目的：探讨磁共振水成像(Magnetic resistance urography,MRU)在肾移植术后对原自体无功能性肾、输尿管移行细胞癌的诊断价值。方法：对21例肾移植术后临床诊断为肾盂或输尿管移行细胞癌患者进行MRU检查,同时行逆行肾盂输尿管造影；11例行输尿管镜及病理学检查,并行MRU诊断。16例行经尿道输尿管口环形切开、腰部一处切口的肾输尿管全长切除术。结果：术前21例MRU检查均提示肾盂、输尿管有占位性病变,11例配合输尿管镜得出组织学诊断,术前诊断与手术结果一致。21例中,16例采用肾输尿管全长切除术均获得成功。结论：MRU对肾移植术后IVU不显影的原无功能性肾、输尿管移行细胞癌具有重要的临床诊断价值；输尿管口切除、肾输尿管全长切除术对移植肾同侧原肾发生肾盂输尿管癌一样有效。
Objective: To investigate the value of magnetic resonance urography (MRU) in the diagnosis of autologous non-functional kidney and ureter transitional cell carcinoma after renal transplantation. Methods: Twenty-one patients with renal pelvic or ureteric transitional cell carcinoma who underwent renal transplantation were retrospectively retrospectively examined by MRU and ureteroscopy and pathology. MRU was performed in 11 patients. 16 cases of transurethral ureteral orifice ring incision, lumbar incision of the total length of renal ureter resection. Results: Twenty-one patients underwent MRU before operation, which indicated that the renal pelvis and ureter had space-occupying lesions. Histological diagnosis was obtained in 11 patients with ureteroscopy. The preoperative diagnosis was consistent with the surgical findings. Among 21 cases, 16 cases were successfully treated with total nephroureterectomy. Conclusion: MRU has important clinical diagnostic value for non-functional renal and ureteric transitional cell carcinoma of IVU after renal transplantation, ureteropectomy and total ureterrectomy for renal pelvis and ureter in renal transplantation As effective.
