[Bladder stone secondary to prolene suture after gynecologic surgery].

Urologiia 2018 Dec(5):92-93

Hitit University, Erol Olcok Training and Research Hospital, Department of Urology, Corum, Turkey.

Bladder stones are usually seen among patients with bladder outlet obstruction, especially in men over the age of 50 years. There are several risk factors for bladder stones, including urinary tract infections, abnormal urinary tract system anatomy, and presence of foreign bodies. In addition, migrating intrauterine contraceptive devices through the wall of the urinary bladder and foreign bodies such as surgical sutures may act as a nidus for developing stone formation.

Silodosin: An Update on Efficacy, Safety and Clinical Indications in Urology.

Adv Ther 2019 Jan 6;36(1):1-18. Epub 2018 Dec 6.

Division of Experimental Oncology/Unit of Urology, URI, IRCCS Ospedale San Raffaele, Milan, Italy.

Introduction: Silodosin determines smooth muscle relaxation in bladder and prostate tissues, increases bladder blood flow in conditions of chronic bladder ischemia and regulates the activity of transcriptional factors responsible for stromal growth and prostate hyperplasia. Phase III trials have already demonstrated the efficacy and safety of silodosin in the treatment of patients bothered by lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH).

Objective: We aimed to describe the rationality for the use of silodosin and to summarize the current literature on the use of Silodosin for the treatment of LUTS. Read More

Urethral calculi: A rare cause of acute urinary retention in women.

Turk J Emerg Med 2018 Dec 23;18(4):170-171. Epub 2018 Feb 23.

TOBB Economy and Technology University, Faculty of Medicine, Department of Urology, Yaşam Caddesi No: 5 Söğütözü, 06510, Ankara, Turkey.

Urinary retention is defined as the inability to void; frequently the patient is able to void partially, thus can not completely empty the bladder and diagnosed by increased post-void residual urine (PVR) volumes. It is usually seen in men, but a rare condition in women. The etiological factors may be neurological, anatomical, infectious or pharmacological. Read More

Simplified method using kidney / ureter / bladder x-ray to determine the appropriate length of ureteral stents.

Int Braz J Urol 2018 Nov-Dec;44(6):1224-1233

Department of Urology and Andrology, Kansai Medical University, Osaka, Japan.

Purpose: To investigate a method to determine the appropriate length of ureteral stents, given that the stent length may lead to exacerbation of urinary symptoms if the stent crosses the bladder midline.

Materials And Methods: We retrospectively reviewed the position of the distal curl of the ureteral stent using kidney/ureter/bladder (KUB) radiographs after ureteroscopic lithotripsy in 165 patients who underwent placement of 24- or 26-cm ureteral stents. According to the KUB findings, we categorized the position of the distal curl of the ureteral stent into two groups. Read More
