Extensive ureteral stricture after percutaneous nephrolithotomy.
OBJECTIVE
To present a previously unreported long term complication of percutaneous nephrolithotomy for exclusive renal stone.


RESULTS
A 30-years-old woman underwent percutaneous nephrolithotomy for a obstructive pelvic stone, through inferior calix access achieving a stone free status. During the procedure occurred an inadvertent pelvis perforation, but the early evolution was otherwise uneventful. Patient was asymptomatic during the follow-up. However, a urinary ultrasound disclosed important pielocalyceal dilation, and further investigation demonstrated extensive proximal ureteral stricture.


CONCLUSIONS
Ureteral stricture may rarely occur as a late complication of percutaneous nephrolithotomy. A review of the literature of this quite uncommon complication was performed and the authors discuss the possible etiology and preventive measures.
