A 72-year-old Japanese man was referred to a hospital because of urinary retention. Digital rectal examination revealed a stony, hard nodule in the prostate. A high level of serum PSA was not detected. Prostatic biopsy was performed, and pathological examination indicated adenocarcinoma of the prostate. He was referred to our hospital for treatment. Imaging examinations revealed no metastases (T4N0M0), so we re-evaluated the biopsy specimens. Immunohistochemical examination revealed prostatic small cell carcinoma. His levels of neuron-specific enolase (NSE) and pro-gastrin-releasing peptide (Pro-GRP) were high. We treated him with combination chemotherapy comprising irinotecan and cisplatin, and the treatment waseffective. After four coursesof the chemotherapy, levelsof NSE and Pro-GRP had decreased, and the prostatic mass had decreased in size. Needle rebiopsy of the prostate demonstrated no evidence of malignancy. Adjuvant external beam radiation therapy wasals o performed. The patient iss till alive at 18 month after diagnosis with no evidence of relapse or metastasis of the disease.

Metanephric adenoma is a rare benign renal epithelial tumor. We have experienced two cases of metanephric adenoma. The first case was a left renal tumor found by ultrasonography in a 26-year-old woman. The abdominal computed tomography (CT) revealed a 90 mm mass that was enhanced slightly in the early phase, and enhanced further in the late phase. Laparoscopic radical nephrectomy was performed with suspicion of renal cell carcinoma. The second case was a right renal tumor found by CT imaging for heart disease in a 64-year-old man. An abdominal CT revealed a 30 mm mass that was the same as our findings in the first case. Laparoscopic partial nephrectomy was performed with the suspicion of renal cell carcinoma. In both cases, tumor cells are positive for WT-1 and CD57 in immunohistochemical staining ; the final diagnosis was metanephric adenoma. It is difficult to differentiate metanephric adenoma from renal cell carcinoma by preoperative imaging ; the diagnosis depends on morphological and immunohistochemical profiles.

A 49-year-old female presented complaining of gross hematuria. Cystoscopy and magnetic resonance imaging revealed a papillary tumor on the bladder dome. At biopsy pathology the tumor was diagnosed as adenocarcinoma. We diagnosed the tumor as urachal adenocarcinoma and performed partial cystectomy of bladder dome with en-bloc resection of the urachal ligament up to the umbilicus. In surgical pathology, the tumor had invaded to the fat tissue around the urachal ligament with metastasis to the lymph node. Therefore the tumor was diagnosed as a stage IVA (Sheldon’scategory) urachal adenocarcinoma. After surgery, 6cycles of chemotherapy with TS-1 and cisplatin (CDDP) were performed. There has been no relapse 5years after surgery. This is the first report of successful adjuvant chemotherapy with TS-1/CDDP for advanced urachal adenocarcinoma.

We report a case of recurring foreign bodies in the urinary bladder. A 67-year-old male inserted a foreign body into the urinary bladder during masturbation. Eight months later, he experienced a fever and went to a hospital where ultrasonography revealed a foreign body in his urinary bladder. Then, he was referred to our hospital for surgical treatment. The patient’s surgical record indicated that he had undergone the same operation 3 times in the past thirty years. The inserted foreign body was successfully removed by suprapubic cystotomy, and he was discharged 13 days after the operation. He was also evaluated by psychiatrists, but they diagnosed that he had no mental disorder. To our knowledge, this is the first report on the removal of a foreign body in the urinary bladder four times in the same patient.

Erectile dysfunction following radical prostatectomy (RP) is still a significant burden as a post-operative morbidity, despite advances in nerve-sparing techniques and penile (erectile function) rehabilitation (PR) programs. We assessed the effects of stimulation with the masturbation device "EGG" on enhancement of erectile response along with administration of phospho diesterase type 5 inhibitor. We also studied the change of self-esteem and motivation for continuation of PR after stimulation with EGG. Eight nonresponders for PDE5-I who underwent retropubic RP were enrolled. Patients' median age was 71.5 years old. No patients received adjuvant therapy for prostate cancer. The patients' erectile response in the penile rehabilitation session (masturbation) with PDE5-I+manual stimulation and PDE5-I+stimulation with EGG were evaluated by erection hardness score (EHS). Changes of self-esteem and motivation for penile rehabilitation were assessed by the self-esteem subscale of the Self-Esteem and Relationship (SEAR) questionnaire and one original question, respectively. PDE5-I + stimulation with EGG significantly enhanced EHS compared to PDE5-I+manual stimulation in the eight patients (p=0.027). Transformed score of self-esteem subscale score of SEAR questionnaire was significantly increased in the PR session with EGG compared to the PR session with manual stimulation (p=0.043). Six patients who showed a better erectile response with EGG retained motivation for continuation of PR. PDE5-I+stimulation with EGG improved the erectile response in post-RP patients. EGG as a masturbation device may have a potential for contribution to successful PR.
