Progression in the treatment of female stress urinary incontinence with underactive bladder / 现代泌尿外科杂志

Stress urinary incontinence (SUI) and underactive bladder (UAB) are common types of lower urinary tract dysfunction in women.As the treatment mechanisms of the two conditions are contradictory, the treatment of SUI patients complicated with UAB remains a difficult clinical problem.In order to improve the treatment rate of such patients and promote research, this paper reviews the latest domestic and overseas diagnostic criteria of UAB, summarizes the treatment experience of conventional midurethral sling (tension-free vaginal tape or outside-in transobturator tape) and adjustable sling procedures (transobturator adjustable tape or Remeex system) combined with medication or intermittent catheterization, and the application prospects of cutting-edge technologies such as stem cell injection, cytokine therapy and gene therapy, so as to provide reference for clinicians and researchers.

Efficacy of modified TOT surgery on patients with failed previous anti-incontinence procedures / 现代泌尿外科杂志

【Objective】 To analyze the causes of the failure of previous operations in female patients with stress urinary incontinence (SUI), and to evaluate the efficacy and safety of modified transobturator outside-in tape (TOT). 【Methods】 A total of 42 female SUI patients who had failed in previous anti-incontinence surgery during Aug.2016 and Jul.2022 were enrolled. The causes of failure were analyzed. All patients were treated with modified TOT, and the operation time, estimated blood loss, duration of catheterization, symptom improvement and complications were observed. The outcomes were evaluated with the International Consultation on Incontinence Questionnaire Short Form (ICI-Q-SF), pad test and urodynamic study. 【Results】 All operations were technically successful. The average operation time was (32.4±18.6) min, and estimated blood loss was (54.2±34.5) mL. There were no obvious complications. After operation, the ICI-Q-SF score significantly decreased (P0.05). The overall effective rate was 88.1%. 【Conclusion】 Modified TOT can be used for the treatment of patients with failed anti-SUI surgery, which is simple and easy to perform, with a low complication rate and satisfactory postoperative results.

Clinical observation of adjusting middle urethral sling tension through anatomic position during RMUS / 中华泌尿外科杂志

Objective:To investigate the safety and effectiveness of tension adjustment technique using anatomical landmarks during retropubic midurethral synthetic sling.Methods:The data of 36 consecutive female patients with urinary incontinence, who had underwent retropubic midurethral synthetic sling procedure from January to August 2019 were analyzed retrospectively. The mean age was (60.83±7.93) years old and the body mass index was (24.43±2.44) kg/m 2. Among the recruited subjects, 36 had positive stress test and Marshall-Marchetti test. 20 (55.6%) were pure stress urinary incontinence, and 16 (44.4%) were mixed urinary incontinence. The severity of incontinence was classified into mild (5 cases, 13.9%), moderate (14 cases, 38.9%), severe (13 cases, 36.1%) and very severe (4 cases, 11.1%) using one-hour pad tests. Urodynamics were performed in 17 cases, with 5 (29.4%) presented detrusor overactivity, 3 (17.7%) possessed intrinsic sphincter deficiency. For each case, the tension of the sling was adjusted based on the anatomical landmarks, i. e. using an angled clamp attached closely to the pubic symphysis ventrally and the tip parallel to the edge of hymen dorsally. All patients were catheter-free right after the procedure. The subjective and objective effectiveness, and safety (the rate of urinary retension after surgery and postvoid residual volume 3 months later) were evaluated.The subjective cure rate was was defined as complete leakage free or very mild leakage during excessive bladder filling and fierce cough. The subjective effectiveness was defined as over 50% improvement of the leakage symptom. The objective cure rate was defined as a negative stress test. Results:For all 36 patients, the median hospital stays was 8 (5-95)h. No bladder perforation or transfusion cases. All patients were catheter-free right after the procedure, with no incidence of urinary retention. 27 patients completed a 3-month follow-up, with 22 had post-void residual data, 23 had subjective effectiveness data and 23 had objective effectiveness data. The median post-void residual was 7.5 (5-64) ml, subjective cure rate was 91.3% (21/23), and objective cure rate was 95.7% (22/23). 8.7% (2/23) reported difficult urination alleviated without the necessity of clinical interference. No urethra erosion or vagina extrusion was found. At 2-year follow-up, 34 patients completed assessment by phone. The subjective cure rate was 91.2% (31/34), with only 2.9% (1/34) reported difficult urination. Besides, at 3-month follow-up, there was no difference regarding the subjective cure rate [100.0%(12/12) vs. 81.8%(9/11)]or objective cure rate [91.7%(11/12) vs. 100.0%(11/11)] between patients with stress and mixed incontinence. No difference was noted among patients with mild, moderate, severe and very severe leakage[75.0% (3/4) vs. 100.0%(6/6) vs. 90.0%(9/10) vs. 100.0%(3/3)]. Of the 12 cases with urodynamic records, the presence of detrusor overactivity [66.7%(2/3) vs. 88.9%(8/9)] or intrinsic sphincter deficiency [0(0/1) vs. 90.9%(10/11)] did not significantly affected the cure rate of the procedure. At 2-year follow-up, there was no difference regarding the subjective cure rate between patients with stress and mixed incontinence [94.7%(18/19) vs. 86.7%(13/15)]. No difference was also noted among patients with mild, moderate, severe and very severe leakage[80.0%(4/5) vs. 100.0%(13/13) vs. 83.3%(10/12) vs. 100.0%(4/4)]. Of the 16 cases with urodynamic records, the presence of detrusor overactivity [60.0%(3/5) vs. 90.9%(10/11)]or intrinsic sphincter deficiency [66.7%(2/3) vs. 84.6%(11/13)]did not significantly affected the cure rate of the procedure.Conclusions:Tension adjustment using anatomic landmarks during sling procedure is safe and feasible for urinary incontinence, with minimum complications and residual volume, and high subjective/objective cure rate.

