Calculi from 45 Moroccan children aged between 2 and 15 years underwent morphological and infrared spectrometric analysis. The stones were three times more frequent in males than females (M/F = 3.09). Whewellite was the main component in 51.1% of cases and in 44.4% of stone nuclei, wheddellite in 8.9% of stones and nuclei, carbapatite in 6.7% of stones and 8.9% of nuclei, struvite in 15.6% of stones and 11.1% of nuclei. Ammonium hydrogen urate and uric acid were predominant respectively in 8.9% and 6.7% of stones and in 15.6% and 11.1% of nuclei. In addition to whewellite, struvite and ammonium hydrogen urate were the main components of bladder stones from both sexes. With respect to their calculi, whewellite was present in 84.4% of cases and wheddellite in 26.7%. Purines were present in 46% of calculi, especially as ammonium urate (28.9%) and uric acid (15.6%). Calcium phosphates as the main components were infrequent. In contrast, they were frequently identified in urinary calculi from children, respectively 64.4% and 40% for carbapatite and amorphous carbonated calcium phosphate.
对45名年龄在2至15岁之间的摩洛哥儿童的结石进行了形态学和红外光谱分析。结石在男性中的出现频率是女性的三倍（男/女 = 3.09）。水草酸钙是51.1%的病例和44.4%的结石核心中的主要成分，水合草酸镁在8.9%的结石和结石核心中出现，碳酸磷灰石在6.7%的结石和8.9%的结石核心中出现，磷酸铵镁在15.6%的结石和11.1%的结石核心中出现。尿酸氢铵和尿酸分别在8.9%和6.7%的结石以及15.6%和11.1%的结石核心中占主导地位。除水草酸钙外，磷酸铵镁和尿酸氢铵是两性膀胱结石的主要成分。就其结石而言，84.4%的病例中存在水草酸钙，26.7%的病例中存在水合草酸镁。46%的结石中存在嘌呤，尤其是尿酸铵（28.9%）和尿酸（15.6%）。以磷酸钙为主要成分的情况并不常见。相比之下，它们在儿童尿路结石中经常被鉴定出来，碳酸磷灰石和无定形碳酸磷酸钙分别为64.4%和40%。
