Influence of age on gender-related differences in acute kidney injury after minimally invasive radical or partial nephrectomy.

Surg Endosc 2021 Jun 11. Epub 2021 Jun 11.

Department of Anesthesiology and Pain Medicine, Anesthesia and Pain Research Institute, Yonsei University College of Medicine, 50-1 Yonsei-ro, Seodaemun-gu, Seoul, 03722, Republic of Korea.

Background: Female gender is known to be protective against acute kidney injury (AKI) after radical or partial nephrectomy and estrogen is considered a protective factor. If estrogen is a major contributor to the protective effects of female gender against renal injury, these protective effects may be diminished in postmenopausal women. Therefore, this retrospective study investigated the influence of female age on gender-related differences in AKI after minimally invasive radical or partial nephrectomy. Read More

Controlled ovarian stimulation therapy as a potential risk for the development and progression of renal cell carcinomas: A case report and literature review.

Mol Clin Oncol 2021 Jul 23;15(1):140. Epub 2021 May 23.

The Yale Larynx Laboratory, Department of Surgery, Yale School of Medicine, New Haven, CT 06510, USA.

Renal Cell Carcinoma (RCC) is the most common type of cancer in the kidney and is mostly asymptomatic. Previous studies have supported the important role of sex hormones in RCC pathophysiology and that targeted hormone receptor therapy, such as estrogen receptor targeting, is a promising treatment strategy. However, to the best of our knowledge, it remains unknown whether hormonal therapy, such as controlled ovarian stimulation for fertilization, serves a role in the development and progression of RCC.

Characterization of the Peritumoral Atrophic Band and Nonneoplastic Renal Parenchyma in Radical Nephrectomy Specimens.

Am J Clin Pathol 2021 Jun 2. Epub 2021 Jun 2.

Department of Pathology, Medical College of Wisconsin, Milwaukee, WI, USA.

Objectives: Pathologic evaluation of nonneoplastic renal parenchyma in nephrectomy specimens is important for identifying chronic kidney disease and diabetic nephropathy, but increasing utilization of partial nephrectomies has led to less-sampled nonneoplastic parenchyma. The sampled tissue is often composed predominantly of the peritumoral atrophic band (PAB) directly adjacent to the tumor. We sought to determine the characteristics of the PAB and whether it could be used to reliably assess kidney pathology, including diabetic nephropathy. Read More
