Se Young Choi, Chang Gyo Yoon
We sought to describe the incidence rate of the urologic disease in the Korean military by reviewing diagnoses made in active duty soldiers from 2008 to 2013. A total of 72,248 first visits were generated in the Defense Medical Statistics Information System (DMSIS) with its gradually increasing trend over 6 years. A sharp increase of first visit was observed after implementation of the regular health check-up for all conscripted soldiers since 2013. Urolithiasis, prostatitis, epididymoorchitis, urethritis, and varicocele were prevalent...

BACKGROUND: Extracorporeal shock wave lithotripsy (ESWL) is an important tool for the management of urolithiasis. The effects of shockwaves on tissues are established. The aim of this meta-analysis is to evaluate the microscopic semen characteristics of young men before and after ESWL treatment for lower ureteral calculi. METHODS: Literature searches were performed following the Cochrane guidelines. We conducted a systematic review and meta-analysis that included six trials that investigated the effects of ESWL on semen parameters, including sperm concentration, motility, and hematospermia...

Animal models are useful in the study of many human diseases. Our current understanding of the biological, physiological, and biochemical aspects of hyperoxaluria and calcium oxalate urolithiasis has been greatly informed by studies using animals. Recently, limitations in the extrapolation to humans of research results derived from laboratory rodents have been identified. The use in biomedical research of a variety of organisms, including large animals, is increasingly encouraged. The purpose of this article is to review the use of pigs in biomedical and stone research, to provide a rationale for using pigs in metabolic stone research, and to describe our 8-year experience in developing a porcine platform for studying hyperoxaluria and calcium oxalate urolithiasis...

Urinary catheter use is prevalent in health care settings, and polymicrobial colonization by urease-positive organisms, such as Proteus mirabilis and Providencia stuartii, commonly occurs with long-term catheterization. We previously demonstrated that coinfection with P. mirabilis and P. stuartii increased overall urease activity in vitro and disease severity in a model of urinary tract infection (UTI). In this study, we expanded these findings to a murine model of catheter-associated UTI (CAUTI), delineated the contribution of enhanced urease activity to coinfection pathogenesis, and screened for enhanced urease activity with other common CAUTI pathogens...

Urolithiasis or urinary stone disease has been estimated to affect about 1 in 11 Americans. Patients with urinary stone disease commonly present to the emergency department for management of their acute pain. In addition to providing analgesia, administration of drug (medical expulsive therapy) is often prescribed to assist passage of the urinary stone. In this methodology paper, we describe the design of a prospective, multi-center, randomized, double-blind placebo controlled clinical trial of the alpha-adrenergic blocker, tamsulosin, to evaluate its effectiveness as medical expulsive therapy...

Xanthium strumarium has traditionally been used in the treatment of urolitiasis especially by the rural people in India, but its antiurolithiatic efficacy was not explored scientifically till now. Therefore, the present study was designed to validate the ethnic practice scientifically, and explore the possible antiurolithiatic effect to rationalize its medicinal use. Urolitiasis was induced in hyperoxaluric rat model by giving 0.75% ethylene glycol (EG) for 28days along with 1% ammonium chloride (AC) for first 14days...

Background: Flexible ureteroscopy (fURS) is one of the main treatment options for urolithiasis less than 2 cm. Although fURS has no relative contraindication, some anatomical factors may need to be considered, as not all patients are suitable for the regular lithotomy position (LP). We report the case of a patient with a right iliac vascular graft that after an fURS without intraoperative incidences developed a reperfusion syndrome of the right lower limb. Case Presentation: A 46-year-old male patient was referred for treatment and follow-up in the cystinuric clinic after being found to have a 3 cm pelvic stone with a Double-J catheter in place after two failed sessions of shockwave lithotripsy...

BACKGROUND: In contrast to adult patients, a relatively large number of open surgical procedures are still needed in the treatment of urolithiasis in children. Since almost all open surgical techniques may be reproduced by minimal access surgery (MAS), there is a rationale to apply the latter in the management of pediatric urolithiasis. Our study aimed to assess the feasibility and outcome of MAS in the treatment of pediatric urinary calculi. METHODS: The charts of patients with urolithiasis submitted to MAS between 1994 and 2007 were retrospectively reviewed...
