We describe a case of retrocaval ureter treated with laparoendoscopic single-site surgery (LESS).
A 26-year-old female was referred to our institution with a history of intermittent right-sided flank pain. Radiological imaging demonstrated hydronephrosis, suggesting the presence of a retrocaval ureter. A LESS repair was planned.
Retrograde pyelogram confirmed a classic appearance for retrocaval ureter. A ureteral stent was positioned. The patient was placed in modified flank position. A 2-cm, completely concealed umbilical access was created, through which a single port access platform was positioned. An in-line endoscope was used for visualization. Articulating instruments were used during initial dissection. The entire ureter was mobilized posterior to the vena cava and transected at the caudal-most point where the dilated portion of the proximal ureter ended. The distal ureter was repositioned lateral to the inferior vena cava and spatulated laterally. The proximal ureter was spatulated medially. Two 4-0 Vicryl sutures were used for the ureteroureteral anastomosis. A separate 2-mm grasper placed in the right lower quadrant was used to assist with suture reconstruction. A drain was left through the umbilicus. Blood loss was minimal. Total operative time was 3 hours. The patient was discharged on postoperative day 2. At the 3-month follow-up, diuretic radionuclide scan revealed no evidence of obstruction of the right kidney and the patient was symptom-free.
Albeit challenging, LESS repair for retrocaval ureter is a feasible procedure that can be considered as a treatment option for this rare anatomic anomaly.
我们描述了一例采用经腹腔镜单部位手术(LESS)治疗的逆行性输尿管。
一名 26 岁女性因间歇性右侧腰痛就诊于我院。影像学检查显示肾盂积水,提示存在逆行性输尿管。计划进行 LESS 修复。
逆行肾盂造影证实了逆行性输尿管的典型表现。放置了输尿管支架。患者采用改良侧卧位。在脐部创建了一个 2cm 的完全隐蔽的脐部通道,通过该通道放置了一个单端口通道平台。使用内镜进行可视化。最初的解剖过程中使用了铰接器械。将整个输尿管从腔静脉后方游离,并在近端输尿管扩张部分的最远端截断。将远端输尿管重新定位在腔静脉下方外侧,并向外侧切开。将近端输尿管向内侧切开。使用 2 根 4-0 Vicryl 缝线进行输尿管-输尿管吻合。在右下象限放置一根单独的 2mm 抓钳,以协助缝合重建。在脐部留置引流管。出血量少。总手术时间为 3 小时。患者术后第 2 天出院。在 3 个月的随访中,利尿剂放射性核素扫描显示右肾功能无梗阻证据,患者无症状。
尽管具有挑战性,但逆行性输尿管的 LESS 修复是一种可行的手术方法,可作为这种罕见解剖异常的治疗选择。
