Papel de la cistoscopia en el estudio de las pacientes con dolor pélvico crónico: estudio observacional

摘要

Objective: this study was aimed at describing cystoscopy findings in a group of patients suffering from chronic pelvic pain (CPP) who had consulted at a reference clinic in Pereira, Colombia. Materials and methods: a cross-sectional study was made of females who had consulted for CPP at a level 4 hospital and referral center between July 2006 and October 2008 and who had then undergone laparoscopy and cystoscopy. Data was extracted from their clinical histories using a tailor-made form. Interstitial cystitis and chronic trigonitis prevalence were described. Results: 115 females suffering from CPP underwent laparoscopy and cystoscopy under general anesthetic; 59% of the patients had positive cystoscopy findings for interstitial cystitis. Increased urinary frequency, dysuria and nicturia symptoms had a statistically significant correlation with abnormal cystoscopy findings. The main sign found in their physical examination was pain on palpating the bladder. The potassium chloride test had 71% sensitivity and 44% specificity, with 60% positive predictive value (PPV) and 57% negative predictive value (NPV). Conclusions: a high prevalence of interstitial cystitis and chronic trigonitis was found in patients suffering from chronic pelvic pain and urinary symptoms.
