Prevalence and risk factors for pelvic floor disorders during early and late pregnancy in a cohort of Austrian women.

PURPOSE: To investigate the prevalence of pelvic floor disorders (PFDs) in a cohort of Austrian women either during their early or late pregnancy and to search for clinical risk factors which correlate with pelvic floor symptoms during pregnancy. METHODS: A prospective study was conducted and 200 pregnant women answered the validated German pelvic floor questionnaire during their first or third trimenon of gestation. Furthermore, a multivariate logistic regression model was used to determine independent risk factors for PFDs after adjusting for confounders. RESULTS: 96/200 (48%) women reported psychological strain in at least 1 of the 4 pelvic floor domains while the remaining 104 women (52%) were asymptomatic. Affected women showed a significant higher BMI, a more frequent positive family history and a higher rate of multiple pregnancies was noted compared to asymptomatic women (p < 0.05). Furthermore, a statistically significant positive correlation could be observed between BMI, smoking and mean bladder score as well as mean prolapse score, signifying more symptom bother from bladder and prolapse in smokers with high BMI. A significant positive correlation was also detected between mean bowel score and parity. In the multivariate model, high BMI (CI 1.013-1.143), positive family history (CI 0.044-0.260) and multiple pregnancies (CI 0.011-0.244) remained independently associated with pelvic floor symptoms (p < 0.05). CONCLUSION: Our results demonstrate that pelvic floor-related quality of life during pregnancy is a prevalent condition which is strongly affected by the expectant mother's weight as well as her family history. In addition, women with multiple pregnancies seem to be at increased risk.

Percutaneous tibial nerve stimulation versus tolterodine for overactive bladder in women: a randomised controlled trial.

OBJECTIVE: We performed a randomised controlled trial of percutaneous tibial nerve stimulation (PTNS) versus tolterodine for treating treatment naïve women with overactive bladder (OAB). STUDY DESIGN: 36 patients with symptoms of OAB were randomised to 3 months of treatment with weekly PTNS or tolterodine (2mg bid p.o.). The primary outcome measure was the difference of micturitions per 24h. The secondary outcome measure was the impact on quality of life (QoL) measured with a visual analogue scale (VAS) between baseline and after 3 months of therapy. RESULTS: Micturition frequencies did not decline significantly (p=0.13) over time and there were no significant treatment differences (p=0.96). QoL was significantly dependent from its level at baseline (p=0.002) and showed improvement over time compared to baseline measurements but no significant differences between both treatment groups (p=0.07). Incontinence episodes per 24h depended significantly on the level at baseline (p=0.0001) and declined significantly (p=0.03) during 3 months of therapy in both therapy groups. However no significant treatment differences on the reduction of incontinence episodes in 24h could be shown between both therapy groups (p=0.89). PTNS had fewer side effects than tolterodine (p=0.04). CONCLUSION: PTNS and tolterodine were both effective in reducing incontinence episodes and improving QoL in patients with OAB but not micturition frequencies. PTNS had fewer side effects.

Pain perception during outpatient cystoscopy: a prospective controlled study.

OBJECTIVE: Rigid cystoscopy is a common diagnostic tool in the assessment of lower urinary tract symptoms, but it is an invasive procedure which can cause distress. Data exist about pain perception during cystoscopy in male patients but only a few data are available in women. The purpose of this study was to investigate pain perception in urogynecologic patients during cystoscopy and compare it with pain perception during urodynamics. We also investigated the difference between anticipated and actual pain perception. STUDY DESIGN: A cooperative, non-randomized cohort study was performed including 109 women with pelvic floor dysfunction scheduled for outpatient cystoscopy or urodynamic testing. Patients completed a questionnaire and a visual analog scale (VAS, 0-10 cm) before and after examination. Patients were called one day after examination and asked about pain and their general state of health. According to power calculation, a sample size of 52 patients per group was needed to detect a 2 cm difference in pain scores on the VAS - judged as a clinically significant - with 95% power and a two-sided significance level of 0.05. RESULTS: In 57 patients undergoing cystoscopy versus 52 patients undergoing urodynamics, the main pain scores on VAS were 1.9 cm for cystoscopy and 1.2 cm for urodynamics (p=0.03). Patients in both groups anticipated more pain than they actually experienced: 2.7±2.4 before versus 1.9±1.8 after cystoscopy (p<0.01) and 2.1±2.4 before versus 1.2±1.6 after urodynamics (p<0.01). CONCLUSION: Patients experience cystoscopy as more painful than urodynamics. Patients anticipate both cystoscopy and urodynamics to be more painful than they actually are.

