Nephrogenic metaplasia of the ureter. A case report

The authors report a case of nephrogenic metaplasia of the ureter in a 35-y ear-old patient presenting with left low back pain, haematuria and frequenc y. Physical examination was not contributive. IVU showed a piling defect in the left iliac ureter. Ureteroscopy demonstrated a tumour nodule in the le ft iliac ureter. Ureteroscopic biopsy with histological examination showed nephrogenic metaplasia of the ureteric mucosa. Treatment consisted of urete rotomy with resection of the ureteric polyp, followed by closure of the ure terotomy over a double J stent. The course was favourable and postoperative follow-up (IVU, cystoscopy) at 6 months and 12 months was normal.
