Sacrospinous hysteropexy with a low weight transvaginal polypropylene mesh for treatment of complete uterovaginal eversion.

INTRODUCTION: Pelvic Organ Prolapse (POP) is a common condition in elderly resulting from the weakening of the organ suspension elements of multifactorial origin. It compromises significantly the quality of life and can affect more than 50% of multiparous women. Stage IV prolapse or complete uterovaginal eversion corresponds to 10% of the cases and the only form of curative treatment is the surgical correction. The aim of this video is to demonstrate our technique of sacrospinous hysteropexy with a low weight transvaginal polypropylene mesh for treatment of this challenge condition, focusing on technical details in order to prevent mesh related complications. Major, but rare complications, include: infection, prolapse recurrence, abscess formation, bladder perforation and urinary fistula. These situations are related mostly to low volume centers. MATERIALS AND METHODS: A 70 years old female with a stage IV POP had obstructive lower urinary tract symptoms. Only after reducing prolapse, it was possible to urinate, but without stress urinary incontinence. No topic estrogen was prescribed before the surgery and she also didn´t take any kind of hormone replacement therapy. Transvaginal ultrasound and the Pap smear screening were done with normal results. Cystoscopy wasn´t employed at anytime of this procedure. Hydrodissection of vaginal wall was followed by longitudinal incision from the level of bladder neck to the cervix. Notice that the ideal dissection should maintain the vaginal thickness, and address the plane of the connective tissue between the bladder and the vagina. Bladder base is then released from the anterior aspect of the cervix in order to create a site to pericervical ring repair and to fix the apex of the Calistar Soft® with polypropylene 3.0 stitches. A blunt dissection extended downwards through the lateral aspect of the levator ani fascia till the identification of the ischial spine and sacrospinous ligaments bilaterally. Two polypropilene 2.0 threads mounted on a specially designed tissue anchor system (TAS) are then fixed into each sacrospinous ligament 1.5 to 2 cm away from the ischial spine and repaired for further prosthesis anchoring. Then, a longitudinal incision is done at the posterior vaginal wall and the recto-vaginal fascia detachment from the posterior aspect of the pericervical ring is identified and corrected with interrupted polypropylene 2.0 stitches to the cervix and to the pericervical aspect of elongated uterosacrus ligaments bilaterally. The Calistar Soft A (anterior) and P (posterior)® prosthesis were fixed at the anterior and posterior aspects of the cervix, respectively, with interrupted polypropylene 3.0 stitches and meshes' arms are fixed to the sacrospinous ligament using the previously implanted TAS. Then, the distal Calistar Soft A® arms were bilaterally fixed into the internal obturator muscles using its fish spine-like multipoint fix device in order to prevent mesh folding. Finally, perineal body repair was done and vaginal wall was closed with individual absorbable interrupted polyglactin 2.0 sutures and a 16 Fr Foley catheter as well as a vaginal pack embedded on neomicin-bacitracin cream were kept overnight. RESULTS: A high satisfaction rate has been computed with synthetic mesh to POP surgery correction. Approximately 10% of cases of mesh exposure may occur, most of them oligosymptomatic and easy handed by excision or with topic estrogen preparations. After 1 year follow-up, our patient is still satisfied without any complain and no relapse. CONCLUSION: We described a successful treatment of stage IV POP in an old female patient. This technique can be used for advanced end stage POP patients, especially those with some contraindication to sacropromontopexy, but who want to keep vaginal length and uterus. Anatomical knowledge, obedience to technical care, and intensive training are the keys for minimizing the risk of complications. Although we had success with this technique, more studies with proper randomization are necessary to compare success and complications of sacrospinous hysteropexy with a low weight transvaginal polypropylene mesh to sacropromontopexy.

Global Postural Re-education: an alternative approach for stress urinary incontinence?

