However the clinician is worried about the possibility of infection in a dilated system with stasis of urine.

Postnatal management of antenatally detected hydronephrosis

Correlation of hydronephrosis index to society of fetal urology hydronephrosis scale. Percutaneous fetal cystoscopy and endoscopic fulguration of posterior urethral valves. 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 risk of renal function deterioration is high in this group[ 36 ]. However they have not gained universal acceptance and also there values have not been standardized. Lessons Learned after 16 Years of Follow-Up.

Antenatal hydronephrosis current evaluation and management Mathews R – Indian J Urol

While the APD measurement provides an objective means of predicting pathology, many felt that other features are also important in determining the severity of hydronephrosis. Interventions for primary vesicoureteric reflux. Clinical characteristics and outcome of hydronephrosis detected by prenatal ultrasonography.


Open-Access Policy of This Article. Also does it alter the prognosis significantly and does the benefit outweigh the risks should be evaluated diligently. Related articles Ultrasound hydronephrosis antenatal.

Mild pyelectasis diagnosed by prenatal ultrasound is not a predictor of urinary tract morbidity in childhood. An alternative grading system to refine the criteria for severity of hydronephrosis and optimal treatment guidelines in neonates with primary UPJ-type hydronephrosis.

The management of this condition has raised considerable debate amongst clinicians dealing with it. The following should be the aim of doing this evaluation using a tool which is easily available, provides good anatomical information, is non invasive and is not associated with any radiation: Also, guidelines have been given to facilitate the management of this condition.

Hydronephgosis there is a dilated system, the tracer, even under the influence of frusemide has to fill the renal pelvis before leaving the kidney, even if there is no significant restriction to urinary flow. A radionuclide study at 6 years, before stopping follow up, would be useful to confirm the good functional status of the kidney and establish a baseline value for further comparison in future. Sibai et al[ 60 ] proposed sub classifying SFU grade 4 into Grade 4 A-with segmental cortical thinning and Grade 4 B-diffuse cortical thinning.

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

Revised guidelines on management of antenatal hydronephrosis.

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 timing of VCUG in this group of patients should be at wk. When and how to evaluate Initially?

The aim of evaluation by noninvasive and inexpensive modality like ultrasonography is to diagnose those patients at risk of deterioration of renal function, differentiate them from those who indan do well in the long run and help in judiciously utilizing renogram to intervene at the optimum moment before renal function is affected. Analysis of trends on serial ultrasound for high grade neonatal hydronephrosis.

Do infants with mild prenatal hydronephrosis benefit from screening for vesicoureteral reflux? Fetal Diagn Ther ; However given the subjective nature of sonography and the factors like maternal hydration affecting the measurements, this issue has not been resolved as of today and hence clinicians should follow a standard classification and grade the dilatation as mild, moderate and severe as suggested in Antenatxl 2.

Fanos V, Cataldi L. Antenatal detection of pelviureteric junction stenosis: Hydronephrodis has been speculated by Leung et al[ 19 ] that the pacemaker in the renal pelvis does not mature at an early gestational age. A multicenter outcomes analysis of patients with neonatal reflux presenting with prenatal hydronephrosis. Accuracy of renal-bladder ultrasonography as a screening method to suggest posterior urethral valves.
