Female bladder neck dysfunction-A video-urodynamic diagnosis among women with voiding dysfunction.

OBJECTIVE: To investigate bladder neck dysfunction (BND) in women with voiding dysfunction by video-urodynamic study (VUDS) and to examine the therapeutic results of different BND subtypes. MATERIALS AND METHODS: We retrospectively reviewed consecutive women who had undergone VUDS for investigation of voiding dysfunction at our institution. The diagnosis of BND was made based on a nonfunneling bladder neck with or without high voiding detrusor pressure. Patients diagnosed as BND were retrieved, and the urodynamic parameters were compared with patients with dysfunctional voiding (DV) and other bladder outlet obstructions (BOO). RESULTS: Among 810 women with bladder outlet dysfunction, BND was noted in 100 (12.3%), poor pelvic floor relaxation in 336 (41.5%), DV in 325 (40.1%), cystocele in 19 (2%), and urethral stricture in 30 (4%). Compared with the normal tracing group, BND patients had a significantly smaller volume of bladder filling sensation (included first sensation of filling, full sensation and cystometric bladder capaicity) and a greater BOO index (BOOI) (all P < .05). Detrusor overactivity was noted in 46 (46%) BND patients. These urodynamic parameters in BND were not significantly different from patients with DV or other BOO. High-pressure BND had a greater BOOI, but low-pressure BND had a lower voiding efficiency. Both alpha-blocker therapy and transurethral incision of the bladder neck improved uroflow parameters in BND patients. CONCLUSIONS: BND includes 12.3% of women with bladder outlet dysfunction. High-pressure BND can cause anatomical BOO, whereas low-pressure BND is likely to affect micturition through inhibiting detrusor contractility. VUDS is the mainstay diagnostic tool to diagnose BND in women.

Transperineal Ultrasound Assessment of a Cystocele's Impact on the Bladder Neck Mobility in Women with Stress Urinary Incontinence.

Background and objectives: As pelvic floor disorders are often difficult to assess thoroughly based on clinical examination alone, the use of imaging as a complementary technique is helpful. This study's aim was to investigate by transperineal ultrasound (US) if there was any significant difference in the mobility of the bladder neck in women with stress urinary incontinence (SUI) without a cystocele and in those with SUI and an associated cystocele. The study also investigated whether the number of vaginal births and/or the heaviest newborn's birth weight was correlated with the bladder neck mobility. Materials and Methods: A total of 71 women suffering from SUI were included in the study and divided into two groups based on the presence of a cystocele. Their bladder neck mobility was evaluated by transperineal US, calculating the distance from the inferior margin of the symphysis pubis to the bladder neck (SPBN), and the dorsocaudal linear movement (DLM), term used to illustrate the displacement of the bladder neck by subtracting rest and Valsalva values. GraphPad Prism 8 was used for statistical analysis. Results: Within both study groups, the SPBN values were significantly higher and the DLM values were significantly lower at rest as compared to Valsalva maneuver (p < 0.05). No significant difference between the groups regarding SPBN and DLM values at rest, Valsalva, or subtraction was demonstrated. A significant positive correlation was found between the bladder neck mobility and the heaviest newborn's birth weight, regardless of the presence of a cystocele (p = 0.042). Conclusions: The presence of a cystocele had no significant impact on the bladder neck mobility measurements in patients with SUI. The heaviest newborn's birth weight positively correlated with bladder neck hypermobility, as quantified by SPBN.

Structural, functional, and symptomatic differences between women with rectocele versus cystocele and normal support.

