Abbreviations & AcronymsAbstract: Premature ejaculation is a common sexual problem, as is erectile dysfunction. We evaluated silodosin, a highly selective a1A-adrenoceptor antagonist, as a new treatment option for premature ejaculation. a1-Adrenoceptor antagonists are widely used for lower urinary tract symptoms, and clinical studies on silodosin have shown excellent clinical efficacy for lower urinary tract symptoms. However, compared with other a1-adrenoceptor antagonists, silodosin appeared to suppress ejaculation in a relatively higher percent of trial participants. This suppression of ejaculation by silodosin suggested its potential for treating premature ejaculation. Consequently, we evaluated the feasibility of off-label silodosin as a new treatment option for premature ejaculation. Eight patients suffering premature ejaculation were treated with silodosin. Silodosin (4 mg) was given 2 h before sexual intercourse. Intravaginal ejaculatory latency time, premature ejaculation profile item, clinical global impression change in premature ejaculation and systemic adverse events were recorded. Intravaginal ejaculatory latency time was significantly prolonged (from 3.4 min to 10.1 min, P = 0.003). All patients answered better (much better) or slightly better for their own premature ejaculation problem compared with pretreatment condition in the clinical global impression change. Premature ejaculation profile also significantly improved. Two (25%), three (37.5%) and seven patients (87.5%) experienced anejaculation, reduced semen volume and discomfort during orgasm, respectively. However, these problems were not of major concern for the participants. No systemic adverse effects were reported. The current results support the possible use of silodosin as a new treatment option for premature ejaculation, and suggest that a placebo controlled study assessing its clinical usefulness would be worthwhile.

A 62-year-old woman presented with right flank pain, and computed tomography (CT) showed bilateral adrenal tumors (right, 8 cm; left, 4 cm). There were no abnormal findings on physical examination, and adrenal hormone levels in serum and urine were within normal limits. Radiological studies showed a right adrenal tumor with intratumoral hemorrhage, a cystic tumor in the left adrenal gland, and no sign of distant metastasis. Because laboratory tests showed normal levels of adrenal hormones, we considered the tumors to be nonfunctioning adrenal tumors. The right adrenal tumor was surgically removed because it was thought to be malignant, and histological examination revealed that it was a leiomyosarcoma. Postoperative CT showed a pleural metastasis in the right chest wall. The patient received combination chemotherapy with cyclophosphamide, vincristine, adriamycin, and dacarbazine. The metastasis was also treated with radiofrequency ablation (RFA). Because the left adrenal tumor grew rapidly despite two courses of the chemotherapy, it too was surgically removed. After the operation, metastasis in the right iliac bone was treated with RFA and radiotherapy. Positron emission tomography detected bilateral femoral metastases, and these were treated with radiotherapy in combination with a low dose of cisplatin. A liver metastasis and a small metastasis in the left kidney were treated with RFA and a metastasis in the pancreatic tail was removed surgically. Sixteen months after the right adrenalectomy, the patient died due to systemic spread of the disease. Multiple local treatments including RFA, radiotherapy, and resection were effective for the local control of metastatic lesions of adrenal leiomyosarcoma.

Methods: A total of 190 patients who had undergone retropubic radical prostatectomy were evaluated. Urine loss ratio was measured using the 24-h pad test during 7 consecutive days after removal of urethral catheters. Continence rates at 1, 3, 6 and 12 months after operation were evaluated with the urinary function domain of the University of California, Los Angeles Prostate Cancer Index. The desirable urine loss ratio for continent condition at 12 months after the operation was calculated. As desirable target urine loss ratio continence at 12 months was determined by using logistic analysis. Results: Continence rates of all patients at 1, 3, 6 and 12 months after surgery were 13%, 37.8%, 58.9%, and 85.8%, respectively. Continence rates of patients who achieved ≤1% of urine loss ratio within 7 days or ≤5% urine loss ratio within 3 days after catheter removal was 100% at 12 months. Logistic regression analysis proved these urine loss ratio values were significant predictors of continence at 12 months. Conclusions: Urine loss ratio after catheter removal within 7 days is a significant determinant of urinary continence after radical prostatectomy. This parameter could have clinical usefulness to estimate future recovery of urinary continence.

Silodosin, a highly selective α1A-adrenoceptor antagonist, produces greater improvements in premature ejaculation profiles and related symptoms along with intravaginal ejaculation latency time in acquired premature ejaculation patients with or without erectile dysfunction. This result supports the clinical use of silodosin as an alternative treatment for premature ejaculation.

Methods: A total of 162 patients who underwent retropubic radical prostatectomy and their partners were evaluated. The patients' sexual function, sexual bother and expectations for postoperative sexual life were assessed prospectively at baseline, and at 1, 3, 6 and 12 months after radical prostatectomy. The partner was asked questions about postoperative sexual life before the operation. Sexual function and sexual bother were evaluated by the University of California Los Angeles Prostate Cancer Index. Expectations for postoperative sexual life were studied using three ad hoc questions. Results: The rate of having sexual intercourse and adequate penile rigidity for vaginal penetration at baseline was 29.0% and 21.6%, respectively. A significantly higher rate of patients considered "sexual life is important" (patient 35.2%, partner 13.0%), hoped for "preservation of erectile function" (patient 66.0%, partner 33.3%) and accepted "use of phosphodiesterase type 5 inhibitor" (patient 65.4%, partner 43.2%) compared with their partners (P < 0.001). Patients who had partners with a negative sexual attitude lost sexual motivation 1 year after operation. However, patients with cooperative partners maintained sexual motivation, although they felt greater sexual bother 1 year after radical prostatectomy. Conclusions: There was a significant dissociation in perspectives of postoperative sexual life between patients undergoing radical prostatectomy and their partners. Partners' low expectations are associated with patients' low sexual bother and motivation. Partners' cooperative attitude might contribute to maintaining patients' sexual desire and motivation.

We report a rare case of primary amelanotic malignant melanoma of the female urethra. A 58-year-old female with complaint of nodule on the external urethral meatus was referred to our hospital. Pathological diagnosis of the biopsy specimen from the nodule was malignant melanoma. Computed tomography of the chest and abdomen as well as bone scan showed no evidence of metastasis. Sentinel biopsy from the inguinal lymph nodes revealed no metastasis. Thereafter, the patient underwent radical urethrectomy, whose limits of resection were the bulbocavernosal muscles bilaterally, the arch of the pubic symphysis anteriorly, the anterior vaginal wall posteriorly, and the urethra up to the level of the bladder neck superiorly. The histopathological diagnosis was amelanotic malignant melanoma of the urethra. The patient had received six cycles of DAV-Feron (dacarbazine, nimustine, vincristine, and interferon-beta) in an adjuvant setting, and there is no sign of recurrence 25 months after operation.

A 66-year-old man visited his nearby clinic with a complaint of left lower abdominal pain. Abdominal CT scan showed left hydronephrosis due to lower ureteral involvement by infiltrative retroperitoneal mass located outside of the left posterior wall of the bladder and left seminal vesicle. He was referred to our hospital for further examination. Pathological diagnosis of the percutaneous CT-guided biopsy of retroperitoneal mass was fibrosis without any malignant tumor. Because we could not rule out the possibility of the secondary fibrosis accompanied by malignant tumor, we performed surgical resection of the retroperitoneal mass involving left ureter and confirmed that the mass contains no malignant tumor by frozen section analysis. We augmented the defected ureter by Boari flap method. We should be noticed that retroperitoneal fibrosis could be a differential diagnosis of retroperitoneal pelvic mass.
