Synchronous primary malignancies of the male urogenital tract.

The finding of prostate cancer after a cystoprostatectomy for a bladder tumour can occur in up to 70% of cases. The incidence of prostate cancer in patients with a bladder tumour is 18 times higher than in the general population; moreover, the incidence of bladder cancer in patients with prostate cancer is 19 times higher than in the general population. This association can be explained by the common embryological origin of these organs, with molecular similarities.

Transurethral transvesical endoscopic management of a retrovesical hydatid cyst.

We present a technique of transurethral transvesical endoscopic management of an intraperitoneal retrovesical hydatid cyst. Cystoscopy is performed using a 20.8F nephroscope.

A more "conventional" way to perform percutaneous endopyeloplasty: a feasibility study.

Objective: Percutaneous endopyeloplasty is a horizontal suturing of the endopyelotomy incision via a unique percutaneous tract. We present a feasibility study of our technique of percutaneous endopyeloplasty using a conventional suture with a laparoscopic needle holder via the nephroscope.

Materials And Methods: A longitudinal endopyelotomy incision is performed through a 24-Fr working sheath placed via an upper calyx.

Needle renal displacement technique for the percutaneous approach to the superior calix.

We describe a new renal displacement technique using an 18-gauge needle to facilitate superior calix puncture and consequently to decrease intrathoracic morbidity. Initially, a lower or middle calix is punctured with an 18-gauge needle. Then, the proximal end of the needle is progressively pushed in the cephalic direction.

Endoscopic replacement of the amplatz sheath with a larger one, for larger stone fragments extraction.

We present a technique to replace a 24F with a 30F working sheath during percutaneous renal surgery, for larger stone fragments extraction. To gain time, the 30F sheath is directly glided over the 24F sheath under endoscopic control, without radiation exposure.

The split-leg modified lateral position for percutaneous renal surgery and optimal retrograde access to the upper urinary tract.

Objectives: To present our experience with percutaneous nephrolithotomy (PCNL) in the split-leg modified lateral position.

Material And Method: The patient is placed with the thorax in the lateral position and the pelvis in an oblique position. Then the lower limbs are split and bent in the lowest position.

A vacuum cleaner for the pelvicalyceal system during percutaneous nephrolithotomy.

Removing small stones, fragments and debris, clots, or clusters of small stones can be bothersome and time consuming. We perform a technique to sweep out fragments from the kidney during percutaneous nephrolithotomy using suction. The nephroscope is used as a vacuum cleaner by adapting the suction tube to the nephroscope operating channel.
