[|Human|] My son was born with hydronephrosis left kidney due to UPJ. He is now 18 months. Initially at birth time AP Diameter was 1.1 then it increased to 2.2 after 7 months. Then AP diameter decreased to 1.5cm when he was around 1 year. We saw different doctors most of them suggested to wait and some suggested surgery. Now he is 18 months old and this month ultrasund report says AP Diameter 2.4 and mild cortical thinning on left kidney. He is healthy and never had any infection/UTI. Should we go for pyloplastry now or wait for more time? is auto recovery still possible or we should consider surgery ASAP. Different doctors have different opinion and we are confused.
[|AI|]  Hi, Since there is already cortical thinning on the kidney I would assume that there is already kidney damage happening because of the UP stenosis. That being said I would get a GFR to be able to determine that kidney function and be able to compare it to the other kidney that is normal. Is there a significant decrease in kidney function then I would think that surgery is warranted at the most appropriate time. Surgery for UP stenosis is a very straightforward surgery it is done almost every day on high volume centers. Recovery is really fast for pediatric patients especially if it's done laparoscopically.  Hope I have answered your query. Let me know if I can assist you further.
