Presentamos un caso tratado con cabestrillo de fascia lata, describiendo la técnica y evolución.

ABSTRACT Stress urinary incontinence is common in women from middle adulthood onwards. The most frequent technique to treat these cases is the synthetic sling. However, the autologous sling has good results comparable with the synthetic material in the various studies published. We present a case treated with fascia lata sling, describing the technique and evolution.

Clinical and Urodynamic results of the Argus T® sling in moderate and severe male stress urinary incontinence after radical prostatectomy - a 5 year prospective study

ABSTRACT Purpose: Sling as a therapeutic option for male stress urinary incontinence (SUI) has been reviewed in the last two decades, as it is a relatively simpliest surgery compared to artificial urinary sphincter and has the ability to modulate urethral compression. This study aims to evaluate the efficacy, rate of complications, quality of life and the effects on bladder emptying of the Argus T® compressive and ajustable sling in moderate and severe male SUI treatment. Materials and Methods: Men eligible for stress urinary incontinence treatment after radical prostatectomy were recruited and prospectively evaluated, from March 2010 to November 2016. It was selected outpatient men with moderate and severe SUI, after 12 months of radical prostatectomy, who have failed conservative treatment. All patients had a complete clinical and urodynamic pre and post treatment evaluation, by means of clinical history, physical examination, urine culture, 1-hour pad test and ICIq-SF questionnaire. The UDS was performed after 12, 18 and 24 months postoperatively. Results: Thirty-seven men underwent sling surgery, 19 patients (51.4%) with moderate and 18 (48.6%) with severe SUI. The minimum follow-up time was 5 years. Overall, we had a success rate of 56.7% at 60 months follow-up. After surgery, we did not observe significant changes in the urodynamic parameters evaluated during the follow-up. No patient had urodynamic bladder outlet obstruction (BOO) after sling implantation. Readjustment of the Argus T® sling was performed in 16 (41%) of the patients and 51% of the patients reported some adverse event. Conclusion: We demonstrate a long-term efficacy and safety of Sling Argus T® as an alternative to moderate and severe male SUI treatment. Furthermore, in our study bulbar urethra compression does not lead to bladder outlet obstruction.

Incontinence outcomes in women undergoing retropubic mid-urethral sling: a retrospective cohort study comparing Safyre™ and handmade sling

ABSTRACT Purpose This study examined and compared efficacy, safety, satisfaction, and complications of the retropubic Safyre™ sling and a retropubic hand-made synthetic sling (HMS) in a short-, mid- and long-term follow-up. Methods We retrospectively reviewed a prospectively maintained database of women who underwent Safyre™ or HMS between March 7ths 2005 and December 27ths, 2017. Patients had first assessment (7-10 days), second (40-45 days), and third (sixth month) postoperatively. Between September and December 2018, patients who completed at least one year of surgery, received a telephone call. Follow-up compared quartiles of follow-up time to determine complications (Clavien-Dindo), success rates (International Consultation on Incontinence Modular Questionnaire for Urinary Incontinence Short Form - ICIQ-UI SF), and patient satisfaction. Results Three hundred fifty-one patients underwent surgery and 221 (63%) were evaluated after a median of 78.47 (± 38.69) months, 125 (55%) in the HMS, and 96 (45%) in the Safyre™ group. Higher intraoperative bladder injury was observed with Safyre™ (0% vs. 4.2%, p=0.034), and a tendency for urinary retention, requiring indwelling urinary catheter over 24 hours (2.4% vs. 8.3%, p=0.061). Both HMS (p<0.001) and Safyre™ (p<0.001) presented improvements on ICIQ-UI SF. There were no differences in satisfaction, subjective cure rates, ICIQ-UI SF, or complications between groups. Conclusions Both HMS and Safyre™ have similar satisfaction and subjective cure rates, with marked ICIQ-UI SF score improvement. Higher rates of intraoperative bladder injury were seen in patients who received Safyre™ retropubic sling.

