Pessary test to predict postoperative urinary incontinence in women undergoing hysterectomy for prolapse.

OBJECTIVE: We sought to demonstrate that a positive pessary test could predict postsurgical stress urinary incontinence in women with severe pelvic organ prolapse and that performing tension-free vaginal taping (TVT) could effectively prevent its occurrence. METHODS: Among the 79 patients evaluated for severe pelvic organ prolapse without symptoms of stress urinary incontinence, all underwent meticulous urogynecologic evaluations and pessary testing. In group 1, 32 patients had positive pessary tests and underwent vaginal hysterectomy, anterior and posterior colporrhaphy, and TVT. In group 2, 47 patients (17 of whom had positive pessary tests and 30 of whom had negative pessary tests) underwent vaginal hysterectomy and anterior and posterior colporrhaphy alone. A comparison in terms of surgical outcome and clinical manifestations was made between these 2 groups of patients. RESULTS: After surgery, a small proportion of patients had de novo idiopathic detrusor overactivity (7.6%, n = 6), urinary tract infections (7.6%, n = 6), mild recurrent prolapse (5.1%, n = 4), and urinary retention (3.8%, n = 3). Eleven (64.7%) of 17 patients with positive pessary tests who did not undergo TVT had urine leakage after their hysterectomies in contrast with the 30 patients who had negative pessary test, none of whom developed symptomatic stress urinary incontinence after vaginal hysterectomy. Among the 32 patients with positive pessary tests who had TVT with their hysterectomies, 3 developed urine leakage later; the cure rate was 90.6%. CONCLUSION: Continent patients suffering from severe pelvic organ prolapse but with a positive pessary test are considered to be at high risk of developing postoperative symptomatic stress urinary incontinence. Among the patients in our medium-range study, TVT effectively prevented postsurgical urinary incontinence. LEVEL OF EVIDENCE: II-1

Clinical outcome and placental territory ratio of monochorionic twin pregnancies and selective intrauterine growth restriction with different types of umbilical artery Doppler

Randomized Comparison of Tolterodine With Vaginal Estrogen Cream Versus Tolterodine Alone for the Treatment of Postmenopausal Women With Overactive Bladder Syndrome

To investigate whether vaginal estrogen cream combined with tolterodine is more effective than tolterodine alone in the treatment of postmenopausal women with overactive bladder (OAB).

Management of primary abdominal pregnancy: twelve years of experience in a medical centre

Background. The aim of this study was to evaluate our institutions 12‐year experience in managing primary abdominal pregnancy by laparotomy or laparoscopy. Methods. We identified 11 cases of primary abdominal pregnancy treated at our institution between January 1994 and December 2005, and separated the cases into 2 groups based on type of surgical management. The outcome measures we evaluated were operative time, blood loss and duration of hospital stay. In addition, the incidence rates for all types of ectopic pregnancy were recorded. Analysis excluded secondary abdominal pregnancy. Results. Of the 11 primary abdominal pregnancies, 6 were treated with laparotomy and 5 with laparoscopy. The laparoscopy group had significantly better results in operative time, blood loss and hospital stay (p<0.05). The difference in gestational age was not significant (p = 0.141), even after excluding the patient whose abdominal pregnancy was only identified after cesarean delivery. Conclusion. Our experience shows a trend toward better management of primary abdominal pregnancy with laparoscopy. These patients had shorter operative time, reduced blood loss, and fewer days in hospital then patients treated with laparotomy. Choice of management should depend on the patients condition, gestational age of the pregnancy, and the physicians clinical experience.

Postoperative urinary outcomes in catheterized and non-catheterized patients undergoing laparoscopic-assisted vaginal hysterectomy—a randomized controlled trial

The objective of this study is to assess the impact of bladder catheterization on the incidence of postoperative urinary tract infection (UTI) and urinary retention (PUR) following laparoscopic-assisted vaginal hysterectomy (LAVH). One hundred fifty patients undergoing LAVH were randomly assigned to no catheter use, 1-day, and 2-day catheter groups. The relationship between preoperative, intraoperative, and postoperative factors and the rates of UTI and PUR were determined. The incidences of UTI and PUR were 9.3% and 18.7%, respectively. The highest rate of UTI occurred in the 2-day catheter group; the highest rate of PUR occurred in no-catheter-use group. Multivariable logistical regression showed the duration of catheterization was the single predictor of UTI; duration of catheterization and diabetes mellitus were predictors for PUR. While short-term indwelling catheterization resulted in decreased rate of PUR, UTI rate increased among patients undergoing LAVH. Nonetheless, most patients resumed normal urination shortly after surgery.

Urodynamic and clinical effects of transvaginal mesh repair for severe cystocele with and without urinary incontinence

To demonstrate the urodynamic and clinical effects of transvaginal polypropylene mesh repair (TVM) for severe cystocele with or without stress urinary incontinence (SUI).

