The goal of this clinical trial is to guide and promote the clinical application of T-PTNS in promoting the postoperative recovery of urinary storage symptoms in patients with BPH. The main question is to evaluate the effectiveness and safety of T-PTNS in promoting the improvement of postoperative urinary storage symptoms in patients with BPH through a single-center randomized double-blind controlled trial, and to propose standard parameters for use such as frequency and power, and ultimately to establish a standard process of T-PTNS treatment and form a replicable and promotable therapeutic specification. Participants will receive T-PTNS three times a week for 30 minutes every time. T-PTNS will be discontinued after 6 weeks. The study will last for 12 weeks, and subjects will be followed up periodically during the study period by the relevant researchers.
