Rationale: A horseshoe kidney is the most common congenital fusion abnormality in the kidney, occurring in approximately 1 in 400 live births. Several complications including renal malignancies, ureteropelvic junction obstruction, urolithiasis, vesicoureteral reflux, and hydronephrosis can occur in this patient population.
Patient Concerns: A 28-year-old woman was admitted to hospital because of chronic left low back pain. Microscopic hematuria was not seen. Computed tomography showed the horseshoe kidney and left hydronephrosis.
Diagnoses: On the basis of these findings and clinical manifestations, the final diagnosis was the horseshoe kidney with left renal hydronephrosis and inflammation.
Interventions: A retroperitoneoscopic nephrectomy on the left kidney was performed.
Outcomes: Histopathological examination of the specimen confirmed massive dilatation of the pelvicaliceal system and chronic pyelonephritic inflammation. The patient was discharged on the 7th postoperative day with no complications and no back pain. She remained well at 3 months with normal activity and good cosmetic result.
Lessons: Retroperitoneoscopic nephrectomy can be a safe and minimally invasive surgery for horseshoe kidney treatment.

A supernumerary kidney is a rare birth defect where an extra kidney is present. This extra kidney has its own separate outer covering, blood supply, and collection system. Normally, percutaneous nephrolithotomy (PCNL) is the treatment of choice for large kidney stones, but its ideal use for supernumerary kidneys is unknown.

C3 glomerulopathy (C3G), a rare kidney disease caused by dysregulation of alternative pathway complement activation, is characterized by glomerular C3 deposition, proteinuria, crescentic glomerulonephritis, and renal failure. The anti-C5 monoclonal antibody (mAb) drug eculizumab has shown therapeutic effects in some but not all patients with C3G, and no approved therapy is currently available. Here, we developed and used a triple transgenic mouse model of fast progressing lethal C3G (FHm/mP-/-hFDKI/KI) to compare the therapeutic efficacy of a bifunctional anti-C5 mAb fused to a functional factor H (FH) fragment (short consensus repeat 1-5 [SCR1-5]) and the anti-C5 mAb itself.

p97 (also known as valosin-containing protein, VCP) is a member of the AAA+ ATPase family and is intimately associated with protein quality control and homeostasis regulation. Therefore, pharmaceutical inhibition of p97 has been actively pursued as an anticancer strategy. Recently, p97 has emerged as an important pro-viral host factor and p97 inhibitors are being evaluated as potential antiviral agents.

Erythropoietin (EPO)-induced cellular signaling through the EPO receptor (EPOR) is a fundamental pathway for the modulation of cellular behavior and activity. In our previous work, we showed in primary human astrocytes that the multivalent display of EPO on the surface of semiconductor quantum dots (QDs) mediates augmented JAK/STAT signaling, a concomitant 1.8-fold increase in the expression of aquaporin-4 (AQPN-4) channel proteins, and a 2-fold increase in the AQPN-4-mediated water transport activity.

Background: The American Urologic Association (AUA) and the European Association of Urology (EAU) guidelines endorse percutaneous nephrolithotomy (PCNL) for symptomatic stones larger than 20 mm despite significant risks such as bleeding and urosepsis. Robotic pyelolithotomy (RPL) is emerging as an appealing alternative to PCNL, particularly for patients with anatomical variations like pelvic or horseshoe kidneys, malrotation, previous unsuccessful PCNL, and congenital renal anomalies such as ureteropelvic junction obstruction (UPJO).
Methods: A retrospective observational study was conducted involving patients from Miulli Hospital and A.