BACKGROUND: Prolapse of the anterior and posterior vaginal walls has been generally associated with apical descent and levator ani muscle defects. However, the relative contributions of these factors to the pathophysiology of descent in the different vaginal compartments is not well understood. Furthermore, symptoms uniquely associated with prolapse in these compartments have not been well characterized. OBJECTIVES: The objectives of the study were to compare the associations between the following: (1) apical support, (2) levator ani muscles, and (3) pelvic floor symptoms in women with posterior-predominant prolapse, anterior-predominant prolapse, and normal support. STUDY DESIGN: This is a cross-sectional study with 2 case arms: 60 women with posterior prolapse, 90 with anterior prolapse, and a referent control arm with 103 asymptomatic subjects with normal support, determined from pelvic organ prolapse quantification examinations. Levator muscle defects were graded from magnetic resonance imaging. Vaginal closure forces above resting were measured with an instrumented speculum during maximal contraction. Pelvic floor symptoms were measured via the Pelvic Floor Distress Inventory-Short Form. RESULTS: Mean point C location in controls was -6.9 cm [1.5] (mean [standard deviation]); and was higher in posterior prolapse (-4.7 cm [2.7], 2.2 cm below controls) than the anterior prolapse group (-1.2 cm [4.1]; 5.6 cm below controls, P < .001 for all comparisons). Normal-appearing muscles (ie, muscle without a visible defect) occurred at similar frequencies in posterior prolapse (45%) and controls (51%, P = .43) but less often in anterior prolapse (28%, P ≤ .03 for pairwise comparisons). Major levator ani defects occurred at similar rates in women with posterior (33%) and anterior prolapse (42%, P = .27) but less often in controls (16%, P ≤ .012 for both pairwise comparisons). Similarly, there were significant differences in generated vaginal closure forces across the 3 groups, with the prolapse groups generating weaker closure forces than the control group (P = .004), but the differences between the 2 prolapse groups were not significant after controlling for prolapse size (P = .43). Pelvic floor symptoms were more severe for the posterior (mean Pelvic Floor Distress Inventory score, 129) and anterior prolapse groups (score, 128) than the controls (score, 40.2, P < .001 for both comparisons); the difference between the 2 prolapse groups was not significant (P = .83). CONCLUSION: Posterior-predominant prolapse involves an almost 3-fold less apical descent below normal than anterior-predominant vaginal prolapse. Levator ani defects and muscle impairment also have a lower impact. Pelvic floor symptoms reflect the presence and size of prolapse more than the predominant lax vaginal compartment.

Safety of Vaginal Mesh Surgery Versus Laparoscopic Mesh Sacropexy for Cystocele Repair: Results of the Prosthetic Pelvic Floor Repair Randomized Controlled Trial.

BACKGROUND: Laparoscopic mesh sacropexy (LS) or transvaginal mesh repair (TVM) are surgical techniques used to treat cystoceles. Health authorities have highlighted the need for comparative studies to evaluate the safety of surgeries with meshes. OBJECTIVE: To compare the rate of complications, and functional and anatomical outcomes between LS and TVM. DESIGN, SETTING, AND PARTICIPANTS: Multicenter randomized controlled trial from October 2012 to April 2014 in 11 French public hospitals. Women with cystocele stage ≥2 (pelvic organ prolapse quantification), aged 45-75 yr, without previous prolapse surgery. INTERVENTION: Synthetic nonabsorbable mesh placed in the vesicovaginal space, sutured to the promontory (LS) or maintained by arms through pelvic ligaments (TVM). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Rate of surgical complications ≥grade II according to the modified Clavien-Dindo classification at 1 yr. Secondary outcomes were reintervention rate, and functional and anatomical results. RESULTS AND LIMITATIONS: A total of 130 women were randomized in LS and 132 in TVM; five women withdrew before intervention, leaving 129 in LS and 128 in TVM. The rate of complications ≥grade II was lower after LS than after TVM, but did not meet statistical significance (17% vs 26%, treatment difference 8.6% [95% confidence interval, CI -1.5 to 18]; p=0.088). The rate of complications of grade III or higher was nonetheless significantly lower after LS (LS=0.8%, TVM=9.4%, treatment difference 8.6% [95% CI 3.4%; 15%]; p=0.001). LS was converted to TVM in 6.3%. The total reoperation rate was lower after LS but did not meet statistical significance (LS=4.7%, TVM=10.9%, treatment difference 6.3% [95% CI -0.4 to 13.3]; p=0.060). There was no difference in symptoms, quality of life, improvement, composite definition of success, anatomical results rates between groups except for the vaginal apex and length, and dyspareunia (in favor of LS). CONCLUSIONS: LS is a valuable option for primary repair of cystocele in sexually active patients. LS is safer than TVM, but may not be feasible in all cases. Both techniques offer same functional outcomes, success rates, and anatomical outcomes, but sexual function is better preserved by LS. PATIENT SUMMARY: Our study demonstrates that laparoscopic sacropexy (LS) is a valuable option for primary repair of cystocele. LS offers equivalent success rates to vaginal mesh procedures, but is safer with a lower rate of complications and reoperations, and sexual function is better preserved.

