Caesarean sections carry the risk of urinary bladder injury due to formation of adhesions obscuring pelvic planes. Visualizing bladder during retro-fill (cystoinflation) makes it recognizable as it rises into the abdomen taking a tense rounded contour. We conducted a prospective randomized controlled trial to find out whether improved identification of bladder margins by cystoinflation could decrease bladder injury rate and blood loss without causing urological complications. This study included 214 healthy women with previous operative deliveries undergoing elective caesarean section and found to have dense pelvic adhesions. The subjects were randomly allocated into cystoinflation and control groups. Adhesiolysis was performed using bladder retro-fill with 300 cc saline in cystoinflation group, and without retro-fill in control. The bladder injury rate was significantly lower in cystoinflation group compared to control (2.8% vs 20.6%, P < .0001) with lesser blood loss in cystoinflation group (585.33 cc vs 797.10 cc, P < .0001). Mean operative time was similar in both groups. Urinary tract infection and micturition problems occurred more frequently in control group than cystoinflation group (16.8% vs 1.9%, P = .001 and .47 ± 1.63% vs 077 ± .633%, P = .021 respectively) with fistula in one subject compared to none in cystoinflation group. In this study, cystoinflation was effective to significantly reduce bladder injury rate and blood loss. This technique may also prove useful in the fields of surgery, urology and urogynecology.
