To our knowledge this single institution series is the first to include children treated with partial nephrectomy. Pediatric patients with RCC tend to be older and more likely to present symptomatically compared to the typical patient with Wilms tumor. Hematuria and abdominal pain were the most common presentations, and papillary RCC was proportionately more common in this series. Our initial experience suggests that equivalent cure rates can be expected from a nephron sparing approach in appropriately selected cases.

Adolescent males with unilateral left varicocele often demonstrate asynchronous testicular growth that usually equalizes in time. Therefore, sonographic testicular size measurement at a single point during adolescence is insufficient to determine the need for varicocelectomy. When contemplating varicocelectomy we recommend at least 2, and preferably 3, testicular volume measurements 1 year apart to establish accurately decreased left testicular volume compared to a normal right testis.
