ICD-10: N13.39

Hydronephrosis is a medical condition characterized by the swelling of a kidney due to a build-up of urine. This occurs when there is an obstruction in the urinary tract that prevents urine from draining properly from the kidney to the bladder. The ICD-10-CM code N13.39 specifically refers to "Other hydronephrosis," which encompasses cases of hydronephrosis that do not fall under more specific categories defined by other codes.

Clinical Description of Hydronephrosis

Definition and Pathophysiology

Hydronephrosis can be classified into two main types: congenital and acquired. Congenital hydronephrosis is present at birth and often results from anatomical abnormalities, such as ureteropelvic junction obstruction. Acquired hydronephrosis can develop due to various factors, including kidney stones, tumors, or strictures in the urinary tract.

The condition leads to increased pressure within the kidney, which can cause damage to renal tissue if not addressed promptly. Symptoms may vary depending on the severity and underlying cause but can include flank pain, urinary tract infections, and changes in urinary output.

Symptoms

Common symptoms associated with hydronephrosis include:
- Flank pain: Often described as a dull ache or sharp pain on one side of the back.
- Nausea and vomiting: These may occur due to pain or as a response to kidney dysfunction.
- Urinary changes: This can include increased frequency, urgency, or difficulty urinating.
- Fever: May indicate an infection associated with the obstruction.

Diagnosis

Diagnosis typically involves imaging studies such as:
- Ultrasound: The first-line imaging modality to assess kidney swelling.
- CT scan: Provides detailed images and can help identify the cause of obstruction.
- MRI: Occasionally used for further evaluation, especially in complex cases.

Treatment

Treatment for hydronephrosis focuses on relieving the obstruction and may include:
- Surgical intervention: Such as ureteral stenting or nephrostomy to bypass the obstruction.
- Medications: To manage pain or treat infections.
- Observation: In mild cases where the obstruction resolves spontaneously.
