Ureteral quadruplication associated with ureteral cyst and massive vesicoureteral reflux treated by laparoscopic nephroureterectomy.

BACKGROUND AND PURPOSE: Ureteral quadruplication is an extremely unusual developmental abnormality. We present the eighth reported case but the first to be associated with a ureteral cyst, with massive vesicoureteral reflux that was treated with laparoscopic nephroureterectomy.

CASE REPORT: A 3-year-old boy was evaluated for recurrent urinary-tract infection. Massive left-sided vesicoureteral reflux associated with incomplete ureteral triplication was identified. A DMSA scan disclosed impaired function of this kidney. An uneventful total laparoscopic nephroureterectomy was performed at which a fourth atresic ureter was identified. All the four proximal ureters opened into a large ureteral cyst, and a distal monoureter opened into the bladder.

CONCLUSION

The patient recovered fully and was asymptomatic 6 months postoperatively.
