1/6. 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 = 1keywords = extraction (Clic here for more details about this article) |
2/6. Case report: the stone-basket nidus.A 55-year-old man presented with intermittent right-flank pain 6 months after ureteroscopic stone extraction with holmium laser lithotripsy. A distal-ureteral stone was removed that contained fragments of a stone basket. Diligent inspection of endourologic accessories is critical to ensuring no fragments are left in patients, especially when a laser has been used.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/6. Endoscopic extraction of eroded Marlex mesh in a Kock pouch.We report a case of recurrent calculi in a Kock pouch continent urinary diversion. An open operation was avoided by successfully excising the Marlex mesh and removing it with the associated calculi in an endoscopic fashion.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
4/6. Ambulatory treatment by extracorporeal shock wave lithotripsy for an urethral stone in a hypospadic boy.A 13-year-old hypospadic boy with a urethral stone was successfully treated with extracorporeal shock wave lithotripsy after various unsuccessful attempts at urological extraction. The easiness of ESWL application in this case and the quick elimination of the stone suggest that ESWL should be considered in the management of urethral calculi.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/6. Extracorporeal shock wave lithotripsy for the treatment of bulbous urethral stones.Extracorporeal shock wave lithotripsy was used to treat multiple, large, bulbous urethral calculi in a paraplegic man. Prior attempt at endoscopic extraction was unsuccessful owing to the size and location of the calculi. Two treatments of 3,000 shocks each resulted in fragmentation of the calculi- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/6. Urethral calculus extraction using a penile ring block anesthetic.Urethral calculi are rare and usually originate from the kidney or bladder. Classically, they are extracted endoscopically under anesthesia. We present two cases of impacted distal urethral calculi extracted using a penile ring block and forceps.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
