[The value of intravesical electrostimulation in the treatment of acute prolonged bladder overdistension].
BACKGROUND
The effectiveness of intravesical electrostimulation (IVES) in the treatment of acute prolonged bladder overdistension (PBO) was investigated.


METHODS
Sixteen patients (female 11, male 5, ø 54 years) after PBO (bladder filling volume: 1317+/-320 ml) were evaluated: 11 after surgery and 5 after polytrauma, psychosomatic disorder or LV4 fracture. After exclusion of a neurogenic aetiology and a urodynamic examination, IVES was performed besides IC or suprapubic catheter.


RESULTS
Group 1: six patients with a weak detrusor (p(detr. max.)<30 cmH(2)O); group 2: ten patients had detrusor acontractility. After 25 IVES sessions, group 1 showed a significant increase of p(detr. max.) (p=0.01) as well as a decrease in PVR (31% to 3% of bladder capacity, p=0.02). Group 2 had no significant increase of p(detr. max).


CONCLUSIONS
Two-thirds of patients with a weak detrusor after PBO will regain balanced voiding after IVES due to detrusor reinforcement. With an acontractile detrusor only bladder sensation improves.
