Objective: Through comparing between preoperative and postoperative renal function and shape in children with congenital hydronephrosis, let�s understand the convalescent condition of the postoperative renal function and shape, to decide whether cutting the kidney with hydronephrosis or not.�

Methods: By CTU (Computed Tomography Urography) which possesses high differentiate rate, we determined the change of the preoperative and postoperative renal function and shape of 36 patients.

Results: The preoperative kidneys of 17 patients were developed slowly by IPV check and average preoperative renal parenchyma thickness was 0.4cm by CTU check. The preoperative kidneys of 19 patients were not developed by IVP check, but they were developed by CTU check, though developed slowly and still developed in 24 hours, and average preoperative renal parenchyma thickness was only 0.08cm.The follow-up period was the 6^th month after operation. The postoperative kidneys were developed at the same time with the healthy kidneys by IVP check and were not developed in two hours by CTU. The average postoperative renal parenchyma thickness was 0.8cm. The postoperative renal function and shape recover near to normal.

Conclusions The postoperative renal function and shape in children with congenital hydronephrosis can recover well as long as the preoperative renal function existed. The recovery is obvious in cases with thinner renal parenchyma.
