摘　　要：目的:总结改良气膀胱下Politano-Leadbetter术治疗输尿管末端狭窄的经验,提高诊治水平。方法:回顾性分析厦门大学附属妇女儿童医院(厦门市妇幼保健院)小儿外科2020年1月—2022年1月收治的15例输尿管膀胱连接部狭窄患儿的临床资料,患儿均采用改良气膀胱下Politano-Leadbetter术治疗。其中男12例,女3例;年龄6个月~8岁,平均4.5岁;右侧5例,左侧9例,双侧1例。手术方法:建立气膀胱,膀胱内游离输尿管下段,末端输尿管口缝合牵引线,应用尿道口-输尿管开口-新输尿管裂孔三点一线原理,准确寻找膀胱外输尿管。将已游离的输尿管自新输尿管裂孔重新迁入膀胱内,建立黏膜下隧道,将输尿管远端包埋于黏膜下隧道内,缝合输尿管口,再置入双J管,完成Leadbetter输尿管再植手术。术后定期复查尿常规了解尿道感染情况,泌尿系彩超及排泄性膀胱尿道造影(voiding cystourethrography,VCUG)评估肾积水、输尿管扩张或狭窄、是否存在输尿管反流等指标。结果:15例患儿均经气膀胱下完成Politano-Leadbetter术,无一例中转开放手术。手术时间单侧81~103min,平均(91.0±16.5)min;双侧136~165min,平均(149.0±15.4)min。术中几乎无明显出血。留置尿管7~8d,拔除尿管后所有患儿均未出现排尿困难、切口感染或裂开,住院时间8~15d。术后随访12~24个月,近期无尿漏、切口感染、尿路感染,远期无膀胱输尿管反流、膀胱输尿管连接部梗阻等并发症。术后12个月复查彩超测得肾盂前后径为(0.95±0.35)cm,较术前的(2.68±0.75)cm明显减小;输尿管最大直径为(0.75±0.21)cm,也比术前的(2.85±0.65)cm明显减小,差异均有统计学意义(P<0.01)。结论:改良气膀胱下Politano-Leadbetter术已是一种技术成熟且易于学习的手术方法,手术成功率高,术后恢复快,保留了原始输尿管的开口位置与解剖走向,是治疗小儿输尿管末端狭窄类疾病一种安全有效的手术方式。Objective:To summarize the experience of the modified Politano-Leadbetter procedure under the pneumatic bladder for the treatment of distal ureteral stenosis,and improve the level of diagnosis and treatment.Methods:A retrospective analysis was conducted on the clinical data of 15 children with ureterobladder junction stenosis admitted to the pediatric surgery department of Xiamen Maternal and Child Health Hospital from January 2020 to January 2022.All patients were treated with modified pneumatic bladder laparoscopic Politano-Leadbetter procedure including 12 boys and 3 girls;The average age was 4.5 years from 6 months to 8 years old.Among them,there were 5 cases on the right side,9 cases on the left side,and 1 case on both sides.Operation method:establish the pneumatic bladder routinely,place laparoscope and operation instruments under cystoscope,free the ureter in the bladder,and apply the three-point one line principle of urethral orifice ureteral opening new ureteral hole to accurately find the ureter outside the bladder.Free the lower segment of the ureter,suture the traction line at the end of the ureter,relocate the already free ureter into the bladder from the new ureteral hiatus,establish a submucosal tunnel,embed the distal ureter into the submucosal tunnel,remove the narrow and partially dilated ureter,suture the urethral opening,and then insert a double J tube to complete the Leadbetter ureteral reimplantation surgery.Urine routine was regularly reviewed after the operation,and urinary color ultrasound and voiding cystourethrography(VCUG)were examined to evaluate indicators such as hydronephrosis,ureteral dilation or stenosis,presence of ureteral reflux,and renal function parameters.Results:All 15 cases underwent Politano-Leadbetter surgery under the pneumatic bladder without conversion to open surgery.The unilateral surgery time was 81 to 103 minutes,with an average of(91.0±16.5)minutes.The bilateral surgery time ranged from 135 to 165 minutes,with an average of(149.0±15.4)minutes.There was almost
