Overview | Diagnosis | Treatment | FAQ
What are the consequences if hydronephrosis isn’t treated?
If the hydronephrosis is mild and asymptomatic, it is generally safe to not treat the condition. On the other hand, if the obstruction is impairing renal function, or causing kidney infection or stones, failure to treat the obstruction may damage the kidney, even if the obstruction is asymptomatic. Further testing is required to determine if the obstruction can be safely observed.
How does is the ureter reattached to the renal pelvis after the UPJ obstruction is excised?
Dissolvable sutures are used to sew the ureter to the renal pelvis. The sutures take a month or longer to dissolve, which allows the tissue to grow back together.
How is the stent removed following an UPJ procedure or endopyelotomy?
A small grasping instrument that is passed through an endoscope is used to remove a stent from the bladder. This procedure is typically performed under local anesthesia in the office. If a stent exits outside the body, the stent is typically removed under x-ray guidance as an outpatient.
