Beyond The Abstract Long Term Results Of Reconstructive Surgery In Patients With Bladder Pain Syndrome/Interstitial Cystitis: Subtyping Is Imperative
Due to the fact that previous reports on major reconstructive surgery almost consistently have failed to recognize the importance of subclassification, our results1-2 are somewhat difficult to directly compare to others. However, findings that agree with those in the present series are that poor results have often been reported in patients with large preoperative anaesthetic bladder capacity, typically found in patients with non-ulcer disease 3. There are further examples of opposite results in the literature: patients with a supratrigonal bladder resection at the time of augmentation having an excellent outcome 4 as well as persisting symptoms even when the entire bladder and urethra have been removed 5.
The prevalence of the classic Hunner entity versus non-ulcer disease varies considerably between different series, with the classic form generally being reported as being quite uncommon, prevalences ranging from 3,5%-56% in different studies 3, 6-10. If this is due to real demographic differences or difficulties to adequately perform subclassification remains to be determined. In this context, cystoscopy, hydrodistension and biopsies are important. Some maintain that cystoscopic examination provides little useful information11, identifying "only" features typical for the classic subtype of IC and thereby entailing the risk to falsely exclude more than 90% of patients from the diagnosis. Firstly, the crucial importance of identification of Hunner lesions can not be emphasized enough, since this entity is well-defined with special features as to age, endoscopic and histologic presentation, neurobiologic findings, mast cell expression and treatment options, compared to other presentations of BPS/IC 3, 7, 13, 14. Subtyping allows a better chance to tailor an effective treatment at an earlier point of time. Secondly, Hunner's lesions are not the only observation of interest. Apart from glomerulations, the significance of that finding with good reasons being debated, multiple, superficial fissures are additional typical findings of the so-called nonulcer form 14 and should have something to say about the disease. We need objective criteria for the progress of research as well as in clinical practice.
Our study lends further support to the notion that the Hunner type of disease is a quite well defined entity with predictable treatment outcome while the non-ulcer subtype seems to be a generic term for apparently similar but possibly still quite varying conditions.
There is every reason to acknowledge heterogeneity and to find means to more deeply explore this complex.
