To determine the incidence of pollakiuria in children with idiopathic hypercalciuria.
The clinical records of 56 children with idiopathic hypercalciuria were reviewed. In addition to pollakiuria, they were evaluated for other associated disorders, maximum urinary osmolality, urodynamic study and overall clinical course.
Nine children (16%), 4 boys and 5 girls, presented with pollakiuria associated with urgency, nocturnal enuresis, hematuria and urinary incontinence. Two showed normal urodynamic studies and unstable bladder was observed in another case. All but one patient preserved normal renal concentration capacity. The course of the micturition symptoms was satisfactory and only three cases required pharmacological treatment.
In the absence of urinary infection, pollakiuria might suggest the presence of hypercalciuria, a condition that can be managed successfully following correct diagnosis and treatment. Renal concentration capacity is not reduced by hypercalciuria.
确定特发性高钙尿症患儿尿频的发生率。
回顾了56例特发性高钙尿症患儿的临床记录。除尿频外，还对他们进行了其他相关疾病、最大尿渗透压、尿动力学研究及整体临床病程的评估。
9名儿童（16%），4名男孩和5名女孩，表现出与尿急、夜间遗尿、血尿和尿失禁相关的尿频。2例尿动力学研究正常，另1例观察到膀胱不稳定。除1例患者外，所有患者的肾脏浓缩功能均正常。排尿症状的病程令人满意，仅3例需要药物治疗。
在无泌尿系统感染的情况下，尿频可能提示存在高钙尿症，这种情况在正确诊断和治疗后可成功处理。高钙尿症不会降低肾脏浓缩功能。