Surgical treatment for stress urinary incontinence in women: A systematic review and meta-analysis / Tratamento cirúrgico da incontinência urinária de esforço em mulheres: revisão sistemática e metanálise

Abstract Objective To compare surgical treatments for stress urinary incontinence in terms of efficiency and complications. Data Sources We searched the MEDLINE and COCHRANE databases using the terms stress urinary incontinence, surgical treatment for stress urinary incontinence and sling. Selection of Studies Forty-eight studies were selected, which amounted to a total of 6,881 patients with scores equal to or higher than 3 in the Jadad scale. Data Collection Each study was read by one of the authors, added to a standardized table and checked by a second author. We extracted data on intervention details, follow-up time, the results of treatment and adverse events. Data Synthesis Comparing retropubic versus transobturator slings, the former was superior for both objective (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.05-1.54) and subjective (OR, 1.23; 95% CI, 1.02-1.48) cures. Between minislings versus other slings, there was a difference favoring other slings for subjective cure (OR, 0.58; 95% CI, 0.39- 0.86). Between pubovaginal sling versus Burch surgery, there was a difference for both objective (OR, 2.04; 95% CI, 1.50-2.77) and subjective (OR, 1.64; 95% CI, 1.10-2.44) cures, favoring pubovaginal sling. Therewas no difference in the groups: midurethral slings versus Burch, pubovaginal sling versus midurethral slings, transobturator slings, minislings versus other slings (objective cure). Retropubic and pubovaginal slings are more retentionist. Retropubic slings have more bladder perforation, and transobturator slings, more leg and groin pain, neurological lesion and vaginal perforation. Conclusion Pubovaginal slings are superior to Burch colposuspension surgery but exhibit more retention. Retropubic slings are superior to transobturator slings, with more adverse events. Other slings are superior to minislings in the subjective aspect. There was no difference in the comparisons between midurethral slings versus Burch colposuspension surgery, pubovaginal versus midurethral slings, and inside-out versus outside-in transobturator slings.

