Contribution bladder biopsy to the study of urogynaecological patient [Contribución de la biopsia vesical al estudio de la paciente uroginecológica]

Background: One of the characteristics of urinary symptoms in women is their lack of specificity. Patients with stress incontinence or urgency, local irritation, infection, distal stenosis or a neoplastic process have very similar symptoms. Objective: Determine the frequency of bladder structural lesions detected by urethrocistoscopy in which we performed bladder biopsies. Material and method: Descriptive, retrospective, analytical study of files and videos of 331 patients treated in Urodifem de Occidente (private Urogynecology Center). Thirty-five biopsies were taken. The statistical analysis was expressed as means standard deviations, ranges, percentages and Fishers test. Results: Patients ages range 30-90 years average 60+13.76. Predominant symptoms were: irritative vesical syndrome 62.8%; pelvic pain 45.71%; urge incontinence 31.4%; hematuria 31.4%; vesical voiding dysfunction 11.4%. Principal endoscopic findings: Urethrotrigonitis; glomerular lesions or Hunner ulcers; vesical trabeculations; tumor or suspect lesions. Histopathologic findings were: Interstitial Cystitis 42.9%; chronic Cystitis 11.4%; Cystitis glandularis 8.6%; Cystitis follicular 11.4%; bladder cancer 5.7%; Vesical Papilloma 5.7%. Conclusions: This study supports the practice of vesical biopsy when lesions other than those from chronic infection are observes in the presence of tumors or suspect lesions
