Precipitation of calcium oxalate was studied in a group of ten patients who underwent transurethral prostatectomy with glycine irrigation. Post operatively all patients showed hyperoxaluria; 60% with oxaluria higher than 10 times the critical concentration of calcium oxalate in urine. Other factors, known to favour crystallogenesis were modified during the same period: low urinary output, relative hypercalciuria and uraturia and hypomagnesuria. Thus, conditions for intraluminal precipitation of calcium oxalate were present post operatively. We suggest the use of a xanthine oxidase inhibitor to prevent hyperoxaluria.
对一组接受经尿道前列腺切除术并使用甘氨酸冲洗的10名患者的草酸钙沉淀情况进行了研究。术后所有患者均出现高草酸尿症；60%的患者草酸尿高于尿中草酸钙临界浓度的10倍。在同一时期，其他已知有利于晶体形成的因素也发生了改变：少尿、相对性高钙尿症、尿酸尿症和低镁尿症。因此，术后存在草酸钙管腔内沉淀的条件。我们建议使用黄嘌呤氧化酶抑制剂来预防高草酸尿症。
