Abstract: | A 7-year-old girl underwent a prone, retroperitoneoscopic left upper moiety heminephroureterectomy for a non-functioning upper moiety associated with a dilated, ectopic ureter. The dilated ureter was noted prenatally, but postnatal investigations failed to demonstrate the duplex system. The child remained asymptomatic until she represented at 6 years of age, with dribbling of urine. She went on to have an ultrasound scan, dimercaptosuccinic acid and magnetic resonance urogram, which identified a grossly-dilated fluid-filled structure in proximity of the left kidney, but failed to demonstrate the small non-functioning left upper moiety. A computed tomography urogram was more helpful in establishing the diagnosis. Retroperitoneoscopy via three 5-mm ports allowed clear visualisation of both the left duplex ureters, as well as the small non-functioning upper moiety, which had been challenging on the pre-operative imaging. The procedure is described in the accompanying video. The child was discharged home the following day and has been completely well and dry at 6 months' follow-up. |