Standing cough test stratification of moderate male stress urinary incontinence

ABSTRACT Purpose: Patient-reported history of pads per day (PPD) is widely recognized as a fundamental element of decision-making for anti-incontinence procedures. We hypothesize that SUI severity is often underestimated among men with moderate SUI. We sought to compare patient history of incontinence severity versus objective in-office physical examination findings. Materials and Methods: We retrospectively reviewed our single-surgeon male SUI surgical database from 2007-2019. We excluded patients with incomplete preoperative or postoperative data and those who reported either mild or severe SUI, thus having more straightforward surgical counseling. For men reported to have moderate SUI, we determined the frequency of upgrading SUI severity by recording the results of an in-office standing cough test (SCT) using the Male Stress Incontinence Grading Scale (MSIGS). The correlation of MSIGS with sling success rate was calculated. Failure was defined as >1 PPD usage or need for additional incontinence procedure. Results: Among 233 patients with reported moderate SUI (2-3 PPD), 89 (38%) had MSIGS 3-4 on SCT, indicating severe SUI. Among patients with 2-3 PPD preoperatively, sling success rates were significantly higher for patients with MSIGS 0-2 (76/116, 64%) compared to MSIGS 3-4 (6/18, 33%) (p <0.01). Conclusions: Many men with self-reported history of moderate SUI actually present severe SUI observed on SCT. The SCT is a useful tool to stratify moderate SUI patients to more accurately predict sling success.

Can platelet-rich plasma coating improve polypropylene mesh integration? An immunohistochemical analysis in rabbits

ABSTRACT Purpose: Despite high success rates in the treatment of urinary incontinence, complications related to the use of polypropylene (PP) meshes are still a concern, especially in vaginal prolapses surgeries. The objective of this study was to assess the effect of autologous platelet-rich plasma (PRP) coating on the integration of PP meshes implanted in the vaginal submucosa of rabbits. Materials and Methods: Thirty adult New Zealand rabbits were randomly divided into two groups (n=15): PP, implanted with conventional PP meshes; and PRP, implanted with autologous PRP coated PP meshes. Animals in both groups (n=5) were euthanized at 7, 30 and 90 days postoperatively, the vaginas extracted and sent to immunohistochemical analysis for the assessment of the pro-inflammatory agent TNF-α, anti-inflammatory agents TGF-β and IL-13, collagen metabolism marker MMP-2, and angiogenesis marker CD-31. AxioVision™ image analysis was used for the calculation of the immunoreactive area and density. Statistical analysis was performed with ANOVA followed by Tukey test (p <0.05). Results: Animals in the PRP group showed significantly increased expression of the angiogenesis agent CD-31 at all experimental times when compared to the PP group (p <0.0001). However, no differences concerning the expression of the other markers were observed between the groups. Conclusion: The addition of autologous PRP gel to PP meshes can be simply and safely achieved and seems to have a positive effect on implantation site angiogenesis. Further investigations are required to ascertain PPR coated meshes clinical efficacy in prolapses and stress urinary incontinence surgeries.

Comparison of 2 single incision slings on the vagina in an ovine model.

