Early-stage ovarian carcinoma presenting with irritative voiding symptoms and urge incontinence.

The detection of ovarian cancer remains a major challenge for gynecologists, as the majority of cases are symptomatically silent until regional metastases or ascites have occurred. This report examines a case of early-stage ovarian adenocarcinoma presenting with irritative voiding symptoms and urge incontinence, all of which resolved fully following surgery. We also report on the frequency of lower urinary tract symptoms leading to the detection of early-stage ovarian cancer, within a cohort of 52 consecutive patients surgically treated at our institution. Lower urinary tract symptoms may trigger the diagnosis of early ovarian cancer in up to 11% of surgically managed patients at our institution. To our knowledge there are no previous reports of early ovarian cancer causing transient irritative voiding symptoms or urge incontinence. This report highlights the importance of considering ovarian neoplasm as a relatively uncommon but critically important etiology accounting for these common female urologic complaints.

Anterior or posterior sacrospinous vaginal vault suspension: long-term anatomic and functional evaluation.

OBJECTIVE: To compare vaginal anatomy and sexual function after the conventional posterior and anterior sacrospinous vault suspension. METHODS: A retrospective repeated measures cohort study included all 168 consecutive sacrospinous vault suspension procedures between July 1990 and February 1997. The posterior suspension (n = 92) used a posterior vaginal incision and pararectal dissection. Anterior suspension (n = 76) involved an anterior rather than posterior vaginal incision, retropubic perforation, and dissection of a paravaginal-paravesical rather than pararectal space to accommodate the vaginal vault. Two polytetrafluoroethylene (00) sutures anchored the anterior vaginal cuff (for the anterior sacrospinous suspension) or the posterior vaginal cuff (for the posterior sacrospinous suspension) to the ligament. Postoperative evaluation included an examination using the pelvic organ prolapse quantitative system, assessment of vaginal width and axis, and symptom questionnaire. RESULTS: Total vaginal length and apical suspension were slightly greater after the anterior suspension, and recurrent anterior vaginal relaxation was less likely. No differences were found in maximal dilator size or apical narrowing between the two groups. New onset dyspareunia was reported by two subjects in the anterior vault suspension group, and two in the posterior vault suspension group. Three of these four cases of de novo dyspareunia were attributable to either severe atrophy or recurrent prolapse, and none to vaginal narrowing or shortening. CONCLUSION: After anterior sacrospinous vault suspension, vaginal length and apical suspension were slightly increased, and recurrent anterior vaginal prolapse decreased compared with the posterior sacrospinous suspension technique. Upper vaginal caliber and sexual function appear well preserved using either technique.

Comparison of microtransducer and fiberoptic catheters for urodynamic studies.

OBJECTIVE: To assess the validity and reproducibility of a fiberoptic transducer urodynamic catheter for urethral closure pressure profiles and leak point pressure determination, using a microtransducer catheter as the standard. METHODS: Ninety women without significant pelvic organ prolapse underwent urodynamic evaluations with both fiberoptic and microtransducer catheters. Maximal urethral closure pressures and "leak point pressures" were repeatedly measured by the two catheters and statistically compared. The order of catheter use was randomized. RESULTS: Significantly lower mean maximal urethral closure pressures were recorded by the fiberoptic system than by the microtransducer system (28.9 cmH(2)O +/- 17.3 versus 43.2 cmH(2)O +/- 24.9, P <.001). The fiberoptic catheter predicted microtransducer values for maximum urethral closure pressure only within a range of 27 cmH(2)O. Mean "leak point pressure" recorded by the fiberoptic catheters (66.9 cmH(2)O +/- 2.9) was not significantly different than that recorded by the microtransducer catheters (66.4 cmH(2)O +/- 2.9, P =.97). CONCLUSION: There is a significant difference between maximum urethral closure pressure values recorded by the microtransducer and fiberoptic catheter systems. No significant difference was found between the two systems in measurement of Valsalva "leak point pressure."

Protective effect of suburethral slings on postoperative cystocele recurrence after reconstructive pelvic operation.

