Answer: Dilation of the renal pelvis
and calyces proximal to a blockage
The urinary tract obstruction is a
blockage of the flow of urine out of the body. It is characterized by the dilation
of the renal pelvis and calyces proximal to a blockage, which results to
hydronephrosis and progressive fall in glomerular filtration rate (GFR). 
Moreover,
it is expected that the obstruction is due to a reduction in nephron glomerular
filtration rate and a reduced number of filtering nephrons.

Explanation:
The disease called as the Osteogenesis imperfecta is the genetic disorder which causes imperfect formation of bones. This occurs due to abnormalities in the molecule of collagen which makes the matrix weak and  this causes multiple fractures of the bone even before birth in severe cases.  In milder cases the bones break with mild trauma.
