Abstract:
Objective To classify patients with pelvic pain and to improve the understanding of etiology and to guide treatment by using a clinical phenotype system (UPOINT) and to examine the relationship between UPOINT and symptoms in patients with interstitial cystitis/painful bladder syndrome. Methods From November 2009 to October 2011,54 IC/PBS patients including 42 female and 12 male patients were treated.The mean age was 41.0 ± 12.4 yrs (range from 21 to 76 yrs).Median symptom duration was 63.0 ± 59.2 months ( range from 6 to 240 months).54 patients with interstitial cystitis/painful bladder syndrome were classified in each domain of UPOINT,that was urinary,psychosocial,organ specific,infection,neurological/systemic and tenderness.Symptoms were assessed using the Interstitial Cystitis Symptom Index,Pain/Urgency/Frequency score and visual analogue scale for pain/urgency/frequency.Clinically relevant associations were calculated. Results In the 54 IC/PBS patients,median ICSI score was 15.0 ± 1.84 points ( range from 9 to 19 points) ; Median PUF was 20.0 ± 2.3 points ( range from 14 to 25 points) ; Median pain associated with bladder score of VAS was 7.0 ± 1.0 points (range from 5 to 10 points).The percent positive for each domain was urinary 100％,psychosocial 44％,organ specific 96％,infection 33％,neurological/systemic 24％ and tenderness 28％,respectively.All patients were included in at least 2 domains,with 2 domains of 11％,3 domains of 38％,4 domains of 36％,5 domains of 13％ and 6 domains of 2％.The number of domains was associated with greater symptom duration ( Spearman r =0.76,P ＜0.01 ) but not age.The number of domains was also associated with poorer general interstitial cystitis and pain symptoms ( Spearman r =0.89,P ＜ 0.01 ) but not with frequency or urgency.The psychosocial domain was associated with increased pain,urgency and frequency,while tenderness was associated with increased ICSI score,PUF score and urgency.The neurological/systemic domain was associated with increased ICSI score while the infection domain was not associated with any increased symptoms. Conclusions The UPOINT phenotyping system can classify patients with interstitial cystitis according to clinically relevant domains.The UPO1NT system can act as the guiding theoretical basis for directing multimodal therapy,it deserves clinical promotion.
