Which of the following is the most appropriate method for collecting urine for culture in a case of the type of fistula ‘2’ shown in the photograph ?
A. Sterile speculum.
B. Foley’s catheter.
C. Midstream clean catch.
D. Suprapubic needle aspiration.
The type of fistula ‘2’ shown in the photograph above represents vesicovaginal fistula.
Ureteric catheterisation is the best method of collecting urine for culture in a case of vesico-vaginal fistula. Second best method of collection of urine is supra pubic aspiration, which needs a full bladder and is not possible in this case.
Collection of urine via sterile speculum and midstream clean catch leads to contamination of urine.
So by exclusion, the best answer is collection of urine using a foley’s catheter.
