Retrocaval ureter (RCU), also known as circumcaval ureter, occurs due to anomalous development of inferior vena cava (IVC) and not ureter. The surgical approach for this entity has shifted from open to laparoscopic and robotic surgery. This is a relatively new line of management with very few case reports. Herein, we describe the etiopathology, our experience with six cases of transperitoneal laparoscopic repair of RCU operated at tertiary care center in India and have reviewed different management options.
From 2013 to 2016, we operated total six cases of transperitoneal laparoscopic repair of RCU. All were male patients with average age of 29.6 years (14-50). Pain was their only complaint with normal renal function and no complications. After diagnosis with CT Urography, they underwent radionuclide scan and were operated on. Postoperative follow-up was done with ultrasonography every 3 months and repeat radionuclide scan at 6 months. The maximum follow-up was for 2.5 years.
All cases were completed laparoscopically. Average operating time was 163.2 min. Blood loss varied from 50 to 100 cc. Ureteroureterostomy was done in all patients. None developed urinary leak or recurrent obstruction postoperatively. Maximum time for the requirement of external drainage was for 4 days (2-4 days). Average postoperative time for hospitalization was 3.8 days. Follow-up ultrasound and renal scan showed unobstructed drainage.
Transperitoneal or retroperitoneal approach can be considered equivalent as parameters like operative time, results are comparable for these two modalities. We preferred transperitoneal approach as it provides good working space for intracorporeal suturing.
腔静脉后输尿管(RCU),又称环腔静脉输尿管,是由于下腔静脉(IVC)而非输尿管的异常发育所致。该疾病的手术方式已从开放手术转变为腹腔镜手术和机器人手术。这是一种相对较新的治疗方法,病例报告很少。在此,我们描述其病因病理学,分享我们在印度一家三级医疗中心对6例经腹腹腔镜修复RCU的经验,并回顾了不同的治疗选择。
2013年至2016年,我们共对6例RCU患者进行了经腹腹腔镜修复手术。所有患者均为男性,平均年龄29.6岁(14 - 50岁)。他们唯一的症状是疼痛,肾功能正常,无并发症。经CT尿路造影诊断后,他们接受了放射性核素扫描并进行了手术。术后每3个月进行超声检查随访,6个月时重复进行放射性核素扫描。最长随访时间为2.5年。
所有病例均通过腹腔镜完成。平均手术时间为163.2分钟。出血量在50至100毫升之间。所有患者均进行了输尿管输尿管吻合术。术后无一例发生尿漏或复发性梗阻。最长的外引流时间为4天(2 - 4天)。术后平均住院时间为3.8天。随访超声和肾脏扫描显示引流通畅。
经腹或经腹膜后途径可被视为等效方法,因为手术时间等参数表明这两种方式的结果具有可比性。我们更倾向于经腹途径,因为它为体内缝合提供了良好的操作空间。
