<br>This concept introduces the <b>KidnoPod</b>, an innovative auxiliary renal support device designed to be implanted in the scrotum after orchiectomy. The device uses nano-filtration and smart regulation to assist kidney function in patients with chronic kidney disease (CKD). The scrotal cavity offers vascular access, temperature stability, and surgical convenience, making it a promising site for a minimally invasive renal support system. The KidnoPod aims to reduce dialysis dependency and extend renal function in high-risk patients.
