pyeloureteritis cystica

Pyeloureteritis cystica, also known as ureteritis cystica or pyelo-ureteritis cystica, is a rare and benign condition that affects the upper urinary tract, specifically the renal pelvis and ureters.

Characteristics:

• Pyeloureteritis cystica is characterized by the presence of small subepithelial cysts in the walls of the ureters and renal pelvis [1].
• These cysts elevate the mucous membrane of the affected areas, creating round radiolucent areas on urographic studies [2].
• The condition is usually asymptomatic, but it can be diagnosed accidentally during imaging of the upper urinary tract for different reasons [3].

Pathology:

• Pyeloureteritis cystica consists of small suburothelial cysts that raise the mucosa layer of the urothelium [4].
• The exact etiology of this condition is unknown, and there is no specific treatment available [5].

Pyeloureteritis cystica, also known as ureteritis cystica, is a rare condition characterized by the formation of small cysts in the renal pelvis and ureters. While it can be asymptomatic, some people may experience various symptoms.

Possible Symptoms:

• Hematuria (blood in urine) [2, 5]
• Urinary obstruction with flank pain [2, 5]
• Urinary tract infection [5]
• Nephrolithiasis (kidney stones) [3, 5]
• Flank pain or suprapubic pain [4, 7]

Other Possible Presentations:

• Cystitis-like symptoms, such as dysuria (painful urination), frequency, and urgency [4]
• Elevated white blood cell count indicating infection [5]

It's essential to note that pyeloureteritis cystica is often diagnosed incidentally during imaging of the upper urinary tract for other reasons. The condition can be unilateral or bilateral, with most cases being asymptomatic.

Age and Gender:

The average age of patients with pyeloureteritis cystica is around 59 years (range 30 to 77), with a slight predominance in females [6].

Keep in mind that these symptoms may not be specific to pyeloureteritis cystica, and further evaluation by a healthcare professional is necessary for an accurate diagnosis.

Pyeloureteritis cystica, also known as ureteral cystic disease or ureteritis cystica, can be diagnosed through various diagnostic tests.

• Intravenous Urography (IVU): This is a common radiologic test used to diagnose pyeloureteritis cystica. It involves injecting a contrast agent into the bloodstream, which is then excreted by the kidneys and ureters, allowing for visualization of the urinary tract. The appearance on IVU is typically that of multiple small 2-5 mm smooth filling defects in the ureters [3].
• Retrograde Pyelogram: This test involves injecting a contrast agent directly into the renal pelvis through a catheter inserted through the bladder. It can provide detailed images of the ureters and renal pelvis, and is often used to confirm the diagnosis of pyeloureteritis cystica [4], [7].
• Computed Tomography (CT) Urography: CT urography is a non-invasive imaging test that uses X-rays and contrast agent to visualize the urinary tract. It can provide detailed images of the ureters, renal pelvis, and kidneys, and is often used in conjunction with IVU or retrograde pyelogram [9].
• Cystoscopy: This is a minimally invasive procedure where a flexible tube with a camera (cystoscope) is inserted through the bladder to visualize the inside of the ureters. It can be used to diagnose pyeloureteritis cystica, especially when other tests are inconclusive [5].

It's worth noting that diagnosis is often made on the basis of radiologic findings, and biopsy is not usually recommended due to the minor entity of the pathology [2], [6].

Pyeloureteritis cystica, also known as ureteritis cystica, is a rare benign condition characterized by the formation of small subepithelial cysts in the renal pelvis and ureter. While there is no specific treatment for this condition, various treatments have been reported to be effective in managing its symptoms.

No specific treatment required According to search result [5], usually no treatment is required for ureteritis cystica per se, but rather the underlying cause of chronic infection may need treatment, e.g. nephrolithiasis. This suggests that the primary focus should be on addressing any underlying infections or conditions that may be contributing to the development of pyeloureteritis cystica.

Treatment with antibiotics In some cases, treatment with antibiotics has been reported to be effective in managing pyeloureteritis cystica. For example, search result [8] mentions a patient who received empiric treatment

Pyeloureteritis cystica, also known as ureteritis cystica, is a benign condition of the ureters characterized by multiple small submucosal cysts.

Key differential diagnoses to consider:

• Multifocal urothelial tumors or metastases [2]
• Transitional cell carcinoma (TCC) [1]
• Vascular indentations
• Multiple ureteral stones
• Blood clots

These conditions can present with similar radiological findings, making pyeloureteritis cystica a differential diagnosis to consider in cases of atypical imaging results [7].

Other relevant information:

• Pyeloureteritis cystica is typically asymptomatic and does not require active treatment [8].
• The condition can persist unchanged for years despite antibiotic treatment [9].
• Diagnosis is made based on radiologic findings, mainly intravenous urography, with biopsy not recommended due to the minor entity of the pathology [4].
