We describe a patient with a serious urinary tract infection due to Actinomyces bernardiae (formerly classified as CDC [Centers for Disease Control and Prevention, Atlanta] fermentative coryneform group 2). Our patient had long-standing bladder dysfunction and developed hydroureteronephrosis, renal lithiasis, perirenal abscesses, and septicemia. A. bernardiae is distinct from Actinomyces pyogen...

Urolithiasis is the formation of stones in the urinary tract, causing pain and bleeding, and may lead to secondary infection. It is the third most common affliction of the urinary tract. Of many types of stones that are formed, the most common are calcium oxalate. The formation of such concretion encompasses several physicochemical events beginning with crystal nucleation, growth, aggregation, ...

OBJECTIVE Urinary lithiasis affects between five and 10% of the human population during their lifetime, only 2-3% of whom are children. Therapy of urolithiasis in the pediatric age group with minimally invasive methodology represents an attractive alternative. This study presents results of extracorporeal shockwave lithotripsy, a minimally invasive methodology, for the treatment of urinary lith...

Urinary stone formation is one of the oldest and most widespread diseases known to man. The disease has a multifactorial etiology that includes anatomic, environmental, genetic, infectious, metabolic, nutritional, importantly socio-economic factors. It caused by biochemical imbalance in urine between stone-forming inhibitors promotors process as lithogenesis. mechanisms underlying development u...

We evaluate the efficacy of ESWL in the management of calculi in patients with urinary diversion. We treated 5 patients who suffered from urinary lithiasis after urinary diversion post cistectomy. We managed the patients with extracorporeal shock wave lithotripsy in monotherapy with a Siemens Lithostar Modularis device. Mean stone size (long axis) was 1.95 cm (range 1 to 3.5 cm). The mean shock...

tion in solution. For many years it has been used in medical practice, chiefly as a urinary antiseptic, though its value in this latter connection is very much open to doubt. In contact with the blood stream, it is supposed that the drug liberates formalin, and that its antiseptic action is due to this. The drug has also been tried in several other conditions, such! as lithiasis, rheumatism, go...

Pelvic ectopic kidney associated with giant hydronephrosis is rare. It may be responsible for an extrinsic compression of adjacent structures. The authors report a case of giant hydronephrosis on a left pelvic ectopic kidney caused by obstructive lithiasis in a patient of 25 years. First ultrasound guided percutaneous nephrostomy allowed urinary drainage. Definitive treatment consisted in nephr...

Ureteritis cystica is an uncommon cause of acute renal pain. The aetiology remains unclear and the diagnosis may be difficult to establish. We report the case of a 29 year old woman with a history of repeated urinary tract infections presenting with acute renal colic in the absence of lithiasis. We review the diagnostic tools available to make the diagnosis and the recent pertinent literature.
