From November, 1987 to December, 1990, 399 cases of ureteral calculi were treated by rigid ureteroscopy (URS). Our success and complication rates are presented. Of these, 99 (25%) had a calculus in the pelvis (78/99), iliac (15/99) or lumbar (6/99) ureter, and 300 (75%) had Sandstrasse in the distal ureter. The cases with Sandstrasse were submitted to ureteroscopy within the first 48-72 hours to remove the ureteral obstruction, prevent hydronephrosis or sepsis and to expedite treatment. If symptomatic, obstructive and/or 7 mm or more in diameter, a nephrostomy tube was placed first whenever there was sepsis [23/300 (7%) of those with Sandstrasse and 3/99 (3%) of those with a ureteral calculus] or marked dilatation of the renal cavities [29/300 (9%) and 6/99 (6%), respectively]. The success rate was 93% for the cases with Sandstrasse versus 85% for those with a ureteral calculus, and the complication rates were 5.7% versus 9%, respectively. The foregoing results confirm the high success rate and scant morbidity of ureteroscopy in the treatment of ureteral calculus and Sandstrasse.
1987年11月至1990年12月，399例输尿管结石患者接受了硬性输尿管镜检查（URS）。现将我们的成功率和并发症发生率报告如下。其中，99例（25%）结石位于肾盂（78/99）、髂部（15/99）或腰部（6/99）输尿管，300例（75%）远端输尿管存在铸型结石。铸型结石患者在最初48 - 72小时内接受输尿管镜检查，以解除输尿管梗阻、预防肾积水或脓毒症并加快治疗。如有症状、存在梗阻和/或直径7mm及以上，若存在脓毒症（铸型结石患者中23/300（7%），输尿管结石患者中3/99（3%））或肾腔明显扩张（分别为29/300（9%）和6/99（6%）），则先行放置肾造瘘管。铸型结石患者的成功率为93%，输尿管结石患者为85%，并发症发生率分别为5.7%和9%。上述结果证实输尿管镜检查在治疗输尿管结石和铸型结石方面成功率高且发病率低。
