Defining recurrence
In adults, at least two episodes within six months or three within a year are commonly used to define recurrent UTI. Dates and culture results help establish the pattern. Frequent burning alone does not prove that every episode has been bacterial infection. [1, 2]
Why cultures and history matter
Assessment considers whether the organism is the same, susceptibility findings, response to treatment and the interval between episodes. Culture confirmation is important in recurrent cystitis. CT or cystoscopy is not automatically needed for everyone; suspected stones, obstruction or another underlying problem guides further investigation. [1]
Symptoms associated with sex
Some people notice episodes after sexual intercourse. Reporting the timing can help the prevention discussion, but it does not mean that every episode is a sexually transmitted infection. Discharge, sores or other new symptoms require separate consideration. Potential contributing factors, including spermicide use, may be discussed. [1]
Prevention is individual
Fluid intake, bladder emptying, menopausal changes and personal risk factors are reviewed. Increased water intake has been studied in some women who previously drank little; this does not justify giving the same fluid target to everyone, particularly those with a fluid restriction. Cranberry and other approaches are considered within the populations and outcomes studied. [1, 2]
Keeping a useful record
A single record can bring together the date, symptoms, culture and treatment for each episode. This turns a general description of frequent infection into a clearer timeline. A new episode with fever, flank pain or systemic illness should not wait for a routine review. Planning to reduce recurrence and assessing an infection occurring now are separate tasks, and the record can help the healthcare team address both.
