Hydrocele may cause urinary protein. Usually the milder condition of hydronephrosis will not cause urinary protein. However, if the hydronephrosis is more serious and causes kidney function damage, urine protein may appear.
Hydronephrosis is often caused by obstruction of the urinary tract, the more common are ureteral stones, urethral stenosis, tumors and so on. This results in obstruction of urine outflow, which leads to abnormal accumulation of urine in the kidneys, resulting in hydronephrosis. It often manifests as low back and abdominal pain, nausea, vomiting, etc., usually without proteinuria.
However, more serious hydronephrosis may cause impaired renal tubular function, as well as complications such as renal failure, which may also result in proteinuria.
In conclusion, hydronephrosis may cause proteinuria, but proteinuria may also be caused by other reasons. It is recommended that the patient consult a doctor in time, complete the relevant examination, clarify the cause, and standardize the treatment.
