99 Possible Causes for Pelvicalyceal Dilatation

  • Beta-Ureidopropionase Deficiency

    The clinical presentation of inborn errors of pyrimidine degradation varies considerably from asymptomatic to severe neurological illness. We have reported a method to screen for and make a chemical diagnosis of beta-ureidopropionase deficiency, leading to the discovery of the first asymptomatic case of this[…][ncbi.nlm.nih.gov]

  • Hydroureter

    The ipsilateral kidney, from which the megaureter originated, showed no pelvicalyceal dilatation.[ncbi.nlm.nih.gov] In 2006, intravenous urography showed moderate dilatation of both pelvicalyceal systems and ureters down to the level of urinary bladder.[casesjournal.biomedcentral.com] There was moderate dilatation of both pelvicalyceal systems and ureters down to the level of urinary bladder (Figure 5 and Figure 6 ).[casesjournal.biomedcentral.com]

  • Wolfram Syndrome

    Renal sonography showed pelvicalyceal dilatation in both kidneys equal to hydronephrose grade III with dilation in proximal of urethra and bladder enlargement.[casesjournal.biomedcentral.com] Since the diagnosis of diabetes mellitus, sonography of the abdomen was performed several times and pelvicalyceal dilatation was always found in both kidneys.[journals.viamedica.pl] Abdominal ultrasonography revealed dilated right pelvicalyceal system and small left kidney.[sjkdt.org]

  • Gastric Adenoma

    Additionally, hypoplastic left kidney and a millimetric calculus with mild pelvicalyceal dilatation were detected.[turkjem.org]

  • Urinary Tract Obstruction

    There was anhydramnios/oligohydramnios and pelvicalyceal dilatation in 20 and 15 cases, respectively.[ncbi.nlm.nih.gov] Although dilatation of the outflow system proximal to the site of obstruction is a characteristic finding, widening of the ureter and/or pelvicalyceal system does not necessarily[oxfordmedicine.com] Obstruction in a ureter causes dilation of the ureter (megaureter) and renal pelvicalyceal system (hydronephrosis).[patient.info]

  • Congenital Bilateral Absence of Vas Deferens

    Conversely, a fetus with obstruction may not have any urinary tract dilatation. Varying degrees of pelvicalyceal dilatation are found in about 1% of fetuses.[sonoworld.com] The degree of pelvicalyceal dilatation is variable and, occasionally, perinephric urinomas and urinary ascites may be present.[sonoworld.com] Moderate hydronephrosis, characterized by an anteroposterior pelvic diameter of more than 10 mm and pelvicalyceal dilatation, is usually progressive and in more than 50% of[sonoworld.com]

  • Renal Agenesis

  • Nonsyndromic Renal Hypodysplasia Type 1

    Conversely, a fetus with obstruction may not have any urinary tract dilatation. Varying degrees of pelvicalyceal dilatation are found in about 1% of fetuses.[sonoworld.com] The mother of the index case (III.4) is also asymptomatic and a renal US, performed in her fourth pregnancy, showed minimal bilateral pelvicalyceal dilatation, within normal[academic.oup.com] The degree of pelvicalyceal dilatation is variable and, occasionally, perinephric urinomas and urinary ascites may be present.[sonoworld.com]

  • Nephrolithiasis

    Absence of pelvicalyceal dilatation suggests that there is no obstruction to urinary flow.[ultrasound-images.com] Sonography shows no pelvicalyceal dilation or hydronephrosis despite extensive urolithiasis or nephrolithiasis (stone formation) in left kidney.[ultrasound-images.com]
