Abstract
Objective

To assess the response of patients diagnosed with painful bladder syndrome to treatment with instillations of sodium chondroitin sulfate.

Material and methods

We present a series of cases of patients with painful bladder syndrome who followed a bladder instillation protocol with sodium chondroitin sulfate, according to our centre's regimen. The response to treatment was assessed with respect to pain, according to the Downie scale; urinary frequency, according to the voiding diary; and subjective improvement, according to the Patient Global Impression of Improvement (PGI-I) scale.

Results

A total of 28 patients with a median age of 59 years (range 22–90) followed this protocol. From the medical histories, 19.4% had suffered an infection of the urinary tract, 3.8% had suffered urinary tuberculosis, 7.6% received pelvic radiation therapy and 26.9% had taken anticholinergic drugs for overactive bladder syndrome. We evaluated the response to treatment at 0, 3, 6 and 12 months and found that at the end of treatment 72.3% of the patients had improved bladder pain and 75% were significantly better.

Conclusions

Treatment with sodium chondroitin sulfate through endovesical instillation in painful bladder syndrome improves pain, voiding frequency and quality of life in the long term.

Material y métodos

Presentamos una serie de casos de pacientes con síndrome vesical doloroso, que siguieron un protocolo de instilación vesical con condroitín sulfato sódico, según el esquema de nuestro centro. Se evaluó la respuesta al tratamiento en lo que respecta a dolor, según la escala de Downie; frecuencia urinaria, según diario miccional y mejoría subjetiva, según la escala de Impresión Mejoría Global de paciente (PGI-I).

Resultados

Veintiocho pacientes con una mediana de edad de 59 años (rango: 22-90) siguieron este protocolo. Entre los antecedentes clínicos el 19,4% había padecido alguna infección del tracto urinario, el 3,8% tuberculosis urinaria, el 7,6% recibió radioterapia pélvica y el 26,9% había tomado anticolinérgicos por vejiga hiperactiva. Evaluamos la respuesta al tratamiento a los 0-3-6 y 12 meses, encontrando que al final del tratamiento el 72,3% había mejorado del dolor vesical y el 75% de los pacientes se encontraba mucho mejor.

Conclusiones

El tratamiento con condroitín sulfato sódico en instilación endovescial en el síndrome de vejiga dolorosa produce mejora del dolor, de la frecuencia miccional y de la calidad de vida a largo plazo.
