NCT00907946 · Status: TERMINATED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 8

No results posted yet for this study

Summary

The investigators are trying to determine whether placement of a nephrostomy tube prior to definitive stone surgery and under ultrasonic or fluoroscopic guidance will reduce complications related to bleeding and infection compare to obtaining renal access at the time of surgery.

Conditions

  • Urolithiasis

Interventions

PROCEDURE

NT 1 day before PCNL

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 day 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.
