The Utility of Urinalysis Prior to In-Office Procedures

OVERVIEW:

Current urology practice requires every patient to have a urinalysis lab done prior to any
in-office procedures. If the patient's urinalysis is positive, they are then required to have
a urine culture done, which takes 1-3 days to show results, and they may also be prescribed
antibiotics. This practice may cause diagnostic delays, unnecessary cancellations of
procedures, and the overuse of antibiotics. The aim of this study is to assess the usefulness
of urinalysis labs and urine cultures in patients prior to in-office cystoscopies,
intravesical BCG treatments, and prostate biopsies. We predict there is no difference in the
number of cases of urinary tract infections in patients that undergo in-office procedures
with or without a prior urinalysis. We purpose a change in protocol could allow for improved
clinical efficiency, antibiotic stewardship, and be economically advantageous.

OUTLINE:

Participants will be randomly assigned to either receive standard of care before their
procedure or have their procedure conducted by their provider without consulting the
urinalysis results beforehand. Participants will have follow up questionnaires seven days and
thirty days after their procedure.

Inclusion Criteria:

• Patients receiving an in office cystoscopy, intravesical BCG treatment, or prostate
biopsy
