摘要
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。
Objeetive ： To investigate the clinical application and value of MRU in the diagnosis of nonfunctional kidney with transitional cell carcinoma （TCC）of renal pelvic or ureter in post-transplantation of kidney. Methods： MRU were performed for 21 cases clinically confirmed as renal pelvic or ureter transitional cell carcinoma, the imaging findings were checked with post operative findings pathological findings. Some cases performed ureteroscopy ,16 cases by single-incision nephroureterectomy combined with transurethral incision of bladder cuff. Results：TCC were assessed for renal pelvic and ureter in all the 21 patients by MRU finding dilatation of ureter with hydronephrosis. Ureteroscopy were performed for 11 cases had pathological diagnosis, total nephroureterectomy combined with transurethral excision of the bladder cuff has been carried out for 16 cases all have succeed. Conclusions：MRU has a great value in diagnosing renal pelvis and ureter urothelial tumors of post-transplantation when the kidneys are nonvisualized or poorly visualized in IVU. It can provide diagnostic evidence and is helpful with choice of the therapeutic strategy.
