Pelvic floor muscle training protocol for stress urinary incontinence in women: A systematic review / Protocolo de treino dos músculos do pavimento pélvico em mulheres com incontinência urinária de esforço: revisão sistemática

Summary Introduction: Strengthening exercises for pelvic floor muscles (SEPFM) are considered the first approach in the treatment of stress urinary incontinence (SUI). Nevertheless, there is no evidence about training parameters. Objective: To identify the protocol and/or most effective training parameters in the treatment of female SUI. Method: A literature research was conducted in the PubMed, Cochrane Library, PEDro, Web of Science and Lilacs databases, with publishing dates ranging from January 1992 to March 2014. The articles included consisted of English-speaking experimental studies in which SEPFM were compared with placebo treatment (usual or untreated). The sample had a diagnosis of SUI and their age ranged between 18 and 65 years. The assessment of methodological quality was performed based on the PEDro scale. Results: Seven high methodological quality articles were included in this review. The sample consisted of 331 women, mean age 44.4±5.51 years, average duration of urinary loss of 64±5.66 months and severity of SUI ranging from mild to severe. SEPFM programs included different training parameters concerning the PFM. Some studies have applied abdominal training and adjuvant techniques. Urine leakage cure rates varied from 28.6 to 80%, while the strength increase of PFM varied from 15.6 to 161.7%. Conclusion: The most effective training protocol consists of SEPFM by digital palpation combined with biofeedback monitoring and vaginal cones, including 12 week training parameters, and ten repetitions per series in different positions compared with SEPFM alone or a lack of treatment.

Resumo Introdução: Os exercícios de fortalecimento dos músculos do pavimento pélvico (EFMPP) são considerados a primeira intervenção no tratamento da incontinência urinária de esforço (IUE); porém, não existe evidência sobre os parâmetros de treino. Objetivo: Identificar o protocolo e/ou os parâmetros de treino mais eficazes no tratamento da IUE feminina. Método: A pesquisa bibliográfica foi realizada entre janeiro de 1992 e março de 2014 nas bases de dados PubMed, Cochrane Library, PEDro, Web of Science e Lilacs. Os artigos incluídos eram de língua inglesa, estudos experimentais, comparando EFMPP com tratamento placebo, usual ou sem tratamento, com idade compreendida entre 18 e 65 anos e diagnóstico de IUE. A avaliação da qualidade metodológica foi realizada por meio da escala PEDro. Resultados: Sete artigos de elevada qualidade metodológica foram incluídos na presente revisão. A amostra foi constituída por 331 mulheres, com idade média de 44,4±5,51 anos, duração média das perdas urinárias de 64±5,66 meses e gravidade da IUE variando entre ligeira e grave. Os programas de EFMPP eram distintos relativamente aos parâmetros de treino dos MPP. Alguns estudos incluíram treino abdominal e técnicas adjuvantes. A taxa de cura da quantidade de perda urinária variou entre 28,6 e 80%, enquanto o aumento da força dos MPP variou de 15,6 a 161,7%. Conclusão: O protocolo de treino mais eficaz consiste nos EFMPP por palpação digital e supervisão combinados com biofeedback e cones vaginais, incluindo os parâmetros de treino de 12 semanas de duração, dez repetições por série e em distintas posições comparados com os EFMPP isolados ou sem tratamento.

Long-term Outcome of the Retrourethral Transobturator Male Sling After Transurethral Resection of the Prostate / 대한배뇨장애요실금학회지

PURPOSE: To evaluate long-term outcomes of AdVance and AdVanceXP male slings in patients with persistent stress urinary incontinence (SUI) after transurethral resection of the prostate (TURP). METHODS: A total of 18 consecutive patients received AdVance (n=14) or AdVanceXP (n=4) male sling implantation between 2007 and 2013. Continence was determined by pad use, 24-hour pad testing and validated questionnaires (International Consultation on Incontinence Questionnaire Short Form, ICIQ-SF). Quality of life was evaluated by International Quality of Life (IQoL) score. Patient satisfaction was measured with patient’s global impression of improvement score. Cure was defined as 0–5 g in the 24-hour pad test. Statistical analysis included Fisher exact and Wilcoxon test (P<0.05). RESULTS: Follow-up was available for 15 patients who underwent further analysis. After a median follow-up of 70 months (range, 18–83 months), mean daily pad usage was 1.8±2.1 pads (P=0.015 vs. baseline level). Mean IQoL score was 66.4±31.6 (P=0.050 vs. baseline level), and mean ICIQ-SF score was 9.5±6.6 (P=0.077 vs. baseline level). Based on 24-hour pad testing, mean daily urine loss was 31.2±64.5 g (median, 0 g; range, 0–209 g). Cure rate was 46.7%, and cure-and-improved rate was 60.0%. Assessing predictive features for success, better results were found in patients who needed up to 4 pads preoperatively (P=0.041) as well as for patients ≤71 years at the time of implantation (P=0.041). CONCLUSIONS: The findings indicate that AdVance and AdVanceXP implantation can be performed effectively and safely in men suffering from SUI after TURP. However, long-term success rates seem to be lower compared to SUI after radical prostatectomy and patients should be counseled accordingly.

