目的
2
探讨儿童肾盂输尿管连接部梗阻(UPJO)合并同侧输尿管膀胱连接部梗阻(UVJO)的临床特征、诊断难点及治疗策略。
方法
2
回顾性分析我院2014年1月至2024年12月收治的UPJO合并同侧UVJO患儿的临床资料,包括性别、年龄、首诊诊断、侧别、影像学检查、手术方式及随访结局。
结果
2
首诊为UPJO者9例,UVJO者5例。术前仅MRU提示输尿管扩张者6例,其余均未明确诊断。确诊方式:术中逆行肾盂造影(RPG)5例,术后经肾造瘘管顺行造影(APG)7例,两者联合2例。首次手术:肾盂成形术9例,输尿管膀胱再植术2例,经皮肾穿刺造瘘术2例,输尿管口扩张术1例。10例术中留置肾造瘘管。中位随访5.5年,4例接受二次手术。其中仅1例因持续梗阻需分期处理双重梗阻,另3例初诊UVJO者行再植术后UPJ梗阻自行缓解。10例未二次手术者中,8例术后APG虽提示远端排空延迟,但夹管后无临床症状且肾积水持续改善。
结论
2
儿童UPJO合并同侧UVJO术前诊断困难,术中顺行或逆行留置输尿管支架管失败时需进一步评估。首诊UVJO者首选肾盂成形术,无需常规逆行肾盂造影,但留置肾造瘘管术后APG评估可避免不必要的输尿管再植。初诊UVJO且输尿管严重扩张者,可先行输尿管再植。
Objective
2
To investigate the clinical characteristics, diagnostic challenges, and treatment strategies in pediatric patients with ureteropelvic junction obstruction (UPJO) complicated with ipsilateral ureterovesical junction obstruction (UVJO).
Methods
2
A retrospective analysis was conducted on clinical data of pediatric patients admitted to our hospital between January 2014 and December 2024 with a confirmed diagnosis of UPJO complicated with UVJO. The collected clinical parameters included gender, age at presentation, initial diagnosis, lesion laterality, imaging findings, surgical procedures, and follow-up outcomes.
Results
2
The study cohort comprised 14 pediatric patients (male=10 and female=4) with a median age of 3.1 months at presentation. The initial diagnoses were UPJO in 9 cases and UVJO in 5 cases. Preoperatively, only 6 cased showed ureteral dilation on MRU. The definitive diagnosis was confirmed by intraoperative retrograde pyelography in 5 cases, postoperative antegrade pyelography via a nephrostomy tube in 7 patients, and combined application of the two modalities in 2 patients. For primary surgical intervention, 9 patients underwent pyelo-plasty, 2 underwent ureteral reimplantation, 2 received percutaneous nephrostomy, and 1 underwent ureteral orifice dilation. Intraoperative nephrostomy tube placement was performed in 10 patients. With a median follow-up duration of 5.5 years, 4 patients required revision surgery. Of these, only 1 patient , who had an initial diagnosis of UPJO, required staged management for persistent obstruction, whereas UPJ obstruction resolved after ureteroneocystostomy in the remaining 3 patients with an initial diagnosis of UVJO. Among the 10 patients who did not undergo revision surgery, 8 showed delayed distal urinary drainage on APG, yet remained asymptomatic with continuous improvement of hydronephrosis after nephrostomy tube clamping.
Conclusions
2
Preoperative diagnosis of concurrent UPJO and ipsilateral UVJO in pediatric patients is clinically challenging. Further intraoperative evaluation is mandatory when antegrade or retrograde ureteral stent placement fails during surgery. For patients with an initial diagnosis of UPJO, pyeloplasty is the first-line treatment. Routine retrograde pyelography is not recommended, whereas nephrostomy tube with subsequent postoperative APG evaluation can prevent unnecessary ureteroneocystostomy. For patients with an initial diagnosis of UVJO accompanied by severe ureteral dilation, primary ureteroneocystostomy is feasible initial management strategy.