OBJECTIVE: The aim of this study was to evaluate the impact of Global Postural Re-education (GPR) on stress urinary incontinence symptoms and to compare it to Pelvic Floor Muscle Training (PFMT). STUDY DESIGN: Fifty-two women with stress urinary incontinence were distributed into two groups: Group 1 (G1) was submitted to weekly sessions of GPR for three months and Group 2 (G2) performed Pelvic Floor Muscle Training four times a week for three months. Patients were evaluated through the King's Health Questionnaire, a three-day voiding diary including daily pad use and a Functional Evaluation of the Pelvic Floor (FEPF), before treatment (T0), at the end of treatment (T1) and six months after treatment (T2). RESULTS: The number of leaking episodes dropped significantly in both groups at the end of treatment and at six months follow-up, with a significantly greater decrease in G1. Daily pad use dropped significantly in both groups. At the end of treatment, 72% of the patients in G1 and 41% of the patients in G2 needed no pads and at six-month follow-up, 84% and 50%, respectively. FEPF improved significantly in both groups, with no significant difference between the groups (P=0.628). The King's Health Questionnaire demonstrated significant improvement in both groups and in all domains. The GPR group presented higher adherence to treatment, with no dropouts. CONCLUSIONS: GPR could represent an alternative method to treat stress urinary incontinence in women, should the results be long lasting.

Technetium-99m-L,L-ethylenedicysteine is more effective than technetium-99m diethylenetriamine penta-acetic acid for excluding obstruction in patients with pyelocalicinal dilation.

OBJECTIVE: To evaluate the utility of diuretic dynamic renal scintigraphy (DDRS) with technetium-99m-L,L-ethylenedicysteine ((99m)Tc-EC) in patients with indeterminate or possible false-positive results for urinary obstruction by technetium-99m diethylenetriamine penta-acetic acid ((99m)Tc-DTPA) DDRS. METHODS: A total of 92 patients (63 male; mean age, 16.6 +/- 21.25 years) were studied, with a total of 103 kidneys presenting indeterminate (20/103) or possible false-positive results for obstruction attributable to reduced renal function or severe kidney dilation (83/103) by (99m)Tc-DTPA DDRS (<60% of radiopharmaceutical excreted in 20 minutes-half-time clearance [T(1/2)] >15 minutes). Patients were reimaged after intravenous injection of (99m)Tc-EC, with dynamic images before and after furosemide administration using the same acquisition parameters applied in the previous (99m)Tc-DTPA study. Time interval between (99m)Tc-DTPA and (99m)Tc-EC renograms was 2-64 days. The percentage of excreted material 20 minutes after furosemide was calculated using both radiopharmaceuticals, and were statistically compared using the paired samples t test. RESULTS: The excretion after furosemide injection was 25.3% +/- 18.2% for (99m)Tc-DTPA and 41.2% +/- 26.1% for (99m)Tc-EC, with a statistically significant difference between both radiopharmaceuticals (P <.0001). Using (99m)Tc-EC obstruction was excluded in 36 of 103 kidneys, which excreted >60%. A total of 10 of 83 kidneys (12.0%) with an obstructive pattern by (99m)Tc-DTPA study turned out to be indeterminate by (99m)Tc-EC DDRS. There was an agreement between (99m)Tc-EC and (99m)Tc-DTPA studies in 54 of 83 kidneys with obstructive (65.1%) and in 3 of 20 (15.0%) with indeterminate patterns. CONCLUSIONS: (99m)Tc-EC was more effective than (99m)Tc-DTPA for excluding obstruction, presenting less false-positive and indeterminate results. (99m)Tc-EC can substitute (99m)Tc-DTPA to evaluate patients with urinary tract dilation.

The Portuguese validation of the International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS) for Brazilian women with pelvic organ prolapse.

The aim of this study is to validate the International Consultation on Incontinence Questionnaire-Vaginal Symptoms (ICIQ-VS) in Portuguese. Two hundred four women (108 symptomatic, 94 asymptomatic, and two with no data) with mean age of 55.4 years received a Portuguese version of the ICIQ-VS. Clinical data and pelvic organ prolapse quantification index (POP-Q) were obtained. Retest was performed 3 weeks later. Responsiveness was assessed after 20 weeks of postsurgical follow-up. Overall, most patients presented POP-Q > 2. ICIQ-VS demonstrated good psychometric properties (validity, reliability and responsiveness). The test-retest reliability was moderate to excellent for all questions. The construct validation distinguished differences in ICIQ-VS scores between symptomatic (ICIQ-VS5a > 0) and asymptomatic (ICIQ-VS5a = 0) women. ICIQ-VS was highly responsive to surgical treatment and discriminated between levels of change in the vaginal symptoms score, sexual matters score, quality-of-life score, and POP-Q. The Portuguese version of ICIQ-VS was successfully validated.

