Retroperitoneal laparoscopy for hydronephrosis due to multiple fibroepithelial polyps: A case series

Abstract We retrospectively reviewed the medical records of four men and one woman who underwent retroperitoneal laparoscopic pyeloplasty for multiple fibroepithelial polyps in a tertiary hospital. The median age of the patients was 30 years (13–39 years). Ispsilateral flank pain was observed in all patients while two patients had hematuria. Preoperative computed tomography urography showed a contrast-enhanced solid mass in the arterial phase and hydronephrosis with images of a filling defect or frond-like in the excretory phase. Length of ureteral segment containing fibroepithelial polyp ranges from 4.3 to 5.6 cm (median, 4.7 cm) The median operation time was 80 minutes (range, 70–90 min) without any complications. Postoperative urine leakage was not observed. Flank pain was resolved in all patients. In addition, hydronephrosis was resolved in two cases and downgraded in three cases. Histopathology revealed fibroepithelial polyp in all cases.
