Urethro-vaginal reflux during micturition: An underestimated cause of urinary incontinence in adult women.

AIMS: To evaluate if urethrovaginal reflux (UVR) is an underestimated cause of insensible or postmicturition incontinence in adult women. METHODS: An observational and retrospective study was carried out on the computerized records of a neuro-urology department. Female patients who had insensible or postmicturition incontinence were investigated. Retrograde and voiding urethrocystography (UCG), urodynamic evaluation, urethral pressure profilometry, and anamnestic and clinical examination had to be available. RESULTS: Among the 79 adult female patients with insensible or postmicturition incontinence in whom the whole set of required evaluations was achieved, 16 had a UVR (mean age 47 ± 15 years). There were no urethral diverticula, urethrocele, vesicovaginal, or urethrovaginal fistula on their UCG. All of them also had a cystoscopy and a CT urography which did not establish any abnormality. CONCLUSIONS: UVR is not an exclusive pathology of children. This mechanism seems to be an underestimated cause of urinary incontinence in adult women. Retrograde and voiding UCG appears to be the gold standard to confirm the intravaginal reflux.

French clinical guidelines for peripheral motor nerve blocks in a PRM setting.

INTRODUCTION: Motor nerve blocks with anesthetic drug for local anesthesia are commonly used in physical and rehabilitation medicine (PRM), especially in the field of spasticity. Guidelines in this context are currently lacking. METHOD: Eighteen experts selected on the basis of their recognized experience by the scientific committees of the French PRM (SOFMER) and Anesthesia and Intensive care (SFAR) societies were invited to work and propose guidelines for the use of loco-regional anesthetic drug for motor nerve blocks in PRM setting. Eight issues were addressed: which neural blocks for which indications; drugs and contraindications; medical survey and attitude in case of adverse event; injection and guidance material; patient preparation and pain relief; efficacy assessment; patient information; education of PRM physiatrists. The Medline, Cochrane and Embase databases for the period 1999 to 2018 were consulted and 355 papers analyzed. The drafts were commented then approved by the whole group using electronic vote, before final approval by scientific committee of each society. RESULTS: No scientific evidence emerged from the literature. Thus, these guidelines are mainly based on the opinion of the expert panel. Guidelines for each issue are reported with the main points of arguments. The main question deals with the recommendation about doses for each drug: for lidocaine - up to 2mg/kg - "check contraindications, emergency truck available, no need of previous anesthetic consultation nor presence of anesthetic physician"; for ropivacaine - up to 1.5mg/kg, with a maximum of 100mg - the same but after intravenous line. Beyond these doses, SFAR guidelines have to be applied with the need of anesthetic physician. CONCLUSION: These are the first organizational guidelines devoted to increase the security of motor nerve block use in PRM settings.

Diffusion-Weighted Magnetic Resonance Imaging: A New Tool for the Diagnosis of Bladder Pain Syndrome/Interstitial Cystitis.

OBJECTIVES: To determine whether diffusion-weighted magnetic resonance imaging (DWMRI), a noninvasive procedure, can contribute to the diagnosis of bladder pain syndrome/interstitial cystitis (BPS/IC). METHODS: The pelvic DWMRI of patients with chronic pelvic pain syndrome was selected between January 2012 and June 2017. A radiologist analyzed the bladder wall signal; he was blinded to the patients' clinical data. According to the 2008 European Society for the Study of Bladder Pain Syndrome/Interstitial Cystitis criteria, 2 groups of patients were determined: BPS/IC and no BPS/IC. The association between BPS/IC and the wall signal intensity was compared. RESULTS: In the 106 patients included, 82 had criteria for BPS/IC and 24 did not. A significant difference in the distribution of the signal was found between the 2 groups (p = 0.01). High signal intensity of the bladder wall was related to the presence of a BPS/IC with a sensitivity of 28% and a specificity of 88%. No signal intensity of the bladder wall was related to the absence of a BPS/IC with a sensitivity of 96% and a specificity of 29%. CONCLUSIONS: In -DWMRI, high bladder wall signal intensity helps to affirm a BPS/IC, whereas the absence of signal helps to exclude the diagnosis. Further studies are needed to confirm these preliminary results.

