19. Antenatal hydronephrosis is the dilatation of the collecting
system of the fetal kidney.
It is estimated that fetal urinary tract dilatation is identified in
1% of all pregnancies.
In more than 50% cases, the antenatally detected dilatation is
transient and resolves spontaneously.
Antenatally detected dilatation, which persists after birth is
labeled as neonatal hydronephrosis.
Pelviureteric junction (PUJ) obstruction accounts for 50-60%
patients with neonatal hydronephrosis.
Vesicoureteric reflux (VUR) is detected in 20-30% of such
cases.
21. Fetal hydronephrosis of moderate degree can be
detected as early as 15-18 weeks gestation by
ultrasonography.
A maximum anteroposterior diameter of renal
pelvis of more than 10 mm and the ratio of
antero-posterior diameter of renal pelvis to
kidney of more than 0.5 after 30 weeks
gestation requires postnatal evaluation.
The ultrasound study should be repeated every
6-8 weeks until delivery.
26. Grade 1: Slight separation of the central renal
echo complex.
Grade 2: Renal pelvis is further dilated and a
single or a few calyces may be visualized.
Grade 3: Renal pelvis is dilated and there are
fluid filled calyces throughout the kidney, but
renal parenchyma is of normal thickness.
Grade 4: As grade 3, but renal parenchyma over
the calyces is thinned
27.

29. Asymptomatic unilateral hydronephrosis is most
often a benign condition.
Hydronephrosis due to PUJ obstruction resolves
spontaneously with passage of time.
Hydronephrosis & Hydroureteronephrosis due to
vesicoureteric junction obstruction improve.
Kidneys with renal pelvic diameter more than 20
mm are likely to show deterioration in renal
function, which might require intervention.
30. VUR is seen in 20-25% neonates with antenatally
detected hydronephrosis, more commonly in boys.
Forty per cent neonates with VUR show features
suggestive of renal scarring on DMSA scan.
Neonates with VUR should be managed on long-term
antibiotic prophylaxis (while awaiting spontaneous
resolution of the reflux).
The patients are kept on close follow-up for occurrence
of break-through urinary infections.
An ultrasound examination, and radionuclide cystogram
or MCU should be repeated at 12-15 months.
31. I Ureter only
II Ureter, pelvis, and calices; no dilatation; normal caliceal fornices
III Mild or moderate dilatation or tortuosity of the ureter and moderate
dilatation of the renal pelvis; no or slight blunting of the fornices
IV Moderate dilatation or tortuosity of the ureter and moderate dilatation
of the renal pelvis and calices; complete obliteration of the sharp
angle of the fornices but maintenance of the papillary impressions in
the majority of calices
V Gross dilatation and tortuosity of the ureter; gross dilatation of the
renal pelvis and calices; papillary impressions are no longer visible in
the majority of the calices
32.
33. Conservative Approach
The management of asymptomatic neonatal
hydronephrosis is essentially conservative.
severe neonatal hydronephrosis resolve
spontaneously and deterioration of renal function, if
detected, can be reversed by prompt surgery.
Antibiotic prophylaxis.
Cephalexin (10-15 mg/kg/day) should be used for
the initial 3 months, and cotrimoxazole (1-2
mg/kg/day) or nitro-furantoin (1 mg/kg/day).
Urine culture should be promptly obtained if the
patient has symptoms suggestive of urinary tract
infection e.g., unexplained fever, turbid or foul
smelling urine, poor feeding and lethargy
34. PUJ obstruction
At initial diagnosis
Presence of symptoms
Solitary kidney with hydronephrosis
Bilateral hydronephrosis
Differential renal function of obstructed kidney <30%
On follow-up Increasing renal pelvic dilatation >10%
decline in differential renal function
Posterior urethral valve,
ureterocele
Vesicoureteric reflux
Grade IV-V reflux persisting beyond infancy
New renal scars or recurrent urinary infections despite
antibiotic prophylaxis
