Early postureteroscopy vesicoureteral reflux--a temporary and infrequent complication: prospective study.

BACKGROUND Early complications after ureteroscopy include discomfort, renal colic, urinary infection, and hematuria. Vesicoureteral reflux has been reported as a late complication. The presence of early vesicoureteral reflux after ureteroscopy has not been investigated. METHODS Forty patients were randomly selected for a study in which early vesicoureteral reflux after ureteroscopy was searched for through retrograde cystography. RESULTS In four patients (10%), vesicoureteral reflux was found. Follow-up cystograms 2 weeks after ureteroscopy were normal in all four. CONCLUSION These results suggest that early vesicoureteral reflux after ureteroscopy is rare and that if it appears, it is of low grade and temporary.