Effect of Preoperative Flow Rate on Postoperative Retention and Voiding Difficulty After Transobturator Tape Operation

PURPOSE: Controversy exists over the preoperative risk factors for postoperative urinary retention after the midurethral sling procedure for stress urinary incontinence (SUI). We intended to analyze the effect of preoperative flow rate on postoperative urinary retention after the transobturator tape (TOT) operation. MATERIALS AND METHODS: A total of 322 patients who underwent TOT from June 2006 to May 2012 were included in this retrospective study. All patients were preoperatively investigated for urinary symptoms and underwent preoperative urodynamic studies including urine flow rate. Postoperative urinary retention, voiding difficulty, and uroflowmetry were checked. Urinary retention was defined as the need for additional catheterization longer than 1 day. Patients were divided by preoperative peak flow rate (Qmax) of 15 mL/s (low Qmax group and normal Qmax group). RESULTS: There were 3 cases of postoperative urinary retention (0.9%) and 52 cases of voiding difficulty (16.1%). The low Qmax group included 40 patients (12.4%) and the normal Qmax group included 282 patients (87.5%). Between the two groups, there were no significant differences in age, previous pelvic surgery history, or past medical history. The low Qmax group had higher scores for voided volume and detrusor pressure at Qmax. However, there was no significant difference in postoperative voiding difficulty between the two groups. Furthermore, three patients who experienced postoperative retention showed high flow rates preoperatively. CONCLUSIONS: Our results suggest that voiding difficulty in the group with low preoperative flow was tolerable and the treatment success rate was comparable to that in patients in the normal flow group. According to our analysis, patients with a low flow rate preoperatively can be safely treated with TOT for SUI.

Cincha transobturatriz con anestesia local para incontinencia urinaria de esfuerzo / Tansobturator tape under local anesthesia for urinary stress incontinence

Evaluar la técnica de cura de incontinencia urinaria de esfuerzo con cincha transobturatriz bajo anestesia local. Estudio descriptivo y prospectivo en 22 pacientes con incontinencia urinaria de esfuerzo de la consulta de piso pélvico del Hospital Universitario de Caracas entre abril y noviembre de 2010, a las que se les colocó cincha transobturatriz con anestesia local y sedación consciente complementaria en la mayoría de los casos. El tiempo quirúrgico promedio fue 9,57 min. Dos pacientes toleraron el procedimiento quirúrgico con anestesia local exclusiva, mientras que las otras 20 (90,9 por ciento) requirieron sedación endovenosa, similar a lo descrito en la literatura. El dolor intraoperatorio en promedio fue de 3,18 puntos en la escala visual análoga. El 100 por ciento de las pacientes estuvo satisfecha con el procedimiento anestésico y el 95,5 por ciento lo recomienda. La anestesia local con sedación consciente constituye una técnica tolerable, segura, y rápida para la cura de incontinencia urinaria de esfuerzo con cincha transobturatriz

To evaluate the transobturator tape procedure for urinary stress incontinence under local anesthesia. Prospective and descriptive study of 22 patients with urinary stress incontinence from the Pelvic Floor Unit of Universitary Hospital of Caracas, between April and November 2010, in whom the transobturator tape procedure was performed under local anesthesia and sedation. Mean surgical time was 9.57 min. Two patients tolerated the surgical procedure with local anesthesia without sedation, while the other 20 (90.9 percent) required intravenous sedation, as described in most publications. Mean intraoperative pain was 3.18 points in the Visual Analogue Scale. One hundred percent of the patients were satisfied with the anesthetic technique, and 95.5 percent would recommend it. Local anesthesia with sedation is a well-tolerated, safe, and fast technique for the surgical treatment of urinary stress incontinence with transobturator tape

