The value of intravesical electrostimulation in the treatment of acute prolonged bladder overdistension

Backgroung. The effectiveness of intravesical electrostimulation (IVES) in the treatment of acute prolonged bladder overdistension (PBO) was investigated. Methods. Sixteen patients (boxed times 11, boxed times 5, circle divide 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). Conclusion. 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.
