Abstract Purpose:We studied functional changes of bladder detruson in BPH patients combined with urinary retention.Methods:Bladder smooth muscle wall were taben while prostatectomy in 10 BPH patients with chronic retention and contrasted with two normal bladder wall by electron microscopy.Results:In BPH pntients path ophysiologic changes were revealed as follows:smooth muscle cell hypertrophy and disorganiged,cell junctions decrease,mainly connected by protrusion junctions. Mitochondria swelling,high electron dense deposition on cytomernbrane,cytoplasmie compositron of detached cell deseminated in intracellular space.Conclusions:From these changes we could make more correct comprehension of detrusor impaiment in BPH,and analysis the pathogenesis of BPH,even the effec tive management.