Complications Following Outside-in and Inside-out Transobturator-Tape Procedures with Concomitant Gynecologic Operations / 전남의대학술지

This study was undertaken to compare the complications of outside-in transobturator tape procedures (TOT) and inside-out transobturator tape procedures (TVT-O) with concomitant gynecologic surgery for the treatment of female stress urinary incontinence (SUI). A retrospective review of 206 consecutive patients who underwent either TOT or TVT-O with concomitant gynecologic operations between March 2008 and February 2011 was conducted. The incidence of perioperative complications was compared. For statistical analysis, chi-squared tests were used. There were no reports of intraoperative complications such as vaginal injury or bladder perforation. Postoperative complications were noted in 23 procedures (11.2%). These included 6 cases of urinary retention (2.9%), 2 cases of vulva hematoma (1.0%), 7 cases of urinary tract infection (3.4%), 4 cases of de novo urgency (2.9%), and 4 cases of vaginal erosion (2.9%). There were no significant differences in complication rates between the two groups. Our results suggest that inside-out and outside-in procedures are simple and safe techniques that may have a low rate of complications when used with a concomitant gynecologic operation.

Efficacy and Safety of the TVT-SECUR(R) and Impact on Quality of Life in Women with Stress Urinary Incontinence: A 2-Year Follow-Up

PURPOSE: As recently reported, the short-term results of the tension-free vaginal tape SECUR(R) (TVT-S) procedure seem to be similar to those of the conventional transobturator tape (TOT) procedure. However, results of efficacy and satisfaction with TVT-S are insufficient in patients with more than 1 year of follow-up. Therefore, we evaluated the results of the TVT-S procedure in women with stress urinary incontinence (SUI) during 2 years. MATERIALS AND METHODS: We evaluated 51 patients with clinical and urodynamic diagnoses of SUI who underwent the TVT-S procedure from March 2008 to February 2009. Preoperative evaluation included a history, cough stress test with full bladder, urodynamic study, and incontinence quality of life (I-QoL) questionnaire. Following the postoperative period, urinary incontinence status was examined through a physical examination and the I-QoL questionnaire was completed in an outpatient setting or by telephone. RESULTS: Data from 2 years of follow-up were available for 46 of 51 patients. The cure rate was 80.4% at 1 month after TVT-S and 76.0% at 2 years after TVT-S. The cure or improvement rate was 93.5% at 1 month after TVT-S and 86.8% at 2 years after TVT-S. The mean total I-QoL score increased by 42 points at 1 month after TVT-S (p<0.026) and by 32 points at 2 years after TVT-S (p<0.013). Most patients reported significant improvements in quality of life. At the 2-year follow-up, there were no significant complications related to TVT-S. CONCLUSIONS: The results of this study suggest that TVT-S is an efficient and safe procedure for the improvement of both the quality of life of the patients and the SUI itself.

Tape Shortening for Recurrent Stress Urinary Incontinence After Transobturator Tape Sling: 3-Year Follow-up Results / 대한배뇨장애요실금학회지

PURPOSE: Recently, as the number of transobturator tape (TOT) procedures has increased, recurrence after this procedure has been frequently reported. However, there are no standard guidelines for treatment. We describe our experience with shortening the previously implanted tape in patients with recurrent stress urinary incontinence after the TOT procedure. MATERIALS AND METHODS: We enrolled 10 women who underwent shortening of the previously implanted tape and were followed up for 3 years. Shortening of the previously implanted tape was done by a figure-eight suture with 1-0 Prolene. One year after TOT shortening, we investigated continence status, patient satisfaction by means of a questionnaire, maximal flow rate (Qmax), and postvoid residual urine volume. Three years after TOT shortening, we evaluated continence status and patient satisfaction. RESULTS: The mean period of TOT shortening was 4.2 months (range, 1-12 months) after the TOT procedure. One year after TOT shortening, 7 patients showed complete dryness, 2 patients showed improvement, and 1 patient reported failure. Eight patients were very satisfied or satisfied with the 1-year result after TOT shortening. The mean preoperative and postoperative Qmax were 23.8 and 26.7ml/s, respectively, and there was no significant difference. Three years after TOT shortening, 6 patients showed complete dryness, 2 patients showed improvement, and 2 patients reported failure. Among them,1 had failed from 1 year after TOT shortening and the other had shown 1 year of complete dryness. Eight patients were very satisfied or satisfied and 2 patients were dissatisfied with the 3-year result after TOT shortening. CONCLUSION: Most of the patients who underwent TOT shortening reported satisfaction as well as improvement of incontinence after a 3-year follow up. Therefore, we suggest that TOT shortening may be recommended primarily in patients with recurrent stress urinary incontinence after the TOT sling procedure.

