Here is a comprehensive overview of the kidney and diaphragm anatomy, including their relationship to each other:

Kidney Anatomy

Location & Position

The kidneys are paired retroperitoneal organs located on either side of the vertebral column, at the level of T12 to L3 vertebrae.
The right kidney sits slightly lower than the left because the liver occupies space above it.
Each kidney is roughly 10–12 cm long, 5–6 cm wide, and 3–4 cm thick, weighing about 120–170 g.

Structure

Component	Description
Cortex	Outer region; contains glomeruli and proximal/distal tubules
Medulla	Inner region; contains renal pyramids and loops of Henle
Renal Pelvis	Funnel-shaped cavity collecting urine from calyces
Hilum	Medial indentation where renal artery, vein, and ureter enter/exit
Renal Capsule	Fibrous outer covering of each kidney

Blood Supply

Renal artery (branch of abdominal aorta) → segmental arteries → interlobar → arcuate → interlobular arteries → afferent arterioles → glomeruli
Renal vein drains into the inferior vena cava (IVC)

Function

Filtration of blood and urine production
Regulation of blood pressure (renin-angiotensin system)
Regulation of electrolytes, acid-base balance
Erythropoietin and vitamin D production

Diaphragm Anatomy

Location & Structure

The diaphragm is a dome-shaped musculotendinous sheet separating the thoracic cavity (above) from the abdominal cavity (below).
It is the primary muscle of respiration.

Key Openings (Hiati) in the Diaphragm

Opening	Level	Structures Passing Through
Caval hiatus	T8	Inferior vena cava, right phrenic nerve
Esophageal hiatus	T10	Esophagus, vagal trunks
Aortic hiatus	T12	Aorta, thoracic duct, azygos vein

Muscle Parts

Sternal part — attaches to the xiphoid process
Costal part — attaches to ribs 7–12
Lumbar part — attaches via crura to lumbar vertebrae (L1–L3)

Relationship Between the Kidneys and Diaphragm

This is clinically very important:

The upper poles of both kidneys are in direct contact with or very close to the posterior surface of the diaphragm.
The right kidney's upper pole is at the level of the 12th rib, and the left kidney's upper pole may reach as high as the 11th rib — both lying just beneath the diaphragm.
The diaphragm separates the kidneys from the pleural cavities above.

Clinical Relevance

Percutaneous nephrostomy or kidney biopsies of the upper pole carry a risk of pneumothorax because of the close proximity to the diaphragm and pleural space.
Subphrenic (subdiaphragmatic) abscesses can arise from kidney infections spreading upward.
Deep breathing moves the diaphragm, which in turn moves the kidneys 2–3 cm inferiorly — this is used in ultrasound to visualize the kidneys.
In diaphragmatic hernia, abdominal organs (sometimes the kidney) can herniate into the chest.

The kidneys sit just below the diaphragm in the retroperitoneal space, making them direct neighbors to this major respiratory muscle.

Kidney has diaphragm called nephrin

You are correct in connecting nephrin and diaphragm — but the full term is the slit diaphragm, and nephrin is the key protein that forms it. Here is a clear explanation:

The Slit Diaphragm — The Kidney's Own "Diaphragm"

What is it?

The slit diaphragm is a thin, specialized filtration membrane found inside the kidney — specifically in the glomerulus (the tiny filtering unit of the kidney). It is NOT the same as the thoracic diaphragm muscle.

Think of it as the kidney's own microscopic "filter gate."

Where is it exactly?

Inside each kidney, there are about 1 million nephrons. Each nephron has a glomerulus — a tiny ball of capillaries. Surrounding these capillaries are specialized cells called podocytes, which have long finger-like extensions called foot processes.

The gap between neighboring foot processes is called the filtration slit, and the thin membrane that bridges this gap is the slit diaphragm.

What is Nephrin?

Feature	Detail
Full name	Nephrin (encoded by gene NPHS1)
Type	Transmembrane protein
Location	Slit diaphragm between podocyte foot processes
Function	Acts as a structural scaffold of the slit diaphragm; controls what passes through the filtration barrier
Partner protein	Podocin (NPHS2) — works alongside nephrin

Nephrin essentially zips together the edges of adjacent foot processes, forming the slit diaphragm structure.

Why is Nephrin Clinically Important?

Mutations in the NPHS1 gene (nephrin) or NPHS2 gene (podocin) disrupt the slit diaphragm, causing massive protein leakage into urine (proteinuria).

This leads to hereditary nephrotic syndrome, characterized by:

Heavy proteinuria (>3.5 g/day)
Low blood albumin (hypoalbuminemia)
Edema (swelling)
High cholesterol

(Harrison's Principles of Internal Medicine, 21st Ed., p. 8394)

Summary

Term	What it is
Diaphragm (thoracic)	Muscle separating chest and abdomen
Slit diaphragm (kidney)	Microscopic filtration membrane in the glomerulus
Nephrin	The key protein that forms the slit diaphragm

So to directly answer your question: the kidney's "diaphragm" is the slit diaphragm, and nephrin is the critical protein that makes up this structure.
