Bilateral Synchronous Simultaneous Stone Surgery

August 3, 2023 updated by: Marmara University

Evaluation of Efficacy and Safety Profile of Bilateral Synchronous Simultaneous Stone Surgery for Kidney Stones

Advancements in technology and endourological armamentarium provides multiple surgical options for complicated stone patients. To avoid multiple operations and shorten the total operation durations, bilateral synchronous simultaneous stone surgery (BSSSS) has been popularized in recent years.

Our aim is to evaluate the preliminary outcomes of BSSSS in patients undergoing supine percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Bilateral synchronous simultaneous stone surgery
Patients who will be operated for kidney stones at both their kidneys in a single surgery session will be included in the study. Patients will undergo percutaneous nephrolithotomy for one side and flexible ureteroscopy for the other side.
Patients undergoing Bilateral synchronous simultaneous stone surgery (one kidney undergoing percutaneous nephrolithotomy, other kidney undergoing ureteroscopy at the same time in a single patient)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Stone free rate
Time Frame: at the 24th hour of the surgery
stone free status is decided according to both the immediate evaluation of the endoscopic view at the end of the operation and the post operative imaging with kidney, ureter, bladder X-ray at the 24th hour of the surgery
at the 24th hour of the surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Complications
Time Frame: at the 1st week of surgery
Complications are assessed according to Clavien Dindo classification
at the 1st week of surgery

Time Frame: at the 24th hour of surgery
evaluation of patients whether they have a nephrostomy or a ureteral stent at the end of the operation
at the 24th hour of surgery
Radiation exposure
Time Frame: At 1st hour of surgery
The cumulative fluoroscopy dose that was emitted during surgery
