When renal cyst is small, patients can have no abnormal symptoms. However, when renal cyst grows bigger, it can induce a series of symptoms. What are the specific symptoms of Renal Cyst?
1. Symptoms of renal cyst representing discomforts or pain of waist or
stomach: It is caused by the growing renal cyst's pressure to its surrounding
tissues. Besides, the sac liquid can make cyst heavy and stain the cyst, which
also causes back pain. The characteristic of pain is dull pain, which regularly
represents one side or bilaterally and extends to waist, back and the lower
part. If renal cyst bleeds or is infected, it will aggravate dull pain. In
addition, if renal cyst is accompanied with stone or urinary obstacle of
clottage, it will cause renal colic.
2. Hematuria: it represents gross hematuria or microscopic hematuria, which
occurs periodically. Backache is usually aggravated after strenuous exercise,
wound or infection. The reason of haemorrhage is usually excess strain and
fracture of vessels on cyst wall, which is caused by increased pressure or
3. Abdominal mass: many Renal Cyst patients have a swollen kidney. Generally,
the bigger of the swollen kidney is, the poorer renal function will be.
4. Proteinuria: it will not be so serious, the 24-hour protein in urine will
be no more than 2 grams. And it will not develop into Nephritic Syndrome.
5. Hypertension: the growing Renal Cyst can press its surrounding tissues and
leads to the condition of renal ischemia, causing the increased secretion of
renin, which leads to Hypertension. When the renal function is abnormal, about
half of renal cyst patients have symptom of Hypertension and when the renal
function is declined, the incidence of Hypertension will increase too.
6. Declined renal function: the growing renal cyst can take up space and
press its surrounding tissues, which leads to progressive decline of renal
Renal Cyst patients should observe cyst on regular intervals when it is less
than 3cm diameters and avoid strenuous exercise or infection in their daily
Besides, they should also take a proper renal cyst diet which will not
aggravate the condition and delay the development of renal cyst. However, when
the cyst is larger than 3cm diameters, patients should take positive treatment
to protect the kidney from further decline.
