1/110. A successfully treated case of condyloma acuminatum of the urethra and urinary bladder.Condyloma acuminatum very seldom affects the urinary bladder, but if it does conservative treatment has been considered of little value and cystourethrectomy will eventually be required. A case with urethrovesical condyloma is presented, where repeated transurethral resections cured the patient.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
2/110. Angiomyofibroblastoma of the female urethra.BACKGROUND: Angiomyofibroblastoma is a relatively recently described rare tumor of the superficial soft tissues. To date, 57 cases of angiomyofibroblastoma of the external genitalia in women have been reported. methods/RESULTS: We describe a case of a 24-year-old woman who presented with the urinary stream flowing out in the posterior direction and whose diagnosis was a urethral tumor, angiomyofibroblastoma. CONCLUSIONS: Angiomyofibroblastoma has a potential arising from the female urethra as well as other areas of the external genitalia.- - - - - - - - - - ranking = 0.2keywords = urinary (Clic here for more details about this article) |
3/110. Nephrogenic adenoma mimicking carcinoma: a potential pitfall in cytodiagnosis.Nephrogenic adenoma of the urinary bladder and urethra is an uncommon benign lesion of the urinary epithelium that can cytologically and histologically mimic malignancy. We report on the cytologic findings of a case of nephrogenic adenoma of the urethra that mimicked malignancy in an 84-yr-old woman. The differential diagnosis of this problematic lesion is discussed, and the literature describing the cytologic features is reviewed.- - - - - - - - - - ranking = 0.4keywords = urinary (Clic here for more details about this article) |
4/110. collagen polyp of the urinary tract: a report of two cases.Injection of collagen into the urethral or bladder wall has gained popularity as an effective way to control urinary stress incontinence. The same technique has recently been used to improve function of urinary pouches surgically created from intestinal segments. We report the first two cases of a polypoid lesion in these structures, both of which were composed of injected collagen. The first lesion occurred in the ileal urinary pouch of a 41-year-old paraplegic man who had cystoprostatectomy for severe spasm and repeated infection of the bladder. The pouch, removed for repeated infection, showed a 2.5-cm submucosal polyp. The second lesion was in the urethra of a 71-year-old man who underwent radical retropubic prostatectomy for prostatic carcinoma, followed by artificial urethral sphincter placement. Follow-up cystoscopy revealed a proximal urethral polyp that was biopsied. In both cases, collagen was injected into these structures for controlling urinary incontinence. Histologically, the polyps were caused by submucosal accumulation of injected collagen with pathognomonic features (i.e., eosinophilic, homogeneous, and poorly cellular material that was faintly positive by the periodic acid-Schiff and strongly positive by the trichome stain). These two cases expand the list of differential diagnoses for a polypoid lesion in the intestinal and urinary tracts and illustrate the morphology of injected collagen. A familiarity with these changes is diagnostically helpful because an increasing number of specimens removed for therapeutic failure of injected collagen are expected.- - - - - - - - - - ranking = 1.8keywords = urinary (Clic here for more details about this article) |
5/110. Carcinoma in diverticulum of female urethra.A case of female urethral diverticulum is reported by the authors. It is a rare disease and about 31 cases have previously been described. An analysis is made in relation to the diverticulum of the urethra and to female urethral carcinoma. Emphasis is given on the semiology and the recently acquired diagnostic procedures, as these have led to an increased number of recognized cases. In the case presented, an extended resection and a definitive urinary derivation was performed, together with chemo- and radiotherapy. A follow-up of 2.5 years showed no signs of recurrence or metastases.- - - - - - - - - - ranking = 0.2keywords = urinary (Clic here for more details about this article) |

7/110. Villous adenomas of the urinary tract: report of two cases.Villous adenomas are rare tumors of the urinary tract. They are morphologically identical to their counterpart in the colon. The histogenesis and malignant potential are uncertain. We report on 2 cases, 1 each in the urethra and bladder. The first is a 57-year-old male who complained of an acute attack of urinary retention. A papillary tumor, measuring 3.0 x 2.0 cm, was found in the prostatic portion of the urethra by cystoscopy, and the tumor was removed transurethrally. The second case, a 33-year-old male, was a victim of chronic pyelonephritis with severe hydronephrosis resulting from a left renal staghorn stone. A papillary tumor was noted on the dome of the urinary bladder. The tumor, measuring 2.0 x 2.0 cm, was resected by transurethral resection. No recurrence or malignant transformation has been found during the follow-up period. The features of morphology, immunohistochemistry, and histochemistry were well studied. Staining by periodic acid-Schiff (PAS) stain, alcian blue at pH 1.0, and alcian blue at pH 2.5 were all positive. The carcinoembryonic antigen was strongly positive in the neoplastic glands, especially in the luminal border. We also review the previous literature and discuss the histogenesis, diagnosis, and treatment.- - - - - - - - - - ranking = 1.4keywords = urinary (Clic here for more details about this article) |
8/110. leiomyoma of the female urethra with upper tract dilation and treatment with transurethral resection: a case report and literature review.leiomyoma of the female urethra is a rare condition. It is a benign mesenchymal tumor that commonly presents with recurrent urinary tract infections and various lower urinary tract symptoms. We report a case of urethral leiomyoma and review the literature. A 44-year-old woman presented with severe irritative voiding symptoms without urinary tract infection and bilateral upper urinary tract dilation. Ultrasound and cystoscopy revealed a smooth mass arising from the urethra and projecting into the bladder. Transurethral resection of the mass was performed and 32 g of tissue was removed. There were no complications and the symptoms resolved completely, indicating this to be a safe approach. Histopathology showed the tumor to be leiomyoma.- - - - - - - - - - ranking = 0.8keywords = urinary (Clic here for more details about this article) |
9/110. A long-term course of a primary urethral/paraurethral adenocarcinoma.The authors report a rare case of primary urethral/paraurethral adenocarcinoma in a female patient. The tumor was first detected at the external and internal urethral orifices, with later recurrences in the region of the urinary bladder neck. histology did not reveal the exact origin of the malignancy. The patient was treated by transurethral resection, regularly repeated during the 3-6-monthly checks. Five years after diagnosis she remains symptom free and has a high quality of life.- - - - - - - - - - ranking = 0.2keywords = urinary (Clic here for more details about this article) |
10/110. MRI appearance of a leiomyoma of the female urethra.Leiomyomas are rare in the urinary tract, with the kidney capsule being the most common location [1]. leiomyoma of the female urethra is very rare. In 1992, Cheng et al. reviewed a total of 29 cases. They concluded that urethral leiomyoma is a rare condition that is difficult to distinguish clinically from other urethral lesions and that a histological diagnosis is essential [2]. Although we agree that the histological diagnosis is essential, magnetic resonance imaging (MRI) provides useful pre-operative information in cases of leiomyoma of the female urethra, as our present case indicates. To our knowledge we report the second case of a primarily diagnostic approach with MRI for leiomyoma of the female urethra. Ikeda, R. (2001).
