COMPARISON OF DURABILITY OF DIFFERENT SMALL
BALLOON CATHETERS FOR TRANSANAL IRRIGATION

PURPOSE
Transanal irrigation (TAI) is a well-documented bowel-management therapy in children with neu-
rogenic bowel disorder, anorectal malformation and Hirschprung. In TAI, rectal catheters with an
inflatable balloon is used. However, balloon burst is a frequent complication and may be a traumatic
experience and potentially lead to bowel perforation.
MATERIAL AND METHODS
First, the Navina™Small and Peristeen™Small catheter, respectively, was attached to an electronic
pump blowing air into the balloon. Diameter of the balloon at time of burst was measured. Second,
the respective catheter was put into a rigid plastic tube with a diameter of 46 mm and the balloon
was inflated with an electronic pump. The length of the balloon inside the tube was measured at
balloon burst. Time to burst and pressure at burst were measured in all 30 experiments. Differences
in mean were statistically tested using the Student’s t-test.
RESULTS
The Navina™ Small catheter showed statistically significant higher durability in all measurements
compared with the Peristeen™ Small catheter. Mean (SD) value of diameter, time and pressure at
burst in air were 72.5 (1.1) mm, 19.4 (1.3) sec, 493 (20) mbar and 66.8 (0.6) mm, 10.1 (0.3) sec,
243 (4.3) mbar in Navina™ and Peristeen™ respectively (p<0.001). Mean (SD) value of length, time
and pressure at burst in plastic tube were 8.4 (0.3) cm, 13.3 (1.3) sec, 687 (58) mbar and 7.0 (0.2)
cm, 7.2 (0.2) sec, 377 (16) mbar in Navina™ and Peristeen™ respectively (p<0.001).
CONCLUSIONS
This study shows that catheter balloon durability can differ between TAI systems and that safety with
the catheter balloon can be enhanced. This need to be further investigated in vivo.

PURPOSE
Haemorrhagic cystitis (HC) is a dreaded event after hematopoietic stem cell transplantation
(HSCT). Treatment goals are to preserve life first, followed of preserving the bladder and ultimately
its functionality. There is no standard therapeutic approach for HC. Described treatment options
provide low success rates and are related to potential life-threatening side effects. The aim of this
study was to describe our experience in treatment of HC following HSCT.
