I. Pain in the waist or stomach.
The tension of renal capsular surface will increase with the expansion of the kidneys, by which the renal pedicle and the adjacent organs will be stretched, and finally make you feel pain. In addition, the cysts make too much water remain in the kidneys and make the kidneys become heavy and be dropped down, which is also a cause of the pain.
Pain caused by kidney cyst is dull, and it is always in a certain part of the body with the possibility of one side or two. However, the pain will be sharpened if capsule hemorrhage or infection happen, and renal colic can be arose by merged stone and clottage.
II. Hematuria.
Both microscopic hematuria and gross hematuria are possible, and they can present periodically. Once hematuria appears, the pain in the waist can be aggravated and itself can also be sharpened by strenuous exercise, wound as well as infection. Hematuria is mainly a consequence of rupture of the artery under the wall of cyst and infection.
III. Lump in the abdomen.
60%-80% of the patients can have tumid kidneys after getting renal cyst and this is also one of the direct reasons which lead people to go to the hospital. Generally speaking, the bigger the cyst is, the severer the disease will be.
