Hemorrhagic Cystitis due to Intravesical Instillation of Gentian Violet Completely Recovered with Conservative Therapy

Chemical cystitis due to intravesical instillation of gentian violet or crystal violet is rare and all of the reported cases have been in adults using undiluted solution, which resulted in long-term sequelae. This is a case report on a 16-month-old boy with hemorrhagic cystitis after the instillation of diluted gentian violet into the bladder to rule out bladder injury during inguinal herniorrhaphy. Although he was completely recovered with conservative therapy, gentian violet, even when diluted, should not be used on the urinary tract.

Retroperitoneal Cystic Lymphangioma Simultaneously Diagnosed with Bladder Cancer / 대한비뇨기과학회지

Lymphangiomas are rare benign tumors of the lymphatic system. They usually occur in the neck or axillary region, whereas the retroperitoneum is one of the least frequent sites. The treatment of choice is complete surgical excision. We report a case of a 56-year-old man who had a retroperitoneal cystic lymphangioma in combination with bladder cancer. After complete surgical excision of the retroperitoneal lymphangioma with transurethral resection of the bladder tumor followed by intravesical BCG immunotherapy, the patient remained free of recurrence at 1 year after treatment.

A Case of Spontaneous Rupture of Renal Pelvis without Identifiable Cause Treated Conservatively / 대한비뇨기과학회지
