Systems and methods for performing, assessing, and adjusting neuromodulation therapy are disclosed herein. One method for assessing the likely efficacy of neuromodulation therapy includes positioninga neuromodulation catheter at a target site within a renal blood vessel of a human patient and obtaining a measurement related to a diameter of the renal blood vessel via the neuromodulation catheter.The method can further include determining a diameter of the renal blood vessel at or near the target site based on the measurement. In some embodiments, (i) one or more parameters of neuromodulationenergy to be delivered to the renal blood vessel can be adjusted based on the determined diameter and/or (ii) the neuromodulation catheter may be repositioned within the renal blood vessel. 本文公开了用于执行、评估、和调整神经调节治疗的系统和方法。用于评估神经调节治疗的可能功效的一种方法包括：将神经调节导管定位在人类患者的肾血管内的目标部位处，以及经由神经调节导管获得与肾血管的直径有关的测量。该方法可以进一步包括：基于测量确定在目标部位处或附近的肾血管的直径。在一些实施例中，(i)可以基于所确定的直径来调整要被递送到肾血管的神经调节能量的一个或多个参数和/或(ii)可以将神经调节导管重新定位在肾血管内。
