Résumé

OBJECTIVE: Neurogenic bladders can suffer from overactivity, underactivity or dyssynergia depending on the level of the initial lesion. These symptoms can lead to severe alterations of the upper urinary tract. One of the first-line treatments is the transcutaneous tibial posterior stimulation (TTNS), which was demonstrated to be efficient on urodynamics. But it is an invasive, expensive and sometimes not patient-accepted examination, contrary to the uroflowmetry. The aim of this study is to assess the feasibility of a follow-up with a uroflowmetry when treated by TTNS and show that the maximum flow rate increased after treatment, displaying a better detrusor contraction. METHODS: In total, 38 patients with neurogenic bladder undergoing a 12-weeks TTNS treatment and with 2 uroflowmetries interpretable before and after treatment were included. The maximum flow rate (Qmax), the urinated volume and the post-void residual (PVR) were retrieved from the uroflowmetry, and the USP-score and the urinary discomfort were asked at each appointment. RESULTS: Qmax is increased from 17,53ml/s to 18,26ml/s, as well as the PVR (from 76,97ml to 79,16ml). Urinated volume is decreased from 241,4ml to 193,66ml. Patients feel enhanced after TTNS according to the decrease in the USP-score and the urinary discomfort scale. CONCLUSION: The increase of the cystomanometric capacity and the delay of the detrusor overactivity due to TTNS explains the reduction of the urinated volume and the increase of PVR. Increased Qmax might show a better voluntary bladder contraction, with a restraint due to the lack of abdominal pressure measurement during voiding.