Effect of Cystocele Repair on Cervix Location in Women With Uterus In Situ.

INTRODUCTION AND HYPOTHESIS: Our objective was to test the hypothesis that cystocele repair, in the absence of hysterectomy or apical suspension, results in higher cervix location in some women. METHODS: We performed a retrospective chart review of women with a uterus in situ who underwent native tissue anterior repair without hysterectomy/apical suspension from 2008 to 2014. Demographics, medical history, and preoperative and 6-week postoperative Pelvic Organ Prolapse Quantification System measurements were abstracted. Cervix location was defined by the clinic Pelvic Organ Prolapse Quantification System point C value. Women with higher (more negative) postoperative point C values were compared with those with a lower (more positive)/unchanged point C. RESULTS: Of the 33 women included, mean age was 59.8 ± 11.3 years. Median preoperative point C was -6.0 (interquartile range [IQR]: -6.75, -5.0) and point Ba was +2.0 (IQR: +0.5, +3.0). Point C was higher postoperatively in 21 (64%) of 33 women. Overall, point C was 1 cm higher post- versus preoperatively (-7.0 [IQR: -8.0, -6.0] vs -6.0 [IQR: -6.75, -5.0], P < 0.001) and point Ba was 4 cm higher (-2 [IQR: -3.0, -2.0] vs 2.0 [IQR: 0.5, 3.0], P < 0.001). Compared with women with lower/unchanged postoperative point C, those with higher point C were older (53.9 ± 12.3 vs 63.1 ± 9.4, P = 0.02) with lower parity (3.0 [IQR: 2.0, 3.0] vs 2.0 [IQR: 2.0, 3.0], P = 0.028). CONCLUSIONS: The test of our hypothesis shows that in certain women with cystocele, anterior repair alone may be associated with higher cervix location 6 weeks postoperatively.

Intraoperative cervix location and apical support stiffness in women with and without pelvic organ prolapse.

BACKGROUND: It is unknown how initial cervix location and cervical support resistance to traction, which we term "apical support stiffness," compare in women with different patterns of pelvic organ support. Defining a normal range of apical support stiffness is important to better understand the pathophysiology of apical support loss. OBJECTIVE: The aims of our study were to determine whether: (1) women with normal apical support on clinic Pelvic Organ Prolapse Quantification, but with vaginal wall prolapse (cystocele and/or rectocele), have the same intraoperative cervix location and apical support stiffness as women with normal pelvic support; and (2) all women with apical prolapse have abnormal intraoperative cervix location and apical support stiffness. A third objective was to identify clinical and biomechanical factors independently associated with clinic Pelvic Organ Prolapse Quantification point C. STUDY DESIGN: We conducted an observational study of women with a full spectrum of pelvic organ support scheduled to undergo gynecologic surgery. All women underwent a preoperative clinic examination, including Pelvic Organ Prolapse Quantification. Cervix starting location and the resistance (stiffness) of its supports to being moved steadily in the direction of a traction force that increased from 0-18 N was measured intraoperatively using a computer-controlled servoactuator device. Women were divided into 3 groups for analysis according to their pelvic support as classified using the clinic Pelvic Organ Prolapse Quantification: (1) "normal/normal" was women with normal apical (C < -5 cm) and vaginal (Ba and Bp < 0 cm) support; (2) normal/prolapse had normal apical support (C < -5 cm) but prolapse of the anterior or posterior vaginal walls (Ba and/or Bp ≥ 0 cm); and (3) prolapse/prolapse had both apical and vaginal wall prolapse (C > -5 cm and Ba and/or Bp ≥ 0 cm). Demographics, intraoperative cervix locations, and apical support stiffness values were then compared. Normal range of cervix location during clinic examination and operative testing was defined by the total range of values observed in the normal/normal group. The proportion of women in each group with cervix locations within and outside the normal range was determined. Linear regression was performed to identify variables independently associated with clinic Pelvic Organ Prolapse Quantification point C. RESULTS: In all, 52 women were included: 14 in the normal/normal group, 11 in the normal/prolapse group, and 27 in the prolapse/prolapse group. At 1 N of traction force in the operating room, 50% of women in the normal/prolapse group had cervix locations outside the normal range while 10% had apical support stiffness outside the normal range. Of women in the prolapse/prolapse group, 81% had cervix locations outside the normal range and 8% had apical support stiffness outside the normal range. Similar results for cervix locations were observed at 18 N of traction force; however the proportion of women with apical support stiffness outside the normal range increased to 50% in the normal/prolapse group and 59% in the prolapse/prolapse group. The prolapse/prolapse group had statistically lower apical support stiffness compared to the normal/normal group with increased traction from 1-18 N (0.47 ± 0.18 N/mm vs 0.63 ± 0.20 N/mm, P = .006), but all other comparisons were nonsignificant. After controlling for age, parity, body mass index, and apical support stiffness, cervix location at 1 N traction force remained an independent predictor of clinic Pelvic Organ Prolapse Quantification point C, but only in the prolapse/prolapse group. CONCLUSION: Approximately 50% of women with cystocele and/or rectocele but normal apical support in the clinic had cervix locations outside the normal range under intraoperative traction, while 19% of women with uterine prolapse had normal apical support. Identifying women whose apical support falls outside a defined normal range may be a more accurate way to identify those who truly need a hysterectomy and/or an apical support procedure and to spare those who do not.