High resolution magnetic resonance imaging of urethral anatomy in continent nulliparous pregnant women.

INTRODUCTION: To quantify the distribution of morphologic appearances of urethral anatomy and measure variables of urethral sphincter anatomy in continent, nulliparous, pregnant women by high resolution magnetic resonance imaging (MRI). MATERIALS AND METHODS: We studied fifteen women during their first pregnancy. We defined and quantified bladder neck and urethral morphology on axial and sagittal MR images from healthy, continent women. RESULTS: The mean (±standard deviation) total transverse urethral diameter, anterior-posterior diameter, unilateral striated sphincter muscle thickness, and striated sphincter length were 15±2 mm (range: 12-19 mm), 15±2 mm (range: 11-20 mm), 2±1 mm (range: 1-4 mm), and 13±3 mm (range: 9-18 mm) respectively. The mean (±standard deviation) total urethral length on sagittal scans was 22±3 mm (range: 17.6-26.4 mm). DISCUSSION: Advances in MR technique combined with anatomical and histological findings will provide an insight to understand how changes in urethral anatomy might affect the continence mechanisms in pregnant and non-pregnant, continent or incontinent individuals.

Breech presentation: a retrospective analysis of 12-years' experience at a single center.

OBJECTIVE: To investigate neonatal outcome after breech presentation in term pregnancies. STUDY DESIGN: Data from 1345 term breech deliveries over a 12-year study period were retrospectively reviewed. Neonatal morbidity and mortality were compared by route of delivery. RESULTS: We investigated 1345 term breech deliveries. A total of 1041 patients (77.4%) attempted a vaginal delivery; of these, 808 (60.1%) were delivered vaginally and 233 patients (17.3%) who failed at vaginal birth underwent cesarean section. The other 304 women (22.6%) were delivered by a planned cesarean section. No statistical differences were found in the incidence of low 5-minute Apgar scores and arterial cord blood pH values

Chromosomal translocation t(10;11)(q26;q13) in a woman with combined pituitary hormone deficiency.

We describe the case of a girl with combined pituitary hormone deficiency (CPHD) carrying a balanced chromosomal translocation t(10;11)(q26;q13) with paternal transmission. Her father, with no apparent physical abnormalities, had the karyotype: 46, XY, t(10;11)(q26;q13). CPHD denotes impaired production of growth hormone (GH) and one or more of the other five anterior pituitary-derived hormones. Pit-1 gene and Prop-1 gene mutations and deletions have been reported being responsible for CPHD. Although our patient had a t(10;11) (q26q13) paternal chromosomal translocation, the phenotype was similar to that found in humans with different Pit-1 or Prop-1 gene alterations. Interestingly, the patient's father had the same translocation without phenotypic effects. In conclusion, we describe panhypopituitarism in a woman with a paternally transmitted translation, which appears to be phenotypically expressed only in females.

The urethra during pelvic floor contraction: observations on three-dimensional ultrasound.

OBJECTIVE: To investigate with three-dimensional ultrasound how voluntary pelvic floor contractions influence the morphology of the female urethra's components. METHODS: Twenty female patients with benign gynecologic disorders (mean age: 29 years; range: 19-40) had transrectal sonography using a 7.5-MHz mechanical sector endoprobe with three-dimensional features during both pelvic floor muscle relaxation and pelvic floor muscle contraction. The multiplanar display of the scanned volumes allowed detailed morphologic assessment of the urethra and the measurement of distances and volumes of the urethral components. Statistical end points were maximum sagittal and transverse urethral diameter, maximum sphincter length and thickness, maximum smooth muscle thickness, and the volumes of the sphincter, the smooth muscle, and the entire urethra. RESULTS: All 20 rectal scans were feasible. Two patients had to be excluded from analysis because of poor image quality, leaving 18 patients for evaluation. When compared with pelvic floor relaxation, the following measures were smaller during pelvic floor contraction: sagittal urethral diameter (10.4 versus 11.5 mm; P =.004), transverse urethral diameter (14.1 versus 15.0 mm; P =.009), urethral sphincter thickness (2.4 versus 2.7 mm; P =.012), urethral sphincter volume (0.5 versus 0.6 mL; P =.003), and total urethral volumes (1.4 versus 1.5 mL; P =.007). Sphincter length and smooth muscle thickness, as well as smooth muscle volume, did not change significantly during pelvic floor contraction. CONCLUSION: On three-dimensional ultrasound, the morphologic changes of the female urethra during pelvic floor contraction suggest external compression of the urethra rather than contraction of the sphincter muscle.
