Pyeloplasty is a kidney surgery to reconstruct a malformed or congenitally obstructed ureter connected to the renal pelvis. A robotic pyeloplasty is the precise removal of an obstruction in the ureter leading from one of the kidneys to the bladder (ureteropelvic junction or upj). The UPJ is the portion of the collection system that connects the renal pelvis to the ureter. If the transition from the renal pelvis to the ureter is narrow/tight, the urine will not drain easily. This obstruction leads to progressive dilatation of the renal collecting system and can result in pain and progressive deterioration of kidney function.
Robotic pyeloplasty was developed as a minimally invasive alternative to an open procedure for the treatment of ureteropelvic junction obstruction. Robotic pyeloplasty maintains the advantages of the traditional open technique, while minimizing the risks of a large flank incision. The main advantages of robotic pyeloplasty over traditional open technique are a shorter hospital stay and quick return to daily activities. Unlike open pyeloplasty, the robotic procedure will not leave a large, permanent, disfiguring scar. Robotic pyeloplasty makes suturing of the ureter easier, which makes the procedure safer, as well as effective.
