In this video, we present the case of a 13-year-old girl presenting with a complicated urological anomaly discovered very late. The lower part of her right kidney is dysplastic (or destroyed) with pseudocystic pyelocalyceal cavities filled with stones and cloudy urine. The first hypothesis is that we are dealing with a true renal duplicity with a destroyed non-functional inferior pole. In this case, there is one ureter per kidney pole. As a result, polar ureteronephrectomy does not cause any potential vascular problems. In this case, thanks to 3D reconstruction (Visible Patient™, a spinoff of IRCAD), it is clear that there is no kidney duplicity, but a pyelic bifurcation. It means that we should manage the only ureter, which drains the superior and inferior pelvis. For that reason, the placement of a double J catheter is essential prior to partial nephrectomy. This catheter should be pulled up until the superior pelvis. Tridimensional reconstruction of the CT-scan images of a patient with a malformation is extremely helpful to better understand the original and unique anatomy of the patient and to determine a tailored operative strategy. This video demonstrates a laparoscopic partial nephrectomy on non-functional, symptomatic right lower pole of the kidney in a 13-year-old girl as an outpatient surgery.