OBJECTIVE: The purpose of this study was to evaluate the independent effect of suburethral sling placement on the risk of cystocele recurrence after pelvic reconstructive operation. STUDY DESIGN: One hundred forty-eight women with cystoceles to or beyond the hymenal ring underwent pelvic reconstructive operation, with or without incontinence procedures, and were evaluated at 12 and 52 weeks after operation with a standardized pelvic examination. Rates of recurrent prolapse, at all sites, were statistically compared between subjects with and without suburethral slings. A multiple regression analysis was used to determine the independent effect of sling placement on the risk of recurrent cystoceles. RESULTS: Suburethral sling placement was associated with a 54.8% reduction in the mean rate of postoperative cystocele recurrence (P =.004). This protective effect was observed as early as 12 weeks and remained significant at 1-year follow up (42% vs 19%). A markedly reduced risk of cystocele recurrence was observed when women with sling procedures were compared with all other women, with those women who underwent other incontinence operations, and even with those women who had undergone prolapse repair with no incontinence procedure. The protective effect of the sling procedure remained highly significant (odds ratio, 0.29; P =.0003), even after controlling for potentially confounding variables in a multiple logistic regression model. CONCLUSION: Suburethral sling procedures appear to significantly reduce the risk of cystocele recurrence after pelvic reconstructive operation, in contrast with the effect of retropubic urethropexy and needle suspensions. These findings should be considered when the surgical treatment of stress incontinence that accompanies pelvic organ prolapse is being planned.

Transvaginal therapy of genuine stress incontinence.

Two minimally invasive techniques for treatment of genuine stress incontinence, a transvaginal retropubic urethropexy and a transvaginal sling, using Cooper's ligament as the anchoring structure, are reported along with the early results. These surgeries can be done easily in conjunction with vaginal reconstructive procedures. Twenty-seven women were operated on between October 1998 and September 1999. Seventeen women underwent the transvaginal retropubic urethropexy for genuine stress incontinence, whereas 10 women underwent the transvaginal sling for genuine stress incontinence with maximal urethral closure pressures less than 20 cm H(2)O. Postoperative urodynamics were done routinely at 4 months. Subjective follow-up was by routine postoperative visits or telephone survey. The mean follow-up of the retropubic urethropexy group was 6.5 months (range 1 to 12). Of these 17 women, 16 (94%) had no stress incontinence. Seven of 14 patients (50%) resolved their urge incontinence also. The mean follow-up of the transvaginal sling group was 2.8 months (range 1 to 4.5). Of the 10 patients in this group, 7 (70%) were cured of their stress incontinence. One patient in each group underwent only the anti-incontinence procedure without concomitant vaginal reconstructive procedures; both of these women were dry. Additional follow-up is required to see if these minimally invasive techniques produce successful results in the long term.

A C-arm fluoroscopy-guided progressive cut refinement strategy using a surgical robot.

We describe a new method to cut a precise, high-quality femoral cavity in Revision Total Hip Replacement surgery (RTHR) using a surgical robot and an intra-operative C-arm fluoroscope. With respect to previous approaches, our method contains several new features. (1) We describe a novel checkerboard plate designed to correct the geometric distortion within fluoroscopic images. Unlike previous distortion correction devices, the plate does not completely obscure any part of the image, and the distortion correction algorithm works well even when there are some overlaid objects in the field of view. (2) Also included are a novel corkscrew fiducial object designed to be integrated with the robot end-effector, and a 6D pose estimation algorithm based on the two-dimensional (2D) projection of the corkscrew, used in robot-imager registration and imager co-registration. (3) In addition, we develop a cavity location algorithm, which utilizes image subtraction and 2D anatomy contour registration techniques. (4) Finally, we propose a progressive cut refinement strategy, which progressively improves the robot registration during the procedure. We have conducted several experiments, in both simulated and in vitro environments. The results indicate that our strategy is a promising method for precise orthopedic procedures like total hip replacement.

Electromagnetic pelvic floor stimulation: applications for the gynecologist.

The therapeutic potential of magnetic energy has been a subject of long-standing interest within both conventional and alternative medical practice. Numerous devices using magnetic fields, ranging from the dubious to truly innovative, have claimed a wide variety of clinical benefits. For gynecologists involved with the diagnosis and treatment of pelvic floor and bladder dysfunction, magnetic stimulation of the sacral nerve roots and peripheral nerves continues to evolve as a noninvasive treatment alternative. The conduction characteristics of magnetic energy confer several practical advantages for its use. This article reviews the use of electromagnetic stimulation for treatment of common urogynecologic conditions, and provides an historical overview of the therapeutic application of electromagnetic energy.

Cultural elements of postpartum depression. A study of 327 Jewish Jerusalem women.

