Incidence and Treatment of Complications of Bacillus Calmette-Guerin Intravesical Therapy in Superficial Bladder Cancer

Intravesical therapy with bacillus Calmette-Guerin (BCG) has proved to be more effective in the prophylaxis and treatment of superficial bladder tumors and carcinoma in situ than most chemotherapeutic agents. Compared to intravesical chemotherapy, instillations with BCG provoke more local and systemic reactions. In addition to the commonly induced granulomatous inflammatory changes in the bladder, which produce irritative symptoms, this therapy may cause systemic side effects varying from mild malaise and fever to, in rare instances, life-threatening or fatal sepsis. We report the incidence and varieties of toxicities in 2,602 patients treated with intravesical BCG. Side effects are classified according to local and systemic toxicity. Treatment options vary according to the severity of toxicity from delaying or withholding instillations to treatment with antituberculous drugs for up to 6 months. In general, 95% of the patients have no serious side effects. Recognition of risk factors, particularly traumatic catheterization or concurrent cystitis, that result in systemic BCG absorption, as well as the prompt and appropriate treatment of early side effects should significantly decrease the incidence of severe toxicity.

EFFICACY AND SAFETY OF VALRUBICIN FOR THE TREATMENT OF BACILLUS CALMETTE-GUERIN REFRACTORY CARCINOMA IN SITU OF THE BLADDER

Purpose: We assess the efficacy and safety of intravesical valrubicin for the treatment of carcinoma in situ in patients with failure or recurrence after bacillus Calmette-Guerin (BCG) and who othe...

Duplication of the male urethra.

Our experience with 4 male subjects with accessory urethras is reported. The anatomic types, clinical presentations and treatment modalities of urethral duplication are discussed. Our scrutiny of all cases reviewed in the literature led us to classify patients into 3 types, depending upon the anatomic and embryologic features. Type 1 is a complete accessory urethra arising from a separate or confluent opening within the bladder and extending to an external orifice. Type 2 includes accessory urethras that arise from the primary urethra and may or may not extend to a distal orifice. Type 3 is the most unusual anomaly, in which 1 of the duplicated urethras arises from the bladder or proximal urethra and opens onto the perineum.

Segmental renal hypoplasia and hypertension.

The association of hypertension with congenital renal hypoplasia (Ask-Upmark kidney) has been well established. A case is presented that clearly demonstrates the distinctive clinical, roentgenographic and pathologic features. An abnormal production of renin by the affected kidney suggested that the renin-angiotensin-aldosterone axis was involved in the genesis of the hypertension. Hypertension was cured by unilateral nephrectomy.

Mixed Gonadal Dysgenesi

AbstractMixed gonadal dysgenesis is an intersex syndrome characterized by a unilateral streak gonad, persistent mullerian duct structures and ambiguous genitalia. These patients are chromatin negative and exhibit XO/XY mosaicism. The disorder probably results from a cytogenetic error that occurs early in embryogenesis. These patients usually are reared as female subjects but masculinity begins at puberty because of the qualitatively and quantitatively normal testicular androgenic function.The patients are diagnosed on the basis of a Y chromosomal component and the presence of a unilateral testis and contralateral streak gonad at the time of exploratory laparotomy. The testis and the streak gonad should be removed because of the potential development of a gonadoblastoma and the virilization that occurs at puberty.
