10 Symptoms of Hydronephrosis
Reviewed: Dr. Gromatzky
Cause #7: Tumors
A tumor is a mass of abnormal growing tissue that can be benign, malignant, or precancerous. Hydronephrosis may occur if a tumor presses against part of the urinary system causing obstruction. This can be seen in tumors that occur in the pelvis such as cervical cancer, ovarian cyst, bladder cancer, colon cancer, prostate cancer, and more.
Some studies have also used the severity of hydronephrosis to correlate with the invasiveness of the tumor. One research team concluded that hydronephrosis that is more than a grade 2 is associated with bladder cancer recurrence and non-organ-confined ureteral cancer.
