What Is the Renal Papilla?
The base of the renal pyramid faces the cortex, the tip is obtuse, and it faces the sinus, called the renal papilla. Sometimes 2 to 3 cones form a kidney papilla. Each kidney has 7 to 12 renal nipples. There are 10 to 25 small holes in the kidney nipples, called nipple holes, which are opened in the small kidneys and are the channels for urine to flow into the kidneys.

- The base of the renal pyramid faces the cortex, the tip is obtuse, and it faces the sinus, called the renal papilla. Sometimes 2 to 3 cones form a kidney papilla. Each kidney has 7 to 12 renal nipples. There are 10 to 25 small holes in the kidney nipples, called nipple holes, which are opened in the small kidneys and are the channels for urine to flow into the kidneys.
Renal nipples
- Renal burr is a funnel-shaped membranous tube surrounding the renal papilla. Sometimes a small kidney can wrap around 2 to 3 kidney papillae, so there are about 7 to 8 kidney kidneys per kidney. Adjacent kidney calyces merge into kidney calyx.
- On the deep side of the renal medulla, a funnel-shaped membrane tube that surrounds the nipple of the kidney is called a small kidney. The small kidney is inwardly connected to the large kidney. Sometimes a small kidney can wrap around 2 to 3 renal nipples, so the number of small kidney cavities is less than the number of renal nipples. Urine generated in the kidney enters the small kidney through the sieve area, and then enters the large kidney through the small kidney. The renal excretion angiography or retrograde angiography mainly observes the shape of the renal papilla and renal stump, which is meaningful for the diagnosis of certain kidney diseases.
Kidney Papilla II
- Large kidney tubes are called larger kidney tubes. The kidney is connected to the renal pelvis. Nephrogenic urine passes from the kidney to the kidney. From the kidney to the renal pelvis. Renal excretion angiography or retrograde angiography mainly observes the shape of large kidney, small kidney, or renal papilla, which is meaningful for the diagnosis of certain diseases of the kidney.
Renal nipples III, nephritis
- Diseases caused by glomerular inflammation. Because the main lesion is in the glomerulus, it is also called glomerulonephritis to distinguish it from pyelonephritis and interstitial nephritis. Glomerulonephritis (hereinafter referred to as nephritis) is a group of primary glomerular diseases with clinical manifestations such as oliguria, hematuria, and proteinuria, often accompanied by edema, hypertension, and renal impairment. It is clinically divided into acute, aggressive, chronic and occult. The cause has not been identified, it is generally believed that the body's immune response to certain pathogenic factors, rather than the direct infection or damage to the kidneys caused by these factors. The most common cause is the immune response caused by beta hemolytic streptococcal group A infection. The duration of acute nephritis is within 6 months. Acute nephritis has no cure and can develop into chronic nephritis. But most cases of chronic nephritis have no obvious acute phase. Nephritis is more common in children and adolescents. The main clinical manifestations are edema (usually starting from the face and extending to the whole body), decreased urine output, and gross hematuria. Urinalysis showed proteinuria, hematuria, and cast urine. Blood pressure increased to varying degrees. Acute nephritis should rest in bed and be given symptomatic treatment such as diuresis and antihypertensive treatment. If symptoms of acute infection can be treated with antibiotics. Chronic nephritis can be treated with corticosteroids, immunosuppressive agents and traditional Chinese medicine. Active prevention of streptococcal infections is the key to preventing nephritis.
