A review was done of 29 patients diagnosed with sacrococcygeal teratoma between 1978 and 1991. Urological disorders included total urinary retention (6 patients), hydronephrosis (6), hydrocele (4) and undescended testis (1). Ultrasonography and voiding cystourethrography were performed on the 6 patients in total urinary retention. These studies revealed cystic retrorectal lesions frequently with intralesional calcifications, and anterior and superior displacement of the bladder. Bladder wall trabeculation occurred in 2 of these 6 patients, and 4 had moderate or severe hydronephrosis. Upper urinary tract dilatation was found in 2 patients not in total retention. Hydronephrosis appeared to be related to poor bladder emptying and presumably high intravesical pressures, since each case resolved spontaneously after tumor resection. No primary upper tract anomalies were identified.
对1978年至1991年间诊断为骶尾部畸胎瘤的29例患者进行了回顾性研究。泌尿系统疾病包括完全性尿潴留（6例）、肾积水（6例）、鞘膜积液（4例）和隐睾（1例）。对6例完全性尿潴留患者进行了超声检查和排尿性膀胱尿道造影。这些检查发现直肠后囊性病变常伴有病灶内钙化，膀胱向前上方移位。这6例患者中有2例出现膀胱壁小梁形成，4例有中度或重度肾积水。2例非完全性尿潴留患者发现上尿路扩张。肾积水似乎与膀胱排空不良及推测的膀胱内高压有关，因为每例患者在肿瘤切除后均自行缓解。未发现原发性上尿路异常。
