Add-on anticholinergic therapy for residual nocturia in patients with lower urinary tract symptoms receiving α1-blocker treatment: a multi-centre, prospective, randomised study.

Purpose: To evaluate the efficacy and safety of imidafenacin (IM), a novel short half-life anticholinergic, as add-on therapy for male LUTS with nocturia and nocturnal polyuria.

Materials And Methods: This multicenter, prospective, randomized, open-labelled study was conducted and involved men who had frequency, urgency, and nocturia despite receiving a stable dose of α1-blocker for ≥1 month. Subjects were randomised to control (α1-blocker alone), IM twice/day (α1-blocker +0.

Pathological outcomes of Japanese men eligible for active surveillance after radical prostatectomy.

Background: The aim of this study was to analyze the pathological features of prostatectomy specimens from patients with low-risk prostate cancer eligible for active surveillance (AS) and evaluate preoperative data suitable for predicting upstaged (≥pT3) or upgraded disease (Gleason score of ≥7), defined as 'reclassification'.

Methods: A retrospective analysis of 521 consecutive radical prostatectomy procedures (January 2005 through to December 2011) performed at our institution without neoadjuvant hormonal therapy was performed. Eighty-four patients fulfilled the following criteria-clinical T1 or T2 disease, prostate-specific antigen (PSA) level of ≤10 ng/ml, one or two positive biopsies, and Gleason score of <7.

[A case of inflammatory myofibroblastic tumor of the urinary bladder].

A 61 year-old man complaining of asymptomatic gross hematuria was admitted to our hospital in May 2005. Transurethral resection of bladder tumor (TUR-BT) was performed for a bladder tumor (urothelial carcinoma (UC), pTa, G2). The TUR-BT was performed again because cystoscopy revealed a nonpapillary bladder tumor on the posterior bladder wall in September 2007.

Surgical treatment of female stress urinary incontinence with a transobturator tape (Monarc): short-term results of a prospective multicenter study.

Aim: Transobturator tape (TOT) kits approved as medical instruments are still not available in Japan. This study aimed to: (1) assess the outcomes of TOT using Monarc (American Medical Systems; AMS Inc, Minnetonka, MN, USA) in women with stress urinary incontinence (SUI); (2) evaluate possible different surgical outcomes in women with urethral hypermobility (UH) and/or intrinsic urethral deficiency (ISD); and (3) evaluate the possibility of improvement of preoperative urgency and urge urinary incontinence after TOT in mixed urinary incontinence (MUI).

Methods: Data from 140 women with SUI in a prospective multicenter study were examined at 3-6 months follow-up.

Complications of urologic laparoscopic surgery: a single institute experience of 1017 procedures.

Purpose: We evaluated complications of urologic laparoscopic surgery at our institution.

Patients And Methods: From December 1991 to January 2009, 1017 urologic laparoscopic surgical procedures were performed in Kansai Medical University, including 277 radical prostatectomies, 13 donor nephrectomies, 74 partial nephrectomies, 158 radical nephrectomies, 55 pyeloplasties, 97 nephrouretectomies, 54 simple nephrectomies, 128 adrenalectomies, 34 varicocelectomies, and 127 other procedures. Medical records of each procedure were retrospectively evaluated.

[Small cell carcinoma of the prostate: a case report].

A 76-year-old man had been treated with maximum androgen blockade therapy for a poorly-differentiated prostate adenocarcinoma (T3cN1M0, prostate specific antigen (PSA) 65 ng/ml, Gleason Score 4+5=9) since September 2002. By August 2003, his serum PSA levels were undetectable and the lymph node swelling had vanished. However, in December 2004, his serum PSA levels started rising gradually up to 0.

[Laparoscopic sacrocolpopexy for post-hysterectomy vaginal vault prolapse].

Laproscopic sacrocolpopexy offers a minimally invasive approach to correct post-hysterectomy vaginal vault prolapses. Herein we present our surgical technique and results. Through the transperitoneal approach, the retroperitoneal space was dissected along the right edge of the rectum and a polypropylene mesh is sutured to the vaginal apex and the anterior longitudinal ligament of the sacrum.

Retroperitoneoscopic partial nephrectomy with transient occlusion of renal artery for treatment of small renal tumors.

Objectives: To evaluate the results of retroperitoneoscopic partial nephrectomy with transient occlusion of the renal artery for treatment of patients with small renal tumors.

Methods: From May 2002 to March 2003, 12 consecutive patients with T1N0M0 renal tumors with a median diameter of 3.0 cm underwent retroperitoneoscopic partial nephrectomy.

Retroperitoneoscopic partial nephrectomy using microwave coagulation for small renal tumors.

Objectives: The outcome of laparoscopic partial nephrectomy using a microwave tissue coagulator for treatment of small renal tumors was studied.

Patients And Methods: From June 1999 to May 2001, eight patients with small renal tumors of less than 5.0cm in diameter (1.

[The experience of laparoscopic radical nephrectomy for renal tumors].

We evaluate the safety and feasibility of laparoscopic radical nephrectomy for renal tumors. Between September 1993 and October 2001, 18 patients with renal tumors underwent laparoscopic radical nephrectomy. The mean patient age was 57.

[A clinical analysis of patients with early-stage prostate cancer managed without initial treatment].

To search for a more suitable qualification indicating watchful waiting, we performed a retrospective study against early-stage prostate cancer patients managed without initial treatment. Thirty-three patients who had not been treated for more than 6 months after diagnosed as T1c or T2 prostate cancer were studied. The median values of total observation period, age at diagnosis, and initial PSA were 27.