BACKGROUND: Stress urinary incontinence carries a significant healthcare burden for women worldwide. Single incision slings are minimally invasive mesh devices designed to treat stress urinary incontinence. For prolapse repair, meshes with higher porosity and lower structural stiffness have been associated with improved outcomes. OBJECTIVE: In this study, we compared the higher stiffness, lower porosity Altis sling with the lower stiffness, higher porosity Solyx sling in an ovine model. We hypothesized that SIS-B would have a negative impact on the host response. STUDY DESIGN: A total of Altis and Solyx single incision slings were implanted suburethrally into sheep according to the manufacturer's instructions on minimal tension. The mesh-urethral-vaginal complex and adjacent ungrafted vagina (no mesh control) were harvested en bloc at 3 months. Masson's trichrome and picrosirius red staining of 6 µm thin sections was performed to measure interfiber distance and tissue integration. Smooth muscle contractility to a 120 mM KCl stimulus was performed in an organ bath to measure myofiber-driven contractions. Standard biochemical assays were used to quantify glycosaminoglycan, total collagen, and elastin content, and collagen subtypes. Bending stiffness was performed in response to a uniaxial force to define susceptibility to folding/buckling. Statistical analysis was performed using Mann-Whitney, Gabriel's pairwise post hoc, Wilcoxon matched-pairs, and chi-square tests. RESULTS: The animals had similar ages (3-5 years), parity (multiparous), and weights (45-72 kg). Trichrome cross sections showed that the Altis sling buckled in a "C" or "S" shape in most samples (8 of 11), whereas buckling after Solyx sling implantation was observed in only a single sample (1 of 13; P=.004). Tissue integration, as measured by the presence of collagen or smooth muscle between the mesh fibers on trichrome 4× imaging, was increased in samples implanted with the Solyx sling compared with the Altis sling (P<.05). Total collagen content decreased significantly with both products when compared with the ungrafted vagina consistent with stress shielding. There was no difference in the 2 groups with regard to glycosaminoglycan or elastin content. The Altis sling mesh tissue complex demonstrated significantly higher amounts of both collagen types I and III than the Solyx sling-implanted tissue and the ungrafted control. Smooth muscle contractility in response to 120 mM KCl was decreased after implantation of both slings compared with the sham (P=.011 and P<.01), with no difference between mesh types (P=.099). Bending stiffness in the Altis sling was more than 4 times lower than in the Solyx, indicating an increased propensity to buckle (0.0186 vs 0.0883). CONCLUSION: The structurally stiffer Altis sling had decreased tissue integration and increased propensity to buckle after implantation. Increased collagen types I and III after the implantation of this device suggests that these changes may be associated with a fibrotic response. In contrast, the Solyx sling largely maintained a flat configuration and had improved tissue integration. The deformation of the Altis sling is not an intended effect and is likely caused by its lower bending stiffness. Both meshes induced a decrease in collagen content and smooth muscle contractility similar to previous findings for prolapse meshes and consistent with stress shielding. The long-term impact of buckling warrants further investigation.

Obesity as a risk factor for poor outcomes after sling surgery in women with stress urinary incontinence: A systematic review and meta-analysis.

PURPOSE: Obesity is one of the main risk factors for stress urinary incontinence (SUI) and has also been associated with worse surgical outcomes. However, the literature is heterogeneous and inconclusive. The goal of this study was to perform a systematic review and meta-analysis to evaluate cure rates and perioperative complications in obese women. MATERIALS AND METHODS: A literature search of OVID, MEDNAR, Embase, Scopus, Web of Science, PubMed, and CENTRAL databases was conducted. Randomized controlled trials comparing cure rates and failure of treatment in normal and obese patients, who underwent mid-urethral sling surgery, were identified. A systematic review of subjective and objective cure rates, and complications was performed. Meta-analyses of dichotomous data under the random-effects model were applied using Review Manager 5.3. Nonrandomized comparative studies and gray literature were excluded. RESULTS: A total of 219 studies were identified. Four randomized controlled trials were included for evaluation. The risk of bias evaluation was performed according to the Cochrane Handbook for Systematic Reviews of Interventions. One study was excluded due to missing data on the outcomes. Patients were stratified according to their body mass index as obese (>30 kg/m2 ) and nonobese (<30 kg/m2 ). Complications could not be meta-analyzed. The meta-analysis of subjective (risk ratio [RR] = 1.69 [95% confidence interval [CI]: 1.32-2.16]) and objective (RR = 1.62 [95% CI: 1.26-2.07]) cure rates disfavored obese women. CONCLUSIONS: This meta-analysis shows that obesity is a risk factor for the nonsuccessful treatment of SUI with tension-free mid-urethral sling. Differences in regards to the surgical approach and its association with obesity could not be established with the current evidence.

Underactive Bladder and Bladder Outlet Procedures in Women.

