妇科腹腔镜手术中输尿管损伤的临床特点及处理

目的探讨妇科腹腔镜手术中输尿管损伤的主要原因及诊断、治疗和预防的方法。方法回顾性分析我院13年间,妇科腹腔镜手术中发生输尿管损伤患者的临床资料、疾病类型、盆腔情况、手术类型、损伤特点、诊治情况及预后。结果．5541例妇科腹腔镜手术中,共发生输尿管损伤8例,发生率为0．14％,其中腹腔镜辅助阴式子宫切除术(LAVH)发生输尿管损伤6例,腹腔镜下全子宫切除术(TLH)1例,盆腔侧壁粘连松解手术1例。主要妇科疾病为：子宫腺肌症、子宫内膜异位症、子宫肌瘤;8例均有盆腔粘连,4例有盆腹腔手术史,7例子宫手术者,子宫均有增大(6～10周)。输卵管损伤症状出现于术后0～13d,包括：引流量增多、腹痛或腹胀、腰疼、恶心呕吐、发热、尿量减少、阴道流水、腹部皮下水肿、腹膜炎等。诊断时间在术后0～17d,主要确诊方法为静脉肾盂造影。损伤位于输尿管下段6例,入盆腔段2例。2例早期发现者均行开腹手术修补,晚期发现者,2例输尿管置管成功,3例置管当时失败,1例置管后又出现尿瘘行开腹修补。预后均较好。结论输尿管损伤是妇科腹腔镜手术少见而严重的并发症。术后引流量的异常增多以及出现发热、腰腹痛、急腹症、阴道流水等症状时,应警惕输尿管损伤的可能。治疗以手术为主。

Ureteral injury in gynecologic laparoscopies

Objective To investigate the ureteral injury in gynecological laparoscopies and discuss its diagnosis, treatment and prevention. Methods Ureteral injury in gynecological laparoscopies during the past 13 years was reviewed retrospectively. The clinical features of initial operations including the types ofdisease, uterine size, pelvic adhesion, operative procedures and the methods of diagnosis, treatment and prognosis of ureteral injury were studied. Results There were 8 ureteral injuries (0. 14% ) in 5 541 gynecological laparoscopies with seven in laparoscopically assisted vaginal hysterectomy (LAVH)/ total laparoscopic hysterectomy (TLH) (0.45%) and one in non-LAVH (0.03%). The main gynecological disorders included adenomyosis, endometriosis and leiomyoma. All patients had pelvic adhesions and 4 had previous pelvic operations. Uterine enlargement was found in 7. Patients presented increased vaginal drainage, flank pain, increased volumes of vaginal discharge, nausea and vomiting, fever, edema, or peritonitis from 0 to 13 days postoperatively. Ureteral injuries were mainly diagnosed via excretory urogram (IVP). The sites of injury were near the inferior margin of the sacroiliac joint in two women and at the inferior part of ureter ( near the uterine vessel, uterosacral ligament and ureterovesical junction ) in 6. Two patients whose injuries were found soon after operation received ureteral repair by laparotomy successfully. Two of the six patients whose injuries were found several days later were treated with internal ureteral stenting successfully, the other four failed with ureteral stenting and received ureteral repair by laparotomy. Outcomes were good in all cases. Conclusions Ureteral injury is an uncommon and severe complication in gynecological laparoscopies. Symptoms like abnormally increased drainage, fever, flank pain, abnormal vaginal discharge and peritonitis after operation should be paid attention to and ureteral injury be considered. Surgical repair is the primary treatment
