Hydronephrosis that occurs acutely with sudden onset ( as caused by a kidney stone ) can cause intense pain in the flank area ( between the hips and ribs ).
32.
The obstruction may be either partial or complete and can occur anywhere from the calyces of the renal pelvis . Hydronephrosis can also result from the reverse flow of urine from the bladder back into the kidneys.
33.
It is responsible for 32 million cases of dysuria, 10 million cases of hydronephrosis, and 150, 000 deaths from renal failure annually, making " S . haematobium " the world s deadliest schistosome.
34.
This is generally done within the first few days after birth, although there is some risk that obtaining an imaging study this early may miss some cases of mild hydronephrosis due to the relative oliguria of a newborn.
35.
Finally, if hydronephrosis is significant and obstruction is suspected, such as a ureteropelvic junction ( UPJ ) or ureterovesical junction ( UVJ ) obstruction, a nuclear imaging study such as a MAG-3 scan is warranted.
36.
Renal abnormalities are reported in up to 38 % of patients with PMS . Vesicouretral reflux, hydronephrosis, renal agenesis, dysplasic kidney, polycystic kidney and recurrent urinary tract infections have all been reported in patients with PMS.

At CHOP, Dr . Shukla is the Director of Minimally Invasive Surgery with a keen clinical and research interest in robotic-assisted laparoscopy, urinary reflux, hydronephrosis, urinary tract reconstruction, hypospadias and disorders of sexual differentiation.
38.
These include underdevelopment or agenesis of the pancreas, adrenal glands, thymus, gallbladder, and thyroid; Hirschsprung's disease; gastric reflux, imperforate anus, retention testis, ectopic kidney, renal agenesis, and hydronephrosis.
39.
Alternately, severe bilateral prenatal hydronephrosis ( such as occurs with posterior urethral valves ) will likely carry a poor long-term prognosis, because obstruction while the kidneys are developing causes permanent kidney damage even if the obstruction is relieved postnatally.
40.
Diagnostic workup depends on the age of the patient, as well as whether the hydronephrosis was detected incidentally or prenatally or is associated with other symptoms . Blood tests ( such measurement of creatinine ) are typically indicated, though they must be interpreted cautiously.
