Male F344 rats were given a diet supplemented with uracil at concentrations of 1 or 3% for 15 or 30 wk. In the group given 3% uracil, numerous calculi of uracil were observed in the urinary tract with marked hyperplasia and papillomas of the urinary bladder mucosa in Wk 15 and 30. In Wk 30, dysplasia of the ureteral mucosa and one transitional cell carcinoma of the bladder were also found. Neit...

The clinical significance of Proteus penneri, a newly described species, is unknown. A case report is presented, which is to the best of our knowledge the first description of this organism causing a urinary tract infection and bladder calculi.

Frequency of urinary tract infection was determined in 82 patients with urolithiasis and in 40 patients with an indwelling Catheter. Significantly high proportion of adult patients with renal and vesical calculi were infected while children with bladder stones had high proportion of sterile urine. Indwelling catheter was associated with a high rate of urinary infection (JPMA 31:254,1981).

We report an uncommon case of a-48-year-old female presenting with calculi over suture in bladder following prior abdominal hysterectomy. The stone was fragmented and removed via transurethral cystolitholapaxy using pneumatic energy followed by cystoscopic removal of the suture. Bladder stones are rarely found in females (2%) and their occurrence should be evaluated in detail. Foreign bodies in...

conclusions when evaluating flank pain in patients, it is important to remember that cbc parameters may support urinary stone disease, and considering cbc results may be useful in the diagnosis of urinary stone disease. patients and methods this study was a retrospective observational study of 3,099 patients who were admitted to the urology outpatient clinic or diagnosed with urinary stone dise...

background urinary stone incidence in pregnancy has been reported in a wide range, from 1 in 200 to 1 in 2000 cases. objectives the aim of this study was to investigate the efficacy and safety of ureteroscopic treatment and its results and complications for pregnant women with urinary stones. patients and methods from 2003 till 2011, 113 pregnant patients with symptomatic urolithiasis were admi...

botulinum toxin (bt) is a potent presynaptic neuromuscular blocking agent which induces selective, reversible muscle weakness for months when injected intramuscularly.during recent years bt has revolutionized the treatment of previously intractable symptoms of detrusor overactivity. based on a systematic search of the pubmed database,a review of the current literature on the use of onabotulinum...

The great difficulty of distinguishing nephro-lithiasis from many other pathological conditions of the genito-urinary tract ?especially early tubercular disease of the kidney?is well known; but, except in the case reported below, the Rontgen rays have not yet proved of much practical value in the diagnosis of renal calculus.1 It can be, however, only a matter of time; and there is little doubt ...

Some simple mathematical formulae to calculate the volumes of proximal pyeloureteral reflexive systems are presented, and the results are compared to bladder capacity values. Using the results of the calculi, the author discusses possible implications of severe urinary sequestration in the pyeloureteral systems. Using geometrical and topological approximations we calculate the volumes of ureter...
