Label	Id	Description
Unilateral Breast Neoplasms	D000069584	[Tumors or cancer found specifically in the human left BREAST., Tumors or cancer found specifically in one human BREAST, but not in both., Tumors or cancer found specifically in the human right BREAST.]
Uniparental Disomy	D024182	[The presence in a cell of two paired chromosomes from the same parent, with no chromosome of that pair from the other parent. This chromosome composition stems from non-disjunction (NONDISJUNCTION, GENETIC) events during MEIOSIS. The disomy may be composed of both homologous chromosomes from one parent (heterodisomy) or a duplicate of one chromosome (isodisomy)., The presence in a cell of a chromosome pair that is composed of both homologous chromosomes from one parent., The presence in a cell of a chromosome pair that is composed of duplicates of one parental chromosome.]
Unverricht-Lundborg Syndrome	D020194	[An autosomal recessive condition characterized by recurrent myoclonic and generalized seizures, ATAXIA, slowly progressive intellectual deterioration, DYSARTHRIA, and intention tremor. Myoclonic seizures are severe and continuous, and tend to be triggered by movement, stress, and sensory stimuli. The age of onset is between 8 and 13 years, and the condition is relatively frequent in the Baltic region, especially Finland. (From Menkes, Textbook of Child Neurology, 5th ed, pp109-110)]
Upper Extremity Deep Vein Thrombosis	D056824	[Spontaneous DEEP VEIN THROMBOSIS of an upper extremity vein, mostly AXILLARY VEIN; and SUBCLAVIAN VEIN. It is frequently precipitated by repetitive physical activity often in young, healthy adults., DEEP VEIN THROMBOSIS of an upper extremity vein (e.g., AXILLARY VEIN; SUBCLAVIAN VEIN; and JUGULAR VEINS). It is associated with mechanical factors (Upper Extremity Deep Vein Thrombosis, Primary) secondary to other anatomic factors (Upper Extremity Deep Vein Thrombosis, Secondary). Symptoms may include sudden onset of pain, warmth, redness, blueness, and swelling in the arm., DEEP VEIN THROMBOSIS of an upper extremity vein (e.g., AXILLARY VEIN; SUBCLAVIAN VEIN; and JUGULAR VEINS) that develops as a complication of upper extremity central venous catheters and pacemaker uses, or cancer.]
Upper Extremity Deformities, Congenital	D038062	[Congenital structural abnormalities of the UPPER EXTREMITY.]
Urachal Cyst	D014496	[Cyst occurring in a persistent portion of the urachus, presenting as an extraperitoneal mass in the umbilical region. It is characterized by abdominal pain, and fever if infected. It may rupture, leading to peritonitis, or it may drain through the umbilicus.]
Urea Cycle Disorders, Inborn	D056806	[Rare congenital metabolism disorders of the urea cycle. The disorders are due to mutations that result in complete (neonatal onset) or partial (childhood or adult onset) inactivity of an enzyme, involved in the urea cycle. Neonatal onset results in clinical features that include irritability, vomiting, lethargy, seizures, NEONATAL HYPOTONIA; RESPIRATORY ALKALOSIS; HYPERAMMONEMIA; coma, and death. Survivors of the neonatal onset and childhood/adult onset disorders share common risks for ENCEPHALOPATHIES, METABOLIC, INBORN; and RESPIRATORY ALKALOSIS due to HYPERAMMONEMIA.]
Ureaplasma Infections	D016869	[Infections with bacteria of the genus UREAPLASMA.]
Uremia	D014511	[A clinical syndrome associated with the retention of renal waste products or uremic toxins in the blood. It is usually the result of RENAL INSUFFICIENCY. Most uremic toxins are end products of protein or nitrogen CATABOLISM, such as UREA or CREATININE. Severe uremia can lead to multiple organ dysfunctions with a constellation of symptoms.]
Ureteral Calculi	D014514	[Stones in the URETER that are formed in the KIDNEY. They are rarely more than 5 mm in diameter for larger renal stones cannot enter ureters. They are often lodged at the ureteral narrowing and can cause excruciating renal colic.]
Ureteral Diseases	D014515	[Pathological processes involving the URETERS.]
Ureteral Neoplasms	D014516	[Cancer or tumors of the URETER which may cause obstruction leading to hydroureter, HYDRONEPHROSIS, and PYELONEPHRITIS. HEMATURIA is a common symptom.]
Ureteral Obstruction	D014517	[Blockage in any part of the URETER causing obstruction of urine flow from the kidney to the URINARY BLADDER. The obstruction may be congenital, acquired, unilateral, bilateral, complete, partial, acute, or chronic. Depending on the degree and duration of the obstruction, clinical features vary greatly such as HYDRONEPHROSIS and obstructive nephropathy.]
Ureterocele	D014518	[A cystic dilatation of the end of a URETER as it enters into the URINARY BLADDER. It is characterized by the ballooning of the ureteral orifice into the lumen of the bladder and may obstruct urine flow.]
Ureterolithiasis	D053039	[Formation of stones in the URETER.]
Urethral Diseases	D014522	[Pathological processes involving the URETHRA.]
Urethral Neoplasms	D014523	[Cancer or tumors of the URETHRA. Benign epithelial tumors of the urethra usually consist of squamous and transitional cells. Primary urethral carcinomas are rare and typically of squamous cells. Urethral carcinoma is the only urological malignancy that is more common in females than in males.]
Urethral Obstruction	D014524	[Partial or complete blockage in any part of the URETHRA that can lead to difficulty or inability to empty the URINARY BLADDER. It is characterized by an enlarged, often damaged, bladder with frequent urges to void.]
Urethral Stricture	D014525	[Narrowing of any part of the URETHRA. It is characterized by decreased urinary stream and often other obstructive voiding symptoms.]
Urethritis	D014526	[Inflammation involving the URETHRA. Similar to CYSTITIS, clinical symptoms range from vague discomfort to painful urination (DYSURIA), urethral discharge, or both.]
