Pinball calculus in a ureterosigmoidostomy.

We report a complication during the treatment of lithiasis with extracorporeal shock wave lithotripsy in a patient with a ureterosigmoidostomy. This woman presented with renal colic bilaterally and renal insufficiency and was found to have an extremely mobile calculus. A significant gaseous reflux from the sigmoid colon was found to propel the solitary calculus in a retrograde fashion across the ureteroileal anastomosis up the ureter into one kidney, and then later, after re-descent to the level of the anastomosis, up into the opposite kidney.

[Epidemiology of urological emergencies in a teaching hospital].

Objectives: To quantitatively evaluate the emergency activity of a teaching hospital urology department. To determine the epidemiology of urological medical and surgical emergencies.

Material And Method: Single-centre prospective study conducted in one of the 9 teaching hospital urology departments of the Paris region equipped with an emergency room.

CT diagnosis of ureteral fibroepithelial polyps.

We report a case of fibroepithelial polyp of the ureter with serial CT examinations. Progressive growth of the fibroepithelial polyp was documented by CT within a period of 62 months. Excretory phase contrast-enhanced CT images accurately contributed to the diagnosis of ureteral fibroepithelial polyp and allowed limited surgical resection.

[Incontinence and voiding disorders].

Urinary continence and micturition are functions which require the integrity of the organs (bladder, urethra, voluntary and involuntary sphincters) and the neural pathways responsible for micturition (parasympathetic), continence (sympathetic), and their control and coordination. Save the incontinence associated with vesico-vaginal fistulae in women, or overflow incontinence associated with a distended bladder in chronic retention, the three principal clinical forms of incontinence are: stress incontinence, urge incontinence and mixed incontinence, combining the two mechanisms. Voiding difficulties causing discomfort on urination, or even retention (chronic or acute), are the reflection of an imbalance between bladder contraction (reduction) and urethral resistance (augmentation).
