Total cost per procedure is around 1.85V in a ??2 medium and 9.19V in a saline medium. CONCLUSIONS: Endolithotripsy in a gas medium is safe and gives several advantages in comparison to a saline endolithotripsy. Gas-medium endolithotripsy in convenient for the surgeon because there is no migration of the calculus as there is in a saline. This results in more than 2-fold decrease in operative time. Secondly, CO2 optical properties enhance visualization. Endolithotripsy in a ??2 medium appeared to be more cost-effective. Source of Funding: none
MP22-10 INCREASED THE RISK OF POSITIVE INTRAOPERATIVE URINE CULTURE AFTER URETEROSCOPIC LITHOTRIPSY FOR PATIENTS WITH MILD PYURIA Kuan-Jung Lin*, Yi-Hsiu Huang, Taipei, Taiwan INTRODUCTION AND OBJECTIVES: We evaluated whether the risks of positive intraoperative urine culture will be increased in patients with mild pyuria before ureteroscopic lithotripsy (URSL) in a prospective study. METHODS: We prospectively enrolled patients receiving URSL from 2011/5 to 2015/10. The patients with normal urine routine (sediment WBC ¼5/HPF) before URSL were assigned as control, and those with mild pyuria (sediment 5/HPF < WBC ¼50/HPF ) as experimental group. Febrile UTI, patients < 18 years, pregnant, and urine sediment WBC > 50/HPF were excluded. All patients received same protocol of preoperative and postoperative antibiotics. Pre-, intra-operative culture and post-operative urine routine were collected. Peri-operative data were compared. Post-operative pyuria, febrile episodes, and percentage of emergency room visits were also compared. RESULTS: 218 patients were enrolled (experimental: 93, control: 125). Mean age was 57.3 and 55.1 years, respectively. Patient’s BMI, stone laterality, stone location, and percentage of male patients were similar in both groups. The mean stone size was 0.88cm vs. 0.74cm (p¼0.018). The operation duration was 56.0 vs. 57.8 min (p¼0.009). The stone free rate was 92.4% vs. 89.6%(p¼0.467). The incidence of positive urine culture during the operation was 14.7% vs 5.1%(P¼0.047). However, the incidence of significant bacteriuria (>10^5 CFU/mL) was 2.9% and 1.3%(P¼0.474). Three patients (3.2%) in the experiment group and one (0.8%) in control group had postoperative fever but didn’t reach statistical significance (p¼0.187) CONCLUSIONS: The incidence of positive intraoperative urine culture increased in patients with mild pyuria before URSL. However, the incidence of significant bacteriuria and post-operative fever did not increased in patient with mild pyuria before URSL. Source of Funding: none
MP22-11 SAFETY AND SURGICAL OUTCOMES OF PERCUTANEOUS NEPHROLITOTOMY IN PATIENTS WITH POOR RENAL FUNCTION. Alexander Heinze*, Miguel Villalobos, Eduardo Cruz-Nuricumbo, Lizzette Gomez de Regil, Rodrigo Suarez-Ibarrola, Carlos Otilio García nez, María Teresa del Carmen Moreno y Suarez, Eddie NojJime Moreno, Merida, Mexico; Maria Dolores Alsina, Joey Piccolo, rida, Mexico Kassandra Oliva, Me INTRODUCTION AND OBJECTIVES: Percutaneous nephrolitotomy (PCNL) is today’s standard of care for patients with kidney stones >20mm. Recently studies have been focused on preventing complications and predicting surgical outcomes. Urolithiasis is frequently associated to chronic kidney disease due to its obstructive and infectious implications. The glomerular function rate (GFR) can be calculated from various formulas and is used to evaluate renal function and be staged accordingly (KDIGO, Kidney Disease Improving Global Outcomes).