Acute and Serious Myositis with Abscess in Thigh Muscle after Transobturator Tape Implantation / 대한배뇨장애요실금학회지

The complications of transobturator tape (TOT) were known as lower urinary tract injury, postoperative urinary retention, urge incontinence, vaginal erosion, and etc. A 63-year-old woman presented with new onset of severe pain, heating, and swelling of the left thigh and perineum. She had undergone TOT implantation for stress urinary incontinence (SUI) 4 days previously in an outside clinic. Painful left thigh swelling and skin erythema were noted on the physical examination. A computed tomography (CT) scan showed multiple, large left medial thigh and obturator abscesses. Removal of the implanted tape and abscess drainage were performed immediately and two additional operations were needed for proper abscess drainage. We believe this case to be one of the most serious complications to occur since the introduction of the TOT procedure. Here we report this case and discuss its initial management along with a review of the literature.

Comparison of Efficacy and Satisfaction between the TVT-SECUR(R) and MONARC(R) Procedures for the Treatment of Female Stress Urinary Incontinence

PURPOSE: The tension-free vaginal tape SECUR(R) (TVT-S) is a new, minimally invasive sling procedure for treating female stress urinary incontinence (SUI). However, results of comparisons of the TVT-S with the transobturator tape (TOT) sling are lacking. Therefore, we investigated outcome and satisfaction of the TVT-S procedure compared with the TOT procedure. MATERIALS AND METHODS: We included 64 patients with SUI who underwent the TVT-S (n=31) or TOT (MONARC(R), n=33) procedure and were followed up for more than 1 year. The preoperative evaluation included history taking, pelvic examination, consecutive 3-day voiding diary, and urodynamic study including Valsalva leak point pressure. Postoperatively, continence status and subjective patient satisfaction were evaluated. Cure was defined as the absence of any episodes of involuntary urine leakage during stressful activities and a stress cough test. RESULTS: The TVT-S group (71.0%) showed a slightly lower cure rate than did the MONARC group (84.8%); however, there was no significant difference between the 2 groups (p=0.179). Nine of the patients who underwent the TVT-S showed incontinence postoperatively. Among them, the H approach was used in 7 patients and the U approach was done in 2 patients. Following TVT-S and MONARC, the patients' reported satisfaction was 80.6% and 78.8%, respectively. Patient satisfaction did not differ significantly between the two groups (p=0.854). CONCLUSIONS: Our results showed that the TVT-S and MONARC procedures may be comparable in terms of cure rate and patient satisfaction after more than 1 year of follow-up.

The Influence of Preoperative Bladder Outlet Obstruction on Continence and Satisfaction in Patients with Stress Urinary Incontinence after Midurethral Sling / 대한배뇨장애요실금학회지

PURPOSE: We studied the influence of preoperative bladder outlet obstruction (BOO) on postoperative continence rates and patient satisfaction after the midurethral sling procedure. METHODS: A total of 159 women who underwent the midurethral sling procedure were evaluated. Using the Blaivas-Groutz nomogram, we assigned the patients were assigned to Group I (n=37, no obstruction), Group II (n=89, mild obstruction), or Group III (n=33, moderate to severe obstruction). Continence rates, patient satisfaction, urinary sensation scale and uroflowmetry were evaluated postoperatively. RESULTS: There were no significant differences in continence rates, satisfaction, or postoperative maximal flow rate between the 3 groups. Postoperative urgency was improved after surgery in Groups I and II (P<0.05) but not in Group III. CONCLUSIONS: BOO does not seem to be a risk factor for failure after the midurethral sling procedure. However, BOO may be considered as a potential factor for persistent storage symptoms after the midurethral sling.

