11/353. Laparoscopic excision of endocervicosis of the urinary bladder.Endocervicosis is a benign lesion in which endocervical mucosa develops in anatomic locations distant from the endocervical canal. Two cases of infiltrating endocervicosis of the urinary bladder were managed by laparoscopic partial cystectomy. This avoided the morbidity of laparotomy and provided improved visualization of the extent of bladder resection required to remove the lesion completely.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
12/353. prenatal diagnosis of cystic bladder distension secondary to obstructive uropathy.We report the perinatal findings of a huge midline posterior cystic bladder distension secondary to lower urinary tract obstruction and prune-belly syndrome in a male fetus. A 40-year-old woman, gravida 3, para 0, was referred at 21 gestation weeks with sonographic findings of anhydramnios and a fetus with a 9.5 x 6.0 cm intra-abdominal cystic mass containing two chambers. The in utero ultrasound-guided fetal bladder drainage using a single needle aspiration and the ultrasound follow-ups of fetal bladder filling provided a diagnostic aid. This method helped to show the position of the bladder and the cystic bladder mass as well as the status of communication in response to decompression or filling of the fetal bladder. cytogenetic analysis revealed a 46,XY karyotype. autopsy showed agenesis of the posterior urethra, prominent megacystis, a cystically distended mass arising from the lower posterior bladder, hydronephrosis, megaureters, and anorectal agenesis with an intestinal blind end adherent to the posterior wall of the uterus. There were no urogenital duplication, hindgut duplication, or urachal abnormalities. The contracted bladder had a full-thickness muscular wall with a trigone and two ureteral orifices while the cystically distended bladder did not have any opening and was lined by a very thin wall. histology of the cystic bladder wall demonstrated typical urothelium, lamina propria and muscularis propria. The pathogenesis and differential diagnosis of cystic bladder distension are discussed.- - - - - - - - - - ranking = 0.2keywords = urinary (Clic here for more details about this article) |
13/353. Spontaneous regression of inflammatory pseudotumor of the urinary bladder.Inflammatory pseudotumor of the urinary bladder is a benign proliferative lesion of the submucosa and its treatment has not yet been established. Here we present a case of spontaneously regressed inflammatory pseudotumor of the urinary bladder.- - - - - - - - - - ranking = 1.2keywords = urinary (Clic here for more details about this article) |
14/353. Combined antegrade and retrograde endoscopic approach for the management of urinary diversion-associated pathology.BACKGROUND: Endourologic management of stones and strictures in patients with a urinary diversion is often cumbersome because of the absence of standard anatomic landmarks. We report on our technique of minimally invasive management of urinary diversion-associated pathology by means of a combined antegrade and retrograde approach. patients AND methods: Five patients with urinary diversion-associated pathology were treated at our institution between May 1997 and October 1998. Their problems were: an obstructing ureteral stone in a man with ureterosigmoidostomy performed for bladder extrophy; two men with a valve stricture in their hemiKock urinary diversions; an anastomotic stricture in a man with an ileal loop diversion; and a long left ureteroenteric stricture in a man with a right colon pouch diversion. After percutaneous placement of an guidewire across the area of interest, the targeted pathology was accessed via a retrograde approach using standard semirigid or flexible fiberoptic endoscopes. Postoperative follow-up with intravenous urography, differential renal scan, or both was performed at 3 to 24 months (mean 12 months). RESULTS: The combined antegrade and retrograde approach allowed successful access to pathologic areas in all patients. holmium laser/Acucise incision of stenotic segments or ballistic fragmentation of stones was achieved in all cases without perioperative complications. None of the strictures with an initially successful outcome has recurred; however, in one patient, the procedure failed as soon as the internal stent was removed. The patient with the ureteral calculus remains stone free, and his ureterosigmoidostomy is patent without evidence of obstruction on his last imaging study, 24 months postoperatively. CONCLUSIONS: Combined antegrade and retrograde endoscopic access to the area of interest is our preferred method of approaching pathologic problems in patients with a urinary diversion. An antegrade nephrostogram provides better delineation of anatomy, while through-and-through access enables rapid and easier identification of stenotic segments that may be hidden by mucosal folds. Furthermore, this approach allows the use of larger semirigid or flexible endoscopes in conjunction with more efficient fragmentation devices, resulting in enhanced vision from better irrigation. Finally, an initial endoscopic approach may be preferred because its failure does not compromise the success of future open surgery.- - - - - - - - - - ranking = 1.8keywords = urinary (Clic here for more details about this article) |
15/353. Endoscopic management of prolapsing intravesical ureterocele in an adult female--a case report.The authors present a case of intravesical ureterocele in a female which prolapsed out of the external urethral meatus causing urinary obstruction, and was managed by reduction into the bladder followed by endoincision.- - - - - - - - - - ranking = 0.2keywords = urinary (Clic here for more details about this article) |
16/353. Genitourinary complications of systemic lupus erythematosus.A 14-year-old African-American girl was diagnosed with antiphospholipid-positive systemic lupus erythematosus (SLE) in July 1994. The course was complicated by nephrotic syndrome, sepsis, hemolytic anemia, acute renal failure, saphenous vein thrombosis, cutaneous vasculitis, mesenteric vasculitis, appendicitis, hemorrhagic cystitis, and avascular necrosis of the hips. In August 1997, she developed ovarian and fallopian tube complications secondary to SLE. Genitourinary complications of SLE, however, are uncommon, and ovarian vasculitis has not previously been reported as a complication of SLE. This report describes the course of an adolescent patient with SLE and focuses specifically on her genitourinary complications.- - - - - - - - - - ranking = 1.2keywords = urinary (Clic here for more details about this article) |
17/353. Inflammatory pseudotumor of urinary bladder.A previously healthy 44-year-old male was admitted with the chief complaint of intermittent gross hematuria. On initial ultrasonographic and CT examination, a grossly protruding intravesical tumor was noted and, under the impression of a malignant bladder tumor, transurethral resection was performed. The histological findings were spindle cells with elongated cytoplasm with rare mitotic figures distributed in myxoid stroma, consistent with diagnosis of inflammatory pseudotumor of the bladder. The benign nature of this tumor warrants conservative surgical management, usually consisting of transurethral resection or partial cystectomy. No reports of metastasis have been reported following complete excision. Therefore, any suspicion and recognition of this entity is imperative to avoid performing an irreversible radical procedure.- - - - - - - - - - ranking = 0.8keywords = urinary (Clic here for more details about this article) |
18/353. Primary actinomycosis of the urinary bladder.actinomycosis is caused by bacilli of the actinomyces sp. They are Gram-positive, anaerobic or microaerophilic non-spore-forming bacilli. actinomyces israelii is the most common aetiological agent. A case is reported of primary actinomycosis in the urinary bladder successfully treated with ceftriaxone.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
19/353. Inflammatory pseudotumor of the urinary bladder in a child.The inflammatory pseudotumor of the urinary bladder is rare, especially in children. It is a benign proliferative lesion of the submucosal stroma easily mistaken for a sarcoma clinically, so it should be differentiated from a malignant neoplasm. We report the case of bladder inflammatory pseudotumor in a 7-year-old girl.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
20/353. MRI appearances of bladder endometriosis.endometriosis is characterized by endometrial tissue in ectopic foci outside the uterus. Involvement of the urinary tract is rare, with the bladder being most commonly affected in these cases. Radiologically these lesions, which are usually small, may be difficult to distinguish from intrinsic bladder neoplasia. Four cases of vesical endometriosis are presented with the MRI features that suggest the diagnosis.- - - - - - - - - - ranking = 0.2keywords = urinary (Clic here for more details about this article) |
