Perioperative prophylaxis for percutaneous nephrolithotomy: randomized study concerning the drug and dosage.

Purpose: To compare sulbactam-ampicillin and cefuroxime antibiotics for prophylaxis of percutaneous nephrolithotomy (PCNL) and to find out the optimal regimen for antibiotic maintenance to prevent systemic inflammatory response syndrome (SIRS).

Patients And Methods: Between February 2010 and March 2011, a total of 198 patients in whom PCNL was performed were prospectively randomized into two main groups regarding the type of prophylactic antibiotic (group1: sulbactam-ampicillin, group 2: cefuroxime). Each group was further randomized according to duration of antibiotic maintenance (a: single dose prophylaxis, b: additional dose 12 hours after prophylaxis, c: beginning with prophylactic dose until the nephrostomy tube removal).

Variables that influence operative time during percutaneous nephrolithotomy: an analysis of 1897 cases.

Background And Purpose: Operative time is an important perioperative factor and is related to postoperative complications and procedural cost-effectiveness. There are few studies, however, investigating factors that affect operative time during percutaneous nephrolithotomy (PCNL). In this study, patient and kidney stone-related factors that influence operative time were analyzed.

Is there a difference in outcomes between digital and fiberoptic flexible ureterorenoscopy procedures?

Purpose: We aimed to compare the outcomes of patients who were treated using digital and fiberoptic flexible ureterorenoscopy (urs) for kidney stones.

Patients And Methods: Between September 2008 and December 2009, a total of 76 patients who were treated with either a conventional fiberoptic flexible ureterorenoscope (FFU) (n = 34) or digital flexible ureterorenoscope (DFU) (n = 42) were compared. All procedures were performed by the same surgeon.

Tubeless procedure is most important factor in reducing length of hospitalization after percutaneous nephrolithotomy: results of univariable and multivariable models.

Objectives: To evaluate the effects of kidney stones and patient-related parameters on the length of hospitalization (LOH), which is one important factor affecting the cost effectiveness of percutaneous nephrolithotomy (PCNL). Recently, increases in healthcare costs have highlighted the importance of evaluating the cost effectiveness of a treatment as much as its efficacy.

Material And Method: During an 8-year period, the records of 1669 patients with renal calculi who underwent PCNL were reviewed retrospectively.
