title: [Ultrastructural observation of detrusor in BPH patients].
abstract: OBJECTIVE
  To observe the detrusor ultrastructure in BPH patients and to investigate the relationship between detrusor instability and ultrastructure.
  
  
  METHODS
  The patients were divided into groups of detrusor instability(DI) and detrusor stability(DS) according to urodynamics examination. The structure of the detrusor were observed by light microscopy and transmission electron microscopy(TEM).
  
  
  RESULTS
  The intercellular intermediate junctions and cytoplasmic process junctions in DS were 11.34 +/- 3.23 and 4.26 +/- 1.78 respectively. The intercellular intermediate junctions decreased obviously (3.12 +/- 1.47, P < 0.01) instead of a large amount of cytoplasmic process junctions (26.37 +/- 7.14, P < 0.01) in DI.
  
  
  CONCLUSIONS
  There is a close relevance between intercellular junctions and DI. The observation of the ultrastructure of the detrusor is helpful for the diagnosis of BPH with DI and for the clinical treatment.