Histopathological alterations of the vas deferens in rats exposed to polypropylene mesh.

OBJECTIVE: To assess the histological and physiological effects of polypropylene mesh for inguinal herniorraphy, as it can cause lesions in the vas deferens in 0.3-2.0%, leading to infertility, and induces an inflammatory process and adjacent fibrosis, strengthening the posterior inguinal wall. MATERIALS AND METHODS: In all, 40 male albino rats (3 months old) had bilateral vas deferens dissection followed by mesh implantation on one side; the contralateral side was used as the control. The rats were killed 90 (group 1) and 120 (group 2) days later, and the vas deferens, epididymides and testicles assessed histopathologically. RESULTS: There was a foreign-body reaction after mesh implantation, but not in the controls. The mean lumen dilatation in regions proximal to the mesh in groups 1 and 2 was 0.468 and 0.371 mm(2), respectively, and all the sections had spermatozoids. The mean dilatation in control groups 1 and 2 was 0.239 and 0.170 mm(2), respectively, with spermatozoids present in 58% and 75%, respectively (significant, P < 0.05). In group 1 the wall thickness of mesh-implanted segments reduced to 0.177 mm, and in segments proximal to the mesh to 0.099 mm; the control segment was 0.298 mm (P < 0.05). In group 2 the mean thickness of mesh-implanted and proximal segments was 0.134 and 0.224 mm, respectively, while in the control it was 0.284 mm (not significant). There was loss of mucosal folding in all segments proximal to the mesh but not in the control. The epididymides and testicles were unchanged. CONCLUSION: Polypropylene mesh induces a foreign-body reaction, with histological changes in the vas deferens that cause functional obstruction, with dilatation and spermatozoid repression.

Effect of dose escalation on the tolerability and efficacy of duloxetine in the treatment of women with stress urinary incontinence.

To assess the impact of duloxetine dose escalation on tolerability and efficacy, 516 women with stress urinary incontinence were randomized to receive placebo or duloxetine in one of three regimens: 40 mg BID for 8 weeks, 40 mg QD for 2 weeks escalating to 40 mg BID for 6 weeks or 20 mg BID for 2 weeks escalating to 40 mg BID for 6 weeks. A non-inferiority analysis confirmed that the 20 mg BID starting dose was significantly better than the other two duloxetine regimens for nausea reduction (16.5% vs 25.2% and 29.4%). There were also significant differences in the discontinuation rates (7.5% vs 11.8% and 16.2%). The efficacy after 4 weeks was significantly better with duloxetine than with placebo. Starting duloxetine at 20 mg BID for 2 weeks before increasing to 40 mg BID significantly improved tolerability but did not impact duloxetine efficacy after all the subjects had been on 40 mg BID for at least 2 weeks.

Massive prolapse of the urethral mucosa following periurethral injection of calcium hydroxylapatite for stress urinary incontinence.

The injection of bulking agents into the urethral submucosa is designed to create artificial urethral cushions that can improve urethral coaptation and hence restore continence. Ideally, a urethral bulking agent should be non-immunogenic and biocompatible, leading to minimal inflammatory and fibrotic response. The authors present a case report of a granulomatous reaction leading to urethral prolapse, 3 months after the transurethral injection of calcium hydroxylapatite. To our knowledge, this is the first granulomatous reaction described after calcium hydroxylapatite injection.

Responsiveness to the Portuguese version of the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) after stress urinary incontinence surgery.

