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/m2 . 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).
