Insights
Ultrasound effectively monitors pelviureteric junction obstruction in infants. Postoperative follow-up shows reduced pyelectasy and maintained renal parenchyma size in most cases.
Area of Science:
- Pediatric Urology
- Medical Imaging
Background:
- Pelviureteric junction obstruction (PUJO) is a common congenital anomaly in newborns and infants.
- Ultrasound is a primary diagnostic tool for evaluating PUJO.
- Management strategies include surgical intervention and nonoperative surveillance.
Purpose of the Study:
- To assess the effectiveness of ultrasound in monitoring infants with pelviureteric junction obstruction.
- To evaluate the outcomes of both operative and nonoperative management of PUJO.
- To analyze long-term ultrasound findings post-surgery.
Main Methods:
- Retrospective analysis of 134 newborns and young infants diagnosed with PUJO via ultrasound.
- Categorization into operative (47 patients) and nonoperative (87 patients) groups.
- Serial ultrasound examinations at 6 and 12 months postoperatively for 35 patients.
Main Results:
- One year after surgery, 77% of patients showed decreased pyelectasy.
- Renal parenchyma size was normal or increased in 91% of cases postoperatively.
- Mild postoperative pelvic dilatation was common but often without signs of obstruction.
Conclusions:
- Ultrasound is a valuable tool for monitoring the resolution of pelviureteric junction obstruction in infants.
- Surgical and nonoperative management can lead to favorable long-term outcomes.
- Postoperative mild hydronephrosis requires careful interpretation to differentiate from persistent obstruction.
Abstract:
134 newborns and young infants were investigated by ultrasound because of pelviureteric junction obstruction. Operation has been performed in 47 babies, 87 patients were followed nonoperatively. The results of the ultrasound studies were elaborated in 35 patients in 6 and 12 months postoperatively. One year after surgery pyelectasy decreased in 77 percent of the cases, the size of the renal parenchyma was normal or increased in the 91 percent of the cases. The postoperative mild dilatation of the pelvis is often observed without any sign of obstruction.
