Tratamiento de la incontinencia urinaria de esfuerzo con cinchas suburetrales: experiencia en el hospital universitario de Caracas / Treatment of urinary incontinence with girths suburethral: experience at the hospital universitario de Caracas

Objetivo: Describir la experiencia en el tratamiento de la incontinencia urinaria de esfuerzo con cinchas en las pacientes de la Unidad de Patología de Piso Pélvico del Hospital Universitario de Caracas. Métodos: Estudio retrospectivo y descriptivo. Se incluyeron pacientes con diagnóstico clínico y urodinámico de incontinencia de esfuerzo, intervenidas con cincha transobturatriz y minicinchas entre enero de 2010 y diciembre de 2011, con seguimiento durante 12 meses (N=81). Resultados: Edad promedio: 54,9 años, índice de masa corporal promedio: 27,6 kg/m2. El 77,7 % presentaba prolapso de órganos pélvicos. La incontinencia de esfuerzo tipo I fue la más observada con 45,7 %. El 76,5 % se trataron con cinchas y el 23,5 % con minicinchas. La complicación más frecuente fue la infección urinaria baja (17,7 %), seguida de la urgencia de novo (16,1 %) y la extrusión (8 %). Se observó 7 % de recidiva. El tiempo quirúrgico fue 10,8 y 7,8 minutos para cinchas y minicinchas respectivamente. La cura objetiva fue de 93 % y la cura subjetiva osciló entre 93,8 % y 100 % al año de seguimiento para las cinchas, mientras que en el caso de las minicinchas la cura subjetiva osciló entre 50 % y 100 % durante el mismo período. Conclusión: El tratamiento de la incontinencia urinaria de esfuerzo mediante cinchas y minicinchas resulta satisfactorio, con baja tasa de recidivas y complicaciones menores.

Objective: To describe the experience of stress urinary incontinence treatment with slings in the Unidad de Patologia de Piso Pelvico of the Hopital Universitario de Caracas. Methods: Retrospective, descriptive study. We included patients with clinical and urodinamic urinary incontinence who were treated with transobturator slings and minislings between January 2010 and December 2011, and had a follow up of 12 months (N = 81). Results: The average age was 54,96 years old, average body mass index was 27.6 kg/m2 and 77.7 % had pelvic organ prolapse. Type I urinary incontinence was the most frequent (45.7 %). Most of the patients were treated with transobturators slings (76.5 %), and 23.5 % with minislings. The most frequent complication was lower urinary tract infection (17.7 %), followed by de novo urgency (16.1 %), and vaginal erosion (8 %). A 7 % of recurrence was observed. The objective cure was 93 % and the subjective cure ranged between 93.8 % and 100 % during 1 year follow up in the slings group. In de minisling’s group the subjective cure ranged between 50 % and 100 %. Conclusion: The treatment of stress urinary incontinence with transobturators slings and minislings resulted satisfactory due to the low risk of complications and few recurrences.

Arc-to-arc mini-sling 1999: a critical analysis of concept and technology

PURPOSE: The aim of this study was to critically review the Arc-to-Arc mini-sling (Palma's technique) a less invasive mid-urethral sling using bovine pericardium as the sling material. MATERIALS AND METHODS: The Arc-to-Arc mini-sling, using bovine pericardium, was the first published report of a mini-sling, in 1999. The technique was identical to the "tension-free tape" operation, midline incision and dissection of the urethra. The ATFP (white line) was identified by blunt dissection, and the mini-sling was sutured to the tendinous arc on both sides with 2 polypropylene 00 sutures. RESULTS: The initial results were encouraging, with 9/10 patients cured at the 6 weeks post-operative visit. However, infection and extrusion of the mini-sling resulted in sling extrusion and removal, with 5 patients remaining cured at 12 months. CONCLUSION: The Arc-to-Arc mini-sling was a good concept, but failed because of the poor technology available at that time. Further research using new materials and better technology has led to new and safer alternatives for the management of stress urinary incontinence.
