Objective: To investigate the management of crossing vessels compression in laparoscopic pyeloplasty.
Methods: From January 2016 to June 2018, a total of 21 patients who were admitted to Peking University People's Hospital with ureteropelvic junction obstruction (UPJO) associated with crossing vascular compression were reviewed. There were 15 males and 6 females who formed this group, with a mean age of (33.9±15.0) years. There were 4 cases of mild hydronephrosis, 12 cases of moderate hydronephrosis and 5 cases of severe hydronephrosis before operation. All the patients underwent laparoscopic pyeloplasty in our hospital, including 13 on the left and 8 on the right. Laparoscopic pyeloplasty (Anderson-Hynes) were performed in all the patients. Hem-o-lok suspension (14 cases in the suspension group) or translocation of the crossing vessels (7 cases in the translocation group) were used for the intraoperative management of the crossing vessels. Double J tubes were removed 8 weeks postoperatively. The patient demographic data were collected (including operation time, treatment time of crossing vessels, intraoperative blood loss, time of drainage tube removal after operation, and average length of hospital stay), postoperative outcomes were evaluated and the patients were followed up regularly.
Results: In all the patients, the crossing vessels were successfully reserved, and none of them were ligated intra-operatively. Mean operative times were (202.2±57.0) min. The duration of intraoperative treatment of crossing vessels was (10.5±3.2) min, (6.1±2.0) min in the suspension group, and (13.7±5.2) min in the translocation group, respectively. Intraoperative blood loss was (47.8±25.6) mL, postoperative drainage time was (4.8±2.6) d, and length of hospital stay was (11.5±3.3) d. Postoperative slight urinary leakage occurred in 1 case. Preoperative pyelectasis of the affected side of all the patients was (3.4±1.7) cm, compared with postoperative pyelectasis of (1.9±1.3) cm. The difference was statistically significant (P<0.05). Postoperative follow-up of all the patients was carried out until December 2018. There was no significant difference in kidney size in all the patients before or after the operations, and hydronephrosis was alleviated compared with that before surgery.
Conclusion: For UPJO patients with crossing vascular compression, according to the location of the crossing vessels, Hem-o-lok suspension or vessel transposition can be adopted to relieve the crossing vascular compression and improve the success rate of the surgery.
目的: 探讨腹腔镜肾盂成型术中对异位压迫血管的处理方法。
方法: 2016年1月至2018年6月共21例合并异位血管压迫的肾盂输尿管连接部狭窄(ureteropelvic junction obstruction, UPJO)患者在北京大学人民医院行腹腔镜肾盂成型术,其中男性15例、女性6例,平均年龄(33.9±15.0)岁,左侧13例、右侧8例。患者术前轻度肾积水4例、中度12例、重度5例。所有患者均行腹腔镜肾盂离断成型术(Anderson-Hynes术式),术中对于异位血管的处理采用Hem-o-lok悬吊(悬吊组14例)或将异位血管转位(转位组7例)两种方法,术后8周拔除双J管。收集患者临床资料(包括手术时间、异位血管处理时间、术中出血量、术后拔除引流管时间以及平均住院天数),术后对患者定期随访并进行手术效果评价。
结果: 所有患者的异位血管都得到成功保留,无一例在术中离断异位血管。本组平均手术时间(202.2±57.0) min,术中处理异位血管的平均时间(10.5±3.2) min,其中悬吊组为(6.1±2.0) min,转位组为(13.7±5.2) min。术中出血量(47.8±25.6) mL,术后拔除引流管时间(4.8±2.6) d,平均住院天数(11.5±3.3) d。术后发生轻微尿漏1例,所有患者术前患侧肾盂扩张(3.4±1.7) cm,术后3个月患侧肾盂扩张(1.9±1.3) cm,差异有统计学意义(P<0.05)。术后随访至2018年12月,所有患者肾脏大小无明显变化,肾积水均较术前有所缓解。
结论: 对于合并异位血管压迫的UPJO患者,在行肾盂成型术的同时,可以根据异位血管的位置采取Hem-o-lok悬吊或血管转位的方法来解除异位血管压迫,提高手术成功率。
