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.

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.

Prospective randomized trial of polyglactin 910 mesh to prevent recurrence of cystoceles and rectoceles.

OBJECTIVE: Our aim was to evaluate the efficacy of polyglactin 910 mesh in preventing recurrent cystoceles and rectoceles. STUDY DESIGN: In a prospective, randomized, controlled trial, patients undergoing vaginal reconstructive surgery with cystoceles to the hymenal ring and beyond were randomly selected to undergo anterior and posterior colporrhaphy with or without polyglactin 910 mesh reinforcement. Results were evaluated preoperatively and at 2, 6, 12, and 52 weeks postoperatively. RESULTS: A total of 161 women were randomly selected for this study. One woman was excluded at the time of surgery, and 17 women were lost to follow-up. Eighty women received mesh, and 80 did not. Both groups were found to be equivalent with respect to age, parity, concomitant surgery, and menopausal and hormone replacement status. Preoperatively 49 women had a central cystocele to the hymenal ring and 111 women had cystoceles beyond the introitus; 91 women had a rectocele to the mid-vaginal plane, 31 to the hymenal ring, and 22 beyond the introitus. After 1 year, 30 (43%) of 70 subjects without mesh and 18 (25%) of 73 subjects with mesh had recurrent cystoceles beyond the mid-vaginal plane (P =.02). Eight women without mesh and 2 women with mesh had recurrent cystoceles to the hymenal ring (P =.04). No recurrent cystoceles beyond the hymenal ring occurred in either group. Multivariate logistic regression analysis showed concurrent slings to be associated with significantly fewer recurrent cystoceles (odds ratio, 0.32; P =.005), whereas the presence of mesh remained significantly predictive of fewer cystocele recurrences in this analysis. Thirteen recurrent rectoceles were noted 1 year postoperatively, with no differences between groups. CONCLUSION: Polyglactin 910 mesh was found to be useful in the prevention of recurrent cystoceles.

Compliance with Papanicolaou smear screening following tubal ligation in women with cervical cancer.

To evaluate patient compliance with Papanicolaou (Pap) smear screening after tubal ligation compared with other methods of birth control in patients who develop cervical cancer, a retrospective review of 262 women with cervical cancer diagnosed at age < or = 70 years was undertaken at the Albert Einstein College of Medicine from January 1987 to December 1995. Demographic data, stage of the disease, histologic type, history of smoking, history of sexually transmitted disease (STD), and birth control use were recorded. The Pap screening history was obtained from all the patients. Women who had a bilateral tubal ligation (BTL) were compared with those who did not have this form of birth control. The date and result of their last Pap test prior to their diagnosis of cervical cancer was noted. Two hundred fourteen women with cervical cancer were evaluable. The clinical stage, mean age, history of smoking, and history of STD were similar for both groups. Gravidity among the BTL group was higher than in the non-BTL group (p < 0.01). Forty-eight (22.4%) women had a previous BTL. Twenty-seven of these 48 patients (56.3%) did not have a Pap smear within 3 years prior to the diagnosis of cervical cancer. Of the 166 patients, 61 (36.7%) did not have a Pap test within 3 years (p < 0.05). Fourteen women (29.2%) in the tubal ligation group never returned for a Pap test following the BTL. An average of 6.2+/-5.9 years elapsed since the last Pap test in the BTL group, with 4.0+/-5.1 years in the nontubal ligation group (p < 0.05). There was a correlation between the number of years since BTL (14.2+/-7.7) to the number of years since the last Pap test (6.2+/-5.9) (p < 0.05). Women who have had a BTL should be considered high risk because of poor screening compliance. A Pap test every 3 years is not adequate in this high-risk population group. We advocate improved counseling regarding the importance of continued annual Pap screening for women who are considering tubal ligation.

Treatment of detrusor instability with oxybutynin rectal suppositories.

Our aim was to determine whether oxybutynin hydrochloride suppositories can be used as a treatment for detrusor instability in patients who have not been able to tolerate oral pharmacological agents. A retrospective chart review of 25 women diagnosed with detrusor instability and treated with oxybutynin rectal suppositories was conducted. Each suppository contained 5 mg oxybutynin, 15 mg micronized Sila gel, and 1.25 g of a fatty acid base. Patients were started on one suppository twice daily and then dose titrated as tolerated. The range of the total daily dose was 5-20 mg. Nine of 25 women (36%) had greater than a 50% overall subjective improvement and 3 (12%) had some improvement. Seven of the 12 responders (58%) continued to use the suppositories for a prolonged period of time (> 90 days). The most common side effects reported were dry mouth 48% and constipation 14.3%. One patient with polymyositis developed a serious anticholinergic reaction which required hospitalization. It was concluded that patients who are unable to tolerate oral anticholinergic and antispasmodic agents for the treatment of detrusor instability may benefit from oxybutynin rectal suppositories.

Transient alteration in fetal biophysical profile immediately following fetomaternal hemorrhage sustained during motor vehicle accident.

Transient altered fetal behavior manifested by decreased fetal biophysical score at 37 weeks' gestation following maternal injuries sustained in a motor vehicle accident, represented an immediate fetal response to fetomaternal hemorrhage occurring during the accident. Although cesarean delivery had initially been considered due to fetal distress (fetal biophysical score of 4 of 10), the fetal biophysical score improved within 2 hr, permitting spontaneous vaginal delivery of a nonasphyxiated fetus, 24 hr after the traumatic event. To our knowledge this is the first report of a transient abnormal fetal biophysical profile in association with a large fetomaternal hemorrhage.

The evaluation includes a detailed history, physical examination, invasive and non-invasive testing. An algorithm for laboratory tests, procedures and follow-up recommendations is presented.

The binding of fluorescent 4,6,8(14)-triene-3-one steroids to cyclodextrins as a model for steroid-protein interactions.

The 4,6,8(14)-triene-3-one steroids, highly fluorescent in aqueous solutions, lose their fluorescence power when binding occurs to hydrophobic regions of other molecules, such as the hydrophobic cavity in the ring system of cyclodextrins. The fluorescence intensity decreases almost completely when beta- and gamma-cyclodextrins are present in the solution. Scatchard plots derived from fluorescence titrations show that one or two molecules of steroid bind to one cyclodextrin molecule with KD,F-values of about 10(-4)-10(-5) mol/liter. Temperature-jump experiments show a single relaxation process, with rate constants for the decay of the beta-cyclodextrin-steroid complexes of about 10(4)-10(5) per s. For alpha- and gamma-cyclodextrins such relaxation processes are not observed.
