[The quantitative analysis of the x-ray changes in the kidney calices in chronic pyelonephritis in children]
Insights
A new fornicocervical index, calculated from renal calyce measurements, shows promise for diagnosing chronic pyelonephritis in children. This index may help differentiate chronic kidney inflammation from acute infections and other urinary tract issues.
Area of Science:
- Pediatric Nephrology
- Medical Imaging
- Urology
Background:
- Microbial inflammatory diseases of the urinary tract are common in children.
- Chronic pyelonephritis can lead to long-term kidney damage if not diagnosed promptly.
- Accurate diagnostic tools for pediatric urinary tract infections are crucial.
Purpose of the Study:
- To evaluate the fornicocervical index as an objective diagnostic criterion for chronic pyelonephritis in children.
- To assess the utility of the fornicocervical index in differentiating chronic pyelonephritis from acute pyelonephritis and other urinary tract infections.
- To establish a normal range for the fornicocervical index in healthy children.
Main Methods:
- A planimetric method was used to measure the fornix and cervix of renal calyces on excretory urography.
- The fornicocervical index was computed by multiplying these measurements.
- The index was calculated for 89 children with urinary tract diseases and 40 healthy controls.
Main Results:
- The fornicocervical index exceeded 24 units in the majority of children with chronic pyelonephritis.
- The index remained within normal limits (<24 units) in patients with acute pyelonephritis and general urinary tract infections.
- Seven false negative results were recorded in the study population.
Conclusions:
- The fornicocervical index appears to be a valuable objective criterion for diagnosing chronic pyelonephritis in children.
- This index may aid in distinguishing chronic pyelonephritis from other pediatric urinary tract inflammatory conditions.
- Further validation of the fornicocervical index in larger pediatric cohorts is warranted.
Abstract:
As many as 89 patients aged 6 months to 14 years with microbial inflammatory diseases of the urinary tract and 40 controls of the same age were examined. Of the patients, 55 had chronic pyelonephritis, 21 acute pyelonephritis, and 13 an infection of the urinary tract. For examination use was made of the planimetric method of measuring the width of the fornix and the cervix of the renal calyces on excretory urography. The fornicocervical index, product of the indicated parameters of the calyces, was computed. In health, that index did not exceed 24 units. In the majority of patients suffering from chronic pyelonephritis, it turned out higher. The false negative results were obtained in 7 cases. The fornicocervical index remained unchanged in patients with acute pyelonephritis and urinary tract infection. It is suggested that the fornicocervical index be computed for use as an objective criterion in the diagnosis of chronic pyelonephritis in children.