OBJECTIVE: To examine the social, cultural and religious factors underlying postpartum depression within a cultural cross-section of Jewish Jerusalem women. STUDY DESIGN: A prospective, repeated-measures study of 327 women. The Edinburgh Postpartum Depression Scale (EPDS) was administered immediately postpartum and 6-10 weeks later. Detailed sociodemographic information included perceptions of the pregnancy, community supports and religious affiliation. Odds ratios, 95% confidence interval and P values were calculated for all covariates. Multiple logistic regression was performed to estimate the degree of independent association between religiosity and postpartum depression. RESULTS: Postpartum depressive symptoms significantly associated with secular affiliation (odds ratio [OR] 2.9 [1.3-6.3] and tended toward an inverse association with orthodox affiliation (OR 0.6 [0.3-1.3]). Across secular, traditional, religious and orthodox groups, there was a decreasing trend in EPDS mean scores. Other predictors of depressive symptoms were psychiatric history, immigrant status and poor support with newborn care. CONCLUSION: Our study sample was particularly suitable for the assessment of cultural and religious elements of postpartum depression. We found religiosity, with its associated social and community structuring and well-defined social roles, to be significantly associated with self-reported postpartum depressive symptoms. These findings suggest that cultural factors, including role definitions, community support and rituals, may explain discrepancies found in the incidence of postpartum depression.

Pregnancy after medical management of a uterine arteriovenous malformation. A case report.

BACKGROUND: The natural history of conservatively managed uterine arteriovenous malformations is largely unknown, and the risks associated with subsequent pregnancy and vaginal delivery have not been established. CASE: A multiparous woman with a previously reported history of uterine arteriovenous malformation was monitored throughout pregnancy and vaginal delivery. Serial ultrasound studies were performed prior to a successful induction of labor for severe preeclampsia at 34 weeks' gestation. CONCLUSION: To our knowledge, this is the first report of pregnancy and vaginal delivery in a woman with a prior history of a medically managed uterine arteriovenous malformation. Noninvasive treatment of uterine arteriovenous malformations is rare, and the potential long-term risks of this approach, including pregnancy, remain uncertain.

Computed tomography of axillary and supraclavicular adenopathy.

The normal cross-sectional anatomy of the axillary and supraclavicular regions is demonstrated. One hundred and sixty chest computed tomography scans were reviewed and criteria for differentiating normal axillary and supraclavicular structures from enlarged lymph nodes established. Axillary structures 14 mm or larger are suggestive of axillary adenopathy. Axillary structures 10-13 mm in size raise the possibility of adenopathy.

Shoulder arthrography: comparison of morbidity after use of various contrast media.

This prospective study compares immediate and delayed patient discomfort in 177 patients following shoulder arthrography using intraarticular combinations of metrizamide, meglumine/sodium diatrizoate, meglumine diatrizoate, lidocaine, epinephrine, and air. Patients receiving conventional ionic monomeric positive contrast media had a 60% (90/150) incidence of moderate or severe delayed exacerbation of their baseline symptoms; only 14% (3/21) of patients receiving metrizamide, a nonionic contrast medium, had similar levels of postprocedural discomfort. Morbidity was somewhat diminished with the use of double-contrast (45%, 34/75) rather than single-contrast (75%, 56/75) examinations, and with avoidance of sodium-containing contrast agents or epinephrine. Nonionic or monovalent polymeric contrast media, despite their present high cost, may be the agents of choice if single-contrast arthrography is performed in joints (such as the shoulder, hip, and temporomandibular) associated with a high incidence of post-procedural pain.

Aluminum hydroxide gel bezoar--CT diagnosis.

An obstructing aluminum hydroxide gel bezoar was first recognized on a retrograde gastrografin study through an ileostomy. In retrospect, a computed tomographic (CT) scan had demonstrated the bezoar as a high density intraluminal mass surrounded by somewhat less dense contrast material distending the bowel. A CT image of a phantom made of aluminum hydroxide gel surrounded by gastrografin was remarkably similar.

Prediction of vertebral body compressive fracture using quantitative computed tomography.

We performed quantitative computed tomography in vitro on the first and third lumbar vertebrae in human cadavera using a dibasic potassium phosphate phantom for calibration. The quantitative computed-tomography numbers exhibited a significant positive correlation (R2 = 0.89, p less than 0.0001) with direct measurements of the apparent density of the vertebral trabecular bone. We also conducted uniaxial compression tests to failure of the vertebral bodies after removal of the posterior elements, and found that vertebral compressive strength was also correlated at a high level of significance (R2 = 0.82, p less than 0.0001) with direct measurement of the trabecular apparent density. These findings suggested the possibility that the quantitative computed-tomography values might be directly predictive of vertebral compressive strength. However, when we correlated the quantitative computed-tomography values directly with vertebral compressive strength, the results (R2 = 0.46, p less than 0.061) were suggestive but not quite significant. All vertebral bodies failed by compression of the end-plate, suggesting only a modest structural role for the cortical shell under these loading conditions. This was confirmed by comparing the compressive load to failure of twenty additional pairs of vertebrae that were tested with and without an intact vertebral cortex. Removal of the cortex was associated with approximately 10 per cent reduction in vertebral load to failure.
