Acute obstructive pyelonephritis due to pelvic organ prolapse: a case-based review of the literature.

Future Sci OA 2021 Mar 11;7(6):FSO696. Epub 2021 Mar 11.

Department of Urology, Hotel-Dieu de France, University of Saint Joseph, Beirut, Lebanon.

Pelvic organ prolapse (POP) can lead to acute bilateral obstructive pyelonephritis (ABOP) due to bilateral ureteral compression. When this occurs, conservative treatment through POP reduction, intravenous antibiotics and supportive care seems to provide an interesting option in the wait of definitive management of POP. The cornerstone of ABOP management, which is the emergent urinary drainage, seems to have many drawbacks in this context due to both technical and patient-related criteria, making it invasive and compromising patient safety and comfort in many settings.

Regulation and function of CX3CR1 and its ligand CX3CL1 in kidney disease.

Cell Tissue Res 2021 May 19. Epub 2021 May 19.

Institute for Molecular Medicine and Experimental Immunology, University Clinic of the Rheinische Friedrich Wilhelms University Bonn, Biomedical Center II, Venusberg Campus 1, 53127, Bonn, Germany.

Attraction, retention, and differentiation of leukocytes to and within the kidney are governed by chemokines. The chemokine CX3CL1 (fractalkine) and its receptor CX3CR1 are exemplary in this regard as they are highly expressed and further upregulated in a range of kidney diseases. CX3CL1 is chiefly produced by renal endothelium and tubular epithelium, where it promotes leukocyte attraction. Read More
