Abstract

We present a case of a 23-year-old male with NF-1 diagnosed with bladder neurofibroma at childhood with regular ultrasound (US) follow-up since then, who presented with an obstructed left kidney. A detailed evaluation including blood tests and advanced imaging revealed left hydroureteronephrosis associated with a large bladder mass. The patient underwent cystoscopy and resection of the left ureteral orifice that was covered by the mass, and an indwelling ureteral stent was left in place. A follow-up US was performed one month after stent removal showing resolution of the hydronephrosis.
