Vesicourethral Anastomotic Suture Placement during Radical Prostatectomy Using Maniceps

Introduction: A new method of using a semiautomatic device (Maniceps) for precise vesicourethral anastomosis during radical retropubic prostatectomy is described. Methods: A total of 15 patients underwent radical retropubic prostatectomy with this technique. The follow-up period ranged from 6 to 16 months. The retrograde urethrocystography was performed at 2 weeks. Patients were evaluated specifically for anastomotic time, anastomotic obstruction and urinary continence. Results: The average anastomotic time was 8.1 (range 5–12) min. The catheter of all patients could be removed at 2 weeks. Anastomotic obstruction occurred in 1 patient (6.7%), and 14 patients (93.3%) were completely continent of urine. Conclusion: Maniceps is a useful procedure to carry out vesicourethral anastomosis safely, easily and surely, and it has provided good surgical results in our experience.

Further investigation of the epitope recognized by the new monoclonal antibody 2C9

Objective:  We established a new monoclonal antibody (2C9) that reacted with prostate tissue. The immunohistochemical reactivity of this antibody is similar to anti‐prostate‐specific membrane antigen (PSMA). Herein, we report the antigenic determinant of 2C9 antibody.

Clinical features of renal cell carcinoma less than 25 millimeters in diameter

Background: We retrospectively investigated the clinicopathological features and prognosis of patients who underwent surgical treatment at our department for renal cell carcinoma (RCC) less than 25 mm in diameter.

Endoscope-assisted minilaparotomic radical retropubic prostatectomy

Objective:  To assess the clinical efficacy of endoscope‐assisted minilaparotomic radical retropubic prostatectomy (EAM‐RRP) compared with conventional radical retropubic prostatectomy (cRRP).
