conclusions bladder perforation and stones are rare examples of complications in v-p surgical procedures. controlling the effective length of the terminal v-p shunt and modifying it appropriately can effectively reduce these complications. case presentation we report on a 38-year-old male who had hydrocephalus and v-p shunt for 12 years. two years ago, he found himself with recurrent urinary tr...

PURPOSE The internal (smooth muscle) and the external (rhabdosphincter striated muscle) urethral sphincters have important roles in the genesis of urethral closure pressure. The U-shaped pelvic floor puborectalis muscle is important in the closure of anal and vaginal orifices in humans. We defined the contribution of the puborectalis to urethral pressure. MATERIALS AND METHODS A total of 11 f...

background and objective: nanoscopic life forms called nanobacteria or calcifying nanoparticles (cnp) are unconventional agents. these novel organisms are very small (0.1 to 0.5 microns) and possess unusual properties such as high resistance to heat and routine antimicrobial agents. nanobacteria are 100 times smaller than bacteria and protected by a shell of apatite, so they could be as candida...

Background: Iatrogenic urethral injury is a well-known risk of urinary catheter insertion. Associated morbidities include stricture formation, catheter associated infection, risk for instrumentation, and extended length of stay. Yet, insufficient attention is paid to its prevention. Objective: This study aimed to assess the effectiveness of a computerized...

Previous studies have suggested a relationship between bile duct stones and periampullary duodenal diverticula. The aim of the present study was to examine this association in more detail, including step-wise logistic regression to identify independent predictors for the presence of diverticula. Clinical, endoscopic and radiological data were analysed from 794 consecutive subjects with bile duc...

BACKGROUND Patients with symptomatic kidney stones are characterized by older age, male gender, white race, hypertension, obesity, metabolic syndrome and chronic kidney disease. Whether these characteristics differ in patients with asymptomatic kidney stones is unknown. METHODS All potential kidney donors who underwent protocol computed tomography angiograms/urograms (2000-08) at the Mayo Cli...

There is a possibility that unnecessary treatments and low-quality medical care, such as inappropriate indwelling urethral catheter use, are being provided to older Japanese individuals.The aim of this study was to investigate contextual effects relating to indwelling urethral catheters in older people with dementia and to clarify the effects of indwelling urethral catheter use on patients' mor...

BACKGROUND Urethral calculi are rare and usually encountered in males with urethral pathology. OBJECTIVE To present our experience managing urethral calculi in a resource limited centre and review the literature. METHODS We did a chart review of management of patients with urethral calculi between January and April 2009, at Federal Medical Centre (FMC) Azare, Nigeria. We also reviewed the l...
