Abstract: Urinary tract obstruction symptoms as the predominant manifestation of interstitial cystitis/bladder pain syndrome (IC/BPS) are uncommon and can easily be misdiagnosed as bladder neck obstruction, benign prostatic hyperplasia, or prostatitis. This article reports three cases of such patients. Case 1 was a 61-year-old male, case 2 was a 53-year-old female, and case 3 was a 26-year-old male. Cases 1 and 2 were initially suspected of having bladder neck obstruction, and both underwent bladder neck incision, which resulted in poor outcomes. Case 3 was initially diagnosed with chronic prostatitis. All three patients were diagnosed with IC/BPS after undergoing bladder hydrodistention therapy. One patient received intravesical botulinum toxin A injection following hydrodistention. After treatment, the patients were followed up for 4 months, 2.5 months, and 1.5 months, respectively, and all reported satisfactory symptom improvement.