OBJECTIVE: To evaluate the reliability and responsiveness (internal and external) of the Portuguese version of the ICIQ-SF. We assessed the responsiveness of the ICIQ-SF after surgical procedures for the treatment of stress urinary incontinence. MATERIALS AND METHODS: Prospective open label study in 2 tertiary referral centers. Sixty-one patients of both genders (54 female and 7 male) were enrolled. Patients were treated using surgical procedures, mostly with synthetic sling (82%). Patients were assessed before surgery and at least 1 month postoperatively using the ICIQ-SF in its translated and validated Portuguese version. Patients also underwent pre-operative urodynamic tests, Stamey incontinence grading and pad usage assessments. After surgery, patients underwent stress tests, Stamey incontinence grading and pad usage assessments. RESULTS: The mean age was 57.2 (+/- 11.6) years and the mean duration of follow-up was 7.2 months (+/- 4.5). Objective parameters such as urodynamic tests (by means of VLPP) and pad usage had significant correlation with changes in post-treatment scores on the ICIQ-SF (p = 0.0062 and p < 0.0001 respectively). The responsiveness expressed in terms of standardized effect sizes (SES) and standardized response means (SRM) was large for both questionnaires (p < 0.0001). CONCLUSION: The results showed high responsiveness (large effect sizes I and II) for the Portuguese version of the ICIQ-SF, indicating that this instrument is suitable for measuring outcomes in clinical trials for Brazilian patients with stress urinary incontinence.

Multiple-signaling pathways are involved in the inhibitory effects of galangin on urinary bladder contractility.

AIMS: Flavonoids comprise a large group of natural polyphenolic compounds, which possess a wide spectrum of physiological and pharmacological effects. Recently, the flavonoid galangin was found to modulate smooth muscle contractility. The aim of the present study was to investigate the mechanism of actions of galangin on pig bladder smooth muscle and to characterize its potential as an alternative inhibitor of bladder smooth muscle contraction. MATERIALS AND METHODS: Strips of pig detrusor muscle were mounted in separate 6-ml organ baths containing Krebs solution. The contractile response to carbachol (10(-8)-10(-4)M), potassium (2x10(-2)-10(-1)M), and electrical field stimulation-EFS (2-32 Hz) were determined before and after the addition of galangin (3x10(-5)M). The contractile responses to carbachol in calcium-free Krebs' solution plus EGTA and L-type channel blocker were determined in the absence and presence of the flavonoid. Furthermore, the effect of galangin was also evaluated after the administration in the bath of a number of antagonists/inhibitors including a combination of propranolol, phentolamine, capsazepine, and verapamil. Student's t-test and one factor ANOVA were used to determine the statistical significance of the effects. RESULTS: Galangin inhibited the maximal contractile response to carbachol and potassium by 57.41% (P<0.01) and 33.52% (P<0.05), respectively. The maximum force of the carbachol-evoked contractions in calcium-free solution after incubation with galangin was 32% of the maximum initial force (Emax.initial: 5.8387+/-0.72 mN, Emax.Galangin: 1.9157+/-0.30 mN, P<0.01). The maximal contractile responses to EFS at 2, 4, 8, 16, and 32 Hz were reduced, compared to control, by 91.61% (P<0.01), 79.46% (P<0.01), 70.54% (P<0.01), 61.10% (P<0.01), and 9.8% (P>0.05), respectively. The inhibitory effect of galangin was unaffected by a combination of propranolol, phentolamine, and capsazepine (P>0.05). However, when verapamil was added to the medium, the inhibitory effects of galangin were partially blocked. CONCLUSIONS: Galangin, at high concentrations, exerts an inhibitory effect on pig bladder smooth muscle contractility through the inhibition of calcium influx and the modulation of intracellular calcium movement. Furthermore, we have demonstrated that the inhibitory effect of galangin involves, at least in part, L-type calcium channels pathways.

The Ibero-American experience with a re-adjustable minimally invasive sling.

OBJECTIVE: To report our experience with the Safyre (Promedon, Cordoba, Argentina), a new re-adjustable and minimally invasive sling for treating stress urinary incontinence (SUI), which combines the efficacy of slings with re-adjustability. PATIENTS AND METHODS: In all, 126 consecutive patients with a clinical and urodynamic diagnosis of SUI had a Safyre sling procedure (mean age 63 years, range 40-71). Seventy-six patients (60%) presented after previous failed anti-incontinence procedures; all had a physical and clinical examination, a stress test, urodynamic study and assessment of pad use before the surgery. All the patients presented with symptoms of SUI and 37 (29%) also reported mild urgency. RESULTS: The mean (range) follow-up was 18 (12-36) months, and the mean operative duration 25 min. Dystopia was repaired whenever necessary during the same procedure. The mean hospital stay was 24 h. In three implants (2%) the bladder was perforated. After surgery 26 patients (21%) developed urgency symptoms; during the follow-up 116 (92%) were continent, three (2%) reported an improvement and seven (6%) were dissatisfied. CONCLUSION: The Safyre is a safe and quick procedure that allows for postoperative readjustment; this technique may be an attractive alternative if the good results obtained so far prove to be durable.

