Preoperative Preparation

Patients undergoing laparoscopic management of symptomatic calyceal diverticulum should receive the same preoperative regimen as any laparoscopic renal surgery patient. Bowel preparation consists of a clear liquid diet and one to two bottles of magnesium citrate the day before surgery. In addition, culture-specific antibiotics should be started at least 48 hours prior to surgery. This may require outpatient intravenous dosing or admission to the hospital. In the absence of documented urinary tract infection, a prophylactic intravenous dose of cefazolin is given one hour prior to surgery. All candidates for laparoscopic management of symptomatic calyceal diverticulum should have undergone computed tomography scan to delineate the three-dimensional location and the overlying renal parenchyma of the lesion.
