Renal pelvis-ureteral junction stenosis obstructs the flow of urine from the renal pelvis to the ureter. If not detected and treated promptly, the kidney can be seriously damaged. Laparoscopic surgery is the most effective treatment for renal pelvis-ureteral junction stenosis, in which Robot-assisted surgery is a new surgical approach with many outstanding advantages.

Urethritis in children is a common disease, caused by the growth of bacteria, parasites or viruses in the bladder (where urine is stored) and in the kidneys (where urine is filtered and formed). Urethritis in children can be asymptomatic or only make the child feel tired or can cause very serious complications.

Hydronephrosis due to ureteropelvic junction stenosis is an internal or external narrowing of the junction between the renal pelvis and the ureter. Treatment of hydronephrosis due to ureteropelvic junction stenosis is based on the principle of resolving the damage and preventing complications.

Renal pelvis-ureteral junction stenosis in children is a common urinary tract malformation that obstructs the flow of urine from the renal pelvis to the ureter. If not detected and treated promptly, it can cause dilation of the renal pelvis and serious kidney damage. For children, ultrasound is a safe, non-invasive, non-radioactive diagnostic imaging method and is widely used.
