Dr. Yang Ziqi
The condition of bilateral hydronephrosis combined with ureteral dilation is usually quite serious. This situation often indicates that the degree of hydronephrosis is significant and the duration of the obstruction may be prolonged. 1. Degree of hydronephrosis: Bilateral hydronephrosis accompanied by ureteral dilation typically indicates that the hydronephrosis has reached a considerable level, which may adversely affect kidney function. 2. Duration of hydronephrosis: Prolonged hydronephrosis may lead to gradual loss of kidney function and even progress to renal failure. 3. Possible causes: This condition may be caused by various factors, such as urinary tract obstruction, intrinsic ureteral pathology, or lesions surrounding the kidney. Prompt diagnosis and treatment of these underlying causes are essential to prevent further renal damage.
