Analysis of outcomes of tension-free mid-urethral sling procedure in women with mixed urinary incontinence / 北京大学学报(医学版)

Objective: To evaluate the medium and long term outcomes of tension-free mid-urethral sling in the treatment of female patients with mixed urinary incontinence (MUI).Methods: Twenty-six patients who underwent the tension-free mid-urethral sling procedure for MUI from April, 2010 to September, 2016, were followed up.Four of the 26 patients underwent retropubic tension free mid-urethral sling (TVT), and 22 of them underwent transurethral middle obturator sling (TOT).Scales were used in the follow-up, such as urinary incontinence severity score (UISS), detrusor instability score (DIS), incontinence quality of life scale evaluation (I-QOL), Urogenital Distress Inventory short form (UDI-6), and the outcomes before and after the procedure were compared.Results: The mean age was 62 years, with a range of 42-80 years.The mean body mass index (BMI) was 26.82 kg/m2, with a range of 21.48-31.14 kg/m2.The mean follow-up time was 26 months, with a range of 8-69 months.Twelve patients never took M-blockers and the rest 14 patients took M-blockers within two weeks.None of the pa-tients had complications, including dysuria, injury of bladder, urethra, obturator vessel or nerve during the surgery.After pulling out the catheter, no one suffered moderate or severe pain or difficulty of urination.The overall cure rate for stress urinary incontinence (SUI) was 96.15% with 25 patients cured, and for urge urinary incontinence (UUI) was 76.92% with 20 patients cured.The patients'' life quality also improved significantly (P<0.05).Conclusion: Ten of the 26 patients showed an overactive bladder according to urodynamic study, from whom all of the six failed patient were.And 16 patients didn''t show an overactive bladder, which may due to two reasons.One is that their sense of urge is not so serious, the other one is that their sense of urge is from urethra.Proximal urethra is full of nerve, which plays a role in sense and urine control.The sense of urge may come from urethra instead of bladder.Tension-free mid-urethral sling procedure is an effective treatment for women with mixed urinary incontinence.Even without taking the M-blockers, the cure rate for urge incontinence reached 76.92%.The efficacy of surgery remained stable in medium and long term, and the patients'' quality of life improved significantly.

Reconstrucción en osteosarcoma humeral con peroné vascularizado y técnica modificada de tenosuspensión / Reconstruction in humeral osteosarcoma with a vasularised fibula and a modified sling procedure

INTRODUCCIÓN: El osteosarcoma es el tumor óseo maligno más común en la niñez y la adolescencia. Se desarrolla por orden de frecuencia en metáfisis distal de fémur, proximal de tibia y húmero proximal. La variedad de presentación de osteosarcoma telangectásico es rara, y afecta principalmente a niños y adolescentes. Las opciones de tratamiento quirúrgico son cirugía de salvamento y radical. Actualmente la mayoría de los tumores óseos malignos de la cintura escapular pueden seguir la primera opción. OBJETIVO: Presentar una técnica modificada de tenosuspensión para la reconstrucción de defectos humerales en el tratamiento quirúrgico del osteosarcoma de húmero. REPORTE DE CASO: Se presenta el caso de un varón de 16 años de edad con diagnóstico de osteosarcoma telangectásico de húmero tratado con cirugía de salvamento mediante técnica modificada de suspensión con peroné libre vascularizado para la reconstrucción del defecto humeral posterior a resección S345B según la Musculoskeletal Tumour Society (MSTS) y los resultados a 6 y 12 meses. RESULTADOS: A 6 meses del posquirúrgico existió consolidación del injerto sin complicaciones. A los 12 meses no se encontraron complicaciones. Los resultados funcionales fueron del 82 y 86% MSTS, respectivamente. CONCLUSIONES: La técnica modificada de suspensión de hombro utilizando peroné vascularizado y tendón del manguito rotador residual otorga resultados satisfactorios en el caso presentado, sin embargo, se requiere de mayor investigación para considerarla como modalidad de tratamiento generalizado en defectos humerales posterior a resección en bloque como tratamiento quirúrgico.

