    Abstract:
    Sixteen female patients with colonic inertia and 12 control women underwent manometric evaluation of their bladder and rectal cavities. After subcutaneous injection of 0.035 mg./Kg. bethanechol, bladder intraluminal pressure increased by over 15 cm. water in 5 patients (31 per cent) and in none of the control group; maximal pressure after injection was 11.5 +/- 1.6 cm. H2O (mean +/- SE) in patients and 8.5 +/- 1 in controls (p less than 0.025). The intraluminal rectal pressure reached 23 +/- 4 cm. H2O in patients and only 11.9 +/- 1.4 in controls (p less than 0.0025). Time taken to reach a peak pressure was faster in patients both in bladder (17.4 +/- 0.7 vs. 19.8 +/- 1.2 minutes; p less than 0.01) and in the rectum 914.6 +/- 0.8 vs. 16.3 +/- 1.2; p less than 0.025). These findings and the clinical presentation suggest an autonomic neuropathic lesion in this group of patients.
