PKD (Polycystic Kidney Disease) can be mistakenly diagnosed with
Hydronephrosis, Kidney tumor and Renal Hamartoma. Patients should perform the
following differential diagnosis to get their illness condition clear.
1. Differential diagnosis one: Hydronephrosis
Clinically, Hydronephrosis can have symptoms like back pain in sides,
abdominal mass and damage of kidney function. However, we can make clear
difference from PKD and Hydronephrosis through B ultrasound and IVU.
If B ultrasound shows: kidney enlargement, thinning in cortex and fluidity
shady area inside cortex, then it is Hydronephrosis.
2. Differential diagnosis two: Kidney tumor
It is rare to be seen that kidney tumors on both kidneys clinically. IVU
shows that kidney lesion, and kidney tumors are always on one side of kidney
poles. Unlike the cysts of Polycystic Kidney Disease, the cysts are broadly on
the kidneys.
Kidney tumors are more common in males over 40 years old.
3. Differential diagnosis three: Kidney Hamartoma
It is very difficult to tell PKD from kidney hamartoma through IVU. It also
has the character of multiple on both kidneys. Typical cases are difficult to be
diagnosed with B ultrasound and CT. Patients with tuberous sclerosis can be
easier to be identified.
Hope patients who are identified with PKD (Polycystic Kidney Disease) can
receive treatment as early as possible. Timely treatment can prevent PKD from
developing into kidney failure.
