    Area of Science:

    • Urology
    • Oncology

    Background:

    • Indeterminate pelvic and caliceal filling defects require accurate diagnosis.
    • Transitional cell carcinoma (TCC) is a significant urinary tract malignancy.

    Observation:

    • Intraoperative pyeloscopy was utilized in 18 patients with indeterminate filling defects.
    • These defects were subsequently diagnosed as TCC.

    Findings:

    • Two patients experienced local tumor recurrence in the renal fossa after nephroureterectomy.
    • Intraoperative pyeloscopy is associated with considerable risks.

    Implications:

    • The risk of transitional cell carcinoma seeding during pyeloscopy is a critical concern.
    • This suggests careful consideration of diagnostic and therapeutic strategies for renal filling defects.
