Abstract

Purpose

We describe the use of a serous lined extramural tunnel for ureteral reimplantation during augmentation of a neurogenic bladder to prevent reflux.

Materials and Methods

A 46-year-old male C6 spinal cord injury patient presented with a high pressure bladder, detrusor-sphincter dyssynergia and bilateral grade II/III vesicoureteral reflux. Despite maximal anticholinergic therapy and intermittent catheterization, detrussor pressures were between 80 and 100 cm. water at volumes of 100 to 150 cc with consistent leakage between catheterizations. Preoperative ultrasound and voiding cystourethrogram demonstrated moderate bilateral hydronephrosis and a heavily trabeculated bladder. Augmentation cystoplasty with the formation of 3 cm. extramural ureteral tunnels as described by Ghoneim was performed. The serosa of the adjacent limbs of the ileal segment were opposed to form the back wall of a serosal lined tunnel.

Results

At 3 weeks postoperatively a cystogram demonstrated no extravasation or reflux. At 8 weeks an excretory urogram showed prompt function and excretion bilaterally with marked improvement of preoperative hydronephrosis.

Conclusions

Subserosal ureteral tunnels can be used as an alternative antireflux technique during augmentation cystoplasty when ureteral reimplantation is required. Two advantages of this technique include the elimination of staples and avoidance of ischemic problems associated with an afferent intussuscepted nipple valve.
