Prophylactic pre-operative bilateral ureteric catheters for major gynaecological surgery

The use of prophylactic pre-operative bilateral ureteric catheters for major gynaecological surgery is controversial. The aim of this study was to investigate the frequency of ureteric catheter-associated morbidity in our Unit, where systematic pre-operative ureteric catheterisation is performed.

We conducted a retrospective casenote review of 337 gynaecology patients undergoing laparotomy at Salford Royal Hospital between January 2007 and September 2010.

The mean age was 56.36 (range 17–89). Procedures included TAH BSO (n = 249, 74 %), BSO (n = 17, 5 %), radical hysterectomy (n = 36, 11 %), and other (n = 35, 10 %), for indications of ovarian (n = 189, 56 %), uterine (n = 88, 26 %) or cervical cancer (n = 18, 5.3 %), massive fibroids (n = 27, 8 %), severe endometriosis (n = 6, 1.78 %), or other (n = 9, 2.67 %). Bilateral ureteric catheters were attempted in most patients and successfully placed in 315/337 (93 %) patients. In 22 patients (7 %), either no ureteric catheters or a single ureteric catheter was placed due to pre-existing ureteric anomaly, technical difficulty, or surgeon choice. Bilateral ureteric catheterisation took an average of 5.4 min (SD 2.0, range 3.2–9.2) for an experienced consultant or 8.4 min (SD 3.9, range 6.4–18.6) for an SpR trainee to complete. There were no intra-operative ureteric complications. Post-operative complications included urinary tract infection (5/337 patients, 1.48 %), acute renal failure (2/337, 0.6 %), and uretero-vaginal fistulae (1/337 patients, 0.3 %).

Prophylactic pre-operative ureteric catheters are quick and easy to insert and associated with low complication rates. Routine use before major gynaecological surgery can expedite intra-operative identification of the ureters and may reduce accidental ureteric injury.
