ABSTRACT

Objective To evaluate the diagnostic and therapeutic role in bladder pain syndrome/interstitial cystitis (BPS/IC) of random bladder biopsy and hydrodistention with cystoscopy under anesthesia.Methods A retrospective review of cases in our BPS/IC center was performed from 2005 to 2010. One hundred and nineteen patients were included who are diagnosed as the bladder pain syndrome/interstitial cystitis (BPS/IC).There were 32 male patients,aged 47 to 64 years,and 56 years on average; 87 female cases,aged 23 to 67 years,49 years on average.Patients with bladder pain symptoms underwent a thorough evaluation which include voiding diary,pelvic pain、urgency and frequency questionnaire,urine culture,cytology,acid fast bacilli and upper tract imaging.Cystoscopy and random bladder biopsy had been undertaken with general anesthesia.Before and after hydrodistention with cystoscopy,the patients daily frequency of urination,the maximum urine volume,pain scores,symptom scores,QOL score were observed to understand whether there are significant improvement. Results One hundred and nineteen BPS/IC cases underwent random bladder biopsy and hydrodistention with cystoscopy under anesthesia,and finally 102 cases were confirmed of IC; 17 cases were not IC. Eight patients who were previously diagnosed as BPS/IC were found bladder transitional cell carcinoma as the cause of bladder pain symptoms( including 4 cases carcinoma in situ,1 case Low grade non-invasive bladder cancer,3 cases High grade invasive bladder cancers),and 4 of whom had no hematuria. Mean time from the occurrence of BPS to diagnosis of transitional cell carcinoma was 10.8 months. Three patients previously diagnosed as BPS/IC were found tuberculous cystitis as the cause of symptoms,and one eosinophilic cystitis,three chemical cystitis,two radiation cystitis were also detected.Before hydrodistention with cystoscopy under anesthesia,the daily frequency of urination in 102 cases diagnosed for IC patients was 42.1 ±5.6; the maximum urine volume was 141.0 ± 8.3 ml; pain score 7.6 ± 3.0; O'Leary-Sant questionnaire symptom score was 27.7 ± 4.2; QOL score was 7.6 ± 2.4.After hydrodistention with cystoscopy under anesthesia,the daily frequency of urination in 102 IC patients was 23.3 ± 3.4,and the maximum urine volume was 352.0 ± 1.7 ml ; pain score was 3.3 ± 4.3 ; O'Leary-Sant questionnaire symptom score was 12.5 ± 7.3 ; QOL score was 3.2 ± 5.1. Before and after hydrodistention with cystoscope under anesthesia,all of the daily frequency of urination,the maximum urine volume,pain scores,symptom scores,QOL score in 102 IC patients were significant improved (P ＜ 0.05 ). Conclusions BPS/IC remains a diagnosis of exclusion.Random bladder biopsy and hydrodistention with cystoscopy under anesthesia play an important diagnostic and therapeutic role in BPS/IC.
