离断式肾盂成形术治疗肾盂输尿管连接部梗阻的疗效观察

Clinical Study on Treatment of Ureteropelvic Junction Obstruction with Dismembered Pyeloplasty

目的总结肾盂输尿管连接部梗阻（UPJO）的诊治体会。方法分析36例肾盂输尿管连接部梗阻患者的临床资料。其中肾盂输尿管连接部狭窄21例,肾盂输尿管高位连接8例,迷走血管压迫4例,纤维索压迫3例。采用离断式肾盂成形术,术中置双J管引流。结果术后随访12~64个月,平均36个月,分别行B超I、VP检查,有32例（88.9%）肾积水消失或明显减轻,3例（8.3%）无明显变化,1例（2.8%）积水加重。结论离断式肾盂成形术治疗肾盂输尿管连接部梗阻疗效显著。

Objective To summarize the experience on diagnosis and treatment of ureteropelvic junction obstruction（UPJO） with dismembered pyeloplasty.Methods The clinical data of 36 patients with UPJO were retrospectively analyzed.Within these 36 patients,there were 21 patients with ureteropelvic junction obstruction,8 patients with high ureteropelvic junction obstruction,4 patients with compression from crossing blood vessels,and 3 patients with compression from fiber cables.All the patients underwent dismembered pyeloplasty.Results All the patients were examined with B-ultrasonography and IVP and followed up from 12 to 64 months,with the average follow-up survey time of 36 months.Hydronephrosis completely disappeared or significantly subsided in 32（88.9%） patients.3（8.3%） patients with hydronephrosis had no significant change,and 1（2.8%） patient with hydronephrosis became more serious than before.Conclusions Dismembered pyeloplasty is a good choice for the patients with ureteropelvic junction obstruction.
