ICD-10: N28.85

Clinical Description of Pyeloureteritis Cystica (ICD-10 Code N28.85)

Overview
Pyeloureteritis cystica is a rare condition characterized by the presence of cystic lesions in the renal pelvis and ureter. It is classified under the ICD-10 code N28.85, which falls within the broader category of "Other disorders of kidney and ureter, not elsewhere classified" (N28) [1][4]. This condition is often associated with chronic irritation or inflammation of the urinary tract, which can lead to the formation of cysts.

Etiology and Pathophysiology
The exact cause of pyeloureteritis cystica is not well understood, but it is believed to be related to chronic urinary obstruction, infection, or irritation. Factors such as recurrent urinary tract infections (UTIs), kidney stones, or anatomical abnormalities may contribute to the development of this condition. The cysts that form can vary in size and may be asymptomatic or lead to complications such as obstruction or infection [2][3].

Symptoms
Patients with pyeloureteritis cystica may present with a range of symptoms, including:
- Flank pain or discomfort
- Hematuria (blood in urine)
- Urinary frequency or urgency
- Dysuria (painful urination)
- Possible signs of urinary tract infection, such as fever or chills [5][6].

In some cases, the condition may be discovered incidentally during imaging studies performed for other reasons.

Diagnosis
Diagnosis of pyeloureteritis cystica typically involves imaging studies such as:
- Ultrasound: This can help visualize cystic structures in the kidneys and ureters.
- CT Scan: A more detailed imaging technique that can provide information about the size and extent of cysts and any associated complications.
- MRI: Occasionally used for further evaluation, especially in complex cases.

Laboratory tests, including urinalysis and urine cultures, may also be performed to rule out infections or other underlying conditions [7][8].

Management and Treatment
Management of pyeloureteritis cystica focuses on addressing the underlying causes and alleviating symptoms. Treatment options may include:
- Antibiotics: If a urinary tract infection is present.
- Surgical intervention: In cases where cysts cause significant obstruction or complications, surgical options may be considered to remove the cysts or correct anatomical abnormalities.
- Monitoring: In asymptomatic cases, regular follow-up may be sufficient to monitor the condition [9][10].

Prognosis
The prognosis for patients with pyeloureteritis cystica varies depending on the severity of the condition and the presence of any complications. With appropriate management, many patients can achieve symptom relief and maintain kidney function.

Pyeloureteritis cystica, classified under the ICD-10-CM code N28.85, is a condition characterized by cystic changes in the renal pelvis and ureter. The diagnosis of this condition typically involves a combination of clinical evaluation, imaging studies, and laboratory tests. Below are the key criteria and methods used for diagnosing pyeloureteritis cystica:

Clinical Evaluation

1. Patient History: A thorough medical history is essential. Patients may present with symptoms such as flank pain, hematuria (blood in urine), or urinary tract infections (UTIs). A history of recurrent UTIs or other urinary tract abnormalities may also be relevant.

2. Physical Examination: A physical examination may reveal tenderness in the flank area, which can indicate underlying renal pathology.

Imaging Studies

1. Ultrasound: A retroperitoneal ultrasound is often the first imaging modality used. It can help visualize cystic lesions in the renal pelvis and ureter, which are characteristic of pyeloureteritis cystica[3][5].

2. CT Scan: A computed tomography (CT) scan of the abdomen and pelvis may be performed for a more detailed assessment. It can provide clearer images of the urinary tract and help differentiate pyeloureteritis cystica from other conditions, such as tumors or stones[3][5].

3. MRI: In some cases, magnetic resonance imaging (MRI) may be utilized, particularly if there is a need to avoid radiation exposure or if the patient has contraindications for CT scans.

Laboratory Tests

1. Urinalysis: A urinalysis can help identify the presence of blood, pus, or bacteria in the urine, which may suggest an infection or inflammation in the urinary tract.

2. Urine Culture: If a UTI is suspected, a urine culture may be performed to identify the causative organism and determine appropriate antibiotic therapy.

3. Blood Tests: Blood tests may be conducted to assess kidney function and check for signs of infection or inflammation, such as elevated white blood cell counts or increased creatinine levels.

Differential Diagnosis

It is crucial to differentiate pyeloureteritis cystica from other conditions that may present similarly, such as:

• Renal tumors: Cystic renal masses can mimic the appearance of pyeloureteritis cystica on imaging studies.
• Ureteral obstruction: Conditions causing obstruction may lead to similar symptoms and imaging findings.
• Other cystic renal diseases: Conditions like polycystic kidney disease should also be considered.
