Sistema masculino transobturador ajustable (ATOMS(R)) como tratamiento de la incontinencia urinaria de esfuerzo secundaria a resección transuretral de la próstata / Adjustable transobturator male system (ATOMS(R)) as treatment of stress urinary incontinence secondary to transurethral resection of the prostate

Objetivos: Estudio de viabilidad para evaluar la eficacia y la seguridad del sistema masculino transobturador ajustable (ATOMS(R)) para la incontinencia urinaria de esfuerzo (IUE) masculina después de la resección transuretral de la próstata. Materiales y métodos: Se implantó ATOMS(R) a 20 pacientes con IUE causada por resección transuretral de la próstata con o sin radioterapia. La severidad de la incontinencia fue evaluada como leve (2 compresas/día), moderada (3-5 compresas/día) o severa (≥6 compresas/día), y se consideró paciente seco aquel sin compresas o con una compresa de seguridad al día. Se investigó el cambio en el recuento de compresas (pad-count) y en el peso de las compresas (pad-test), así como otros parámetros operatorios, la satisfacción del paciente con el procedimiento, y el número y grado de complicaciones (Clavien-Dindo). Resultados: La mediana de edad fue de 76,5 años. Cinco pacientes habían recibido radioterapia pélvica (3 por cáncer de próstata, 2 por cáncer rectal) y 2 (10%) habían tenido esfínter urinario artificial con erosión uretral y fallo mecánico, respectivamente. La IUE preoperatoria fue leve en 4 (20%), moderada en 7 (35%) y severa en 9 (45%). La mediana de relleno del sistema fue de 13,5 ml. La mediana de pad-test disminuyó de 375 ± 855 ml basal a 10 ± 31,5 ml y el pad-count, de 4 ± 3 a 0 ± 1,5 tras el ajuste (1 ± 3 rellenos). La IUE postoperatoria fue leve en 2 (10%) pacientes, moderada en uno (5%) y severa en 2 (10%). La tasa de satisfacción fue del 80%, igual para pacientes con o sin radioterapia previa. Ningún paciente tuvo retención urinaria al retirar el catéter. Hubo complicaciones en 3 (15%) casos, todas menores. Tras una mediana de seguimiento de 38,5meses no se ha retirado ningún sistema; 19 (95%) pacientes se consideran mejor que antes y 11 (55%) muchísimo mejor. Conclusión: Según la eficacia a corto plazo y la satisfacción del paciente, ATOMS(R) puede considerarse una alternativa realista para IUE después de la resección transuretral de la próstata, incluso en pacientes radiados. La ausencia de erosión uretral y la escasez de problemas hacen esta alternativa especialmente atractiva para pacientes con destreza disminuida, edad avanzada y tratamientos previos fallidos

Objectives: Feasibility study to evaluate efficacy and safety of Adjustable Transobturator Male System (ATOMS(R)) for male stress urinary incontinence (SUI) after transurethral resection of the prostate. Materials and methods: Twenty patients were implanted ATOMS(R) for SUI caused by transurethral resection of the prostate with or without radiotherapy. Incontinence severity was evaluated as mild (2 pads/day), moderate (3-5 pads/day) or severe (≥ 6pads/day), and dryness as none or one security pad/day. Changes in pad-test and pad-count after adjustment were investigated, together with operative parameters, patient satisfaction with the procedure, and number and grade of complications (Clavien-Dindo). Results: Median age was 76.5 years. Five patients received previous pelvic radiation (3 prostate, 2 rectal cancer) and 2 (10%) previous failed artificial urinary sphincter with urethral erosion and mechanical failure, respectively. Preoperative SUI was mild in 4 (20%), moderate in 7 (35%) and severe in 9 (45%). Median filling of the system was 13.5 ml. Median pad-test decreased from 375 ± 855 ml baseline to 10 ± 31.5 ml and pad-count from 4 ± 3 to 0 ± 1.5 after adjustment (1 ± 3 fillings). Postoperative SUI distribution was mild in 2 (10%), moderate in one (5%) and severe in 2 (10%). Satisfaction rate was 80%, equal for transurethral resection of the prostate with/without previous radiotherapy. No patient had urinary retention after catheter removal. Complications presented in 3 (15%) patients, all minor. After median 38.5mo follow-up no system has been removed, 19 (95%) self-considered better than before and 11 (55%) very much better. Conclusion: Based on short-term efficacy and patient satisfaction ATOMS(R) can be considered a realistic alternative for SUI after transurethral resection of the prostate, even after irradiation. Absence of urethral erosion and very limited problems make this alternative especially attractive for cases with diminished dexterity, advanced age and previous failed treatments
