Causes And Treatment For Blood In Urine For PKDMore than 90% PKD patients will have cyst bleeding or blood in urine. Often it is spontaneous, but it can also occur after strenuous activities or physical traumas. In case of blood in urine, the first step is to make clear the underlying cause and seek proper treatment as soon as possible.

There are mainly 3 causes of blood in urine for PKD patients. Blood in urine is called hematuria in clinic.

1. Cyst bleeding. Patients can have sudden pains, but there is no gross hematuria.

2. Cyst rupture. If the ruptured cyst is connected with the urinary tract, it can cause blood in urine which can be seen with naked eyes. It is gross hematuria.

3. Renal capsule. The continuous enlargement of renal cysts can stretch the renal capsule and cause rupture of blood vessels on the cyst.

Usually hematuria can disappear after 2-7 days. If not, proper treatment should be sought as soon as possible to prevent further harms to kidney functions when the exact cause of blood in urine is made clear, proper treatment should be sought .

Treatment for hematuria in PKD cases is relatively more difficult than caused by other diseases. The blood in urine can disappear within 4-8 days after taking medicines, but it will re-appear after a period of time. Long term poorly controlled hematuria can cause anemia, sharp decline of platelet, poor clotting mechanism and in serious conditions it can cause shock or even death.

Blood in urine can cause infections in the kidney and patients can have high fever, swelling, kidney enlargement or even sharp decline of kidney functions. If not well controlled, kidney infection can in turn worsen blood in urine. Therefore effective prevention and early treatment for infections after blood in urine should be sought.

The curative effects of Chinese medicines are good for PKD patients with repeated blood in urine, but it takes relatively long time to take effects, but its curative effect is durable and blood in urine is not easy to relapse.

If the patient has begun dialysis and has recurrent hematuria, dialysis without heparin should be adopted to reduce the bleeding tendency. If bleeding is very serious, angiography, selective renal artery embolization or nephrectomy can be considered.
