Intermittent testicular torsion presents with recurrent episodes of severe unilateral testicular pain with resolution of symptoms between episodes. We present a case of a 26-year-old man with a 14-year history of intermittent testicular pain presenting to the urology clinic for elective surgical evaluation. He reported monthly symptoms for many years and had learned to manually reduce the torsion with each episode. Diagnosis of intermittent testicular torsion was made based on patient history and treatment with bilateral orchiopexy resulted in complete symptom resolution and without any loss of testicular function...

Ahmed Adam, Jayveer Sookram
Background: To describe a novel bladder fixation technique for use during endoscopic vesicostomy button insertion. Methods: After standard cystoscopic visualization of the bladder, a standard 18 G intravenous cannula was inserted into the bladder. A non-absorbable suture thread was placed through this intravenous cannula under cystoscopic vision. The proximal end of the suture was then removed using standard ureteroscopic grasping forceps (3 Fr) through another needle (15 G) inserted next to the initial puncture site (following a path at 30 degrees from the initial puncture tract) into the bladder...

Objective: To expand the diagnostic armamentarium for medullary sponge kidney (MSK), we evaluate the use of high-resolution multidetector computed tomography (MDCT) for MSK diagnosis and compare to the standard intravenous urography (IVU). Despite a significant prevalence amongst stone formers, diagnosis of this well described condition has declined. IVU, the gold standard in MSK diagnosis, has largely been replaced by CT, which has previously been shown unable to demonstrate signs of MSK...

Overactive bladder (OAB) syndrome is a chronic medical condition which has a major influence on the quality of life in a significant amount of the population. OAB affects performance of daily activities and has an estimated prevalence of 16.5%. Many sufferers do not seek medical help. Moreover, many family physicians and even gynecologists are not familiar with this issue. Usually patients suffer from OAB in advanced age. Nocturia is reported as the most bothersome symptom in the elderly population. The aim of our review was to discuss all aspects of this challenging disorder and suggest tools for assessment and management strategies...

REVIEW

Irritative voiding symptoms (e.g. increased frequency and urgency) occur in many common pathologic conditions such as urinary tract infections and bladder outlet obstruction, and these conditions are well-established to have underlying inflammation that directly triggers these symptoms. However, it remains unclear as to how such diverse stimuli individually generate a common inflammatory process. Jürg Tschopp provided substantial insight into this conundrum when, working with extracts from THP-1 cells, he reported the existence of the inflammasome...
