Basics of the Kidney Cyst

Definition of the renal cyst

Renal cyst (simple takes cysts, SRC) is the most common problem in kidney diseases,If there are one or several enclosing bursal lumen in the kidneys,.At the same time,all the bursal lumen are full of fluid.We call these lesion as the renal cyst.

Characteristics of renal cysts

The reason of this disease is not clear now. The most majority of patients are adults,and is rare in children. Morbidity of the man is higher than woman. As the growth of the age, the Morbidity is rising, among the over 50 years people,maybe arrear 50% people with one or several renal cysts.

Clinical manifestations

Usually is asymptomatic, discovered when have a medical or imaging examination in other diseases by accident. Some patients will feel side "lower back pain symptoms”, often also is not because the renal cyst directly. Some kidney cyst happens to oppression ureter or renal calyx neck,so cause kidney seeper and secondary infection, then appear the waist pain, fever, symptoms of urinary tract infection.

Treatment and prognosis

Renal cyst progress is slow, the prognosis is well, no self-conscious symptom or oppression obstruction disease, not need the surgical intervention and oral drugs,aldo not affect the daily life, and just need the ultrasound review half a year or one year.

Treatment of the Kidney Cyst

Cyst diameter less than 4 cm, calyces obvious compression of the renal pelvis, no infection, malignant transformation, high blood pressure, and symptom is not obvious, only need to observation closely, regular B ultrasonic review.(1) Puncture fluid treatment and hardener1. This method is suitable for the cyst diameter is larger than 4cm , with symptomatic, through inspection exclude malignant infection patients.

2. Used hardener commonly, tetracycline, lock, 95% alcohol, 95% glucose phosphate.

3. Contraindicated and skin infections, with the severe bleeding tendency patients.

4. Complications were bleeding, infection, hemopneumothorax, laceration of kidney, arteriovenous fistula, urinary cyst and hardening agent extravasation of kidney stimulation and damage to the surrounding tissue.

(2) Puncture fluid and antibiotics

1. Indications gets 4 cm diameter when renal cyst with pouch. Under ultrasound guided puncture fluid, according to the likely infection strains and sensitive antibiotics.

2. The taboo card is the same as the complications and puncture add hardener.

(3) The surgery

1. The indications (method have open surgery and laparoscopic)

(1) cyst infection, puncture fluid and antibiotic treatment is failure. (2) cyst malignant change. (3) puncture add hardener treatment of insomnia. (4) large renal cyst.

2. Surgical options

(1) cyst unroofing, applicable to the vast majority of patients who with renal cyst; (2) the kidney excision,this way is suitable to malignant degeneration or cystic kidney cyst.

3. The postoperative complications usually have infection, bleeding, urinary fistula.

Symptoms of the Kidney Cyst

The most of renal cyst are asymptomatic. Some patients because of cyst itself and the capsule higher internal pressure, infection and appear the following symptoms

Diagnosis of the Kidney Cyst

The first choice is Medical routine abdominal ultrasound (or colour to exceed), what will found the renal cyst also can is a means of regular review. If the ultrasound results cannot accurately judge cyst properties,then should check abdominal enhanced CT.The key of dignose is to identify the renal cyst and cystic tumor. The former under ultrasound, computed tomography (CT) assumes the circular uniform liquid dark space, without reinforcement, thin wall and back wall echo enhancement, cyst and renal parenchyma boundary is clear and smooth; The latter cystic wall is irregular, sac contents material which is like tumor. Is also necessary to identification calyces diverticulum, enhanced computed tomography (CT) or intravenous urography angiography (IVP) is more effective.

A few common concepts:

"High density renal cyst" refers to some of the smaller renal cyst under scan CT images showed higher or equal to the density of kidney, is different from the common renal cysts, easy to confused with renal small tumors. Its high density derived from high protein or fluid with contain blood composition.

"Multiple renal cyst and polycystic kidney" : one kidney can appear a number of simple renal cyst at the same time, but between normal renal cortical cyst,there is no connection between cyst and renal function without damage, so called multiple renal cyst; Polycystic kidney is congenital genetic disorders, kidney were the cyst is like a bubble, almost can’t see normal kidney tissues, renal failure in the earlier time.

Diet for Kidney Cysts

Diet for the disease is crucial for its treatments and prognosis. But before anything, realizing it matters too.

Kidney Cysts refer to round, thin, clear cysts full of watery fluid on kidneys. Simple renal cysts are the most commonly seen. The disease usually presents no symptoms so requires no treatment. Most of the patients live with the disease for the rest of their lives without even noticed. Renal cysts have many types including PKD (Polycystic Kidney Disease) and some others. PKD could lead to Renal Failure, but simple renal cyst probably won't.

Why diet matters?

Unhealthy dietary habit aggravates the disease but renal-friendly diet could possibly stop it from progressing. So, what's about the detailed diet guidelines for those patients?

Firstly, the amount

Neither eating too much nor consuming too little is beneficial, meaning the amount is vital. The recommended dietary principle is eating small meals.

Secondly, infections are fatal to patients with Kidney Cysts

Don't eat foods that may cause diarrhea or gastrointestinal diseases, sometimes. Infections passing from those foods could trigger cyst infections, which would become seriously and require surgery.

Foods low in sodium, phosphorus, protein and potassium etc. should be consumed, this is pretty same as any other kidney diseases. Animal plucks become the last thing to consume since they could pose extra pressure on damaged kidneys. Another thing needs you bear in mind is that high blood pressure usually attacks in patients with Kidney Cysts; therefore, anti-hypertensive drugs would be used in the initial stage. Of course, some certain fresh vegetables and fruits could work well for lowering high blood pressure, but ask your dietitian before consuming any of them.

Taking a good rest is as important as eating right foods. Plus, intensive exercises may lead to the ruptured cysts; therefore, strenuous activity should be definitely avoided.

If the patients suffer from serious pain or present blood in urine, timely treatments should be adopted. Don't wait until everything's too late!
