Renal cell carcinoma of native kidney in renal transplant recipients.

Objective: To evaluate the prevalence, prognosis and possible risk factors of renal cell carcinoma (RCC) of the native kidney in renal transplant recipients.

Patients And Methods: We retrospectively re-examined the follow-up data of 373 consecutive renal transplant recipients at our institution between August 1993 and September 2004. We collected the data of all de novo RCC of the native kidney in the current analysis.

Laparoscopic excision of seminal vesicle cyst revealed by obstruction urinary symptoms.

Primary diseases of the seminal vesicle are rare. Most seminal vesicle cysts are congenital, and two-thirds are associated with renal dysplasia or agenesis and ectopic ureter opening into the seminal vesicle. Acquired cysts may be due to genitourinary infections, surgical prostate resection or ejaculatory duct lithiasis.

Impact on active scope deflection and irrigation flow of all endoscopic working tools during flexible ureteroscopy.

Objective: Flexible ureteroscopy is nowadays an alternative effective option for treatment of upper urinary tract stones, especially in the lower renal pole. Access in this case is often limited by active deflection capabilities of the instrument which is always deteriorated by the passage of different tools through the working channel. Insertion of them limits also the irrigation flow and so that the visibility.

[Flexible double active deflection ureterorenoscopy].

Introduction And Objective: Secondary deflection of a flexible ureterorenoscope (FUR) is a passive mechanism, which can only be performed under certain anatomical conditions. The objective of this study was to present a new double active deflection FUR and to assess its value based on our initial experience.

Material And Methods: From October 2002 to February 2003, we performed flexible retrograde ureterorenoscopy in 30 consecutive patients (34 renal units) using a double active deflection FUR (ACMI DUR 8 Elite).

Emergency extracorporeal shock wave lithotripsy (ESWL) for obstructing ureteral stones.

Objective: To evaluate emergency treatment of obstructing ureteral stones by in situ extracorporeal shock wave lithotripsy (ESWL) during acute renal colic.

Patients And Methods: From January 1994 to February 2000, 200 patients (mean age: 42 years) were treated by ESWL (EDAP LT-02) for obstructing ureteral stones causing acute renal colic refractory to medical treatment or recurring within 24hours of such treatment. Stones were visualised by fluoroscopic imaging and/or ultrasound.
