What Does Renogram Do for Polycystic Kidney DiseaseRenogram, a diagnostic test for kidney disease, can also help show the information about kidneys and their function for Polycystic Kidney Disease patients. However, not all people with PKD need this scan in every physical examination.

When should PKD patients take this test?

Different from other chronic kidney diseases, PKD has numerous fluid-filled masses developing in commonly both kidneys. Generally speaking, these patients’ kidney function doesn’t decline in the early stage, because cysts are still small in size, but with the enlargement of kidney cysts, kidney function reduces gradually. Well then, some symptoms, such as high blood pressure, kidney pain, high creatinine level, kidney stone, etc, may occur. At this time, kidney renogram can be used to detect how kidneys are working.

How is renogram performed for kidney disease patients?

Kidney renogram is a nuclear medicine technology, in which a special radionuclide is injected into patients’ vein, usually in the arm. The blood is in charge of distributing the radionuclide throughout the body. Finally, this material is filtered out by kidneys.

During this process, doctor positions you on a flat table close to the gamma camera, so camera can obtain the best picture rapidly. Thereby, kidney renogram is able to give its result within 24 hours.

Are there risks in taking this test?

During this procedure, adverse reactions are rare. Only in some cases, patients may develop a rash around the injection site or feel dizzy or flushed. What’s more, as with other nuclear tests, renogram also has radiation risks, so pregnant or breast-feeding women are recommended to avoid it.

Warm prompt: For people with Polycystic Kidney Disease, they should notice may other factors before taking this test to reduce adverse reactions and guarantee its accuracy. For example, if you are taking diuretics or anti-hypertensive medications, stop them for two days before the exam. When you are suggested to do it, please consult the doctor in detail.
