This study reports two cases of prenatal ultrasound diagnosis of ectopic ureter and bilateral renal hypoplasia in two different canine fetuses. These developmental disorders were detected during a routine pregnancy ultrasound examination of a female Golden retriever and a female Old English bulldog. A suspected diagnosis of ectopic ureter was made based on the ultrasonographic detection of fetal kidney hydronephrosis and ureteral dilatation, along with consideration of breed predisposition. Bilateral fetal renal hypoplasia presented with ultrasonographic detection of reduced, hyperechogenic fetal kidneys without a distinguishable renal pelvis. Ultrasonographic findings were subsequently confirmed postnatally at surgery or autopsy and histopathology. Our findings highlight the potential for early detection of urogenital anomalies in canines and the importance of knowledge of normal fetal anatomy during ultrasound examination of pregnancy.
本研究报告了两例不同犬类胎儿产前超声诊断异位输尿管和双侧肾发育不全的病例。这些发育障碍是在对一只雌性金毛猎犬和一只雌性英国古代斗牛犬进行常规妊娠超声检查时发现的。基于超声检测到胎儿肾积水和输尿管扩张，并考虑品种易感性，做出了异位输尿管的疑似诊断。双侧胎儿肾发育不全表现为超声检测到胎儿肾脏缩小、回声增强，无明显肾盂。超声检查结果随后在出生后通过手术、尸检和组织病理学得到证实。我们的研究结果强调了早期检测犬类泌尿生殖系统异常的可能性，以及在妊娠超声检查中了解正常胎儿解剖结构的重要性。
