The Effect of Bisphosphonates on Bone Mineral Density in Metastatic Prostate Cancer Patients Who Are Treated with Anti-Androgen Drugs and Radiotherapy.

Objective: To evaluate the potential effect of bisphosphonates on bone mineral density (BMD) in patients who are treated with anti-androgen drugs and radiotherapy for metastatic prostate cancer.

Materials And Methods: The data of 31 patients with metastatic prostate cancer who were treated with anti-androgen drugs and radiotherapy during a 1-year period were retrospectively reviewed. Patients were divided in 2 groups, in which 17 patients in group 1 were treated with zoledronic acid (4 mg/month, intravenous) and 14 patients in group 2 who did not receive zoledronic acid.

Recent management of urinary stone disease in a pediatric population.

The incidence of stone disease has been increasing and the risk of recurrent stone formation is high in a pediatric population. It is crucial to use the most effective method with the primary goal of complete stone removal to prevent recurrence from residual fragments. While extracorporeal shock wave lithotripsy (ESWL) is still considered first line therapy in many clinics for urinary tract stones in children, endoscopic techniques are widely preferred due to miniaturization of instruments and evolution of surgical techniques.

Benign phyllodes tumour of the prostate: An extremely rare entity.

Benign phyllodes tumour (BPT) of the prostate is a very rare neoplasm. It is composed of hyperplastic and neoplastic glandular stromal proliferation. Patients with BPT of the prostate generally present with lower urinary tract symptoms and hematuria.

Does the use of smaller Amplatz sheath size reduce complication rates in percutaneous nephrolithotomy?

Purpose: To evaluate the effect of Amplatz sheath size used in percutaneous nephrolithotomy (PCNL) on postoperative outcomes, bleeding and renal impairment rates.

Materials And Methods: We retrospectively evaluated the records of 91 patients who had undergone PCNL. We divided the patients into 2 groups according to Amplatz sheath size (22 and 30 French [F]) used in the PCNL procedure.

A clinical study comparing BIVAP saline vaporization of the prostate with bipolar TURP in patients with prostate volume 30 to 80 mL: Early complications, physiological changes and postoperative follow-up outcomes.

Introduction: We compare BIVAP saline vaporization of the prostate with bipolar transurethral resection of the prostate (TURP) in the treatment of benign prostatic hyperplasia.

Methods: In total, we included 86 patients treated with BIVAP (n = 44) and bipolar TURP (n = 42). The inclusion criteria were maximum urinary flow rate (Qmax) ≤10 mL/s, International Prostate Symptom Score (IPSS) ≥16, and prostate volume measured with transrectal ultrasound scan between 30 and 80 mL.

The stone formation in the Memotherm urethral stent implantation area: Is it a rare complication?

Recurrent urethral stricture is one of the biggest problems in urology. Urethral stents as an alternative treatment has been used since 1985. The stone formation in the Memotherm (Angiomed) urethral stent implantation area is a rare complication.

Long-term results of permanent memotherm urethral stent in the treatment of recurrent bulbar urethral strictures.

Purpose: To evaluate the long term outcomes of permanent Memotherm urethral stent in the treatment of recurrent bulbar urethral stricture.

Materials And Methods: Twenty patients who underwent permanent Memotherm urethral stent implantation due to recurrent bulbar urethral stricture following previous unsuccessful surgical procedure from 1996 to 2002 were included in the study. Long-term outcomes of the patients were evaluated.

Does urinary bladder shape affect urinary flow rate in men with lower urinary tract symptoms?

We aimed to investigate the role of urinary bladder shape which may potentially change with advancing age, increased waist circumference, pelvic ischemia, and loosening of the urachus on bladder emptying and UFR. We retrospectively investigated the medical records of 76 men. The patients were divided into two groups according to bladder shapes in MRI scan (cone and spheric shapes).

The relationship between bladder wall thickness and lower urinary tract symptoms: Does bladder wall thickness change after alpha-blocker therapy with alfuzosin?

Introduction: We evaluate the association between lower urinary tract symptoms (LUTS) and bladder wall thickness (BWT) and investigate whether alfuzosin might improve BWT.

Methods: We retrospectively reviewed the data of 164 patients with LUTS. Patients were divided into 2 groups according to BWT (Group 1: BWT ≤5 mm, n = 69; Group 2: BWT >5 mm, n = 95).

Analysis of radiofrequency ablation of small renal tumors in patients at high anesthetic and surgical risk: urologist experience with follow-up results in the initial six months.

Background: To evaluate the results of various types of radiofrequency ablation (RFA) treatment of renal tumors in patients with excessive anesthetic and surgical risk.

Materials And Methods: Data for RFA performed in in high risk patients were retrospectively evaluated. Other RFA applications in patients with no anesthetic and/or surgical risk were excluded.

BiVap saline vaporization of the prostate in men with benign prostatic hyperplasia: our clinical experience.

Objective: To evaluate the efficacy, safety, and postoperative outcomes of the recently developing endoscopic technique of BiVap saline vaporization of the prostate in patients with benign prostatic obstruction (BPO).

Methods: Ninety-six patients who underwent transurethral resection of the prostate with BiVap system for BPO and with available data during the 1-year postoperative follow-up period were included in the study. All patients were evaluated at the postoperative 1st, 3rd, 6th, and 12th month, and preoperative and postoperative values of International Prostate Symptom Score (IPSS), quality of life (QoL) score, total prostate-specific antigen, International Index of Erectile Function 15, postvoiding residual urinary volume (PVR), maximum urinary flow rate (Qmax), and average urinary flow rate (Qave) were compared.

Unilateral complete ureteral duplication with distal ureteral stone: A rare entity.

Complete duplex ureters opening separately into the urinary bladder is extremely rare; they can be embryologically explained as a development of two ureteral buds separately from a single mesonephric duct. We describe a case of unilateral complete ureteral duplication with distally localized ureteral stone in a 49-year-old male who presented with right flank pain.

Unusual urethral metastasis from colon carcinoma presenting with difficult urination and hematuria.

Urethral metastases originating from the colon are extremely rare. We report a case of a 67-year-old man who presented with difficult urination and hematuria. Diagnostic cystoscopy showed an abnormal, exophytic lesion in his proximal penile urethra a bulbar urethra.

The use of the amplatz sheath in percutaneous nephrolithotomy: does amplatz sheath size matter?

Objectives: To evaluate the effect of Amplatz sheath size used in percutaneous nephrolithotomy (PCNL) on postoperative outcome, bleeding, and renal impairment rates.

Materials And Methods: One-hundred and ten patients who underwent uneventful percutaneous nephrolithotomy between November 2011 and October 2012 were included in the study. The patients were divided into 5 groups based on Amplatz sheath size (22, 24, 26, 28 and 30 Fr).

Nested variant of transitional cell carcinoma with osseous metaplasia of the urinary bladder: a case report and review of published reports.

Nested variant of transitional cell carcinoma (NV-TCC) of the bladder is a rare and relatively new entity. The tumor is aggressive contrasted by its benign histopathologic appearance, and characterized by irregular urothelial nests and/or tubules. Herewith, a case with exceptional osseous metaplasia is presented emphasizing its diagnostic difficulties, because it can be confused with benign diseases or conventional TCC.