Pathophysiological aspects of cystocele with a 3D finite elements model.

PURPOSES: The objective of this study is to design a 3D biomechanical model of the female pelvic system to assess pelvic organ suspension theories and understand cystocele mechanisms. METHODS: A finite elements (FE) model was constructed to calculate the impact of suspension structure geometry on cystocele. The sample was a geometric model of a control patient's pelvic organs. The method used geometric reconstruction, implemented by the biomechanical properties of each anatomic structure. Various geometric configurations were simulated on the FE method to analyse the role of each structure and compare the two main anatomic theories. RESULTS: The main outcome measure was a 3D biomechanical model of the female pelvic system. The various configurations of bladder displacement simulated mechanisms underlying medial, lateral and apical cystocele. FE simulation revealed that pubocervical fascia is the most influential structure in the onset of median cystocele (essentially after 40 % impairment). Lateral cystocele showed a stronger influence of arcus tendineus fasciae pelvis (ATFP) on vaginal wall displacement under short ATFP lengthening. In apical cystocele, the uterosacral ligament showed greater influence than the cardinal ligament. Suspension system elongation increased displacement by 25 % in each type of cystocele. CONCLUSIONS: A 3D digital model enabled simulations of anatomic structures underlying cystocele to better understand cystocele pathophysiology. The model could be used to predict cystocele surgery results and personalising technique by preoperative simulation.

A biofidelic computational model of the female pelvic system to understand effect of bladder fill and progressive vaginal tissue stiffening due to prolapse on anterior vaginal wall.

Treatment of anterior vaginal prolapse (AVP), suffered by over 500,000 women in the USA, is a challenge in urogynecology because of the poorly understood mechanics of AVP. Recently, computational modeling combined with finite element method has been used to model AVP through the study of pelvic floor muscle and connective tissue impairments on the anterior vaginal wall (AVW). Also, the effects of pelvic organ displacements on the AVW were studied numerically. In our current work, an MRI-based full-scale biofidelic computational model of the female pelvic system composed of the urinary bladder, vaginal canal, and the uterus was developed, and a novel finite element method framework was employed to simulate vaginal tissue stiffening and also bladder filling due to expansion for the first time. A mesh convergence study was conducted to choose a computationally efficient mesh, and a non-linear hyperelastic Yeoh's material model was adopted for the study. The AVW displacements, mechanical stresses, and strains were estimated at varying degrees of bladder fills and vaginal tissue stiffening. Both bladder filling and vaginal stiffening were found to increase the stress concentration on the AVW with varying trends, which have been discussed in detail in the paper. To our knowledge, this study is the first to estimate the individual and combined effects of bladder filling and vaginal tissue stiffening due to prolapse on the AVW.

