Incontinence pessaries: size, POPQ measures, and successful fitting
The aim of the study was to determine whether successful incontinence pessary fitting or pessary size can be predicted by specific POPQ measurements in women without advanced pelvic organ prolapse.
In a multicenter study, women with stress urinary incontinence (SUI) and POPQ stage โค2 were randomized to three treatment arms: (1) incontinence pessary, (2) behavioral therapy, or (3) both. This study evaluates incontinence pessary size, POPQ measures, and successful fitting in the 266 women assigned to treatment arms 1 and 3.
Two hundred thirty-five women (92%) were successfully fitted with an incontinence ring (nโ=โ122) or dish (nโ=โ113). Hysterectomy, genital hiatus (GH), and GH/total vaginal length (TVL) ratios did not predict unsuccessful fitting (pโ>โ0.05). However, mean TVL was greater in women successfully fitted (9.6 vs. 8.8ย cm, pโ<โ0.01). Final pessary diameter was not predicted by TVL, point D, or point C (pโ>โ0.05).
The vast majority of women with SUI can be successfully fitted with an incontinence pessary, but specific POPQ measures were not helpful in determining incontinence pessary size
Risk factors for mesh/suture erosion following sacral colpopexy
To identify risks for mesh/suture erosions following sacrocolpopexy (ASC)
Prevalence and risk factors for mesh erosion after laparoscopic-assisted sacrocolpopexy
The purpose of this study is to identify risk factors for mesh erosion in women undergoing minimally invasive sacrocolpopexy (MISC). We hypothesize that erosion is higher in subjects undergoing concomitant hysterectomy.
This is a retrospective cohort study of women who underwent MISC between November 2004 and January 2009. Demographics, operative techniques, and outcomes were abstracted from medical records. Multivariable regression identified odds of erosion.
Of 188 MISC procedures 19(10%) had erosions. Erosion was higher in those with total vaginal hysterectomy (TVH) compared to both post-hysterectomy (23% vs. 5%, pโ=โ0.003) and supracervical hysterectomy (SCH) (23% vs. 5%, pโ=โ0.109) groups. In multivariable regression, the odds of erosion for TVH was 5.67 (95% CI: 1.88โ17.10) compared to post-hysterectomy. Smoking, the use of collagen-coated mesh, transvaginal dissection, and mesh attachment transvaginally were no longer significant in the multivariable regression model.
Based on this study, surgeons should consider supracervical hysterectomy over total vaginal hysterectomy as the procedure of choice in association with MISC unless removal of the cervix is otherwise indicated

Committee Opinion No.703: Asymptomatic Microscopic Hematuria in Women.
Asymptomatic microscopic hematuria is an important clinical sign of urinary tract malignancy. Asymptomatic microscopic hematuria has been variably defined over the years. In addition, the evidence primarily is based on data from male patients. However, whether the patient is a man or a woman influences the differential diagnosis of asymptomatic microscopic hematuria, and the risk of urinary tract malignancy (bladder, ureter, and kidney) is significantly less in women than in men. Among women, being older than 60 years, having a history of smoking, and having gross hematuria are the strongest predictors of urologic cancer. In low-risk, never-smoking women younger than 50 years without gross hematuria and with fewer than 25 red blood cells per high-power field, the risk of urinary tract malignancy is less than or equal to 0.5%. Furthermore, the evaluation may result in more harm than benefit and is unlikely to be cost effective. Thus, data support changing current hematuria recommendations in this low-risk group. The American College of Obstetricians and Gynecologists and the American Urogynecologic Society encourage organizations producing future guidelines on the evaluation of microscopic hematuria to perform sex-specific analysis of the data and produce practical sex-specific recommendations. In the meantime, the American College of Obstetricians and Gynecologists and the American Urogynecologic Society recommend that asymptomatic, low-risk, never-smoking women aged 35-50 years undergo evaluation only if they have more than 25 red blood cells per high-power field
Urethral sleeve sensor: a non-withdrawal method to measure maximum urethral pressure
This study seeks to evaluate axial variation, comparisons with current technology, performance during dynamic conditions, and patient tolerability of the urethral sleeve sensor (USS) for maximal urethral closure pressure (MUCP) measurements.
