1/102. Unusual case of Munchausen's syndrome: factitious vesical lithiasis.We report an uncommon case of a 38-year-old woman who admitted for bladder lithiasis undergoing repeated surgical management and being apparently recurrent. The intravenous pyelography and retrograde urethrocystography clear the urinary tract. Biologic evaluation eliminates any metabolic or endocrine cause. The confirmation of a factitious origin is given by fluorescence X analysis of the extracted stones which conclude to calcium carbonate structure and psychiatric care. The self-intromission of these calculi into the bladder is due to the personality disorder being in the frame of Munchausen's syndrome. Two years later, no recurrence is noted and an excellent psychiatric care is achieved.- - - - - - - - - - ranking = 1keywords = stone (Clic here for more details about this article) |
2/102. An unusual presentation of a foreign body in the urinary bladder: A migrant intrauterine device.A 35-year-old woman, who had had an intrauterine device inserted 7 years earlier, presented with dysuria, pollakiuria, suprapubic pain and urethral irritation. The intrauterine device was found in the bladder with stone formation and was removed by endoscopy.- - - - - - - - - - ranking = 1keywords = stone (Clic here for more details about this article) |
3/102. Percutaneous vesicolithotomy: an alternative to open bladder surgery in patients with an impassable or surgically ablated urethra.PURPOSE: Although vesical calculi are routinely treated transurethrally, open vesicolithotomy is generally performed in patients with an impassable or surgically ablated urethra. We describe a technique of percutaneous vesicolithotomy which we used in patients who had undergone urethral ablation and concomitant continent diversion by appendicovesicostomy. MATERIALS AND methods: Bladder stones were detected in 3 patients with neurogenic bladder who had undergone continent urinary diversion with bladder neck closure and appendicovesicostomy. To treat the stones access to the bladder was achieved percutaneously and the tract was enlarged using a balloon dilator. An Amplatz sheath was slipped over the inflated balloon and after the dilator was removed the sheath provided a working channel through which stones were fragmented and removed using a nephroscope. RESULTS: Each patient was rendered stone-free and discharged home the same day as the procedure. CONCLUSIONS: Percutaneous vesicolithotomy provides an alternative approach for bladder stone removal in patients with an impassable urethra with decreased morbidity compared to open procedures.- - - - - - - - - - ranking = 5keywords = stone (Clic here for more details about this article) |
4/102. xanthine stone in the urinary bladder of a male child.urinary tract calculi composed primarily of xanthine are rate both in adults and children. We describe the clinical presentation and management of a 3.5-year-old boy with hereditary xanthinuria (an autosomal recessive disorder of purine metabolism) and primary bladder calculus formed from xanthine. To our knowledge this case demonstrates a previously undescribed form of xanthinuria in childhood. xanthine stones, although rare, should be considered in the diagnosis of urolithiasis.- - - - - - - - - - ranking = 18.374695470165keywords = calculus, stone (Clic here for more details about this article) |
5/102. Intravesical migration of AMS 800 artificial urinary sphincter and stone formation in a patient who underwent radical prostatectomy.A patient who underwent placement of AMS 800 urinary sphincter for incontinence after salvage prostatectomy after radiation therapy failure, experienced urethral erosion of the cuff after 54 months. He was treated with cuff removal and prosthesis deactivation. Thirteen months later, a large bladder stone was removed transvesically, and it contained the reservoir. The remaining sphincter components were also removed. patients with previous radiotherapy are particularly at risk for sphincter erosion, but intravesical displacement of the reservoir is a very uncommon complication.- - - - - - - - - - ranking = 5keywords = stone (Clic here for more details about this article) |
6/102. Giant neobladder calculus.An unusual case of a calculus in the ileal neobladder is presented. The size of the stone is exceptional in the urologic literature (940 g). Neocystolithotomy was performed, with full patient recovery.- - - - - - - - - - ranking = 67.873477350824keywords = calculus, stone (Clic here for more details about this article) |
7/102. Calculus-producing and cytomegalovirus-infected nephrogenic adenoma of the bladder in a prepubertal renal transplant recipient.A 14-year-old prepubertal boy, a renal transplant recipient, was treated for a nephrogenic adenoma. His case is unique in that he is the second youngest renal transplant recipient diagnosed with a nephrogenic adenoma. In addition, the lesion was calculus producing, which has not been previously described, and contained cytomegalovirus inclusions, which has been described only once previously in association with a nephrogenic adenoma in a transplant patient.- - - - - - - - - - ranking = 13.374695470165keywords = calculus (Clic here for more details about this article) |
8/102. Bladder stones around a migrated and missed intrauterine contraceptive device.Bladder stones occasionally develop because of foreign bodies in the bladder. Bladder stones in a 30-year-old woman were found to have formed around an intrauterine contraceptive device that had gone missing many years previously and had migrated into the bladder. Plain abdominal radiograms should be a part of the evaluation in patients with a history of an unretrieved intrauterine contraceptive device.- - - - - - - - - - ranking = 6keywords = stone (Clic here for more details about this article) |
9/102. female pseudohermaphroditism associated with cloacal anomalies: faulty differentiation in the caudal developmental field.A 1(1/2)-year-old girl with a urogenital sinus defect associated with an enlarged phalluslike clitoris is described. The child had an anteriorly located anus, a single kidney with grade III vesicoureteric reflux, a 3.5-cm-long common urethrovaginal channel, a large vesical calculus, and a hamartoma in the pubic region. After a preliminary colostomy, definitive surgery consisted of urethral reconstruction, vaginal reconstruction using a colonic graft, and posterior relocation of the anus. The discussion centers on a review of the previously reported cases of female pseudohermaphroditism associated with cloacal or urogenital sinus defects (FPHCD). The likely embryogenesis of this condition is discussed, and the similarity of the features with those seen in some patients with complete penoscrotal transposition (CPST) is highlighted.- - - - - - - - - - ranking = 13.374695470165keywords = calculus (Clic here for more details about this article) |
10/102. Development of a large bladder calculus on sutures used for pubic bone closure following extrophy repair.bladder exstrophy is a rare congenital condition that occurs in 1 to 30,000 live births. Primary bladder closure is usually performed in the first days of life in conjunction with an iliac osteotomy in order to achieve a more secure bladder closure. We report a case of a large bladder stone with secondary right-sided hydronephrosis in a 3-year-old child who underwent exstrophy repair at the age of 7 months. During the exstrophy repair a no. 1 braided, polyester, non-absorbable suture was used to close the pubic bones and served as a nidus for intravesical stone formation. This case substantiates the lithogenic nature of non-absorbable sutures in contact with urine as well as the need for close post-operative follow-up in these patients.- - - - - - - - - - ranking = 55.498781880659keywords = calculus, stone (Clic here for more details about this article) |
