Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Bilateral synchronous simultaneous stone surgery

Arm Description

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.

Outcomes

Primary Outcome Measures

Stone free rate
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

Secondary Outcome Measures

Complications
Complications are assessed according to Clavien Dindo classification
Post operative urinary diversion
evaluation of patients whether they have a nephrostomy or a ureteral stent at the end of the operation
Radiation exposure
The cumulative fluoroscopy dose that was emitted during surgery
Hemoglobin level change
The amount of hemoglobin drop during and after surgery
Hospital stay
The amount of days that the patient stayed at the hospital
Residual stone
The diameter of the stones that couldn't be retracted

5. Study Description

Brief Summary
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).