Readjustable transobturator sling: a novel sling procedure for male urinary incontinence.

Post-prostatectomy incontinence remains a significant problem for both patients and urologists. We report a case and the surgical technique of successful sling in the treatment of post-prostatectomy urinary incontinence. Sling surgery was performed on a 69-year-old male patient with severe urinary incontinence (6 pads/day) following radical prostatectomy. The procedure was conducted through the transobturator approach using a sling with a silicone foam pad to protect the urethra. At the 7-month follow-up the patient is using only 1 pad/day. We consider this operation an alternative to artificial urinary sphincter in cases of male sphincter incontinence.

Concurrent validity, internal consistency and responsiveness of the portuguese version of the king's health questionnaire (KHQ) in women after stress urinary incontinence surgery

OBJECTIVE: To evaluate the concurrent validity, internal consistency and responsiveness of King's Health Questionnaire (KHQ) in patients who underwent sling procedures for the treatment of stress urinary incontinence. MATERIALS AND METHODS: We performed a prospective open label multicenter study in 4 tertiary referral centers. Sixty-eight female patients were enrolled with urodynamically diagnosed urinary stress incontinence. Patients were treated using surgical procedures, mostly (73 percent) with the synthetic sling procedure, which has been considered one of the gold standard methods for the treatment of urinary incontinence. The patients were assessed before and after one month of postoperative follow up, using the KHQ in its validated Portuguese version. Patients also underwent preoperative urodynamic test, Stamey incontinence grading, pad usage and the assessment of number of pads used per day. After surgery, patients underwent stress test, Stamey incontinence grading pad usage and the assessment of number of pads used per day. RESULTS: The concurrent validity showed good correlations in some domains of KHQ to clinical parameters. The internal consistency was higher after treatment compared to preoperative values. Objective parameters, such as pad usage and the assessment of number of pads used per day, had significant correlation with changes in post-treatment scores on KHQ. The responsiveness expressed in terms of standardized effect size (SES) and standardized response mean (SRM) was large. CONCLUSION: The results showed moderate concurrent validity, strong internal consistency and high responsiveness for KHQ, indicating that it is suitable for measuring outcomes in clinical trials among female patients with stress urinary incontinence.

Resiniferatoxin for detrusor instability refractory to anticholinergics

PURPOSE: We have evaluated the clinical and urodynamic effects of intravesical instillation of resiniferatoxin in patients with idiopathic detrusor instability refractory to anticholinergics. MATERIALS AND METHODS: There were 30 women, median age 56 years old with detrusor instability for over 6 months and a history of anticholinergic use with no response or intolerable collateral effects. A 50 nM solution of resiniferatoxin was prepared for intravesical instillation. All patients were evaluated for urinary symptoms, as well as for urodynamic assessments before and 30 days after instillation. Tolerability was analyzed during the instillation. RESULTS: A clinical improvement was observed in 30 percent of the patients with urinary urgency and in 33 percent of the patients with urge-incontinence. The mean maximum cystometric capacity before application was 303.9 ± 78.9 and after application 341 ± 84.6. No significant difference was observed (p = 0.585). The mean maximum amplitude of the contractions diminished from 47.86 ± 29.64 to 38.72 ± 30.77 (p = 0.002). CONCLUSIONS: Resiniferatoxin, in this concentration, proved to be useful in a small percentage of patients regarding clinical detrusor instability. Maximum amplitude of the involuntary contractions was significantly reduced and in 33 percent patients the involuntary contractions disappeared. Further studies with different concentrations are recommended.