Cabestrillo subtrigonal con aponeurosis abdominal en el tratamiento de incontinencia urinaria de esfuerzo compleja / Subtrigonal sling with abdominal fascia for treatment of complex stress urinary incontinence

Objetivo: Describir la técnica de cabestrillo subtrigonal con fascia abdominal y demostrar su utilidad en la resolución de la incontinencia urinaria de esfuerzo compleja. Material y métodos: Estudio de cohorte longitudinal y observacional en mujeres adultas que acudieron al Servicio de Urodinamia, Hospital de Especialidades, Centro Médico Nacional Siglo XXI, para tratamiento de incontinencia urinaria de esfuerzo recidivante o con factores de riesgo para recidiva, asociada o no a incontinencia urinaria de urgencia. Resultados: Entre 1995 y 2006 incluimos 40 pacientes; el seguimiento fue de 41.95 meses (rango 9 a 106) y el promedio de edad de 55 años. En 35 pacientes (87.5 %) fue resuelta la incontinencia urinaria de esfuerzo, dos pacientes mejoraron (5 %) y tres persistieron (7.5 %) con la incontinencia. De las 40 pacientes, 18 presentaban incontinencia urinaria de urgencia y solo en siete de éstas (39 %) se resolvió después de la cirugía. La incontinencia urinaria de urgencia de novo se presentó en 12 (30 %). Una tuvo hernia crural, dos hernia posincisional y dos requirieron transfusión sanguínea. Ninguna evidenció problemas de vaciamiento urinario posterior a la cirugía. Conclusiones: Los resultados con la técnica descrita son eficaces y duraderos en pacientes con incontinencia urinaria de esfuerzo recidivante o factores de riesgo para recidiva. No se observó disfunción de vaciamiento vesical, sin embargo, hubo hernias abdominales. El abordaje de mínima invasión para colocar las cintas sintéticas en posición subtrigonal podría mantener la eficacia con mínima morbilidad.

BACKGROUND: The aim of this study was to describe the technique of subtrigonal sling with abdominal fascia and demonstrate its usefulness in resolving complex stress urinary incontinence (SUI). METHODS: We performed a cohort, longitudinal, observational study in adult females who attended the Urodynamics Department of the Hospital de Especialidades, Centro Medico Nacional Siglo XXI, Mexico City, with recurrent SUI or with risk factors for recurrence, whether or not associated with urge urinary incontinence (UUI). RESULTS: Between 1995 and 2006, 40 patients were included. Mean follow-up was 41.95 months (9-106), and the average patient age was 55 years. In 35 patients (87.5%) SUI was resolved, in two patients (5%) it improved, and in three patients (7.5%) it persisted. Of the 40 study patients, 18 had UUI and in only 7/18 patients (39%) was it resolved postoperatively. UUI de novo was noted in 12/40 patients (30%). One patient presented crural hernia, two patients presented postincisional hernia and two patients required blood transfusion. No patient presented acute urinary retention or urinary voiding problems postoperatively. CONCLUSIONS: Results obtained by this surgical technique are effective and long-lasting in patients with complex SUI. We did not observe bladder emptying dysfunction but there were formations of abdominal wall hernias. The minimally invasive approach consisting of the subtrigonal placement of synthetic tapes may maintain efficacy with minimal morbidity.

Parâmetros da urofluxometria e do estudo fluxo/pressão em pacientes uroginecológicas / Uroflowmetry and flow pressure study parameters in urogynecology patients

OBJETIVO: Avaliar as taxas de fluxo no estudo urodinâmico (EUD) em pacientes com disfunção do trato urinário inferior e registrar os efeitos do diagnóstico final do EUD e da idade das pacientes sobre estas variáveis. MÉTODOS: Estudo retrospectivo que incluiu 205 mulheres. As pacientes foram divididas em três grupos: menos de 45 anos; entre 45 e 60 anos e mais que 60 anos. Estudamos os comportamentos dos fluxos máximo, médio e da pressão de abertura do detrusor (Padet) com o evoluir da idade. De forma semelhante, realizamos comparações das variáveis fluxos máximo e médio, Padet e vesical no fluxo máximo, consoante o diagnóstico final do EUD. RESULTADOS: Há forte declínio dos fluxos máximo, médio e da Padet com o evoluir da idade, sendo que a queda dos fluxos máximo e médio é significante quando comparamos as mulheres com mais de 65 anos (21,8 ml/s e 9,2 ml/s, respectivamente) com aquelas entre 45 e 60 anos (29 ml/s e 12,6 ml/s, respectivamente) e as demais (27,9 ml/s e 11,7 ml/s, respectivamente). Observamos redução significativa da Padet no grupo com mais de 60 anos (13,4 cmH2O) quando comparadas àquele com menos de 45 anos (21,2 cmH2O). A Padet teve redução significativa nas pacientes com incontinência urinária de esforço (IUE) associada a defeito esfincteriano (13,8 cmH2O) diagnosticados no EUD quando comparadas aquelas assintomáticas (20,7 cmH2O). CONCLUSÃO: Há diminuição das taxas de fluxo com o aumento da idade. Mulheres com IUE têm micção com menor Padet.

