ABSTRACT

INTRODUCTION: Firstly reported in the early 1990s for the treatment of upper urinary tract stones in adult patients, flexible ureteroscopy (F-URS) has been used in children during the past 10 years and is now considered as a viable, but still second-line alternative to extracorporeal shockwave lithotripsy in these patients (ESWL). The aim of this study was to assess the impact of the acquisition of a F-URS on the management of upper urinary tract stones in children. PATIENTS AND METHODS: Data of all ESWL, F-URS and percutaneous nephrolithotomy performed for upper urinary tract stones in children from 0 to 18 years old in a single center from 2000 to 2014 have been collected retrospectively. Patients have been divided into two groups: group 1 before the acquisition of the F-URS (2000-2008) and group 2 after the acquisition of the F-URS (2008-2014). Preoperative data and peri-operative outcomes were compared between both groups using the χ(2) test and Fisher exact test for discrete variables and the Mann-Whitney test for continuous variables. RESULTS: Thirty-seven children have been treated during the first era and 32 during the second one. The two groups were similar in terms of age (7.2 years vs 8.1 years; P=0.54), size of the largest stone (15 mm vs 16.2mm; P=0,56) and number of stones per patient (1.4 vs 2; P=0,07) but the sum of stone diameters was higher in group 2 (16.9 mm vs 24.2mm; P=0,048). The stone-free rates were comparable in both groups (28.1% vs 32.2% after the first procedure; P=0.72), as were the mean number of procedures per patient (2.4 vs 2.5; P=0.78), the total length of stay (2.7 days vs 2.9 days; P=0.77), and the number of patients who experienced at least one complication (37.8% vs 40.6%; P=0.87). CONCLUSION: The acquisition of a F-URS allowed the treatment of more complex stones with a similar efficacy and without increasing morbidity. Further studies are needed to define the role of F-URS in the management of upper urinary tract stones in children.

ABSTRACT

OBJECTIVE: The goal of this prospective study was the evaluation of ambulatory (less than 12h) prostate photoselective vaporisation (PVP) with GreenLight laser XPS. MATERIEL AND METHODS: One hundred and fifteen consecutive patients eligible for ambulatory procedure according to selective criteria (age less than 80, no anticoagulation treatment, no diabetes, patient not alone at home) who underwent ambulatory PVP from 1st May 2012 to 30th June 2013 have been evaluated. The principal criterion was the success rate of ambulatory. Secondary criteria were 3 months functional results and complication rate and satisfaction rate on ambulatory procedure. RESULTS: Around 93.1% patients were successfully treated in ambulatory procedure. The main reason of failure was organizational. There were 2 conversions in monopolar resection and one operative complication. At 3 months, there were 11.5% grade 2 complications with 3.48% rehospitalizations and no reintervention. CONCLUSION: This study demonstrates the feasibility of ambulatory PVP. This procedure should be proposed to selected patients.
