- Abstract:
- Objectives The purpose of the study was to evaluate the diagnosis, operative treatment and outcome of the neonates prenatally detected severe hydronephrosis due to ureteropelvic junction obstruction (UPJO). Methods The records of seven neonatal patients with 4th grade hydronephrosis were reviewed. The patients were performed IVP or ECT scan, and MRU. All cases were found severe hydronephrosis due to UPJO. 6 cases were performed Anderson-Hynes pyeloplasty. One case was performed puncture nephrostomy. After 38 days , Anderson-Hynes pyeloplasty was performed. Results All cases were follow-up from 6 months to 2 years. All of seven cases were without complications of surgery in the recent period. Routine urine tests were normal, all cases didn’t have urinary tract infections. The size of the renal pelvis detected by ultrasound improved compared with before operation. Renal cortex was thicken post-operation. Conclusions Anderson-Hynes pyeloplasty was safe and effective to neonatal patients. The surgery may be performed early in the neonatal patients with severe hydronephrosis due to UPJO. Ultrasonography was useful for preoperative diagnosis of hydronephrosis and post-operative follow-up.
