The effect of rectal distension on bladder function in patients with overactive bladder . AIMS To investigate the effect of rectal distension on bladder sensation volumes and the number of detrusor contractions in patients with overactive bladder ( OAB ) symptoms . METHODS A prospective randomized study included patients with OAB symptoms . Multichannel urodynamic studies were completed with and without rectal balloon distension . Bladder sensation volumes and detrusor contractions were compared . RESULTS Twenty-six patients were included in the study . The mean age was 67 years and mean BMI was 28.3 kg/m ( 2 ) . Bladder sensation volumes were lower with rectal distention as follows : normal desire to void ( 139 ml SD , ±114 vs. 197 ml SD ±150 , P = 0.01 ) , strong desire to void ( 260 ml SD ±171 vs. 330 ml SD ±172 , P = 0.01 ) , and maximum cystometric capacity ( 326 ml SD ±183 vs. 403 ml SD ±180 , P = 0.0001 ) . There was no difference in the number of detrusor contractions or the bladder volume at which the first detrusor contraction had occurred with and without rectal distension . CONCLUSION Rectal distention in patients with OAB symptoms significantly lowered bladder sensation volumes ( normal desire , strong desire , and maximal capacity ) .
