What does B-ultrasound showing bilateral renal separation mean?

Bilateral renal separation observed on B-ultrasound refers to the finding of separation in the renal collecting systems of both kidneys during ultrasound examination. This usually indicates fluid accumulation within the kidneys, possibly suggesting hydronephrosis. The cause of bilateral renal separation may be physiological, such as during fetal development or due to urinary retention, in which case the fluid accumulation is typically mild and resolves after urination. It may also be pathological, caused by kidney diseases (such as stones, adhesions, or tumors) that obstruct the normal drainage of urine, leading to fluid buildup in the kidneys. If the separation results in renal pelvis dilation exceeding one centimeter, a diagnosis of hydronephrosis can be made. Patients with this condition may experience changes in urination, such as straining to urinate, dribbling, or painful urination. Depending on the underlying cause, individuals should consult a physician for appropriate evaluation and management.
