Twenty patients with hydronephrosis in whom examination with ultrasound was helpful in defining the extent of dilation of the collecting system are presented. Thirteen patients had hydronephrosis due to obstruction at the ureteropelvic junction, six had obstruction of the ureterovesical junction from various causes, and one had massive bilateral vesicoureteral reflux. The diagnosis of high ureteral obstruction as opposed to obstruction or reflux at the ureterovesical junction was based on visualizing a dilated ureter in the later two groups.
本文介绍了20例肾积水患者，超声检查有助于明确其集合系统的扩张程度。其中13例患者的肾积水是由于肾盂输尿管连接处梗阻所致，6例患者因各种原因导致输尿管膀胱连接处梗阻，1例患者存在大量双侧膀胱输尿管反流。与输尿管膀胱连接处梗阻或反流不同，高位输尿管梗阻的诊断依据是在后两组患者中观察到扩张的输尿管。