PURPOSE OF REVIEW: This review outlines current options for women suffering from both stress urinary incontinence (SUI) and underactive bladder (UAB). This is often a challenging patient population; however, many treatment options are available including behavioral, pharmacologic, and surgical. Therapies can be divided into those specifically targeting either the bladder or the bladder outlet. RECENT FINDINGS: For patients with SUI and UAB, several clinical trials have helped to formulate current guidelines. Also, a number of novel techniques and therapeutic agents are currently under investigation. Current surgical treatments frequently employed for SUI include midurethral slings and urethral bulking agents. In contrast, the current treatments for UAB are limited to either sacral neuromodulation in women with Fowlers syndrome or in the majority, clean intermittent catheterization. Recent studies have investigated the use of adjustable urethral slings and novel modes of neuromodulation with varying degrees of success. SUMMARY: Choosing the best treatment plan for SUI combined with UAB involves a thorough understanding of a patient's preferences and goals. Fortunately, women have many options that can significantly benefit their quality of life.

Transobturator suburethral tape versus suburethral tape placement in female stress urinary incontinence / Cinta suburetral versus cinta transobsturatriz en el tratamiento de la incontinencia urinaria de esfuerzo femenina

ABSTRACT Introduction : The surgical management of stress urinary incontinence uses the transobturator tape (TOT) technique since 2006. We present a study applying the suburethral tape as a better alternative that does not require the TOT needle. Objective : To demonstrate the advantages of the suburethral tape placement technique over the transobturator tape technique in the surgical treatment of stress urinary incontinence. Methods : Observational comparative study using the non- invasive suburethral tape placement versus the transobturator tape technique. Results : Fifty patients were treated with TOT for stress urinary incontinence and other 50 patients were managed with suburethral tape placement (UTP) in the previous shift the same day or the preceding day. The TOT patients were 56 years old on average, and time of the procedure was 18 minutes on average. Complications included pain in the inguinal area (13 cases), mesh extrusion (2 cases), and suture dehiscence of anterior colporrhaphy, presence of left inguinoperineal granuloma due to mesh reaction and bruising in the left obturator area (one case of each). The 50 patients treated with UTP were 56 years old on average, operating time was 7 minutes on average, and there were no complications. The cost of the TOT kit was about US$ 1 000.00, and the suburethral tape cost was US$ 50.00. Conclusions : In this study of stress urinary incontinence treatment, the suburethral tape technique was safer than the transobturator tape technique and had a lower cost.

RESUMEN Introducción . Entre los tratamientos quirúrgicos de la incontinencia urinaria de esfuerzo se emplea la técnica de la cinta transobturatriz (TOT, por sus siglas en inglés) desde el 2006 hasta la actualidad. Se presenta un estudio con la aplicación de la cinta uretral (UTP, por sus siglas en inglés) como mejor alternativa al no usar la aguja del TOT. Objetivo . Demostrar las ventajas de la aplicación de la cinta suburetral versus la cinta transobturatriz en el tratamiento quirúrgico de la incontinencia urinaria de esfuerzo. Métodos . Estudio observacional, comparativo con la técnica no invasiva empleando cinta suburetral versus la técnica de la cinta transobturatriz. Resultados . Se evaluó 50 pacientes intervenidas con TOT, quienes precedieron un turno el mismo día o el día precedente a las pacientes operadas con la cinta uretral. El promedio de edad fue 56 años y el tiempo promedio del procedimiento fue 18 minutos. Las complicaciones consistieron en dolor en la zona inguinal (13 casos), extrusión de malla (2 casos) y, una de cada caso, dehiscencia de sutura de la colpoporrafia anterior, presencia de granuloma inguinoperineal izquierdo por reacción a la malla, hematoma en zona obturatriz izquierda. En los 50 casos tratados con cinta suburetral, el promedio de edad fue 56 años, el tiempo operatorio 7 minutos y no existió complicación alguna. El costo del kit de la TOT fue alrededor de US$ 1 000.00; la cinta suburetral costó US$ 50.00. Conclusiones . En la presente serie de manejo de la incontinencia urinaria de esfuerzo, la técnica de la cinta suburetral resultó más segura que la técnica de la cinta transobturatriz y fue de menor costo.

