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...

melamine is a new risk of urinary stones. gansu province is a heavily affected area and has large population and underdeveloped economy. we hypothesized that number of family members and family income may play significant roles in the formation of urinary stones. a case-control study was performed among 190 infants. results showed that the case group had less numbers of family members than the ...

The purpose of this study was to assess the total phenol content and invitro antiurolithiatic activity Hibiscus cannabinus extract various fractions. Kidney stones are one most painful prevalent urinary tract disorders. Drug treatment Extracorporeal Shock Wave Lithotripsy (ESWL) used treat kidney stones. Instead dissolving stone, these treatments may cause acute renal damage an increase in ston...

The lifetime incidence of kidney stones is approximately 13 percent for men and 7 percent for women.1,2 Reports conflict regarding whether incidence is rising overall but consistently report rising incidence in women and a falling male-to-female ratio.3-5 Although stones may be asymptomatic,6 potential consequences include abdominal and flank pain, nausea and vomiting, urinary tract obstruction...

Penile urethral stones are a rare occurrence resulting from a number of causes including migration of stones within the urinary tract, urethral strictures, meatal stenosis, and obstructing tumours such as adenomatous metaplasia of the uroepithelium, hypospadias, urethral diverticulum, and very rarely primary fossa navicularis calculi. We report the case of a 54-year-old male presenting with pen...

Xanthine dehydrogenase catalyzes the oxidation of hypoxanthine to xanthine and xanthine to uric acid in the final two steps of the purine degradation process. Xanthine oxidase deficiency is an uncommon cause of pediatric urinary stone formation, and classical xanthinuria. A ten-month-old boy presented with a seven-month history of nausea, vomiting, discomfort during urination, gross hematuria a...

Cystinuria is an inherited metabolic disorder progressing with recurrent kidney stones due to impaired reabsorption of dibasic amino acids and arises from mutations in the SLC3A1 SLC7A9 on chromosome 2. Here, we present case a 1-year 10-month-old male child episodes urinary tract infections. On evaluation, duplex kidneys large bladder calculus were found which was surgically managed. Stone anal...

Multiple techniques exist to remove uroliths from each section of the urinary tract. Minimally invasive methods for removing lower urinary tract stones include voiding urohydropropulsion, retrograde urohydropropulsion followed by dissolution or removal, catheter retrieval, cystoscopic removal, and cystoscopy-assisted laser lithotripsy and surgery. Laparoscopic cystotomy is less invasive than su...

PURPOSE Urinary stasis is a risk factor for recurrent urinary tract infection (UTI). Homozygous mutant Megabladder (Mgb-/-) mice exhibit incomplete bladder emptying as a consequence of congenital detrusor aplasia. We hypothesize that this predisposes Mgb-/- mice to spontaneous and experimental UTI. METHODS Mgb-/-, Mgb+/-, and wild-type female mice underwent serial ultrasound and urine culture...

Most kidney stones are composed primarily of calcium oxalate. Oxalobacter formigenes is a Gram-negative, anaerobic bacterium that metabolizes oxalate in the intestinal tract and is present in a large proportion of the normal adult population. It was hypothesized that the absence of O. formigenes could lead to increased colonic absorption of oxalate, and the subsequent increase in urinary oxalat...
