Introduction: Bladder voiding diaries are an important part of evaluating and managing lower urinary tract symptoms but are subject to poor data quality and diary completion rates. Mobile health technology is increasingly prevalent and can help overcome the problems of traditional paper and electronic diaries.
Methods: We identified proof of concept design principles based on a literature review and needs assessment.
Purpose: Ureteroscopy is central to the surgical management of ureteral stones. Fluoroscopy is conventionally used for intraoperative guidance, although there is growing effort to decrease the exposure of patients and staff to ionizing radiation. We developed a radiation-free approach to ureteroscopy using ultrasound guidance to manage ureteral stones.

Methods: Medical records of patients who underwent holmium laser ablation of the prostate between 2007 and 2012 by a single surgeon were retrospectively reviewed. Patients with American Society of Anesthesiologists category ≥3 ("severe systemic disease") were included.
Unlabelled: Abstract Purpose: We examined the stone composition, 24-hour urinary risk factors, and insurance status in patients evaluated in two regional stone clinics to further investigate the relationship between the socioeconomic status and kidney stone formation.
Materials And Methods: We performed a retrospective review of stone formers who completed a 24-hour urinalysis as part of a metabolic evaluation for nephrolithiasis. Insurance status was determined by billing records and those with state-assisted insurance (SAI) were compared to patients with private insurance (PI).
Objective: To examine the effect of resident involvement on laser prostate surgery outcomes within a urology group in a private practice setting.
Materials And Methods: Patients with ≥ 6 months of follow-up data who had undergone holmium laser ablation of the prostate by a single surgeon (R.L.
We report a percutaneous transcloacal approach for removal of a ureteral stent in a 15-year-old girl with a cloacal anomaly, spinal dysraphism, and complex pelvic anatomy, including a bicornuate uterus, reconstructed hindgut neobladder, and duplicated left pelvic kidney. The patient had undergone 3 previous unsuccessful attempts at stent removal, 2 endoscopic attempts by way of her neobladder, and 1 percutaneous transcloacal attempt before successful removal.

Methods: A retrospective review of patients evaluated in 2 metabolic stone clinics was performed. Recurrent stone formation was defined as patients with a history of more than 1 stone episode and first-time stone-formers were those with a history of a single-stone episode.
Objective: To examine the relationship between urine magnesium and hyperoxaluria in a cohort of patients with recurrent stone formation.
Methods: A total of 311 patients with nephrolithaisis were evaluated. The patients were divided into quintiles of urine magnesium excretion, an accepted surrogate of dietary magnesium intake.
Objective: To examine the relationship between the poverty and education levels and 24-hour urine composition in patients with nephrolithiasis because little is known about the relationship between socioeconomic status and kidney stone risk.
Methods: A retrospective review was performed of patients evaluated at 2 metabolic stone clinics. The poverty level (ie, percentage of those living below the poverty level) and education level (ie, percentage of those with a high school education or greater) for each postal code were determined from the U.
Objective: To examine the relationship between GFR and 24-hour urine composition in patients with nephrolithiasis to understand how renal function may affect stone risk. Alterations in glomerular filtration rate (GFR) are associated with a number of physiological changes.
Methods: A retrospective, institutional review board-approved review of patients from 2 metabolic stone clinics was performed.
Unlabelled: Study Type--Prognosis (cohort series) Level of Evidence 2b. What's known on the subject? and What does the study add? Epidemiologic studies have shown that warmer climates are associated with increased incidence of nephrolithiasis. Many hypothesize that this is due to dehydration and lower urine volumes.

Materials And Methods: Consecutive women (121) referred for evaluation of lower urinary tract symptoms to a specialized urology clinic were given validated questionnaires including the Urogenital Distress Inventory-6 and Incontinence Impact Questionnaire-7. These data were then analyzed according to psychiatric comorbidities, history of sexual trauma, age, race and obstetric history.
Interstitial cells of Cajal (ICCs) have been identified as pacemaker cells in the upper urinary tract and urethra, but the role of ICCs in the bladder remains to be determined. We tested the hypotheses that ICCs express cyclooxygenase (COX), and that COX products (prostaglandins), are the cause of spontaneous rhythmic contraction (SRC) of isolated strips of rabbit bladder free of urothelium. SRC was abolished by 10 microM indomethacin and ibuprofen (non-selective COX inhibitors).
