Summary
Pyeloureteritis cystica, a rare condition, was diagnosed in a 70-year-old female presenting with microhematuria. Ureteroscopic examination and biopsy confirmed chronic ureteritis, with a review of 44 Japanese cases.
Area of Science:
- Urology
- Pathology
Background:
- Pyeloureteritis cystica is a rare inflammatory condition affecting the renal pelvis and ureters.
- Diagnosis often involves imaging and histological examination.
Observation:
- A 70-year-old female presented with microhematuria, a key symptom.
- Imaging studies revealed multiple filling defects in the bilateral renal pelvis and ureters.
- Urinary cytology indicated class III findings on both sides.
Findings:
- Ureteroscopic examination and cold cup biopsy were performed.
- Histological examination confirmed chronic ureteritis.
- This case, along with 44 previously reported Japanese cases, is reviewed.
Implications:
- This case contributes to understanding the clinical presentation and diagnosis of pyeloureteritis cystica.
- The review of Japanese cases may offer insights into regional prevalence or specific characteristics.
- Accurate diagnosis through ureteroscopy and biopsy is crucial for appropriate management.