Cystocele and functional anatomy of the pelvic floor: review and update of the various theories.

INTRODUCTION AND HYPOTHESIS: We updated anatomic theories of pelvic organ support to determine pathophysiology in various forms of cystocele. METHODS: PubMed/MEDLINE, ScienceDirect, Cochrane Library, and Web of Science databases were searched using the terms pelvic floor, cystocele, anatomy, connective tissue, endopelvic fascia, and pelvic mobility. We retrieved 612 articles, of which 61 matched our topic and thus were selected. Anatomic structures of bladder support and their roles in cystocele onset were determined on the international anatomic classification; the various anatomic theories of pelvic organ support were reviewed and a synthesis was made of theories of cystocele pathophysiology. RESULTS: Anterior vaginal support structures comprise pubocervical fascia, tendinous arcs, endopelvic fascia, and levator ani muscle. DeLancey's theory was based on anatomic models and, later, magnetic resonance imaging (MRI), establishing a three-level anatomopathologic definition of prolapse. Petros's integral theory demonstrated interdependence between pelvic organ support systems, linking ligament-fascia lesions, and clinical expression. Apical cystocele is induced by failure of the pubocervical fascia and insertion of its cervical ring; lower cystocele is induced by pubocervical fascia (medial cystocele) or endopelvic fascia failure at its arcus tendineus fasciae pelvis attachment (lateral cystocele). CONCLUSIONS: Improved anatomic knowledge of vaginal wall support mechanisms will improve understanding of cystocele pathophysiology, diagnosis of the various types, and surgical techniques. The two most relevant theories, DeLancey's and Petros's, are complementary, enriching knowledge of pelvic functional anatomy, but differ in mechanism. Three-dimensional digital models could integrate and assess the mechanical properties of each anatomic structure.

Assessment of perioperative, early, and late postoperative complications of the inside-out transobturator tape procedure in the treatment of stress urinary incontinence..

OBJECTIVE: To evaluate the complications of urinary incontinence surgery with transobturator tape (TVT-O) system and to describe its diagnosis and management. MATERIALS AND METHODS: A total of 156 patients who were diagnosed as having stress incontinence and mixed incontinence with stress predominance underwent a TOT operation under spinal anesthesia by one surgeon or two surgeons (MB, AEY) from the team. TVT-obturator inside out material was used in the operation. Urodynamic tests and pad tests were done on all the patients. This is a prospective and retrospective study of the complications of TVT-O. The operation was performed under regional anesthesia, as described by Deval et al. Patients were excluded from the study if they had been operated under general or local anesthesia, had undergone any vaginal operations except for anterior repair (cystocele), wanted to have a baby, had severe systemic diseases or had been diagnosed as having urge incontinence in urodynamic tests. These situations may affect the rate of complications, the authors also excluded slings that had materials other than monofilament polypropylene, and patients who were suspected of having neurologic bladder conditions. The bladder and urethra were evaluated using cystoscopy. The durations of the TOT procedure, cystoscopy, and if performed, the cystocele operation, were recorded. Perioperative, early, and late postoperative complications were analyzed by follow-up visits (after two months to four years). RESULTS: Of the 156 patients included in the study, 100 (64.1%) had pure stress urinary incontinence and 56 (35.9%) had mixed incontinence, 20 (12.8%) had previous incontinence surgery. The mean duration of follow up was 30.3 ± 7.4 (range 17-42) months. The mean age of the patients was found to be 48.43 ± 6.24 years (range 42-68). The mean parity of the patients was 5.24 ± 2.86 (range 2-13), and mean body mass index was found to be 23.7 ± 4.8. Mean maximum detrusor pressure was 10.30 ± 4.08 and the mean ALP value was 80.80 ± 25.57. Mean operative time was found to be 13.8 ± 5.16 min in patients who underwent only TOT and TOT-anterior repair. Vaginal injury including to the lateral fornix (4.4%), hemorrhaging of more than 200 ml (3.2%), vascular damage (1.9%), hematoma on the leg (1.9%), hemorrhaging of more than 500 ml (0.064%), and bladder perforation (1.2%) were detected as perioperative complications. Urethral injury and perioperative nerve and intestinal injury did not occur. The most common complication in early postoperative period was inguinal pain extending the legs (30.7%), followed by headaches (23.7%), fever (12.8%), urinary tract infection (5.7%), and urinary retention (3.2%), respectively. Late postoperative complications included vaginal erosion (4.4%), de novo urge incontinence (8.9%), de novo dyspareunia (7.1%), perineal pain (4.4%), and worsening urgency (8.9%). CONCLUSION: Although the TVT-O technique is a minimal invasive surgery method applied to treat the urinary incontinence surgically, it does not imply that it is a complication-free surgical procedure. Despite the low incidence of intraoperative complications, there is a mild risk of early and late postoperative complications. Fortunately these complications can be taken under control by either conservative and simple medical treatments or surgical procedures.