OBJECTIVE: The purpose was to evaluate urine flow rates in an urodynamic study (US) of patients with symptoms of lower urinary tract dysfunction and to record effects of final urodynamic diagnosis and age on these variables. METHODS: Retrospective analysis of 205 women who had undergone urogynecological investigation. Patients were divided into three age groups: A (< 45 years); B (45 - 60 years) and C (> 60 years). Comportment of urine flow rates and opening detrusor pressure with increasing age were studied and resulting charts recorded. Comparison of maximum and average urine flow rates, opening detrusor pressure and detrusor pressure at the maximal flow according to final urodynamic diagnostic were also made. RESULTS: There was a decline of urine flow rates with increase of age, which was more significant between groups A X C and B X C. There was also a decline in opening detrusor pressure with aging, which was significant between groups A X C. When analyzing opening detrusor pressure according to final urodynamic diagnosis, a significant decline of this variable was observed in patients with urinary stress incontinence and intrinsic sphincter deficiency in relation to those who were asymptomatic. CONCLUSION: Urine flow rates decreased with age. Women with urinary stress incontinence and intrinsic sphincter deficiency void at a lower detrusor pressure.

Cincha de prolene suburetral por vía trans obturatriz en pacientes obesas: experiencia del Hospital del Salvador / Transobturator prolene sling in obese patients: single center experience

La incontinencia urinaria de esfuerzo (IOE) ha sido asociada a obesidad en numerosos estudios. A pesar de que la baja de peso puede mejorar la IOE en estas pacientes, la cirugía como tratamiento definitivo permite obtener mejores resultados. La cincha suburetral por vía trans obturatriz (TOT), ha tenido excelentes resultados como cirugía inicial para el manejo de IOE, pero hay escasos reportes acerca de su uso en pacientes obesas. Objetivo: Evaluar el efecto de la obesidad en el éxito de TOT para el tratamiento de la IOE. Materiales y Métodos: Estudio de cohorte retrospectivo que identificó a 25 pares de pacientes sometidos a TOT en la Unidad de Urología del Hospital del Salvador entre enero de 2002 y mayo de 2005. Las pacientes obesas (definidas como un IMC > o = a 30 Kg/m2) fueron comparadas con pacientes no obesas (IMC < a 30 Kg/m2). Se comparó según edad (dentro de 5 años) y cirugía previa de incontinencia. El seguimiento fue realizado en forma objetiva con el test de estrés inducido por tos y subjetivamente a través de una encuesta telefónica que evaluaba mejoría. Cura fue definida como la ausencia de IOE después de la cirugía. El análisis estadístico fue realizado a través de regresión logística para cada control. Resultados: El seguimiento promedio varió entre 6 y 24 meses. Existieron 5 fallas, 3 en pacientesobesas y 2 en no obesas, resultando en una tasa de cura de 88,6 por ciento y 91,4 por ciento respectivamente. Esta diferencia no logró diferencia estadística (p>0,05). Existió una perforación de pared vaginal lateral en el grupo no obeso. Conclusión: Estos datos no demuestran una diferencia respecto al éxito de TOT en pacientes obesas v/s no obesas. Dadas las escasas complicaciones encontradas, este procedimiento podría ser el tratamiento quirúrgico ideal para el manejo de la IOE en pacientes obesas.

Stress urinary incontinence (SUI) has classically been associated with numerous studies. Reducing body mass index (BMI) may benefit some patients; however complete remission of SUI is often obtained by surgical means. Transobturator sling (TOT) has become a standard practice with clear benefits; nevertheless series in obese patients are scarce. We evaluate the success of TOT in obese patients. Materials and Methods: A retrospective cohort study was performed in 25 patients that under went TOT between January 2002 and May 2005 at our institution. Obese patients (BMI > or = 30 Kg/m2) were compared with non obese patients. Patients were monitored with office control and by telephone. Cure was established in the absence of SUI. Logistic regression was performed for each case. Results: Follow up was between 6 and 24 months. TOT failed in 5 patients (3 obese). Cure was obtained in 88.6 percent and 91.4 percent for obese and non obese patients respectively; however this difference was not statistically significant (p>0.05). Vaginal wall perforation occurred in one case of the non obese group. Conclusion: There is no difference in TOT success rate between obese and non obese patients. Due to its low complication rate, we relieve TOT to be the ideal treatment of obese patients with SUI.

