Left renal hydronephrosis is a condition in which urine cannot drain properly from the left renal pelvis due to various causes, leading to the accumulation of urine. Below are some possible causes:
1. Urinary tract obstruction: This is the most common cause. Conditions such as stones, tumors, congenital narrowing, inflammation, or scar tissue formation after injury may block urine outflow, leading to hydronephrosis.
2. Neurogenic factors: Neurological diseases or injuries, such as spinal cord injury, can affect the normal function of the bladder and urethra, causing voiding dysfunction and indirectly resulting in renal hydronephrosis.
3. Congenital abnormalities: Some individuals are born with structural problems in the urinary tract, such as abnormal ureteral valves or narrowing at the ureteropelvic junction. These congenital defects can also lead to hydronephrosis.
4. Tumors of the urinary and genital systems: For example, tumors of the left kidney or left renal pelvis may compress or obstruct the urinary tract, triggering left hydronephrosis.
5. Benign prostatic hyperplasia: When the prostate enlarges due to disease, it may compress the urethra and cause obstruction, impairing urine drainage and resulting in left renal hydronephrosis.
