Preliminary report of post-Ophira mini sling implantation voiding pattern: What to learn from pressure-flow studies?

BACKGROUND: The study is amined to correlate the voiding pattern after successful mini sling Ophira implantation with postoperative symptoms and satisfaction, in addition to identifying obstructions. MATERIALS AND METHODS: From 2012 to 2015 in a single institution, all consecutive patients who had stress urinary incontinence treated by using the mini sling Ophira had a pre- and 12 months postoperative urodynamic test. The International Consultation on Incontinence Questionnaire - Urinary Incontinence - Short Form (ICIQ-UI-SF) and the International Consultation on Incontinence Questionnaire - Overactive Bladder (ICIQ-OAB) translated into Portuguese, were given. Patients were objectively considered cured when presenting no urinary incontinence at the Valsalva test and subjectively cured when the ICIQ-UI-SF was zero. RESULTS: Questionnaire scores were obtained from 29 patients and urodynamic data from 20 patients. Mini sling Ophira implantation resulted in a significant improvement of urinary symptoms evidenced by a significant mean reduction in ICIQ-UI-SF from 16 to 5 (p < 0.0001) and ICIQ-OAB from 8 to 4 (p = 0.0001). The subjective and objective cure rates were 55% and 45%, respectively. The urodynamic changes were not related to success even when adjusted for age, hormonal status, or anterior pelvic organ prolapse. The mean maximum flow decreased to 4.9 mL/s (95% CI: 0.62-10.8; p = 0.035), and the mean detrusor pressure at maximum flow increased to 11.4 cmH2O (95% CI: 4-18; p = 0.0078). CONCLUSIONS: Mini sling Ophira implantation decreased maximum urinary flow and increased the detrusor pressure at the maximum urinary flow and these urodynamic changes were not related to success.

Banda suburetral libre de tensión transobturadora versus single-incision sling para el tratamiento de la incontinencia urinaria de esfuerzo: seguimiento a 2 años / Transobturator tape versus single-incision sling for the treatment of stress urinary incontinence

Objetivos: Determinar la tasa de curación objetiva/subjetiva y complicaciones del tratamiento de incontinencia urinaria de esfuerzo con banda suburetral transobutadora y single-incision sling. Métodos: Estudio retrospectivo de pacientes operadas de incontinencia urinaria de esfuerzo (hipermovilidad uretral) con banda suburetral transobturadora (n: 37) y single-incision sling (n: 44) entre enero-2012 y enero-2015. Si se asociaba corrección de prolapso de órganos pélvicos, se colocaba banda transobturadora (TVT-O/ TOT) con internación. Si no precisaba corregir prolapso, se insertaba single-incision sling ambulatoriamente. Las evaluaciones fueron al mes, 6 meses y 1 año. El contacto a 2 años fue telefónico. De 37 bandas transobturadoras completaron seguimiento 35 a 1 año y 26 a 2 años. De 44 single-incision sling, completaron seguimiento 42 a 1 año y 19 a 2 años. Resultados: La edad media para transobturadoras fue superior: 65±9,7 vs 58,2±11,3 (p=0,005). Transobturadoras demostraron más prolapso asociado: 87,8% vs 63,3% (p=0,042) y mayor tiempo quirúrgico (minutos): 81,07±31,27 vs 36,79±11,09 (p=0,000). Hubo mayor morbilidad en transobturadoras, sin diferencias significativas. La continencia al año fue: 80% transobturadoras vs 83% single-incision sling (p=0,706) y a 2 años: 84% vs 79% (p=0,623). Se encontraban satisfechas al año: 80% transobutradoras vs 85,7% single-incision sling (p=0,586) y a 2 años: 88,5% vs 78,9% (p=0,512). Conclusiones: Single-incision sling presentan tasas de éxito y satisfacción similares a bandas transobturadoras, con menor morbilidad, coste y tiempo operatorio, pudiendo ser de primera elección cuando no exista prolapso sintomático asociado.

Objectives: To determine objective and subjective cure rate and complications of stress urinary incontinence treatment with transobturator tape and single-incision sling. Methods: We performed a retrospective study including patients diagnosed of stress urinary incontinence, treated surgically either with transobturator tape (n: 37) or with single-incision sling (n: 44), between January 2012 and January 2015. If pelvic organ prolapse was associated, transobturator route was preferred requiring patient hospitalization. If this correction was not needed, we performed single-incision sling, as an ambulatory procedure. Follow up visits were scheduled at 1, 6, 12 months after surgery and a telephone interview at 24 months. Results: Mean age was higher in transobturator group: 65±9.7 vs 58.2±11.3 (p=0.005). A statistically significant difference between the two groups was found in operating time (minutes): 81.07±31.27 vs 36.79±1.09 (p=0.000) and pelvic prolapse associated: 87.8% vs 63.3% (p=0.042). Morbidity rate was higher in the transobturator group, but without significance. After 1 year follow-up, there were no significant differences between the transobturator and the single-incision groups regarding continence (80% vs 83%; p=0.706) and satisfaction (80% vs 85.7%; p=0.586). We found similar results at 24 months telephonic interview. Conclusions: Single-incision slings are comparable to transobturator tapes in 12 and 24 months success rates and satisfaction, with significantly less morbidity, costs and operating time, becoming first line option when no pelvic prolapse is associated.
