Abstract
Introduction

Few studies have been carried out on therapeutic options in patients with painful bladder syndrome associated with interstitial cystitis. The aim is to verify the safety and effectiveness of treatment with sodium hyaluronate through intravesical instillation in patients with painful bladder syndrome.

Materials and methods

A series of 18 female patients is presented, with a mean age of 51 years and prior diagnosis of painful bladder syndrome, who were treated by means of the weekly infusion of an intravesical solution of 40 mg of sodium hyaluronate in sterile solution, over a period of eight weeks. The patients were examined clinically and urodynamically prior to their inclusion in the study and eight months after the instillations had concluded.

Results

There was a statistically significant improvement in the urodynamic parameters and in the symptoms measured quantitatively by means of the questionnaire “Pelvic Pain and Urgency/Frequency” between the baseline situation and after the vesical instillation of sodium hyaluronate in patients with painful bladder syndrome. There was no toxicity arising from the treatment, given that no adverse effects were recorded in relation to it.

Conclusion

The clinical use of intravesical hyaluronic acid in patients with painful bladder syndrome possibly associated with interstitial cystitis has been demonstrated. The clinical improvement is also associated with an increase in the bladder's capacity and sensitivity. Tolerance was excellent. Clinical tests that more profoundly evaluate the therapeutic potential of this drug in this type of patients are required.

Resumen
Introducción

Las opciones terapéuticas en las pacientes con vejiga dolorosa asociada a cistitis intersticial están poco estudiadas. Se pretende verificar la seguridad y eficacia del tratamiento con hialuronato de sodio a través de instilación intravesical en pacientes portadoras de síndrome de vejiga dolorosa.

Material y métodos

Se presenta una serie de 18 pacientes femeninas, con edad media de 51 años y diagnóstico previo de síndrome de vejiga dolorosa, que fueron tratadas mediante la infusión de una solución intravesical semanal de 40mg de hialuronato de sodio en solución estéril, durante 8 semanas. Las pacientes fueron evaluadas clínica y urodinámicamente antes de su inclusión en el estudio y 8 meses después de haber finalizado las instilaciones.

Resultados

Se observó una mejora estadísticamente significativa en los parámetros urodinámicos y en la sintomatología medida cuantitativamente mediante el cuestionario Pelvic Pain and Urgency/Frequency entre la situación basal y después de la instilación vesical de hialuronato de sodio en paciente con síndrome de vejiga dolorosa. La toxicidad derivada del tratamiento fue nula, puesto que no se registró efecto adverso relacionado con el tratamiento.

Conclusión

Se demuestra la utilidad clínica del ácido hialurónico intravesical en pacientes con síndrome de vejiga dolorosa posiblemente asociado a cistitis intersticial. La mejoría clínica se asocia también con aumento de la capacidad y mejora de la sensibilidad vesical. La tolerancia fue excelente. Se necesitan ensayos clínicos que evalúen en profundidad el potencial terapéutico de este fármaco en este tipo de pacientes.
