Pyeloplasty is a plastic surgical procedure at the junction of the renal pelvis to the ureter in patients with scarring (stenoses) causing a significant disruption of kidney outflow.



The causes of these scars can be both congenital and acquired, for example, as a result of inflammations or previous kidney surgeries.


The severity of symptoms depends on the degree of narrowing and the resulting urinary retention. Often, narrowings of the renal pelvis go unnoticed. Affected patients frequently suffer from flank pain, discomfort during urination, or recurrent urinary tract infections

Special Features

For reconstruction, the affected kidney should be functional.
The Da-Vinci pyeloplasty is a robot-assisted, minimally invasive keyhole surgery that requires special surgical expertise. Instruments are introduced under general anesthesia through small abdominal incisions and then controlled by the surgeon via a console.

How is the surgery performed?

During the procedure, obstructive scars at the renal pelvis junction are removed, and a new connection between the renal pelvis and the ureter is established, with an internal ureteral catheter being placed. During this operation, large renal pelvic stones can also be removed.
The success of the operation depends on the team’s experience and specific patient data.

What risks should be considered?

General surgical risks:

Every surgery carries certain risks, such as bleeding during or after the operation, damage to adjacent organs, or wound healing problems.

Patient-specific risks:

Previous surgeries, illnesses, or medications can affect the course of the operation and postoperative recovery. These risks are assessed individually based on the patient’s medical history.

Surgery-specific risks:

Possible side effects include urinary retention, recurrence of scarring obstructing urine flow, inflammations, and urinary tract infections.
After the surgery, which aims at restoring normal urine flow, continuous monitoring of the kidneys is essential. Moreover, a balanced diet, adequate fluid intake, exercise, and sleep support recovery and strengthen long-term health.
