title: [The application of noninvasive urodynamics in early detection of diabetic cystopathy].
abstract: OBJECTIVE
  To evaluate the early detection of diabetic cystopathy (DCP) with the technology of noninvasive urodynamics.
  
  
  METHODS
  70 patients with type 2 diabetes mellitus (DM) and 30 normal control subjects were checked with the technology of noninvasive urodynamics. Based on their disease course of less or more than 5 years, the DM patients were divided into two groups. Maximal flow rate, average flow rate, the volume leading to first bladder sensation and residual urine volume were measured by using noninvasive urodynamic technology.
  
  
  RESULTS
  Among the 70 DM patients, 34 were detected to have bladder residual urine, so the DCP detection rate was 48.6%. In the patients with DCP, the average residual urine volume was 7-139 ml (30.1 +/- 27.1) ml, while there was no residual urine in the normal control group. As compared with the normal control group, maximal flow rate and average flow rate were decreased in all the patients with DM and those with DCP (P < 0.01). After follow up of the disease, the patients with a course of more than five years of disease control had even lower maximal flow rate and average flow rate.
  
  
  CONCLUSIONS
  Maximal flow rate decrease and bladder residual urine detected with the technology of noninvasive urodynamics may be widely used in early detection and early diagnosis of DCP.
