Clinical Information

• Ureterocele-. 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.
• Frasier Syndrome-. a syndrome characterized by chronic kidney failure and gonadal dysgenesis in phenotypic females with karyotype of 46,xy or female individual with a normal 46,xx karyotype. it is caused by donor splice-site mutations of wilms tumor suppressor gene (genes, wilms tumor) on chromosome 11.
• Ureteritis-. an acute or chronic inflammatory process affecting the ureter.
• Ureteritis Cystica-. a non-neoplastic lesion of the ureter characterized by the presence of multiple submucosal small cysts in the ureteral wall. it is caused by inflammation due to urinary tract stones or infection.
• Cecoureterocele-. a ureterocele in which the orifice is located in the bladder, with the ureterocele pouch extending submucosally into the urethra.
• Ectopic Ureterocele-. a ureterocele in which some portion of the ureterocele is situated permanently at the bladder neck or in the urethra. the orifice may be situated in the bladder, at the bladder neck, or in the urethra. (adapted from glassberg ki, braren v, duckett jw, jacobs ec, king lr, lebowitz rl et al. suggested terminology for duplex systems, ectopic ureters and ureteroceles. j urol 1984; 132(6):1153-1154.)
• Intravesical Ureterocele|Orthotopic Ureterocele-. a ureterocele that is located entirely within the bladder, and which may be associated with a single system, with the upper pole ureter of a completely duplicated system, or rarely associated with a lower pole ureter. (adapted from glassberg ki, braren v, duckett jw, jacobs ec, king lr, lebowitz rl et al. suggested terminology for duplex systems, ectopic ureters and ureteroceles. j urol 1984; 132(6):1153-1154.)
• Obstructive Ureterocele|Stenotic-. a ureterocele with a small, obstructive orifice.
• Sphincteric Ureterocele|Transsphincteric-. a ureterocele in which the orifice is distal to the external urinary sphincter.
• Ureterocele-. a cystic and dysplastic dilation of the distal ureter within the bladder that may extend into the bladder neck and urethra.
• Ureteric Fistula-. an abnormal communication between the ureter and another organ or anatomic site.
• Cardiorenal Syndrome-. a disorder of the heart and kidneys in which dysfunction of one of the organs induces dysfunction of the other organ.
• Frasier Syndrome-. a condition, which typically presents during adolescence, that is caused by wt-1 mutation, and is characterized by a developmental sex disorder, fsgs, and may be associated with gonadoblastoma.
• Malakoplakia-. an inflammatory reaction characterized by the presence of papules or nodules usually in the genitourinary tract. it is usually a reaction to an infection. morphologically, it consists of foamy histiocytes and characteristic basophilic inclusion bodies called michaelis-gutmann bodies.
• TEMPI Syndrome-. a rare syndrome characterized by telangiectasias, elevated erythropoietin level and erythrocytosis, monoclonal gammopathy, perinephric fluid collections, and intrapulmonary shunting. it is best classified as a type of plasma cell dyscrasia with paraneoplastic manifestations.

Diagnostic Related Groups - MS-DRG Mapping

The is diagnosis code is grouped in the following groups for version MS-DRG V40.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2022 through 09/30/2023.

Patient Education

Kidney Diseases

You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters. It goes to your bladder, which stores the urine until you go to the bathroom.

Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines. You have a higher risk of kidney disease if you have diabetes, high blood pressure, or a close family member with kidney disease. Chronic kidney disease damages the nephrons slowly over several years. Other kidney problems include:

• Cancer
• Cysts
• Stones
• Infections

Your doctor can do blood and urine tests to check if you have kidney disease. If your kidneys fail, you will need dialysis or a kidney transplant.

Ureteral Disorders

Your kidneys make urine by filtering wastes and extra water from your blood. The urine travels from the kidneys to the bladder in two thin tubes called ureters.

The ureters are about 8 to 10 inches long. Muscles in the ureter walls tighten and relax to force urine down and away from the kidneys. Small amounts of urine flow from the ureters into the bladder about every 10 to 15 seconds.

Sometimes the ureters can become blocked or injured. This can block the flow of urine to the bladder. If urine stands still or backs up the ureter, you may get a urinary tract infections.

Doctors diagnose problems with the ureters using different tests. These include urine tests, x-rays, and examination of the ureter with a scope called a cystoscope. Treatment depends on the cause of the problem. It may include medicines and, in severe cases, surgery.
