This case study details bilateral pyeloureteritis cystica, a rare condition found in a 67-year-old woman presenting with asymptomatic macrohematuria. Imaging and biopsy confirmed the diagnosis, with the patient undergoing observation rather than adjuvant therapy.
Area of Science:
- Urology
- Pathology
Background:
- Pyeloureteritis cystica is a rare benign inflammatory condition characterized by submucosal cysts in the renal pelvis and ureters.
- It can present with various urinary symptoms or be asymptomatic, posing diagnostic challenges.
Observation:
- A 67-year-old female presented with asymptomatic macrohematuria.
- Radiological imaging, including drip infusion pyelography and enhanced computed tomography, revealed multiple small, round filling defects in both renal pelvises and ureters.
- Ureteroscopy with cold punch biopsy was performed for definitive diagnosis.
Findings:
- Histological examination confirmed the presence of pyeloureteritis cystica.
- The condition affected both the renal pelvises and ureters bilaterally.
Implications:
- This case highlights the importance of considering rare diagnoses like pyeloureteritis cystica in patients with unexplained urinary findings.
- The successful management through careful follow-up without adjuvant therapy suggests a conservative approach may be appropriate in select cases.
- Further research into the etiology and optimal management of pyeloureteritis cystica is warranted.
