Comparing Thulium Fiber Versus High-Power Holmium Laser Lithotripsy Combined with the Flexible and Navigable Suction Access Sheath in Flexible Ureteroscopy for Kidney Stone Disease: A Propensity Score Matched Analysis by the Global FANS Collaborative Group.

We aim to evaluate stone-free rate (SFR) and complications after flexible ureteroscopy (F-URS) for kidney stones, using a flexible and navigable suction ureteral access sheath (FANS), comparing thulium fiber laser (TFL) and high-power holmium:yttrium-aluminum-garnet laser (HPHL). Data from adults who underwent F-URS in 15 centers were prospectively analyzed (August 2023-January 2024). Exclusion criteria were ureteral stones, concomitant bilateral procedures, and renal abnormalities.

Introduction: Decision-making for complex pediatric urinary system stone disease is still a challenge for pediatric urologists. The interest in supine percutaneous nephrolithotomy (PCNL) is increasing among centers to achieve high surgical success rates with less morbidity. Despite advanced retrograde intrarenal surgery armamentarium, percutaneous approaches remain the first-line surgical treatment modality for >2 cm and complex renal stones.

Role of urine glycosaminoglycan levels in the diagnosis and follow-up in men with lower urinary tract symptoms.

Objective: The aim of this study was to investigate whether urinary glycosaminoglycans (GAG) levels reflect clinical status in men with lower urinary tract symptoms and if they could be used as a marker in management of overactive bladder (OAB).

Methods: A total of 34 patients were recruited who were admitted with LUTS and diagnosed as having clinically bladder outlet obstruction (BOO) due to prostate enlargement. These newly diagnosed, never treated patients underwent routine investigation, consisting of history, physical examination, PSA, ultrasound, uroflowmetry, assessment of symptoms scored by both International Prostate Symptom Score (IPSS) and Marmara- Overactive Bladder Questionnaire (M-OBQ).

Comparison of maximum voided volume and maximum bladder capacity in voiding diary, uroflowmetry and cystometrography in children with non-neurogenic lower urinary tract dysfunction.

Background: Maximum voided volumes (MVV) and maximum bladder capacities (MBC) are important parameters in the evaluation of lower urinary tract functions in children. However, consistency of MVV and MBC measurements between voiding diary (VD), uroflowmetry (UF) and cystometrography (CMG) in children with non-neurogenic lower urinary tract dysfunction (LUTD) has not been addressed specifically.

Objective: We aimed to compare the MVV in VD and UF and MBC in CMG in children with non-neurogenic LUT dysfunction and investigate for possible factors for discrepancies.
