Title: Detrusor myopathy: an accurate predictor of bladder hypocompliance and contracture in interstitial cystitis. Author: Christmas TJ, Smith GL, Rode J. Journal: Br J Urol; 1996 Dec; 78(6):862-5. PubMed ID: 9014709. Abstract: OBJECTIVE: To determine whether any histological characteristics within the detrusor in cases of early interstitial cystitis (IC) predict the subsequent development of severe symptoms due to bladder contracture. PATIENTS AND METHODS: The detrusor muscle component of bladder biopsies from 21 patients with IC was examined in sections stained with haematoxylin and eosin. Videocystometrography was performed at least 2 months after the biopsy and the patients were then followed up clinically for at least 3 years. RESULTS: The detrusor appeared normal in 13 patients; in eight there was evidence of detrusor myopathy. Patients with biopsies confirming detrusor myopathy were significantly more likely to have hypocompliant bladders than those with normal detrusor muscle histology (P < 0.02). Over the following 3 years, six of the eight patients with detrusor myopathy developed progressively severe symptoms and required subtotal cystectomy and enterocystoplasty. None of the 13 patients without detrusor myopathy required bladder substitution. CONCLUSION: In IC, detrusor myopathy is associated with bladder hypocompliance. Patients with detrusor myopathy appear to have more severe disease and are more likely to progress to bladder contracture requiring substitution enterocystoplasty.[Abstract] [Full Text] [Related] [New Search]
