In a female patient who presented with the complaint of dysuria, angiography was required to distinguish a vascular impression on the renal pelvis from a possible tumor or calculus. Neither intravenous urography nor retrograde pyelogram clarified the smooth filling defect sufficiently to rule out the possibility of a urothelial tumor.
一位女性患者因排尿困难前来就诊，需要进行血管造影以区分肾盂上的血管压迹与可能的肿瘤或结石。静脉肾盂造影和逆行肾盂造影均未充分明确光滑的充盈缺损，以排除尿路上皮肿瘤的可能性。
