Knee replacements are common among older adults with painful joint arthritis. It has been assumed that the decrease in pain after recovery from joint replacement surgery translates into improved motion, strength, and function. But physical therapists working with these patients have noticed problems with climbing stairs and a slower walking speed long after recovery and rehab. Rehabilitation researchers around the world have confirmed these observations. Measures of muscle strength, CT scans showing muscle cross section, walking speed, and time to complete stairs have provided quantifiable evidence to back up this finding. Now similar results have been observed in patients who have a unilateral knee replacement (UKR). Unilateral knee replacement refers to an implant for half of the joint. Usually the medial side of the knee (closest to the other leg) is replaced most often because that's where most of the wear and tear occurs in many patients. In this study, physical therapists from Fin...
Alternative Names Hydronephrosis Symptoms Flank pain Abdominal mass Nausea and vomiting Urinary tract infection Fever Painful urination (dysuria) Increased urinary frequency Increased urinary urgency Note: Sometimes unilateral hydronephrosis does not have symptoms. Signs and tests Unilateral hydronephrosis is usually identified with tests such as the following: Abdominal MRI CT scan of the kidneys or abdomen Intravenous pyelogram (IVP) Isotope renography (special scan of the kidneys) Ultrasound of the kidneys or abdomen
Acute unilateral is a sudden blockage in one of the tubes (ureters) that drain urine from the kidneys.
Acute bilateral obstructive uropathy
Chronic unilateral obstructive uropathy
Chronic bilateral obstructive uropathy
Obstructive uropathy - unilateral - acute; Ureteral obstruction
Causes, incidence, and risk factors
Unilateral obstructive uropathy is most often caused by a kidney stone , although injury or other conditions could cause the disorder.
When urine flow is blocked, it backs up into the kidney. This leads to kidney swelling, also called hydronephrosis .
You have a greater risk for unilateral obstructive uropathy if you have ureteral stones and tumors, kidney stones, and tumors in nearby body structures such as the uterus and cervix .
Acute unilateral obstructive uropathy occurs in 1 in 1,000 people.
