Pyelocaliectasis ICD-10, Definition, Symptoms, Causes, Treatment | Pyelocaliectasis vs Hydronephrosis

In order to keep the body healthy and functioning properly, the urinary system is crucial. Pyelocaliectasis is a kidney disease that affects the renal pelvis and calyces. It is distinguished by the dilatation or enlargement of these structures, which might impede the normal flow of urine.

    Pyelocaliectasis Meaning

    Pyelocaliectasis is a condition that affects the kidneys, specifically the renal pelvis, and calyces. It is characterized by the dilation or enlargement of these structures, which can disrupt the normal flow of urine.

    Pyelocaliectasis Definition

    The term "pyelocaliectasis" describes the enlargement or dilation of the calyces and renal pelvis, two components of the kidney's collecting system. The renal pelvis is a funnel-shaped structure that gathers urine from the kidney and delivers it to the ureter. The renal pelvis delivers urine to the calyces, which resemble cup-like structures.

    Pyelocaliectasis Symptoms

    Pyelocaliectasis is frequently asymptomatic, which means it may not result in any obvious symptoms. However, persons with pyelocaliectasis may occasionally experience:

    Flank pain: 

    Discomfort or pain in the back or side, typically on one side.

    Urinary tract infections (UTIs): 

    Recurrent UTIs may occur due to the stagnant urine in the dilated renal pelvis and calyces.

    Blood in urine: 

    Hematuria, or the presence of blood in the urine, can be a sign of pyelocaliectasis.

    Frequent urination: 

    Increased frequency of urination, particularly during the night.

    Urinary urgency: 

    A sudden and strong urge to urinate.

    Pyelocaliectasis Causes

    There are many potential causes of pyelocaliectasis, including:

    Congenital abnormalities: 

    Some people are born with urinary system structural abnormalities, such as narrow ureters or a blockage that allows urine to back up into the renal pelvis and calyces.


    Pyelocaliectasis can be brought on by any obstruction in the urinary system, including kidney stones or tumors.

    Vesicoureteral reflux:

    This disorder develops when urine leaks from the bladder back into the kidneys, potentially causing the renal pelvis and calyces to enlarge.

    Urinary tract infections:

    Chronic or recurrent UTIs can contribute to the development of pyelocaliectasis.


    As individuals age, the urinary system may undergo changes that increase the risk of pyelocaliectasis.

    Pyelocaliectasis Treatment

    The following treatments may be taken into consideration if the pyelocaliectasis is causing symptoms or is linked to an underlying condition:


    Antibiotics may be recommended to treat and stop the recurrence of urinary tract infections if they are already present.


    Surgical intervention may be needed to eliminate obstructions that are contributing factors of pyelocaliectasis in order to restore normal urine flow.

    Endoscopic procedures:

    For the diagnosis and treatment of some disorders causing pyelocaliectasis, minimally invasive procedures like ureteroscopy or pyeloscopy may be employed.

    Symptomatic management:

    Pain medications and lifestyle modifications, such as drinking plenty of fluids and maintaining good urinary hygiene, may help alleviate symptoms associated with pyelocaliectasis.

    Pyelocaliectasis vs. Hydronephrosis

    The kidneys are affected by both pyelocaliectasis and hydronephrosis, however they differ significantly in several ways:

    The renal pelvis and calyces, which are a portion of the kidney's collecting system, are dilated or enlarged in pyelocaliectasis. It is frequently discovered by chance during imaging examinations and may and may not cause symptoms.

    Hydronephrosis is a condition when the entire kidney swells or enlarges as a result of a blockage that prevents urine from properly emptying. When left untreated, hydronephrosis, which is typically symptomatic, can result in significant pain and complications.

    Pyelocaliectasis ICD-10

    A medical disorder called pyelocaliectasis is characterized by enlargement of the renal pelvis and calyces.  There are various related codes that can be used to indicate the diagnosis for reimbursement purposes:

    N13.30: Unspecified hydronephrosis

    Q62.0: Congenital hydronephrosis

    N28.89: Other specified disorders of kidney and ureter

    N13.6: Pyonephrosis
