Objective: The purpose of this study was to evaluate symptomatic bone metastases from urological malignancies and the efficacy of surgical treatment of bone metastases in achieving local tumor control.

Methods: This was a retrospective observational study of patients diagnosed with bone metastases from urological malignancies who died from their diseases between 2002 and 2013. Data on clinicopathology, number and sites of bone metastasis, time to first and subsequent metastasis, survival after metastasis, nature of metastasis (blastic, mixed, lytic), type of surgical reconstruction, systemic affections, and visceral organ metastasis for 70 bone metastases from deceased urological malignancies patients (55 male, 15 female) with evidence of bone metastasis were statistically analyzed.

Introduction: Several studies evaluating the tolerance of transrectal ultrasound (TRUS)-guided needle biopsies showed that moderate-to-severe pain was associated with the procedure. Additionally, prebiopsy anxiety or rebiopsy as a result of a prior biopsy procedure is mentioned as factors predisposing to higher pain intensity. Thus, in this study, we investigated the effects of hypnotherapy during transrectal ultrasound-guided prostate needle biopsy for pain and anxiety.

Purpose: To investigate the efficacy of a novel anesthetic technique called iliohypogastric nerve block (INB) for pain control in patients undergoing prostate biopsy.

Materials And Methods: A total of 59 consecutive patients who underwent transrectal ultrasound guided prostates biopsies were included in the study. Patients were randomized into four groups: (1) control, no method of anesthesia was administered, (2) intrarectal prilocaine-lidocaine cream application, (3) INB and (4) INB + intrarectal prilocaine-lidocaine cream application (combined group).

Purpose: We evaluated the effect of diabetes mellitus on incontinence after laparoscopic radical prostatectomy.

Materials And Methods: From a series of 2,071 patients 135 with type 2 diabetes mellitus undergoing laparoscopic radical prostatectomy without radiotherapy and with a minimum followup of 24 months were identified. These patients were randomly matched with 135 nondiabetic controls for age, body mass index, preoperative prostate specific antigen, clinical stage, neoadjuvant hormonal therapy, prostate volume, previous surgery, surgeon skills, surgical approach, presence of bladder neck sparing, lymphadenectomy, technique of urethrovesical anastomosis and attempted nerve sparing surgery.

Objective: Tadalafil is a selective phosphodiesterase type 5 (PDE-5) inhibitor approved for the treatment of erectile dysfunction. Less is known about the electroencephalography (EEG) effects of PDE-5 inhibitors, and the present study, therefore, examined the risk of EEG abnormalities associated with tadalafil.

Method: EEG recordings from 35 erectile dysfunction patients taking tadalafil (20 mg) were graded for severity of EEG abnormalities (at admission, 2 and 48 hours after tadalafil administration).

Central nerve system toxicity of fluoroquinolones is well known but nearly always benign. Old age, concomittant central nerve system disease, drug interactions and/ or partial or total loss of renal function are the major risk factors. Although, in literature there is very limited number of severe central nerve system toxicity cases related to fluoroqinolones, prompt realization is vital as the only therapy is discontinuation of the drug.

Ureteral stents have been widely used for more than two decades with different indications. Due to the widespread usage of ureteral stents, the number of possible complications of ureteral stents has increased, including stent migration, encrustation, stone formation, and fragmentation. Among these complications, ureteral stent fragmentation is rare.
