A 3 year old girl tests positive for an upper urinary tract infection.  Two years later, while returning for another annual doctor’s appointment, the now 5 year old child complains of weakness, loss of appetite, and pain on her backside.  After taking the child's blood pressure, the doctor notices possible hypertension, since the child's last visit.  The physician decides to run another urinalysis to figure out what is causing the young girl's most recent symptoms.  The results of the urinalysis were as follows:

 

Color	Yellow	Protein	300	Blood	Negative
Appearance	Cloudy	Glucose	Negative	Urobilinogen	0.2
Sp. Gravity	1.015	Ketones	Negative	Nitrite	Positive
pH	7.0	Bilirubin	Negative	Leukocyte	Moderate

Microscopic
20-50 wbc/hpf
0-2 rbc/hpf
Moderate bacteria present
5-10 renal epithelial cells/hpf
2-5 granular cast/lpf
1-3 wbc casts/lpf

Blood creatinine level- normal

2. If the young patient has hypertension, what affects would this have on cast formation in correlation with the evidence provided?  Answer
