1/345. Upper urinary tract obstruction: pressure/flow studies in children.34 upper urinary tract pressure/flow studies were carried out in 24 children. Obstruction was reliably diagnosed in 8 studies, and excluded in 21. This technique may provide information of clinical value in the patient with upper urinary tract dilatation.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
2/345. Urinary undiversion for pelvic actinomycosis: a long-term follow up.BACKGROUND: A 43-year-old woman who had been using intrauterine contraceptive devices for the past 10 years underwent an emergency operation for bowel and urinary obstruction. methods/RESULTS: Frozen section analysis showed undifferentiated adenocarcinoma. Incomplete tumorectomy, ileal resection, partial cystectomy, colostomy and bilateral ureterocutaneostomy were palliatively performed. Postoperatively, periodic acid-Schiff and Grocott-Gomori methenamine tests revealed actinomyces and the final diagnosis was pelvic actinomycosis. Treatment with penicillin g administered intravenously relieved her symptoms and the lesion was dramatically improved. The patient underwent colostomy closure and urinary undiversion. CONCLUSIONS: Five years after urinary undiversion, the patient's renal function has been maintained and she can void without incontinence and dysuria.- - - - - - - - - - ranking = 0.5keywords = urinary (Clic here for more details about this article) |
3/345. Management of ureteric obstruction in the solitary kidney by a segmental suspended ureteric prosthesis.Ureteric obstruction of a single kidney, secondary to an aorto-iliac bypass graft, was treated with a suspended segmentary ureteric prosthesis. No urinary stasis was observed during 1 year and the urodynamic implication are discussed.- - - - - - - - - - ranking = 0.16666666666667keywords = urinary (Clic here for more details about this article) |
4/345. Acute renal failure due to obstruction in burkitt lymphoma.Acute renal failure in burkitt lymphoma is commonly the result of tumor lysis syndrome. We present a 15-year-old boy who developed hypertension, seizures, and acute renal failure due to extrinsic compression of the bladder and ureters by a large retrovesical burkitt lymphoma. The causes of acute renal failure in burkitt lymphoma and the incidence of acute urinary obstruction in this disease are reviewed.- - - - - - - - - - ranking = 0.16666666666667keywords = urinary (Clic here for more details about this article) |
5/345. Ureteric obstruction due to kinking of the reservoir inlet in a continent urinary reservoir.We report a case of symptomatic intermittent upper tract obstruction in a continent urinary reservoir. The ureters were of great intraperitoneal length and were positioned in front of the mesenterium, resulting in a mobile reservoir. Only the retroperitoneal part of the ureters was dilated due to kinking in the peritoneal passage. After the ureters were shortened and reanastomosed retroperitoneally, the repeated episodes of abdominal pain and discomfort disappeared..- - - - - - - - - - ranking = 0.83333333333333keywords = urinary (Clic here for more details about this article) |
6/345. Buccal mucosal grafts in the treatment of ureteric lesions.OBJECTIVE: To devise a procedure capable of curing complicated ureteric strictures and replacing segments of lost ureter, without the long-term infective complications of bowel interposition or the surgical magnitude of autotransplantation. patients AND methods: Four patients with complicated strictures and one with segmental ureteric loss were treated by buccal mucosal patch grafts and an omental wrap. One patient with segmental ureteric loss was treated by interposition of a tubularized buccal mucosal graft. RESULTS: Ureteric patency was established and maintained in all patients, there were no complications and urine was sterile in all patients at follow-up. CONCLUSION: In a few patients, buccal mucosal patch graft repair has proved capable of maintaining patency and good urinary drainage in patients with complicated ureteric strictures. Segmental ureteric loss has been replaced in one patient by a patch graft and in another by tubularized graft interposition.- - - - - - - - - - ranking = 0.16666666666667keywords = urinary (Clic here for more details about this article) |
7/345. holmium: YAG laser endoureterotomy in the treatment of ureteroenteric strictures following orthotopic urinary diversion.The management of ureteroenteric strictures in patients who have undergone urinary diversion can be challenging. In those patients with an orthotopic neobladder, anastomotic ureteral strictures can be treated endoscopically using a retrograde or antegrade approach. The availability of small (7.5F) flexible ureteroscopes, as well as the use of the holmium laser has facilitated the ability to precisely incise the stricture under direct endoscopic visualization (endoureterotomy). We describe our technique for laser endoureterotomy in patients with ureteroenteric strictures following orthotopic urinary diversion.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
8/345. Neurofibromatous ureteral obstruction relieved by sigmoid conduit cystoplasty.Neurofibromatosis is a neural disease of hereditary nature affecting both sexes of all races. Visceral and central nervous system involvement can cause serious interference with normal function of affected structures. Under these circumstances, lifelong observation and individualized treatment of the patient are essential to proper management. This report is an account of nearly 2 decades of conservative management of neurofibromatosis of the pelvis in a young woman. Progressive, bilateral ureteral obstruction developed but normal function of the urinary tract has been maintained for the last 10 years with a sigmoid conduit cystoplasty. It is anticipated that continued progression of the disease will require cutaneous transfer of the sigmoid conduit. Also, a colostomy might become necessary because of recent evidence of rectal obstruction noted on computed tomography.- - - - - - - - - - ranking = 0.16666666666667keywords = urinary (Clic here for more details about this article) |
9/345. Permanent stenting in the treatment of ureteral strictures.Permanent metallic stents have found wide application for use in the vascular and biliary systems and currently devices are also available for use in the urinary tract. Permanent stenting of the ureter has proven to be an useful option in the management of obstruction caused by external compression due to malignancy whereas the efficacy of permanent stenting in the treatment of benign ureteral strictures is still controversial. We treated three patients with benign ureteral strictures by implantation of a self-expanding endoluminal stent that resulted in ureteral patency persisting up to 24 months.- - - - - - - - - - ranking = 0.16666666666667keywords = urinary (Clic here for more details about this article) |
10/345. Terminal deletion of chromosome 10q at band 26.1: follow-up in an adolescent male with high-output renal failure from congenital obstructive uropathy.We report on the clinical findings in an adolescent male with a de novo terminal deletion of chromosome 10 del(10)(q26.1). This young man is one of the oldest known patients reported with this condition. His condition is compared with that of 11 reported cases of de novo terminal deletion of 10q at band 26. Individuals with chromosome 10q26 deletion have some findings and medical complications in common. Our patient has chronic renal failure due to urinary tract obstruction from posterior urethral valves. Similar anomalies have been reported in cases of 10q26 deletion, suggesting a careful renal/urinary tract evaluation should be completed in individuals with this condition.- - - - - - - - - - ranking = 0.33333333333333keywords = urinary (Clic here for more details about this article) |
