In the field of gynecology, indwelling catheters are utilized for various reasons: 1. Post-surgical care: After gynecological surgeries such as hysterectomy or pelvic reconstructive surgery, a catheter is often placed to ensure proper drainage of urine. 2. Management of urinary retention: Conditions like pelvic organ prolapse or certain neurological disorders can cause urinary retention, necessitating the use of a catheter. 3. Critical care: In cases of severe illness or during intensive care, a catheter may be required to monitor urine output and manage fluid balance.
