title: Peripelvic extravasation and formation of perinephric urinoma after cystoscopy.
abstract: A hitherto undescribed complication of cystoscopy is reported wherein peripelvic extravasation and perinephric collection of urine resulted from conventional cystoscopic examination in a patient with a small-capacity bladder and vesicoureteral reflux. Prompt recognition, institution of indwelling catheter drainage, and massive antibiotic therapy led to spontaneous resolution of the flank mass. In similar cases, we suggest the use of an Iglesias resectoscope with a continuous flow and suction evacuation, even for cystoscopy and bladder biopsy.
