upper pole heminephrectomy
Surgical removal of the upper portion of a duplicated kidney while preserving the lower pole function.
Full Definition
Upper pole heminephrectomy involves surgical excision of the upper moiety in a completely duplicated renal system, typically performed when the upper pole is non-functional or causing complications. The procedure requires careful dissection to preserve the blood supply and collecting system of the functioning lower pole. Common indications include upper pole dysplasia, recurrent infections, or obstruction associated with ureterocele. The technique demands precise anatomical knowledge to avoid injury to the viable kidney tissue. Post-operative imaging confirms preservation of lower pole function and absence of complications.
Usage
Usage note: Specify approach (open, laparoscopic, robotic) and indication when documenting.