A multi-compartment 3-D finite element model of rectocele and its interaction with cystocele.

We developed a subject-specific 3-D finite element model to understand the mechanics underlying formation of female pelvic organ prolapse, specifically a rectocele and its interaction with a cystocele. The model was created from MRI 3-D geometry of a healthy 45 year-old multiparous woman. It included anterior and posterior vaginal walls, levator ani muscle, cardinal and uterosacral ligaments, anterior and posterior arcus tendineus fascia pelvis, arcus tendineus levator ani, perineal body, perineal membrane and anal sphincter. Material properties were mostly from the literature. Tissue impairment was modeled as decreased tissue stiffness based on previous clinical studies. Model equations were solved using Abaqus v 6.11. The sensitivity of anterior and posterior vaginal wall geometry was calculated for different combinations tissue impairments under increasing intraabdominal pressure. Prolapse size was reported as pelvic organ prolapse quantification system (POP-Q) point at point Bp for rectocele and point Ba for cystocele. Results show that a rectocele resulted from impairments of the levator ani and posterior compartment support. For 20% levator and 85% posterior support impairments, simulated rectocele size (at POP-Q point: Bp) increased 0.29 mm/cm H2O without apical impairment and 0.36 mm/cm H2O with 60% apical impairment, as intraabdominal pressures increased from 0 to 150 cm H2O. Apical support impairment could result in the development of either a cystocele or rectocele. Simulated repair of posterior compartment support decreased rectocele but increased a preexisting cystocele. We conclude that development of rectocele and cystocele depend on the presence of anterior, posterior, levator and/or or apical support impairments, as well as the interaction of the prolapse with the opposing compartment.

Large rectovaginal fistula due to a cube pessary despite routine follow-up; but what is 'routine'?

Vaginal pessaries are generally considered a safe and effective form of management for pelvic organ prolapse. Serious complications such as rectovaginal fistula can develop with or without regular follow-up. This case report describes the rapid development over a 10-week period of a large rectovaginal fistula in a 75-year-old woman, despite routine follow-up and replacement of her cube pessary. Currently, there is a lack of evidence-based guidelines for pessary care and, in particular, the frequency of pessary replacement. Intervals for pessary replacements vary greatly and are often based on the manufacturer's recommendations. This case highlights the rapidity at which serious complications can develop and also represents the first reported case of a cube pessary-induced rectovaginal fistula.

Pelvic organ prolapse in a cohort of women treated for stress urinary incontinence.