Assessing the Readjustable Sling Procedure (Remeex System) for Female Stress Urinary Incontinence With Detrusor Underactivity / 대한배뇨장애요실금학회지

PURPOSE: Many surgeons worry about postoperative voiding problems in patients with stress urinary incontinence (SUI) and detrusor underactivity (DU). This study hypothesized that adjusting the tension after surgery would benefit patients with DU, and therefore researchers evaluated the outcomes and quality of life of women with SUI and DU who underwent the readjustable sling procedure (Remeex). METHODS: The medical records of 27 patients who were treated with the Remeex system for SUI and DU between 2007 and 2013 were retrospectively analyzed. The incontinence visual analogue scale (I-VAS), incontinence quality of life questionnaire (I-QOL) and the Sandvik incontinence severity index (ISI) were used to evaluate the efficacy of the Remeex system both prior to surgery and at the last visit after surgery. The treatment was considered successful if there was no urine leakage based on the Sandvik questionnaire. RESULTS: The mean follow-up period was 38.0 months (range, 1–75 months), and the treatment success rate was 81.5%. Despite no urine leakage, 7 patients wanted the Remeex system to be removed due to persistent postoperative urinary retention within a year of surgery. One patient underwent a long-term adjustment under local anesthesia 6 years after the initial surgery. The I-VAS, ISI and all domains of the I-QOL scores improved significantly postoperatively and the maximum flow rate decreased significantly after the procedure. However, the postvoid residual did not change significantly. CONCLUSIONS: The Remeex system provided a good cure rate and improved the quality of life of women with SUI and DU. Therefore, the Remeex system should be considered as a treatment option for female patients with concomitant SUI and DU.

Análisis comparativo entre la colocación medio-uretral de malla sintética (cinta vaginal sin tensión [TVT] y cinta a través del músculo obturador [TOT]); en el tratamiento quirúrgico de la incontinencia urinaria de esfuerzo en mujeres en un período de tiempo de 3 años (2009-2012) / Comparative analysis between the mid-urethral synthetic tape (tension-free vaginal tape [TVT] and transobturator tape [TOT]); in the surgical treatment of stress incontinence in women in a three-year period (2009 ­ 2012)

Introducción: la incontinencia urinaria de esfuerzo es la pérdida involuntaria de orina debido al aumento de presión intra- abdominal. El abordaje vaginal por cinta mediouretral es actualmente el método quirúrgico de elección para el tratamiento de IUE con las técnicas: cinta vaginal sin tensión (TVT) y cinta a través del músculo obturador (TOT). Objetivo: determinar la eficacia y complicaciones observadas after the placement of synthetic midurethral sling for the surgical treatment of urinary incontinence in a period of 3 years at HCAM. posterior a la colocación mediouretral de malla sintética TVT y TOT en el tratamiento quirúrgico de la incontinencia urinaria de esfuerzo en un período de 3 años en el HCAM. Materiales y métodos: se realizó un análisis retrospectivo en pacientes que fueron sometidas a cirugía con la colocación de malla mediouretral para IUE en el HCAM. 218 pacientes fueron estudiados, se registraron datos clínico-demográficos, perioperatorios, transoperatorios, y del seguimiento postoperatorio incluidas complicaciones y mejoría clínica de la IU para evaluar la eficacia y seguridad de los métodos. TVT en la apreciación subjetiva y objetiva de la mejoría clínica (87% vs 82% y 92% vs 90% respectivamente). La perforación vesical se presentó en el 14% en el grupo TVT vs 0.5% del grupo TOT. Complicaciones graves que llevaron a reoperación se presentaron mayoritariamente en el grupo TVT (4.8% vs 2.25% / p= 0.356). Conclusiones: comparativamente, ambas técnicas mostraron similar eficacia a través del tiempo de estudio. Sin embargo TOT tendría menos complicaciones, especialmente en referencia a la perforación vesical. Además, TVT requirió mayor tiempo operatorio, estancia hospitalaria.

