If there is no increasing hydronephrosis on serial ultrasounds then also the child needs to be followed up till the age of 6 years. Prenatal puncture of a unilateral hydronephrosis leading to fetal urinoma and postnatal nephrectomy.

The diagnosis of fetal pelvis dilatation and hydroneprosis natural history postnatally is best understood if we understand that the definition of hydronephrosis has undergone a sea change. The antenatal ultrasound screening is most commonly performed at wk of gestation. In cases of posterior urethral valves the level of amniotic fluid is a significant predictor of renal function and clinical outcome[ 21 ].

At present fetal intervention is indicated in cases where the life of the fetus is at risk, typically a second trimester fetus with significant oligohydramnios, suspected good inian function and absence of other life threatening anomalies[ 21 ]. Current management of infants with fetal renal pelvis dilation: The available literature is conflicting.

WB Saunders Company; ; J Korean Med Sci. The exceptions antenaatal this caveat are: However this grading system is not universally followed and due to the ambiguity in inter and intra observer agreement especially in grade 3 and grade 4 hydronephrosis, modifications have been proposed[ 1718 ].

Revised guidelines on management of antenatal hydronephrosis.

This probably explains the disappearing fetal hydronephrosis postnatally when the physiological function of the urinary tract becomes more mature. Clinical characteristics and outcome of hydronephrosis detected by prenatal ultrasonography. British Association of Paediatric Urologists consensus statement on the management of the primary obstructive megaureter.

This needs to be diagnosed as early as possible so that intervention can be done before renal damage occurs.

Intrauterine diagnosis of renal anomalies by ultrasonography. However the agreement ends here. Surgery versus observation for managing obstructive grade 3 to 4 unilateral hydronephrosis: Also once the bladder is empty, the effect of a distended bladder on the filling and emptying of the collecting system resulting in fallacious diagnosis of pyelectasis is avoided. The hydronephrosis index is defined by the APD of the fetal kidney divided by the urinary bladder volume.

Till an answer to this dilemma is obtained, there is much parental anxiety, as the need for surgery hangs like a sword of Damocles on the head of the patient. Investigators have studied whether ultrasonography can be used to predict the need for surgery. Though there are defined criteria of intervention, it is still not clear as to who will benefit.
