Catheterization prior to evacuation of uterus and diagnostic curettage

Dilatation and curettage and evacuation of the uterus are the 2 most common minor gynaecological procedures that trainees perform. Some trainees are taught to catheterize the patient before these procedures. This study was carried out with 2 aims, firstly to establish the prevalence of significant residual urine volume prior to these procedures and secondly to gain information on the practices among members and fellows of the RNZCOG residing in New Zealand with regard to catheterization prior to these operations. The measured residual urine volume was greater than 50 mL in 37.5% of patients and greater than 100 mL in 12.1%. About 92% of those surveyed did not catheterize prior to either procedure. The risk of infection does not appear to be a valid argument for not catheterizing. Routine urinary catheterization before these procedures is unnecessary.
