Minimally invasive nerve-sparing endometriosis excision improved lower urinary tract symptoms and pain, though some patients developed slow stream and worsened postvoiding residual.

Abstract

OBJECTIVES: The objective of this paper is to evaluate changes in lower urinary tract symptoms (LUTS), severity of pain and urodynamic parameters after minimally invasive nerve-sparing surgery for patients with endometriosis. METHODS: We analyzed 143 patients undergoing minimally invasive nerve-sparing surgery for endometriosis excision (laparoscopy/robot-assisted). The endometriosis was confirmed by preoperative clinical evaluation, magnetic resonance imaging (MRI) showing at least one lesion deeper than 5 mm, and histological confirmation after laparoscopy. We evaluated three points prior and after surgery: LUTS parameters according to the International Urogynecological Association; urodynamic measures of storage and voiding and the severity of the dyspareunia, dyschezia and dysmenorrhea assessed on a self-reported 11-point numeric rating scale. The Wilcoxon signed rank and McNemar tests were used for statistical analyses (p < 0.05). RESULTS: We observed significant improvements in LUTS after the surgery with postoperative symptom-free probabilities in urgency (64.5%), daytime frequency (38.5%), and dysuria (87.1%). However, slow stream prevalence increased significantly postsurgery (p = 0.022), with a 20.5% risk of asymptomatic patients developing this symptom. Urodynamic responses varied; for instance, maximum cystometric capacity improved significantly (p = 0.004), while postvoiding residual worsened (p = 0.006). Significant worsening in postvoiding residual occurred in women with normal preoperative values (p = 0.002), with a 17.7% risk of normal values becoming abnormal. Compliance or maximum cystometric capacity not considered normal preoperatively showed significant improvements (p < 0.001), but the risk of normal values becoming abnormal after surgery was 14.5%. CONCLUSION: The minimally invasive nerve-sparing surgery for endometriosis excision shows improvement in lower urinary tract symptoms, urodynamics parameters and severity of pain. The majority of patients became asymptomatic in the postoperative period. When compared to the benefits of the patients' surgical treatment, particularly when considering the reduction of pain, the risks of the lower urinary tract treatment seem to be acceptable. The surgical intervention seems to be a safe alternative in patients with endometriosis, although studies with larger samples are needed to confirm these findings.