Eighteen continent and seven stress incontinent women underwent assessments with USS and urethral pressure profilometry (UPP) in random order. Intravesical (p
ves) and urethral (p
ura) pressure signals were collected and urethral closure pressure (p
clo) was calculated. A visual analog scale (VAS) was used to evaluate subject discomfort.
The correlation coefficient between MUCP obtained by UPP and USS techniques was 0.86 (pโ<โ0.001). Higher USS pressures were obtained with catheter oriented to 12 oโclock. Continent subjects demonstrated higher values of p
clo. MUCP became <0ย cm H2O in subjects with clinical leakage during Valsalva, but not in continent subjects. Subjects tolerated the USS technique better than the UPP technique on VAS (pโ<โ0.001).
USS technology can be used to evaluate the urethra in both static and dynamic conditions and is better tolerated than withdrawal techniques

A comparative study of water perfusion catheters and microtip transducer catheters for urethral pressure measurements
The aim of this study was to compare the maximum urethral closure pressure (MUCP) measures with two different techniques: water perfused catheter and microtip transducer catheters with respect to reproducibility and comparability for urethral pressure measurements. Eighteen women with stress urinary incontinence had repeat static urethral pressure profilometry on a different day using a dual microtip transducer and water perfused catheter (Brown and Wickham). The investigators were blinded to the results of the other. The microtip measurements were taken in the 45 degrees upright sitting position with the patient at rest at a bladder capacity of 250 ml using an 8 Fr Gaeltec(R) double microtip transducer withdrawn at 1 mm/s, and the transducer was orientated in the three o'clock position. Three different measures were taken for each patient. Three water perfusion measurements were performed with the patient at rest in the 45 degrees upright position at a bladder capacity of 250 ml using an 8 Fr BARD dual lumen catheter withdrawn at 1 mm/s. The mean water perfusion MUCP measure was 26.1 cm H(2)0, significantly lower than the mean microtip measure of 35.7 cm H(2)0. The correlation coefficient comparing each water perfusion measurement with the other water perfusion measures in the same patient was excellent, at 0.95 (p = 0.01). Correlation coefficient comparing each microtip measure with the other microtip measure in the same patient was also good, ranging from 0.70 to 0.80. This study confirms that both water perfusion catheters and microtip transducers have excellent or very good reproducibility with an acceptable intraindividual variation for both methods
The female continence mechanism measured by high resolution manometry: Urethral bulking versus midurethral sling.
AIMS:Traditional technology to characterize urethral pressure changes during dynamic conditions is limited by slow response times or artifact-inducing withdrawal maneuvers. The 8F high-resolution manometry (HRM) catheter (ManoScanโข ESO, Covidien) has advantages of fast response times and the ability to measure urethral pressures along the urethral length without withdrawal. Our objective was to determine static and dynamic maximum urethral closure pressures (MUCPs) and resting functional urethral length (FUL) in women using HRM before and after transurethral bulking and compare results to other women who underwent midurethral sling (MUS). METHODS:We recorded rest, cough, and strain MUCPs and FUL in 24 women before and after transurethral bulking with polydimethylsiloxane (Macroplastiqueยฎ) using the HRM catheter and compared these changes to HRM values from 26 women who had the same measures before and after MUS. RESULTS:At rest, MUCPs increased minimally after both urethral bulking and MUS (3 vs 0.4โcm H2 O respectively, Pโ=โ0.4). Under dynamic conditions there were statistically insignificant small increases in MUCP and these increases were markedly less than after MUS (cough: 1.5 vs 63.8โcm H2 O, Pโ<โ0.001 and strain: 11.5 vs 57.7โcm H2 O, Pโ<โ0.001). FUL increased by 0.5โcm after transurethral bulking (Pโ=โ0.003), and decreased by 0.25โcm after MUS placement (Pโ=โ0.012). CONCLUSIONS:The mechanism of continence after urethral bulking differs from MUS. While MUS increases dynamic MUCP, bulking may rely on increasing the length of the continence zone
