Abstract

Purpose: To compare the incidence and the safety outcomes associated with active stone removal procedure (ASRP) between neurological and non-neurological patients.

Materials and methods: The present study was conducted using the data issued from the French National Health Data Base. All patients that have been hospitalized to undergo an ASRP between January 1 2012 and December 31 2018 were included and allocated to four neurological groups (multiple sclerosis, spinal dysraphism, paraplegia, tetraplegia) and one non-neurological group. The primary outcome was the rate of patients hospitalized at least once to undergo an ASRP over the study period. The secondary outcomes included the type of ASRP performed, the length of hospital stay, the rates of post-operative UTI, of early re-admission and re-treatments. Multivariate logistic regression was used to estimate odd ratios, the four neurological groups being compared to the non-neurological group.

Results: During the study period, 45,745,055 patients were hospitalised, with 151,850 of them presenting with an underlying neurological disease. Among the non-neurological patients, 0.89% underwent an ASRP, while 1.39% neurological patients did. Neurological patients presented with a lower rate of ESWL associated with a higher rate of PCNL, while the length of hospital stay, tthe rate of post-operative UTI, of early re-admission and of re-treatment were systematically increased (p < 0.001), when compared to non-neurological patients, regardless of the type of ASRP considered.

Conclusions: The results presented here confirm and clarify the incidence and the safety outcomes associated with ASRP within the neurological population and advocate for the emergence of a dedicated research field focusing on neuro-urolithiasis.
