Prospective Study Comparing Lower Urinary Tract Symptoms (LUTS) Before and After Laparoscopic Inguinal Hernia Surgery in Adult Patients With and Without Benign Prostatic Hyperplasia with Repaired Hernia

Abstract

Objective: Benign prostatic hyperplasia (BPH) is the most prevalent cause of bladder outlet obstruction in elderly males. The occurrence of both inguinal hernia and BPH with lower urinary tract symptoms increases with age. This study is aimed at comparing lower urinary tract syndrome using the International Prostate Symptom Score (IPSS) before and after laparoscopic inguinal hernia surgery.Material and Methods: This prospective study was conducted at Somdech Phra Pinklao Hospital. Thirty-five patients who presented with lower urinary tract symptoms (LUTS) and underwent inguinal hernia repair were selected according to inclusion criteria and evaluated using an IPSS scoring chart for urinary symptoms before and after an operation.Results: Thirty-five patients who presented with LUTS symptoms and underwent inguinal hernia repair between 1 December 2020 and 30 November 2021 were included in the study. Statistical analysis by Wilcoxon Signed-Rank test for the 35 patients resulted in an average IPSS that was compared at 2 weeks with a preoperative score of 6.54 and postoperative score of 4.69 (p-value<0.001), preoperative obstructive score of 2.6 and postoperative score of 1.51 (p-value<0.001), preoperative irritative score of 3.94 and postoperative score of 3.17 (p-value<0.001). At 4 weeks, there was an average preoperative IPSS score of 6.54 and postoperative score of 3.86 (p-value<0.001), preoperative of obstructive score of 2.6 and postoperative score of 1.03 (p-value<0.001), and preoperative irritative score of 3.94 and postoperative score of 2.83 (p-value<0.001). At 8 weeks, there was an average preoperative IPSS score of 6.54 and postoperative score of 3.49 (p-value<0.001), preoperative obstructive score of 2.6 and postoperative score of 0.80 (p-value<0.001), and preoperative irritative score of 3.94 and postoperative score of 2.69 (p-value<0.001).Conclusion: Comparison of LUTS before and after laparoscopic inguinal hernia surgery showed a significant decrease in the IPSS score after laparoscopic surgery inguinal hernia at 2, 4 and 8 weeks for both obstructive and irritative scores.
