution. Stage of the disease was classified according to the 2002 AJCC pathologic system.
