175 Possible Causes for Calyceal Dilation

  • Urinary Tract Infection

    VUR is graded from 1 to 5, with 1 being minor reflux into the ureter, and 5 being ureteral dilation and dilation of the renal pelvis and renal calyces.[clinicaladvisor.com]

  • Urethral Obstruction

    Ultrasound evaluation following referral to our center confirmed severe bilateral hydronephrosis with pelvic and calyceal dilatation, but amniotic fluid volume was normal[ncbi.nlm.nih.gov]

  • Chronic Gouty Nephropathy

    There is marked calyceal dilation, pyramidal effacement, and parenchymal thinning. (Courtesy V. Nickeleit, MD.)[basicmedicalkey.com]

  • Pelvic Hematoma

    There also was parenchymal atrophy and calyceal dilatation ( Figure 1 D).[academic.oup.com] The pelvis was dilated by an intraluminal mass.[academic.oup.com] The abdominal CT showed a 4 2 cm, enhancing soft tissue mass in the left renal pelvis, extending to the upper pole calyces and proximal ureter.[academic.oup.com]

  • Renal Artery Stenosis

    RPF is extending perirenally and at the level of the renal hilum with subsequent calyceal dilations (hydrocalycosis) associated with left renal artery stenosis.[ncbi.nlm.nih.gov]

  • Renal Tuberculosis

    Global enlargement of the affected kidney occurred when calyceal dilatation surpassed parenchymal retraction.[ncbi.nlm.nih.gov] Earliest findings include minimal calyceal dilatation with the loss of calyceal sharpness.[indianjnephrol.org] The CT scan showed signs of chronic nephropathy, dilated calyces and thinning of renal cortex in both kidneys and severe dilation of ureter.[ncbi.nlm.nih.gov]

  • Retroperitoneal Fibrosis

    RPF is extending perirenally and at the level of the renal hilum with subsequent calyceal dilations (hydrocalycosis) associated with left renal artery stenosis.[ncbi.nlm.nih.gov]

  • Vaginal Atresia

    Repeat abdominopelvic sonogram 6 months after surgery showed resolution of the calyceal dilatation, a normal sized vagina and an involuted uterus.[afrjpaedsurg.org] Early in the postoperative period, an elective abdominal sonogram revealed mild calyceal dilatation and thickened bladder wall, but there was no biochemical renal derangement[afrjpaedsurg.org]

  • Puerperium

    dilation may persist fro several months. how does the thyroid change in the puerperium?[quizlet.com] […] postpartum. a postpartum diuresis occur within 1-2 weeks after delivery and compensate for water retention during pregnancy. anatomic changes of pregnancy;such as ureteral and calyceal[quizlet.com]

  • Anterior Urethral Valve

    Upon diagnosis of true hypertension, an ultrasound of the child's renal tract showed evidence of marked hydronephrosis and calyceal dilatation.[academic.oup.com] In the latter, the calyceal dilatation may be minimal in spite of marked pelvic dilatation.[memoireonline.com] An urgent ultrasound of the child's urinary tract showed gross hydronephrosis bilaterally with calyceal dilatation (see Fig. 1 ).
