Bladder leiomyoma: a rare cause of urinary stress incontinence.

Lejomyoma of the bladder is an uncommon lesion and usually present as small intramural or submucosal lesions. Preoperative evaluation based on careful physical and radiologic examinations must rule out malignant and other lesions. It is readily and successfully treated in most cases with transurethral or open resection. The prognosis of this tumor is excellent and no malignant degeneration has been reported. The most common presentations are obstructive voiding symptoms, irritative symptoms, and hematuria. Occasionally, it may be a cause of urinary stress incontinence. Although this condition is rare, it should be considered in the causes of urinary stress incontinence.

Use of new automated biopsy device for percutaneous testicular biopsy. A preliminary clinical experience.

Testicular biopsy is indicated in the azoospermic patients to determine if the cause of azoospermia is ductal obstruction or testicular pathology and in certain patients who have severe oligozoospermia. The technique traditionally used is an open testicular biopsy. New Automated Biopsy Device has been used successfully for renal diseases. This instrument is now used by the urologist for transrectal prostate biopsy. The aim of this study was to evaluate whether percutaneous testicular needle biopsy with new automated device can replace open testis biopsy or not. 90 testes of 48 patients between 22 and 43 years olf underwent percutaneous testicular biopsy with a new 18-gauge automated biopsy device. Adequate samples were recovered from 90% cases (average 24.77 tubule sections per testis). When needle biopsy and open biopsy samples were compared in 30 testes of 15 patients, complete agreement was obtained in 93%, whereas slight differences in 7%. These results show that percutaneous needle biopsy with new automated systems is cost-effective, quick, safe, repeatable, relatively painless and effective way to obtain largest possible cores through full cut technique. No serious complications were encountered during or after the procedure. The diagnosis were found to be comparable to those obtained by open biopsy. For these reasons, it is concluded that this new technique can replace the open biopsy.

Renal cell carcinoma in a giant renal cyst. A case report and review of the literature.

A case of renal carcinoma in a giant solitary renal cyst is reported. Ultrasonography and CT showed an apparently benign left renal cyst except for wall irregularity. Cytological examination and fat analysis of the cyst content were negative but the fluid was haemorrhagic in nature. Frozen section of the cyst wall revealed malignancy and further histopathologic examination indicated renal cell carcinoma.

Systemic absorption of gentamicin in penile prosthesis operations.

Irrigation with antibiotic solutions is frequently used in penile prosthesis surgery to avoid infection. We carried out a prospective study to determine the degree of absorption of gentamicin after intracavernous irrigation in 10 patients who underwent penile implantation surgery. All obtained values were below the toxic level of 10 micrograms/ml and decreased gradually within a few hours. We concluded that highly concentrated gentamicin solutions could be used with safety for intracavernous irrigation.

Eosinophilic cystitis induced by mitomycin-C.

Eosinophilic cystitis is an unusual form of cystitis which is characterized by irritative voiding symptoms and haematuria. In the report herein two adult cases of eosinophilic cystitis treated with intravesical Mitomycin-C instillations for prophylaxis of bladder carcinoma are presented and the literature is reviewed.
