Pedlatrics has been shown during longitudinal conservative follow up of these children that the drainage might improve considerably and spontaneously, sometimes after several years[ 71 ]. Prenatal anteroposterior pelvic diameter cutoffs for postnatal referral for isolated pyelectasis and hydronephrosis: This needs to be diagnosed as early as possible so that intervention can be done before renal damage occurs.
Postnatal management of antenatally detected hydronephrosis
A stable dilated system at 6 years would not warrant further study except around puberty when it would be worthwhile having a look at the kidneys by ultrasound to rule out any deterioration of hydronephrosis with the spurt in growth that occurs.

Antenatall contrast, if the APD does not change in prone position or increases in prone position then these cases needed surgical intervention as their differential function showed a substantial drop[ 78 ]. However the agreement ends here.

Fetal and neonatal management. Article-Type of This Article. WB Saunders Co; ; Irrespective of the grade of hydronephrosis a repeat ultrasound is warranted at 4 wk after birth.
A close follow up with serial ultrasounds is recommended in this group[ 85 ]. Related articles Ultrasound hydronephrosis antenatal. Classification and clinical applications.
Studies have shown that the risk of infection increases with hyxronephrosis degree of hydronephrosis[ 28 – 31 ]. If the APD is used than the presence or absence of associated calyceal dilatation should also be mentioned.
Whatever system is followed, after the first postnatal ultrasound, the clinician should be able to categorize these patients in the mild, moderate and severe hydronephrosis categories so that further management can be decided[ 12 ]. These additional findings often contribute to establishing the postnatal diagnosis[ 20 ].
Curr Urol Rep ;3: However these studies are observational in nature and not standardized as regards, the method of urine collection, definition of infection, selection of patients for voiding cystourethrogram and use of prophylactic antibiotics. The hydronephrosis index is defined by the APD of the fetal kidney divided by the urinary bladder volume. Ultrasonography at d would show one of the following scenarios: At present, this seems to be the simplest way of differentiating a dilated but non obstructed system indin a dilated and obstructed system.
Prenatal diagnosis and treatment of obstructive uropathies.
Thus there is impediment of the emptying of the renal pelvis resulting in urinary stasis in the renal pelvis. The landmark study by Dhillon et al[ hydroenphrosis ] inproposed the measurement of APD of the renal pelvis as a means of judging the severity of hydronephrosis and predicting the need for surgery.

Anomalies of antematal upper tract. Constantinou[ 39 ] suggested that a pacemaker in the renal pelvis activates the smooth muscle of the renal pelvis to initiate peristaltic contractions.
How to cite this article: Ultrasound Obstet Gynecol ; Infants with bilateral hydronephrosis are at an increased risk of infection compared to children with unilateral hydronephrosis. The risk of renal function deterioration is high in this group[ 36 ].
