Change in urethral sphincter neuromuscular function during pregnancy persists after delivery.

Objective: The purpose of this study was to assess the effect of pregnancy and first vaginal delivery on urethral striated sphincter neuromuscular function.

Study Design: Quantitative electromyographic (EMG) interference pattern analysis of the urethral sphincter of 23 nulligravidas and 31 third trimester primigravidas allowed comparison of mean motor unit parameters before term vaginal delivery and postpartum.

Results: Mean electromyographic interference pattern parameters in the primigravidas were significantly lower than nulligravidas even antepartum, with decreased turns, lower amplitude, and less activity.

Levator ani denervation and reinnervation 6 months after childbirth.

Objective: The objective of the study was to assess the prevalence of levator ani denervation and reinnervation 6 months after the first delivery.

Study Design: Ninety-six primigravida women underwent quantitative electromyography of the levator ani during the third trimester and twice postpartum. A 95% confidence interval for normal function was created using interference pattern analysis.

Early vs late midline sling lysis results in greater improvement in lower urinary tract symptoms.

Objective: Lower urinary tract symptoms (LUTS) occur in 5-20% of women after antiincontinence procedures. Symptoms include complete urinary retention or storage, voiding, and postmicturition symptoms. The goal of this study was to determine the effect of time from sling placement to midline sling lysis on overall improvement in LUTS.

Surgical excision of eroded mesh after prior abdominal sacrocolpopexy.

Objective: We previously described an endoscopic-assisted transvaginal mesh excision technique. This study compares surgical outcomes after transvaginal mesh excision vs endoscopic-assisted transvaginal mesh excision. In addition, we reviewed our postoperative outcomes with excision via laparotomy.

Detrusor overactivity does not predict outcome of sacral neuromodulation test stimulation.

The aim of this study is to determine if urodynamic findings in patients with urge incontinence predicts response to sacral neuromodulation test stimulation. One hundred four patients with refractory urinary urge incontinence who had undergone sacral neuromodulation test stimulation were retrospectively reviewed. Pre- and post-test stimulation incontinence parameters and pelvic floor muscle (PFM) contraction strength was documented.

The use of non-nutritive sucking to decrease the physiologic pain response during neonatal circumcision: a randomized controlled trial.

Objective: The purpose of this research was to study the effects on the physiologic pain response of the neonate during circumcision with the use of a gloved human finger.

Study Design: This was a randomized controlled trial analyzing the effect of non-nutritive sucking (NNS) on pain response during circumcision. Term neonates were randomized to 2 groups.
