肾盂输尿管连接部梗阻主要为先天性异常所致,常常并发肾积水、肾结石和感染。梗阻系结石形成的最主要的因素,而结石又能促使梗阻、染感加重,三者互为因果。我院从1970～1980年共收治肾盂输尿管连接部梗阻100例,其中手术治疗72例,占同期肾脏手术的12.1%。100例中并发肾结石60例,均有肾积水和染感。本文就肾盂输尿管连接部梗阻与肾结石的关系作一探讨。 Ureteropelvic junction obstruction is mainly caused by congenital anomalies, often complicated by hydronephrosis, kidney stones and infections. Obstruction is the most important factor in the formation of stones, and stones can promote obstruction, increased staining, the three are each causal. Our hospital from 1970 to 1980 were treated 100 cases of ureteropelvic junction obstruction, of which 72 cases of surgical treatment, accounting for 12.1% of the same period of kidney surgery. 100 cases of renal calculi in 60 cases, both hydronephrosis and dye. This article discusses the relationship between renal pelvis and ureteropelvic junction obstruction.
