title: [Study of the sensitivity of renal ultrasonography as an indirect means of assessing renal function in patients with neurogenic bladder, from a cohort of 103 patients].
abstract: OBJECTIVE
  The assessment of renal function is essential to follow up the patients with neurogenic bladder. The objective of this study was to determine if renal ultrasonography would both evaluate the morphology of the urinary tract and renal function.
  
  
  METHODS
  In a retrospective study, all patients followed for neurogenic bladder were included, regardless of their neurological disease. Renal function was estimated by creatinine clearance (Cl24 h), the reference test in neurological patients, the glomerular filtration rate by the MDRD simplified (MDRDs) and CKD-EPI creatinine formula, and we identified renal abnormalities detected on ultrasonography.
  
  
  RESULTS
  One hundred and three patients were included (57 men-36 women), mean age 51±13 years. Fifty-nine patients had multiple sclerosis, 23 spinal cord injury. Depending on the method used (Cl24h, MDRDs, CKD-EPI creatinine) respectively 54, 49 and 39 patients had abnormal renal function; eleven patients had abnormal findings on renal ultrasonography. The sensitivity of ultrasonography as an indirect indicator of renal function depending on the method used (Cl24h, MDRDs, CKD-EPI creatinine) was equal respectively to 14%, 8% and 10%.
  
  
  CONCLUSIONS
  Renal ultrasonography, which is essential to follow up the neurogenic bladder, is not enough sensitive to detect abnormal renal function and should continue to be associated with an evaluation of renal function, which is suitable for neurological patients.
