Distal ureteral atresia associated with crossed renal ectopia with fusion: recovery of renal function after release of a 10-year ureteral obstruction.
We report on a 10-year-old boy with distal ureteral atresia associated with crossed renal ectopia with fusion. He was admitted with a high fever associated with a urinary tract infection. The diagnosis was established by antegrade and retrograde pyelography. The upper hydronephrotic portion of the kidney, obstructed for 10 years, recovered its function after nephrostomy placement. To our knowledge, this is the first patient whose renal function has recovered despite an ureteral obstruction of 10-years' duration. Therefore, we recommend a transient nephrostomy placement even for far advanced pediatric hydronephrosis, to test for the possibility of functional recovery.
