Study Type – Therapy (case series)
 Level of Evidence 4 OBJECTIVE To present experience in high‐intensity focused ultrasound (HIFU) used as a salvage therapy for biopsy‐confirmed local recurrence at the vesico‐urethral anastomosis after radical prostatectomy (RP). PATIENTS AND METHODS From July 2006, four patients diagnosed with prostate cancer recurrence after RP were treated with HIFU, with or without salvage radiotherapy, using the Sonablate® 500 (Focus Surgery, IN, USA). Biochemical failure was defined as in increase in prostate‐specific antigen (PSA) level of >0.2 ng/mL. No patients received any adjuvant therapy after HIFU therapy before reporting failure. RESULTS The mean age and initial PSA level before RP was 74 years and 10.0 ng/mL, respectively. After RP, one patient was stage T2aN0M0, two were stage T3N0M0 and the last had an unknown pathological stage. Three patients received external beam radiotherapy as salvage therapy after RP. The mean PSA level before HIFU, tumour volume at the vesico‐urethral lesion and operative duration were 4.3 ng/mL, 4.6 mL and 27 min, respectively. Adenocarcinomas were confirmed by biopsy of the tumour at the vesico‐urethral anastomotic lesion before HIFU. At 24 months of follow‐up, patients 2 and 4 were classified a biochemically disease‐free. Biopsies at the anastomotic site after HIFU in three patients showed no malignancy, with fibrosis. There were no complications. CONCLUSION Salvage HIFU for patients with recurrence after RP is feasible, even though they received salvage radiotherapy before HIFU. More patients and a longer follow‐up are needed to evaluate the safety and oncological adequacy of this new approach.

Aim:We assessed the efficacy of a third generation extracorporeal shock wave lithotripsy (ESWL) machine for ureter stones using the Dornier Lithotriptor Compact Delta. Methods: A total of 471 consecutive ureter stones were treated with ESWL using the Dornier Lithotriptor Compact Delta from December 2001 on an outpatient basis. Four hundred and one cases were followed up at least once after the procedure and were included in this study. All of the cases, except one patient who was three years old , were treated without anesthesia, and the procedure was principally performed on outpatient basis. Results: The overall stone free rate was 94.5% and the mean number of treatment sessions was 1.23. The stone free rates were compared considering various clinical factors and significant differences were observed in the stone length, the stone location and the sex in univariate analysis. However, only the stone length maintained a statistically significant impact in multivariate analysis and the stone free rates were 91.2% and 98.0% respectively in larger stones (length 10mm) and smaller stones (length < 10mm) (p = 0.004). In mid-distal stones, the stone free rate was higher than that of proximal stones (97.5% vs 92.6%, p = 0.04) and not affected by stone length. Conclusions: Extracorporeal shock wave lithotripsy performed by the third generation machine achieved an excellent stone free rate with a relatively small number of treatment sessions. This procedure is strongly recommended as the first line therapy for all ureter stones including mid-distal ones.

The symptoms of women with lower urinary tract disorders were frequently accompanied by urethral and/or pelvic floor abnormalities during voiding that were clearly detected by VU-TRUS. VU-TRUS is useful for objective evaluation of female lower urinary tract symptoms.

A 52-year-old unmarried bag craftsman was admitted to East Tokyo Metropolitan Hospital because of a large scrotal hematoma. He had accidentally hit his right testis against the edge of a desk early the previous morning. He had resected his right testis with scissors to release from severe pain 30 min after the accident. He had sutured the scrotal incision with two stitches of string by himself.At the emergency operation 36 h after the self-mutilation, we removed a hematoma weighing 283 g and ligated the cut end of the right spermatic cord after adequate debridement. He was diagnosed by a psychiatrist as having slightly low intelligence without psychotic disorder or drug abuse.
