What Is Renal Ptosis?

Renal droop means that the position of the kidneys moving with breathing activity is beyond the normal range, which causes the urinary system and other symptoms. Normal kidneys generally have a range of movements within 3 cm with breathing activity.

Basic Information

English name

nephroptosis

Visiting department

Nephrology

Common causes

Decreased abdominal pressure

Common symptoms

Low back pain, frequent urination, urgency, bloating, nausea, vomiting, decreased appetite, etc.

Causes of renal ptosis

The kidneys are located in the kidney sockets on both sides of the thoracolumbar. Due to the strong longitudinal muscles of the back and the fixation of the abdominal organs, the kidneys are generally not displaced too much. However, because of a potentially loose space beneath the periprenal fat sac, when the abdominal pressure decreases, the kidney may shift downwards and cause the kidney to sag.

Clinical manifestations of renal ptosis

Urinary system symptoms

Most patients have back pain. Some patients have symptoms of chronic urinary tract infections, most of which are bladder irritation such as frequent urination and urgency. A few cases are accompanied by a history of low or repeated fever. Occasionally, lower limb edema and other manifestations.

2. Digestive system symptoms

Due to the traction of the abdominal plexus during renal activity, it often causes gastrointestinal symptoms, such as abdominal distension, nausea, vomiting, and decreased appetite.

3. Neurological symptoms

These patients are often nervous, with insomnia, dizziness, and memory loss.
The above symptoms are not necessarily proportional to the degree of renal sagging. Sometimes the degree of sagging is not severe, but it can cause more obvious symptoms.

4. Pain in the kidney area

In some cases, the kidney area has throbbing pain. Due to the lower anatomy of the right kidney, the kidney socket is shallow. Once the liver is impacted, the right kidney will sag more than the left.

Droop test

1. X-ray inspection

Intravenous pyelography must be followed by a standing radiograph to understand its activity. But because the standing film must be carved immediately when standing, otherwise the kidneys cannot be displayed after the contrast agent is exhausted. In some patients, because the kidneys have not drooped to their usual position, sagging may not be seen in intravenous pyelography. However, the diagnosis of kidney droop can still be made from symptoms, physical examination and ultrasound examination.

2. Ultrasound

Half an hour after the head is lowered, the position of the kidney and the position of the kidney after exercise are checked by ultrasound. The distance between the two is the degree of kidney activity.

3. Head down test

Patients were instructed to lie down with their heads high and supine for 3 days (the height of a brick's long diameter can be raised at the foot of the bed). Before going to bed, during and after bedtime, determine the urinary routine or hourly urinary red blood cell excretion rate, and observe whether the symptoms ease . If the red blood cells in the urine are significantly reduced or disappeared after sleep, and the symptoms are alleviated, the diagnosis of renal ptosis is supported. If the symptoms are not relieved, the renal ptosis may be excluded.

4. Water injection test

To determine if the patient's low back pain comes from the kidney, a cystoscopic ureteral cannula can be injected into the renal pelvis until the waist feels painful. For example, if the nature and location of pain are similar to those during normal attacks, the diagnosis is positive, and if it is not similar, it is not a symptom caused by renal sag.

Diagnosis of droop

Most of them are diagnosed with backache, kidney disease and other symptoms when they seek medical attention due to backache, chronic urinary tract infection, and repeated hematuria.

Renal droop treatment

Non-surgical treatment

Exercise abdominal and lumbar muscles, increase abdominal pressure to resist kidney sagging. It can be used with internal medicines such as Buzhong Yiqi Pills, Liuwei Dihuang Pills, etc. In addition, some drugs that improve protein synthesis such as Nandrolone phenylpropionate can be used. The method of exercising the abdominal muscles can be used for sit-ups, straight leg lifts and other training. You can also use kidney pads and waistbands.

2. Surgical treatment

(1) Injection therapy Inject quinine, gelatin or sponge-like preparations around the kidneys to cause perinephric adhesions to stabilize the kidneys.

(2) In addition to surgical fixation, in addition to making small incisions, quinine and gelatin preparations are inserted into the periphery of the kidney to cause perinephric adhesions. The kidney can be completely separated from the renal fat by surgery and then fixed in the appropriate anatomical position by various methods on.
