Abstract:
Objective: To summarize the long-term efficacy and safety of sacral neuromodulation (SNM) in treating refractory interstitial cystitis/bladder pain syndrome (IC/BPS)，so as to provide clinical evidence for this therapeutic approach. Methods: This study retrospectively analyzed the data of 27 patients with refractory IC/BPS treated at our hospital during Jan.2015 and Dec.2021.All patients underwent SNM Ⅱ.The therapeutic effects were evaluated with Global Response Assessment (GRA).The preoperative and postoperative daily urinary frequency，nocturia frequency，functional bladder capacity，O'Leary-Sant score，pelvic pain，urgency and frequency (PUF) score，quality of life (QoL) score，and visual analogue scale (VAS) score were compared. Results: During the follow-up of (55.55±16.33) months，12 patients showed no symptom relief (GRA≤4)，while 15 experienced symptom relief (GRA>4)，resulting in an efficacy rate of 55.56% (15/27).The average daily urination frequency decreased from (28.74±13.84) to (24.74±16.33) times,the O'Leary-Sant score decreased from (30.19±5.35) to (25.63±9.34)，PUF score decreased from (25.63±5.34) to (22.04±8.29)，QoL score decreased from (5.67±0.55) to (4.33±1.57)，and VAS score decreased from (8.04±1.91) to (5.33±3.09)，the differences were statistically significant (P<0.05). No complications such as incision infections or pain at the implant site were observed. Conclusion: SNM is safe and effective for refractory IC/BPS，but there is a risk of long-term failure.Therefore，patients should be discreetly selected.
