A: ultrasound
13
11 GENITOURINARY SYSTEM: URINARY SYSTEM
Hydronephrosis
• •
Signs and Symptoms
Distention of renal pelvis and calices due to pressure from accumulating urine.
Pressure impairs, and may eventually interrupt, kidney function.
14
11 GENITOURINARY SYSTEM: URINARY SYSTEM
Hydronephrosis
• •
Signs and Symptoms (continued)
If obstruction is above bladder opening, only one kidney may be affected and person may be asymptomatic for a prolonged period.
If both kidneys are affected, symptoms may include intense pain, nausea, vomiting, oliguria or anuria, and hematuria.
15
11 GENITOURINARY SYSTEM: URINARY SYSTEM
Hydronephrosis
• • • • •
Treatment
Remove obstruction, prevent complications, and treat underlying disorders.
Catheterization for immediate relief of urinary pressure.
Analgesics may be prescribed.
Antibiotics are required if infection occurs.
Surgery if needed to dilate a ureteral stricture.