Effects of the transobturator tape procedure on overactive bladder symptoms and quality of life: a prospective study.

INTRODUCTION: This study aimed to evaluate the effects of transobturator tape (TOT) on overactive bladder (OAB) symptoms and quality of life. MATERIALS AND METHODS: Patients with stress-predominant mixed urinary incontinence (MUI) who had undergone TOT procedures were considered candidates for this research. Preoperative assessment included anamnesis, pelvic examination, cough stress test (CST), and validated symptom severity and quality of life (QoL) questionnaires. The primary outcome, improvement and cure rates of OAB symptoms were determined based on the patient's baseline scores in symptom-related questions in OAB-V8. Secondary outcomes included the success rates of SUI, changes in the QoL score and patient satisfaction rates. RESULTS: A total of 104 patients were included in the study. Sixty-two patients underwent TOT placement alone, and 42 patients underwent TOT placement along with prolapse surgery. The mean follow-up period of the patients was 30.47 months range: 13-52 months. At the fi rst-year follow-up, 52 patients (50.0%) and 59 patients (56.7%) reported cure in preoperative urgency and urgency incontinence, respectively. The objective and subjective cure rates were 96.2% and 56.7%, respectively. A total of 80.7% of the cases had a 15-point improvement in QoL scores. CONCLUSIONS: MUS is not only a gold standard treatment in SUI but also presents as a promising treatment modality in stress-dominant MUI. Although the improvement rates of OAB symptoms signifi cantly decrease over time, QoL and patient satisfaction rates remain higher than any other treatment in this patient group at the third-year follow-up.

The association between personal history and the outcomes of transobturator sling surgery

SUMMARY OBJECTIVE: This study aims to verify the association between risk factors for the onset of SUI and transobturator suburethral sling surgical treatment outcomes. PATIENTS AND METHODS: A retrospective study was conducted with 57 patients operated by the Pelvic Floor Surgery Service. Demographic data were compiled from the sample, the body mass index (BMI) was calculated, and the patients were divided according to the response to the surgical treatment. RESULTS: A total of 77.2% of the sample was cured or improved after surgical treatment. Out of the total sample, 75.4% of the women were postmenopausal, and 73.7% denied current or past smoking. The median age was 61 years, the median number of births was 4.0, the median BMI was 28.6 kg/m2, and 50.9% of the sample was classified as pre-obese. BMI, menopausal status, age, smoking, and sexual activity were not factors associated with the surgical outcome. However, parity equal to or greater than 5 was associated with worse postoperative results (p = 0.004). CONCLUSIONS: among risk factors associated with the emergence of SUI, only parity greater than 4 showed a negative impact on transobturator sling surgery outcomes.

RESUMO OBJETIVO: O estudo pretende verificar a associação entre fatores de risco relacionados ao surgimento da IUE com resultado do tratamento cirúrgico com sling suburetral transobturador. PACIENTES E MÉTODOS: Foi realizado estudo retrospectivo com 57 pacientes operadas pelo serviço de Cirurgia do Assoalho Pélvico da FMJ. Foram compilados dados demográficos da amostra, calculado o índice de massa corpórea (IMC) e as pacientes foram divididas de acordo com a resposta ao tratamento cirúrgico. RESULTADOS: 77,2% da amostra apresentou-se curada ou melhorada após o tratamento cirúrgico, 75,4% das mulheres se encontravam na pós-menopausa e 73,7% negaram tabagismo atual ou passado. A mediana de idade foi de 61 anos, a mediana do número de partos foi de 4,0 e a mediana do IMC foi de 28,6 kg/m2; 50,9% da amostra foi classificada como pré-obesa. O IMC, o status menopausal, a idade, o tabagismo e a manutenção da atividade sexual não foram fatores associados ao resultado cirúrgico. Porém, a paridade igual ou superior a 5 associou-se a piores resultados pós-operatórios (p=0,004). CONCLUSÕES: Entre os fatores de risco associados ao surgimento da IUE, apenas a paridade maior que 4 influenciou negativamente as taxas de melhora após cirurgia de sling transobturador.