OBJECTIVE: The aim of our study was to observe pelvic organ prolapse (POP) over time, treated and untreated, in a group of highly characterized women being followed up subjectively and objectively over 5-7 years following continence surgery. STUDY DESIGN: We measured baseline prolapse symptoms and anatomic prolapse in subjects enrolled in the trial of midurethral sling (TOMUS) and E-TOMUS, and measured these same parameters annually for 5-7 years after the index surgery. Additional information about subsequent treatment for POP was also recorded. RESULTS: In all, 597 women were randomized to 1 of 2 midurethral sling procedures in the TOMUS; concomitant vaginal procedures for POP were allowed at the surgeon's discretion. Stage 2 POP was present at baseline in 291 subjects (49%). Symptoms of POP were reported in 67 (25%). Of the asymptomatic women, 34 of 223 (15%) underwent a concomitant POP repair at the time of index sling surgery. Anatomic progression of prolapse in women with asymptomatic, unoperated stage 2 POP over the next 72 months was infrequent and occurred in only 3 of 189 subjects (2%); none underwent surgery for POP. Most symptomatic women (47/67 [70%]) underwent a concomitant repair for POP at the index sling surgery. Three of the 47 women who had undergone concomitant repair for symptomatic stage 2 POP underwent repeat POP surgery (2 at 36 months and 1 at 48 months.) CONCLUSION: For patient populations similar to the TOMUS and E-TOMUS populations, surgeons may counsel women with asymptomatic stage 2 POP that their prolapse is unlikely to require surgery in the next 5-7 years.

The length of anterior vaginal wall exposed to external pressure on maximal straining MRI: relationship to urogenital hiatus diameter, and apical and bladder location.

INTRODUCTION AND HYPOTHESIS: In cystoceles, the distal anterior vaginal wall (AVW) bulges out through the introitus and is no longer in contact with the posterior vaginal wall or perineal body, exposing the pressure differential between intra-abdominal pressure and atmospheric pressure. The goal of this study is to quantify the length of the exposed vaginal wall length and to investigate its relationship with other factors associated with the AVW support, such as most dependent bladder location, apical location, and hiatus diameter, demonstrating its key role in cystocele formation. METHODS: Fifty women were selected to represent a full spectrum of AVW support. Each underwent supine, dynamic MR imaging. Most dependent bladder location and apical location were measured relative to the average normal position on the mid-sagittal plane using the Pelvic Inclination Correction System . The length of the exposed AVW and the hiatus diameter were measured as well. The relationship between exposed AVW and most dependent bladder location, apical location, and hiatus diameter were examined. RESULTS: A bilinear relationship has been observed between exposed vaginal wall length and most dependent bladder location (R(2) = 0.91, P < 0.001). When the bladder descents up to the inflection point (about 4.4 cm away from its normal position), there is little change in the exposed AVW length. With further descent, the exposed vaginal wall length increases significantly, with a 2 cm increase in exposed AVW length for every additional 1 cm of drop bladder location. A similar but weaker bilinear relationship exists between exposed AVW and apical location. Exposed vaginal wall length is also highly correlated with hiatus diameter (R(2) = 0.85, P < 0.001). CONCLUSION: A bilinear relationship exists between exposed vaginal wall length and most dependent bladder location and apical location. It is when the bladder descent is beyond the inflection point that exposed vaginal wall length increases significantly.

Relationship between intra-abdominal pressure and vaginal wall movements during Valsalva in women with and without pelvic organ prolapse: technique development and early observations.

OBJECTIVES: To develop and test a method for measuring the relationship between the rise in intra-abdominal pressure and sagittal plane movements of the anterior and posterior vaginal walls during Valsalva in a pilot sample of women with and without prolapse. METHODS: Mid-sagittal MRI images were obtained during Valsalva while changes in intra-abdominal pressure were measured via a bladder catheter in 5 women with cystocele, 5 women with rectocele, and 5 controls. The regional compliance of the anterior and posterior vagina wall support systems were estimated from the ratio of displacement (mm) of equidistant points along the anterior and posterior vaginal walls to intra-abdominal pressure rise (mmHg). RESULTS: The compliance of both anterior and posterior vaginal wall support systems varied along different regions of vaginal wall for all three groups, with the highest compliance found near the vaginal apex and the lowest near the introitus. Women with cystocele had more compliant anterior and posterior vaginal wall support systems than women with rectocele. The movement direction differs between cystocele and rectocele. In cystocele, the anterior vaginal wall moves mostly toward the vaginal orifice in the upper vagina, but in a ventral direction in the lower vagina. In rectocele, the direction of the posterior vaginal wall movement is generally toward the vaginal orifice. CONCLUSIONS: Movement of the vaginal wall and compliance of its support is quantifiable and was found to vary along the length of the vagina. Compliance was greatest in the upper vagina of all groups. Women with cystocele demonstrated the most compliant vaginal wall support.

