A 39-year-old female previously treated with shock wave lithotripsy developed extensive ureteral stricture disease. After 2 unsuccessful attempts at retrograde balloon dilatation, she was evaluated at our center for further management. Successful reconstruction was performed with laparoscopic-assisted vesicocalicostomy.

Multiple techniques exist to remove uroliths from each section of the urinary tract. Minimally invasive methods for removing lower urinary tract stones include voiding urohydropropulsion, retrograde urohydropropulsion followed by dissolution or removal, catheter retrieval, cystoscopic removal, and cystoscopy-assisted laser lithotripsy and surgery. Laparoscopic cystotomy is less invasive than su...

Renal and ureteric calculi is an uncommon problem in western hemisphere but Pakistan being in the middle of the stone belt has much higher incidence. Open surgery has produced excellent results but the non-invasive lithotripsy and minimally invasive endoscopic management of urinary tract stones has changed the attitudes towards acceptance of open surgery by patients and the relatives. Extracorp...

We have developed a multi-phase compressible fluid solver that can handle shock waves efficiently and accurately. Using a level set formulation to treat sharp interfaces and employing multi-resolution techniques, we can study complex shock-bubble interactions. In this work, shock-induced bubble collapse interactions near a deformable interface are presented as a model for a simplified extracorp...

The introduction of shock wave lithotripsy (SWL) in the early 1980's revolutionized the surgical management for kidney stone disease. Since then, although numerous 2 and 3 r generation lithotripters have been developed using various means for shock wave generation, focusing, patient coupling and stone localization, the technical improvements in these devices were largely made based on practical...

Two patients with renal transplant lithiasis were successfully treated with extracorporeal shock-wave lithotripsy (ESWL) in the prone position. Pathogenesis and treatment of transplant lithiasis are discussed. Performing ESWL on renal transplant patients in the prone position has advantages over standard positioning techniques.

The use of certain technical principles and the selection of favorable cases can optimize the results of extracorporeal shock wave lithotripsy (ESWL). The aim of this study is to review how ESWL works, its indications and contraindications, predictive factors for success, and its complications. A search was conducted on the Pubmed® database between January 1984 and October 2013 using "shock wav...

Relapsing chronic pancreatitis is often caused by elevated pressure within the pancreatic duct due to impaired pancreatic juice outflow in the presence of pancreatic duct stricture or stones formed by chronic pancreatic inflammation. Most of this condition is alcoholic, and patients should stop drinking as a treatment. Alleviating the impaired pancreatic juice outflow and decompressing the panc...

We report a rare case of a patient presenting with scrotal hematoma associated with retroperitoneal hemorrhage after extracorporeal shock wave lithotripsy (ESWL). We propose a mechanism for the formation of scrotal hematoma and its importance as a sign of retroperitoneal hemorrhage.

UNLABELLED Intrathecal (IT) sufentanil provides effective analgesia for extracorporeal shock wave lithotripsy. However, the optimal dose of sufentanil has not been established. We designed a prospective, randomized, double-blinded study to determine the optimal dose of IT sufentanil. Sixty men were randomized to receive 12.5,15,17.5, or 20 microg of IT sufentanil (n = 15 for each group) via a c...
