Since some mechanisms for the development of UPS suggest it may be a form of bladder pain syndrome (BPS) due to the intimate relation of the urethra with the bladder (both covered with urothelium), a combination of intravesical hyaluronic acid and lidocaine plus sodium bicarbonate, the more widely used regimen for BPS in China, is also applied to UPS here in China. However, the symptom relief of the intravesical irrigation won't last long and patients usually report recurrence in 2-3 weeks. Hence, the purpose of this study is to explore whether the electrical pudendal nerve stimulation（EPNS）, which has been proven effective in treating BPS, is more effective than intravesical instillation (intravesical hyaluronic acid and lidocaine plus sodium bicarbonate) in patients with UPS."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1. male or female patients aged 18 - 75\n2.