Introduction: stress urinary incontinence is the involuntary loss of urine due to increased intra-abdominal pressure. The vaginal approach using midurethral slings is now the most common surgical method for the treatment of SUI with two main techniques: tension free vaginal sling [TVT] and transobturator midurethral sling [TOT]. Objective: to determine the efficacy and complications observed after the placement of synthetic midurethral sling for the surgical treatment of urinary incontinence in a period of 3 years at HCAM. Materials and methods: a retrospective analysis was performed in patients who underwent surgery with placement of midurethral sling for the surgical treatment of SUI at HCAM. 218 patients were studied; clinical-demographics, perioperative, intraoperative, and postoperative complications including monitoring data and clinical improvement of SUI were recorded to assess the efficacy and safety of methods. Results: the TOT group prevailed in effectiveness with no statistically significant difference with respect to the TVT group in assessing subjective and objective clinical improvement (87% vs 82 % and 92 % vs 90 % respectively). Bladder perforation occurred in 14% in the TVT group vs. 0.5 % of the TOT group. Severe complications leading to re operation were mainly presented in the TVT group (4.8 % vs 2.25 % / p=0.356). Conclusions: comparatively, both techniques showed similar efficacy over time of study. However TOT would have fewer complications, bladder perforation being the most important. In addition, TVT required longer operative time, hospital stay.

The Changes of Voiding Pattern After Midurethral Sling Between Pure Stress Urinary Incontinence and Stress Urinary Incontinence With Overactive Bladder Group

PURPOSE: The purpose of this study is to compare changes in voiding pattern after midurethral sling surgery (MUS) between the stress urinary incontinence (SUI) group and the overactive bladder (OAB)+SUI group. MATERIALS AND METHODS: From January 2008 to February 2011, a retrospective survey was conducted of 225 female patients who had been diagnosed with SUI and undergone MUS. The subjects were divided into the SUI group and the OAB+SUI group. Changes in the overactive bladder symptom score (OABSS) and American Urological Association-Symptom Index (AUA-SI) before and three months after the MUS were compared. RESULTS: Of the 225 patients, 165 patients (73.3%) were classified as SUI group, and 60 patients (26.7%) were classified as OAB+SUI group. The mean age of the subjects was 54.7 years (range, 31-80 years), and the mean age of patients was 53.9 years (range, 34-80 years), and 56.8 years (range, 31-78 years) in the SUI group and OAB+SUI group. In SUI group, voiding symptom and storage symptom among the AUA-SI were significantly increased (p<0.05). OABSS were slight increased, but was statistically insignificant (p=0.847). In OAB+SUI group, voiding symptom score and OABSS showed a significant increase (p<0.05), but storage symptom score showed an insignificant increase (p=0.790). CONCLUSIONS: OAB may occur in approximately 18% of SUI patients who undergo MUS surgery, and voiding dysfunctions with deteriorated voiding symptom and storage symptom may also occur. The deteriorated OAB was shown in 45% of SUI patients with OAB after the surgery.

Management of Complications After Tension-Free Midurethral Slings

Since their introduction in 1996, tension-free midurethral slings (MUS) have been proven to have long-term efficacy and safety. They are considered the gold standard treatment of female stress urinary incontinence, especially in cases that are associated with urethral hypermobility. However, they are not free of complications and, although rare, some of these complications can be challenging for both patients and physicians. Some complications occur intraoperatively, whereas others appear in the early or late postoperative period. There is less controversy in the diagnosis and treatment of complications such as vaginal extrusion or urinary system erosion, whereas de novo voiding problems are at best not completely understood. Voiding dysfunction after MUS placement may vary in a wide range from urinary frequency or urgency to retention and is usually attributed to the obstructive or irritative effect of the sling. However, present urodynamic criteria for the diagnosis of female infravesical obstruction are not satisfactory, and the best management policy for de novo voiding dysfunction remains controversial. In the majority of cases, the diagnosis of obstruction leading to a urethral release surgery depends on a combination of several clinical findings. The timing of urethral release surgery varies depending on the preferences of the surgeon, and the outcome of this surgery is not always predictable. The purpose of this review was to assess the diagnosis and management of the immediate, short-term, and long-term complications of MUS in light of the current literature in an attempt to determine the best management policy.