Changes in Voiding Patterns after Transobturator Tape Operation in Female Patients with Stress Urinary Incontinence / 대한비뇨기과학회지

PURPOSE: A lot of patients with stress urinary incontinence(SUI) have lower urinary tract symptoms. So we evaluated the changes of voiding pattern following transobturator tape(TOT) operation, and investigated the factors for predicting persistent urinary frequency after operation. MATERIALS AND METHODS: The items of preoperative evaluations consisted of history taking, physical examination, cystometrography, 3 day frequency-volume chart and symptoms questionnaire. Patients with anticholinergics or any neurologic diseases that affect the voiding pattern were excluded. Between January to November 2006, 46 patients with TOT operation were enrolled, and were reevaluated with physical examination, 3 day frequency-volume chart and symptom questionnaires, postoperatively. RESULTS: The patients who voided 8 or more times per day had shorter symptom duration and higher body mass index(BMI) than those who voided under 8 times per day(each p<0.05). In 30 patients who void 8 or moretimes per day preoperatively, 17(56.7%) patients became void under 8 times, postoperatively. In each patient who had urgency or urge incontinence symptoms preoperatively, respective 72.7 and 82.8% resolved their symptoms, postoperatively. No one complained de novo urgency or urge incontinence, postoperatively. In a multivariate analysis, the patient with a history of previous pelvic surgery or moderate to severe urge incontinence was tightly associated with an increased likelihood of persistent urinary frequency after TOT operation (odd ratio[OR] 24.8, 95% confidence interval[CI] 2.044-301.284, p=0.012 and OR 31.9, 95% CI 1.662- 613.619, p=0.022, respectively). CONCLUSIONS: The TOT operation can improve the symptoms of urinary frequency, urgency and urge incontinence in patients with SUI. However, the patients who had previous pelvic surgeriesor moderate to severe urge incontinence should be fully advised for the risk of sustaining frequency, postoperatively

Comparison of the Short Term Results of Monarc and TVT-O Transobturator-tape Procedures for the Treatment of Stress Urinary Incontinence

PUROPOSE: Transobturator sling is a new minimally invasive treatment for female stress urinary incontinence. We compared the efficacy and safety of the two procedures, Monarc and TVT-O. MATERIAL AND METHODS: We included 110 patients with stress urinary incontinence who underwent the Monarc (n=52) or TVT-O (n=58) procedure and followed up at least for 1 year. Preoperative evaluations, the indices of voiding and postoperative complication were investigated. They were analyzed by Student's t-test, Paired t-test and chi-square test. RESULTS: There were no significant difference in the preoperative patients' characteristics, postoperative complication and success rate between the two groups. The preoperative and postoperative storage symptoms between two groups had no significant difference but the patients of both groups had significant improvement in storage symptoms such as frequency and urgency after surgery. CONCLUSIONS: The Monarc and TVT-O is equally effective and safe procedures as a treatment method of female stress urinary incontinence.

Therapeutic effects of tension-free vaginal tape and tension-free vaginal tape obturator in women with stress urinary incontinence:meta analysis / 中华泌尿外科杂志

Objective To assess the effectiveness of tension-free vaginal tape obturator tape(TVT-O)as treatment of SUI by means of a systematic review and meta analysis.Methods Using the search terms"TVT,TVT-O,SUI,RCT,TOT",the literature in Chinese and English from January 2001 tO March 2007 on the difference of TVT and TVT-O was searched from MEDLINE,PUBMED,EMBASE,Google Scholar,CNKI,WAN FANG DATA,and criteria randomized controlled trials(RCTs)were studied by Meta-analysis in RevMan 4.2.At the same time,Ors of randomized model and fixed model were calculated tO evaluate the sensitivity.Results There were six RCTs that compared TVT-O with TVT.When compared by Subjective cure,TVT-O at 1-17 months were no better than TVT(OR 0.67;95% CI 0.40,1.13).Adverse events such as bladder injuries (OR 0.15;95% CI 0.03,0.66)was less common,where as groin/thigh pain(OR 8.61;95% CI3.03,24.52)was more common;but there were rio significant difference in de novo urgency(OR=1.16;95% CI 0.54,2.47),urinary retention(OR=0.54;95% CI 0.24,1.20)or urinary tract infection(OR=1.07;95% CI 0.61,1.87)between the tWO groups.Conclusions There is no significant difference between TVT and TVT-O.TVT-O group had no bladder injuries complications,but groin/thigh pain was more common.

