AI Article Synopsis
- A 64-year-old Japanese woman diagnosed with stage IVB cervical cancer experienced gross hematuria and renal dysfunction after chemoradiation therapy.
- A renal biopsy indicated rare complications: renal thrombotic microangiopathy (TMA) and tubulointerstitial nephritis (TIN), which are unusual for radiation nephropathy.
- The use of contrast-enhanced CT identified high radiation dose areas in the kidneys, demonstrating the need for a combined approach of clinical, pathological, and radiological assessments in diagnosing radiation nephropathy.
Article Abstract
A 64-year-old Japanese woman presented with gross hematuria and was diagnosed with stage IVB cervical cancer. Renal dysfunction was observed following chemoradiation therapy, and a renal biopsy revealed renal thrombotic microangiopathy (TMA) and tubulointerstitial nephritis (TIN), which are atypical features of radiation nephropathy. Contrast-enhanced computed tomography revealed wedge-shaped areas of high contrast, consistent with areas of high radiation dose in the kidneys, thus leading to the diagnosis of radiation nephropathy. This case underscores the importance of integrating clinical, pathological, and radiological findings for the diagnosis of radiation nephropathy, atypical renal biopsy findings, and a combination of TIN and renal TMA.

Acute Kidney Injury (AKI) is a significant medical condition characterized by the abrupt decline in kidney function.Low-intensity pulsed ultrasound (LIPUS), a non-invasive therapeutic technique employing low-intensity acoustic wave pulses, has shown promise in promoting tissue repair and regeneration. A novel LIPUS system was developed and evaluated in rat AKI models, focusing on its effects on glomerular filtration rate (GFR), blood urea nitrogen (BUN), serum creatinine (SCr), and the Notch1-Akt-eNOS signaling pathway.

Salidroside, a phenolic compound isolated from various plants, is the principal active constituent of Traditional Chinese Medicine known for its adaptogenic properties. Due to the challenging environment of species, such as high altitude, high radiation, drought, and hypoxia, the source of salidroside is scarce. However, numerous studies have shown that salidroside has a range of biological activities, including cardiovascular and central nervous system activity, and anti-hypoxia, anti-inflammatory, and anti-aging activities.

Renal fibrosis is a leading cause of chronic allograft nephropathy. While renal biopsy remains the gold standard for diagnosing fibrosis, it is an invasive procedure with potential for severe complications. Elastography, an emerging ultrasound imaging technique, appears to be a valuable tool for quantifying tissue stiffness, which correlates with fibrosis.
