Bladder endometriosis (BE) is rare. Deep invasive endometriosis is difficult to control with medications alone; such cases need surgical treatment. Good results of laparoscopic partial cystectomy with a transurethral (TU) resectoscope by the see-through technique for patients with BE are reported. Materials and Methods: From January 2008 to February 2016, 12 cases of symptomatic BE were seen in our institution. The chief complaints of 9 cases were micturition pain during menstruation. Preoperative cystoscopy showed a bladder mass with blueberry spots. All surgeries were performed under general anesthesia. Laparoscopic surgery was performed with a fan of 4 ports in the lower abdomen. First, the uterus and bilateral ovaries were checked. Then, the TU resectoscope was inserted. When the affected bladder wall was identified, it was again observed with the laparoscopic light source off, which made it possible to observe the twilight leaking inside from the bladder. This twilight came from the light source of the TU resectoscope via the unaffected bladder wall. In contrast, the thickness of the affected wall prevented the light from inside the bladder from passing through it. We call this the "see-through technique." The tumor was then safely dissected with both laparoscopic and TU resection procedures. Finally, the bladder was sutured by laparoscopic procedures using absorbable sterile surgical suture. The urethral catheter was removed after cystography 7 days after the operation. Results: The surgical margins of all cases were negative. There has been no recurrence of BE so far in any patients. There were no major adverse events perioperatively and the urinary symptoms improved in all cases. Conclusions: By laparoscopic partial cystectomy assisted with a TU resectoscope and see-through technique, the edge of BE could be easily and precisely identified. These procedures are effective and safe for BE surgical treatment.

Introduction: Transurethral resection of the prostate (TURP) is the gold standard for surgical treatment of benign prostatic hyperplasia (BPH), but it has complications such as bleeding and transurethral resection syndrome. The treatment results of TURP performed by non-Japanese board-certified urologists were examined, and the results were analyzed according to the resection volume to determine how much resection volume was suitable for non-Japanese board-certified urologists. Materials and Methods:A total of 72 cases that underwent TURP for BPH at our hospital were examined. The patients were divided into three groups by resection volume (<20 g, 20 30 g, >30 g). The operators were five non-Japanese board-certified urologists. Various clinical factors were examined among the three groups before and after TURP. Results:The average operation time and resection volume were significantly different among the groups. There were more transfused cases with greater resection volume. The changes from before to after TURP in the International Prostate Symptom Score, total prostate volume, and maximum flow rate were significantly different among the three groups, but the rates of these changes were not. Conclusions:In this study, TURP performed by non-Japanese board-certified urologists was relatively safe and achieved sufficient efficacy. Cases with resection volume less than 20 g appear the most appropriate for non-Japanese board-certified urologists. (J Nippon Med Sch 2017; 84: 73 78)

A 73-year-old man presented with right lower back pain and dysuria. Right hydronephrosis and a large pelvic large mass were seen on computed tomography (CT). Although his prostate-specific antigen (PSA) was 0.5 ng/mL, an irregularly enlarged, stony, hard prostate was palpable on digital rectal examination. A prostate tumor was suspected, and a transrectal prostate biopsy and right transurethral ureteral stent placement were performed. Histological and immunohistochemical studies revealed diffuse large B-cell lymphoma. Positron emission tomography-computed tomography showed abnormal uptake in the stomach, cecum, right obturator lymph nodes, para-aortic lymph nodes, and dorsal left kidney. No abnormal findings were seen on bone marrow histology. Clinical stage IVA was confirmed according to Ann Arbor criteria. The patient achieved a complete response after 8 cycles of combination chemotherapy with rituximab, pirarubicin, cyclophosphamide, vincristine, and prednisolone. (J Nippon Med Sch 2018; 85: 236 240)

there was no significant change in the OABSS, the improvement in IPSS suggests that subjective voiding symptoms have improved.Although the maximum urinary flow rate did not change significantly, the bladder volume at first sensation increased, urinary storage function improved, and residual urine volume decreased. There were no perioperative complications, and none of the patients complained of post-operative difficulty in urination or urinary retention. The retrovesical angle significantly decreased.Conclusions: The modified LSC in women with POP provides good functional outcomes in terms of IPSS, post void residual volume (PVR), and urinary storage function.
