Introduction:

The prenatal ultrasound provides a great way to introduce us to the human renal pathophysiology, but is unable to detect all of the anomalies.

Objectives:

To identify the main anomalies of the kidney and urinary tract in patients with prenatal or postnatal diagnosis of those.

Methods:

There were included in the study all the patients who were referred to the Nephrology Service of "William Soler" Pediatric Teaching Hospital from October 1, 2015 to September 30, 2017 being detected alterations in the prenatal ultrasound during the follow-up of a normal pregnancy and those in which after birth any abnormality was found incidentally or by related symptoms. Clinical, imaging and therapeutic follow-up were scheduled in accordance with the anomaly detected.

Results:

The study included 81 patients, 65 with prenatal diagnosis and 16 with post-natal finding. The male sex was represented by the 66.7% and the most common anomaly studied was the multicystic dysplastic kidney (23.4%). Secondly, the morphological diagnosis corresponded to dilations of the urinary tract, which in the post-natal study were classified as hydronephrosis (20.9%), pyelectasis (17.4%) and vesicoureteral reflux (7.4%).

Conclusions:

The prenatal ultrasound for the detection of kidney and urinary tract´s anomalies is a diagnosis of great utility because it allows us to prepare to face these anomalies before they present related symptoms and it can also provide adequate information to parents. Not all congenital anomalies are detected by prenatal ultrasound.