Implant of ATOMS® system for the treatment of postoperative male stress urinary incontinence: results of a single centre

ABSTRACT Purpose: The aim of our study is to evaluate the efficacy and safety of ATOMS® system for the treatment of postoperative male stress urinary incontinence (SUI). Materials and methods: We retrospectively evaluated all patients treated at our institution for postoperative male SUI with ATOMS® implant. We excluded patients with low bladder compliance (< 20 mL / cmH2O), uncontrolled detrusor overactivity, detrusor underactivity (BCI < 100), urethral or bladder neck stricture and low cystometric capacity (< 200 mL). Results: From October 2014 to July 2017 we treated 52 patients, mean age 73.6 years. Most of them (92.3%) had undergone radical prostatectomy, 3.85% simple open prostatectomy, 3.85% TURP; 28.8% of patients had undergone urethral surgery, 11.5% adjuvant radiotherapy; 57.7% had already undergone surgical treatment for urinary incontinence. The average24 hours pad test was 411.6 g (180 - 1100). The mean follow-up was 20.1 months (8.1 - 41.5) 30.8% of patients were dry, 59.6% improved ≥ 50%, 7.7% improved < 50% and 1.9% unchanged. In total 73.1% reached social continence. There was a significant reduction of the 24 hours pad test and ICIQ - UI SF scores (p < 0.01). In the postoperative follow-up we detected complications in 8 patients (19%): 5 cases of displacement of the scrotal port, in 2 cases catheterization difficulties, one case of epididimitis and concomitant superficial wound infection; no prosthesis infection, nor explants. Radiotherapy, previous urethral surgery,previous incontinence surgery were not statistically related to social continence rates (p 0.65;p 0.11;p 0.11). Conclusions: The ATOMS® system is an effective and safe surgical treatment of mild and moderate male postoperative SUI with durable results in the short term.

The average24 hours pad test was 411.6 g (180 - 1100). The mean follow-up was 20.1 months (8.1 - 41.5) 30.8% of patients were dry, 59.6% improved ≥ 50%, 7.7% improved < 50% and 1.9% unchanged. In total 73.1% reached social continence. There was a significant reduction of the 24 hours pad test and ICIQ - UI SF scores (p < 0.01). In the postoperative follow-up we detected complications in 8 patients (19%): 5 cases of displacement of the scrotal port, in 2 cases catheterization difficulties, one case of epididimitis and concomitant superficial wound infection; no prosthesis infection, nor explants. Radiotherapy, previous urethral surgery,previous incontinence surgery were not statistically related to social continence rates (p 0.65;p 0.11;p 0.11). CONCLUSIONS: The ATOMS® system is an effective and safe surgical treatment of mild and moderate male postoperative SUI with durable results in the short term.

Adjustable sling for the treatment of post-prostatectomy urinary incontinence: systematic review and meta-analysis / Implante de sling ajustável no tratamento da incontinência urinária pós-prostatectomia: revisão sistemática e meta-análise

ABSTRACT Urinary incontinence after prostatectomy has a significant negative impact on the quality of life of the patient. The surgical treatment includes several models of male slings, such as adjustable slings. The objective of this study was to evaluate the effectiveness and safety of adjustable sling in the treatment of post-prostatectomy urinary incontinence. This is a systematic review of literature. The following electronic databases were searched until January 2018: PubMed®, Embase, CENTRAL and LILACS. The keywords used in the search strategies were: "prostatectomy" [Mesh], "urinary incontinence" [Mesh] and "suburethral slings" [Mesh]. Randomized clinical trials and observational studies, with or without Control Group, and follow-up of more than 12 months were included. Only one randomized study with high risk of bias was included and it concluded the effectiveness equivalence between adjustable and non-adjustable slings. All other studies were cases series with patients of varying levels of incontinence intensity and history of pelvic radiation therapy and previous surgeries. The meta-analysis for 0 pad in 24 hours demonstrated an effectiveness of 53%. For the 0 to 1 pad test in 24 hours, the meta-analysis resulted in an effectiveness of 69%. Risk factors for surgery failure include prior radiation, severity of post-prostatectomy urinary incontinence, and previous surgeries. The meta-analysis of the extrusion rate was 9.8% and the most commonly reported adverse effects were pain and local infection. Evidence of low quality indicates that adjustable slings are effective for treating post-prostatectomy urinary incontinence, with frequency of adverse events similar to the surgical option considered gold standard (the artificial urinary sphincter implant).

