目的 :探讨诊治肾盂输尿管连接部 (UPJ)梗阻的新方法。方法 :先天性 UPJ梗阻患者 47例 ,术前诊断主要依靠电视下逆行肾盂造影和利尿性 B超检查。外科治疗主要采用自行设计的双叶舌状肾盂壁瓣肾盂成形术。结果 :B超和电视下逆行肾盂造影对 UPJ梗阻的确诊率分别为80 .2 %和 1 0 0 %。双叶舌状肾盂壁瓣肾盂成形术后吻合口更通畅 ,无狭窄或漏尿并发症。结论 :在UPJ梗阻的术前诊断中 ,电视下逆行肾盂造影明显优于 IVU。 B超检查仍不失为一种很好的方法。双叶舌状肾盂壁瓣肾盂成形术疗效满意。
Objective: To explore a new method of diagnosis and treatment of ureteropelvic junction obstruction. Methods: 47 cases of congenital UPJ obstruction, preoperative diagnosis mainly rely on retrograde pyelonephography and diuretic B-ultrasound. Surgical treatment of the main use of their own design of double-leaf tongue pyelic pyeloplasty. Results: The diagnostic rates of retrograde pyelography under UP and TV on UPJ obstruction were 80.2% and 100% respectively. Double lenticular pelvic wall flap after pyeloplasty anastomotic more smooth, no stenosis or leakage of urine complications. Conclusion: In the preoperative diagnosis of UPJ obstruction, retrograde pyelography under TV is superior to IVU. B-ultrasound is still a good way. Two-leaf tongue pyeloplasty with pyeloplasty was satisfactory.
