ABSTRACT: The patient was a 35-year-old woman with complaints of residual sensation and pollakisuria. Excretory urography and magnetic resonance imaging revealed right ureterocele with hydronephrosis. Transurethral incision of the ureterocele was carried out. Two months postoperatively, the ureterocele prolapsed through the external urethral meatus, and transurethral resection of ureterocele was performed. Forty-one cases of prolapsed ureterocele reported in the Japanese literature are reviewed.

ABSTRACT: A 12-year-old girl was referred to the National Hospital Organization Nara Hospital complaining of dysuria and lower abdominal pain. On examination of the external genitalia, vaginal opening was closed completely. Ultrasonography and magnetic resonance imaging revealed atresia hymenalis with hematocolpos. Hymenal incision was carried out and clinical symptoms were improved. Seventy-eight cases of atresia hymenalis reported in the Japanese literature since 1987 are reviewed. It is necessary to include atresia hymenalis in diagnosis of voiding difficulty in pubescent girls.

ABSTRACT: A 35-year-old woman, who had a past history of hypertension due to paraganglioma of the urinary bladder and in the pelvis, was referred to us 12 years after the initial diagnosis of paraganglioma. Before coming to us and during the follow-up after enucleation of myoma uteri, she was again diagnosed as having a bladder tumor by a gynecologist. Cystoscopy revealed a non-papillary broad-based tumor, measuring 2 cm in diameter, on the trigone of the urinary bladder. Magnetic resonance imaging also showed two solid tumors, each measuring 2 cm in diameter, on the bilateral peri-vesical sides in the pelvis. Endocrinologic examination disclosed increased levels of serum and urinary catecholamines. Histopathologic examination revealed that the bladder tumor specimen obtained by transurethral resection was paraganglioma. She underwent partial cystectomy and resection of these intrapelvic tumors via a retroperitoneal approach. These tumors were histopathologically diagnosed as multiple paragangliomas. She has been followed up for 10 months after operation without any evidence of recurrence. Herein, we report this rare case of vesical paraganglioma and present a brief review of the relevant literature.

ABSTRACT: Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant disorder characterized by an excess of extracolonic malignancies including those of the urinary tract. We report a case of metachronous bilateral ureteral cancer associated with HNPCC. A 51-year-old man was referred to Nara National Hospital for further examination of left hydronephrosis on excretory urography performed on the periodical follow-up for colon cancer. Computed tomography showed a mass in the left lower ureter and urine cytology was demonstrated class V. The operation was performed under the diagnosis of left ureteral cancer. The histopathological diagnosis was transitional cell carcinoma, grade 2, pT1. After 4 months of the operation, he presented with gross hematuria. Retrograde pyelography demonstrated tumors in the right side (ureter and renal pelvis) and the histopathological diagnosis of the biopsy specimens revealed transitional cell carcinoma, grade 2. We performed 4 times of BCG instillation followed by laser ablation of the tumor. The reported case was compatible for Japanese clinical criteria, group B for HNPCC.

ABSTRACT: A 61-year-old man presented to our hospital with a 1.5-year history of a gradually enlarging mass in the left scrotum. The mass was apart from the testis and fixed to the spermatic cord. The firm consistency and heterogeneous expression on ultrasonography suggested a malignant tumor. Orchiectomy with high ligation of the spermatic cord was performed and a histological examination revealed leiomyosarcoma of the spermatic cord. Distant metastases were not observed. Because the incidence of local recurrence has been reported to be high, we performed irradiation to control the disease. At 32 months post-surgery he was alive with no evidence of disease.
