小的非梗阻肾盏结石一般无症状,不需要外科处理。但当小的肾盏结石伴有腰部或肋脊角疼痛时多数泌尿科专家认为疼痛和结石无关。作者在1985～1986年间应用体外震波碎石(ESWL)治疗446例患者,并对其中22例伴有腰痛或肋脊角疼痛但无梗阻的小的肾盏结石进行了研究,男性9例,女性13例,年龄23～68岁。治疗前疼痛的平均时间为18个月(1～6年),术前行静脉肾盏造影(IVP)检查,结石大小为2～10mm。平均为5.5mm,无梗阻表现。碎石震波冲击次数为375—2175,碎石电压为18KV。术后第1和第14天均做肾、输尿管和膀胱的X线照片及超声检查以便了解结石碎片
Small non-obstructive calyx stones are asymptomatic and do not require surgical treatment. However, when a small calyx calculus with lumbar or rib ridge pain most Urologists believe that pain and stones have nothing to do. The authors used 446 patients treated with extracorporeal shock wave lithotripsy (ESWL) between 1985 and 1986 and studied 22 cases of small calyceal calculus with pain in lumbar or rib ridge pain without obstruction. There were 9 males 13 cases, aged 23 to 68 years. The average duration of pain before treatment was 18 months (range 1 to 6 years). Preoperative intravenous calorimetry (IVP) was used and the stone size was 2 to 10 mm. Average 5.5mm, no obstruction performance. Shock shock shock frequency is 375-2175, gravel voltage is 18KV. Renal, ureteric, and urinary bladder radiographs and ultrasonography were performed on the first and the fourteenth days to understand the stone fragments
