Most neonatal genitourinary problems are due to congenital anomalies. The first clues to urinary dysfunction are the quantity and quality of the urinary stream, and this should be scrutinized in every newborn. Common signs of dysfunction include anuria, hematuria, and masses. Anuria may be caused by obstruction, a vascular disorder, or renal agenesis or dysplasia. In the male, obstruction is commonly caused by posterior urethral valves. A mass may be a bladder distended by obstruction, a persistent urachus, a hydronephrotic or dysplastic kidney, or scrotal enlargement due to spermatic cord torsion.
大多数新生儿泌尿生殖系统问题是由先天性异常引起的。排尿功能障碍的最初线索是尿流的量和质，应对每个新生儿进行仔细检查。功能障碍的常见体征包括无尿、血尿和肿块。无尿可能由梗阻、血管疾病、肾缺如或发育异常引起。在男性中，梗阻通常由后尿道瓣膜引起。肿块可能是因梗阻而扩张的膀胱、持续性脐尿管、肾积水或发育异常的肾脏，或因精索扭转导致的阴囊增大。
