Abstract：
UNASSIGNED: The basilic vein transposition is a brachio basilic arteriovenous fistula (AVF) made after the mobilization and transferring of basilic vein to the ventral aspect of arm inside a subcutaneous pocket by direct dissection. The procedure can be performed either in single stage or two stages. This study compares the clinical efficacy and long term utility of single-stage and two-stage basilic vein transposition among patients of renal failure and to evaluate failure rate, primary patency rates, and postoperative complications.
UNASSIGNED: Patients who underwent basilic vein transposition at Sindh Institute of Urology and Transplantation, Karachi from January 2021 to December 2021 were retrospectively reviewed. Patients were divided into two groups according to single stage or two-stage procedure. After the surgical procedure, assessment of fistula maturation and surveillance were undertaken using ultrasound and physical examination. Patients were requested to visit the out-patient clinic for assessment of fistula patency and post-operative complications at regular intervals of 3, 6, and 12 months respectively.
UNASSIGNED: During the 12 months\' interval, 82 (39.04%) basilic vein transpositions were performed in single-stage and 128 (60.95%) were two-staged transposition. In our analysis we have found that as compared to single stage, two-stage basilic vein transpositions showed significantly better primary patency rates (76.82% vs 96%; p-value 0.000) and required less interventions for maintaining fistula patency. More post-operative sequelae were noted in the single stage version of the procedure as compared to the two stage procedure.
UNASSIGNED: Two stage procedure of basilic vein transposition is found to have better patency rate and lesser post-surgical complications. However, a matched cohort prospective study is still needed to further strengthen the conclusion.

摘要：
■贵重静脉转位是在通过直接解剖将贵重静脉动员并转移到皮下口袋内的手臂腹侧后制成的腕臂贵重动静脉瘘（AVF）。该过程可以在单个阶段或两个阶段中执行。这项研究比较了肾衰竭患者单期和两期贵要静脉转位的临床疗效和长期效用，并评估了失败率。主要通畅率，术后并发症。
■在信德省泌尿外科和移植研究所接受贵重静脉转位的患者，对2021年1月至2021年12月的卡拉奇进行了回顾性审查。根据单阶段或两阶段程序将患者分为两组。手术后,使用超声和体格检查对瘘管成熟进行评估和监测.要求患者分别以3、6和12个月的时间间隔访问门诊，以评估瘘管通畅性和术后并发症。
■在12个月的间隔内，单阶段进行82例（39.04%）贵重静脉转位，两阶段转位128例（60.95%）。在我们的分析中，我们发现与单阶段相比，两阶段贵要静脉转位显示出显著较好的原发性通畅率(76.82%vs96%;p值0.000),并且需要较少的干预措施来维持瘘管通畅.与两阶段程序相比，在单阶段程序中发现了更多的术后后遗症。
■两个阶段的贵要静脉转位术被发现具有更好的通畅率和较少的术后并发症。然而,仍需要一项匹配的队列前瞻性研究来进一步强化这一结论.
