PURPOSE: To evaluate outcomes following laparoscopic heminephrectomy (LHN) in duplex kidneys in the pediatric population, focusing on the fate of the remnant moiety.
METHODS: 142 patients underwent laparoscopic heminephrectomy for duplex kidney across 4 different institutions in the U.S. and Europe. Median age at surgery was 11.4 months. A retroperitoneoscopic approach was used in all patients, with 82 (57.7%) patients placed in posterior prone position (PPR), and 60 (42.3%) in lateral retroperitoneal (LRP). Follow up included routine ultrasound, and DMSA was performed in the event of abnormalities in ultrasound or postoperative course.
RESULTS: Median operative time was 120 min. 11 patients (7.7%) required open conversion, the majority of which (8/11) occurred prior to 2000. Median hospital stay was 2 days and no major complications were observed. 7 patients (4.9%) developed a postoperative urinoma, and 1 patient required ureterectomy for urinary tract infection. With a median follow-up of 4.5 years, 7 children (4.9%) experienced significant loss of function in the remaining moiety, with 3 patients requiring completion nephrectomy. Of patients losing their remaining moiety, median age at surgery was 9 months [4 - 42], and all except 1 (6/7) had an upper pole heminephrectomy. Three patients in this group (42%) experienced an immediate postoperative complication (hematoma, UTI, urinoma). No consistent preoperative or technical factors were consistent in the renal loss group.
CONCLUSIONS: LHN for duplex kidney produces satisfactory outcomes in the pediatric population. With a median follow up of 4.5 years, we demonstrate a non-functioning renal moiety rate of 5%. We did not identify any clinical predictors of this outcome in our series, although upper pole heminephrectomy, patient age, and postoperative complications may be contributing factors.
