This study found that endometriosis infiltrating the bladder wall is associated with painful bladder symptoms, and posterior DIE may impair the inferior hypogastric plexus, leading to dysfunctional voiding.

This prospective observational study of 30 laparoscopically confirmed deep infiltrating endometriosis patients investigated the characteristics of lower urinary tract symptoms (LUTS) and preoperative urodynamic findings, comparing posterior endometriosis alone versus posterior plus anterior involvement. It found that 76.7% reported one or more LUTS symptoms and 96.7% had one or more urodynamic abnormalities; patients with anterior endometriosis had higher rates of increased bladder sensation and painful bladder filling than those with posterior disease only. Voiding symptoms, flowmetry impairment, and increased maximum urethral closure pressure were also frequent but were not correlated with specific lesion location. The authors’ major caveat is the small sample size limited to 30 patients and the observational design, without randomization or a non-endometriosis control group. This paper is centrally about endometriosis — it specifically links lesion location (anterior versus posterior DIE) to bladder symptoms and urodynamic abnormalities in laparoscopically confirmed cases.

Abstract

INTRODUCTION AND HYPOTHESIS: Patients with deep infiltrating pelvic endometriosis (DIE) often describe having lower urinary tract symptoms (LUTS). Bladder pain syndrome in women is also often associated with endometriosis. In this study, we aimed to describe the characteristics of LUTS and urodynamic observations in patients with posterior endometriosis versus those with posterior and anterior endometriosis. METHODS: This was a prospective observational study of 30 patients from two gynecologic surgical settings with experience in DIE surgery. All patients underwent preoperative standardized investigation including detailed evaluation of LUTS and urodynamic studies. During surgery, endometriosis locations were recorded and correlated to symptoms and urodynamic observations. RESULTS: Twenty-three patients (76.7 %) had one or more LUTS symptoms and 29 (96.7 %) had one or more abnormalities at urodynamic examination. At surgery, all patients had posterior endometriosis and ten of them also had anterior endometriosis. Patients with anterior endometriosis had increased bladder sensation (90.0 % versus 45.0 %, p = 0.024) and painful bladder filling (70.0 % versus 30.0, p = 0.04) compared with patients with posterior endometriosis only. Voiding symptoms (60.0 %), impairment of flowmetry (30.0 %), and increased maximum urethral closure pressure (90.0 %) were frequent and not correlated with any specific location. CONCLUSIONS: Endometriosis infiltrating the bladder wall is associated with painful bladder symptoms. Dysfunctional voiding suggests an impairment of the inferior hypogastric plexus by posterior DIE. Clinical preoperative evaluation of bladder function should be systematic; urodynamic tests could be of interest in selected patients with DIE. Endometriosis may be a major cause of bladder pain syndrome.

Abstract

Introduction and hypothesis Patients with deep infiltrating pelvic endometriosis (DIE) often describe having lower urinary tract symptoms (LUTS). Bladder pain syndrome in women is also often associated with endometriosis. In this study, we aimed to describe the characteristics of LUTS and urodynamic observations in patients with posterior endometriosis versus those with posterior and anterior endometriosis.

Methods

This was a prospective observational study of 30 patients from two gynecologic surgical settings with experience in DIE surgery. All patients underwent preoperative standardized investigation including detailed evaluation of LUTS and urodynamic studies. During surgery, endometriosis locations were recorded and correlated to symptoms and urodynamic observations.

Results

Twenty-three patients (76.7 %) had one or more LUTS symptoms and 29 (96.7 %) had one or more abnormalities at urodynamic examination. At surgery, all patients had posterior endometriosis and ten of them also had anterior endometriosis. Patients with anterior endometriosis had increased bladder sensation (90.0 % versus 45.0 %, p = 0.024) and painful bladder filling (70.0 % versus 30.0, p = 0.04) compared with patients with posterior endometriosis only. Voiding symptoms (60.0 %), impairment of flowmetry (30.0 %), and increased maximum urethral closure pressure (90.0 %) were frequent and not correlated with any specific location.

Conclusions

Endometriosis infiltrating the bladder wall is associated with painful bladder symptoms. Dysfunctional voiding suggests an impairment of the inferior hypogastric plexus by posterior DIE. Clinical preoperative evaluation of bladder function should be systematic; urodynamic tests could be of interest in selected patients with DIE. Endometriosis may be a major cause of bladder pain syndrome. Similar content being viewed by others
