1/250. Canine calcium oxalate urolithiasis. Case-based applications of therapeutic principles.

    The case study presented here illustrates the diagnosis and management of calcium oxalate urolithiasis in a Bichon Frise, a breed at increased risk for this type of stone. If the Bichon Frise had persistent hypercalcemia, we would have evaluated serum concentrations of ionized calcium, parathyroid hormone, and vitamin d to identify an underlying cause. Because his urine was alkaline, additional potassium citrate was not provided. Likewise, as a fortified diet was fed to him, vitamin B6 therapy was not considered. This case study illustrates the benefits of radiographic evaluation immediately following surgery and during follow-up examinations. If we had postponed radiographs until the patient developed clinical signs, additional surgical procedures may have been required. ( info)

2/250. New aspects of urinary tuberculosis.

    In urinary tuberculosis, during recent years, there has been remarkable progress in treatment but some new aspects are reported, which raise problems in diagnosis and therapeutics. There is an increase of silent forms, forms with rapid destructive development, even under treatment, and forms masked by association with other diseases. The percentage of elderly patients has increased, as has the number of cases presenting with advanced lesions with little clinical manifestation. This calls for more careful searching, assessment and survey of any suspected case. ( info)

3/250. hypercalciuria and urolithiasis in a case of costello syndrome.

    costello syndrome is characterized by postnatal growth deficiency, mental retardation, curly hair, coarse characteristic face, and loose skin of hands and feet. patients with this syndrome have a high incidence of cardiac involvement, including arrhythmia, atrial septal defect, and hypertrophic cardiomyopathy. We report a 16-year-old adolescent female with costello syndrome who presents with hypercalciuria and urolithiasis. ( info)

4/250. Percutaneous chemolysis--an important tool in the treatment of urolithiasis.

    Persistent residual calculi after therapy, i.e. extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolitholapaxy (PNL), as well as pyelo- and nephrolithotomy are big problems in the treatment of urolithiasis. Furthermore, the therapy of stones is problematic in patients with inadequate drainage, impaired kidney function, or with high risks against anaesthetics. Between 1991 and 1997 percutaneous antegrade chemolysis was carried out in eleven patients. In nine of them complete dissolution of stones was achieved. In two further cases, in which calcium oxalate was the main component of the stones, chemolysis was unsuccessful. Through our own cases and under consideration of the literature, we will show that percutaneous chemolysis in these cases is useful and effective in the treatment of urolithiasis. ( info)

5/250. Delayed transection of urethra by mersilene tape.

    This report is of a patient with complete urethral transection after undergoing a mersilene sling urethral suspension. This unusual complication eventually presented as anterior urethral pseudodiverticulum containing the mersilene tape with a secondary calculus. ( info)

6/250. An unusual cause of bladder rupture in a paraplegic.

    Over distention of the bladder or a bladder substitute may lead to rupture. The chances of rapture are more in a previously scarred bladder, particularly in a patient with poor sense of bladder fullness such as paraplegic. ( info)

7/250. Recurrent suture urolithiasis 29 years after open pyelolithotomy.

    A case of a foreign body-induced renal stone in which the patient was treated successfully with a ureterorenoscopic approach is presented. ( info)

8/250. Giant calculus in a female urethral diverticulum.

    Urethral diverticula with calculi are rare. This 5x6 cm calculus presented in a patient with recurrent urinary tract infections. Local excision was effective. ( info)

9/250. drug-seeking behavior in urolithiasis in the noncontrast computed tomography era: 2 cases.

    Symptomatic urolithiasis is usually treated with narcotic pain management. This leads to the potential for use of its symptoms for personal gain. Historically, the typical presentation of a narcotic-seeking "stone patient" was a history of radiolucent stones and an intravenous contrast allergy. With the increased use of non-contrast-enhanced computed tomography to evaluate patients suspected of having acute urolithiasis, we have seen a change in the strategy of narcotic-seeking patients. We report 2 patients with pelvic calcifications on non-contrast-enhanced computed tomography feigning symptoms of urolithiasis to receive narcotic drugs. ( info)

10/250. Bilateral percutaneous nephrolithotomy for multiple cystine stones in an infant presenting with anuria.

    We report the first case of simultaneous, bilateral percutaneous management of multiple urinary cystine stones in a 7.6-kg, 9-month-old infant who presented with anuria. A stone-free state was successfully achieved. ( info)
