A case of primary carcinoma in situ of the ureter in a 77-year-old man is reported. The patient had been to another hospital with right flank pain and macroscopic hematuria. Ultrasound sonogram showed right hydronephrosis. An excretory urogram showed right hydronephrosis and stenosis of right ureter. He was referred to our hospital for further evaluation and treatment. Retrograde pyelogram demonstrated a right ureteral stricture at the level of S1-2, but no space occupying lesion was detected in the ureter. Cytology of voided urine was negative for malignant cells and no other abnormal findings were present. Probe laparotomy was performed under the preoperative diagnosis of ureteral stricture. During the operation, frozen section examination of the stenotic ureter showed carcinoma in situ and so we performed right total nephroureterectomy with a bladder cuff. Pathologic diagnosis was primary carcinoma in situ of the right ureter. The patient has been doing well for six months postoperatively with no evidence of recurrent or metastatic disease.
报告了一例77岁男性输尿管原位癌病例。该患者因右侧腰痛和肉眼血尿前往另一家医院就诊。超声检查显示右肾积水。排泄性尿路造影显示右肾积水和右侧输尿管狭窄。他被转诊至我院进行进一步评估和治疗。逆行肾盂造影显示在S1-2水平右侧输尿管狭窄，但输尿管内未检测到占位性病变。尿细胞学检查未发现恶性细胞，也无其他异常发现。在术前诊断为输尿管狭窄的情况下进行了探查性剖腹手术。手术过程中，对狭窄的输尿管进行冰冻切片检查显示为原位癌，因此我们进行了右侧全肾输尿管切除术并切除膀胱袖口。病理诊断为右侧输尿管原位癌。患者术后六个月情况良好，无复发或转移疾病的迹象。
