ICD-10: N28.84

Clinical Description of Pyelitis Cystica (ICD-10 Code N28.84)

Definition and Overview
Pyelitis cystica, classified under ICD-10 code N28.84, refers to a specific type of inflammation of the renal pelvis characterized by the presence of cysts. This condition is often associated with chronic urinary tract infections and can lead to significant renal complications if not addressed promptly. The term "pyelitis" denotes inflammation of the renal pelvis, while "cystica" indicates the formation of cysts within this area.

Etiology
The primary cause of pyelitis cystica is typically linked to chronic irritation or infection of the urinary tract. Factors contributing to this condition may include:

• Chronic Urinary Tract Infections (UTIs): Persistent infections can lead to inflammation and cyst formation in the renal pelvis.
• Obstruction: Conditions that obstruct urine flow, such as kidney stones or anatomical abnormalities, can predispose individuals to pyelitis cystica.
• Reflux Nephropathy: This condition, where urine flows backward from the bladder into the kidneys, can also contribute to the development of pyelitis cystica.

Clinical Presentation
Patients with pyelitis cystica may present with a variety of symptoms, including:

• Flank Pain: Discomfort or pain in the side or back, often associated with kidney inflammation.
• Dysuria: Painful urination, which may occur due to associated urinary tract infections.
• Fever and Chills: Systemic symptoms may arise if there is a significant infection.
• Hematuria: Blood in the urine can occur, indicating irritation or damage to the urinary tract.

Diagnosis
Diagnosis of pyelitis cystica typically involves a combination of clinical evaluation and imaging studies. Key diagnostic methods include:

• Urinalysis: To detect signs of infection, such as white blood cells, bacteria, or blood.
• Imaging Studies: Ultrasound or CT scans may be utilized to visualize the kidneys and identify cysts or other abnormalities in the renal pelvis.

Management and Treatment
The management of pyelitis cystica focuses on addressing the underlying causes and alleviating symptoms. Treatment options may include:

• Antibiotic Therapy: To treat any underlying urinary tract infections.
• Surgical Intervention: In cases where obstruction is present, procedures may be necessary to relieve the blockage.
• Supportive Care: Pain management and hydration are essential components of treatment.

Prognosis
The prognosis for individuals with pyelitis cystica largely depends on the underlying cause and the timeliness of treatment. Early intervention can lead to favorable outcomes, while untreated cases may result in complications such as chronic kidney disease or recurrent infections.

Conclusion

Pyelitis cystica, represented by ICD-10 code N28.84, is a significant renal condition that requires careful diagnosis and management. Understanding its etiology, clinical presentation, and treatment options is crucial for healthcare providers to ensure effective patient care and prevent potential complications associated with this condition.

Clinical Presentation of Pyelitis Cystica (ICD-10 Code N28.84)

Pyelitis cystica, classified under ICD-10 code N28.84, is a rare condition characterized by the presence of cysts in the renal pelvis, often associated with chronic urinary tract infections (UTIs). Understanding its clinical presentation, signs, symptoms, and patient characteristics is crucial for accurate diagnosis and management.

Signs and Symptoms

1. Flank Pain: Patients may experience unilateral or bilateral flank pain, which can vary in intensity. This pain is often a result of inflammation or pressure from cysts in the renal pelvis[1].
