1/5. Urethral stones: US for identification in boys with hematuria and dysuria.There are multiple causes for hematuria in infants and children. When hematuria is accompanied by dysuria, however, one should focus attention on the lower urinary tract. Although ultrasound (US) is a well-established method for assessing the kidneys and bladder, little attention has been focused on its use for evaluating urethral abnormalities, since voiding cystourethrography or retrograde urethrography usually is used. In the cases of two young boys, sonography aided in the identification of clinically unsuspected urethral stones. US evaluation of the urethra is now included as an integral part of urinary tract sonography in male patients with hematuria accompanied by dysuria.- - - - - - - - - - ranking = 1keywords = dysuria (Clic here for more details about this article) |
2/5. The tinkle tale.The clinical features of urinary calculi are well documented. Several textbooks state the features of passage of a stone per urethra including severe dysuria, straining and strangury. We report on three patients in whom attention was drawn to the passage of a stone by the sound made as the stone hit the bedpan during urination.- - - - - - - - - - ranking = 0.16666666666667keywords = dysuria (Clic here for more details about this article) |
3/5. urolithiasis associated with topiramate.OBJECTIVE: Topiramate is a sulfamate-substituted monosaccharide anticonvulsant used as adjunctive therapy for intractable refractory seizures. It is report a case of topiramate-induced urolithiasis. CASE REPORT: A 35-year-old man presented with acute, right-sided, colicky flank pain. He denied hematuria or dysuria. He was in use of phenytoin, risperidone, phenobarbital, and topiramate. The total daily dose of topiramate was 375 mg. A CT scan showed a 7 x 1 mm curvilinear density at the right ureterovesical junction with proximal hydrouretronephrosis. He was managed with rigid ureteroscopic stone extraction and the calculus metabolic analysis revealed the stone was composed of carbonate apatite (70%), calcium oxalate dihydrate (20%), and calcium oxalate monohydrate (10%). COMMENTS: The present case typifies many features of topiramate-induced urolithiasis. Those who care for patients with urinary stone disease should be aware of this association.- - - - - - - - - - ranking = 0.16666666666667keywords = dysuria (Clic here for more details about this article) |
4/5. Irritability and dysuria in infants with idiopathic hypercalciuria.Idiopathic hypercalciuria (IH) is being diagnosed with increasing frequency in the pediatric population and occurs in approximately 2.9-6.2% of normal children. The majority of children with IH are asymptomatic; however, the most common clinical presentation is that of isolated hematuria (gross or microscopic). The prevalence, presentation and clinical course of IH is less well established in infants. We have recently seen two young infants with IH who had dysuria on presentation. Their hypercalciuria was difficult to manage and required frequent manipulations of drug therapy and diet restrictions. These cases emphasize the importance of evaluating infants with dysuria and irritability for IH, even in the absence of hematuria. Further studies are needed to establish the prevalence and classical presentation of IH in this population, and to determine the necessary duration of therapy.- - - - - - - - - - ranking = 1keywords = dysuria (Clic here for more details about this article) |
5/5. sulfadiazine-induced multiple urolithiasis and acute renal failure in a patient with AIDS and toxoplasma encephalitis.OBJECTIVE: To report a patient with sulfadiazine-induced urolithiasis and acute renal failure. CASE SUMMARY: A patient with AIDS who was being treated with pyrimethamine and sulfadiazine for toxoplasma encephalitis developed lumbar pain, dysuria, urinary frequency, and hematuria. Acute renal failure was found and numerous crystals of sulfadiazine were seen in the urine. Multiple calculi of up to 2 cm in diameter in both kidneys were noted on ultrasound. The patient was treated with intravenous fluids and alkalinization of the urine with rapid improvement. An intravenous urographic study performed 2 days later showed no evidence of calculi and renal function was normal. DISCUSSION: patients with AIDS and toxoplasma encephalitis may have several predisposing conditions that can lead to the development of sulfadiazine-induced crystalluria, including poor fluid intake, fever, diarrhea, and hypoalbuminemia, in addition to the high doses of the drug required and the prolonged period of treatment. CONCLUSIONS: This potentially serious complication can be managed easily with conservative treatment. Clinicians should be aware of this complication as it is expected to occur more frequently as more patients are treated with sulfonamides and patients with AIDS experience longer survival rates.- - - - - - - - - - ranking = 0.16666666666667keywords = dysuria (Clic here for more details about this article) |
