Ureteral calculi represent a highly prevalent urological pathology, characterized by the acute onset of intense flank or abdominal pain. This clinical manifestation is often accompanied by hematuria, nausea, vomiting, and ureteral edema1. Currently, surgical intervention, in conjunction with pharmacological management, constitutes the primary therapeutic approach for ureteral calculi. Nevertheless, these conventional treatment modalities are associated with inherent risks, which can lead to significant patient anxiety and reluctance towards undergoing treatment.

Floating Needle Therapy (FNT), alternatively known as Fu's Subcutaneous Needling (FSN), is an innovative minimally-invasive therapeutic technique that integrates traditional acupuncture principles with modern anatomical and physiological concepts. This modality specifically targets the subcutaneous loose areolar connective tissue layer2, demonstrating significant efficacy in the management of pain - predominant functional disorders affecting muscular and myogenic organs. FSN is distinguished by its rapid onset of action, often providing immediate analgesia, favorable safety profile, minimal patient discomfort, and the absence of the need for needle retention. These characteristics render FSN an effective adjunct to conventional therapeutic strategies. Given the muscular - tubular architecture of the ureter, we postulated that FSN could be a viable therapeutic option for the treatment of ureteral calculi.

To the best of our knowledge, this report presents the first documented case of successful FSN treatment for a right distal ureteral calculus in a 53 - year - old male patient presenting with abdominal pain as the chief complaint.
