INTRODUCTION AND HYPOTHESIS: To determine the value of preoperative anal physiology testing and transanal ultrasonography in predicting clinical response to sacral neuromodulation for @entity1241 . METHODS: We report a retrospective study of all @entity1 treated with sacral neuromodulation for @entity1241 in a single practice between 2011 and 2014 was performed. @entity1 demographics included age, gender, comorbidities, presence of an ultrasound-defined external @entity1690 , and history of prior anal sphincter repair. @entity922 ( @entity922 ) scores were used to assess the severity of @entity1241 at baseline, and at 3, 6 and 12 months. Pearson's correlation coefficient was used to evaluate the relationship between preoperative physiology testing and ultrasonography and @entity1 outcome. RESULTS: Sacral neuromodulation was trialed in 60 @entity1 , of whom 31 had anorectal physiology testing and 29 did not. @entity1 who were tested were younger (60.9 vs. 71.4 years, p   =   0.013) and more likely to have had a prior overlapping sphincteroplasty (40.5% vs. 15%, p   =   0.043). Among @entity1 who progressed to complete system implantation, @entity922 scores at 3 and 12 months were similar whether they had physiology testing or not. Likewise, @entity1 outcome did not correlate with the finding of an ultrasound-defined external @entity1690 . Pearson's correlation coefficient was used to evaluate the relationship between the test results and the 3-month @entity922 scores. @entity922 scores 3 months after full system implantation did not correlate with the presence or size of an external @entity1690 , resting or squeeze pressure, pudendal nerve terminal motor latency, rectoanal inhibitory reflex, or minimum detectable volume. CONCLUSIONS: Anal physiology testing and ultrasonography were not predictive of clinical outcomes among @entity1 treated with sacral neuromodulation for @entity1241 .
