Background and Aim: This study was conducted to evaluate the safety and efficacy of Tension-free Tape for the surgical treatment of female stress urinary incontinence.

Materials and Methods: In a prospective open study for pre and post operative, we followed 36 patients at least 1.5 years after surgery (18-28 months) all patients underwent the operation under local anesthesia, allowing the surgeon to check intra-operatively that continence has been obtained.

Results: Mean operation time was 36 minutes (range 20-45 minutes). 32(89%) of the patients was cured according to the protocol, another 3(8.3%) were significantly improved and there was 1(2.7%) failure. Mast of patients (about 91%) were operated on a one day-care basis, which implies that they were released from the hospital the day after the procedure, and no post operative catheterization, defect healing and tape rejection occurred. Pain free recovery time without any analgesic was another benefit. Five patients needed an indwelling catheter for 3 days and two uncomplicated hematoma occurred.

Conclusion: Based on the results, we conclude that Tension-free Vaginal Tape is a safe and effective ambulatory procedure for surgical treatment of genuine stress urinary incontinence, which allows the majority of the women to be discharged from the clinic the day after the procedure and start their works in the second week.

Background: We evaluated the efficacy of botulinum-A toxin (BTX-A) injection into detrusor muscle in patients with incontinence resistant to anticholinergic drugs due to detrusor overactivity.

Methods: Our prospective study included 12 male patients with detrusor overactivity and incontinence due to spinal cord injury, which had been unsuccessfully treated with anticholinergic medication. Under visual control through the cystoscope 300 units of BTX-A were injected into detrusor muscle at 30 sites, sparing the trigone. After the treatment patients continued to perform clean intermittent self-catheterization (CIC) and clinical follow-up was planned for 6 weeks, 6 months and 9 months after treatment and urodynamic study was repeated after 6 weeks.

Results: At the 6-week follow-up complete continence was restored in  9 of the 12 patients and after 6 months of 9 continent patients 1 patient lost his follow-up  from the study and 7 were still continent. After 9 months 3 patients remained continent. Mean cystometric bladder capacity (p<0.001), compliance (p<0.001), and mean post-void residual urine volume significantly increased (p<0.001), whereas maximal detrusor contraction pressure significantly decreased (p<0.001).

Conclusions: BTX-A injections appears to be an effective and safe therapeutic option for overactive bladder in adult patients with spinal cord injury failing anticholinergic therapy even if these patients present with very low bladder compliance. Patients may require repeated injections after 6 months to remain continent.

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Pelvic Organ Prolapse (POP) and related urinary symptoms are frequent disorders in elderly women and their management improves life expectancy and quality of life. Urodynamic tests applied in pathophysiologic diagnosis and treatment of urinary disorders are not always cost effective. This study aims to evaluate the results of Urodynamic tests in patients with pelvic organ prolaps.
Methods: This case- control study was done using UDI-6 questionnaire during 18 months in vali-e-asr clinic of Imam Khomeini Hospital, Iran with 105 cases of POP the cases were divided into two groups: group one (66 cases with urinary incontinency) and group two (39 without incontinency) and assessed with urodynamic tests.
Results: Based on UDI-6, the patients of group one had more clinical symptoms (frequency, urine leakage, urge incontinence and stress incontinence). (p<0.001). Except for first desire to voide and normal voided volume indices, there were no significant differences in the other urodynamic parameters in two groups. Sensitivity and specificity of urgency leak in group one was 22 and 68/8% and in group two was 30 and 65/5% respectively. Stress leak sensitivity and specificity in group one were 25/4% and 100% and in group two were 57/1% and 71/9% respectively.
Conclusion: In this study, considering sensitivity and specificity of symptoms and urodynamic test for urinary incontinency assessment is advised in patients with POP who need surgery.

Background: To examine the association among pelvic girdle pain (PGP), urinary incontinence (UI) and pelvic floor muscle (PFM) function in pregnant women in second and third trimester.

Methods: 300 pregnant women who admitted for standard pregnancy care were enrolled in the study. Urinary incontinency was measured via the international consultation on incontinence questionnaire short form. Pelvic girdle pain was diagnosed according to existing guidelines. Vaginal examination assessed pelvic muscles contract- relax patterns and muscle strength. The software stata version 13 (Stata Corp., TX, USA) was used for data analysis.

Results: Overall 300 women (150 with PGP and 150 without PGP) were included in final analyses. There was not significant differences between the demographic data including, body mass index before pregnancy, maternal age, mode of delivery. Prevalence of urinary incontinence in women with pelvic girdle pain was 41.5 percent (CI 95%: 32.01- 51.48) while the prevalence of urinary incontinence in women without pain was 21.9 percent (CI 95%: 14.99-30.03). Using logistic regression, the relationship between urinary incontinence and pelvic girdle pain was significant. (CI 95%: 1.07-3.31, P=0.02). Multivariate logistic regression analysis was used to evaluate the relationship between PGP and pelvic floor muscle function and results showed that pelvic floor muscle strength in women with PGP was significantly lower than women without PGP. (CI 95%: 0.24-0.68, OR= 0.4, P<0.001). The duration of the contraction of the pelvic floor muscles in patients with PGP was significantly shorter than women without PGP. (CI 95%: 0.21-0.60, OR =0.35, P<0.001).

Conclusion: There was a significant association between pelvic girdle pain and urinary incontinence during the second and third trimesters of pregnancy and also the pelvic floor muscle strength and duration of the contraction of the pelvic floor muscles in women with pelvic girdle pain was significantly lower than those without PGP.
