Most kidney cysts (fluid filled mass) are classified as “simple” and are very common. They are generally benign, and found incidentally during an ultrasound, CT or other scan performed for some other reason. Most often these simple cysts can be left alone with no worries. Rarely, a simple kidney cyst can enlarge enough to cause pain, and these can be treated by needle drainage or more permanently with surgery (usually laparoscopy with small incisions.) Some kidney cysts are classified as “complicated” and might have more worrisome or malignant features that warrant more comprehensive exams and treatments including surgery. Very rare are multi-cystic and poly-cystic kidneys that can in worst cases cause kidney failure requiring dialysis or kidney transplant.

- Are kidney cysts treated with surgery?
What test should be performed if I have blood in my urine?
Clearly visible and microscopic hematuria (blood in the urine) requires evaluation. The upper urinary tract should be imaged, and cystoscopy should be done if there is hematuria in the absence of infection. A comprehensive evaluation is necessary entailing of upper tract (kidneys and ureters) imaging, cystoscopy and urine cytology.
What is a ureteral stent?
A ureteral stent is a thin, hollow tube that is put in the ureter to help urine pass from the kidney into the bladder. Ureters are the tubes that connect the kidneys to the bladder. A ureteral stent is put in when something is blocking the ureter. The blockage can be caused by problems such as a kidney stone, scar tissue, a tumor or an infection.
A stent may be needed after surgery on the ureter or kidney. A blocked ureter can cause urine to back up into the kidneys. This can hurt the kidneys. It can also cause an infection. The doctor will place the stent by guiding it through the urethra. The urethra is the tube that carries urine from the bladder to outside the body. Then the doctor will guide the stent through the bladder and ureter and into the kidney. The doctor will make sure one end of the stent is in the kidney and the other end is in the bladder. No cuts are made in the body.A ureteral stent may be left in place for several days or for as long as several months. The longer the stent is in the ureter, the more likely it is to cause side effects. Side effects include: A need to urinate more often. A sudden need to urinate. A feeling that the bladder is not completely empty after urinating. A small amount of blood in the urine. Some pain in the belly, side or back. Infection.
