For benign prostatic hyperplasia (BPH) patients requiring a Foley catheter, a 16-18 French (Fr) size is typically recommended, as it provides adequate drainage while minimizing urethral irritation and patient discomfort. In cases of significant prostatic enlargement or urinary retention, an 18-20 Fr catheter may be necessary. Always use a catheter with a 5-10 mL balloon (not a 30 mL balloon which is for hemostasis after prostate surgery). When inserting, use generous lubrication and advance the catheter gently until urine returns, then inflate the balloon with sterile water according to manufacturer specifications (usually 5-10 mL) 1. If resistance is encountered during insertion, do not force the catheter as this could cause urethral trauma; instead, consider using a coudé (curved-tip) catheter which can more easily navigate past an enlarged prostate. After placement, secure the catheter to the patient's thigh to prevent traction on the urethra and bladder neck. The management of BPH is complex and requires a comprehensive approach, including pharmacological and surgical treatments, as well as lifestyle modifications 2, 3. However, the choice of Foley catheter size is crucial in minimizing complications and improving patient outcomes.
Some key considerations when selecting a Foley catheter for BPH patients include:
- Using the smallest diameter catheter that provides adequate drainage to minimize urethral irritation and patient discomfort
- Avoiding the use of 30 mL balloons, which are intended for hemostasis after prostate surgery
- Utilizing a coudé (curved-tip) catheter in cases where resistance is encountered during insertion
- Securing the catheter to the patient's thigh to prevent traction on the urethra and bladder neck
- Considering the patient's individual needs and medical history when selecting a Foley catheter size and type 4, 5.
It is essential to prioritize the patient's quality of life, morbidity, and mortality when making decisions regarding Foley catheter size and management for BPH patients. By selecting the appropriate catheter size and type, healthcare providers can help minimize complications and improve patient outcomes.
