Obsolete Disorders of the Ureter

There are several outdated terms that were once used to describe various disorders affecting the ureters, which are the tubes that carry urine from the kidneys to the bladder.

• Congenital Deviation of Ureter: This term was used to describe a congenital anomaly where the ureter is abnormally positioned or deviated. [1] However, with advancements in medical knowledge and terminology, this condition is now more accurately described as a congenital anomaly of the urinary tract.
• Ureteral Disease: This term was once used to describe any disorder affecting the ureters, including both non-neoplastic and neoplastic conditions. [4][12] However, with the development of more specific and accurate terminology, this term is now considered obsolete.
• Ureteric Disease: Similar to "ureteral disease", this term was also used to describe any disorder affecting the ureters. [4]
• Primary Megaureter (PM): This condition was once described as a primary megaureter, where the cause of the megaureter was idiopathic. [7] However, with further research and understanding, this condition is now more accurately described as an idiopathic megaureter.

It's essential to note that these terms are no longer used in modern medical practice and have been replaced by more accurate and specific terminology.

Symptoms of Ureteral Obstruction

Ureteral obstruction, although considered an obsolete disorder in modern medical practice, can still manifest itself through various signs and symptoms.

• Flank Pain: One of the most common symptoms is flank pain, which can be intermittent and worsen with increased fluid intake or consumption of certain beverages like alcohol or coffee [1][5].
• Abdominal Pain: The pain may radiate to the front of the abdomen and down to the groin area [15].
• Blood in Urine (Hematuria): In some cases, people with ureteral obstruction may experience blood in their urine [1].
• Recurrent Urinary Tract Infections: If the blockage is not treated, it can lead to recurrent urinary tract infections due to the stagnation of urine [13].

Other Possible Symptoms

While less common, other symptoms that may be associated with ureteral obstruction include:

• Swelling of the legs
• Fatigue (tiredness)
• Loss of appetite

It's essential to note that these symptoms can also be indicative of other underlying conditions. If you're experiencing any of these symptoms, it's crucial to consult a healthcare professional for proper diagnosis and treatment.

Based on the available information, it appears that there are several diagnostic tests that were used in the past to diagnose disorders related to the ureter.

• Intravenous Urography (IVU): This test was once considered a standard for diagnosing acute flank pain and has been replaced by non-contrast-enhanced computed tomography (CT) scans [4]. IVU images can also demonstrate the typical appearance of a retrocaval ureter, which is an obsolete disorder of the ureter [1].
• Retrograde Ureterogram: This test was used to diagnose disorders related to the ureter, such as obstruction or stones. However, it requires anesthesia and is not commonly used today.
• Urine Dipstick Testing: While this test is still used today to identify microhaematuria, it may have been used in the past to help diagnose disorders related to the ureter.

It's worth noting that modern diagnostic tests for ureteral disorders include:

• Low-dose CT scans: These are now considered the standard for diagnosing acute flank pain and other ureteral disorders [4].
• Ureteroscopy: This is a minimally invasive procedure used to diagnose and treat ureteral stones, among other conditions. It has been shown to have higher stone-free rates compared to extracorporeal shockwave lithotripsy (ESWL) [5].

Based on the provided context, it appears that there are various treatment options for disorders related to the ureter. However, I couldn't find any specific information on a "obsolete" disorder of the ureter.

That being said, I can provide some general information on the treatment of ureteral disorders. According to search result [10], the goal of treating ureteral obstruction is to remove blockages or bypass them, which may help repair damage. Treatment often involves surgery to remove blockages and repair any damage to the ureters and kidneys.

In terms of drug treatment, I couldn't find any specific information on a "obsolete" disorder of the ureter. However, search result [9] mentions that ureteral stents have a major role in urology and are used mainly to achieve correct renal drainage. Ureteral stents are very effective and can be used as a treatment option for certain ureteral disorders.

It's worth noting that the term "obsolete" is not commonly used in medical literature, and it's possible that this is a specific or outdated term that I couldn't find any information on.

If you could provide more context or clarify what you mean by "obsolete disorder of the ureter," I may be able to provide more relevant information.

Based on the provided context, it appears that there are several differential diagnoses for disorders related to the ureter. Here are some possible answers:

Congenital Hydronephrosis: This condition is a differential diagnosis for disorders affecting the ureter, particularly when considering congenital conditions (see [7], [14]). It involves an abnormal dilation of the renal pelvis and calyces, which can be caused by various factors such as obstruction or reflux.

Polycalycosis and Hydrocalycosis: These conditions are also differential diagnoses for disorders affecting the ureter, particularly when considering congenital conditions (see [7], [14]). Polycalycosis refers to an increase in the number of calyces, while hydrocalycosis involves an abnormal dilation of the calyces.

Vesico-ureteric Reflux: This condition is a differential diagnosis for disorders affecting the ureter, particularly when considering conditions that may cause calyceal blunting (see [14]). It involves the retrograde flow of urine from the bladder into the ureters and kidneys.

Megacalycosis: This condition refers to an increase in size of the calyces in the affected kidney (see [14]). It is a differential diagnosis for disorders affecting the ureter, particularly when considering conditions that may cause calyceal enlargement.

These are some possible differential diagnoses for obsolete disorders related to the ureter. However, it's essential to note that these conditions might not be directly relevant to modern medical practice or current research in the field of urology.