The Quality of Life after Tension-Free Vaginal Tape and Transobturator Vaginal Tape Inside-Out for the Surgical Treatment of Female Stress Urinary Incontinence

PURPOSE: The change of quality of life following a tension-free vaginal tape (TVT) and transobturator vaginal tape (TVT-O) procedure was investigated in patients with stress urinary incontinence. MATERIALS AND METHODS: We included 86 women with stress urinary incontinence who underwent the TVT or TVT-O procedure and followed up for at least 1 year. Preoperatively, the patients were evaluated with history taking, physical examination, urodynamics to determine abdominal leak point pressure (ALPP) and pre- and postoperative quality of life was evaluated by incontinence quality of life questionnaire (I-QoL). The success after operation was defined as the absence of any subjective complaint of leakage. RESULTS: The rate of cure of TVT and TVT-O procedure were 84%, 92% and the rate of improvement of them were 16%, 8%, respectively. Preoperative patient characteristics including uroflowmetric parameters and ALPP were comparable in the two groups. The I-QoL parameters one year after surgery were statistically significant increase in I-QoL scores in each groups. There were no serious or long-term complications related to both procedures. CONCLUSIONS: These data suggest that the TVT and TVT-O procedure are effective for treating female stress incontinence and also in the aspect of improving quality.

The Effects of Pelvic Floor Muscle Exercise on Urinary Symptoms and Quality of Life in Women with Stress Urinary Incontinence

PURPOSE: The purpose of this study was to identify the effects of pelvic floor muscle exercise on reducing the symptoms of stress urinary incontinence and improving attitude toward exercise and quality of life. METHOD: The research adopted was a nonequivalent control group pretest posttest design. The subjects were 55 persons who were surveyed using a structured questionnaire, and 23 persons in the experimental group among the total sample were measured for the peak pressure and the duration of PMC and trained correct pelvic floor muscle contraction using peritron in the first week. Then, pelvic floor muscle exercise was implemented for 6 weeks. The data was analyzed by chi2-test and t-test with the SPSS 10.0 program. RESULTS: 1) The degree of stress urinary incontinence, frequency of urination, nocturia, urgency, noctural incontinence, the frequency and quantity of incontinence, outer clothing change and incomplete emptying decreased significantly more in the experimental group than in the control group. 2) Attitude toward pelvic floor muscle exercise and the quality of life were improved significantly more in the experimental group than in the control group. 3) The peak pressure and duration of PMC increased significantly more in the posttest. CONCLUSION: Based on the results above, it is judged that pelvic floor muscle exercise is an effective nursing intervention in order to care for stress urinary incontinence.

Comparative Study on the Modified Transobturator Tape(TOT) and Conventional Mid-urethral Sling by TOT

PURPOSE: We have developed and applied novel modification of the sling tape covering mid-urethra more widely. This is to evaluation clinical result of this novel sling tape. MATERIALS AND METHODS: 145 women with SUI were enrolled in a prospective randomized study. We have used a Prolene modified transobturator suburethral tape(M-TOT), in which the width of middle 20 mm portion was designed to cover wide portion of the urethra(17 mm) compared to the width of 11 mm of the conventional tape. The operative results were compared with those of conventional TOT. RESULTS: 145 patients were included in the study(52 with M-TOT and 93 with conventional TOT). Success rate and satisfaction rate was not different between two groups. In patients with intrinsic sphincter deficiency (ISD), success rate and satisfaction rate were significantly higher in the M-TOT group. Post-operative parameters including peak flow rate were not different between groups. De novo urgency was developed in 3 patients treated with M-TOT but was significantly fewer than those with conventional TOT. CONCLUSION: Modified TOT designed for supporting bladder neck as well as mid-urethra showed comparable success rate with conventional TOT with no differences in postoperative voiding function. Furthermore, M-TOT seems to be more efficient than conventional TOT in the management of SUI associated with ISD.
