Brief Summary

This study evaluates whether routine urinary catheterization is necessary in patients undergoing laparoscopic totally extraperitoneal (TEP) inguinal hernia repair. Urinary catheters are sometimes used during laparoscopic inguinal hernia surgery to empty the bladder and facilitate surgical dissection. However, catheterization may cause postoperative urinary discomfort, dysuria, and urethral pain. Avoiding routine catheterization may reduce these symptoms without increasing the risk of postoperative urinary retention. In this prospective, single-center, randomized controlled trial, 100 patients undergoing laparoscopic TEP inguinal hernia repair were randomly assigned by a lottery-based method to receive either routine urinary catheterization or no urinary catheterization. The primary outcome is the incidence of dysuria on postoperative day 1. Secondary outcomes include urinary or urethral pain, pain severity assessed using a visual analog scale (VAS), postoperative urinary retention, surgical complications, and hernia recurrence. Urinary symptoms and complications are assessed on postoperative days 1, 10, and 30. Hernia recurrence is evaluated during a six-month follow-up period. The study aims to determine whether omitting routine urinary catheterization reduces postoperative urinary symptoms without compromising patient safety.

Outcome Measures

Primary Outcomes (1)

  • Incidence of Dysuria on Postoperative Day 1

    The primary outcome was the incidence of postoperative dysuria, defined as patient-reported pain, burning, or discomfort during urination within the first 24 hours following laparoscopic total extraperitoneal inguinal hernia repair. Dysuria was assessed as a binary outcome (present or absent). The proportion of participants experiencing dysuria was compared between the urinary catheterization and no-catheterization groups.

    Postoperative Day 1 (within 24 hours after surgery)

Secondary Outcomes (10)

  • Incidence of Urinary or Urethral Pain on Postoperative Day 1

    Postoperative Day 1 (within 24 hours after surgery)

Study Arms (2)

No Urinary Catheterization

EXPERIMENTAL

Participants assigned to this group underwent laparoscopic total extraperitoneal (TEP) inguinal hernia repair without routine perioperative urinary catheterization. The surgical procedure was performed under general anesthesia using a standardized technique. Postoperative urinary symptoms, urinary retention, and surgical complications were assessed during follow-up.

Procedure: No Routine Urinary Catheterization

Routine Urinary Catheterization

ACTIVE COMPARATOR

Participants assigned to this group underwent laparoscopic totally extraperitoneal (TEP) inguinal hernia repair with routine perioperative urinary catheterization. A urinary catheter was placed during the perioperative period and removed before hospital discharge, approximately 24 hours after surgery. Postoperative urinary symptoms, urinary retention, and surgical complications were assessed during follow-up.

Procedure: Routine Urinary Catheterization

Interventions

Routine perioperative urinary catheterization was performed in participants undergoing laparoscopic total extraperitoneal inguinal hernia repair. The urinary catheter was maintained during the immediate postoperative period and removed before hospital discharge, approximately 24 hours after surgery.

Routine Urinary Catheterization

Participants underwent laparoscopic total extraperitoneal inguinal hernia repair without routine perioperative urinary catheter placement. Postoperative urinary symptoms and urinary retention were assessed using the same follow-up schedule as the catheterization group.

No Urinary Catheterization

Model Details: This was a prospective, single-center, two-arm, parallel-group randomized controlled trial. Participants undergoing laparoscopic total extraperitoneal (TEP) inguinal hernia repair were randomly assigned using a lottery-based allocation method to either routine urinary catheterization or no urinary catheterization. Both groups underwent the same standardized surgical procedure, and postoperative urinary outcomes were assessed at predefined follow-up intervals.