Safyreã: a readjustable minimally invasive sling for female urinary stress incontinence

INTRODUCTION: SAFIRE TM is a readjustable and minimally invasive sling for the treatment of stress urinary incontinence (SUI). It is as a pubovaginal sling placed in the medial third of the urethra. The initial experience is described. MATERIALS AND METHODS: Forty-five patients (mean age = 59 years) underwent a SAFYRE TM implant to treat SUI. Physical examination and urodynamic study were performed before surgery. All patients presented symptoms of SUI and 20 percent also reported mild urgency. Approximately 60 percent of this group had a previously failed anti-incontinence procedure. Urethral hypermobility was diagnosed in 40 percent of the patients and intrinsic sphincter deficiency (ISD) in 60 percent of the cases. RESULTS: The average follow up period was 10 months. The mean operative time was 20 minutes. Dystopia repair was performed whenever necessary, during the same procedure. The average hospital stay was 24 hours. In 11 percent of the implants, bladder perforation occurred. During the postoperative period, 9 patients (20 percent) developed transient urgency symptoms. During the initial follow up period, 90 percent were found to be continent, 3 percent reported an improvement and 7 percent were unchanged. CONCLUSION: SAFYRE TM is a safe and quick procedure that allows postoperative readjustment. This technique may be an attractive alternative in the management of SUI, should the good result obtained so far prove to be long lasting.

Is the anterior vaginal wall sling a good alternative for intrinsic sphincteric insufficiency?

OBJECTIVES: We present our experience with the anterior vaginal wall sling, in the treatment of patients with stress urinary incontinence (SUI) due to urethral intrinsic sphincteric deficiency. MATERIAL AND METHODS: Forty-five women (mean age 53.4 years) with urodynamically proven intrinsic sphincteric deficiency (Valsalva Leak Point Pressure below 60cm H(2)O) were studied, prospectively. Coexisting bladder neck hypermobility was assessed using transperineal ultrasound. Patients with severe pelvic prolapse (grade 3 or 4) were excluded. Multivariable logistic regression was used to identify the variables that influenced the outcome (statistical significance was established for p<0.05). Follow-up ranged from 26 to 61 months (mean 40 months). RESULTS: Complete SUI cure was achieved in 14 women (31.1%) and 17 other women (37.8%) described SUI improvement and were satisfied with the outcome. Statistical analysis showed that factors such as age below 35 years (p=0.0251), and preoperative bladder neck hypermobility (p=0.0176), were strongly related to postoperative continence. CONCLUSIONS: We concluded that the vaginal wall sling has a high rate of failure in the treatment of patients with intrinsic sphincteric deficiency. This technique should not be proposed if hypermobility is not associated, especially in the case of elderly patients.

Tension-free vaginal tape (TVT): minimally invasive technique for stress urinary incontinence (SUI).

OBJECTIVE: The procedure o tension-free vaginal tape (TVT) was recently introduced in the therapeutic armamentarium of stress urinary incontinence (SUI). It is a pubovaginal sling applied in mid-urethra. The authors describe their experience with this technique. MATERIALS AND METHODS: During the period of May, 1999 to March, 2001, 110 patients (median age=53 years) were submitted to TVT implant for the treatment of stress urinary incontinence. Clinical exam and urodynamic studies were performed previously to surgery. All patients referred symptoms consistent with stress incontinence, and 35.7% complained of associated voiding urgency. Sixty-eight percent of the group reported previous continence procedure. Urethral hypermobility was diagnosed in 42% of patients (mean Valsalva leak point pressure under median effort of 110 cmH(2)O), and 58% had intrinsic sphincter deficiency (mean Valsalva leak point pressure under effort of 55 cmH(2)O). RESULTS: Mean patient follow-up was 18 months. Ninety-two percent of the patients were submitted to anesthetic blockade and 8% to local anesthesia. Mean length of the procedure was 30 minutes. Dystopy correction, when present, was performed in the same procedure. Mean hospital stay was 24 hours. There was bladder perforation in 13% of cases of TVT. There was no urethral or vaginal erosion. Twenty patients (18%) developed urgency symptoms during post-operative period, and 5 (4.5%) presented urge incontinence. During this follow-up period, 81% remained continent, 9% referred improvement of the symptoms compared to before the procedure and 10% were not satisfied. CONCLUSION: Our data allow us to conclude that TVT procedure is safe, rapid and promoting adequate levels of continence in mean term.
