The patient was a 20-month-old girl. She visited some pediatric clinic with the chief complaint of voiding difficulty and miction pain from October 5, 1991. Excretory urogram, abdominal ultrasound and computed tomographic scan revealed a retrovesical mass which compressed the urinary bladder antero-superiorly. She was referred to our hospital for further evaluation. Physical examination disclosed a fist-sized tumor in her lower abdomen, which persisted after bladder emptying. Cystoscopy revealed elongation of the urethra and elevation of the bladder base. Tumor markers and endocrine examination were normal. Magnetic resonance imaging at 2 weeks after admission revealed that the retrovesical tumor had been translocated cranial to the bladder. Operation was done on October 29, 1991. The tumor originated from the right ovary and was 6.2 x 5.0 x 5.0cm in size and 60g in weight. The cut surface of the surgical specimen included the fatty tissue and hair, and the pathological diagnosis was an ovarian dermoid cyst. This is the youngest case of ovarian dermoid cyst presenting as urinary retention in the Japanese literature. The mechanism of urinary retention due to infantile gynecological disease is discussed.
该患者为一名20个月大的女童。她于1991年10月5日因排尿困难和尿痛前往某儿科诊所就诊。排泄性尿路造影、腹部超声和计算机断层扫描显示膀胱后有一肿块，向前上方压迫膀胱。她被转诊至我院作进一步评估。体格检查发现其下腹部有一个拳头大小的肿瘤，膀胱排空后该肿瘤依然存在。膀胱镜检查显示尿道延长，膀胱底部抬高。肿瘤标志物和内分泌检查均正常。入院两周后进行的磁共振成像显示，膀胱后肿瘤已移位至膀胱上方。于1991年10月29日进行了手术。肿瘤起源于右侧卵巢，大小为6.2×5.0×5.0厘米，重60克。手术标本的切面包括脂肪组织和毛发，病理诊断为卵巢皮样囊肿。这是日本文献中报道的表现为尿潴留的最年幼的卵巢皮样囊肿病例。本文讨论了婴幼儿妇科疾病导致尿潴留的机制。
