To report the initial experiences with functional cine magnetic resonance urography (cine MRU) and assess its usefulness as a novel postoperative evaluation method of ileal ureter substitution.
The medical records of 17 patients from who underwent cine MRU during June 2010 to December 2019 during their follow-up after ileal ureter substitution were collected. The cine MRU videos of reconstructive urinary tract were observed, and the luminal diameter, contraction ratio, peristaltic waves, and ureteral jets were measured.
Seventeen patients underwent cine MRU after ileal ureter substitution during their follow-up. Based on their cine MRU videos assessing the morphology and the peristaltic motility of the reconstructive urinary tract, there was resolution of preoperative hydronephrosis, which matched their ameliorative renal function. Clearly, peristaltic motility of the ileal graft was observed in 14 patients with obvious peristaltic waves and ureteral jets.
This study is the first to assess the clinical utility of functional cine MRU during the patient follow-up after ileal ureter substitution. Cine MRU is a radiation-free, non-invasive imaging method that can clearly show the morphology and the peristaltic motility of the ileal graft. Therefore, cine MRU, as a novel technique, will be extremely useful in the postoperative evaluation of patients after ileal ureter substitution.
报告功能磁共振尿路成像（cine MRU）的初步经验，并评估其作为回肠代输尿管术后评估的新方法的有用性。
收集了 2010 年 6 月至 2019 年 12 月期间 17 例接受回肠代输尿管术后 cine MRU 随访患者的病历。观察了重建尿路的 cine MRU 视频，并测量了管腔直径、收缩比、蠕动波和输尿管射流。
17 例患者在回肠代输尿管术后随访期间接受了 cine MRU。根据他们的 cine MRU 视频评估重建尿路的形态和蠕动运动，术前的肾盂积水得到缓解，与肾功能改善相匹配。在 14 例患者中，明显可见蠕动波和输尿管射流，观察到回肠移植物的蠕动运动。
这是首例评估回肠代输尿管术后患者随访中功能 cine MRU 的临床应用价值的研究。Cine MRU 是一种无辐射、非侵入性的成像方法，可以清楚地显示回肠移植物的形态和蠕动运动。因此，作为一种新的技术，cine MRU 将在回肠代输尿管术后患者的术后评估中非常有用。