INTRODUCTION: El osteosarcoma is the most common malignant bone tumour in paediatric patients. The most frequent locations of osteosarcoma are the distal femur, the proximal tibia, and the proximal humerus. Telangiectatic osteosarcoma is rare, most commonly affecting children and adolescents. Surgical treatment options include limb sparing procedures and amputation, with most shoulder tumours currently being able to be treated without amputation. OBJECTIVE: To present a modified sling procedure to reconstruct humeral defects after bone resections in humeral osteosarcoma. CASE REPORT: A 16 year-old male patient with telangiectatic osteosarcoma of the proximal humerus was treated with limb sparing surgery. A modified sling procedure was performed using a vascularised fibular graft to reconstruct the humerus after in-block resection. Results at 6 and 12 months follow up are presented. RESULTS: Graft consolidation was observed at 6 months follow-up, and no complications were observed at 6 and 12 months follow-up. Functional results, according to the Musculoskeletal Tumour Society (MSTS), at 6 and 12 months were 82% and 86%, respectively. CONCLUSIONS: This modified sling procedure using a vascularised fibular graft and rotator cuff tendon showed satisfactory results in this case. Future studies should further evaluate its role in treating humeral defects after in-block resection.

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.

A importância da ultra-sonografia transvulvar na avaliação de parâmetros anatômicos relevantes no tratamento de mulheres com incontinência urinária de esforço / The value of transvulvar ultrasonography in the assessment of major anatomical parameters in the management of female stress urinary incontinence

OBJETIVO: Descrever a importância da ultra-sonografia transvulvar na avaliação das diferenças anatômicas induzidas pelas cirurgias de sling de fáscia lata e tension-free vaginal tape. MATERIAIS E MÉTODOS: Quarenta mulheres com incontinência urinária de esforço, com idades entre 30 e 60 anos, foram tratadas por sling de fáscia lata (20 pacientes) ou tension-free vaginal tape (20 pacientes). A ultra-sonografia transvulvar da junção uretrovesical e da uretra proximal foi a principal ferramenta de investigação pré- e pós-operatória. Os parâmetros estudados foram: distância vertical e distância horizontal da junção uretrovesical, distância pubouretral e comprimento da uretra proximal. RESULTADOS: A distância vertical da junção uretrovesical não variou significativamente após a sling de fáscia lata (p > 0,10). A distância pubouretral e a uretra proximal tornaram-se menores (p < 0,003) e a distância horizontal da junção uretrovesical tornou-se menor só no repouso (p = 0,03) após a sling de fáscia lata. A tension-free vaginal tape diminuiu o deslocamento vertical da junção uretrovesical (p = 0,0005) e o comprimento da uretra proximal (p = 0,02). CONCLUSÃO: A ultra-sonografia transvulvar foi fundamental para documentar que as cirurgias de sling de fáscia lata e tension-free vaginal tape alongam a uretra proximal, sendo a sling de fáscia lata de forma mais eficaz. A sling de fáscia lata enfoca a diminuição da distância pubouretral e a tension-free vaginal tape, o deslocamento vertical da junção uretrovesical.

OBJECTIVE: The aim of this study was to describe the role of transvulvar ultrasonography in the assessment of anatomical changes following fascia lata sling or tension-free vaginal tape procedures. MATERIALS AND METHODS: Forty women in the age range between 30 and 60 years had fascia lata sling (20 patients) or tension-free vaginal tape (20 patients) placement for treating stress urinary incontinence. Transvulvar ultrasonography was utilized, both pre- and post-operatively, as the main investigational tool in these cases for evaluating the urethrovesical junction vertical and horizontal distances, pubo-urethral distance and proximal urethra length. RESULTS: The urethrovesical junction vertical distance did not vary significantly after the fascia lata sling surgery (p > 0.10). Both the pubo-urethral distance and the proximal urethra length became shorter (p < 0.003), and the urethrovesical junction horizontal distance was reduced only at rest (p = 0.03). The tension-free vaginal tape procedure resulted in a reduction of the urethrovesical junction vertical distance (p = 0.0005) and of the proximal urethra length (p = 0.02). CONCLUSION: Transvulvar ultrasonography was of utmost importance in the demonstration that both the fascia lata sling and tension-free vaginal tape surgical procedures elongate the proximal urethra, even though the fascia lata sling technique does it more effectively. The fascia lata sling technique is more focused on shortening the pubo-urethral distance, and the tension-free vaginal tape, on the correction of the vertical displacement of the urethrovesical junction.
