13. Retroperitoneoscopic approach for urolithiasis treatment
ABSTRACT Objective To show the main indications of retroperitoneoscopy (RP) for the treatment of urolithiasis. The use of RP approach has been limited, being narrow working space the major issue to overcome (1), especially in non-expert hands. However, RP has the added advantages of no peritoneal contamination, a quick recovery of bowel function (2) and th

14. Association between calcitonin receptor gene polymorphisms and calcium stone urolithiasis: A meta-analysis
ABSTRACT Purpose It has been reported that calcitonin receptor (CALCR) gene polymorphisms might be associated with calcium stone urolithiasis. Owing to mixed and inconclusive results, we conducted a meta-analysis to summarize and clarify this association. Materials and Methods A systematic search of studies on the association between CALCR gene polymorphis

17. Effect of vitamin D supplementation on 24-hour urine calcium in patients with calcium Urolithiasis and vitamin D deficiency
ABSTRACT Purpose: Hypercalciuria is one of the risk factors for calcium kidney stone formation (the most common type of urinary stones). Although vitamin D deficiency is prevalent among urolithiasis patients, the effect of vitamin D supplementation on urine calcium in these patients is still unclear. Materials and Methods: In this retrospective study, medi

18. Predictors of surgical complications of nephrectomy for urolithiasis
ABSTRACT Objectives: Nephrectomy due to stone disease may be a challenging procedure owing to the presence of significant inflammation and infection, involving high complication rate. The objective of our study was to identify predictors for complications of nephrectomy for urolithiasis. Patients and Methods: A retrospective review of 149 consecutive patie

19. Ureteral access sheaths: a comprehensive comparison of physical and mechanical properties
ABSTRACT Introduction: Ureteral access sheaths (UAS) facilitate flexible ureteroscopy in the treat- ment of urolithiasis. The physical properties of UAS vary by manufacturer and model. We compared three new UAS: Glideway (GW, Terumo, 11/13Fr, 12/14Fr), Pathway (PW, Terumo 12/14F) and Navigator HD (NHD, Boston Scientific, 11/13Fr, 12/14Fr) in the domains of

20. Quality of life and urolithiasis: the patient - reported outcomes measurement information system (PROMIS)
ABSTRACT Background: With a high rate of recurrence, urolithiasis is a chronic disease that impacts quality of life. The Patient Reported Outcomes Measurement Information System is an NIH validated questionnaire to assess patient quality of life. We evaluated the impact of urolithiasis on quality of life using the NIH-sponsored PROMIS-43 questionnaire. Mat

23. Are patients with lichen planus really prone to urolithiasis? Lichen planus and urolithiasis
ABSTRACT Purpose to investigate whether patients with lichen planus (LP) are really prone to urolithiasis or not. Patients and Methods We performed a prospective analysis of 40 patients diagnosed with lichen planus (LP) (group I), and 40 volunteers did not have LP before (group II). Participants were all checked for urolithiasis by radiological investiga

24. Dipstick Spot urine pH does not accurately represent 24 hour urine PH measured by an electrode
ABSTRACT Objectives To determine whether spot urine pH measured by dipstick is an accurate representation of 24 hours urine pH measured by an electrode. Materials and Methods We retrospectively reviewed urine pH results of patients who presented to the urology stone clinic. For each patient we recorded the most recent pH result measured by dipstick from
