Background: Laparoscopic bilateral inguinal hernia repair may be completed with one large self-fixating mesh crossing the midline. No studies have investigated in detail whether preperitoneal mesh placement induces temporary or more lasting urinary symptoms.
Methods: Urinary and hernia-related symptoms were evaluated preoperatively and postoperatively at 1, 3 and 12 months using the ICIQ-MLUTS questionnaire and EuraHS-QoL score in patients undergoing bilateral inguinal hernia repair.
Results: One hundred patients were included. Voiding symptoms and bother scores were unchanged at 1 or 3 months, but there was significant improvement at 12 months compared with preoperative findings (symptoms P < 0.001; bother score P < 0.01). Incontinence symptoms improved at 1 month (P < 0.05) but not at 3 or 12 months, with a bother score significantly improved at 1 month (P < 0.01) and 12 months (P < 0.01). Diurnal and nocturnal frequency did not change significantly postoperatively, but 12 months nocturnal bother score was decreased (P < 0.05). EuraHS-QoL scores showed statistical significant improvement in all three domains for all measurements at the different follow-up moments compared to previous measurements. Postoperative symptoms were improved at 12 months, compared with preoperative pain scores (- 6.1), restriction of activity (- 10.1) and cosmetic scores (- 4.7) These findings were statistically significant (P < 0.001). At 12 months, there were no patients with severe discomfort (score ≥ 5) for any of the three domains. No recurrences were diagnosed with 95% clinical follow-up at 12 months.
Conclusion: Laparoscopic bilateral groin hernia repair with one large preperitoneal self-fixating mesh did not cause new urinary symptoms and demonstrated significant improvement in voiding symptoms at 12 months. Incontinence and nocturnal bother score were significantly improved.