RESUMO A incontinência urinária pós-prostatectomia tem importante impacto negativo na qualidade de vida do portador. O tratamento cirúrgico inclui slings masculinos e, entre os diversos modelos, os slings ajustáveis. O objetivo deste estudo foi avaliar a efetividade e a segurança do sling ajustável no tratamento da incontinência urinária pós-prostatectomia. Trata-se de revisão sistemática de literatura. Foram pesquisadas as seguintes bases de dados eletrônicas até janeiro de 2018: PubMed®, Embase, CENTRAL e LILACS. As palavras-chaves utilizadas nas estratégias de busca foram: "prostatectomy" [Mesh], "urinary incontinence" [Mesh] e "suburethral slings" [Mesh]. Foram incluídos ensaios clínicos randomizados e estudos observacionais controlados ou não com seguimento maior que 12 meses. Apenas um estudo randomizado com alto risco de viés foi localizado e concluiu a equivalência de efetividade de slings ajustáveis e não ajustáveis. Todos os outros estudos foram série de casos com pacientes de variados níveis de intensidade da incontinência e histórico de radioterapia pélvica e cirurgias prévias. A metanálise para 0 pad em 24 horas demonstrou efetividade de 53%. Para o desfecho 0 a 1 pad em 24 horas, a metanálise resultou em efetividade de 69%. Os fatores de risco para insucesso da cirurgia incluem radiação prévia, gravidade da incontinência urinária pós-prostatectomia e cirurgias anteriores. A metanálise da taxa de extrusão foi de 9,8%, e os efeitos adversos mais relatados foram dor e infecção local. Evidências de baixa qualidade indicam que os slings ajustáveis são efetivos para o tratamento da incontinência urinária pós-prostatectomia, com frequência de eventos adversos semelhantes à opção cirúrgica considerada padrão-ouro (o implante de esfíncter urinário artificial).

Evaluation of urodynamic parameters after sling surgery in men with post-prostatectomy urinary incontinence

ABSTRACT Objective: To evaluate urodynamic alterations after sub-urethral sling surgery (SSU) in patients with post-prostatectomy urinary incontinence (PPUI). Materials and Methods: We evaluated data of 22 patients submitted to radical prosta- tectomy (RP) or transurethral resection of prostate (TURP) that presented post-surgical urinary incontinence and were treated with SSU implant in a pilot study previously performed in our institution. Methods: Those patients with PPUI were evaluated by urodynamic exam (UD) before and after surgery, and the parameters were compared, including uroflow, cystometry and micturition study. Exclusion criteria included patients without pre-operatory urodynamic study, those with urethral stenosis, those not healed of prostate cancer, pa- tients without clinical conditions to be submitted to urodynamic study and those with severe neurological diseases or that refused to sign the consent form. Results were analyzed statistically by Fisher, Wilcoxon or Mann-Whitney tests. Results: During free uroflow, none parameters showed any statistical significant differ- ences. During cystometry, there were also no statistical differences and the same was observed at pressure versus flow study; the exception was at maximal flow detrusor pressure (PdetQmax), that was lower at post-operatory (p=0.028). In relation to the presence of urinary dysfunctions associated to PPUI, we observed a significant reduc- tion of detrusor overactivity (p=0.035) in relation to pre-operatory period. Conclusion: SSU surgery significantly reduced detrusor overactivity and PdetQMax; however, there were no alterations of other evaluated urodynamic parameters.
