ABSTRACT

OBJECTIVE 

To report the first performance of simultaneous bilateral percutaneous nephrolithotomy (PNL) and flexible ureteroscopy (fURS) carried out in tandem by two different surgeons in a patient with bilateral medium size renal calculi, describing step by step details of the surgical technique. 

METHODS 

A 46-year-old man, affected with hyperparathyroidism, was diagnosed with asymptomatic bilateral medium size renal stones. An abdominal non-contrast CT scan revealed a left single kidney stone with a maximum diameter of 16 mm and two right renal stones located in the pelvis and in the lower calyx, of 21 and 19 mm in maximum diameter respectively. A bilateral simultaneous PNL on the right side and fURS on the left side was therefore carried out. 

RESULTS

The total operative time was 80 minutes. No intra or post-operative complications were experienced. On post-op day one the creatinine serum level was stable (0.7 mg/dl); he was discharged home 48 hours later. Ureteral stents were removed seven days after the procedure. At two weeks follow-up an abdominal NCCT showed a stone-free status and no changes in renal function were detected.
