The majority of patients with kidney failure requiring replacement therapy will need the support of hemodialysis during their journey with kidney failure. A reliable functioning vascular access is required to provide hemodialysis. This Core Curriculum reviews the major forms of vascular access (arteriovenous fistula, arteriovenous graft, and central venous catheter) as well as the planning, preparation, creation, use, and maintenance of vascular access, requiring a P-L-A-N (Patient ESKD Life-Plan first then Access Needs) for each patient. The end-stage kidney disease Patient Life-Plan focuses on a strategy for kidney replacement modalities, while the Access Needs are the corresponding dialysis access(es) and management plans. The Access Needs include a vessel preservation plan, creation plan, contingency (complications) plan, and access succession plan. Stenosis and thrombosis are common problems with arteriovenous accesses, and dysfunction and infection are common problems with central venous catheters. Underrecognized and underreported but potentially life-threatening situations include arteriovenous access rupture and high-output cardiac failure. Effective management of these and other vascular access problems requires a coordinated multidisciplinary effort that is patient centered while preserving vascular access.

Blood and Nerve Supply to the Kidney
Bloody Supply to the Kidneys:
The kidneys receive their blood supply from the renal arteries, which branch off from the abdominal aorta—the main artery supplying the abdomen and lower body. The renal arteries enter the kidneys at the hilum, a notch on the medial side of...
Renal Corpuscle
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...
Renal Clearance
Renal clearance refers to the volume of plasma cleared of a specific substance, such as creatinine, per unit of time. To measure clearance, urine samples are collected over a 24-hour period during each bladder voiding, followed by a single blood sample at the...
Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
Renal Drug Excretion: Overview
A nephron consists of two primary structures: the renal corpuscle and the renal tubule. The renal corpuscle contains the glomerulus, a network of capillaries where the first step of renal excretion, glomerular filtration, occurs. Blood pressure forces water, ions, and small molecules...
Renal Drug Clearance: Overview
Renal clearance can be calculated using different methods. One approach is to divide the urinary drug excretion rate by the plasma drug concentration. This method directly measures renal clearance, indicating the kidneys' efficiency in...
