Abstract

AIM:

It was believed that neurogenic bladder (NB) might be a risk factor of chronic kidney disease (CKD). However, data are limited regarding the real incidence or risk of CKD in NB. In addition, serum creatinine (sCr), a classical marker of renal function, is not reliable in NB patients because they present muscle wasting due to disuse or denervation. The aim of the study was to estimate the prevalence of CKD in NB patients using serum Cystatin-C. Secondly, we aimed to identify the risk factors for CKD development in NB.

METHODS:

This was a cross-sectional study in a public hospital, a specialized center for patients who were victims of industrial accidents. Serum Cystatin-C was checked at the regular laboratory test in the structured NB programme of the hospital, and 313 patients were included in the study.

RESULTS:

The overall prevalence of CKD, defined as estimated glomerular filtration rate (eGFR) <60/mL per 1.73m2 was 8.0% and 22.4%, by sCr-based and Cystain-C-based eGFR, respectively, and was greater than age-matched general population in Korea. sCr was not able to detect the early deterioration of renal function in NB patients. Co-morbid diabetes, small bladder volume, recurrent urinary tract infection, and proteinuria were significantly associated with CKD in the multivariable analysis.

CONCLUSION:

Chronic kidney disease prevalence was more than three times higher in NB patients than in the general population despite recent progress in the medical care of NB. Co-morbid diabetes, small bladder volume, recurrent urinary tract infection, and proteinuria seem to be the risk factors for CKD development in NB.
