Comparison of Nocturia Response to Desmopressin Treatment between Patients with Normal and High Nocturnal Bladder Capacity Index

Figure 2

Effect of desmopressin therapy according to normal or high pre-treatment nocturnal bladder capacity index (NBCi) on nocturnal polyuria index (NPi), nocturia index (Ni), NBCi, and serum sodium. Each pair: first column—before therapy, second column—on therapy. Pre- versus on-therapy values for NPi and Ni were statistically significantly different with 𝑃<0.0001. NBCi in normal pre-treatment NBCi group remained the same on treatment (𝑃=0.28) and decreased significantly in high pre-treatment group (𝑃<0.0001). Regarding serum sodium, there were no difference between pre-treatment and on-treatment values, for high NBCi group 𝑃=0.93, for normal NBCi group 𝑃=0.066. On therapy, comparison of each two groups showed no significant differences for all four measures.