Posterior vaginal wall pull down maneuver: a clinical test to diagnose intrinsic sphincter deficiency in women suffering from genuine urinary stress incontinence.

OBJECTIVES: To assess the predictive value of a simple clinical test (posterior vaginal wall pull down maneuver) in the diagnosis of intrinsic sphincter deficiency. METHODS: The present prospective study included 62 women suffering from stress urinary incontinence. Every patient underwent a urogynecological examination including multichannel urodynamic testing (cystometry, urethral pressure profile, Valsalva Leak Point Pressure measurement) and a clinical examination including posterior vaginal wall pull down maneuver. Posterior vaginal wall pull down maneuver was carried out with the bladder filled with 400 mL of saline in a supine position, and was obtained by means of a split speculum allowing gentle pull down traction of the posterior vaginal wall. Posterior vaginal wall pull down maneuver was considered as positive when a urine leak was observed during the manoeuvre. Intrinsic sphincter deficiency was urodynamically defined by maximum urethral closure pressure ≤20 cmH2 O. Correlations between positive/negative posterior vaginal wall pull down maneuver and urodynamic intrinsic sphincter deficiency were calculated. RESULTS: There was a statistical correlation between age and low maximum urethral closure pressure (P < 0.0001), and between low maximum urethral closure pressure and positive posterior vaginal wall pull down maneuver (P < 0.0001). Regarding the intrinsic sphincter deficiency diagnosis, the posterior vaginal wall pull down maneuver positive predictive value was 94.67% and the negative predictive value was 95.4%, with a specificity of 97.6% and sensitivity of 90%. CONCLUSION: Posterior vaginal wall pull down maneuver is a reliable clinical test, easy to carry out, inexpensive and without significant risk. This test allows the diagnosis of intrinsic sphincter deficiency in women suffering from stress urinary incontinence, thus avoiding further invasive urodynamic testing (urethral pressure profile, Valsalva Leak Point Pressure measurement) in women with genuine stress urinary incontinence. Furthermore, it is helpful when choosing the type of sling procedure (retropubic vs transobturator) when a surgery is planned.

Evidence for autonomic nervous system dysfunction in females with idiopathic overactive bladder syndrome.

AIMS: Micturition and continence are largely under the control of the autonomic nervous system (ANS). In this study, we analyzed ANS function using autonomic cardiovascular (CV) testing in females with idiopathic overactive bladder syndrome (iOAB) versus control females. Our hypothesis was that ANS dysfunction could comprise part of the pathophysiology of iOAB. METHODS: Twenty-three females with iOAB and 29 controls were enrolled into this prospective study. Patients performed CV autonomic testing, including two sympathetic tests (hand grip exercise and cold pressor test), two parasympathetic tests (deep breathing and 30:15 ratio), and two mixed tests (Valsalva manoeuvre and blood pressure [BP] response to standing). Patients with iOAB also underwent conventional urodynamic studies in order to define iOAB as either with or without demonstrable detrusor overactivity (DO). RESULTS: Both groups were similar with respect to age and menopausal status. Females with iOAB had significantly more positive tests than controls (P < 0.0001), particularly for sympathetic tests (P < 0.0001). Among the iOAB group, the sympathetic tests (P = 0.03) were significantly more often positive in patients without DO (based on cystometry) compared to patients with DO, with the results being particularly significant for the cold pressor test (P = 0.02). No differences were found among iOAB sufferers with respect to a past history of enuresis. CONCLUSIONS: These results suggest ANS dysfunction, predominantly a sympathetic ANS dysfunction, is associated with iOAB, specifically in patients with iOAB without DO.
