We report 8 patients with urolithiasis in a duplex system. These patients (7 males and 1 female) underwent 16 extracorporeal shock wave lithotripsy (ESWL) treatments. Five had renal and 3 had ureteral stones. The mean stone size was 21 mm (12-54 mm). Five patients had incomplete and 3 had complete duplication, of which one had an associated horseshoe kidney. Retrograde ureteropyelography was done in all the patients and in 7 a JJ stent was inserted. The JJ stent could not be inserted in 1 patient with incomplete duplication and retrograde catheterization with saline infusion was used as an auxiliary procedure. One patient with complete duplication had stones in both the ipsilateral ureters with a stone bulk of 54 mm and required two JJ stents. Only 1 paediatric patient required general anaesthesia. The 3-month stone-free rate was 100%.
我们报告了8例双肾盂系统尿路结石患者。这些患者（7名男性和1名女性）接受了16次体外冲击波碎石术（ESWL）治疗。5例为肾结石，3例为输尿管结石。结石平均大小为21毫米（12 - 54毫米）。5例患者为不完全性双肾盂，3例为完全性双肾盂，其中1例合并马蹄肾。所有患者均行逆行输尿管肾盂造影，7例患者置入了双J支架。1例不完全性双肾盂患者无法置入双J支架，采用盐水灌注逆行插管作为辅助操作。1例完全性双肾盂患者双侧输尿管均有结石，结石体积为54毫米，需要置入两个双J支架。仅1例儿科患者需要全身麻醉。3个月无石率为100%。