Resolution of elevated postvoid residual volumes after correction of severe pelvic organ prolapse

We hypothesized that elevated postvoid residual volume (PVRV) would resolve postoperatively in women with severe pelvic organ prolapse (POP) and investigated risk factors that might hamper its resolution. Retrospectively, we enrolled 57 patients undergoing surgery for severe POP. All patients had preoperative PVRVu2009≥u2009100xa0ml documented by ultrasound and catheterization. Presurgical voiding difficulty, urodynamic and cystoscopic data, and surgical outcome were analyzed. The incidence of postsurgical elevated PVRV was 15.8% and 3.5% was symptomatic. Patients with postsurgical elevated PVRV had larger preoperative residual volume than those with normal postsurgical PVRV (Pu2009=u20090.037). By multivariable analysis, concomitant anti-incontinence surgery was the single independent predictor of postsurgical elevated PVRV (odds ratiou2009=u20095.38, Pu2009=u20090.031). A majority of patients with severe POP had their elevated PVRV resolved postoperatively. Although concomitant anti-incontinence surgery increased the risk of developing elevated PVRV after repair, most remained asymptomatic.

Three‐dimensional power Doppler measurement of perfusion of the periurethral tissue in incontinent women – a preliminary report

Background. This study was designed to test the hypothesis that decreased periurethral vascularization and blood flow might lead to urinary incontinence. Three‐dimensional color histogram may better quantify the vasculature than traditional two‐dimensional Doppler ultrasound imaging.

Meconium peritonitis in utero---the value of prenatal diagnosis in determining neonatal outcome.

OBJECTIVEnMeconium peritonitis (MP) is a chemical peritonitis caused by fetal intestinal perforation in utero. Its incidence is rare, but serious neonatal morbidity or even mortality can occur if the diagnosis is not made until after birth. Prenatal diagnosis is important in prompting early postnatal surgical intervention, and so improving neonatal outcome.nnnMATERIALS AND METHODSnFourteen cases diagnosed in utero with MP from January 1996 to December 2005 were enrolled in this study. The final diagnoses were established by surgical findings or postnatal radiography. The prenatal ultrasound features, neonatal birth characteristics, surgical findings, postnatal management and neonatal outcomes were reviewed.nnnRESULTSnAll infants received follow-up care at our hospital. Prenatal ultrasound findings included fetal ascites (100%), intra-abdominal calcification (93%), dilated bowel loops (57%), pseudocysts (29%), and polyhydramnios (50%). Four infants (4/14; 28.5%) did not undergo postnatal surgery, but survived well. The mean gestational age at detection was significantly earlier in the non-surgery group (23+/-3.6 weeks) than in the surgery group (31.7+/-2.5 weeks). One infant (7.1%) died because of sepsis after two neonatal operations. The overall survival rate was 92.9%.nnnCONCLUSIONnMP can be diagnosed by prenatal ultrasound, and the neonatal outcome is favorable. Early detection is not associated with poor neonatal outcome, and selective termination is unnecessary. Resolution of dilated bowel loops and polyhydramnios predict a low rate of postnatal surgical intervention.

Significance of bladder trabeculation in postmenopausal women with severe pelvic organ prolapse: clinical and urodynamic assessments.

Objective Bladder trabeculation (BT) is a secondary result of bladder outlet obstruction (BOO), which may result from severe pelvic organ prolapse (POP) and cause lower urinary tract symptoms (LUTS). This study was conducted to investigate the relationship among clinical manifestations, urodynamic findings, and BT in women with severe POP. Methods We reviewed the medical records of patients with stage 3 or stage 4 POP who underwent prolapse surgical operation in a tertiary hospital between 2005 and 2011. All patients received preoperative evaluations, including urodynamic studies, cystoscopy, and a structured urogynecological questionnaire. Demographics, LUTS, pelvic floor symptoms, and urodynamic findings were compared between women with BT and women without BT. Results Of the 308 women included, 54.9% had BT and 12.7% were diagnosed with BOO (maximal flow rate <12 mL/s; detrusor pressure at maximal flow >20 cm H2O). Mean age, prevalence of urgency, urge incontinence, voiding difficulty, detrusor overactivity, and postvoid residual greater than 100 mL were significantly higher in women with BT than in women without BT. In addition, severe BT had significantly higher prevalences of detrusor overactivity, BOO, lower maximal cystometric capacity, urge incontinence, and anterior vaginal prolapse. Logistic regression demonstrated that detrusor overactivity was the only variable associated with BT. Conclusions More than half of the women with severe POP have BT, which, when compared with women without BT, indicates higher incidences of LUTS, detrusor overactivity, and urinary retention. An objective evaluation of BT should become a prerequisite examination for women with severe POP who would undergo prolapse surgical operation.OBJECTIVEnBladder trabeculation (BT) is a secondary result of bladder outlet obstruction (BOO), which may result from severe pelvic organ prolapse (POP) and cause lower urinary tract symptoms (LUTS).
