UPJ obstruction is a congenital narrowing of the ureter or
the small, tube-like structure that carries urine from the
kidneys to the bladder. Using minimally invasive robotic methods,
surgeons are able to perform the reconstructive surgery with
very high precision through four incisions of a half-inch
or less. Operative times with the da Vinci® S
Surgical System, as compared to traditional open pyeloplasty,
have not decreased; but the hospital stay is decreased from
three days to one.