Points Aa and Ba are factors associated with preoperative voiding dysfunction in patients with cystocele.

OBJECTIVE: It has been hypothesized that women with significant pelvic organ prolapse (POP), particularly of the anterior vaginal wall, may have voiding dysfunction (VD). Rarely, different compartments of the vagina have been examined closely for VD. This study attempts to further elucidate the correlation between POP and VD by using the standardized Pelvic Organ Prolapse Quantification (POP-Q) staging system. STUDY DESIGN: The clinical records of 66 women who underwent cystocele (≥POP-Q stage III) repair with concomitant midurethral sling were reviewed. Urodynamic study and POP-Q examination were performed preoperatively. The subjects were divided into two groups according to the presence of VD, which was defined as the presence of at least one of the following criteria: maximal flow rate below 15mL/s or postvoid residual urine volume (PVR) above 50mL on preoperative uroflowmetry. Age, parity, uroflowmetry and urodynamic parameters were compared between the two groups. RESULTS: Of 66 women, 36 had VD preoperatively. In the VD group, failure in the postoperative voiding trial was more frequent (p=0.040), with lower maximal flow rate (p=0.007) and higher PVR (p=0.034). POP-Q stage was significantly higher (p=0.018), and points Aa and Ba were significantly longer (p=0.005 and p=0.006, respectively) in the VD group. POP-Q stage with points Aa and Ba were significantly correlated with the presence of preoperative VD, and moderately correlated with PVR. CONCLUSION: The prevalence of VD in patients with cystocele is high (55%). Points Aa and Ba of POP-Q stage had positive correlations with VD in patients with cystocele.

Unusual videourodynamic finding: massive scrotal cystocele.

Urinary bladder involvement within inguinal hernias occurs in up to 4% of patients. However, massive extension of the bladder into the scrotum, or scrotal cystocele, is very rare, with less than 30 reported cases. The presenting symptoms vary. Most patients will have some element of voiding dysfunction. However, some patients will present with renal failure, sepsis, or bladder necrosis, although others will remain asymptomatic.(1-4) We report a patient who presented with irritative voiding symptoms and a large, right-sided hydrocele. On evaluation of his voiding symptoms, he was found to have a large scrotal cystocele.

Encephalocystocele - uncommon diagnosis in prenatal medicine.

Encephalocystocele is a developmental malformation characterized by brain herniation accompanied with extracranial cystic protrusion of the ventricular system. This nosological unit is often overlooked and insufficiently classified merely as encephalocele. Herein, two exceptionally clear cases of the parieto-occipital cranioschisis with encephalocystocele and congenital hydrocephalus of the lateral ventricles are documented with 2-dimensional/3-dimensional sonographic images and the corresponding MRI findings. In both cases, prenatal diagnosis was confirmed by autopsy.

Prevalence of and risk factors for pelvic organ prolapse and lower urinary tract symptoms among women in rural Nepal.

OBJECTIVE: To evaluate the prevalence and associated risk factors of pelvic organ prolapse (POP) and lower urinary tract symptoms (LUTS) among women seeking healthcare services in 3 discrete rural areas in Nepal. METHODS: A cross-sectional study was conducted using a Nepalese-specific questionnaire to obtain demographic and personal information. Urinary symptoms were examined using the Urogenital Distress Inventory Short form questionnaire, while POP severity was staged according to the POP-Q system. The χ(2) test and multivariate logistic regression analysis were used to determine POP risk factors. RESULTS: Of the 174 women included in the analysis, 106 (60.9%) had stage II POP or greater. In all, 93 women (53.4%) had cystocele, 63 (36.2%) had rectocele, and 37 (21.3%) had uterine prolapse. Univariate analysis identified high parity; young age at first delivery; menopause; squatting or standing position during delivery; and early return to work after delivery as risk factors for POP. Multivariate logistic regression revealed that delivery in a lying position presented a lower risk for cystocele than squatting or standing (odds ratio 0.34; P<0.01). CONCLUSION: Both LUTS and POP are common among women in rural Nepal. Cystocele is the most frequent, advanced, and symptomatic form of POP observed in this population.
