Are catheters used after hernia surgery?
No, catheters are not routinely used after hernia surgery. A patient with symptomatic benign prostatic hypertrophy may need a catheter after surgery if when he is awake he cannot empty his bladder. Dr. Petersen carries a catheter kit in his truck and has been known to make midnight house calls to put in a catheter. But a catheter is not put in unless it is absolutely needed. Symptoms that may indicate risk for needing a catheter include a slow urine stream, needing to get up several times at night to void and urinary frequency.In my practice the incidence of post operative urinary retention is less than 1%.
