Comparing extracorporeal shock wave lithotripsy and ureteroscopy laser lithotripsy for treatment of urinary stones smaller than 2 cm: a cost-utility analysis in the Spanish clinical setting.

Purpose: To analyze the efficiency and cost-utility profile of ureteroscopy versus shock wave lithotripsy for treatment of reno-ureteral stones smaller than 2 cm.

Methods: Patients treated for urinary stones smaller than 2 cm were included in this study (n = 750) and divided into two groups based on technique of treatment. To assess the cost-utility profile a sample of 48 patients (50% of each group) was evaluated.

Usefulness of the classification of urinary dysfunction for the prognosis of the first endoscopic treatment of vesicoureteral reflux in children over the age of 3.

Objectives: To assess the diagnostic performance of urinary dysfunction patterns associated with vesicoureteral reflux (VUR) in children over the age of 3 according to the result of the first endoscopic treatment (ENDT1), grouped into a classification designed by our group (CMD.URI-La Fe). Comparison with other current classifications such as that of Van Batavia et al.

[Clinical usefulness of the non-invasive functional study of the lower urinary tract voiding phase as a predictor of resolution after the first endoscopic treatment of vesico-ureteral reflux in children older than 3 years.].

Objectives: To determine the usefulnessof voiding diary (VD), uroflowmetry with electromyography(UF-EMG), bladder wall thickness (before micturition)(VWTUS) and residual urine (PVR) (ultrasound measure)in predicting the outcome of the first endoscopic treatment(1ENDT) of vesicoureteral reflux (VUR) in children> 3 years.

Methods: Cross-sectional ambispective study of 48children with vesicoureteral reflux. Those with previousendoscopic treatment, age or neurological abnormalities and a history of urethralor abdominal surgery were excluded.

3+4 = 6? Implications of the stratification of localised Gleason 7 prostate cancer by number and percentage of positive biopsy cores in selecting patients for active surveillance.

Objective: To determine whether the number and percentage of positive biopsy cores identify a Gleason 3+4 prostate cancer (PC) subgroup of similar biologic behaviour to Gleason 3+3.

Material And Method: An observational post-radical prostatectomy study was conducted of a cohort of 799 patients with localised low-risk (n=582, Gleason 6, PSA <10ng/ml and cT1c-2a) and favourable intermediate PC (n=217, Gleason 3+4, PSA ≤10 ng/ml and pT2abc). The Gleason 3+4 tumours were stratified by number (≤3 vs.
