In patients presenting with perineal pain, quality of life is severely compromised due to the lack of efective analgesic interventions. Tis study aimed to evaluate the efcacy and safety of pudendal nerve pulsed radiofrequency (PRF) for managing perineal pain in IC/BPS patients. Methods: We conducted a retrospective analysis of 51 female IC/BPS patients who underwent pudendal nerve PRF treatment at Peking University People’s Hospital between January 2020 and May 2024 . Terapeutic outcomes were evaluated using validated metrics including the visual analog scale (VAS), interstitial cystitis problem index (ICPI) and symptom index (ICSI), hospital anxiety and depression scale (anxiety: HADS-A and depression: HADS-D), and pain catastrophizing scale (PCS) to comprehensively assess treatment efcacy on perineal pain and associated psychosocial comorbidities.  \nResults: Te VAS score decreased from 8.0 (7.0, 9.0) preoperatively to 4.0 (2.0, 6.0) at 6 months postoperatively (p \u003C 0.0001) . Both ICPI and ICSI scores decreased from 14.0 (12.0, 15.5) and 15.0 (12.0, 18.0) preoperatively to 8.0 (5.5, 11.0) and 8.0 (6.0, 13.0) at  \n6 months postoperatively, respectively (p \u003C 0.0001). HADS-A and HADS-D scores decreased from 8.0 (4.5, 12) and 7.0 (4.5, 11.5) preoperatively to 5 (2.5, 9) and 3.0 (1.5, 7.0) at 6 months postoperatively, respectively (p \u003C 0.05) . Te PCS score decreased from  \n36.58 ± 10.93 preoperatively to 13.46 ± 6.80 at 6 months postoperatively (p \u003C 0.0001) . Te outcomes of pudendal nerve diagnostic blocks showed positive correlations with postoperative improvements in VAS, ICPI, and ICSI at 6 months. A small number of patients experienced transient buttock puncture site pain and acute urinary retention postoperatively, all of which resolved spontaneously without serious adverse reactions.  \nConclusions: Pudendal nerve PRF demonstrates signifcant therapeutic efcacy in managing perineal pain among patients with IC/BPS. Te outcomes of pudendal nerve diagnostic blocks exhibit predictive value for the efectiveness ofpudendal nerve PRF in alleviating IC/BPS-associated perineal pain.  \nKeywords: interstitial cystitis/bladder pain syndrome; perineal pain; pudendal nerve; pulsed radiofrequency  \n1. Introduction  \nInterstitial cystitis/bladder pain syndrome (IC/BPS) is a clinical syndrome characterized by intermittent pelvic and/or perineal pain accompanied by urinary frequency, urgency, and pain during bladder flling. Pathological hallmarks include idiopathic chronic bladder wall infammation and interstitial fbrosis. Epidemiological  \nstudies report a female prevalence of 0.83%–2.71%, approximately 5–10 times higher than males [1] . Te pathogenesis of IC/BPS remains unclear but may involve multifactorial etiologies such as occult infections, bladder mucosal barrier alterations, mast cell activation, autoimmune responses, and peripheral/central neural sensitization [2]","cbCailoFmIp2CRlm","https://ap.wps.com/l/cbCailoFmIp2CRlm","pdf",585703,"English","# Introduction\n# Objectives and Methods\n# Results\n# Conclusions\n# Keywords","[{\"question\":\"What problem does this study address in IC/BPS patients?\",\"answer\":\"It addresses perineal pain in interstitial cystitis/bladder pain syndrome, a refractory condition where patients lack effective analgesic interventions and experience compromised quality of life.\"},{\"question\":\"How was pudendal nerve pulsed radiofrequency (PRF) evaluated?\",\"answer\":\"The study used a retrospective design including 51 female IC/BPS patients who received pudendal nerve PRF, with outcomes measured by VAS, ICPI, ICSI, HADS-A/HADS-D, and PCS.\"},{\"question\":\"What improvements were reported after PRF treatment?\",\"answer\":\"At 6 months postoperatively, VAS, ICPI, ICSI, HADS-A, HADS-D, and PCS scores decreased significantly, indicating reduced perineal pain and improved psychosocial comorbidities.\"}]","Pudendal Nerve Pulsed Radiofrequency Effectively Alleviates Perineal Pain in Interstitial Cystitis/Bladder Pain Syndrome - A Retrospective Study | PDF",1790689961]
