Abstract
Introduction

Our aim was to describe the lower urinary tract symptoms (LUTS) and urodynamic findings in Charcot-Marie-Tooth (CMT) disease patients referred to our Urology Department.

Methods

Retrospective study of those patients with CMT disease diagnosed at the Neurology Department of our Tertiary Hospital and referred to our Urology Department since 2008 due to LUTS. We reviewed their clinical charts regarding the age at CMT disease diagnosis, type of CMT disease and the presence of other comorbidities which could cause LUTS. We collected data on the characterization of LUTS, findings of neurological examination and urodynamic findings.

Results

Seven patients were referred to our department due to the presence of LUTS. They were 3 male and 4 female, with median age at the moment of LUTS onset of 55 (29–67) years and median time from the diagnosis of the neuropathy to the onset of LUTS was 14 (1–37) years. Voiding symptoms were referred by 5 patients and urinary incontinence by 3 patients. Two patients presented recurrent urinary tract infection. Six urodynamic tests were performed which showed a neurogenic acontractile detrusor in 2 patients, detrusor underactivity in one patient, a delayed opening time in one patient, a neurogenic detrusor overactivity in one patient and a urodynamic stress incontinence in one patient. In one patient the urodynamic test was normal.

Conclusions

Most of CMT patients with LUTS complained from voiding symptoms. Several urodynamic findings could be observed mostly during the voiding phase. We recommend performing urodynamic tests in CMT patients presenting with LUTS seeking for treatment or in those with related complications.

Resumen
Introducción

Nuestro objetivo fue describir los síntomas del tracto urinario inferior (STUI) y los hallazgos urodinámicos en pacientes con enfermedad de Charcot-Marie-Tooth (CMT) derivados a nuestro servicio de urología.

Métodos

Estudio retrospectivo de los pacientes con CMT diagnosticados en el servicio de neurología de nuestro centro y derivados al servicio de urología desde 2008 por sintomatología del tracto urinario inferior (STUI). Revisamos el tipo de CMT, la edad al diagnóstico, la presencia de comorbilidades que pudieran causar STUI, las características de los mismos, las exploraciones neurológicas y los hallazgos urodinámicos.

Resultados

Se remitieron 7 pacientes ( 3 varones y 4 mujeres) a nuestro servicio por STUI con una mediana de edad al inicio de los STUI de 55 (29–67) años y tiempo medio entre el diagnóstico de la neuropatía y el inicio de los STUI de 14 (1–37) años. Cinco pacientes refirieron clínica de vaciado, 3 incontinencia urinaria y 2 presentaban infecciones urinarias de repetición. Se realizaron 6 estudios urodinámicos, mostrando detrusor acontráctil neurógeno en 2 pacientes, detrusor hipocontráctil en un paciente, retraso en el tiempo de inicio de la micción en un paciente, detrusor hiperactivo en un paciente e incontinencia de esfuerzo en otro paciente. En un caso el estudio fue normal.

Conclusión

La mayoría de los pacientes con CMT y STUI refieren clínica de vaciado, pudiéndose relacionar con alteraciones urodinámicas, la mayoría en la fase de vaciado. Recomendamos la realización de estudio urodinámico en pacientes con CMT que presenten STUI y soliciten tratamiento o presenten complicaciones asociadas.