Preoperative Factors Predicting the Outcome of a Midurethal Sling Operation for Treating Women with Mixed Incontinence / 대한비뇨기과학회지

PUPPOSE: We wanted to investigate outcomes after midurethral sling(MUS) operations for treating women with mixed urinary incontinence(MUI) and we wanted to identify the factors for achieving a favorable outcome. MATERIALS AND METHODS: The retrospective data was collected for 279 women with MUI and who underwent a MUS operation with at least 2 years follow up. The following measures were recorded before MUS: a disease-specific validated questionnaire, 1-hour pad tests, standardized stress tests and urodynamic study. The patients were divided as followed; a predominance of bothering symptoms(stress-predominance, urgency-predominance) and the presence of detrusor overactivity(DO). The patients with DO were further classified into the high detrusor pressure (HPDO) group and the low pressure(LPDO) group with a reference level of 15cmH2O of maximum detusor pressure at which involuntary contraction occurred during filling cystometry. The patient's postoperative global impression of improvement, the Bristol Female Lower Urinary Tract Symptom(BFLUTS) score, improvement of stress incontinence(SUI) and urgency were analyzed. RESULTS: The overall success rate of SUI was 96.4%. The predominance of bothering symptoms or the presence of DO did not influence the over all SUI success rate. In a subgroup of women with DO, those women with LPDO showed a significantly higher SUI cure rate than those with HPDO. Urge incontinence resolved in 176(63.1%) and it improved in 60(21.5%), while it was aggravated or it persisted in 43(15.4%). Women with stress- predominant MUI, DO and LPDO experienced better resolution of urgency incontinence, an improved quality of life(QoL) and a higher global impression of improvement. CONCLUSIONS: Our results suggest that women with stress-predominant MUI and without DO or with LPDO are more likely to be cured of their urge urinary incontinence after a MUS operation for treating mixed urinary incontinence.

Causes of Reoperation after Midurethral Sling Procedures in Female Stress Urinary Incontinence

PURPOSE: Midurethral sling procedure has become one of the most commonly performed procedures for the treatment of female stress urinary incontinence(SUI). Although complication rate is very low, some patients are required further treatment to correct unwanted problems after surgery as it continues to be more widely used. We evaluated the mesh-related complications in those who required further procedures after midurethral sling procedures. MATERIALS AND METHODS: From January 2000 to December 2005, female patients who underwent additional surgery because of complications after midurethral sling procedures for stress urinary incontinence were evaluated in this study. RESULTS: In 675 patients, 298 received a tension-free vaginal tape(TVT) and 377 received a Monarc(transobturator route, TOT) as a sling material at 3 different hospitals. 34(5.0%) out of 675 patients required additional surgery to correct complications including obstructive voiding symptoms, mesh extrusion, failed or recurred SUI, wound pain and mesh in the bladder. Mean age of 34 patients was 54.7, and TVT was used in 21(7.0%) out of 298 patients, Monarc was used in 12(3.4%) out of 377 as midurethral sling materials. In 19 patients who showed obstructive voiding symptoms, all were cured by mesh cutting and in 8 patients who complained of immediate recurrence of SUI, 7 showed complete dryness by shortening the loosen mesh. Mesh extrusion with vaginal erosion were observed in 3 and all were cured by segmental resection of mesh without recurrence of SUI. 2 patients who showed recurrence of SUI after 2 years of TVT received Monarc procedure. Mesh in the bladder which was found after 6 months of TVT was managed by endoscopic resection of mesh with Monarc procedure in 1, and suprapubic pain after TVT was improved by resection of TVT segment through suprapubic incision in 1. All reoperation procedures were performed by local anesthesia except 1(mesh in the bladder). CONCLUSION: These data demonstrate that midurethral sling is an excellent surgical procedure with low complication rate, high success rate in reoperation. However, care must be taken to reduce reoperation rate in applying tension of mesh on urethra because most patients(27 out of 34) who required reoperation have complained of obstructive voiding symptoms(19) and persistent incontinence(8).
