Study Arms:
- NT prior to PCNL (Type: EXPERIMENTAL): A bladder urine culture will be obtained prior to nephrostomy tube placement and antibiotic treatment will be initiated if necessary. A nephrostomy tube will be placed at least one week prior to surgery in the Vascular Interventional Radiology (VIR) suite under fluoroscopic or ultrasound guidance. The type of imaging will be determined by the radiologist at the time of procedure and documented. A renal pelvis urine culture will be obtained at the time of nephrostomy tube placement. If the culture is positive, the patients will be treated with appropriate antibiotics for at least one week prior to PCNL. If the culture is negative, the patient will be stratified into 2 groups:~1. Hydronephrosis present and/or stone greater than 2cm empiric antibiotics will be initiated.~2. If neither of the above criteria (a.) are met, and the urine culture is negative, no antibiotics will be administered except peri-operatively according to standard protocol.
- NT at the surgery (Type: NO_INTERVENTION): A bladder urine culture will be obtained prior to surgery and appropriate antibiotic treatment will be initiated if necessary. The nephrostomy tract will be placed at the time of surgery under fluoroscopic guidance. All patients will receive empiric intravenous peri-operative antibiotics at induction. Renal pelvis urine and stone will be collected for culture and post-operative treatment will be initiated if necessary.

Based on this trial design, predict the completion outcome and termination type (if applicable).
