What are the symptoms of hydronephrosis?

Hydronephrosis is a common kidney disease primarily characterized by the accumulation of urine within the kidney, preventing its normal excretion. Common symptoms include:

1. Back pain or abdominal discomfort: This is one of the most common symptoms. The pain may be persistent or intermittent and sometimes radiates to the groin or thigh.

2. Frequent urination, urgency, or painful urination: Hydronephrosis can also cause urinary tract irritation symptoms such as frequent urination, urgency, and dysuria, which may result from the accumulated fluid pressing on the urethra or bladder.

3. Hematuria: Blood in the urine, visible to the naked eye or detectable only under a microscope, is an important indicator of hydronephrosis.

4. Fever: If hydronephrosis is accompanied by an infection, the patient may develop a fever.

5. Weight gain: Fluid retention in the body may lead to sudden weight gain.

6. General symptoms: Such as nausea, vomiting, and fever, which result from the buildup of toxins in the body due to impaired kidney function.

Not all of the above symptoms necessarily occur simultaneously, and some symptoms may also be indicative of other diseases. Therefore, if any of these symptoms occur, prompt medical attention is advised.
